Description

Technical Field

[0001] This utility model relates to the field of vacuum pendulum valve technology, and more specifically, to a heat-insulating coupling for a vacuum pendulum valve. Background Technology

[0002] Vacuum valves are components used in vacuum systems to change the direction of fluid flow, regulate the flow rate, and disconnect or connect pipelines. Among them, the vacuum pendulum valve, as a type of vacuum valve, occupies an important position in the vacuum valve field due to its advantages of small footprint and fast closing speed.

[0003] For existing mainstream pendulum valves, the valve closing action is achieved by a motor controlling a valve plate, causing the valve plate to swing within the valve body until it reaches the closed position, at which point the valve plate blocks the valve opening. During operation, many internal mechanisms of existing vacuum pendulum valves generate heat. If no measures are taken to prevent this heat from being blocked, it will affect the motor's operation. However, most existing pendulum valves have poor heat insulation. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a heat-insulating coupling for a vacuum swing valve.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A thermally insulated coupling for a vacuum pendulum valve is disclosed. The vacuum pendulum valve includes a hollow valve body with a valve port for fluid passage. A housing is disposed on one side of the valve body, and a valve plate is disposed inside the valve body. A motor and a transmission mechanism are disposed inside the housing, and the valve plate is detachably connected to the transmission mechanism. A partition is also disposed inside the housing between the motor and the transmission mechanism, and the thermally insulated coupling is rotatably disposed on the partition. The transmission mechanism and the output shaft of the motor are detachably connected through the thermally insulated coupling.

[0007] Furthermore, in this utility model, the aforementioned heat-insulating coupling includes a heat-insulating ring and a connecting ring that are interlocked with each other. The central axis of the heat-insulating ring and the central axis of the connecting ring are collinear. The heat-insulating ring is rotatably connected to the partition plate. The heat-insulating ring is drive-connected to the output shaft of the motor, and the connecting ring is drive-connected to the transmission mechanism.

[0008] Furthermore, in this utility model, the inner wall of the heat insulation ring is provided with at least one first groove, and a limiting pin is provided in the first groove, the limiting pin protruding from the inner wall of the heat insulation ring; the output shaft of the motor is provided with a connecting sleeve, the diameter of the connecting sleeve is the same as the inner diameter of the heat insulation ring, and the outer wall of the connecting sleeve is provided with a second groove that matches the limiting pin.

[0010] The beneficial effects of this utility model are:

Detailed Implementation

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Please see Figure 1-6 This utility model provides a technical solution:

[0021] A thermally insulated coupling for a vacuum pendulum valve is disclosed. The vacuum pendulum valve includes a hollow valve body 101 with a valve port 201 for fluid passage, and a valve plate 401 is placed inside the valve body 101. To facilitate the installation of a drive mechanism for driving the valve plate 401 to swing within the valve body 101, a housing 301 is installed on one side of the valve body 101. Specifically, the drive mechanism includes a motor 501 and a transmission mechanism 601, both installed within the housing 301, and the valve plate 401 is detachably connected to the transmission mechanism 601. A partition 701 is also installed inside the housing 301 between the motor 501 and the transmission mechanism 601. A thermally insulated coupling 801, which can insulate against heat, is rotatably mounted on the partition 701, and the output shaft of the transmission mechanism 601 is detachably connected to the output shaft of the motor 501 via the thermally insulated coupling 801.

[0022] The structure of the transmission mechanism 601 in this embodiment is referenced. Figure 3 and Figure 4 A connecting arm is installed on the outer wall of the valve plate 401. The end of the connecting arm away from the valve plate 401 has a slotted hole. The connecting arm is fixed to the bottom end of the transmission mechanism 601 by screws. The specific structural composition of the transmission mechanism 601 is not the focus of this application, and its structure is conventional; therefore, it will not be described in detail here. It only needs to be able to allow the valve plate 401 to swing within the valve body 101 under the drive of the motor 501. In other embodiments of this example, the transmission mechanism 601 can also use a simple transmission shaft.

[0023] Specifically, refer to Figure 5In this embodiment, the thermal insulation coupling 801 includes a thermal insulation ring 8011 and a connecting ring 8012 that are interlocked. The central axis of the thermal insulation ring 8011 and the central axis of the connecting ring 8012 are collinear. The thermal insulation ring 8011 is rotatably connected to the partition plate 701. The output shaft of the motor 501 is driven to the inner hole of the thermal insulation ring 8011, and one end of the transmission mechanism 601 is driven to the inner hole of the connecting ring 8012. When the motor 501 drives the thermal insulation coupling 801 to rotate, in order to increase the connection stability of the thermal insulation ring 8011 and the connecting ring 8012, in this embodiment, three protrusions 1001 are installed on the side wall of the thermal insulation ring 8011 near the connecting ring 8012. The side wall of the connecting ring 8012 near the thermal insulation ring 8011 has slots that correspond one-to-one with the three protrusions 1001. After the three protrusions 1001 are engaged with the three slots, the thermal insulation ring 8011 and the connecting ring 8012 are then fixed together with screws.

[0024] After the output shaft of motor 501 is connected to the heat insulation ring 8011, in order for the output shaft of motor 501 to drive the heat insulation coupling 801 to rotate synchronously, refer to... Figure 5 In this embodiment, the inner wall of the heat insulation ring 8011 has four first grooves, and a limiting pin 901 is installed in each of the four first grooves, with the limiting pin 901 protruding from the inner wall of the heat insulation ring 8011. The output shaft of the motor 501 is equipped with a connecting sleeve 902, the diameter of which is the same as the inner diameter of the heat insulation ring 8011. The outer wall of the connecting sleeve 902 has four second grooves (not shown in the figure) corresponding to the four limiting pins 901. When the connecting sleeve 902 is inserted into the inner hole of the heat insulation ring 8011, the connecting sleeve 902 rotates under the control of the motor 501, which drives the heat insulation coupling 801 to rotate. The heat insulation coupling 801 then drives the valve plate 401 to swing within the valve body 101 through the transmission mechanism 601 until the valve plate 401 swings to the closed position to block the valve port 201.

[0025] By installing a heat-insulating coupling 801 between the motor 501 and the transmission mechanism 601, the heat generated by the transmission mechanism 601 and other mechanisms during operation can be isolated, preventing this heat from being radiated to the motor 501 and thus not affecting the normal operation of the motor 501. Simultaneously, the partition 701 also serves to insulate against heat. Furthermore, the heat insulation ring 8011 must be made of heat-insulating material.

It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge.
