[0002] The pressure reducing valve is an important component of rail vehicles, and its maintenance quality directly affects the performance of the EMU coupling, service life and operational safety. During the maintenance of the pressure reducing valve, the pressure reducing valve needs to be disassembled and assembled. After the pressure reducing valve is disassembled for maintenance, it needs to be packaged. When the internal spring is pressed, one person needs to fix the valve body while another person presses it.

If the personnel operate improperly, it will cause bolt thread slippage, press-fit failure and low construction efficiency. After the spring is pressed, the remaining parts of the pressure regulating valve need to be assembled and the torque is checked. Due to the irregularity of the valve body, it is difficult to position and easy to damage the valve body. Utility Model Content

DETAILED DESCRIPTION

[0031] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0032] like Figure 1 As shown, the embodiment of the utility model provides a pressure reducing valve disassembly and assembly device, comprising:

[0033] A base 100, on which a support rod 102 and a positioning assembly are disposed, and the positioning assembly is used to position the pressure reducing valve 132;

[0034] A sliding portion 104 is slidably disposed on the support rod 102;

[0035] A pressing portion, slidably mounted on the sliding portion 104;

[0036] The pull rod 106 is rotatably connected to the sliding part 104, and the clamping part is suitable for switching between a clamping position and a separation position relative to the sliding part 104 under the drive of the pull rod 106. In the clamping position, the clamping part is suitable for clamping the pressure reducing valve 132, and in the separation position, the clamping part is suitable for staying away from the pressure reducing valve 132.

[0037] According to the pressure reducing valve disassembly and assembly device provided by the embodiment of the utility model, the positioning assembly can ensure that the pressure reducing valve 132 is accurately positioned and fixed during the disassembly and assembly process. This helps to reduce the error during the disassembly and assembly process, improve the operating accuracy, and ensure the performance and stability of the pressure reducing valve 132 after disassembly and assembly. Through the design of the sliding part 104 and the pull rod 106, the operator can easily control the position of the pressing part. In the pressing position, the pressing part can effectively press the pressure reducing valve 132 to ensure that it will not move or misalign during the disassembly and assembly process; in the separation position, the pressing part can quickly move away from the pressure reducing valve 132, which is convenient for the removal or installation of the pressure reducing valve 132. Since the design of the sliding part 104 and the pressing part has a certain flexibility, the device can adapt to pressure reducing valves 132 of different sizes and models. This makes the device have strong versatility and can meet the disassembly and assembly requirements in different occasions. Through precise positioning and stable fixation, the device can reduce the risk of damage to the pressure reducing valve 132 during the disassembly and assembly process. At the same time, the operator can also operate more safely to avoid safety accidents caused by improper operation. The device simplifies the disassembly and assembly process of the pressure reducing valve 132, and reduces the operation steps and time. This can not only improve work efficiency, but also reduce labor costs and time costs.

[0038] Please continue to see Figure 1 The base 100 is the basic part of the disassembly and assembly device, and is provided with a support rod 102 and a positioning assembly. The support rod 102 provides support and guidance in the vertical direction to ensure that the sliding part 104 can move smoothly. The positioning assembly is used to accurately position the pressure reducing valve 132 to ensure that the pressure reducing valve 132 will not move or tilt during the disassembly and assembly process.

[0039] The sliding part 104 is slidably disposed on the support rod 102. By moving the sliding part 104 on the support rod 102, the height of the device can be adjusted to adapt to the pressure reducing valve 132 at different installation positions. The design of the sliding part 104 should ensure stability and smoothness during movement and have a certain load-bearing capacity.

[0040] The pressing part is mounted on the sliding part 104 and can slide relative to the sliding part 104. The main function of the pressing part is to press the pressure reducing valve 132 during the disassembly process to prevent it from moving or tilting during operation. The design of the pressing part should ensure that the force can be evenly applied during pressing to protect the pressure reducing valve 132 from damage.

[0041] The pull rod 106 is rotatably connected to the sliding part 104 and connected to the pressing part. By rotating the pull rod 106, the pressing part can be driven to switch between the pressing position and the separation position. In the pressing position, the pressing part tightly presses the pressure reducing valve 132; in the separation position, the pressing part is away from the pressure reducing valve 132, which is convenient for disassembly and assembly.

[0042] The device can be quickly adjusted to a suitable position by accurate positioning of the positioning assembly and rapid adjustment of the sliding portion 104. At the same time, the rotation operation of the pull rod 106 also makes the switching between the pressing portion and the separation position simple and fast, thereby greatly improving the disassembly and assembly efficiency of the pressure reducing valve 132.

[0043] During the disassembly and assembly process, the pressing part can firmly press the pressure reducing valve 132 to prevent it from moving or tilting during operation. This can not only protect the pressure reducing valve 132 from damage, but also ensure the safety of the operator.

[0044] The device can adapt to pressure reducing valves 132 of different heights and positions through the design of the sliding part 104. At the same time, the adjustability of the pressing part also enables the device to be applicable to pressure reducing valves 132 of different sizes and models. Therefore, the device has strong versatility and adaptability.

[0045] The design of the whole device is concise and clear, and the operator only needs to perform simple operations to complete the disassembly and assembly of the pressure reducing valve 132. This not only reduces the difficulty of operation, but also improves the accuracy and reliability of the operation.

[0046] According to an embodiment of the present invention, a mounting seat 108 is disposed on the sliding portion 104 , the pressing portion is slidably disposed on the mounting seat 108 , and the pull rod 106 is rotatably connected to the mounting seat 108 .

[0047] The base 100 serves as the foundation of the entire device, and a support rod 102 and a positioning assembly are provided on the base 100. The support rod 102 provides structural support in the vertical direction, and the positioning assembly is used to accurately position the pressure reducing valve 132 to ensure its stability during the disassembly and assembly process.

[0048] A mounting seat 108 is provided on the sliding portion 104, which provides a stable foundation for the installation of the clamping portion. The clamping portion is slidably disposed on the mounting seat 108. By sliding on the mounting seat 108, the clamping portion can be close to or away from the pressure reducing valve 132, thereby realizing the functions of clamping and separation. The design of the clamping portion should ensure that force can be evenly applied during clamping to prevent the pressure reducing valve 132 from sliding or rotating during the disassembly and assembly process. The pull rod 106 is rotatably connected to the mounting seat 108. By rotating the pull rod 106, the clamping portion can be driven to switch between a clamping position and a separation position relative to the mounting seat 108. In the clamping position, the clamping portion tightly presses the pressure reducing valve 132 to ensure its stability during the disassembly and assembly process; in the separation position, the clamping portion is away from the pressure reducing valve 132, thereby facilitating the disassembly and assembly operation.

[0049] By arranging a mounting seat 108 on the sliding part 104, the clamping part and the pull rod 106 are combined with the mounting seat 108, so that the structure of the whole device is more compact and occupies less space. The pull rod 106 is rotatably connected to the mounting seat 108, so that the operator only needs to rotate the pull rod 106 to switch the clamping part, and the operation is simpler and faster. The mounting seat 108 provides a stable installation foundation for the clamping part, so that the clamping part is more stable and reliable when clamping the pressure reducing valve 132, reducing the risk of damage caused by improper operation. The slidable design of the sliding part 104 on the support rod 102 enables the device to adapt to pressure reducing valves 132 of different heights and positions, thereby improving the versatility and adaptability of the device.

[0050] According to one embodiment of the utility model, the pressing portion comprises:

[0051] A pressure rod 110, the pressure rod 110 is slidably disposed on the mounting seat 108;

[0052] The pressing head 112 is disposed at one end of the pressing rod 110 facing the base 100 , and a avoiding groove 114 suitable for avoiding the connecting piece on the pressure reducing valve 132 is formed on the pressing head 112 .

[0053] The pressure rod 110 is the main bearing and transmission part of the pressing part, and is slidably disposed on the mounting seat 108. The pressure rod 110 is connected to the sliding part 104 through the mounting seat 108, and can adjust its position up and down with the movement of the sliding part 104. At the same time, the pressure rod 110 can also slide on the mounting seat 108 according to the operation of the operator, thereby changing the distance between it and the pressure reducing valve 132.

[0054] The clamping head 112 is arranged at one end of the pressure rod 110 facing the base 100, and is the part where the clamping part is in direct contact with the pressure reducing valve 132. The shape and size design of the clamping head 112 must match the shape and size of the pressure reducing valve 132 to ensure that force can be evenly applied during clamping to prevent the pressure reducing valve 132 from sliding or rotating during the disassembly process. In addition, avoidance grooves 114 are also provided on the clamping head 112. These avoidance grooves 114 are designed to avoid the connecting parts (such as bolts, nuts, etc.) on the pressure reducing valve 132 when the pressure reducing valve 132 is clamped, so as to avoid damage to the connecting parts or interference with the disassembly operation.

[0055] Through the cooperation of the pressure rod 110 and the clamping head 112, the pressure reducing valve 132 can be precisely clamped. The design of the clamping head 112 ensures that the force can be evenly applied to the pressure reducing valve 132, thereby improving the stability and safety of disassembly and assembly. The avoidance groove 114 design on the clamping head 112 allows the connector to be avoided when the pressure reducing valve 132 is clamped, thereby avoiding the difficulty or damage of disassembly and assembly caused by the interference of the connector. This design greatly improves the convenience and efficiency of disassembly and assembly. Since the clamping head 112 can be customized according to the shape and size of the pressure reducing valve 132, the device can adapt to pressure reducing valves 132 of different models and specifications, and has strong versatility and adaptability. By sliding the pressure rod 110 and rotating the pull rod 106, the operator can easily implement the clamping and separation operations of the clamping part without the use of additional tools or equipment, thereby reducing the difficulty and cost of operation.

[0056] According to an embodiment of the present invention, a connecting rod is provided on the mounting seat 108 , and an elastic recovery member 116 is provided between the connecting rod and the pressing rod 110 . The elastic recovery member 116 is suitable for driving the pressing part to switch from the pressing position to the separation position.

[0057] A connecting rod is provided on the mounting seat 108, and an elastic recovery member 116 is provided between the connecting rod and the pressing rod 110. This design enables the pressing part to automatically switch from the pressing position to the separation position without the need for external force, thereby improving the convenience and efficiency of operation.

[0058] Specifically, the connecting rod is used to install the elastic recovery member 116, and the elastic recovery member 116 is connected between the connecting rod and the pressure rod 110. When the operator needs to compress the pressure reducing valve 132, the pressure rod 110 can be slid relative to the mounting seat 108 through the pull rod 106, so that the pressing head 112 compresses the pressure reducing valve 132. In this process, the elastic recovery member 116 becomes longer and has the function of elastic recovery.

[0059] Once the pressure reducing valve 132 is disassembled and assembled, the operator no longer needs to continuously apply external force to maintain the clamping state. At this time, the elastic recovery member 116 will exert its elastic recovery force to drive the pressure rod 110 to move in the opposite direction, so that the clamping part automatically switches from the clamping position to the separation position. In this way, the operator can easily release the pressure reducing valve 132 without manually operating the pressure rod 110 or the pull rod 106.

[0060] Through the action of the elastic recovery member 116, the clamping portion can automatically switch from the clamping position to the separation position without manual operation by the operator. This not only improves the convenience of operation, but also reduces the risk of damage caused by improper operation. The automatic reset design makes the disassembly and assembly operations faster and more efficient. The operator can complete the disassembly and assembly tasks of the pressure reducing valve 132 more quickly, improving work efficiency. The restoring force of the elastic recovery member 116 can ensure that the clamping portion can quickly and smoothly return to the separation position when released, avoiding safety hazards caused by improper operation.

[0061] According to an embodiment of the present invention, an electromagnetic locking member 126 is further included. In the clamping position, the electromagnetic locking member 126 is suitable for locking the clamping portion to the pressure reducing valve 132 .

[0062] The design of the electromagnetic locking member 126 is based on the electromagnetic principle, and includes an electromagnet, a coil, and a necessary control mechanism. When the clamping portion moves to the clamping position and clamps the pressure reducing valve 132, the electromagnetic locking member 126 starts to work. Specifically, the coil is energized by the control mechanism, and the electromagnet generates a strong electromagnetic force, forming a firm locking state between the clamping portion and the pressure reducing valve 132. This locking state can effectively prevent the clamping portion from loosening or shifting due to external factors (such as vibration, impact, etc.) during the disassembly process, thereby ensuring the stability and safety of the operation.

[0063] The electromagnetic locking member 126 can firmly lock the pressing part on the pressure reducing valve 132 when it is in the pressing position, effectively preventing the loosening or displacement of the pressing part due to external factors, thereby greatly enhancing the stability of the operation. Through the locking effect of the electromagnetic locking member 126, it can be ensured that the pressure reducing valve 132 will not accidentally move or fall off due to operating errors or external factors during the disassembly and assembly process, thereby improving the safety of the operation. The introduction of the electromagnetic locking member 126 eliminates the need for operators to use additional tools or equipment to fix the pressing part, simplifies the operation process, and improves work efficiency. The design of the electromagnetic locking member 126 can adapt to the disassembly and assembly operations of pressure reducing valves 132 of different models and specifications, and has strong versatility and adaptability.

[0064] According to one embodiment of the utility model, the positioning assembly includes:

[0065] A positioning seat 118, the positioning seat 118 includes a fixed portion 120 and a movable portion 122, and the movable portion 122 is adapted to move relative to the fixed portion 120 to clamp the pressure reducing valve 132;

[0066] The positioning plate 124 is mounted on the base 100 , and the pressure reducing valve 132 is adapted to be limited in relative position to the base 100 by the positioning plate 124 .

[0067] The positioning assembly mainly includes a positioning seat 118 and a positioning plate 124. During operation, the operator first places the pressure reducing valve 132 on the base 100, then limits the pressure reducing valve 132 relative to the base 100 through the positioning plate 124, and then adjusts the moving part 122 of the positioning seat 118 to clamp the pressure reducing valve 132. Once the pressure reducing valve 132 is clamped and positioned, subsequent disassembly and assembly operations can be performed. This design can effectively improve the stability and accuracy of the operation and reduce the risk of damage caused by improper operation.

[0068] Through the cooperation of the positioning seat 118 and the positioning plate 124, the pressure reducing valve 132 can be accurately positioned to ensure the stability and accuracy of the pressure reducing valve 132 during the disassembly and assembly process. The design of the moving part 122 of the positioning seat 118 can adapt to pressure reducing valves 132 of different sizes and shapes, and has strong versatility and adaptability. The operator only needs to place the pressure reducing valve 132 on the positioning plate 124 and adjust the moving part 122 of the positioning seat 118 to achieve clamping and positioning, without the use of other tools or equipment, which simplifies the operation process. Accurate positioning and clamping can effectively prevent the risk of damage or falling off of the pressure reducing valve 132 due to improper operation during the disassembly and assembly process.

[0069] According to an embodiment of the present invention, a mounting hole is further provided on the base 100 , and the positioning assembly further includes a locking member 126 , and the pressure reducing valve 132 is adapted to be locked in the mounting hole through the locking member 126 .

[0070] In this embodiment, mounting holes are specially provided on the base 100. The positions and sizes of these mounting holes are designed according to the bottom structure and installation requirements of the pressure reducing valve 132 to ensure that the pressure reducing valve 132 can be stably locked on the mounting holes.

[0071] The locking member 126 is an important part of the positioning assembly and is used to firmly lock the pressure reducing valve 132 in the mounting hole. The locking member 126 can be in various forms, such as bolts, clamps, pins, etc., depending on the actual situation and operation requirements of the pressure reducing valve 132. When the pressure reducing valve 132 is placed on the mounting hole, the operator can use the locking member 126 to tightly fix the pressure reducing valve 132 and the base 100 to prevent the pressure reducing valve 132 from being displaced or tilted during the disassembly process.

[0072] During operation, the operator first places the pressure reducing valve 132 on the mounting hole of the base 100 and performs preliminary positioning through the positioning plate 124. Then, the pressure reducing valve 132 is tightly fixed to the base 100 using the locking member 126. Once the pressure reducing valve 132 is firmly locked in the mounting hole, subsequent disassembly and assembly operations can be performed. This design not only improves the stability and accuracy of the operation, but also reduces the risk of damage caused by improper operation.

[0073] By firmly locking the pressure reducing valve 132 in the mounting hole through the locking member 126, the stability of the pressure reducing valve 132 during the disassembly and assembly process can be greatly improved to prevent it from being displaced or tilted. The combination of the positioning plate 124 and the mounting hole can achieve accurate positioning of the pressure reducing valve 132, ensuring that the position and angle of the pressure reducing valve 132 are accurate during the disassembly and assembly process. The operator only needs to place the pressure reducing valve 132 on the mounting hole and fix it with the locking member 126, without the need for complex adjustment and positioning operations, thereby simplifying the disassembly and assembly process.

[0074] According to an embodiment of the present invention, there are two fixing parts 120 , and the two fixing parts 120 are arranged opposite to each other. A screw rod 128 is passed through one of the fixing parts 120 , and the screw rod 128 is connected to the moving part 122 .

[0075] The fixing part 120 is the base part of the positioning seat 118, and plays the role of supporting and positioning. In this embodiment, two fixing parts 120 are provided, and they are placed opposite to each other to form a stable clamping space. This design enables the positioning seat 118 to better adapt to pressure reducing valves 132 of different sizes and ensure the stability of the pressure reducing valve 132 during the disassembly and assembly process.

[0076] The screw 128 is an important component connecting the moving part 122 and the fixed part 120. It is inserted into one of the fixed parts 120 and connected to the moving part 122. By rotating the screw 128, the moving part 122 can be driven to move relative to the fixed part 120, thereby clamping and loosening the pressure reducing valve 132. This design allows the operator to easily adjust the clamping force to adapt to pressure reducing valves 132 of different sizes and shapes.

[0077] During operation, the operator first places the pressure reducing valve 132 in the clamping space between the two fixed parts 120, and then drives the movable part 122 to move by rotating the screw 128 until the movable part 122 is in close contact with and clamped to the pressure reducing valve 132. Once the pressure reducing valve 132 is firmly clamped on the positioning seat 118, subsequent disassembly and assembly operations can be performed.

[0078] The two oppositely disposed fixed parts 120 can form a stable clamping space to accommodate pressure reducing valves 132 of different sizes. The connection design of the screw 128 and the movable part 122 allows the operator to easily adjust the clamping force to accommodate pressure reducing valves 132 of different shapes and sizes. By rotating the screw 128 to drive the movable part 122 to move, the operator can easily clamp and release the pressure reducing valve 132. This design simplifies the operation process and improves work efficiency.

[0079] According to an embodiment of the present invention, a positioning piece is provided on the sliding portion 104, and a positioning hole is provided on the support rod 102. The sliding portion 104 is adapted to define a relative position with respect to the support rod 102 through cooperation between the positioning piece and the positioning hole.

[0080] During operation, the operator first adjusts the sliding part 104 to an appropriate position so that the positioning piece is aligned with a positioning hole on the support rod 102. Then, the positioning piece is accurately inserted into the positioning hole by pushing or rotating the sliding part 104. Once the positioning piece is fully inserted into the positioning hole, the relative position between the sliding part 104 and the support rod 102 is accurately fixed. This design can not only ensure the stability of the pressure reducing valve 132 during the disassembly and assembly process, but also improve the accuracy and reliability of the operation.

[0081] By accurately matching the positioning member with the positioning hole, it is possible to ensure that the relative position between the sliding portion 104 and the support rod 102 is accurately controlled, thereby improving the stability and reliability of the entire device.

[0082] According to an embodiment of the present invention, a rubber pad 130 is disposed on the base 100 .
