Description
Technical field
The present invention relates to a kind of electric water heater safety valve, especially relevant with the end face seal electric water heater safety valve.
Background technique
Existing electric water heater safety valve part has adopted end face seal structure, and by seal with flat gasket, sealing effect is better when being connected with water heater for this structural safety valve.But let out copper embedded component that structure adopts a band boss and safety valve in it by being threaded, owing to let out the inserts complex manufacturing in the band boss copper, exist difficult quality guarantee, weight is heavier, the high deficiency of cost, in addition, copper insert and safety valve are by being threaded, its assembling mode inefficiency, and may exist hidden danger such as not in place are installed.
Summary of the invention
The purpose of this invention is to provide a kind of reliable in quality, in light weight, cost is low, lets out the snap-in end face seal electric water heater safety valve of inserts in easy for installation.
For achieving the above object, the present invention is achieved by the following technical solutions.In let out the snap-in end face seal electric water heater safety valve of inserts, comprise valve body, handle, the body that leaks, in let out body and flat gasket, in let out body and comprise valve rod, band filter screen deck, water inlet spring, stage clip, spring seat, reverse gasket seal, O shape circle and in let out inserts, in let out inserts and comprise reverse sealing seat and angle, angle is located at reverse sealing seat below, oppositely sealing seat is provided with O shape ring recess, and oppositely sealing seat matches with the valve body inner ring, and O shape circle is located in the O shape ring recess, oppositely be provided with groove below the sealing seat in valve body, angle snaps in the groove.
Let out the snap-in end face seal electric water heater safety valve of inserts in described, the quantity of its angle is 2-100, and is uniformly distributed in reverse sealing seat below.
Let out the snap-in end face seal electric water heater safety valve of inserts in described, also comprise circlip, circlip snaps in the groove, and is positioned at the angle below.
Let out the snap-in end face seal electric water heater safety valve of inserts in described, reverse sealing seat and the angle let out in it on inserts are integral type, and its material adopts engineering plastics.
The present invention compared with prior art has the following advantages: (one) is compact structure, reasonable.Use engineering plastics Alloy instead of Copper material simultaneously, manufacture cost can reduce greatly, and stability and Economy have both; (2) be to adopt end face seal structure, easy for installation, good seal; (3) be to adopt embedded component structure and valve body to assemble, install very conveniently that efficient is enhanced about more than once; (4) be to adopt band screen card stand structure, filter the impurity in the water source to greatest extent, prolong the working life of water heater greatly; (5) be the closed electrical water heater of this electric water heater safety valve applicable to any model; (6) be in the angle lower grooves, to snap in circlip, play a supportive role, let out inserts in guaranteeing and can not improve reliability of products because of high pressure is rushed out valve body.
