Abstract
The utility model discloses a safety valve for a liquefied gas cylinder, which comprises a valve body, and the internal part of an air outlet of the valve body is provided with a safety valve. The safety valve for a liquefied gas cylinder is composed of a valve core, a valve seat, a spring, and a limiter, wherein, the valve seat is provided with an external thread which is matched with an internal thread in the air outlet of the valve body; the center is provided with a venting hole; the valve core and the limiter are connected in the venting hole in the center of the valve seat, and the spring is arranged between the limiter and the valve seat. The utility model has the characteristics of simple structure, safe and durable property, strong reliability, etc.
Description
The utility model relates to a kind of gas valve, specifically a kind of cylinder for liquefied gas relief valve.
Existing cylinder for liquefied gas valve generally is made up of valve body, suction port, air outlet, turn-knob, and suction port connects steel cylinder, and the air outlet is connected with decompressor.The valve of this structure is not when connecing decompressor, as long as turn-knob is loosening, the gas in the steel cylinder will leak by the air outlet.The user opens valve just can fall raffinate, breaking out of fire easily, and turn-knob is loosening to leak gas because of vibration makes in transportation process to fill the steel cylinder of gas, accidents caused easily.
The purpose of this utility model provides a kind of simple in structure, safe and reliable cylinder for liquefied gas relief valve.
The utility model is to realize its goal of the invention by the following technical solutions, the cylinder for liquefied gas relief valve, and it comprises valve body, is provided with relief valve in the air outlet of valve body, described relief valve is made up of spool, valve seat, spring, snubber.Wherein valve seat is provided with the outside thread that matches with internal thread in the valve body air outlet, and is provided with vent at the center, and spool is connected with snubber in the center roof vent that is located at valve seat, and spring is located between snubber and the valve seat.
Because adopt above technological scheme, the utility model has ideally been realized its goal of the invention, and have characteristics such as simple in structure, safety durable, good reliability.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is further described: the cylinder for liquefied gas relief valve, it comprises valve body, in the air outlet of valve body, be provided with relief valve, described relief valve is made up of spool 1, valve seat 2, spring 4, snubber 3, wherein valve seat 2 is provided with the outside thread that matches with internal thread in the valve body air outlet, and be provided with vent at the center, and spool 1 is connected with snubber 3 and is located in the center roof vent of valve seat 2, and spring 4 is located between snubber 3 and the valve seat 2.For relief valve is sealed better, between spool 1 and valve seat 2, be provided with sealing gasket 5, between valve seat 2 and valve body air outlet, be provided with seal ring 6.Spool 1 one ends are with in snubber 3 is connected the center roof vent that places valve seat 2, the other end covers on the external port of valve seat 2 center roof vents, work to close gas, the movement travel of snubber 3 control spools 1, and prevent that spool 1 from falling in the valve body, because spool 1 is in closed condition under the effect of spring 4 and snubber 3, so the gas in valve is in open mode steel cylinder of following time can not leak yet, and the pressure in the steel cylinder is big more, spool 1 is closed tight more, have only when the air outlet of valve body and connect decompressor, the joint of decompressor backs down spool 1 by snubber 3, and the gas in the steel cylinder just can come out.
The utility model also is fit to other gas valves of control.
