A hydraulic balance regulating valve

Abstract

The utility model relates to the technical field of regulating valves, specifically a hydraulically balanced regulating valve, comprising a valve body, a valve cover fixedly mounted on the top of the valve body, a fixed sleeve fixedly mounted on the top of the valve cover, a valve stem connected to the central sliding sleeve of the fixed sleeve, a connecting plate fixedly mounted on the top of the valve stem, and a fixing frame for the lifting and lowering movement of the connecting plate on the top of the valve cover. The connecting plate slides along the cylinder in the slide groove, so that the valve stem can move along the fixed sleeve to ensure the stable movement of the valve stem, thereby reducing the pressure of the water flow in the valve body. When the water flows in through the water inlet, the impurities in the water flow can be filtered through the filter screen. When the water flow is closed, the force of part of the medium passing through the connecting hole can be balanced with the force under the plug sleeve, eliminating most of the unbalanced forces inside the valve body, reducing the vibration caused by the flow of the medium, increasing the stability of the medium flow, and improving the overall use experience of the device.

Description

Technical Field

[0001] The utility model relates to the technical field of regulating valves, in particular to a hydraulic balance regulating valve. Background Art

[0002] The regulating valve, also known as the control valve, is the final control element in the field of industrial automation process control. It receives the control signal output by the regulating control unit and uses power operation to change the process parameters such as medium flow, pressure, temperature, and liquid level. With the increasing demand for fluid control technology in the industrial and civil fields, the performance of the regulating valve, as an important component in fluid control, directly affects the operating stability and efficiency of the entire system. In many applications such as water treatment systems, heating systems, and cooling systems, the regulation of hydraulic balance is particularly important.

[0003] For most of the hydraulic balance regulating devices of the heating pipe network, when collecting and discharging water, the drainage pipe connections of the hydraulic balance regulating devices of the heating pipe network often cause impurities and dirt to adhere to the connections due to the impact of water pressure, thereby forming sedimentation blockage.

[0004] Control valves generally have unstable problems in flow regulation. Cleaning deposited impurities is time-consuming and laborious. In addition, when closed, the stability of the medium passing through is poor and maintenance is more complicated. These all affect the overall user experience of the control valve. Utility Model Content

[0005] The utility model aims to provide a hydraulic balance regulating valve, which has the characteristics of filtering medium impurities and maintaining the balanced and stable pressure of medium fluid.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a hydraulic balancing regulating valve, comprising a valve body and a valve cover fixedly mounted on the top of the valve body, a fixed sleeve fixedly mounted on the top of the valve cover, a valve stem being connected to the central sliding sleeve of the fixed sleeve, a connecting plate fixedly mounted on the top of the valve stem, a fixing frame for the lifting and lowering movement of the connecting plate being provided on the top of the valve cover, a filter assembly for treating impurities being provided inside the valve body, and a base for cleaning impurities being provided at the bottom of the valve body.

[0008] In order to ensure stable sliding movement of the valve stem, as a preferred hydraulic balance regulating valve of the utility model, the inner side of the fixing frame has a spring for squeezing the connecting plate, the spring is sleeved with the cylinder, and the spring is located on the top of the connecting plate.

[0009] In order to filter impurities in the water flow, as a preferred hydraulic balancing regulating valve of the utility model, the filter assembly includes a plug sleeve, the plug sleeve is fixedly installed on the inner side of the valve body, the bottom of the plug sleeve has a filter net for filtering impurities, and the base is threadedly sealed with the bottom of the valve body.

[0010] In order to facilitate the smooth flow of water, as a preferred hydraulic balance regulating valve of the utility model, a valve plug is fixedly installed on the bottom of the valve stem, the valve plug is adaptively matched with the plug sleeve, and a connecting hole for water flow is opened on the inner side of the valve plug.

[0011] In order to ensure the stable flow of the fluid, as a preferred hydraulic balance regulating valve of the utility model, a water inlet for water intake and a water outlet for water discharge are respectively opened on the inner side of the valve body.

[0012] In order to clean up the accumulated impurities, as a preferred hydraulic balance regulating valve of the utility model, the water inlet is located below the plug sleeve, the water outlet is located above the plug sleeve, and the base corresponds to the water inlet.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] By sliding the connecting plate along the cylinder in the slide groove, the valve stem can be moved along the fixed sleeve to ensure the stable movement of the valve stem, thereby reducing the pressure of the water flow in the valve body. When the water flows in through the water inlet, the impurities in the water flow can be filtered through the filter screen. After the water flow is closed, the accumulated impurities can be cleaned up by disassembling the base. Through the setting of the valve plug and the connecting hole, the water flow can flow through the connecting hole, reducing the impact of the water flow pressure on the valve plug during flow. When the water flow is closed, the force of part of the medium passing through the connecting hole can be balanced with the force under the plug sleeve, eliminating most of the unbalanced forces inside the valve body, reducing the vibration caused by the flow of the medium, increasing the stability of the medium flow, and improving the overall use experience of the device.

[0027] As a technical optimization solution of the utility model, the filter assembly includes a sleeve 15, which is fixedly installed on the inner side of the valve body 1. The bottom of the sleeve 15 has a filter screen 16 for filtering impurities, and the base 11 is threadedly sealed with the bottom of the valve body 1.

[0028] In this embodiment, by providing the filter screen 16 , when the medium from the water inlet 9 flows into the valve body 1 , the impurities entering can be filtered through the filter screen 16 , thereby filtering the impurities in the water.
