Description

Technical Field

[0001] The present invention relates to the technical field of valves, and in particular to a convenient valve installation device and installation method. Background Art

[0002] A valve is a mechanical device used to control the flow of fluids. It controls the system flow by regulating, guiding, shutting off or diverting the fluid. Valves are widely used in various industrial, residential, commercial and water treatment fields, and are an indispensable part of the pipeline system. For the installation of small valves, bolts and flanges are generally used to directly fix the valve to the pipeline. For the installation of large valves, it is necessary to use a mounting device to support and fix the valve, and then connect it to the pipeline.

[0003] Existing patent CN202223462512.9 discloses a pump valve installation mechanism, including a pump valve body, the bottom of the outer wall at both ends of the pump valve body are fixedly connected with a fixed block, the bottom of the fixed block is provided with a mounting mechanism, the mounting mechanism includes a plurality of mounting blocks, one side of the top of the mounting block is fixedly connected with a card block, wherein the other side of the two mounting blocks is fixedly connected with a connecting block, the middle thread of the connecting block is interlaced with a screw, the bottom of both sides of the fixed block is provided with a mounting groove, and one side of the inner wall of the mounting groove is provided with a card groove. By moving the pump valve body, the inner cavity of the mounting groove on one side of the fixed block is slidably interlaced with the card block on one side of the mounting block, and then the screw is rotated, so that the connecting block drives the two mounting blocks on the other side to move together to the inner cavity of the mounting groove on the other side of the fixed block, and the card block on the other side is interlaced into the inner cavity of the card groove, and the mounting block squeezes and moves the fixed block, and the card block on the other side is interlaced with the inner cavity of the card groove, which is convenient for the installation of the pump valve body. The above patent uses a screw to drive the installation block to insert into the installation groove to install the pump valve. Since the screw is easily affected by external factors, the stability of the pump valve installation is poor. In addition, the direction of the above installation mechanism is fixed, and the position of the pump valve cannot be adjusted, which leads to poor adaptability of the installation mechanism.
