a container valve

Abstract

The invention discloses a container valve. The container valve comprises a parent body and a lower valve body connected with the bottom of the parent body; an upper air inlet channel and an upper air outlet channel are formed inside the parent body, and the upper air inlet channel is communicated with the upper air outlet channel; the lower valve body is internally provided with a lower air inlet, a lower air outlet, an air inflation device, an execution channel and a piston; a protrusion for dividing the execution channel into an upper channel section and a lower channel section is arranged in the execution channel, and the piston is matched with the upper channel section and located in the upper channel section to perform reciprocating motion in the axial direction of the execution channel; the upper channel section is communicated with the upper air inlet channel, and the lower channel section is communicated with the lower air inlet and the air inflation device; and the lower air outlet is communicated with the execution channel at the section position where the corresponding piston performs the reciprocating motion. The container valve has the beneficial effects that after being started, the container valve can be recovered to be used without replacing a diaphragm, and multiple driving modes are achieved; the using scope of the container valve is enlarged, and the sealing degree of the container valve is improved; and the conditions that air in the container valve exceeds the pressure or is insufficient in pressure are avoided.

Description

technical field [0001] The invention relates to the field of valves, in particular to a container valve. Background technique [0002] The container valve is usually used to seal the gas fire extinguishing agent, open and release the gas fire extinguishing agent in case of fire; therefore, the design of the container valve should meet the actual needs of the gas fire extinguishing system, that is, according to the specific conditions of the system such as: location, environmental conditions, etc., To make it work reliably for a long time, there should be no malfunction and excessive leakage. [0003] However, most of the existing container valves have the following problems: [0004] 1. After the diaphragm in the valve of the container valve is pierced, it is necessary for professionals to dismantle the valve body and replace the diaphragm before it can be restored to use; [0005] 2. Since domestic cylinder sets need to be equipped with independent starting cylinders and ...

AI Technical Summary

Problems solved by technology

[0004] 1. After the diaphragm in the valve of the container valve is pierced, it is necessary for professionals to dismantle the valve body and replace the diaphragm before it can be restored to use;

[0005] 2. Since the domestic cylinder group needs to be equipped with independent starting cylinders and pneumatic components, the fire-fighting equipment usually consists of more accessories and requires larger installation controls, which leads to too many leak points and affects the fire-fighting effect of the fire-fighting equipment

[0006] 3. The existing container valve body is difficult to ensure the safety of valve body installation and transportation, and when the pressure gas inside the container valve is overpressured or underpressured, effective protection or supplementation cannot be obtained.

[0007] 4. The various components in the existing container valve are prone to the problem of poor sealing of the valve

[0008] 5. The pressure gas in the existing container valve is often directly connected to the fire-fighting equipment, so the gas pressure in the container valve is the same as the pressure gas in the fire-fighting equipment. Therefore, the solenoid valves, pressure switches and other equipment that need to be connected are often It needs to be able to withstand high pressure, which limits the scope of use of the container valve and increases the overall installation cost of fire fighting equipment
