A ball valve handle mounting mechanism

Abstract

This utility model relates to the field of ball valve manufacturing technology and discloses a ball valve handle installation mechanism. The mechanism includes a base frame, a bracket fixedly connected to the top end face of the base frame, a pneumatic handle mounted on the top end face of the base frame, a clamping assembly on the top end face of the base frame, and an auxiliary installation assembly on the top end face of the base frame. In this ball valve handle installation mechanism, a hinge block blocks the path of the handle's upward movement, ensuring that the handle will not fall off during installation or under vibration, improving the stability of the auxiliary installation assembly in clamping the handle. A spring pushes a lifting plate to abut against the bottom of the handle, tightly restricting the handle between the lifting plate and the hinge block. This prevents the handle from loosening or wobbling, automatically compensates for gaps, provides a stable feel during operation, and further prevents the handle from loosening under vibration, impact, or repeated operation, resulting in higher installation reliability.

Description

Technical Field

[0001] This utility model relates to the field of ball valve manufacturing technology, specifically to a ball valve handle mounting mechanism. Background Technology

[0002] A ball valve is a common type of shut-off valve. It uses a ball with a circular through-hole as the opening and closing element, and rotates 90° to open or close the pipeline. Ball valves have a simple structure, good sealing performance, and are easy to operate. They are widely used in petroleum, natural gas, chemical, and water treatment industries. Because the flow resistance of a ball valve is extremely small when fully open, it hardly affects the flow of the medium. It also has the advantages of rapid opening and closing, long service life, and convenient maintenance. Therefore, it is often used in situations where it is necessary to quickly cut off or connect fluids. The installation of the ball valve handle is the last step in the ball valve assembly process. A nut is used to lock the ball valve handle onto the ball valve.

[0003] However, each size of handle has a corresponding tightening torque for its locking nut. When the installation torque of the ball valve handle locking nut is less than the required torque, the nut will fall off during use, rendering the ball valve unusable. Excessive torque can damage the handle. Therefore, we propose a ball valve handle installation mechanism. Utility Model Content

[0004] The purpose of this invention is to provide a ball valve handle mounting mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a ball valve handle mounting mechanism, comprising a base frame, a bracket fixedly connected to the top end face of the base frame, a pneumatic handle disposed on the top end face of the base frame, a clamping assembly disposed on the top end face of the base frame, and an auxiliary mounting assembly disposed on the top end face of the base frame, the auxiliary mounting assembly comprising:

[0006] An optical axis, the side wall of which is fitted with a grip sleeve, and the outer wall of the grip sleeve is threaded with a pusher;

[0007] A rotating head, wherein a hinge block is hinged to the top end face of the rotating head, and a vertical rod is fixedly connected to the inner wall of the rotating head;

[0008] A spring, wherein a lifting plate is provided on the top of the spring.

[0009] Preferably, the clamping assembly is slidably connected to the top end face of the base frame, and the clamping assembly is linked to the pneumatic handle.

[0010] Preferably, the optical axis is fixedly connected to the top end face of the base frame, and the side wall of the grip is threaded with bolts, which are used to install the grip on the side wall of the optical axis.

[0011] Preferably, the rotating head is rotatably connected to the grip, the hinge block is L-shaped, and the inner wall of the rotating head has a groove, which is movably connected to the hinge block.

[0012] Preferably, the vertical rod is slidably connected to the lifting plate, the lifting plate is slidably connected to the inner wall of the rotating head, and the lifting plate pushes the ball valve handle upward.

[0013] Preferably, the inner bottom surface of the rotating head is provided with a groove, the inner bottom surface of the groove abuts against the spring, and the top end of the spring abuts against the bottom end surface of the lifting plate.

[0014] Preferably, a rubber strip is fixedly connected to the top end face of the lifting plate, and a protrusion is provided on the top of the rubber strip. The protrusion has two directions, and the two directions of the protrusion are arranged in opposite directions.

[0015] Compared with the prior art, the present invention provides a ball valve handle mounting mechanism, which has the following advantages:

[0016] 1. This ball valve handle mounting mechanism uses an auxiliary mounting component to fix the handle, facilitating installation and ensuring the handle is positioned within the correct torque range. The hinge block blocks the upward slippage of the handle, preventing it from falling off during installation or under vibration. This enhances the stability of the auxiliary mounting component's grip on the handle. A spring pushes the lifting plate against the bottom of the handle, tightly securing the handle between the lifting plate and the hinge block. This prevents the handle from becoming loose or wobbly, automatically compensating for gaps. The mechanism provides a stable feel during operation and further prevents the handle from loosening under vibration, impact, or repeated operation, resulting in higher installation reliability.

[0017] 2. This ball valve handle mounting mechanism uses a rubber strip to prevent the handle from slipping when clamped. The two protrusions in opposite directions form a serrated engagement on the surface, which will offset any slight forward or backward rotation of the handle, thus maintaining stability.

[0024] like Figures 1-5 As shown, this utility model provides a technical solution: a ball valve handle installation mechanism, including a base frame 1, a bracket 2 fixedly connected to the top end face of the base frame 1, a pneumatic handle 3 provided on the top end face of the base frame 1, a clamping assembly 4 provided on the top end face of the base frame 1, and an auxiliary installation assembly 5 provided on the top end face of the base frame 1. The auxiliary installation assembly 5 includes an optical shaft 501, a grip sleeve 502, a pusher 503, a rotating head 504, a hinge block 505, a vertical rod 506, a spring 507, and a lifting plate 509.

[0025] In one embodiment of this utility model, the optical axis 501 is fixedly connected to the top end face of the base frame 1, a grip 502 is sleeved on the side wall of the optical axis 501, a pusher 503 is threadedly connected to the outer wall of the grip 502, and a bolt is threadedly connected to the side wall of the grip 502. The grip 502 is installed on the side wall of the optical axis 501 by the bolt.

[0026] The rotating head 504 is rotatably connected to the grip sleeve 502. A hinge block 505 is connected to the top end face of the rotating head 504. The hinge block 505 is L-shaped. A groove is provided on the inner wall of the rotating head 504. The groove is movably connected to the hinge block 505.

[0027] A vertical rod 506 is fixedly connected to the inner wall of the rotary head 504. The vertical rod 506 is slidably connected to the lifting plate 509. The lifting plate 509 is slidably connected to the inner wall of the rotary head 504. The lifting plate 509 pushes the ball valve handle upward. A groove is provided on the inner bottom surface of the rotary head 504. The inner bottom surface of the groove abuts against the spring 507. The top of the spring 507 abuts against the bottom end face of the lifting plate 509.

[0028] The clamping assembly 4 is slidably connected to the top end face of the base frame 1, and the clamping assembly 4 is linked with the pneumatic handle 3.

[0029] First, place the ball valve to be tested on the bracket 2. Move the pneumatic handle 3 to control the clamping cylinder in the clamping assembly 4 to clamp both sides of the ball valve on which the handle needs to be installed. Adjust the position of the grip 502 and manually move the grip 502 in a circular and vertical direction on the optical axis 501 through the pusher 503. At the same time, under the rotation of the rotating head 504, control the ball valve handle into the groove of the rotating head 504. Then, rotate the pusher 503 so that the pusher 503 is tightly abutted against the outer wall of the optical axis 501, locking the grip 502 on the optical axis 501 to complete the fixation of the ball valve handle. Finally, install the handle onto the ball valve using a torque tool. Through the auxiliary installation assembly 5 and the clamping assembly 4, the ball valve and the handle are fixed, which facilitates the installation of the handle and ensures that the handle is set within the correct torque range.

[0030] When the ball valve handle is installed on the rotary head 504, press the ball valve handle down to push the hinge block 505 downward. The inner wall of the rotary head 504 has a groove, and the hinge block 505 enters the groove. At this time, the handle can enter the interior of the rotary head 504. Then, the hinge block 505 rotates in the opposite direction under the action of gravity, so that the hinge block 505 blocks the path of the handle sliding upward, ensuring that the handle will not fall off during installation or under vibration, and improving the stability of the auxiliary installation component 5 in clamping the handle. When disassembly is required, simply lift the end of the hinge block 505 away from the rotary head 504 downward, so that the hinge block 505 re-enters the groove. At this time, the path of the handle moving upward is opened.

[0031] Spring 507 pushes the lifting plate 509 to abut against the bottom of the handle, tightly restricting the handle between the lifting plate 509 and the hinge block 505. This prevents the handle from becoming loose or wobbly, automatically compensates for gaps, provides a stable feel during operation, and further prevents the handle from loosening during vibration, impact, or repeated operation, resulting in higher installation reliability.

[0032] In addition, a rubber strip 6 is fixedly connected to the top end face of the lifting plate 509. The top of the rubber strip 6 is provided with a protrusion. The protrusion is arranged in two directions, and the two directions of the protrusion are arranged in opposite directions. The rubber strip 6 itself has a large coefficient of friction, which can prevent the handle from slipping in the clamping state. The two protrusions in opposite directions form a sawtooth-like engagement on the surface. No matter if the handle has a slight tendency to rotate back and forth, it will be canceled by the protrusion, thus maintaining stability.

[0033] In this utility model, during use, the auxiliary installation component 5 and the clamping component 4 are used to fix the ball valve and the handle, facilitating the installation of the handle. Pressing the ball valve handle downward causes it to push the hinge block 505 downward, allowing the handle to enter the interior of the rotating head 504. Under the action of gravity, the hinge block 505 rotates in the opposite direction, blocking the path of the handle's upward movement and ensuring that the handle will not fall off during installation or under vibration. The spring 507 pushes the lifting plate 509 to abut against the bottom of the handle, tightly restricting the handle between the lifting plate 509 and the hinge block 505. This prevents the handle from becoming loose or wobbling, automatically compensating for gaps and improving installation reliability.

[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
