Abstract

The utility model relates to a pneumatic auxiliary component, particularly to a quick exhaust valve. The quick exhaust valve comprises a valve body, an exhaust port and an elastic piston, wherein the valve body is a rectangular body; an exhaust port hole and an intake port communicated with each other are disposed on the top end surfaces of the valve body respectively; a gas outlet hole communicated with the exhaust port hole is disposed on the upper end surface of the valve body; the elastic piston is disposed in the exhaust port hole on the valve body; and an exhaust port is screwed to the exhaust port hole on the valve body. The quick exhaust valve disclosed by the utility model has the following advantages that: the time used for emptying air in an execution mechanism is reduced, and air exhaust is started when the pressure of a gas source is reduced to be less than the pressure of the gas outlet, thus realizing the corresponding of fault in the first place; moreover, work is automatically recovered when the pressure of the gas source is recovered to a workable pressure, thus reducing manual operations and supervisions, saving manpower resource, as well as being simple in structure and low in cost.

Description

Rapid escape valve

Technical field

The utility model relates to a kind of air pressure auxiliary element, particularly a kind of rapid escape valve.

Background technique

At present; In some particular field in fields such as electric power, oil and chemical industry; A lot of operating modes all have bigger demand for pore actuator, and this just needs gas control actuator to improve constantly its Security, and often the automatic error protection venting gas appliance price of a cover is extremely expensive; Need be a kind of simple in structure, willing rapid exhaust.

Summary of the invention

In view of market demand, it is the purpose rapid escape valve with gas in the rapid emptying actuator under the source of the gas non-normal condition that the utility model provides a kind of.

The utility model is for realizing above-mentioned purpose; The technological scheme of being taked is: a kind of rapid escape valve is characterized in that: comprise valve body, relief opening, elastic piston, said valve body is a cuboid; On the two ends of valve body face, be respectively equipped with the exhaust oral pore, the suction port that communicate; Be provided with the air outlet hole that communicates with the exhaust oral pore in the valve body upper-end surface, said elastic piston places in the exhaust oral pore on the valve body, and said relief opening is screwed onto on the exhaust oral pore on the valve body.

The beneficial effect of the utility model is: reduce the used time of air in the emptying actuator;, source of the gas air pressure begins exhaust when being reduced to less than air outlet pressure; The very first time of having realized fault is corresponding, but and when bleed pressure returns to working pressure, resume work automatically, thereby reduced artificial operation supervision; Human resources have been saved, simple in structure and low in cost.

Description of drawings

Fig. 1 is the sectional side view of the utility model.

Fig. 2 is the outline drawing of the utility model.

Embodiment

Like Fig. 1, shown in 2, rapid escape valve comprises valve body 1, relief opening 2, elastic piston 3; Valve body 1 is a cuboid, on the both ends of the surface of valve body 1, is respectively equipped with the exhaust oral pore 1-1, the suction port 1-2 that communicate, is provided with the air outlet 1-3 that communicates with exhaust oral pore 1-1 in valve body 1 upper-end surface; At first; Valve body 1 is kept flat, elastic piston 3 is put into the exhaust oral pore 1-1 on the valve body 1, relief opening 2 is screwed onto on the exhaust oral pore 1-1 on the valve body 1 screws again.Elastic piston 3 adopts rubber or elastic metallic material.

During work; Source of the gas gas gets into rapid escape valve with elastic piston 3 distortion through suction port 1-2; Gas is passed through by the deformation place around the elastic piston 3; Get into actuator by air outlet 1-3, when source of the gas breaks down, when the air inlet gas pressure reduces less than actuator's internal air pressure; In the actuator gas through the air outlet the reverse entering rapid escape valve of 1-3 elastic piston 3 is pressed to the right elastic piston 3 is separated with relief opening 2, the gap of gas through elastic piston 3 and relief opening 2 is through relief opening 2 emptyings.

Claims
