Description

Technical Field

[0001] The utility model relates to the technical field of castings, in particular to a combined valve casting. Background Art

[0002] Valve castings are usually processed by casting technology and are important components for controlling the flow of pipeline media. They can be used to isolate systems with different media or different pressures to ensure the safety of the pipeline network and the normal operation of the system.

[0003] A rotating handwheel is provided at the top of the valve casting. The valve casting adjusts the valve by rotating the handwheel. Generally, after the handwheel of the valve casting is adjusted to the optimal state, the rotating handwheel is no longer adjusted. However, if the handwheel is impacted by an external force, the handwheel may rotate, which is not conducive to the normal use of the valve casting. Summary of the Utility Model

[0004] The utility model provides a combined valve casting to solve the problem that if the handwheel is impacted by an external force, the handwheel may rotate, which is not conducive to the normal use of the valve casting.

[0005] To achieve the above object, the utility model adopts the following technical scheme: A combined valve casting includes a valve body. Flanges are fixedly connected to both ends of the valve body. An auxiliary block is fixedly connected to the top of the valve body. A rotating handwheel is arranged on the top of the auxiliary block. A fixing device is arranged on the outer surface of the rotating handwheel. The fixing device includes two extension blocks. One ends of the two extension blocks are symmetrically and fixedly connected to the outer surface of the auxiliary block. One end of the extension block is fixedly connected to a side plate. A threaded rod is threadedly connected to the inner wall of the side plate. A clamping plate is arranged at one end of the threaded rod. Rubber blocks are arranged on one sides of the two clamping plates close to each other. A groove is formed on one side of the rubber block. Support blocks are symmetrically and fixedly connected to one side of the flange. An adjusting device is arranged at the bottom of the two support blocks.

[0006] The effects achieved by the above components are as follows: By arranging two rubber blocks with grooves, rotating the threaded rod, the threaded rod will expand and contract on the inner wall of the side plate. During the expansion and contraction process of the threaded rod, the rubber blocks connected to the clamping plate will move towards each other until the outer surface of the rotating handwheel is completely abutted against the inner walls of the grooves on one sides of the two rubber blocks, so that the rotating handwheel can be fixed, which is beneficial to preventing the rotating handwheel from rotating due to external impact and facilitating the normal use of the valve casting.

[0007] Preferably, a bearing is fixedly connected to one end of the threaded rod, and the outer surface of the bearing is fixedly connected to the inner wall of the clamping plate.

[0008] The effects achieved by the above components are as follows: By setting the bearing, the friction between the threaded rod and the clamping plate can be reduced when the threaded rod is rotated, making it more labor-saving to rotate the threaded rod.

[0009] Preferably, the other end of the threaded rod is fixedly connected with an operating block, and protrusions are arranged on the outer surface of the operating block.

[0010] The effects achieved by the above components are as follows: By setting the operating block, rotating the operating block can drive the threaded rod to rotate. At the same time, protrusions are arranged on the outer surface of the operating block, which can effectively increase the friction on the outer surface of the operating block and play an anti-slip role when rotating the operating block.

[0011] Preferably, one side of the clamping plate is fixedly connected with a slider, a chute is arranged on one side of the extension block, and the outer surface of the slider is slidably connected with the inner wall of the chute.

[0012] The effects achieved by the above components are as follows: By setting the slider and the chute, when the clamping plate moves under the action of the threaded rod, the clamping plate will drive the slider to slide synchronously on the inner wall of the chute, which can play a role in limiting the clamping plate.

[0013] Preferably, mounting blocks are fixedly connected to both sides of the rubber block, and the mounting blocks are fixedly connected to the clamping plate through bolts.

[0014] The effects achieved by the above components are as follows: By setting the mounting blocks, the mounting blocks are connected to the clamping plate through bolts, which can then fix the clamping plate and the rubber block, and at the same time, it is also convenient to disassemble and replace the damaged rubber block.

[0015] Preferably, the adjusting device includes a connecting block, one side of the connecting block is fixedly connected to one end of two support blocks, the outer surface of the connecting block is slidably connected with a sleeve, and a support plate is fixedly connected to the bottom of the sleeve.

[0016] The effects achieved by the above components are as follows: By setting the connecting block and the sleeve, pushing the connecting block to slide on the inner wall of the sleeve can drive the valve body to move in the vertical direction, and then it is convenient to adjust the height of the valve body according to actual needs and can effectively support the valve body.

[0017] Preferably, a threaded pin is inserted into the inner wall of the sleeve in a threaded manner, and a rotating block is fixedly connected to one end of the threaded pin.

[0018] The effects achieved by the above components are as follows: By setting the threaded pin, rotating the rotating block drives the threaded pin to rotate, so that one end of the threaded pin abuts against one side of the connecting block, which can then fix the sleeve and the connecting block, and further fix the height of the valve body.

[0019] Preferably, an elastic rope is fixedly connected to one side of the rotating block, and one end of the elastic rope is fixedly connected to the top of the support plate.

[0020] The effect achieved by the above components is that by setting the elastic rope, it is possible to connect one side of the rotating block to the support plate, which is beneficial to preventing the problem that the threaded pin is likely to be lost after detaching from the inner wall of the sleeve.

[0021] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0022] In the present utility model, by providing a rubber block with a groove, the threaded rod can drive the rubber block connected to the clamping plate to move towards each other until the outer surface of the handwheel is completely in contact with the inner wall of the groove on one side of the two rubber blocks, then the handwheel can be fixed, which is beneficial to preventing the handwheel from rotating due to external impact and facilitating the normal use of the valve casting.
