Abstract
The utility model provides an air flow balance valve which comprises an upper valve body. The upper valve body is provided with a starting air inlet connector and a driven bottle connector, a fodder chopper is arranged inside the upper valve body, a spring is sleeved on the fodder chopper, the upper end of the spring abuts against a piston, the other end of the fodder chopper is arranged inside a lower valve body. A locking nut and a sealing membrane capable of being penetrated through by the fodder chopper are arranged inside the lower valve body, and the locking nut and the sealing membrane are arranged at the tail end of the fodder chopper. The structure of the air flow balance valve is optimized, the balanced distribution of air can be achieved, the operation is reliable and safe, cost is saved, and using is convenient.
Description
Technical field
What this practical product related to is a kind of extinction using gas combined distribution system valve technology, and what be specifically related to is a kind of gas flow equilibrium valve.
Background technique
Adopting nitrogen to start bottle in Chinese extinction using gas combined distribution system now controls and distributes, its working method nitrogen is opened then agent application of extinguishing agent storage bottle bottle valve as starting gas, this type systematic starts bottle to be separated separately with the storage bottle, need to increase the startup bottle and start bottle stand and pipe fitting, increase cost and be not easy to Installation and Debugging.
The model utility content
Technical problem to be solved in the utility model is, overcomes in the prior art to have problems, and a kind of gas flow equilibrium valve is provided.
In order to overcome the problems referred to above, technological scheme described in the utility model is such:
A kind of gas flow equilibrium valve, comprise a upper valve body, upper valve body has one and starts gas access joint and a driven bottle graft head, upper valve body inside is provided with a chopper, cover has spring on the chopper, and the spring upper end is against on the piston, and the other end of chopper is positioned at lower valve body, the seal membrane that lower valve inner is provided with locking nut and can be pierced through by chopper, locking nut and seal membrane are positioned at the end of chopper.
Be provided with O type circle on the described piston.
Beneficial effect, gas flow equilibrium valve described in the utility model, structure optimization can realize that gas equilibrium distributes, reliable safety is saved cost, and is easy to use.
Description of drawings
