Description
Technical field
The present invention relates to a kind of electric water heater safety valve, especially relevant with the filtering type electric water heater safety valve.
Background technique
Safety valve is the important composition annex of electric water heater, its major function be can releasing pressure automatically when hydraulic pressure is higher than this device setting pressure to guarantee safety, existing safety valve body cavity is not owing to there is filtrating equipment, move when replying after causing tap water pressure to be higher than the pressure release of safety valve pressure release setting pressure easily, leak on the sealing surface because of there being foreign matter to be retained in safety valve, cause safety valve to reply the back poor sealing and leak, because of rivetting for fixedly, existing safety valve leakage device can not unpick and wash structure again, safety valve is whole to be scrapped thereby make, influenced the normal safe handling of electric water heater, increased trouble to the user.In addition, existing electric water heater safety valve also often exists return flow wayward, and it is unstable to cause refluxing; And in let out in the device since flat gasket cooperate with valve rod unreasonable, deficiency such as hot water generation refluence when causing tap water to be cut off the water supply.
Summary of the invention
The purpose of this invention is to provide a kind of rational in infrastructure, good filtration effect, it is stable to reflux, hot water can not produce refluence when tap water was cut off the water supply, long service life, safe and reliable filtration type convex ring type electric water heater safety valve.
For achieving the above object, the present invention is achieved by the following technical solutions.Filtration type convex ring type electric water heater safety valve, comprise valve body, in let out device, the water inlet spring is regulated cap, leakage device, handle, filtrating equipment and protruding circle, the filtrating equipment upper end is connected with the adjusting cap, the filtrating equipment circumferential surface is provided with filter screen, the external diameter of the locating column on the spring seat is less than the internal diameter of filtrating equipment, and filtrating equipment lower end or spring seat surface of contact are provided with water intake, and filtrating equipment is facing to outer drain port, protruding circle is located at valve inleting water mouth place, valve body and protruding circle are an integral body, also are distributed with 1-50 boss at protruding circle edge, and filtrating equipment is made up of filter screen and rack, rack is by last ring, following ring, connecting sheet, connecting head and projection are formed, filter screen is located at ring and following interannular inside circumference, the connecting sheet connection is gone up and is encircled and encircle down, and connecting head is connected with last ring, and projection and following ring are connected, last ring is close to formula with the outer ring of ring down with valve body main cavity inwall and is cooperated the last ring and following top and the bottom that lays respectively at outer drain port of encircling.
Described filtration type convex ring type electric water heater safety valve, its filter screen is made by metal, plastics or fiber, and the size of its mesh is the 80-90 order.
Described filtration type convex ring type electric water heater safety valve is let out in it in device, is provided with 1-5 circle flange on the valve stem seal face that cooperates with flat gasket.
The present invention compared with prior art has the following advantages: (one) is that drain port is provided with filtrating equipment outside, guaranteed tap water pressure to be higher than safety valve pressure release setting pressure and moved when replying, not having again foreign matter to be retained in safety valve leaks on the sealing surface, stop the generation of water leakage phenomenon, improved Security and reliability that electric water heater uses greatly; (2) because the reasonable in design of filtrating equipment, and assemble easy, when improving life of product and reliability greatly, the cost increase but seldom, price performance is outstanding; (3) be that the valve rod bottom surface cooperates during with backflow, has controlled return flow owing to be provided with protruding circle and boss at the valve inleting water mouth, guaranteed to reflux steadily; (4) be to cooperate with flat gasket owing to being provided with flange at valve body inner valve stem sealing surface, increased reverse sealing, hot water can not produce refluence when tap water was cut off the water supply; (5) be that this filter apparatus configuration can be applied on any a electric water heater safety valve.
