The utility model has the advantages that: the structure design is reasonable, the manufacturing process is simplified, the anti-rot and anti-corrosion effects are realized, the durability is realized, the sealing performance is ensured, and the water leakage is avoided.
Description
Technical Field
The utility model relates to a relief valve technical field, concretely relates to novel 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. As shown in fig. 1 is the relief valve structure sketch map that uses at present, the relief valve includes the valve body and the pressure release body, sets up 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 and the 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, manufacturing process simplify, anticorrosion.
In order to achieve the above purpose, the utility model discloses a following technical scheme realizes:
the utility model provides a novel anticorrosion electric water heater relief valve, includes the valve body and the pressure release body, is equipped with the pull rod in the pressure release body, and the spring is established to the cover on the pull rod, the pull rod top is equipped with the supporting seat, sets up the adapter sleeve between pull rod top and the supporting seat, is equipped with the integrative cap and the gasket of pressing of rubber coating between the valve body and the pressure release body, and the supporting seat offsets with the integrative cap and the gasket of pressing of rubber coating.
Further, the connecting sleeve is in threaded connection with the supporting seat.
Furthermore, the connecting sleeve is made of metal materials or plastics, and the supporting seat is made of stainless steel materials.
Furthermore, the rubber-coated integrated pressure cap and gasket are provided with a sealing ring at the connecting end of the valve body and the pressure relief body.
Compared with the prior art, the utility model, have following advantage:
the utility model relates to a novel anticorrosion electric water heater relief valve, structural design is reasonable, and the manufacturing process is simplified, prevents rotten anticorrosion, and durable guarantees the leakproofness, avoids leaking.

Fig. 2 is a schematic structural diagram of the safety valve of the novel 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.
A novel anti-corrosion electric water heater safety valve comprises a valve body 1 and a pressure relief body 2. A pull rod 8 is arranged in the pressure relief body 2, a spring is sleeved on the pull rod 8, a supporting seat 6 is arranged at the top of the pull rod 8, a connecting sleeve 7 is arranged between the top of the pull rod 8 and the supporting seat 6, the top of the pull rod 8 is sleeved in the connecting sleeve 7 in a penetrating manner, and the connecting sleeve 7 is in threaded connection with the supporting seat 6; wherein, the connecting sleeve 7 can be made of metal material or plastic, and the supporting seat 6 is made of stainless steel material. Be equipped with the integrative pressure cap 3 of rubber coating and gasket 5 between valve body 1 and the pressure release body 2, the integrative pressure cap 3 of rubber coating and gasket 5 are equipped with sealing washer 4 at the link of valve body 1 and pressure release body 2, and supporting seat 6 offsets with integrative pressure cap 3 of rubber coating and gasket 5.
In order to achieve the anti-corrosion effect, the supporting seat is made of stainless steel materials. The design of the supporting seat needs to consider a connection and matching structure with the pull rod, and the original supporting seat is provided with a T-shaped groove to be conveniently matched with the pull rod; however, the stainless steel material has high hardness, the T-shaped groove is generally processed by a milling process, the efficiency is very low, and the cutter is easy to break. Therefore, the utility model discloses dividing original supporting seat structure into supporting seat 6 and adapter sleeve 7, supporting seat 6 and 7 spiro unions of adapter sleeve firstly embolia adapter sleeve 7 with pull rod 8, in 7 screw in supporting seats 6 with adapter sleeve again, just so avoided the milling flutes technology, improved process efficiency greatly.
The original sealing gasket adopts a pressing buckle or a pressing cap structure in the leakage body, and the sealing gasket is designed and exists independently, and has the risk of being punched out of a designed position under high temperature and high pressure, so that the leakage failure is caused. The utility model discloses a rubber coating technology: the pressing cap 3 is put into a rubber mold, a layer of high-temperature glue is coated on the surface of the pressing cap, then the glue material is put on the pressing cap, the mold is closed for vulcanization treatment, the glue layer on the surface is a gasket layer after the treatment, and the gasket layer and the pressing cap 3 can be firmly connected together into a whole and can be directly installed as a product. If the gasket is an independent gasket, the pressing cap needs to be sleeved in first, and then the pressing cap is screwed into the connecting end of the valve body and the pressure relief body, 2 steps are needed, and the process is complicated. Therefore, the pressure cap 3 and the gasket 5 which are integrally encapsulated are adopted, so that the risk that the gasket 5 is punched out by high pressure is avoided, and the installation efficiency is improved.
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.
