Abstract
The invention discloses a quick closing valve box, which comprises a control box body (10) and an air bottle (1), wherein the air bottle (1) is arranged in the control box body (10). A safety valve (2), a discharge valve (3) and an air inlet valve (4) are arranged on the air bottle (1). A ball valve (5) is connected on the air bottle (1). The air bottle (1) is communicated with a quick closing valve through the ball valve (5). A pressure relief device (6) is arranged on an air outlet branch between the air bottle (1) and the quick closing valve. The invention has the advantages that the structure is simple, the cost is low, the operation is convenient and the quick closing valve box can be widely used on all kinds of large and small ships.
Description
Technical field
The present invention relates to a kind of quick closing valve case that easy to operate and low-cost pressure relief device are housed.In when, on the ship fire disaster taking place when, can open the valve of giving vent to anger in the quick closing valve case immediately, so that output compressed air makes the fast valve of cargo tank oil-out close rapidly, cut off oil circuit, prevent the leakage of fuel oil effectively, cause fire spread, avoid heavy losses.
Background technology
At present, the quick closing valve control cabinet on the domestic market does not all provide the pressure relief device of export pipeline.This quick closing valve control cabinet
When opening quick closing valve control cabinet air outlet valve, compressed air makes the cargo tank fast valve close rapidly, cuts off oil circuit.After potential safety hazard is eliminated, the quick closing valve control cabinet need be recovered original state, but still keep the pressure of 0.3MPa at least in the outlet pipe this moment, fast valve will reset just very difficult, so the compressed air in the pipeline must be released.Though the quick closing valve control cabinet of external minority manufacturer production provides pressure relief device, they are that the triple valve that adopts is realized, so there are some drawbacks, involve great expense, and it is big to take up room, and the gas of small dimension all need customize with triple valve.
Summary of the invention
At the deficiencies in the prior art, the invention provides a kind of quick closing valve case that easy to operate and low-cost pressure relief device are housed, pressure relief device is small and exquisite, simple and easy, cost is low, can be directly installed on going out on the gas branch pipe in the quick closing valve control cabinet, the compressed air of just can releasing press...withes one's finger, bleeder port can change direction as required, is unlikely to operating personnel are caused any harm.
The present invention has adopted following technical scheme: a kind of quick closing valve case, comprise the control cabinet body and be positioned at the intrinsic air bottle of control cabinet, described air bottle is provided with safety valve, discharge valve and intake valve, also be connected with ball valve on the described air bottle, described air bottle is connected with fast valve by ball valve, and pressure relief device is located at going out on the gas branch pipe between air bottle and fast valve.
Described pressure relief device is made up of valve seat, spool, spring, and described spool links to each other with valve seat by spring, also is provided with through hole on the described valve seat; Described pressure relief device is positioned at going out on the gas branch pipe that the ball valve rear end links to each other with fast valve; Be provided with pressure gauge valve between described ball valve and air bottle; Also be provided with pressure gauge valve on the described air bottle, an end of pressure gauge valve is connected with pressure controller and Pressure gauge; Be provided with side by side between described air bottle and fast valve somely to go out on the gas branch pipe, ball valve and pressure relief device are arranged on every and go out on the gas branch pipe.
The present invention has following beneficial effect: the present invention is simple in structure, cost is low, be convenient to operation, and can be applicable on the boats and ships of all size.

The specific embodiment
As shown in Figures 1 and 2, a kind of quick closing valve case comprises control cabinet body 10 and the air bottle 1 that is positioned at control cabinet body 10, and described air bottle 1 is provided with safety valve 2, discharge valve 3, intake valve 4, pressure gauge valve 7, an end of pressure gauge valve 7 is connected with pressure controller 8 and Pressure gauge 9.Also be connected with ball valve 5 on the air bottle 1, air bottle 1 is connected with fast valve by ball valve 5, and 1 of ball valve 5 and air bottle are provided with pressure gauge valve 7.Pressure relief device 6 is made up of valve seat 11, spool 12, spring 13, and described spool 12 links to each other with valve seat 11 by spring 13, and also being provided with through hole 14 on the valve seat 11 is the aperture of a 2mm, uses as venting.Valve seat is made by copper hexagonal rod car, and the plug core is made by copper pole car, and spring 13, plug core 12 and valve seat 11 are assembled into one, and just constitutes an easy pressure relief device.Pressure relief device 6 is located at going out on the gas branch pipe between air bottle 1 and fast valve.On the pipeline that goes out gas branch pipe upper ball valve 5 rear ends, be welded with nipple, directly pressure relief device 6 be screwed on the nipple.Be provided with side by side between air bottle 1 and fast valve somely to go out on the gas branch pipe, ball valve 5 and pressure relief device 6 are arranged on every and go out on the gas branch pipe.
When sending alarm of fire on the ship, associated responsibilities personnel can open chamber door rapidly, perhaps the hammer that carries of operative installations is broken the glass on the door into pieces, all ball valve 5 on the manual unlocking export pipeline, the compressed air of air bottle can be expanded to the cargo tank fast valve rapidly, make fast valve close rapidly, cut off oil circuit.
After fire is eliminated, close that all go out the ball valve 5 on the gas branch pipe in the case, pin pressure relief device 6 then respectively, the compressed air in the pipeline promptly can be released out easily, and operating personnel can return to fast valve the state before the fire this moment.After waiting the work of this device to cross once, next operating personnel can replenish the compressed air of sufficient amount as required by checking Pressure gauge in air bottle, close upper chamber door, recover the preceding duty of fire.
