Description
Technical field
The utility model belongs to spring-loaded safety valve.
Background technique
The safety valve of electric water heater has the interior pressure release part and the splenium branch that leaks.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 can regulate intake pressure and inner liner pressure then, when inner liner pressure surpasses certain value, a part of water in the inner bag is back to water pipe by interior pressure release passage, besides when water inlet is cut off the water supply, can guarantee to retain certain water yield in the inner bag, prevent that electric water heater from burning because of lack of water is empty.Its interior pressure releasing valve core of electric water heater Decompression valves in the prior art is provided with a undergauge groove, valve core upper sleeve has its top of a turriform spring to embed the undergauge groove, the drawback that this structure causes 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, and 4. turriform spring manufacture process control is relatively more difficult, and each is unequal to cause this spring pressure easily, can not regulate owing to pressure again, thus the uniformity of pressure release setting pressure in can not guaranteeing.A kind of electric water heater Decompression valves that No. 200320130263.1 utility model patents of the previous application of the utility model designer disclose, described these drawbacks have been overcome, but the pressure release valve seat opened and closed stability and the relevant sealing moved and awaits further raising in its deficiency was, when the water heater liner temperature is too high may cause in pressure releasing valve core when coming off, interior pressure releasing valve core can stop up intake pipe.No. 200520015189.8 utility model patents of the utility model designer application have then overcome these defectives; Can find afterwards, the Decompression valves fine finishing of this application and install cumbersomely, it is not high enough that water outlet connects the anti-fragility at outer tube place.
Summary of the invention
The utility model is solving existing electric water heater Decompression valves fine finishing and is installing cumbersome, water outlet connects the anti-not high problem of fragility in outer tube place, the electric water heater Decompression valves of plane sealing of the present utility model is provided for this reason, the processing of this Decompression valves is more convenient with installation, and it is not easy to crack that water outlet connects the outer tube place.
For addressing the above problem, the technical solution adopted in the utility model is pressure release valve seat and a back-up ring in being provided with in the intake tunnel of valve body (1), 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, be connected with its rear portion of pull bar on the outer pressure release spool and be with the adjusting gland, the pull bar outer end is connected with handle, its external wall of upper portion of pressure release valve seat has the step that inwardly contracts in the footpath in described, the water inlet of valve body is provided with colored shape through hole, its special way is that the exhalant canal place of valve body has step, and described back-up ring snap-together type back-up ring is matched with the step of described valve body.This back-up ring can be the step type back-up ring that is arranged with " O " RunddichtringO.
For preventing that the outer pressure release handle in the utility model from being drawn back by accident, can be connected with water in the drain opening of valve body and chew, water chew and handle between be associated with a fixing card.
Can be provided with a seal ring and be positioned at valve body exhalant canal place on described back-up ring, when water outlet was connected with outer tube, closed in the external mouth of pipe on this seal ring top, prevents to leak; And can reduce stress without sealing strip at spiral section when being connected, thereby can prevent the utility model water outlet place cracking with outer tube.
The utility model is because the exhalant canal place of valve body has step, described back-up ring snap-together type back-up ring is matched with the step of described valve body, and can on described back-up ring, be provided with a seal ring, prevent from when being connected with outer tube to leak, the spiral section of avoiding being connected with outer tube at water outlet adopts sealing strip to increase the phenomenon that stress causes cracking easily.The utility model changes water outlet place of original Decompression valves into end-Transverse plane sealing configuration by the lateral seal structure, makes the processing of valve more convenient with installation, and can prevent water outlet place cracking.
The drain opening of valve body is connected with water and chews, water chew and handle between be associated with the fixing the utility model of card, can prevent that then handle from being drawn back accidents such as causing scald by accident.
