Description

Technical Field

[0001] This utility model relates to the field of valve body technology, specifically to an anti-clogging hydraulic valve. Background Technology

[0002] A hydraulic valve is an automated component operated by pressurized oil. It is controlled by the pressurized oil in a regulating valve and is typically used in combination with a solenoid regulating valve. It can be used for remote control of the on / off states of oil, gas, and water pipeline systems in hydropower stations.

[0003] Currently, after prolonged use, hydraulic valves often become clogged due to impurities in the liquid entering the valve body. Once clogged, the valve body needs to be replaced, making the entire operation complicated and costly. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an anti-clogging hydraulic valve. This structure can filter impurities and prevent them from clogging the valve body.

[0005] An anti-clogging hydraulic valve includes a valve body, the inlet end of which is connected to a receiving tank, a connector is connected to the receiving tank, and a filter plate is provided inside the receiving tank.

[0006] Preferably, the top wall of the receiving box is equipped with a top box with an open bottom. A spring is installed inside the top box, and one side plate of the top box is detachable. The bottom end of the spring is connected to a bottom plate. A strip-shaped hole is opened on the top wall of the receiving box, and the filter plate moves through the strip-shaped hole. The top end of the filter plate is detachably connected to the bottom plate. The filter plate can move upward and completely enter the top box. A limiting component is provided on the top wall of the receiving box, and the limiting component can limit the bottom plate.

[0007] Preferably, the limiting component includes a fixing plate, a bolt, and a blocking plate. The fixing plate is fixed to the top wall of the receiving box. The bolt passes through the fixing plate and is threadedly connected to the fixing plate. The bolt is rotatably connected to the blocking plate. The blocking plate moves through the side wall of the top box. When the bottom end of the filter plate contacts the bottom wall of the receiving box, the bottom wall of the blocking plate contacts the top wall of the bottom plate.

[0008] Preferably, the right side panel of the top box is detachably connected, and the baffle plate extends through the left wall of the top box.

[0009] Preferably, the right side plate of the top box is connected to the top box by bolts.

[0022] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0023] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0024] Example 1

[0025] like Figures 1-3 As shown, this embodiment provides an anti-clogging hydraulic valve, including a valve body 1, the inlet end of the valve body 1 is connected to a receiving tank 2, a connector 3 is connected to the receiving tank 2, and a filter plate 4 is provided inside the receiving tank 2.

[0026] In this embodiment, a receiving tank 2 is connected to the liquid inlet end of the valve body 1, and a connector 3 is installed on the receiving tank 2. The connector 3 is used to connect to the pipeline. A filter plate 4 is installed inside the receiving tank 2 to filter impurities and prevent impurities from clogging the valve body 1.

[0027] In this embodiment, the top wall of the receiving box 2 is equipped with a top box 5 with an open bottom. A spring 6 is installed inside the top box 5. One side plate of the top box 5 is detachable. The bottom end of the spring 6 is connected to a bottom plate 7. A strip-shaped hole is opened on the top wall of the receiving box 2. The filter plate 4 moves through the strip-shaped hole. The top end of the filter plate 4 is detachably connected to the bottom plate 7. The filter plate 4 can move upward and completely enter the top box 5. A limiting component is provided on the top wall of the receiving box 2. The limiting component can limit the bottom plate 7.

[0028] The limiting component described in this embodiment includes a fixing plate 9, a bolt 10, and a blocking plate 11. The fixing plate 9 is fixed to the top wall of the receiving box 2. The bolt 10 passes through the fixing plate 9 and is threadedly connected to the fixing plate 9. The bolt 10 is rotatably connected to the blocking plate 11. The blocking plate 11 movably passes through the side wall of the top box 5. When the bottom end of the filter plate 4 contacts the bottom wall of the receiving box 2, the bottom wall of the blocking plate 11 contacts the top wall of the bottom plate 7.

[0029] In this embodiment, the right side panel of the top box 5 is detachably connected, and the blocking plate 11 movably penetrates the left wall of the top box 5.

[0030] In this embodiment, the right side plate of the top box 5 is connected to the top box 5 by bolts. In this embodiment, the detachable connection is a bolt connection.

[0031] Impurities are filtered by setting up a filter plate 4. When there are too many impurities on the filter plate 4, it needs to be cleaned. The process of cleaning the filter plate 4 after disassembling the pipe and valve body 1 is complicated and inefficient. In this embodiment, a top box 5 is set up, and a spring 6 is set up inside the top box 5. The bottom end of the spring is connected to the bottom plate 7, and the bottom plate 7 is connected to the filter plate 4. During normal use, the filter plate 4 is located in the receiving box 2. The bottom wall of the baffle plate 11 contacts the top wall of the top plate 7 and presses down on the top plate 7, thereby fixing the position of the filter plate 4. When there are many impurities on the filter plate 4 and it needs to be cleaned, remove the right side plate of the top box 5, turn the bolt 10, and the bolt 10 will drive the baffle plate 11 to move to the left, so that the baffle plate 11 is separated from the top plate 7. Using the elastic restoring force of the spring 6, the filter plate 4 moves upward into the top box 5. Then remove the filter plate 4 and replace it with a new filter plate 4. Then press the top plate 7 down so that the baffle plate 11 limits the top plate 7. In this way, the process of replacing the filter plate 4 does not require removing the valve body 1. The process is simple, convenient and efficient.

[0032] In this embodiment, a liquid flow sensor is installed at the outlet end of the valve body 1. When the liquid flow sensor detects that the liquid flow rate has dropped to 95% of the normal flow rate, it means that there are already many impurities on the filter plate 4. At this time, the filter plate 4 can be replaced to ensure a normal liquid supply.

[0033] In this embodiment, a top plate 8 is connected to the top of the filter plate 4, and the top plate 8 is detachably connected to the bottom plate 7. This embodiment provides a detachable connection between the top plate 8 and the bottom plate 7 to achieve the connection between the filter plate 4 and the bottom plate 7.

[0034] In this embodiment, the top plate 8 and the bottom plate 7 are connected by bolts. The detachable connection in this embodiment is also achieved using bolts.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
