Abstract

A self-supporting adjusting valve for oxygen only comprises a controller, a connector, a left valve body, a right valve body, a valve seat and a valve core, wherein the valve core is a piston in the left valve body to separate the left valve body into a feedback pressure chamber and an opening pressure chamber, one end of the piston is provided with a spring in the feedback pressure chamber. The self-supporting adjusting valve for oxygen only is safe, reliable and durable.

Description

The special-purpose self-erecting type modulating valve of oxygen
Technical field:
The utility model relates to a kind of self-erecting type modulating valve, the special-purpose self-erecting type modulating valve of particularly a kind of oxygen.
Background technique:
At present, the self-erecting type modulating valve comprises pilot valve, joint, spring, left valve barrel, right valve barrel, valve seat, spool, because spool adopts diaphragm of rubber, belongs to Inflammable and easily breaks, poor stability and influence working life; Can not be as the modulating valve of oxygen special use.
Summary of the invention:
In order to solve the problem of above-mentioned existence, the utility model provides a kind of safe and reliable and special-purpose self-erecting type modulating valve of oxygen long service life.
Concrete technological scheme is as follows: the special-purpose self-erecting type modulating valve of a kind of oxygen comprises pilot valve, joint, left valve barrel, right valve barrel, valve seat, spool; Described spool is a piston, and piston is arranged in the left valve barrel, and it is feedback pressure chamber and cracking pressure chamber that left valve barrel is divided into two chambeies, and an end of piston is provided with spring, and spring is arranged in the feedback pressure chamber.
Compare with prior art, the utility model spool adopts metallic piston, can not burn in the course of the work, and Security is good and be difficult for breaking, growth working life; Be suitable for the oxygen special use.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is a structural representation of the present utility model.
Embodiment:
As shown in Figure 1, the special-purpose self-erecting type modulating valve of a kind of oxygen comprises pilot valve 1, joint 2, left valve barrel 7, right valve barrel 3, valve seat 9, spool 4; Described spool 4 is a piston, and piston is arranged in the left valve barrel 7, and it is feedback pressure chamber 6 and cracking pressure chamber 5 that left valve barrel 7 is divided into two chambeies, and an end of piston is provided with spring 8, and spring 8 is arranged in the feedback pressure chamber 6.
When downstream pressure reduced, the cracking pressure chamber entered gas and promotes piston to left movement, and valve port is opened, the pressure behind the increase valve, and when pressure reached adjusting pressure, the pressure in feedback pressure chamber and spring acting in conjunction promoted piston and move right, and valve port is closed.

Claims (1)

1, the special-purpose self-erecting type modulating valve of a kind of oxygen comprises pilot valve, joint, left valve barrel, right valve barrel, valve seat, spool; It is characterized in that: described spool is a piston, and piston is arranged in the left valve barrel, and it is feedback pressure chamber and cracking pressure chamber that left valve barrel is divided into two chambeies, and an end of piston is provided with spring, and spring is arranged in the feedback pressure chamber.
