Abstract
A safety valve with a pressure-relief device for electric water heaters includes a valve body, a handle, an internal releasing device, an external releasing device and a pressure-relief device. The pressure-relief device is disposed at the water inlet of the valve body and the casing of the pressure-relief device is integrated with the valve body.
Description
Technical field
The present invention relates to a kind of electric water heater safety valve, especially relevant with the electric water heater safety valve of band decompressor.
Background technique
Existing electric water heater safety valve does not have decompressor; frequently producing pressure release through regular meeting because variation in water pressure is higher than safety valve safety relief pressure leaks; light waste water resource then; influence health; heavy then can damage safety valve and shorten safety valve working life; because existing current decompressor is generally ring-like disk structure, exist complex structure again, cost height and effect of easing stress are undesirable to wait deficiency.
Summary of the invention
The purpose of this invention is to provide a kind of rational in infrastructurely, can prevent effectively that frequent pressure release from leaking the electric water heater safety valve of the band decompressor that effect of easing stress is desirable.
For achieving the above object, the present invention is achieved by the following technical solutions.The electric water heater safety valve of band decompressor comprises valve body, handle, in let out device, leakage device and decompressor, decompressor are located at valve inleting water mouth place, and the housing of decompressor and valve body are integral type, decompressor comprises housing, water intake, water outlet is regulated cap, Regulation spring, regulating piston, piston push rod, relief spring and plug, the water inlet is provided with the water inlet on the housing, the water outlet place is provided with osculum, Regulation spring, regulating piston, piston push rod and relief spring all are located in the housing inner chamber, regulate cap and plug and be located at housing two ends, piston push rod one end is a piston, and the other end is connected with regulating piston, regulating piston and piston all cooperate with the housing inner chamber, Regulation spring is located at and is regulated between cap and the regulating piston, and relief spring is located between plug and the piston, is provided with vent on piston push rod, vent one end is communicated with the water inlet, and the other end is communicated with pressure chamber between piston and the plug.
The electric water heater safety valve of described band decompressor is provided with O type groove on regulating piston and piston, on O type groove the O RunddichtringO is housed.
The electric water heater safety valve of described band decompressor, its housing inner chamber is a stepped ramp type.
The electric water heater safety valve of described band decompressor is provided with jump ring in the housing inner chamber one end plug outside, regulates the cap outside at the housing the other end and is provided with vinyl cover, is provided with the indication labeling in the vinyl cover end.
The present invention compared with prior art has the following advantages: (one) is provided with decompressor on electric water heater safety valve, can prevent effectively that the frequent pressure release of electric water heater safety valve from leaking, the conserve water resource, clean environment, the working life of improving electric water heater safety valve greatly; (2) be that this decompressor produces reaction thrust by piston structure, and then change the water inlet size that realize that the current adjusting reaches the decompression purpose, the mentality of designing novelty is ingenious, has overcome the deficiency of traditional current decompressor; (3) be all to be provided with the O RunddichtringO on regulating piston and piston, the generation of having stopped water leakage phenomenon has improved Security and the reliability used greatly; (4) be because the reasonable in design of current decompressor, and assemble easyly that the product price ratio further improves.
