Liquid pressure valve structure and application method thereof

Abstract

The invention discloses a liquid pressure valve structure and an application method thereof. The liquid pressure valve structure comprises a pressure valve body, a pressure adjusting plug, a transmission rod, a pressure adjusting spring and a threaded rod, wherein the pressure adjusting plug is arranged in the pressure valve body; the transmission rod is fixed to the interior of the pressure adjusting plug in a penetrating mode; a guide plate penetrates through the upper portion of the transmission rod; the outer surface of the transmission rod is connected to a sealing ring; the guide plate is embedded in the pressure valve body; the pressure adjusting spring is arranged above the transmission rod; the upper end of the pressure adjusting spring is connected to a pressing plate; and the threaded rod penetrates through the interior of the pressing plate. The liquid pressure valve structure is provided with a rotating wheel, a baffle and an ejector block, unilateral control over the rotating direction of a driving block can be achieved through connection of the baffle and the rotating wheel, and contact between the baffle and the rotating wheel can be adjusted through rotation of the ejector block, so that the rotating direction of the subsequent driving block is adjusted, the driving block can be driven to continuously rotate through reciprocating motion in a single direction subsequently, and the operation is more convenient.

Description

technical field [0001] The invention relates to the technical field of pressure valves, in particular to a structure of a liquid pressure valve and an application method thereof. Background technique [0002] The pressure valve is also called a pressure regulating valve or a pressure regulating valve. It is a common flow regulating control device. It can automatically adjust the pressure of the internal fluid through its own internal spring to ensure that the fluid pressure at the subsequent output end is constant. There are also some deficiencies in existing liquid pressure valves in use: [0003] The performance of the internal spring of the existing liquid pressure valve will decrease after a long time of use, resulting in a decrease in the adjustment sensitivity of the device, and subsequent replacement of the spring is more cumbersome, reducing the service life of the device The rotation of the threaded rod is relatively laborious, and the operation is difficult under ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a liquid pressure valve structure and its use method, to solve the problem that the performance of the internal spring of the existing liquid pressure valves on the market proposed by the above background technology will decrease after a long time of use, thus As a result, the adjustment sensitivity of the device is reduced, the subsequent replacement of the spring is more cumbersome, and the service life of the device is reduced, and the rotation of the threaded rod is laborious when adjusting the spring pressure, and the operation is difficult under the limitation of the external space.
