A split-type pneumatic control valve

Abstract

This utility model discloses a split-type pneumatic regulating valve, including a regulating valve body, an actuating power end, and a filter assembly. A valve cover is installed at the top of the regulating valve body, and fixing holes are evenly distributed at the top of the regulating valve body. The fixing holes cooperate with fixing bolts to install the valve cover at the top of the regulating valve body. A connecting seat passes through the middle of the valve cover, and the actuating power end is installed at the upper end of the connecting seat. A valve stem passes through the connecting seat, and a valve core is installed at the bottom end of the valve stem. A filter assembly is installed below the valve core. This invention solves the problem that in the prior art, during actual maintenance of the regulating valve, it is necessary to first remove the sealing cover before loosening the connection structure between the threaded rod and the support cylinder to remove the movable filter plate. This process is cumbersome, time-consuming, and requires repeated tightening of bolts, resulting in low cleaning efficiency and difficulty in meeting the needs of rapid maintenance.

Description

Technical Field

[0001] This utility model relates to the field of regulating valve technology, specifically to a split-type pneumatic regulating valve. Background Technology

[0002] A pneumatic control valve is an automated control device powered by compressed air, used to regulate parameters such as flow rate, pressure, and temperature in industrial processes. Its core function is to adjust the flow channel area by changing the position of the valve core, thereby achieving precise control of the medium.

[0003] A split-type pneumatic regulating valve disclosed in Publication No. CN219866357U is described as follows: "It includes a valve body, a mounting base fixedly connected to the top of the valve body, a valve cover fixedly installed on the top of the mounting base, a valve stem slidably sleeved on the valve cover, a pneumatic actuator connected to one end of the valve stem, a valve core fixedly connected to the other end of the valve stem, a valve seat slidably sleeved on the valve core, the valve seat fixedly installed in the valve body, a filter cylinder fixedly connected to one end of the valve seat, a filter plate abutting the other end of the valve seat, a groove recessed on the end face of the filter plate near the valve core, a movable filter plate slidably installed in the groove, a threaded rod rotatably connected to one end of the movable filter plate, a support cylinder sleeved on the threaded structure, a movable filter plate fixedly connected to one end of the support cylinder, a sealing cover fixedly connected to the other end of the support cylinder, the sealing cover fixedly installed at the lower end of the drain pipe, and the drain pipe fixedly connected to the bottom of the valve body."

[0004] However, the aforementioned split-type pneumatic control valve has the following disadvantages:

[0005] Although the regulating valve in this patent can be used to clean the inner wall of the valve seat and the inner wall of the filter cylinder through the movable filter plate and the threaded rod, in actual maintenance, the sealing cover must be removed first before the connection structure between the threaded rod and the support cylinder can be loosened to remove the movable filter plate. This process is cumbersome, takes a long time to disassemble, and requires repeated tightening of bolts, resulting in low cleaning efficiency and difficulty in meeting the needs of rapid maintenance.

[0006] To address the aforementioned problems, this application proposes a split-type pneumatic control valve. Utility Model Content

[0007] To address the problems in related technologies, this utility model provides a split-type pneumatic regulating valve, which simplifies the disassembly process and meets the needs of rapid cleaning.

[0008] Therefore, the specific technical solution adopted by this utility model is as follows:

[0009] A split-type pneumatic control valve includes a control valve body, an actuating power end, and a filter assembly. A valve cover is installed at the top of the control valve body, a connecting seat passes through the middle of the valve cover, an actuating power end is installed at the upper end of the connecting seat, a valve stem passes through the connecting seat, a valve core is installed at the bottom end of the valve stem, and a filter assembly is installed below the valve core.

[0010] The filter assembly includes a filter cartridge, one end of which is equipped with a differential pressure sensor. The other end of the differential pressure sensor is installed at the water inlet end of the inlet pipe. The filter cartridge is mounted on a device base, which is fixedly mounted on a sealing cover. The sealing cover is threadedly connected to the mounting groove at the bottom of the regulating valve body.

[0011] As a further embodiment of this utility model, the bottom end of the filter cartridge is threadedly connected to the outer wall of the equipment base, and an auxiliary end is fixedly installed at the bottom end of the sealing cover.

[0012] As a further embodiment of this utility model, the top end of the regulating valve body is provided with fixing holes, which are used in conjunction with fixing bolts to install the valve cover on the top end of the regulating valve body.

[0013] As a further embodiment of this utility model, an inlet pipe is connected to the left side wall of the regulating valve body, and an outlet pipe is connected to the right side wall of the regulating valve body.

[0014] As a further embodiment of this utility model, a first connecting flange is fixedly installed at the left end of the inlet pipe.

[0015] As a further embodiment of this utility model, a second connecting flange is fixedly installed at the right end of the outlet pipe.

[0016] As a further embodiment of this invention, the top end of the valve stem is connected to the actuating power end.

[0017] The beneficial effects of this utility model are as follows:

[0018] This utility model utilizes a control valve body, an actuator, and a filter assembly that work together. In use, the actuator drives the valve core to move up and down within the control valve body via the valve stem, thus completing the control operation. When the filter cartridge needs maintenance, the maintenance personnel only need to use a wrench and auxiliary end to unscrew the sealing cap to easily remove the filter cartridge. After removing the old filter cartridge from the equipment base, the new filter cartridge is installed on the equipment base to complete the maintenance operation. This simplifies the disassembly process during maintenance and meets the need for rapid cleaning. Attached Figure Description
