Abstract

PURPOSE:To improve safety by housing a take-out valve and a charging valve consisting of solenoid valves in a tank, in a tank for a car, etc. CONSTITUTION:A take-out valve 2 opens a plunger 11 by electrifying a magnetic coil 13. Thereby, a fuel liquid flows out, through an excessive flow preventing valve 20, via a fuel inlet pipe 16 and a fuel outlet pipe 9, and through a fuel feeding port 8. At this time, fuel passes around a coil liner 14 and absorbs heat developed in the solenoid coil 13. A charging valve 3 also formed in a similar manner, opens a plunger by electrifying a solenoid valve. By this construction, safety can be improved.

Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a tank equipped with a built-in valve that is useful for preventing fires and other disasters that may occur when a tank installed in an automobile, vehicle for transporting hazardous materials, etc. is damaged. .

2. Description of the Related Art Conventionally, in a fuel tank of an automobile or a tank of a tank lorry, a fuel transport wagon, a dangerous goods transport vehicle, etc., there is a take-out valve (A) and a fill valve for the fuel or chemical liquid, etc. of the tank, as shown in Fig. 4. (B) and the safety valve (C) were attached to the tank body (D) in a protruding state.

Problems to be Solved by the Invention As mentioned above, conventional tanks for automobiles, etc. have a take-out valve,
The filling valve and safety valve protrude outside the tank body, so in the event of a car collision or rollover accident, the tank body has a strong cylindrical structure and will not be destroyed. However, these valves, which are installed protruding from the tank body, may be damaged or the handle to close the valve may become inoperable, causing the fuel or chemical liquid inside the tank to leak, causing a fire or causing the chemical liquid to leak out. There was a problem in that it could cause a major disaster due to fire (or mouth, etc.).

Means for Solving the Problems In order to solve the above problems, the present invention provides a solenoid valve (10
), (23), a take-out valve (2) and a filling valve (3)
) is stored inside the tank (1).

For production The operation of the invention will be explained with reference to embodiments of the invention.

In the take-out valve (2), when the electromagnetic coil (13) is energized, the normally closed plunger (11) opens and the fuel liquid passes through the overflow prevention valve (20) and enters the fuel inlet pipe (1).
6), the fuel flows out through the fuel outlet pipe (9) and the fuel supply port (8) to a required location outside. In this case, during normal use, the electromagnetic coil (13) is energized for a long time, so the amount of heat generated by the electromagnetic coil (13) increases, which increases the temperature of the fuel in the tank (1), thereby increasing the pressure in the tank. To prevent this, the fuel liquid is passed around the coil liner (14), thereby cooling the electromagnetic coil (13), and the heated fuel liquid flows out to the outside. It has become.

If the electric wire (15) is cut due to an accident, etc., the solenoid valve (
10) is closed by the force of the spring (12) since the electromagnetic coil (13) does not operate, thereby preventing fuel from flowing out.

As is well known in the art, when an abnormally large amount of fuel fluid flows in the overflow prevention valve (20), the fuel fluid pushes the closing plate (19) more than the force of the spring (18), causing the closing plate ( 19)
acts to prevent excessive outflow of fuel liquid by closing the space between the valve holder and the outside (17).

In the filling valve (3), when the electromagnetic valve (23) is energized, the normally closed plunger opens and the fuel liquid passes through the fuel filling port (21) and flows from the fuel inlet pipe (22) to the fuel outlet pipe (24). ) and the overfill prevention device (26>) to fill the tank (1).In this case, since the fuel filling time is a certain short time, the heat generated by the electromagnetic coil will not affect the pressure inside the tank. There isn't.

If the electric wire (15) is cut due to an accident or the like, the electromagnetic valve will be opened by the force of the spring because the electromagnetic coil will not operate, and the fuel will not flow backwards and flow out.

As is conventionally known, the overfill prevention device (26) prevents overfill by moving a float up and down according to the fuel level and opening and closing a valve accordingly.

When repairing or inspecting the take-out valve (2), filling valve (3), overflow prevention valve (20), and overfill prevention device (26),
Installing the tank wall (4) 7 From the lunge (5) to the lid plate (6)
) can be removed by removing.

Example An embodiment of the invention will be described with reference to the drawings.

In Figure 1, (1) is a tank, and the take-out valve (2
) and the filling valve (3) are located inside the tank (1), and the wall (4) is attached to the flange (5) by tightening the cover plate (6) with bolts (7).

Figure 2 shows the details of the fuel liquid take-off valve (2). ) are drilled. (9) is a fuel outlet pipe, and a solenoid valve (10) is connected to the lower end thereof. The solenoid valve (10) has a plunger (11) in the center that is always held by a spring (12).
1) is wound so as to press it against the lower valve seat (11'), and an electromagnetic coil (
13) is covered with a stainless steel coil liner (14), and an electric wire (15) from the electromagnetic coil (13) passes through a conduit (15') and connects to the outside of the tank wall (4). A fuel inlet pipe (16) is provided at the end of the fuel inlet pipe (16), and a spring (18) is wound between the tip and the outside of the valve holder (17) so as to constantly press the closing plate (19) downward. A prevention valve (20) is provided in series.

Figure 3 shows the details of the fuel liquid filling valve (3), and the tank wall (4) is attached by connecting the fuel filling port (21) to the lid plate (6) attached to the flange (5). It is perforated. (22) is a fuel inlet pipe, and a solenoid valve (23), which is the same as the take-out valve (2), is connected to the lower end of the fuel inlet pipe. Solenoid valve (23
) is provided with a fuel outlet pipe (24) at its lower end, and at its tip there is a conventional overfill prevention device (25) equipped with a float (25).
26) are installed in series.

Effects of the Invention This invention has the advantage that even if a collision occurs, the tank body has a strong structure, so it will hardly be destroyed, and the take-out valve and filling valve, which are easily destroyed, are housed inside the tank body. In addition, the take-out valve and filling valve, which can normally be operated by energizing from outside the tank, are designed so that even if the electric wire is cut due to an accident, the solenoid valve will not be damaged. There is no leakage of fuel, etc., and there is no possibility of a fire causing a major disaster or a disaster caused by a chemical solution, etc.
