Description

Technical Field

[0001] The utility model relates to the technical field of valve body devices, and particularly to a valve body device with an adjusting mechanism. Background Technique

[0002] The main function of the valve body is to block water flow or air flow to achieve the opening and closing of the valve and flow control. It usually forms a seal together with the valve core and the valve seat sealing ring to effectively bear the medium pressure. The material of the valve body also varies according to different application environments, and the commonly used materials include cast iron, cast steel, stainless steel, carbon steel, plastic, copper, etc.

[0003] At present, most valve bodies drive the rotation of the valve stem by rotating the control disk, so that the valve core rotates. Since there is no setting to prevent accidental touch of the control disk, it is easy to cause accidental touch of the valve body. In view of this, we propose a valve body device with an adjusting mechanism. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a valve body device with an adjusting mechanism, which can solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the valve body device with an adjusting mechanism proposed by the utility model includes a valve body. A protective shell seat is fixedly connected to the outer wall of the valve body. A valve stem is rotatably connected inside the valve body. An adjusting mechanism is arranged at the top of the valve stem. A valve core is fixedly connected to the bottom of the valve stem. The adjusting mechanism includes:

[0006] A support ring seat, which is fixedly connected to the top of the valve body;

[0007] An adjusting turntable, which is rotatably connected to the top of the support ring seat;

[0008] A limit nut, which is threadedly connected to the outer wall of the valve stem.

[0009] Preferably, a force-bearing seat is fixedly connected to the top of the adjusting turntable. A force-bearing rod is inserted into the top of the support ring seat. An insertion hole is arranged at the top of the force-bearing seat, and the force-bearing rod can be inserted into the insertion hole.

[0010] Preferably, a support ring plate is fixedly connected to the outer wall of the support ring seat. A sliding block is slidably connected to the inner wall of the support ring plate. A through groove is arranged on the support ring plate, and the sliding block is slidably connected inside the through groove. A clamping groove is arranged on the sliding block.

[0011] Preferably, a fixing column is fixedly connected to the top of the support ring seat. A clamping block is sleeved on the outer wall of the fixing column. A through hole is arranged on the clamping block, and the force-bearing rod is inserted into the inner wall of the through hole. The clamping block is clamped in the clamping groove on the sliding block.

[0012] Preferably, a spring is welded to the bottom of the sliding block, and the end of the spring away from the sliding block is welded to the outer wall of the support ring seat. The sliding block is inserted into the inner wall of the adjusting turntable by the extrusion of the spring.

[0013] Preferably, a protective cover is snap-fitted to the inner wall of the protective housing seat. A limiting rod is fixedly connected to the inner wall of the protective cover. There are two groups of limiting rods, one group is circular and the other group is semicircular. Corresponding notch grooves are provided on the protective housing seat to facilitate the close fitting of the limiting rod and the protective housing seat.

[0014] The utility model provides a valve body device with an adjusting mechanism, which has the following beneficial effects:

[0015] (1) By snap-fitting the clamping block with the sliding block, and then passing the stress rod through the clamping block again and inserting it into the inner wall of the support ring seat, the clamping block is limited, and at the same time the sliding block is also limited, so that the adjusting turntable is limited and the valve stem is fixed, ensuring the fixed state of the valve core and avoiding the situation that the valve body device is accidentally touched by the staff.

[0016] (2) By pulling out the stress rod and inserting it into the stress seat, the limiting state of the clamping block is released, and the clamping block is moved away from the sliding block. At this time, the adjusting turntable can be rotated by moving the stress rod. The adjusting turntable is fixed on the valve stem through the limiting nut, and the valve stem is driven to rotate. Since a limiting hole with a fixed angle is provided at the bottom of the adjusting turntable, it is convenient for the staff to quickly rotate the adjusting turntable to a specified angle, improving the work efficiency.

[0025] Please refer to Figures 1 - 4 , the present utility model provides a valve body device with an adjusting mechanism, including a valve body 1, a protective housing seat 2 is fixedly connected to the outer wall of the valve body 1, a valve stem 3 is rotatably connected to the inside of the valve body 1, an adjusting mechanism 4 is arranged at the top of the valve stem 3, a valve core 5 is fixedly connected to the bottom of the valve stem 3, and the adjusting mechanism 4 includes a support ring seat 41, the support ring seat 41 is fixedly connected to the top of the valve body 1, an adjusting turntable 42 is rotatably connected to the top of the support ring seat 41, and a limit nut 43 is threadedly connected to the outer wall of the valve stem 3.

[0026] In the present utility model, a force-bearing seat 44 is fixedly connected to the top of the adjusting turntable 42, a force-bearing rod 45 is inserted into the top of the support ring seat 41, a limit hole is opened at the bottom of the adjusting turntable 42, a total of six groups of limit holes are provided, and the angles between each limit hole are the same. An insertion hole is arranged at the top of the force-bearing seat 44, and the force-bearing rod 45 can be inserted into the insertion hole. By inserting the force-bearing rod 45 into the force-bearing seat 44, it is convenient to drive the adjusting turntable 42 to rotate by moving the force-bearing rod 45. A support ring plate 46 is fixedly connected to the outer wall of the support ring seat 41, a sliding block 47 is slidably connected to the inner wall of the support ring plate 46, a through groove is opened on the support ring plate 46, the sliding block 47 is slidably connected to the inside of the through groove, and a clamping groove is opened on the sliding block 47.

[0027] Furthermore, a fixing column 6 is fixedly connected to the top of the support ring seat 41. A clamping block 7 is sleeved on the outer wall of the fixing column 6. A through hole is formed in the clamping block 7, and a stress rod 45 is inserted into the inner wall of the through hole. The clamping block 7 is clamped in the clamping groove on the sliding block 47. A spring 8 is welded to the bottom of the sliding block 47, and one end of the spring 8 away from the sliding block 47 is welded to the outer wall of the support ring seat 41. By squeezing the sliding block 47 with the spring 8, the sliding block 47 is inserted into the inner wall of the adjusting turntable 42, and then the adjusting turntable 42 is limited by the sliding block 47. If the clamping block 7 is clamped into the sliding block 47 again, the limiting work of the sliding block 47 on the adjusting turntable 42 can be further ensured. A protective cover 9 is clamped in the inner wall of the protective shell seat 2. A limiting rod 10 is fixedly connected to the inner wall of the protective cover 9.
