Conventional mergers of this type of tank are, for example,
As shown in Figure 2, it is a tubular body that is approximately T-shaped with openings a, b, and c on three sides,
As shown in Figure 1, a pair of openings in opposing directions are used as connection ports a and b, which are connected to a pair of tanks d and e through pipes f and g, respectively, and the remaining opening c is connected to a pump h. It is configured to be connected to a water inlet or the like through a pipe i.

However, in the conventional merger, as shown in FIG. 13 or FIG. In this case, as shown in both figures, there is a problem in that fluid moves from one tank to the other tank via this merger, further disrupting the balance of the centers of gravity of both tanks d and e.

Therefore, this applicant disclosed a tank merger that solves this problem in an earlier utility model registration application (Utility Model Application No. 156172/1982 [Publication of Utility Model Application No. 63472/1983]). According to this, a branch chamber is formed in the main body and communicates with a pair of tanks or vessels through a pair of connection ports, a valve seat is formed in each of the pair of connection ports of the branch chamber, and a bottom portion of the branch chamber is formed with a valve seat. A recess is formed in the recess provided with a guide consisting of an upward slope toward the respective valve seats, and the recess is provided with a guide that is movable freely along the guide and is seated on the respective valve seats. A fluid valve body is provided loosely, and a port is formed in the main body to communicate the branch chamber with the outside, thereby preventing fluid from rapidly moving from one tank to the other tank. can.

[The problem that the idea aims to solve]

However, the liquid introduced into the branching chamber is contaminated with sediment, and if such sediment accumulates in the recess, it will hinder the smooth rolling of the valve body in the guide of the recess. There is.

This invention relates to the improvement of the above-mentioned utility model registration application, and aims to provide a tank junction that can prevent deposits from accumulating in recesses and discharge such deposits to the outside.

[Means to solve the problem]

A branch chamber is formed in the main body to communicate with a pair of tanks or vessels through a pair of connection ports, a valve seat is formed in each of the pair of connection ports of this branch chamber, and a valve seat is formed in the bottom of the branch chamber. A recess is formed with a guide having an upward slope toward the valve seats, and a valve body is provided in the recess, which is movable freely along the guide and can be seated on each of the valve seats. In a junction of a tank, in which a flow outlet is formed in the main body to communicate the branch chamber with the outside, a groove that opens into the recess at the upper side and extends along the recess is connected to the recess. , the groove is configured to be able to communicate downwardly to the outside through a discharge port formed in the lower part of the main body, and a stopper is removably attached to the discharge port. This is what we propose.

Therefore, in the tank confluencer according to this invention,
A groove is formed in the recess that opens into the recess at the top and extends along the recess, and this groove can communicate with the outside through a discharge port formed at the bottom of the main body. is attached removably.

〔Example〕

An embodiment of this invention will be described below based on the accompanying drawings.

FIG. 1 is a sectional view showing a confluencer of the tank of this invention, and FIGS. 2 and 3 are sectional views taken along the line A-A and B-B shown in FIG. , 1 is a block-shaped main body, and a branch chamber 2 is formed in the main body 1. Connecting ports 3 and 4 are formed in side walls 2a and 2b that are substantially opposite to each other in the branching chamber 2, and these connecting ports 3 and 4 are connected to a pair of tanks 5 in which fluid is stored, respectively, as shown in FIG. ，
6 via conduits 7 and 8. Valve seats 9 and 10 are formed in both the connecting ports 3 and 4, respectively.

A recess 11 is formed in the bottom 2c of the branch chamber 2 and is provided with a guide 11a having a curved cross section including an arc and having an upward slope toward the valve seats 9 and 10.

Both valve seats 9 and 10 are inserted into the branch chamber 2 through an insertion port 13 that can be opened and closed by a plug 12 formed in the upper part and connected with a screw.
A spherical valve body 14 that can be seated on the guide 11
It is freely installed to be movable along a. Note that the valve body 14
can be made of steel, synthetic resin or ceramic. Further, an outflow port 17 is formed in a side portion of the main body 1, which is an opening through which the branch chamber 2 and an external pump 15 etc. are communicated via a conduit 16 (shown in the fifth figure).

The groove 11b, which opens upward, extends along the entire length of the recess 11 and connects the valve body 14.
has a width less than the diameter of The outlet 18 is bored at the center of the lower part of the main body 1, and the groove 11b is formed at the center in the longitudinal direction, that is, at the bottom of the lowermost part.
It communicates with the upper end of 8. The plug 19 is screwed to the outlet 18 so that it can be opened and closed.

FIG. 4 illustrates various shapes of the recess 11 and the groove 11b. In FIG. 2, the grooves 11b have the same width in the height direction, but in FIG. 4a, the grooves 11b are narrow only at the upper end, and have the same width as the recess 11 except for the upper end. In Fig. 4b, recess 1
A cross section in the width direction of No. 1 is formed into a downwardly convex curved surface. In FIG. 4c, the grooves 11b are arranged in parallel on both sides of the recess 11 in the width direction.

Since the tank merging element of this invention is as described above, as shown in Fig. 5 or 6, if both tanks 5 and 6 are tilted to one side for some reason, or if one side has inertia Even when a force is applied, the valve body 14 in the branch chamber 2 is tilted and is seated on the lower valve seat, for example, the valve seat 9, and the branch chamber 2 is removed from the upper tank 6. The flow of fluid to the other tank 5 is stopped through the tank 5, and a substantially equal amount is maintained in both tanks 5 and 6 on the slope, and the balance of the centers of gravity of both tanks 5 and 6 is maintained. It is said to be in a state of

For example, as shown in FIG.
1, that is, the chemical liquid tanks 25 and 26 respectively provided on the left and right sides of the flight means 21 are connected to each other via the junction of this invention, and the chemical liquid dispersing pump ( (not shown). In this case, as shown in FIG. 7, even if the flight means 21 is tilted to one side, the chemical liquid will be on one side (the amount of chemical liquid in the tank is shown by a broken line) as in the case of using the conventional one. The chemical dispersion device 22 equipped with the flight means 21 can prevent a large amount of liquid from flowing into the tank 26, and can maintain the amount of chemical liquid in the tanks 25 and 26 in a balanced state before tilting as shown by the solid line. This will help prevent you from losing your balance.

Furthermore, as shown in FIG. 8, it is also possible to use it in a two-tank type chemical liquid tank car in which the interior of the tank body 31, which can be driven on wheels 30, is divided into two tanks 35 and 36 by a partition wall 32. Specifically, by communicating the connecting ports 3 and 4 with the tanks 35 and 36, respectively, and closing the outflow port 17 with a valve, etc., when an inertial force acting on one side of the chemical tank car is applied, However, as shown in FIG. 10, the chemical liquid moves into one tank 36 (the amount of chemical liquid is shown by the broken line) as in the case of using the conventional type, and the balance of the centers of gravity of both tanks 35 and 36 is maintained. It does not collapse, and as shown by the solid line in the same figure, the amount of chemical liquid before the inertial force is applied is maintained, and the balance of the center of gravity of the entire chemical liquid tank car is maintained.

A plug 12 is provided in the upper part of the main body 1, and a hole (insertion port) is provided in the upper part of the main body 1 to make it possible to insert the valve body 14 into the branching chamber 2 or to replace the valve body 14 that has become corroded or has a chemical adhered to it. 13).

In FIG. 1, when the liquid in the tank moves from one communication port 3 to the other connection port 4, the liquid flowing in the branch chamber 2 pushes the valve body 14 and is directed toward the valve seat 10 on the other side. However, in the case of FIGS. 4a and 4b showing an example of the groove 11b, the apparent diameter of the valve body 14 in the rolling direction becomes smaller due to contact with the guide 11a, so that its original diameter is reduced. Since the rolling time is longer than in the case of FIG. 4c where the groove contacts the recess, the groove shape can be used depending on the type of liquid and the size of the branching chamber.

Precipitates and the like are mixed in the liquid such as the medicine introduced into the branching chamber 2, and although these precipitates settle, they do not accumulate in the recess 11, but instead pass through the recess 11 and settle. and is deposited there. The deposits and the like accumulated in this groove 11b are discharged to the outside through the discharge port 18 when the lower stopper 19 is opened. At this time, the plug 12 and the outlet 18 on the top of the main body 1
By opening the stopper 19 and passing the washing liquid into the branching chamber through the insertion port 13, the precipitate can be easily discharged.

[Effect of idea]

As described above, according to this invention, a groove is formed in the recess that opens into the recess at the top and extends along the recess, so that the precipitates mixed in the liquid introduced into the branching chamber are prevented from entering the recess. It passes through the recess and reaches the groove without depositing, and even if sediment accumulates in the recess, it can be easily removed into the groove by rolling the valve body, ensuring a sediment-free valve passage at all times. .
