Description

Technical Field

[0001] This utility model relates to the field of regulating valve technology, specifically a sealing regulating valve with good sealing performance. Background Technology

[0002] A sealed control valve is a type of valve used to regulate parameters such as fluid flow, pressure, and temperature. Its key feature is its excellent sealing performance, effectively preventing fluid leakage. The valve body and seat of a sealed control valve are typically made of metal materials, such as stainless steel or carbon steel. The valve body contains an internal valve seat, the surface of which is precision-machined to ensure a good seal with the valve core. The valve core is the key component of the sealed control valve; it achieves sealing and regulation functions through its cooperation with the valve seat. The shape and structure of the valve core vary depending on the application; common types include spherical, conical, and flat shapes.

[0003] Most existing sealing control valves adopt an integrated design. When damage occurs inside the sealing control valve and repair is required, the process is cumbersome and increases the workload of operators. Utility Model Content

[0004] The purpose of this invention is to provide a sealing regulating valve with good sealing performance, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sealing regulating valve with good sealing performance, comprising a regulating valve body,

[0006] A connecting flange fixedly installed on the top of the regulating valve body;

[0007] And a connecting assembly located on the side of the regulating valve body;

[0008] The connection assembly includes a stabilizing mechanism disposed on the side of the regulating valve body;

[0009] A connecting mechanism is provided on the side of the regulating valve body.

[0010] Preferably, a second connecting flange is disposed in contact with the top of the first connecting flange, and a driving component is fixedly installed on the top of the second connecting flange.

[0011] Preferably, the stabilizing mechanism includes a base plate, the side wall of which is in contact with the side wall of the connecting flange, a limit plate is fixedly installed on the top of the base plate, a partition is fixedly installed on the side wall of the base plate, a screw is threaded onto the inner wall of the partition, and a nut is installed on the side wall of the screw.

[0012] Preferably, the sidewall of the nut is in contact with the sidewall of the partition, the inner wall of the nut is threadedly connected to the sidewall of the screw, and the bottom of the limiting plate is in contact with the top of the connecting flange.

[0013] Preferably, there are two base plates, both of which are equal in shape and size, and are symmetrically arranged with respect to the center plane of the regulating valve body in the left-right direction.

[0014] Preferably, the connecting mechanism includes a positioning rod and a pressure detector. The bottom of the positioning rod is fixedly connected to the top of the first connecting flange, and the side wall of the positioning rod is slidably connected to the inner wall of the second connecting flange with a positioning hole. A limit block is threadedly installed on the side wall of the positioning rod, and the bottom of the limit block is in contact with the top of the second connecting flange.

[0015] Preferably, one end of the pressure detector is fixedly connected to the side wall of the regulating valve body, and the inner wall of the pressure detector is connected to the interior of the regulating valve body.

[0016] This utility model provides a sealing regulating valve with good sealing performance. It has the following beneficial effects:

[0017] (1) This utility model allows the operator to slide the base plate from both sides of the connecting flange two. The base plate will drive the two partitions to fit together. At this time, one end of the partition penetrates the inner wall of the base plate. Then, the position of the nut is rotated, and the inner wall of the nut is threaded to one end of the screw, so that the position of the base plate can be quickly installed. Under the action of the limiting plate, the stability between the connecting flange one and the connecting flange two can be improved. When it is necessary to repair the internal parts of the regulating valve body, the position of the driving component can be quickly disassembled by operating in the opposite direction, which makes it easier for the operator to use the device. This solves the problem that most existing sealing regulating valves adopt an integrated design. When the internal parts of the sealing regulating valve are damaged and need to be repaired, the process is more complicated and increases the workload of the operator.

[0018] (2) When the operator uses the device, the regulating valve body needs to be assembled. First, the positioning rod is aligned with the connecting flange two, so that the positioning rod is inserted into the inner wall of the connecting flange two where the positioning hole is opened. Then the position of the limiting block can be rotated directly. Since the inner wall of the limiting block is threadedly connected to the side wall of the positioning rod, the positions of the connecting flange one and the connecting flange two can be quickly connected by rotating the position of the limiting block, and the regulating valve body and the driving component can be assembled.

[0024] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0025] Example 1: A preferred embodiment of the sealing regulating valve with good sealing performance provided by this utility model is as follows: Figures 1 to 4 As shown: A sealing regulating valve with good sealing performance, including a regulating valve body 1,

[0031] In this embodiment, the side wall of the nut 415 is in contact with the side wall of the partition 413, the inner wall of the nut 415 is threadedly connected to the side wall of the screw 414, and the bottom of the limiting plate 412 is in contact with the top of the connecting flange 3.

[0032] Furthermore, there are two base plates 411, both of which are equal in shape and size, and are symmetrically arranged with respect to the center face of the regulating valve body 1 in the left-right direction.

[0033] In the specific implementation process, the operator slides the base plate 411 from both sides of the connecting flange 2 3. The base plate 411 will drive the two partition plates 413 to fit together. At this time, one end of the partition plate 413 penetrates the inner wall of the base plate 411. Then, the position of the nut 415 is rotated. The inner wall of the nut 415 is threadedly connected to one end of the screw 414, so that the position of the base plate 411 can be quickly installed. Under the action of the limiting plate 412, the stability between the connecting flange 1 2 and the connecting flange 2 3 can be improved. When it is necessary to repair the internal parts of the regulating valve body 1, the position of the driving component 5 can be quickly disassembled by operating in the opposite direction.

[0034] Example 2: Based on Example 1, a preferred embodiment of the sealing regulating valve with good sealing performance provided by this utility model is as follows: Figures 1 to 4 As shown: The connecting mechanism 42 includes a positioning rod 421 and a pressure detector 422.

A limit block 423 is threadedly installed on the side wall of the positioning rod 421. The bottom of the limit block 423 is in contact with the top of the connecting flange 2 3.

[0035] In this embodiment, one end of the pressure detector 422 is fixedly connected to the side wall of the regulating valve body 1, and the inner wall of the pressure detector 422 is connected to the interior of the regulating valve body 1.

[0036] In the specific implementation process, when the operator uses the device, the regulating valve body 1 needs to be assembled. First, the positioning rod 421 is aligned with the connecting flange 2 3, so that the positioning rod 421 is inserted into the inner wall of the connecting flange 2 3 where the positioning hole is opened. Then, the position of the limiting block 423 can be directly rotated. Since the inner wall of the limiting block 423 is threadedly connected to the side wall of the positioning rod 421, the positions of the connecting flange 1 2 and the connecting flange 2 3 can be quickly connected by rotating the position of the limiting block 423, and the regulating valve body 1 and the driving component 5 can be further assembled.
