Description

Technical Field

[0001] This utility model belongs to the field of valve control technology, and specifically relates to a novel valve. Background Technology

[0002] In isotope-based waste treatment systems, the valves used are generally made of ceramic. Existing ceramic valves have gradually incorporated protective functions, such as overcurrent or overpressure protection devices, and anti-backflow protection devices. Some valves may also have both overcurrent / overpressure and anti-backflow protection devices simultaneously. These protective devices are assembled from individual components and installed one by one into the valve. However, due to the large number of components, improper installation can easily occur, causing the protective device to malfunction and posing a safety hazard. Furthermore, the overcurrent / overpressure and anti-backflow protection devices for various commonly used valve types differ, making the installation process cumbersome and complex. Utility Model Content

[0003] This utility model provides a novel valve to solve the technical problem that the overcurrent and overpressure protection devices and backflow prevention protection devices of various types of valves are different, which leads to a complicated and cumbersome process when installing different types of valves.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A novel valve includes a valve body with an inlet pipe connected to one end. The inlet pipe has a liquid passage space, and a support is provided within the liquid passage space. One end of the support is connected to the outside of the inlet pipe, and the other end is connected to the valve body. A sealing component movable along the length of the support is slidably connected inside the support via a sliding mechanism. Both ends of the support have through holes for gas and liquid to pass through, and both ends of the sealing component mate with these through holes. A return structure is provided between the sealing component and the through holes to allow the sealing component to return to its original position.

[0006] Preferably, the bracket includes an upper top plate and a lower top plate, which are connected by a plurality of limiting posts, which are evenly spaced in a ring; the sealing component is sleeved on the inner side of all the limiting posts; the sliding mechanism is disposed between the sealing component and a single limiting post; and the through hole is disposed in the middle of the upper top plate and the lower top plate.

[0007] Preferably, the sealing component includes an ellipsoidal slider, with sealing plugs at both the upper and lower ends of the ellipsoidal slider, and a sealing groove at the inner end of the through hole that seals with the conical surface of the sealing plug.

[0008] Preferably, the recovery structure includes a conical spring disposed between the sealing groove and the sealing plug, the conical tip of the conical spring being sleeved on the outside of the sealing plug and fixedly connected to the sealing plug, and the other end of the conical spring being fixedly connected to the bottom of the upper top plate.

[0009] Preferably, the sliding mechanism includes a plurality of sliding wheels disposed at the horizontal top of the ellipsoidal slider, the sliding wheels being vertically and equidistantly arranged on the outer surface of the ellipsoidal slider, and the outer side of the sliding wheels being provided with grooves that match the side of the limiting post.

[0010] Preferably, the valve body body is a shut-off valve body.

[0011] Preferably, the valve body is a gate valve body.

[0012] Preferably, the valve body is a ball valve body.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. When there is excessive flow or pressure of liquid, the present invention uses the reverse force of the recovery structure to make the sealing component close to the through hole of the valve body, preventing the excessive flow or pressure of liquid from directly entering the valve body and causing damage to the valve body; when liquid diversion occurs, the present invention uses the reverse force of the recovery structure to make the sealing component close to the through hole away from the valve body, thereby achieving an effective anti-diversion effect.

[0015] 2. This utility model directly integrates the two functions of overcurrent and overvoltage protection and backflow prevention protection, and can be installed into the corresponding valve in one go without multiple installations, making the installation process simple;

[0016] 3. This device can be installed and used on different valve bodies, making it highly versatile. Attached Figure Description

In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] The following is combined Figures 1-6 This utility model will be described in detail.

[0028] Example:

[0029] A novel valve, in some embodiments, such as Figures 1-6As shown, one end of the valve body is connected to an inlet pipe 1, and the inlet pipe 1 has a liquid passage space 2. The liquid passage space 2 has a support 3. One end of the support 3 is connected to the outside of the inlet pipe 1, and the other end is connected to the valve body. A sealing component that can move along the length of the support 3 is slidably connected inside the support 3 through a sliding mechanism. Both ends of the support 3 in the length direction are respectively provided with through holes 4 for gas and liquid to pass through. The two ends of the sealing component are engaged with the through holes 4. A return structure is provided between the sealing component and the through holes 4 to allow the sealing component to return to its original position.

[0030] In practical use, when overcurrent and overpressure liquid flows forward through the inlet pipe 1, the liquid overcomes the reverse force of the recovery structure, causing the sealing component to close the through hole 4 near the valve body, preventing the liquid from directly entering the valve body and causing damage. When liquid backflows and flows backward through the inlet pipe 1, the liquid overcomes the reverse force of the recovery structure, causing the sealing component to close the through hole 4 away from the valve body, thus achieving an effective anti-backflow effect. This device directly integrates overcurrent and overpressure protection and anti-backflow protection functions, and can be installed into the corresponding valve in one go, eliminating the need for multiple installations; the installation process is simple. This device can be installed and used on different valve bodies, demonstrating strong versatility.

[0031] In some embodiments, such as Figure 1 As shown, the bracket 3 includes an upper top plate 5 and a lower top plate 6, which are connected by a plurality of limiting posts 7, which are evenly spaced in a ring shape; the sealing component is sleeved on the inner side of all the limiting posts 7; the sliding mechanism is disposed between the sealing component and a single limiting post 7; and the through hole 4 is disposed in the middle of the upper top plate 5 and the lower top plate 6.

[0032] In practical use, a channel for liquid to pass through is formed between two adjacent limiting posts 7. The sealing component slides inside all the limiting posts 7 through the sliding mechanism, and closes the through hole 4 of the upper top plate 5 or the through hole 4 of the lower top plate 6 under different circumstances, thereby achieving different effects.

[0033] In some embodiments, such as Figures 1-2 As shown, the sealing component includes an ellipsoidal sliding member 8, with sealing plugs 9 at both the upper and lower ends of the ellipsoidal sliding member 8, and a sealing groove 10 at the inner end of the through hole 4 that seals with the conical surface of the sealing plug 9.

[0034] In practical use, the sealing plug 9 and the sealing groove 10 cooperate to seal the corresponding through hole 4.

[0035] In some embodiments, such as Figures 1-2 As shown, the recovery structure includes a conical spring 11 disposed between the sealing groove 10 and the sealing plug 9. The conical tip of the conical spring 11 is sleeved on the outside of the sealing plug 9 and fixedly connected to the sealing plug 9. The other end of the conical spring 11 is fixedly connected to the bottom of the upper top plate 5.

[0036] In practical use, the conical spring 11 is used to return the sealing component to its original position, so as to ensure that the valve body works under normal conditions. It is also worth mentioning that the elastic coefficient of the conical spring 11 close to the valve body corresponds to the overcurrent and overpressure standard of the valve body, while the elastic coefficient of the conical spring 11 far from the valve body corresponds to the pressure of the backflow liquid.

[0037] In some embodiments, such as Figures 1-4 As shown, the sliding mechanism includes a plurality of sliding wheels 12 disposed at the horizontal top of the ellipsoidal sliding member 8. The sliding wheels 12 are arranged vertically at equal intervals on the outer surface of the ellipsoidal sliding member 8, and the outer side of the sliding wheel 12 is provided with a groove 13 that matches the side of the limiting post 7.

[0038] In practical use, the ellipsoidal slider 8 is slidable by the cooperation between the sliding wheel 12 and the groove 13.

[0039] In some other embodiments, such as Figure 2 As shown, the main body of the valve body adopts the valve body 14 of a stop valve, thereby making the device suitable for the application scenario of a stop valve and used as a stop valve.

[0040] In some other embodiments, such as Figure 5 As shown, the valve body body adopts the gate valve body 15, thereby making the device suitable for the use of gate valves and used as a gate valve.

[0041] In some other embodiments, such as Figure 6 As shown, the valve body adopts a ball valve body 16, which makes the device suitable for ball valve application scenarios and can be used as a ball valve.

[0042] Specific operating principle:

[0043] When overcurrent and overpressure liquid flows forward through the inlet pipe 1, the liquid overcomes the reverse force of the recovery structure, causing the sealing component to close the through hole 4 near the valve body, preventing the liquid from directly entering the valve body and causing damage. Conversely, when liquid flows back through the inlet pipe 1, the liquid overcomes the reverse force of the recovery structure, causing the sealing component to close the through hole 4 away from the valve body, thus achieving effective anti-backflow protection. This device directly integrates overcurrent and overpressure protection and anti-backflow protection functions, allowing for one-time installation into the corresponding valve without multiple installations, simplifying the installation process. It can be installed and used on different valve bodies, demonstrating strong versatility.

[0044] The embodiments described above merely illustrate specific implementation methods of this application, and while the descriptions are detailed and specific, they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the technical solution of this application, and these modifications and improvements all fall within the scope of protection of this application.
