Abstract
The utility model discloses a security valve of the electric water heater, which comprises a valve body, an adjustment cap, a feeding-water spring, a circumfluence body, a decompression shim, a spring base, a decompression spring, a press cap, a sealing seat, an O type ring, a draw rod and a crank. The circumfluence body is composed of a pressing spring, a location base, a flat gasket and a valve rod; the inner hole of the flat gasket is inserted in the convex platform of the location base; the flat gasket is arranged on the valve rod, and the concave slot of the valve clamped by the pressing spring to form integration; the upper part of the device is supported by the feeding-water spring, and is located by the adjustment cap. The utility model has advantages of no howling, no regorging of hot water when water is broken, sheet gasket being not dashed out, and no leaking at the crank; the device is a neo-generation security valve of the electric water heater.
Description
One, technical field
The utility model relates to a kind of safety valve, and is especially relevant with electric water heater safety valve.
Two, background technique
Safety valve is the main constituent elements in the electric water heater, and it mainly acts on is that inner container of electric water heater is shielded.Existing electric water heater safety valve exists that tap water reaches certain pressure and oppositely during pressure release, be easy to generate howling, hot water produced and flows backwards when tap water was cut off the water supply, during the reverse pressure release of inner bag high pressure, gasket seal is higher than setting pressure, deficiency such as handle place water leakage phenomenon during pressure release by recoil out valve body and tap water pressure of high pressure.
Three, summary of the invention
The purpose of this utility model provides a kind of no howling, hot water can not flow backwards when tap water was cut off the water supply, and gasket seal can not be rushed out and tap water pressure is higher than and sets pressure release pressure and the handle place can not leak during pressure release electric water heater safety valve when the inner bag high pressure sluiced.
For achieving the above object, technical solution of the present utility model is: electric water heater safety valve comprises valve body, regulates cap, the water inlet spring, reflux, pressure release pad, spring seat, the pressure release spring, pressure cap, sealing seat, O type circle, pull bar and handle, reflux is by positioning seat, flat gasket, and valve rod and stage clip are formed, the flat gasket endoporus is embedded in the positioning seat boss, be contained on the valve rod, block stem groove by stage clip and form one, its top is headed on by the water inlet spring, and by regulating the cap location, reflux is contained in the valve body main cavity.
Described electric water heater safety valve also comprises gasket seal, and sealing seat inner ring groove cooperates with O type circle, and the outer ring cooperates with gasket seal, is contained on the body sealed mouth that leaks.
Described electric water heater safety valve also is provided with 2-8 uniform positioning boss on the valve inleting water mouth.
Described electric water heater safety valve is provided with protruding circle on the valve stem seal face that cooperates with flat gasket.
The utility model electric water heater safety valve compared with prior art has the following advantages: (one) is compact structure, reasonable, and manufacture cost can reduce greatly, and stability and Economy have both; (2) be to be provided with boss at the main cavity water intake, the valve rod bottom surface cooperates during with backflow, the control return flow, and making refluxes under any pressure reduction can not produce howling; (3) be that main cavity inner valve stem sealing surface has a protruding circle to cooperate with flat gasket, changed traditional sealing means, increased reverse sealing greatly, when tap water was cut off the water supply, hot water can not flow backwards; (4) be that the flat gasket endoporus is embedded on the positioning seat boss, and head on that when making the water heater high pressure reflow, flat gasket can not gone out by water by valve rod; (5) be at the main body handle place of leaking a sealing seat to be housed, its inwall O type circle cooperates with pull bar, and the outer ring gasket seal cooperates with the body seal mouth that leaks, and when making tap water pressure be higher than the pressure release setting pressure, the handle place can not leak; (6) be the closed electrical water heater of this electric water heater safety valve, and assembling is simple, safe ready applicable to any model.
Four, description of drawings
Fig. 1 is the overall structure schematic representation of the utility model electric water heater safety valve.
Five, embodiment
