Description

Technical Field

[0001] The utility model belongs to the technical field of reversing valve components, and particularly relates to a high-pressure wet electromagnetic reversing valve. Background Technique

[0002] A reversing valve is a direction control valve with more than two flow forms and more than two oil ports. It is a valve that realizes the communication, cut-off and commutation of hydraulic oil flow, as well as pressure unloading and sequence action control. It is a direction control valve that relies on the relative movement of the spool and the valve body, and there are two types: rotary valve type and spool valve type.

[0003] After retrieval, a wet electromagnetic reversing valve that is convenient for installation disclosed in Chinese Patent Application No. 202021530565.8 includes an electromagnetic reversing valve body. Two first square frames and two second square frames are sleeved in the middle of the electromagnetic reversing valve body. A connecting mechanism is arranged between the two first square frames and the two second square frames. The connecting mechanism consists of four connecting blocks and four bolts. Fixed blocks are fixedly connected to the top and bottom of the front surface of the two second square frames, and a clamping mechanism is arranged between the four fixed blocks. For this wet electromagnetic reversing valve that is convenient for installation, through the cooperation of the threaded rod, the movable plate, the square plate and the clamping plate, people can rotate the two threaded rods, so that the four movable plates approach each other, and then the four clamping plates clamp the pipeline. When people rotate the two threaded rods in the opposite direction, the four clamping plates loosen the pipeline, and there is no need to use a welding machine to weld the electromagnetic reversing valve body to the pipeline, which facilitates the installation of the electromagnetic reversing valve body.

[0004] Although the above patent can install the electromagnetic reversing valve body to the pipeline without using a welding machine, which facilitates the installation of the electromagnetic reversing valve body, in actual use, the patent clamps the pipeline with four clamping plates. During the use process, due to the vibration generated by the wet electromagnetic reversing valve during use, it will shift during the use process, that is, the four clamping plates may rotate around the pipeline, thereby driving the electromagnetic reversing valve to rotate, making it difficult to ensure its installation with high stability.

[0005] Therefore, it is necessary to transform the wet electromagnetic reversing valve in the above patent to effectively prevent the wet electromagnetic reversing valve from shifting during use and solve the problem that it is difficult to ensure its installation with high stability.

A latch is slidably connected to the inner wall of the lifting hole, and the bottom of the latch is fixedly connected to the tooth plate, and the tops of the two latches are fixedly connected to the same handle.

[0008] The beneficial effects of the utility model are as follows:

[0009] 1.
