Description

Technical Field

[0001] This utility model relates to the field of pipe valve technology, and specifically to a pipe valve with anti-misoperation function. Background Technology

[0002] Control valves come in various types, each with different applications. Therefore, the type of control valve should be selected appropriately according to the requirements of the production process. A control valve consists of two main assemblies: the valve body assembly and the actuator assembly (or actuator system). They are divided into four main series: single-seat series control valves, double-seat series control valves, sleeve series control valves, and self-operated series control valves. Instrument pipe fittings refer to some parts, joints, and valves that connect instruments or valves on the pipeline.

[0003] Most existing pipe valves are of the rising stem handwheel type, which makes it easy for personnel to accidentally touch the actuator, resulting in the pipe valve being closed or opened unexpectedly. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a pipe valve with anti-misoperation function, thereby solving the problem that most existing pipe valves are of the rising rod handwheel type, which easily leads to personnel accidentally touching the actuator, resulting in the pipe valve being accidentally closed or opened.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A pipe valve with anti-misoperation function includes a valve body with a protective mechanism. The protective mechanism includes two protective covers opposite to each other on both sides of the actuator of the valve body. One protective cover has a mounting post on its outer wall, and a fastening rod is rotatably mounted on the mounting post. A stop plate is provided at the end of the fastening rod away from the mounting post. A locking sleeve is slidably mounted on the fastening rod on one side of the stop plate. A drive spring is coaxially sleeved on the outer side of the fastening rod between the locking sleeve and the stop plate. The other protective cover has a fixing plate on its outer wall with a fastening groove for the fastening rod to engage after rotation. A support rod is provided on the outer wall of the protective cover, and an arc-shaped connecting plate is provided at the bottom of the support rod.

[0007] As a preferred embodiment of this utility model, the locking sleeve is provided with symmetrical auxiliary plates on both sides.

[0008] The above technical solution utilizes the auxiliary plate to facilitate the movement of the locking sleeve by the operator.

[0009] As a preferred technical solution of this utility model, a limiting groove is provided on the outer wall of the fastening rod, and a limiting block adapted to the limiting groove is provided on the locking sleeve.

[0010] By using the above technical solution and the setting of the limiting groove and the limiting block, the connection strength between the fastening rod and the locking sleeve is improved, and the locking sleeve is prevented from detaching from the fastening rod.

[0011] As a preferred technical solution of this utility model, a locking groove is provided on one side end face of the fixing plate for the fastening rod to be snapped into the fastening groove and the locking sleeve to be displaced and inserted.

[0012] The above technical solution improves the tightness of the connection between the two protective covers by using the locking groove.

[0013] As a preferred embodiment of this utility model, the connecting plate is provided with symmetrical docking plates on both sides, and the bottom end face of the docking plate is provided with a guide block.

[0014] As a preferred embodiment of this utility model, a bearing column is provided on the outer wall of the valve body, and a guide groove for the displacement of the guide block is provided on the bearing column.

[0015] By using the above technical solution and the setting of guide grooves and guide blocks, it is possible to ensure that the two protective covers move along the correct path when they are closed or separated.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] When protecting the actuator of the valve body, the protective cover is first moved towards the actuator by the support rod, causing the two protective covers to close together and form a physical enclosure, thus protecting the actuator. Then, the locking sleeve is moved by the assist plate, causing the drive spring to be compressed. Simultaneously, the fastening rod is rotated and moved, causing it to engage in the fastening groove of the fixed plate. At this point, the assist plate is loosened, and the elastic force generated by the restoring deformation of the drive spring pushes the locking sleeve towards the fixed plate, causing one end of the locking sleeve to engage in the locking groove, thereby tightly fixing the two protective covers together. This invention can protect the actuator of the valve body, preventing personnel's hands or tools from contacting the actuator and avoiding accidental opening or closing of the valve body.

[0018] When the actuator needs to be operated, the locking sleeve is first displaced by the booster plate, causing the locking sleeve to disengage from the locking groove. Then, the fastening rod is rotated to disengage from the fastening groove, releasing the limiting fixation of the two protective covers. Subsequently, the protective covers are displaced by the support rod, causing the two protective covers to separate, thereby exposing the actuator of the valve body for operation by the staff.

A support column 4 is provided on the outer wall of the valve body 1, and a guide groove 5 is provided on the support column 4 for the displacement of the guide block 8. Through the arrangement of the guide groove 5 and the guide block 8, it is possible to ensure that the two protective covers 3 move along the correct path when they are closed or separated.

[0031] refer to Figure 3 As shown, the protective mechanism includes two protective covers 3 opposite to each other on both sides of the actuator of the valve body. One protective cover 3 has a mounting post 19 on its outer side wall and a fastening rod 9 rotatably mounted on the mounting post 19. The other protective cover 3 has a fixing plate 10 on its outer side wall.

[0032] The outer wall of the protective cover 3 is provided with a support rod 2, and the bottom of the support rod 2 is provided with a connecting plate 6 with an arc structure. The two sides of the connecting plate 6 are symmetrically provided with a docking plate 7 integrally formed therewith, and the bottom end face of the docking plate 7 is provided with a guide block 8.

[0033] refer to Figure 4-6 As shown, a stop plate 14 is fixedly provided at the end of the fastening rod 9 away from the mounting post 19. The stop plate 14 prevents the drive spring 13 from disengaging from the fastening rod 9. A locking sleeve 11 is slidably provided on the fastening rod 9 on one side of the stop plate 14. A drive spring 13 is coaxially sleeved on the outside of the fastening rod 9 between the locking sleeve 11 and the stop plate 14. One end of the drive spring 13 is connected to the stop plate 14, and the other end of the drive spring 13 is connected to the locking sleeve 11. The drive spring 13 provides a thrust to the locking sleeve 11 that always faces the fixed plate 10.

[0034] The locking sleeve 11 is provided with symmetrical auxiliary plates 12 on both sides. The auxiliary plates 12 make it easier for the operator to move the locking sleeve 11.

[0035] The fastening rod 9 has a limiting groove 15 on its outer side wall, and the locking sleeve 11 has a limiting block 16 that matches the limiting groove 15. The limiting groove 15 and the limiting block 16 improve the connection strength between the fastening rod 9 and the locking sleeve 11, preventing the locking sleeve 11 from detaching from the fastening rod 9 under the action of the driving spring 13.

[0036] refer to Figure 7 As shown, the fixing plate 10 has a fastening groove 17 for the fastening rod 9 to be engaged after rotation.

[0037] The working principle and operation steps of this utility model are as follows:

[0038] When protecting the actuator of valve body 1, the support rod 2 first moves the protective cover towards the actuator of valve body 1, causing the two protective covers 3 to close together, forming a physical enclosure that covers the actuator and protects it. Then, the assist plate 12 moves the locking sleeve 11, causing the drive spring 13 to be compressed. Simultaneously, the fastening rod 9 is rotated and moved, causing it to engage in the fastening groove 17 of the fixing plate 10. At this point, the assist plate 12 is loosened, and the elastic force generated by the recovery deformation of the drive spring 13 pushes the locking sleeve 11 towards the fixing plate 10, causing one end of the locking sleeve 11 to engage in the locking groove 18, thus tightly fixing the two protective covers 3 together. This invention can protect the actuator of valve body 1, preventing personnel's hands or tools from contacting the actuator and avoiding accidental opening or closing of valve body 1.

[0039] When the actuator needs to be operated, the locking sleeve 11 is first moved by the assist plate 12, so that the locking sleeve 11 is disengaged from the locking groove 18. Then, the fastening rod 9 is rotated to move, so that the fastening rod 9 is disengaged from the fastening groove 17, and the limiting fixation of the two protective covers 3 is released. Then, the protective cover 3 is moved by the support rod 2, so that the two protective covers 3 are separated, thereby exposing the actuator of the valve body 1 for operation by the staff.
