Description
Technical Field
The utility model relates to the technical field of safety valves, in particular to a safety valve refitted by a rubber seat.
Background
The safety valve as one kind of protector has the main operation principle of automatic pressure relief when the tap water pressure is higher than the rated pressure of the inner container of the electric water heater. The existing safety valve adopts the rubber seat with the gasket to tightly press and seal with the main body, and the gasket of the rubber seat and the main body frequently collide at the same position during pressure relief, so that the main body is easy to puncture and damage at the same position, and the service life of the safety valve is reduced.
Disclosure of Invention
The utility model aims to provide a safety valve with improved rubber seat, which is capable of guaranteeing quality, not easy to damage and prolonging service life.
In order to achieve the above purpose, the present utility model is realized by the following technical scheme:
the utility model provides a relief valve of rubber seat repacking, includes gasket, rubber seat, pull rod, pressure regulating cap, seal assembly, the handle that set gradually from interior to exterior in the valve body that links to each other with the main part and the valve body, the valve body downside is equipped with the delivery port, and the gasket is located the rubber seat top and is compressed tightly sealedly with the main part, and the rubber seat cup joints in the pull rod top, and the pull rod runs through in the valve body and cross-under spring, pressure regulating cap, seal assembly, handle in proper order, seal assembly seals in the valve body end, and the handle cup joints in the pull rod end, the oblique arris is laid to the rubber seat outer lane.
Compared with the prior art, the utility model has the following advantages:
compared with the original safety valve, the rubber seat modified safety valve has the advantages that the structure of the rubber seat is improved, the outer ring of the rubber seat is equidistantly distributed to be changed into the inclined edge from the original straight edge, and the inclined edge is distributed to ensure that water flows into the valve body along the arrangement direction of the inclined edge during pressure relief, so that the rubber seat is driven to rotate, the rubber seat with a gasket compresses a sealing main body under the reaction force of a spring after pressure relief is completed, and the gasket on the rubber seat and the main body collide at different positions during compressing and sealing due to the fact that the rubber seat rotates every time, so that the main body is not perforated and damaged due to frequent collision with the same position, the quality of the safety valve is ensured, and the service life of the safety valve is prolonged.

Description of the embodiments
Embodiments of the present utility model are described in further detail below with reference to the accompanying drawings.
As shown in fig. 1, the safety valve modified by the rubber seat comprises a valve body 2 connected with a main body 1, a gasket 21, a rubber seat 22, a pull rod 23, a pressure regulating cap 24, a sealing assembly 25 and a handle 26 which are sequentially arranged in the valve body 2 from inside to outside, a water outlet 27 is arranged at the lower side of the valve body 2, the gasket 21 is arranged at the top of the rubber seat 22 and tightly presses and seals with the main body 1, the rubber seat 22 is sleeved at the top of the pull rod 23, the pull rod 23 penetrates through the valve body 2 and sequentially penetrates through a spring 28, the pressure regulating cap 24, the sealing assembly 25 and the handle 26, the sealing assembly 25 is sealed at the tail end of the valve body 2, and the handle 26 is sleeved at the tail end of the pull rod 23. As shown in fig. 3 and 4, an inclined edge is arranged on the outer ring of the rubber seat 22; specifically, 5 inclined edges are equidistantly arranged on the outer ring of the rubber seat 22. The inclined edge is spirally raised, and the inclined edge and the datum line of the rubber seat 22 form an inclined angle of about 45 and ︒. The inclined edge is close to one end of the gasket 21 and is provided with a joint section, the inclination of the joint section is gentle, and the promotion of water flow to the inclined edge can be promoted.
As shown in fig. 5, during pressure relief, water flows from the main body 1 to the valve body 2, pushes the gasket 21 on the top of the rubber seat 22, and sequentially flows through the rubber seat 22, the pull rod 23 and the spring 28 sleeved on the pull rod 23, and finally flows out from the water outlet 17 on the lower side of the valve body 1. When the water flow passes through the rubber seat 22, the water flow pushes the inclined edge of the outer ring of the rubber seat 22 to enable the rubber seat 22 to rotate, so that the safety valve is guaranteed to be opened at different pressure release positions every time, the safety valve is further protected from being damaged, and the service life of the safety valve is prolonged.
The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the concept of the present utility model, and such modifications and adaptations are intended to be comprehended within the scope of the present utility model.
