Description

Technical Field

[0001] The utility model relates to the technical field of regulating valves, in particular to a regulating valve with a blockage clearing mechanism. Background Art

[0002] A regulating valve, also known as a control valve, is a device used to control process parameters such as fluid flow, pressure, temperature and liquid level. It achieves precise regulation of the medium flow by changing the flow area between the valve core and the valve seat. A regulating valve usually consists of two parts: an actuator and a valve. The actuator is the power part of the regulating valve, responsible for driving the change of the valve opening according to the control signal, while the valve is the part that actually controls the flow of the medium.

[0003] A regulating valve is disclosed in a Chinese utility model patent with publication number CN213451948U, including a valve body, a valve cover fixedly connected to the top of the valve body by fastening screws, a support frame fixedly connected to the top of the valve cover, a valve stem movably connected to the inner surface of the support frame by a bearing, a hand wheel fixedly connected to the top of the valve stem, a measuring ruler fixedly connected to the left side of the top of the support frame, and the valve body including a base layer, a first functional layer and a second functional layer.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the transported fluid passes through the regulating valve. Since the fluid contains impurities, the impurities in the fluid can easily cause the regulating valve to be blocked during flow, thus affecting the normal use of the regulating valve and reducing the service life of the regulating valve. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a regulating valve with a blockage clearing mechanism.

[0006] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a regulating valve with a clearing mechanism, comprising a regulating valve body, a mounting tube fixed to the water inlet of the regulating valve body, a filter screen arranged on the inner wall of the mounting tube, a brushing assembly for brushing the filter screen installed on the mounting tube, the brushing assembly comprising a fixing plate fixed to the inner wall of the mounting tube, a cross bar penetrating and rotatably connected to the side wall of the fixing plate, and a cleaning brush arranged at the end of the cross bar, the bristles of the cleaning brush are tightly pressed against the surface of the filter screen, a collecting port is opened at the bottom of the mounting tube, a collecting box is arranged at the bottom of the mounting tube, a mounting plate is fixed to the side wall of the mounting tube, a bottom plate is fixed to the side wall of the collecting box, the bottom plate is fixed to the mounting plate by bolts, and a driving assembly for driving the cross bar to rotate is installed on the mounting tube.

[0007] By adopting the above technical scheme, the fluid enters the regulating valve body through the installation pipe, and the filter in the installation pipe filters the impurities in the fluid, thereby reducing the probability of impurities clogging the regulating valve. The driving assembly drives the cross bar to rotate, so that the cleaning brush brushes the surface of the filter. The impurities on the surface of the filter are brushed by the cleaning brush and fall into the collection box, which makes it easy for the staff to remove the collection box to clean the impurities, thereby reducing the probability of the filter being blocked after long-term use.

[0008] Furthermore, the driving assembly includes a driving motor fixed to the top of the mounting tube, the output shaft of the driving motor passes through the mounting tube and is rotatably connected, the driving assembly also includes a rotating shaft fixed to the end of the output shaft of the driving motor, a driving bevel gear fixed to the lower end of the rotating shaft, and a driven bevel gear fixed to the end of the cross bar away from the cleaning brush and meshing with the driving bevel gear.

[0009] By adopting the above technical solution, when the surface of the filter needs to be scrubbed, the staff only needs to drive the rotating shaft to rotate through the driving motor, so that the driven bevel gear and the driving bevel gear meshing with the driven bevel gear rotate, so that the cleaning brush rotates with the driven bevel gear and scrubs the surface of the filter, reducing the probability of impurities clogging the mesh of the filter.

[0010] Furthermore, a mounting block is fixed to one end of the cross bar away from the driven bevel gear, the cleaning brush is arranged at the bottom of the mounting block, and a fixing component for fixing the cleaning brush is installed on the cleaning brush, and the fixing component includes a vertical rod that is penetrated and slidably connected to the cleaning brush, a rotating block fixed to the lower end of the vertical rod, and a stud fixed to the upper end of the vertical rod and threadedly connected to the mounting block.

[0011] By adopting the above technical solution, when the cleaning brush needs to be disassembled, the staff removes the collection box from the mounting tube, rotates the vertical rod and the stud by the rotating block, so that the stud is disengaged from the mounting block, thereby removing the cleaning brush, which is convenient for maintenance and cleaning of the cleaning brush.

[0012] Furthermore, a sealing gasket is fixed on the upper surface of the collection box.

[0013] By adopting the above technical solution, the sealing gasket is made of rubber material with good sealing performance. The collection box cooperates with the installation tube and presses against the sealing gasket, which enhances the sealing between the collection box and the collection port and reduces the probability of fluid leakage from the collection port.

[0014] Furthermore, the driving bevel gear and the driven bevel gear are both provided with a galvanized layer.

[0015] By adopting the above technical scheme, zinc has good calendering, wear resistance, corrosion resistance, castability, and good mechanical properties at room temperature. The setting of the galvanized layer improves the rust and corrosion resistance of the driving bevel gear and the driven bevel gear, which is beneficial to the normal use of the drive assembly.

[0016] Furthermore, a protective cover for covering the driving motor is fixed on the top of the mounting tube.

[0017] By adopting the above technical solution, the protective cover protects the drive assembly and reduces the probability of damage to the drive assembly under the action of external force.

[0018] Furthermore, a transparent window is provided at the top of the installation tube near the filter screen.

[0019] By adopting the above technical solution and setting the transparent window, the staff can observe the filter through the transparent window, which is convenient for the staff to observe the blockage of the filter.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. In the present application, the fluid enters the regulating valve body through the installation pipe, and the filter in the installation pipe filters the impurities in the fluid, thereby reducing the probability of impurities blocking the regulating valve. The driving assembly drives the crossbar to rotate, so that the cleaning brush scrubs the surface of the filter. The impurities on the surface of the filter fall into the collection box after being scrubbed by the cleaning brush, which makes it convenient for the staff to remove the collection box to clean the impurities, thereby reducing the probability of the filter being blocked after long-term use.

[0022] 2. In the present application, when the filter surface needs to be scrubbed, the staff only needs to drive the rotating shaft to rotate through the driving motor, so that the driven bevel gear and the driving bevel gear meshed with the driven bevel gear rotate, so that the cleaning brush rotates with the driven bevel gear and scrubs the filter surface, reducing the probability of impurities clogging the filter mesh.

[0023] 3. In this application, when the cleaning brush needs to be removed, the staff removes the collection box from the mounting tube, and then rotates the vertical rod and the stud by rotating the block to disengage the stud from the mounting block, thereby removing the cleaning brush for easy maintenance and cleaning of the cleaning brush.
