Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a device for joining a socket with a tank, such as a relatively small capacity tank such as an oil blocking tank installed in a kitchen facility.
It is effective when applied to cases made of non-metallic materials such as P material (reinforced plastic).

(Prior Art and its Problems) In the oil blocking tank as described above, a socket is connected to the peripheral wall of the tank so as to pass through the tank, and a discharge pipe is connected to the socket. Conventionally, when tanks are made of non-metallic materials such as FRP materials, it is not possible to weld the sockets as with metal tanks, so a socket made of vinyl chloride is used and is glued to the surrounding wall of the tank. For this reason, not only is the work of joining the tank and the socket troublesome, but also there is a problem that cracks occur in the joint due to vibrations such as earthquakes, and water leaks easily.

This invention was made to solve the above-mentioned conventional problems, and its purpose is to provide a tank-to-socket joining device that facilitates joining work and has excellent watertightness against vibrations such as earthquakes. shall be.

(Means for Solving the Problems) This invention for solving the above problems and achieving the objects has a cylindrical part with a threaded part formed on the inner peripheral surface, and one end of the cylindrical part has a threaded part formed in the radial direction. A plurality of extending flange pieces are provided radially, an annular flange is provided at the other end, a socket in which each flange piece is provided with a threaded hole, a pair of packing rings, a center hole and a radially extending flange around the socket. The socket includes a pressing ring having a plurality of radially extending slots through which the flange pieces can pass, and a pressing bolt screwed into a threaded hole in the flange piece, and the socket is provided on a peripheral wall of the tank. It is inserted into the hole, one packing ring is placed between the annular flange and the circumferential wall of the tank, the other packing ring and the pressure ring are located between the flange piece and the circumferential wall of the tank, and the pressure ring is located on one side of the flange. Further, the slots of the press ring and the flange pieces are arranged so as not to overlap, the press bolt abuts the end face of the press ring, and the peripheral wall of the tank is sandwiched between the pair of packing rings. There is a connection device between the tank and the socket.

(Function) Watertightness between the tank and the socket is achieved by one packing ring placed between the annular flange and the tank circumferential wall, and the other packing ring placed between the flange piece and the tank circumferential wall. held by a ring. At this time, the other packing ring is pressed by the pressing bolt through the pressing ring, and the peripheral wall of the tank is held between the pair of packing rings.

According to such a joining device, there is no need for conventional bonding, and the packing ring absorbs vibrations during an earthquake.

(Example) As shown in FIG. 1, 1 is a tank made of FRP material, and the peripheral wall of the tank 1 is inclined.

As shown in FIGS. 2 and 3, the socket 2 has a cylindrical portion 3 with a threaded portion 4 formed on its inner peripheral surface, and a plurality of radially extending flange pieces 5 at one end of the cylindrical portion 3. It is provided radially and has an annular flange 7 at the other end.
are provided, and each flange piece 5 is provided with a screw hole 6.

As shown in FIGS. 4 and 5, the rubber packing ring 8 has a center hole 9, and a plurality of groove holes 9a are radially provided around the center hole 9, extending in the radial direction through which the flange pieces 5 can pass. . Also Patsukin ring 8
Annular protrusions 10 and 11 are provided on the outer periphery of the center hole 9 and on the peripheries of the center hole 9 and the slot 9a, respectively. This packing ring 8 has one end surface inclined so as to follow the peripheral wall of the tank 1, and its wall thickness gradually decreases.

As shown in FIGS. 6 and 7, the press ring 12 has a center hole 13, and a plurality of slots 13a extending in the radial direction around the center hole through which the flange pieces 5 can pass are provided, and bolts are inserted between the slots 13a. A recess 14 is provided for receiving the tip of 15.

When joining the tank 1 and the socket 2, as shown in FIG. The piece 5 is inserted into a hole 16 through which it can pass.

Next, attach the other packing ring 8 and press ring 12 to the socket 2 in sequence, and then press the press ring 12.
is rotated so that the recess 14 and the screw hole 6 of the flange piece 5 are aligned. Then, a bolt 15 is screwed into the screw hole 6, and its tip is inserted into the recess 14 to press the end surface of the pressing flange 12. As a result, the packing ring 8 is pressed, and the peripheral wall of the tank 1 is sandwiched between the pair of packing rings 8.

17 is a discharge pipe screwed onto the socket 2.

(Effects of the Invention) As described above, according to the present invention, the socket is joined to the tank through the cooperation of the pair of packing rings, the pressing flange, and the pressing bolt, so there is no need for conventional adhesives, and there is no need for joining. can be done easily. In addition, the packing ring absorbs vibrations during earthquakes and improves earthquake resistance, so water leakage can be prevented.
