[0001] This utility model relates to the technical field of regulating valve seat removal equipment, specifically, to a regulating valve seat removal device. Background Technology

[0002] In industrial production and equipment maintenance involving control valves, valve seats sometimes need to be removed for repair, replacement, or inspection. Traditional removal methods often rely on manual disassembly using simple tools such as wrenches and pry bars. However, this manual approach has several drawbacks. Firstly, the installation location of control valve seats is usually quite narrow, limiting manual operation space and making it difficult to use tools, increasing the difficulty and time cost. Secondly, manual prying and tightening can easily damage the valve seat and surrounding connecting components, affecting the accuracy and subsequent service life of the control valve. Furthermore, relying solely on manual force makes it difficult to precisely control the removal force and direction, potentially leading to incomplete removal or damage to the valve seat, causing significant inconvenience to equipment maintenance.

[0003] How to achieve stable removal of the control valve seat is a question worth discussing. Summary of the Invention

[0004] This invention provides a valve seat removal device for regulating valves. The device uses an electric push rod to drive the clamping assembly to rise and fall, eliminating the need for manual prying, greatly simplifying the removal process, saving operation time, and improving work efficiency. Operators only need to control the extension and retraction of the electric push rod to easily move and remove the valve seat.

[0005] A valve seat removal device for a regulating valve includes a support plate, on which symmetrical electric push rods are fixedly connected. The telescopic rods of the symmetrical electric push rods are connected to a clamping assembly. The clamping assembly is used to clamp the valve seat of the regulating valve. The electric push rods drive the clamping assembly to rise, thereby realizing the upward movement and removal of the valve seat of the regulating valve.

[0006] As a further limitation of this technical solution, the clamping assembly includes a knob, a support rod, a connecting rod, a cross-shaped rod, an H-shaped rod, a screw, an L-shaped fixing rod, and a clamping plate. The upper ends of both ends of the support rod are respectively fixedly connected to the telescopic rod ends of the electric push rod. The upper middle part of the support rod is rotatably connected to the knob. The knob is threadedly connected to the screw. The lower end of the screw is fixedly connected to the center of one of the cross-shaped rods. The upper end of the screw passes through the center of the other cross-shaped rod. The upper cross-shaped rod is fixed to the lower center of the support rod. The ends of the two cross-shaped rods correspond one-to-one. The end of each cross-shaped rod is rotatably connected to one end of the connecting rod. The other ends of the two corresponding connecting rods are rotatably connected to both ends of the H-shaped rod. The H-shaped rod is fixed to one side of the vertical rod of the L-shaped fixing rod. The horizontal end of the L-shaped rod is fixedly connected to the clamping plate.

[0007] As a further limitation of this technical solution, the clamping plate is arc-shaped.

[0008] As a further limitation of this technical solution, it also includes a lifting assembly connected to the support plate for adjusting the height of the support plate, the electric push rod, and the clamping assembly. The lifting assembly includes a sleeve, a set screw, and a lifting rod. The lifting rod is slidably disposed inside the sleeve. The lifting rod is L-shaped, with its vertical section inserted into the sleeve. The horizontal section of the lifting rod is fixedly connected to the support plate. The set screw is threadedly connected to the upper part of one side of the sleeve, and the set screw can hold the lifting rod in place.

[0009] As a further limitation of this technical solution, the sleeve is fixed on the base.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are:

[0011] The electric push rod drives the clamping assembly to rise and fall, eliminating the need for manual prying, which greatly simplifies the removal process, saves operation time, and improves work efficiency. Operators only need to control the extension and retraction of the electric push rod to easily move the valve seat upward and remove it, and can operate flexibly even in narrow spaces.

[0012] The clamping assembly is ingeniously designed. Turning the knob can precisely control the movement of the screw, which in turn drives the connecting rod, H-shaped rod, etc., to open and close the clamping plate. It can stably and accurately clamp the regulating valve seat, avoiding the valve seat from slipping or being damaged due to unstable clamping.

[0013] Equipped with a lifting assembly, the overall height of the support plate, electric push rod, and clamping assembly can be easily adjusted through the cooperation of the sleeve, set screw, and lifting rod to accommodate the valve seat of the regulating valve at different height positions.

[0019] The following is in conjunction with the appendix Figures 1-3 The present invention will be further described in terms of the embodiments and implementation methods.

[0020] The specific embodiments of this utility model are as follows:

[0021] A valve seat removal device for a regulating valve includes a support plate 1. The support plate 1 is fixedly connected to symmetrical electric push rods 2. The telescopic rods of the symmetrical electric push rods 2 are connected to a clamping assembly 6. The clamping assembly 6 is used to clamp the valve seat of the regulating valve. The electric push rods 2 drive the clamping assembly 6 to rise, thereby realizing the upward movement and removal of the valve seat of the regulating valve.

[0022] The clamping assembly 6 includes a knob 601, a support rod 602, a connecting rod 603, a cross-shaped rod 604, an H-shaped rod 605, a screw 606, an L-shaped fixing rod 607, and a clamping plate 608. The upper ends of both ends of the support rod 602 are fixedly connected to the telescopic rod ends of the electric push rod 2. The upper middle part of the support rod 602 is rotatably connected to the knob 601. The knob 601 is threadedly connected to the screw 606. The lower end of the screw 606 is fixedly connected to the center of one of the cross-shaped rods 604. The upper end of the screw 606... Passing through the center of another cross-shaped rod 604, the upper cross-shaped rod 604 is fixed to the lower center of the support rod 602. The ends of the two cross-shaped rods 604 correspond one-to-one. The end of each cross-shaped rod 604 is rotatably connected to one end of the connecting rod 603. The other ends of the two corresponding connecting rods 603 are rotatably connected to the two ends of the H-shaped rod 605. The H-shaped rod 605 is fixed to one side of the vertical rod of the L-shaped fixing rod 607. The horizontal end of the L-shaped rod is fixedly connected to the clamping plate 608.

[0023] The clamping plate 608 is arc-shaped.

[0024] In this embodiment, the extension and retraction of the telescopic rod of the electric push rod 2 can drive the clamping assembly 6 to rise and fall, thereby lifting the regulating valve seat clamped by the clamping assembly 6.

[0025] In this embodiment, rotating the knob 601 can drive the screw 606, which is threadedly connected to it, to move. The screw 606 drives the lower cross-shaped rod 604 to move. The cross-shaped rod 604 drives the connecting rod 603 to swing. The connecting rod 603 drives the H-shaped rod 605 to move. The H-shaped rod 605 drives the L-shaped fixing rod 607 and the clamping plate 608 to move. When the screw 606 moves upward, it drives the cross-shaped rod 604 to move upward, so that the H-shaped rod 605 and the L-shaped fixing rod 607 move away from each other and the clamping plate 608 moves away from each other. When the screw 606 moves downward, the clamping plates 608 move closer to each other and clamp the regulating valve seat.

[0026] It also includes a lifting assembly 5, which is connected to the support plate 1 and is used to adjust the height of the support plate 1, the electric push rod 2 and the clamping assembly 6. The lifting assembly 5 includes a sleeve 501, a set screw 502 and a lifting rod 503. The lifting rod 503 is slidably disposed inside the sleeve 501. The lifting rod 503 is L-shaped. The vertical rod of the lifting rod 503 is inserted into the sleeve 501. The horizontal rod of the lifting rod 503 is fixedly connected to the support plate 1. The set screw 502 is threadedly connected to the upper part of one side of the sleeve 501. The set screw 502 can hold the lifting rod 503.

[0027] In this embodiment, the set screw 502 of the lifting component 5 is loosened, and the lifting rod 503 is no longer limited. Moving the lifting rod 503 can drive the clamping component 6 to rise and fall, thereby adjusting the height of the clamping component 6. After adjustment, the set screw 502 is tightened.

[0028] The sleeve 501 is fixed on the base 4.

[0029] The method of using this utility model is as follows:

[0030] In use, first adjust the initial height of the clamping assembly 6 using the lifting assembly 5 to ensure that the clamping assembly 6 is above the regulating valve seat. Adjust the clamping plate 608 of the clamping assembly 6 to the initial open state. Control the telescopic rod of the electric push rod 2 to descend to a suitable height so that the clamping plate 608 descends to a suitable height. Then, adjust the clamping plate 608 to clamp the regulating valve seat. Then, control the telescopic rod of the electric push rod 2 to move upward, causing the clamping assembly 6 to move upward, and lift out the regulating valve seat.

[0031] Compared to traditional rough disassembly methods, the components of this device work together to remove the valve seat in a gentler and more precise manner. The clamping plate 608 is an arc-shaped plate, which effectively reduces damage such as collisions and scratches to the valve seat and surrounding components, thus ensuring the original performance of the regulating valve.

[0032] The above description is only one embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
