Abstract
The utility model relates to a water pressure linkage gas electromagnetic valve with sealed capsule, which is mainly composed of a valve body, a sliding shaft bar, an electromagnetic valve, a valve, an opening and closing spring, etc. A sealed capsule is arranged between the valve and the valve body; one end of the capsule is sheathed outside a sleeve pipe of the sliding shaft bar; the other end is in tight fit with one side of the valve. The electromagnetic valve is adopted; the shortage of prior art can be effectively eradicated; the shortage of the prior art can be overcome; the utility model has the advantages of small frictional force for the movement of the sliding shaft bar, saved power consumption, long service life, simple structure, safety, etc. The utility model is an ideal safe Electromagnetic valve for gas range gas electromagnetic valve.
Description
The utility model relates to a kind of control structure of gas water-heater, refers to a kind of solenoid valve of controlling burnt gas switch automatic on-off under hydraulic action in gas water-heater especially, specifically refers to a kind of hydraulic pressure linkage type gas electromagnetic valve with sealing capsule.
In the prior art, for preventing that combustion gas from entering the electromagnetism valve housing, on its sliding shaft rod, need put leak-stopping glue ring, this glue ring is in leak-stopping, make the frictional force between the sleeve pipe of sliding shaft rod and valve body strengthen, this surface friction drag has been offset a large amount of electromagnetic attractions, increased power consumption, especially at valve opening and meet the abnormal state electromagnetic force when disappearing, above-mentioned surface friction drag makes that valve is difficult to accomplish accurately and effectively to close, cause gas water-heater gas leakage, thereby have a strong impact on its Safety performance.
The purpose of this utility model just is to provide a kind of hydraulic pressure linkage type gas electromagnetic valve with sealing capsule, to pass through its simple and effective sealed against leakage capsule structure, eradicate prior art gas leakage effectively and used unsafe structure hidden danger, overcome the deficiencies in the prior art preferably, and have that the sliding shaft rod kinetic friction force is little, power consumptive province, long service life, advantage such as simple in structure and safe and reliable.
The purpose of this utility model realizes in the following manner: a kind of hydraulic pressure linkage type gas electromagnetic valve with sealing capsule, mainly form by valve body, sliding shaft rod, solenoid valve, valve, keying spring, housing and external terminal, it is characterized in that between valve and valve body, being provided with sealing capsule, this capsule one end is enclosed within the outside of sleeve that matches with sliding shaft rod and sliding sleeve, and by the end location that opens and closes spring, a side of the other end of capsule and valve forms and closely cooperates.
Adopt a kind of hydraulic pressure linkage type gas electromagnetic valve of the present utility model with sealing capsule, owing to adopted simple and effective sealed against leakage capsule structure, eradicate prior art gas leakage effectively and used unsafe structure hidden danger, the deficiencies in the prior art have been overcome preferably, and have that the sliding shaft rod kinetic friction force is little, power consumptive province, long service life, advantage such as simple in structure and safe and reliable, be a kind of very desirable safety type hydraulic pressure linkage type gas electromagnetic valve.
Description of drawings:
Accompanying drawing is a kind of example structure schematic representation of the present utility model.
Wherein: the 1-housing, the 2-solenoid valve, the 3-sliding shaft rod, the 4-sliding sleeve, the 5-sleeve pipe, the 6-valve body, 7-opens and closes spring, 8-valve, 9-sealing capsule, 10-external terminal, 11-valve pocket.
Below in conjunction with drawings and Examples the utility model is further described.
As shown in the figure, a kind of hydraulic pressure linkage type gas electromagnetic valve of the present utility model with sealing capsule, mainly form by valve body (6), sliding shaft rod (3), solenoid valve (2), valve (8), keying spring (7), housing (1) and external terminal (10), between valve (8) and valve body (6), be provided with sealing capsule (9), sealing capsule (9) one ends are enclosed within sleeve pipe (5) outside of matching with sliding shaft rod (3) and sliding sleeve (4), and by the end location that opens and closes spring (7), a side of the other end of sealing capsule (9) and valve (8) forms and closely cooperates.Above-mentioned sealing capsule (9) is one to have the elastic rubber tube of wrinkle, its part that is positioned at valve pocket (11) can fold with the motion of valve (8), its two ends in the movement process of valve (8), remain and valve (8) and valve body (1) between closely cooperate, thereby effectively realize the purpose of this utility model.
In use, sliding shaft rod promotes solenoid valve (solenoid valve is adhesive under "on" position at this moment), thereby drives sliding sleeve and valve under the water heating system hydraulic action, and blast tube is opened, and this moment, sealing capsule pass wall was compressed into rugosity; When hydraulic pressure disappears, under the effect that opens and closes spring, the valve return, sealing capsule also is stretched thereupon, and sealing capsule stops combustion gas to enter in the solenoid valve all the time in this process, thus the sealing of remaining valid.Simultaneously owing between sliding sleeve and sleeve pipe, saved leak-stopping glue ring, thereby reduce the surface friction drag between the two, improved its safety in utilization effectively, realized the purpose of this utility model.
Claims (2)
1, a kind of hydraulic pressure linkage type gas electromagnetic valve with sealing capsule, mainly form by valve body (6), sliding shaft rod (3), solenoid valve (2), valve (8), keying spring (7), housing (1) and external terminal (10), it is characterized in that between valve (8) and valve body (6), being provided with sealing capsule (9), this capsule one end is enclosed within sleeve pipe (5) outside of matching with sliding shaft rod (3) and sliding sleeve (4), and by the end location that opens and closes spring (7), the other end of sealing capsule (9) and a side of valve form and closely cooperate.
