Summary of the invention
In order to overcome the deficiency of existing function technology, the utility model provides a kind of delivery pressure stable, and low-pressure performance is good, a kind of gas clamping valve of good leak-proof effect in the safety pressure.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of gas clamping valve, comprise valve body, air inlet system, the controlling device of giving vent to anger, pressure stability device and safety installations, it is characterized in that described valve body is provided with the valve pocket of cavity body structure, soft diaphragm is installed in the valve pocket, diaphragm is supported by the diaphragm linkage mechanism and is covered by valve bonnet seal, and described diaphragm linkage mechanism is made up of the adjustable lever of diaphragm connecting rod that is fixedly installed in the diaphragm center and adjusting diaphragm connecting rod, and the adjustable lever sealing micelle that is used to seal valve in the valve pocket is installed on the adjustable lever; The spool of the described controlling device of giving vent to anger is a cone spool; Described safety installations is a flameproof apparatus, and is made up of explosion-proof push rod, explosion-proof push rod spring and explosion-proof rod seal micelle, and the fitting surface of explosion-proof rod seal micelle and valve body is a circular arc; Described adjustable lever is articulated in the valve pocket by the adjustable lever pin; Be provided with air vent with explosion-proof push rod cooperation place in the described valve body.
The beneficial effects of the utility model are: clamping valve of the present utility model is a kind of novel valve body that reduction valve and gas valve unite two into one that collects, and has solved the defective that reduction valve can not coexist and use in the kitchen range, is suitable on the portable clamping valve stove; The structural design of diaphragm connecting rod makes valve pocket have vast capacity, thereby makes the pressure return difference little, and delivery pressure is stable; The spool of the controlling device of giving vent to anger is a cone spool, owing to be that feel is smooth and easy by taper fit, the size that adjusts throughput that not only can be more humane can also solve once bumping against switch or firmly pushing away the flame-out worn-out disease of switch button slightly; The fitting surface of explosion-proof rod seal micelle and valve body is a circular arc, and valve body leak preventing effect in safety pressure is better; Be provided with air vent with explosion-proof push rod cooperation place in the valve body, valve body explosion-proof push rod when exceeding safety pressure ejects smooth and easy strong, thus safety and reliability; In sum, clamping valve structure low-pressure performance brilliance of the present utility model, combustion gas utilization ratio height, delivery pressure is stable, good leak-proof effect in the safety pressure, it is explosion-proof highly sensitive to exceed safety pressure, has catered to national energy conservation and environment protection, makes product have more hommization.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
