Description

Novel direct-release type safety valve structure

Technical Field

The utility model relates to the technical field of safety valves, in particular to a novel direct-release type safety valve structure.

Background

The safety valve is a special valve which is in a normally closed state under the action of external force and prevents the medium pressure in the pipeline or the equipment from exceeding a specified value by discharging the medium to the outside of the system when the medium pressure in the equipment or the pipeline rises to exceed the specified value.

Although the existing water heater safety valve tends to be mature and stable in structural design, in the long-term use process of the water heater safety valve, different effects can be brought to design deviation in structural details, different influences are produced, for example, an adjusting cap in the safety valve is easy to fall off after long-term use to influence the pressure release effect, and a coating film arranged between a valve core and a main body is poor in sealing effect, and the like. Therefore, it is necessary to design a safety valve structure with a more stable structure and a better use effect.

The utility model aims to provide a novel direct-release type safety valve structure which is further optimized in structure, improves the use effect and prolongs the 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 novel directly let out relief valve structure, connects in the main part, by supreme involucra, rotation axis, spring, regulation cap, regulation axle bed, the knob that links to each other in proper order of down, the rotation axis runs through between involucra and knob, and on the rotation axis was located to the spring housing, regulation cap screwed joint was on the rotation axis, regulation axle bed one end spiro union in the main part, and the other end is pegged graft on the knob, the spiro union between regulation axle bed and the pressure regulating cap, the pressure regulating cap can be along the rotatory lift removal of regulation axle bed inner wall screw thread, the regulation axle bed is close to knob department and is equipped with the baffle ring, and baffle ring and regulation axle bed inner wall screw thread are prolonged to connect, and the baffle ring internal diameter is less than the regulation axle bed internal diameter of inner wall distribution screw thread.

Further, the leather film is arranged among the rotating shaft, the adjusting shaft seat and the main body, and a plurality of salient points are arranged on the contact surface of the leather film on the main body.

Further, a decorative cover is embedded on the outer surface of the knob.

Compared with the prior art, the utility model has the following advantages:

the novel direct-release type safety valve structure is further optimized, the use effect is improved, and the service life is prolonged. Specifically, a baffle ring is arranged at a limit position of the adjusting cap at the upper end of the movable range of the adjusting shaft seat, so that the influence of the pressure relief effect caused by the fact that the adjusting cap is separated from the movable range is avoided; the leather film structure is arranged between the rotating shaft and the main body, the contact surface between the leather film and the main body is changed from the original plane into a plurality of salient points which are added on the plane to share the pressure of the spring, so that the spring is prevented from being deformed and aged too early due to frequent use, and the spring has a more stable supporting effect.

Detailed Description

Embodiments of the present utility model are described in further detail below with reference to the accompanying drawings.

As shown in fig. 1 and 2, a novel direct-release safety valve structure is connected to a main body 1, and comprises a leather membrane 2, a rotating shaft 3, a spring 4, an adjusting cap 5, an adjusting shaft seat 6 and a knob 7 which are sequentially connected from bottom to top, wherein the rotating shaft 3 penetrates through the leather membrane 2 and the knob 7, the spring 4 is sleeved on the rotating shaft 3, the adjusting cap 5 is screwed on the rotating shaft 3, one end of the adjusting shaft seat 6 is screwed on the main body 1, the other end of the adjusting shaft seat is inserted on the knob 7, the adjusting shaft seat 6 is screwed with the pressure adjusting cap 5, and the pressure adjusting cap 5 can rotate, lift and move in a fixed range along the inner wall thread 61 of the adjusting shaft seat 6. Preferably, a baffle ring 62 is arranged at the position, close to the knob 7, of the adjusting shaft seat 6, the baffle ring 62 is connected with the inner wall threads 61 of the adjusting shaft seat 6 in a prolonged and integrated mode, and the inner diameter of the baffle ring 62 is smaller than that of the adjusting shaft seat 6 with the inner wall distributed threads 61; the setting of the baffle ring 62 can ensure that the adjusting cap 5 can not separate from the track of the thread 61 or even hang out along the thread 61 to fly the knob 7 when moving in the fixed range of the thread 61 on the inner wall of the adjusting shaft seat 6, thereby ensuring the safety and normal operation of pressure relief.

Specifically, the baffle ring 62 is disposed at the upper end of the inner wall thread 61 of the adjusting shaft seat 6 and is well connected with the inner wall thread 61 in a extending manner, and the baffle ring 62 may be shaped like a ring; the stopper ring 62 may be withdrawn at the inner wall screw 61 and reduce the inner diameter, thereby limiting the movable range of the adjustment cap 5.

As shown in fig. 3 and 4, the film 2 is disposed between the rotating shaft 3, the adjusting shaft seat 6 and the main body 1, and the film 2 covers the rotating shaft 3 and the adjusting shaft seat 6 to separate from the main body 1, so as to have a sealing function of preventing water flow from entering the valve body in a normally closed state of the safety valve, and also have a switching function when the safety valve needs to release pressure. Preferably, the contact surface of the film 2 on the main body 1 is provided with a plurality of protruding points 21, specifically, three protruding points 21 are uniformly distributed, and the film 2 is made of rubber material; the above structure of the coating film 2 has a more stable supporting effect when being pressed, is not easy to deform, prolongs the service life and also improves the working efficiency.

The outer surface of the knob 7 is embedded with a decorative cover 8, and the rotating shaft 3 is inserted into the decorative cover 8.

The utility model relates to a novel direct-release safety valve structure, which has the following working principle: when the safety valve is in a normally closed state, the leather membrane 2 coats the rotating shaft 3 close to the main body 1 and the adjusting shaft seat 6 plays a role in sealing; when the relief valve needs to release pressure, the water pressure pushes up the rotating shaft 3 covered by the film 2, water flows out from the water outlet, at the moment, the adjusting cap 5 can move in the range of the internal thread 61 of the adjusting shaft seat 6, the adjusting cap 5 can not suspend the thread 61 to push away the knob 7 due to the arrangement of the baffle ring 62, and meanwhile, the film 2 has more stable supporting function on the contact surface of the main body 1 due to the three protruding points 21, and the deformation of the film 2 is not easy to be caused.

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.
