Description

Technical Field

[0001] This utility model relates to the field of regulating valve technology, specifically a high-pressure constant discharge regulating valve. Background Technology

[0002] A regulating valve, also known as a control valve, is a final control element in the field of industrial automation process control. It receives control signals from the regulating control unit and uses power to change process parameters such as flow rate, pressure, temperature, and liquid level of the medium. It generally consists of an actuator and a valve.

[0003] In existing technologies, high-pressure constant discharge regulating valves generally lack an effective structure for accurately positioning the opening position of the sealing steel ball. They rely on a simple threaded rod for opening and closing control, which cannot accurately adjust the drainage flow according to actual production needs. This results in large fluctuations in drainage flow. Under long-term filtration, it is impossible to fix and position the threaded rod and the sealing ball. The threaded rod will cause the sealing ball to move downwards, making it difficult to fix it within the set range. In industrial production processes, excessive drainage can easily lead to resource waste and equipment failure, while insufficient drainage can affect the normal operation of the system, seriously restricting the continuity and stability of production.

[0004] In view of this, we have introduced a high-pressure constant discharge regulating valve. Utility Model Content

[0005] The purpose of this invention is to provide a high-pressure constant discharge regulating valve to solve the problems mentioned in the background art.

[0008] The drain outlet is located inside the conduit B, and a sealing steel ball is provided at the top of the drain outlet for sealing the drain outlet.

[0009] The concave frame is fixedly installed on the top of the conduit B. A pull rod is fixedly installed on the top of the sealing steel ball. A pull plate is installed on the top of the pull rod after passing through the conduit B and the concave frame. The pull plate is fixedly installed on the pull rod.

[0010] A positioning mechanism is provided on one side of the top of the conduit B. The cylinder of the positioning mechanism drives the moving plate and the plug plate to move so that one end of the plug plate is inserted into the inside of the pull rod to form a positioning.

[0011] Preferably, the positioning mechanism includes a side plate connected to the top side of the conduit B, the side plate being fixedly disposed with the conduit B, an inverted L-shaped frame connected to the top of the side plate, the inverted L-shaped frame being fixedly disposed with the side plate, a cavity being formed inside the inverted L-shaped frame, the cavity being integrally formed with the inverted L-shaped frame, a cylinder being connected inside the cavity, a movable plate being slidably disposed inside the cavity and located at the output end of the cylinder, a plug-in plate being connected to one side of the movable plate, the plug-in plate being fixedly disposed with the movable plate, and the plug-in plate being inserted into the interior of the pull rod.

[0012] Preferably, a spring is fitted onto the surface of the pull rod between the sealing steel ball and the guide tube B.

[0013] Preferably, the surface of the pull rod is connected to a positioning plate, the positioning plate and the pull rod are fixedly connected, and the surface of the positioning plate is connected to a scale line, the scale line and the positioning plate are integrally formed.

[0014] Preferably, the top of the concave frame is provided with a positioning block, which is used to observe the scale lines on the surface of the positioning plate and to fine-tune the sealing steel ball for easy observation.

[0015] Preferably, a limiting rod is connected inside the cavity, and the moving plate slides on the surface of the limiting rod. The limiting rod plays a guiding and limiting role, ensuring that the moving plate can only move in a straight line along the direction of the limiting rod.

[0017] Preferably, the surface of the sealing steel ball is provided with a sealing ring, which further enhances the sealing performance between the sealing steel ball and the drain outlet, and improves the working reliability of the valve.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] (1) The cylinder works in the cavity, and the cylinder pushes the moving plate to slide in the cavity. When the plug plate moves to the appropriate position, it is inserted into the plug slot of the pull rod, thereby fixing the pull rod in a specific position. This achieves the positioning of the opening position of the sealing steel ball, which can ensure that the drainage flow is stable within the set range and avoid the impact on production due to excessive or insufficient drainage.

[0020] (2) Through the combination design of positioning plate, scale line and positioning block, the operator is provided with intuitive information on the opening position of the sealing steel ball. The operator does not need to use additional complicated equipment. By observing the relative position of the positioning block and scale line, the operator can quickly understand the opening status of the drain outlet, which is convenient for timely adjustment, reduces the difficulty of operation and improves work efficiency.

[0021] (3) The sealing effect is effectively enhanced by the sealing ring on the surface of the sealing steel ball, which reduces the risk of liquid leakage. This not only improves the service life of the regulating valve itself, but also avoids environmental pollution and resource waste caused by leakage. It is especially suitable for handling high pressure and highly corrosive liquids, ensuring the safe and stable operation of the system. Attached Figure Description

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.

[0028] Please see Figure 1-4 This utility model provides a technical solution: a high-pressure constant discharge regulating valve, including: valve 2, a conduit A1 is provided on one side of the valve 2, and a conduit B3 is provided on the other side of the valve 2;

[0029] Drainage outlet 9 is located inside the conduit B3, and a sealing steel ball 8 is provided on the top of the drainage outlet 9;

[0030] A concave frame 10 is provided at the top of the conduit B3. A pull rod 7 is provided at the top of the sealing steel ball 8. A pull plate 5 is provided at the top of the pull rod 7 after passing through the conduit B3 and the concave frame 10.

[0031] A positioning mechanism is provided on one side of the top of the conduit B3. The cylinder 12 of the positioning mechanism drives the moving plate 14 and the plug plate 15 to move so that one end of the plug plate 15 is inserted into the pull rod 7 to form a position.

[0032] The positioning mechanism includes a side plate 22 connected to the top side of the conduit B3, which is fixedly disposed with respect to the conduit B3. An inverted L-shaped frame 4 is connected to the top of the side plate 22, which is fixedly disposed with respect to the side plate 22. A cavity 11 is opened inside the inverted L-shaped frame 4, which is integrally formed with respect to the inverted L-shaped frame 4. A cylinder 12 is connected inside the cavity 11. A moving plate 14 is slidably disposed inside the cavity 11 and is located at the output end of the cylinder 12. A plug-in plate 15 is connected to one side of the moving plate 14, which is fixedly disposed with respect to the moving plate 14. The plug-in plate 15 is inserted into the pull rod 7.

[0033] A spring 6 is fitted onto the surface of the pull rod 7 between the sealing steel ball 8 and the guide tube B3.

[0034] The surface of the pull rod 7 is connected to a positioning plate 21, which is fixedly set with the pull rod 7. The surface of the positioning plate 21 is connected to a scale line 20, which is integrally formed with the positioning plate 21.

[0035] The top of the concave frame 10 is provided with a positioning block 19, which is used to observe the scale line 20 on the surface of the positioning plate 21 and to fine-tune the sealing steel ball 8 for easy observation.

[0036] The cavity 11 is connected to a limiting rod 13, and the moving plate 14 slides on the surface of the limiting rod 13. The limiting rod 13 serves as a guide and limiter, ensuring that the moving plate 14 can only move in a straight line along the direction of the limiting rod 13.

[0037] The inner side of the pull rod 7 is provided with equally spaced insertion slots 17 for inserting the insertion plate 15. The insertion slots 17 and the pull rod 7 are integrally formed.

[0038] The surface of the sealing steel ball 8 is provided with a sealing ring 16, which further enhances the sealing performance between the sealing steel ball 8 and the drain outlet 9 and improves the working reliability of the valve 2.

[0039] Specifically, in use, in the high-pressure constant discharge regulating valve, the drain port 9 is located inside the conduit B3. The sealing steel ball 8 at its top plays a key role in sealing and drain control. The spring 6 is in a naturally extended state. Under the action of the spring 6, the sealing steel ball 8 is tightly attached to the drain port 9, preventing liquid from being discharged from the drain port 9 and ensuring the system's sealing performance. If it is necessary to discharge liquid or air, the cylinder 12 drives the moving plate 14 and the plug plate 15 to move, allowing the plug plate 15 to enter the cavity 11. At this time, the pull plate 5 is pulled, causing the pull plate 5 to move the pull rod 7 upward. The pull rod 7 will move the sealing steel ball 8 upward together, allowing the sealing steel ball 8 and the sealing ring 16 to release the seal on the drain port 9, thereby allowing liquid or air to be discharged.

[0040] Next, cylinder 12 is activated. Cylinder 12 works in cavity 11, and its output end pushes the moving plate 14 to slide in cavity 11. Since the moving plate 14 slides on the surface of the limiting rod 13, the limiting rod 13 plays a guiding and limiting role, ensuring that the moving plate 14 can only move in a straight line along the direction of the limiting rod 13. The plug plate 15 connected to one side of the moving plate 14 will move synchronously with the moving plate 14. The pull rod 7 has plug slots 17 evenly spaced on one side inside. When the plug plate 15 moves to the appropriate position, it is inserted into the plug slot 17 of the pull rod 7, thereby fixing the pull rod 7 in a specific position, which realizes the positioning of the opening position of the sealing steel ball 8.

[0041] When fine-tuning the sealing steel ball 8 is required, a positioning plate 21 is connected to the surface of the pull rod 7 to facilitate the operator's understanding of the opening position of the sealing steel ball 8. The surface of the positioning plate 21 is provided with scale lines 20. The positioning block 19 at the top of the concave frame 10 is used to observe the scale lines 20 on the surface of the positioning plate 21. By observing the relative position of the positioning block 19 and the scale lines 20, the operator can intuitively obtain the opening degree information of the sealing steel ball 8, and then adjust the opening position of the sealing steel ball 8 according to actual needs through the positioning mechanism.

[0042] The sealing steel ball 8 is provided with a sealing ring 16, which further enhances the sealing performance between the sealing steel ball 8 and the drain port 9. When the sealing steel ball 8 and the drain port 9 are in contact, the sealing ring 16 fills the tiny gaps that may exist between them, effectively preventing liquid leakage, ensuring the sealing performance of the system in the non-drainage state, and improving the working reliability of the valve 2.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
