Abstract
The invention relates to a relief valve for electric water heater. It includes valve body, internal relief valve seat, relainer ring, spring, internal relief valve core, external relief valve core, sealing washer, drawbar, regulating pressure cover regulating nut and screw rod, etc. Said invention also provides their connection mode and the concrete structure of the above-mentioned every component.
Description
Technical field
The invention belongs to spring-loaded safety valve.
Background technique
Safety valve on the electric water heater partly is made up of interior pressure release and two pressure releases of outer pressure release.Outer pressure release can guarantee that inner container of electric water heater pressure is not higher than secure setting, interior pressure release is the uniformity of the inner liner pressure of can regulate intake pressure then, when inner liner pressure surpasses certain value, make a part of water in the inner bag be back to water pipe by interior pressure release passage, besides when water inlet is cut off the water supply, it is a certain amount of to guarantee that water in the inner bag is retained in, and can not cause electric water heater to burn because of lack of water is empty.Its interior pressure releasing valve core (as shown in Figure 3) of electric water heater peace Decompression valves in the prior art is provided with a undergauge groove 30, valve core upper sleeve has a turriform spring 31 its tops to embed undergauge groove 30, the drawback that causes of this structure is: 1. the assembling of the assembly of valve own and dismounting are relatively more difficult, 2. difficult can the maintenance appears damaging in valve, 3. balance pressure can not be regulated, 4. the turriform spring is improper in each link control of manufacture process, each is unequal to be easy to cause this spring pressure, can not regulate owing to pressure again, thus the uniformity of pressure release setting pressure in can not guaranteeing.
Summary of the invention
The present invention will solve existing electric water heater Decompression valves because valve assembly assembling that the said structure defective is produced and dismounting are relatively more difficult, valve itself is difficult to be keeped in repair, balance pressure can not regulate and can not guarantee in problem such as pressure release setting pressure uniformity, electric water heater Decompression valves of the present invention is provided for this reason, its assembled of this Decompression valves and dismounting are than being easier to, maintenance and part exchanging are easy, and balance pressure is adjustable.
For addressing the above problem, the technical solution used in the present invention is pressure release valve seat and a back-up ring in being provided with in the intake tunnel of valve body, be provided with spring I between interior pressure release valve seat and the back-up ring, be equipped with interior pressure releasing valve core in the interior pressure release valve seat, be provided with outer pressure release spool in the outer pressure release passage of valve body and which is provided with gasket seal, be connected with its rear portion of pull bar on the outer pressure release spool and be with gland and the also female built-in cavity rear end portion of leaking that is positioned valve body of regulating, the pull bar outer end is connected with handle, its special way is: its top of pressure releasing valve core has spiro rod section in described, cover is furnished with an adjusting nut on this spiro rod section, is with on the interior pressure releasing valve core between the retaining platform of spring II in described adjusting nut and interior pressure release valve seat.
Can be provided with the section of extending upward on the pressure release valve seat in described, this extension is provided with opening slot, and described adjusting nut has radially outwardly projecting and is positioned at opening slot; And can in described, be provided with radial groove by the bottom surface of pressure releasing valve core, so can regulate interior pressure release pressure from the water intake direction of this valve in direct convenience ground.
The present invention is because its top of interior pressure releasing valve core has spiro rod section, cover is furnished with an adjusting nut on this spiro rod section, be with on the interior pressure releasing valve core between the retaining platform of spring II in described adjusting nut and interior pressure release valve seat, so the promptly interior pressure release pressure of the pressure of spring II can be regulated, need not to adopt the comparatively turriform spring assembly of difficulty of manufacturing, assembling, dismounting, make manufacturing, assembling and the dismounting of valve assembly easy, maintenance and part exchanging are also easy, and can guarantee the conformity of interior pressure release balance pressure; Interior pressure release valve seat is provided with the section of extending upward, and this extension is provided with opening slot, and adjusting nut has the present invention that radially outwardly projecting is positioned at opening slot, and the adjusting of pressure is more convenient, and stability is better.
