Description

Technical Field

[0001] The utility model relates to the technical field of pressure relief valve components, in particular to a hydraulic valve component with a locking mechanism. Background Art

[0002] The hydraulic valve is an automatic component operated by pressure oil. It is controlled by the pressure oil of the pressure regulating valve and is usually used in combination with the electromagnetic pressure regulating valve. It can be used to remotely control the on and off of the oil, gas and water pipeline systems of hydropower stations. It is often used for clamping, controlling, lubricating and other oils.

[0003] When the existing hydraulic valve is in use, the valve body is limited by a locking mechanism. In the traditional limiting method, such as the utility model patent with publication number CN215719889U, screw limiting is adopted for limiting. The screw limiting method not only requires the use of tools, but also requires multiple screws to be installed multiple times, which is more troublesome to operate. Therefore, we need to consider how to solve this problem. Utility Model Content

Compared with the prior art, the pressure relief valve assembly is more convenient to operate when locking. In addition, after locking is completed, it can also achieve self-locking to avoid loosening.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] Preferably, both left and right sides of the U-shaped plate are fixedly connected with mounting plates.

[0008] Preferably, a plurality of mounting openings are provided on the two mounting plates.

[0009] Preferably, rubber pads are provided on opposite sides of the two clamping plates.

[0010] Preferably, the thread directions of the two threaded ends of the bidirectional threaded rod are opposite.

[0011] Preferably, the locking structure includes a rotating column rotatably connected to the rear side of the U-shaped plate, the front end of the rotating column extends into the slide groove and is fixedly connected to the rear side of the bidirectional threaded rod, the rear end of the rotating column is provided with a rectangular groove, a rectangular rod that can slide back and forth is arranged in the rectangular groove, the front end of the rectangular rod is elastically connected to the front inner wall of the rectangular groove by a spring, the rear end of the rectangular rod is fixedly connected to a pull plate, the front side of the pull plate is fixedly connected to a plurality of limit rods, the rear side of the U-shaped plate is provided with a plurality of limit grooves, and the plurality of limit grooves all cooperate with the limit rods.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The use of the two-way threaded rod facilitates the limiting of the hydraulic valve body. During the entire limiting process, the two-way threaded rod only needs to be rotated to limit and release the limit, thereby improving the efficiency of the actual limiting. In addition, a locking structure is also provided. By using the locking structure, after the limiting is completed, the rectangular rod will drive the pull plate and the limit rod to be inserted into the limit groove for locking, thereby avoiding the possibility of loosening after the two-way threaded rod is connected.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-Figure 3, a hydraulic valve assembly with a locking mechanism, comprising a U-shaped plate 1, a slide groove 6 is provided at the inner bottom of the U-shaped plate 1, a bidirectional threaded rod 8 is rotatably connected between the front and rear inner walls of the slide groove 6, the two threaded ends of the bidirectional threaded rod 8 have opposite thread directions, the two threaded ends of the bidirectional threaded rod 8 are threadedly connected with sliders 9, each slider 9 is slidably connected to the inner wall of the slide groove 6, the upper ends of the two sliders 9 are fixedly connected with clamping plates 5, a hydraulic valve body 3 is placed at the inner bottom of the U-shaped plate 1, the hydraulic valve body 3 is located between the two clamping plates 5, the front end of the bidirectional threaded rod 8 extends to the outside, and is fixedly connected with a torsion block 4, and rubber pads are provided on the opposite sides of the two clamping plates 5;

[0020] The left and right sides of the U-shaped plate 1 are fixedly connected with mounting plates 2, and the two mounting plates 2 are provided with a plurality of mounting openings;

[0021] Among them, it also includes a locking structure, which is used to lock the rotation of the bidirectional threaded rod 8. The locking structure includes a rotating column 11 rotatably connected to the rear side of the U-shaped plate 1. The front end of the rotating column 11 extends into the slide groove 6 and is fixedly connected to the rear side of the bidirectional threaded rod 8. A rectangular groove 15 is provided at the rear end of the rotating column 11. A rectangular rod 14 that can slide back and forth is provided in the rectangular groove 15. The front end of the rectangular rod 14 is elastically connected to the front inner wall of the rectangular groove 15 through a spring 7. The rear end of the rectangular rod 14 is fixedly connected to a pull plate 10. The front side of the pull plate 10 is fixedly connected to a plurality of limit rods 12. A plurality of limit grooves 13 are provided on the rear side of the U-shaped plate 1, and the plurality of limit grooves 13 are all matched with the limit rod 12.

[0022] In the present invention, when the hydraulic valve body 3 needs to be locked, the hydraulic valve body 3 is placed on the mounting plate 2, and then the pull plate 10 is pulled to allow the limiting rod 12 to leave the corresponding limiting groove 13, and then the torsion block 4 and the pull plate 10 are rotated synchronously. At this time, the bidirectional threaded rod 8 rotates, driving the two sliders 9 to move relative to each other, thereby driving the two clamping plates 5 to move relative to each other, and clamping and limiting the hydraulic valve body 3. Compared with the prior art, the locking and limiting method is simpler. In addition, after the limiting is completed, the pull plate 10 is released. Under the elastic action of the spring 7, the rectangular rod 14 will drive the pull plate 10 and the limiting rod 12 to insert into the limiting groove 13 to lock, thereby avoiding the possibility of loosening of the bidirectional threaded rod 8 after connection.
