Description

Technical Field

[0001] This utility model relates to the field of pressure reducing valve technology, specifically a stainless steel tilting pressure reducing valve with an anti-loosening structure. Background Technology

[0002] A pressure reducing valve is a type of valve that reduces the inlet pressure to a desired outlet pressure by adjusting the pressure, and automatically maintains a stable outlet pressure by relying on the energy of the medium itself. An inclined pressure reducing valve is a device that achieves automatic water pressure regulation through the inclined design of the upper part of the valve body. It mainly consists of a valve body, a valve core assembly, and a valve cover.

[0003] For example, the inclined pressure reducing valve provided by Chinese utility model patent with publication number CN202402739U consists of a valve body, a valve core assembly, and a valve cover. The upper part of the valve body is inclined towards the water inlet end. The valve core assembly consists of a sealing pressure ring, a pressure spring, an adjusting pressure cover, a pressure regulating drive rod, a spring seat cup, a positioning nut, a fine-tuning telescopic sealing cup, a valve core body, a valve core connecting screw, a sealing rubber ring, a support rod, a gasket, a sealing gasket, a valve top, and a locking nut. It is locked by the valve core connecting screw with the positioning nut and the locking nut. The upper part of the valve core body is a pressure regulating chamber, and the lower part is a flow control chamber. Pressure regulation is implemented through the pressure regulating chamber and the flow control chamber. This utility model is scientifically designed, rationally structured, reliable in performance, compact in components, low in cost, simple to manufacture, easy to produce, impact-resistant, aging-resistant, non-toxic, corrosion-resistant, and oxidation-resistant. It utilizes the water pressure of the water source to achieve automatic water pressure regulation and is widely used in agricultural water-saving irrigation, especially in sloping and mountainous areas, saving a lot of investment. It can also be used in fields where water pressure requirements are strict for water delivery.

[0004] To improve the corrosion resistance of tilt-type pressure reducing valves, stainless steel is usually selected for their construction. However, existing tilt-type pressure reducing valves are mostly connected to pipelines via flange or threaded connections. As water flows through the pipeline, various factors can cause vibrations, which can easily lead to loosening at the connection between the tilt-type pressure reducing valve and the pipeline, thus affecting the valve's performance. Utility Model Content

[0005] The purpose of this invention is to provide a stainless steel tilting pressure reducing valve with an anti-loosening structure to solve the problems mentioned in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stainless steel tilting pressure reducing valve with an anti-loosening structure, comprising a tilting pressure reducing valve body and an anti-loosening component; the tilting pressure reducing valve body is made of stainless steel and includes a valve body, an inlet connector, and an outlet connector; the inlet connector and the outlet connector are symmetrically fixed on both sides of the valve body; the anti-loosening component is arranged on the inlet connector and the outlet connector; the anti-loosening component includes a movable groove, a spring groove, a movable block, a connecting ring, and a return spring; both the inlet connector and the outlet connector have movable grooves; the movable grooves have spring grooves; the movable block slides through the movable groove; the connecting ring slides in the spring groove and is fixedly connected to the end of the movable block; the two ends of the return spring are fixedly connected to the inner wall of the spring groove and the connecting ring, respectively.

[0007] Preferably, the spring groove has an L-shaped cross-section, and the dimension of the spring groove on the side closer to the valve body is larger than the dimension of the spring groove on the side farther from the valve body.

[0008] Preferably, the movable block includes a contact portion and a movable portion; the contact portion contacts the inner wall of the pipe, and the end of the movable portion is fixedly connected to a connecting ring.

[0009] Preferably, the cross-section of the contact portion is a right-angled trapezoidal structure, and the dimension of the contact portion on the side closer to the valve body is smaller than the dimension of the contact portion on the side farther from the valve body.

[0010] Preferably, the length of the protruding part of the contact portion is adapted to the distance between the connecting ring and the side of the spring groove inner wall.

[0012] Preferably, the sealing assembly includes a sealing groove and a sealing block; the sealing groove is formed on the side of the spring groove near the valve body; the sealing block is fixed to the connecting ring on the side near the valve body, and the sealing block is in contact with the sealing groove.

[0013] Preferably, both the sealing block and the sealing groove have serrated cross-sections, and the serrated edges of the sealing block and the sealing groove are staggered.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, by setting an anti-loosening component, ensures that when the inclined pressure reducing valve body is connected to the pipeline, the inner wall of the pipeline contacts and presses against the contact part, causing the movable block to slide in the movable groove and the connecting ring to slide in the spring groove. This causes the return spring to stretch under force until the sealing block contacts the inner wall of the sealing groove. At this time, the inner wall of the pipeline contacts the end face of the inlet or outlet connector. Due to the force generated by the stretching of the return spring, the contact part can abut against the inner wall of the pipeline, making the connection between the inlet or outlet connector and the pipeline more stable. This can prevent the inclined pressure reducing valve body from loosening at the connection with the pipeline due to water vibration, greatly improving the performance of the inclined pressure reducing valve body.

[0016] 2. This utility model, by setting a sealing groove and a sealing block, enables a seal between the connecting ring and the inner wall of the spring groove, so as to prevent water from seeping into the spring groove through the gap between the connecting ring and the spring groove during the flow of water in the pipeline and the inclined pressure reducing valve body, which would cause the water to corrode the return spring and cause damage. Setting the cross-section of both the sealing block and the sealing groove as a sawtooth structure can extend the contact area between the sealing block and the sealing groove and improve its sealing effect.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example: Figures 1-6As shown, this utility model provides a technical solution for a stainless steel tilting pressure reducing valve with an anti-loosening structure, including a tilting pressure reducing valve body 1 and an anti-loosening component 2; the tilting pressure reducing valve body 1 is made of stainless steel and includes a valve body 101, an inlet connector 102, and an outlet connector 103; the inlet connector 102 and the outlet connector 103 are symmetrically fixedly connected to both sides of the valve body 101; the anti-loosening component 2 is arranged on the inlet connector 102 and the outlet connector 103; if the pipeline and the inlet... The connector 102 or the outlet connector 103 uses a threaded connection. The selected pipe must have an internal thread groove that contacts the end face of the inlet connector 102 or the outlet connector 103. The anti-loosening component 2 includes a movable groove 201, a spring groove 202, a movable block 203, a connecting ring 204, and a return spring 205. Both the inlet connector 102 and the outlet connector 103 have a movable groove 201. The movable groove 201 has a spring groove 202. The movable block 203 slides through the movable groove 201. The connecting ring 204 is slidably disposed within the spring groove 202 and fixedly connected to the end of the movable block 203; the two ends of the return spring 205 are fixedly connected to the inner wall of the spring groove 202 and the connecting ring 204, respectively; the spring groove 202 has an L-shaped cross-section, and the dimension of the side of the spring groove 202 near the valve body 101 is larger than the dimension of the side of the spring groove 202 away from the valve body 101, so as to facilitate the simultaneous accommodation of the connecting ring 204 and the return spring 205; the movable block 203 includes a contact portion 2031 and a movable portion 2032; the contact portion 203... 1. The movable part 2032 is in contact with the inner wall of the pipe, and its end is fixedly connected to the connecting ring 204. The cross-section of the contact part 2031 is a right-angled trapezoidal structure, and the dimension of the contact part 2031 on the side closer to the valve body 101 is smaller than the dimension of the contact part 2031 on the side farther away from the valve body 101, so as to facilitate extending the contact area between the contact part 2031 and the inner wall of the movable groove 201 and reduce the amount of water seepage. The length of the extended part of the contact part 2031 is adapted to the distance between the connecting ring 204 and the inner wall of the spring groove 202.

[0027] This utility model, by setting an anti-loosening component 2, ensures that when the inclined pressure reducing valve body 1 is connected to the pipeline, the inner wall of the pipeline contacts and presses the contact part 2031, causing the movable block 203 to slide in the movable groove 201, the connecting ring 204 to slide in the spring groove 202, and the return spring 205 to stretch under force until the sealing block 302 contacts the inner wall of the sealing groove 301. At this time, the inner wall of the pipeline contacts the end face of the inlet connector 102 or the outlet connector 103, and the force generated by the stretching of the return spring 205 can make the contact part 2031 abut against the inner wall of the pipeline, making the connection between the inlet connector 102 or the outlet connector 103 and the pipeline more stable. This can prevent the inclined pressure reducing valve body 1 from loosening at the connection with the pipeline due to water vibration, greatly improving the performance of the inclined pressure reducing valve body 1.

[0028] As a preferred embodiment, a sealing component 3 is also included; the sealing component 3 is arranged in the spring groove 202; the sealing component 3 includes a sealing groove 301 and a sealing block 302; the spring groove 202 has a sealing groove 301 on the side near the valve body 101; the sealing block 302 is fixedly connected to the connecting ring 204 on the side near the valve body 101, and the sealing block 302 is in contact with the sealing groove 301; the cross-sections of the sealing block 302 and the sealing groove 301 are both sawtooth structures, and the sawtooth shapes of the sealing block 302 and the sealing groove 301 are staggered.

[0029] This invention provides a seal between the connecting ring 204 and the inner wall of the spring groove 202 by setting a sealing groove 301 and a sealing block 302. This prevents water from seeping into the spring groove 202 through the gap between the connecting ring 204 and the spring groove 202 during the flow of water in the pipeline and the inclined pressure reducing valve body 1, which would cause the water to corrode the return spring 205 and cause damage. The cross-sections of both the sealing block 302 and the sealing groove 301 are set as serrated structures, which can extend the contact area between the sealing block 302 and the sealing groove 301 and improve their sealing effect.

[0030] Working principle: When the inclined pressure reducing valve body 1 is connected to the pipeline, the inner wall of the pipeline will contact and press the contact part 2031, causing the movable block 203 to slide in the movable groove 201. This causes the connecting ring 204 to drive the sealing block 302 to slide in the spring groove 202, causing the return spring 205 to stretch until the sealing block 302 contacts the inner wall of the sealing groove 301. At this time, the inner wall of the pipeline contacts the end face of the inlet connector 102 or the outlet connector 103. Due to the force generated by the stretching of the return spring 205, the contact part 2031 can abut against the inner wall of the pipeline, making the connection between the inlet connector 102 or the outlet connector 103 and the pipeline more stable. This can prevent the inclined pressure reducing valve body 1 from loosening at the connection with the pipeline due to water vibration, greatly improving the performance of the inclined pressure reducing valve body 1.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
