The utility model has the advantages that: the structure design is reasonable, the supporting seat and the sealing boss in the pressure relief body are made of stainless steel materials, and the pressure relief body is anti-rot and anti-corrosion and durable; the sealing gasket arranged between the valve body and the leakage body is buckled and fixed through the pressing cap, and tightly presses the sealing gasket with the sealing boss under the action of the spring, so that the sealing performance is ensured, and water leakage is avoided.
Description
Technical Field
The utility model relates to a relief valve technical field, concretely relates to anticorrosion electric water heater relief valve.
Background
The safety valve is an important component in the electric water heater and mainly used for protecting an inner container of the electric water heater. FIG. 1 is a schematic diagram of a safety valve used at present, which comprises a valve body and a valve seatThe pressure release body sets up seal gasket between valve body and the pressure release body, is equipped with supporting seat and sealed boss in the pressure release body, and the cover is established spring and supporting seat top cover and is established sealed boss on the supporting seat, thereby sealed boss joint seal gasket compresses tightly seal gasket and plays sealed effect under the effect of supporting seat spring. The existing valve body and the leakage body are made of brass (copper-zinc alloy) because the flowing water contains Cl-、S2-Ions are easy to react with zinc to damage copper-zinc alloy, and a sealing boss in the pressure relief body is easy to corrode under the action of continuous turbulent water, high temperature and high pressure; once the sealing boss is corroded, the safety valve loses the protection function of high-pressure automatic opening, so that water leakage of the water heater is caused, water consumption of a user is wasted, and the consequences of empty burning of a water tank of the water heater, fire caused by circuit failure and the like are seriously caused.
Disclosure of Invention
The utility model aims at providing an electric water heater relief valve that structural design is reasonable, sealed effectual, anticorrosion.
In order to achieve the above purpose, the utility model discloses a following technical scheme realizes:
the utility model provides an anticorrosion electric water heater relief valve, includes the valve body and the pressure release body, is equipped with seal gasket between the valve body and the pressure release body, is equipped with supporting seat and sealed boss in the pressure release body, and the cover is established the spring on the supporting seat and the supporting seat top cup joints sealed boss, and sealed boss offsets with seal gasket, is equipped with one between the valve body and the pressure release body and presses the cap, presses the cap to withhold fixed seal gasket and connects soon with valve body end inner wall screw thread.
Further, the supporting seat and the sealing boss in the pressure relief body are made of stainless steel materials.
Further, press the cap and seal gasket combination to become an organic whole structure.
Compared with the prior art, the utility model, have following advantage:
the utility model relates to an anti-corrosion electric water heater safety valve, which has reasonable structural design, and the supporting seat and the sealing boss in the pressure relief body are made of stainless steel materials, thereby being anti-rotten and anti-corrosion and durable; the sealing gasket arranged between the valve body and the leakage body is buckled and fixed through the pressing cap, and tightly presses the sealing gasket with the sealing boss under the action of the spring, so that the sealing performance is ensured, and water leakage is avoided.
Drawings
Fig. 1 is a schematic structural diagram of a safety valve of a prior art electric water heater.
Fig. 2 is a schematic structural diagram of the safety valve of the anti-corrosion electric water heater of the present invention.
Detailed Description
Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
As shown in fig. 2, an anticorrosion electric water heater safety valve, including the valve body 1 and the pressure release body 2, be equipped with seal gasket 3 between the valve body 1 and the pressure release body 2, be equipped with supporting seat 4 and sealed boss 5 in the pressure release body 2, the cover is established spring 6 and 4 tops of supporting seat and are cup jointed sealed boss 5 on the supporting seat 4, sealed boss 5 offsets with seal gasket 3, be equipped with one between the valve body 1 and the pressure release body 2 and press cap 7, press cap 7 withhold fixed seal gasket 3 and connect soon with 1 end inner wall screw thread of valve body. The pressing cap 7 is provided with an external thread, the corresponding position of the inner wall of the end of the valve body 1 is provided with an internal thread, and the pressing cap 7 is connected with the inner wall of the end of the valve body 1 in a screwing way.
The supporting seat 4 and the sealing boss 5 in the pressure relief body 2 are made of stainless steel materials. The sealing gasket 3 is made of rubber materials.
In the assembling process, the sealing gasket 3 is sleeved into the cap end of the pressing cap 7, and then the pressing cap 7 is screwed into the inner wall of the end of the valve body 1 for fastening, so that the sealing gasket 3 is fixed between the valve body 1 and the pressure relief body 2 by the pressing cap 7. A sealing boss 5 sleeved on the top of the supporting seat 4 in the pressure relief body 2 presses the sealing gasket 3 tightly under the action of a spring 6.
Preferably, can make up into an organic whole structure with pressing cap 7 and seal gasket 3, under the prerequisite of guaranteeing leakproofness and anticorrosion, the dismouting of being convenient for.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the concept of the present invention, and these improvements and decorations should also be considered as the protection scope of the present invention.
