Description

Technical Field

[0001] This utility model belongs to the field of valve technology, and in particular relates to a valve with a replaceable valve seat. Background Technology

[0002] Valves are control components in fluid transport systems, possessing functions such as shut-off, regulation, flow guidance, backflow prevention, pressure stabilization, flow diversion, or overflow pressure relief. They are pressure elements used to control the flow of various types of fluids, including air, water, steam, various corrosive media, slurry, oil, liquid metals, and radioactive media.

[0003] Existing valves with replaceable seats are cumbersome to replace, increasing the time and cost of replacement and affecting normal valve operation. Furthermore, current seat installation methods rely on a single bolt and nut threaded connection, which is complex and prone to loosening or damage during disassembly and replacement, leading to unstable seat fixation and affecting sealing performance and fluid control. Therefore, we propose a valve with replaceable seats. Utility Model Content

[0004] The purpose of this invention is to provide a valve with a replaceable valve seat to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a valve with a replaceable valve seat, comprising:

[0006] The pipe body has connecting plates fixedly installed on both sides. A valve core is movably installed inside the pipe body. A connecting pipe is fixedly installed on the top surface of the pipe body and is connected to the inside of the pipe body. A first mounting plate is fixedly installed on the top surface of the connecting pipe. Multiple bolts are fixedly installed on the top surface of the first mounting plate. A second mounting plate is provided above the first mounting plate. The second mounting plate is sleeved with multiple bolts.

[0007] A rotating groove is formed on the bottom surface of the pipe body. A plug-in block is rotatably installed in the rotating groove. A sleeve block is provided above the plug-in block. The top surface of the sleeve block is fixedly connected to the bottom surface of the valve core.

[0008] The mounting assembly is disposed on the second mounting plate and is used for quick installation and removal of the valve core;

[0009] An adjustment component is disposed on the bottom surface of the pipe body and is used to adjust the rotation of the valve core.

[0010] In the above technical solution, the mounting assembly further includes multiple nuts, which are threaded onto corresponding bolts. A toothed ring is fixedly mounted on the outer side wall of each of the multiple nuts. A gear is rotatably mounted on the top surface of the second mounting plate. The gear meshes with the multiple toothed rings. A connecting rod is rotatably mounted inside the gear. A mounting block is fixedly mounted on the bottom end of the connecting rod. The bottom surface of the mounting block is rotatably connected to the top surface of the valve core.

[0011] In this technical solution, the operating ring handle drives the connecting rod to rotate. Since the connecting rod is rotated and installed inside the gear, and the gear meshes with the toothed rings on the outer walls of multiple nuts, the gear will rotate accordingly. After the gear rotates, it drives multiple nuts to rotate synchronously through the toothed rings, realizing the tightening or loosening of multiple nuts on the corresponding bolts. When the nut is loosened, the second mounting plate can be removed from the bolt, completing the disassembly of the valve seat. Conversely, by tightening the nut, the second mounting plate can be fixed on the first mounting plate, realizing the quick installation of the valve seat.

[0012] In the above technical solution, the adjusting component further includes a worm gear, which is fixedly installed at the bottom end of the plug-in block. A worm is provided between the two connecting discs. One end of the worm is rotatably connected to one side of one of the connecting discs. The worm meshes with the worm gear. A mounting bracket is fixedly installed on one side of the other connecting disc. A mounting seat is fixedly installed on one side of the mounting bracket. The other end of the worm is rotatably connected to the mounting seat.

[0013] In this technical solution, when the valve core rotates, the drive motor starts, and its output shaft drives the worm to rotate. Because the worm meshes with the worm wheel, and the worm wheel is fixedly installed at the bottom of the plug block, the rotation of the worm will drive the worm wheel, plug block and sleeve block to rotate, thereby realizing the rotation of the valve core in the pipe body. It is simple and practical.

[0014] In the above technical solution, the adjustment component further includes a drive motor, which is fixedly mounted on the other side of the mounting bracket. One end of the output shaft of the drive motor passes through the other side of the mounting bracket and is fixedly connected to the other end of the worm gear.

[0015] In this technical solution, by controlling the rotation direction and speed of the drive motor, the rotation angle of the valve core can be precisely adjusted, thereby controlling the valve opening and achieving the regulation of fluid flow in the pipeline.

[0016] Furthermore, in the above technical solution, the inner wall of the connecting disc and the surface of the valve core are both provided with an anti-rust coating.

[0017] This technical solution effectively prevents blockages inside the pipe due to internal rust, and is simple and practical.

[0018] In the above technical solution, a ring handle is further fixedly installed at the top end of the connecting rod.

[0019] In this technical solution, when it is necessary to install or remove the valve seat, the ring handle is operated to drive the connecting rod to rotate, which facilitates quick disassembly or installation and is simple and practical.

[0020] In the above technical solution, the plug-in block is further movably sleeved within the socket block.

[0021] In this technical solution, the valve core can be rotated by the cooperation of the plug block and the socket block, which is simple and practical.

[0022] The beneficial effects of this utility model are:

[0023] 1. This valve with replaceable valve seat allows for installation or removal of the valve seat by operating the ring handle to rotate the connecting rod. Since the connecting rod is mounted inside the gear, and the gear meshes with the toothed rings on the outer walls of multiple nuts, the gear rotates accordingly. After the gear rotates, it drives multiple nuts to rotate synchronously through the toothed rings, achieving the tightening or loosening of multiple nuts on the corresponding bolts. When the nuts are loosened, the second mounting plate can be removed from the bolt, completing the removal of the valve seat. Conversely, by tightening the nuts, the second mounting plate can be fixed on the first mounting plate, achieving quick installation of the valve seat.

[0024] 2. In this valve with replaceable seat, when the valve core is rotated, the drive motor starts, and its output shaft drives the worm to rotate. Because the worm meshes with the worm wheel, and the worm wheel is fixedly installed at the bottom of the plug block, the rotation of the worm will drive the worm wheel, plug block, and sleeve block to rotate, thereby realizing the rotation of the valve core in the pipe body. By controlling the rotation direction and speed of the drive motor, the rotation angle of the valve core can be precisely adjusted, thereby controlling the opening of the valve and realizing the regulation of the fluid flow in the pipeline.
