Description

Technical Field

[0001] This utility model relates to the field of filter valve body technology, and in particular to a valve body with a detachable and washable filter element. Background Technology

[0002] Y-type filter valves, also known as Y-shaped filter valves, are a common device in pipeline systems that transport media. They are equipped with an internal filter element to remove impurities from the media, prevent particulate impurities from entering the channel and causing blockages, and protect the fittings on the equipment pipeline from wear and clogging. When cleaning is required, simply remove the removable filter element, clean it, and reinstall it.

[0003] However, the installation of filter elements in such filter valves is generally done by pressing the top of the filter element with a threaded cap and fixing the filter element with the friction of the threads. The threaded connection relies on manual tightening torque. Over time, the threads are easily loosened due to vibration or uneven force caused by the impact of fluid in the main valve body, and the filter element may even fall off, resulting in filtration failure or other issues. In addition, a flange is designed at the port of the filter chamber of the main valve body. The filter element is aligned with the flange of the main valve body through the flanged cap and fixed with multiple bolts. This is cumbersome because it requires aligning each bolt during installation and disassembly.

[0004] Based on the above situation, we propose a valve body with a detachable filter element for cleaning to solve the above problems. Utility Model Content

[0005] This invention provides a valve body for detachable cleaning filter elements to solve the problems existing in the prior art.

[0006] The technical problem solved by this utility model is achieved by the following technical solution:

[0007] A valve body for a detachable and washable filter element includes a main valve body and a filter chamber connected to the main valve body. A filter element is installed inside the filter chamber. An end cap is detachably connected to the end of the filter chamber. An abutment seat is connected to the inner wall of the end cap. A snap-fit ​​seat is also provided inside the end cap. Multiple positioning plates are equidistantly arranged along the circumference of the filter element's axis. The snap-fit ​​seat has positioning holes for inserting the positioning plates. Elastic positioning plates corresponding to the positioning plates are provided on the inner wall of the snap-fit ​​seat. These elastic positioning plates are evenly distributed along the circumference of the snap-fit ​​seat, and their length extension directions converge at the axis of the snap-fit ​​seat, forming a radial layout centered on the axis of the snap-fit ​​seat. When the end cap moves the abutment seat away from the axis of the snap-fit ​​seat, the elastic positioning plates abut against the positioning plates, thus fixing the filter element.

[0008] Preferably, the elastic positioning plate is provided with a protruding locking part, and the positioning plate body is provided with a locking groove corresponding to the protruding locking part.

[0009] Preferably, one end of the positioning plate extends to the port of the filter element to resist the radial deformation caused by the water flow impacting the filter element.

[0010] Preferably, the inner wall of the filter cavity is provided with an annular flange, and the outer wall of the filter element is provided with an abutment sealing ring.

[0011] Preferably, the end cap and the filter chamber are detachable by means of a threaded connection, and the outer wall of the end cap is provided with anti-slip texture and polygonal protrusions.

[0012] Preferably, the diameter of the abutment gradually increases towards the elastic positioning plate.

[0013] The beneficial effects of this utility model are as follows: after the end cap is connected to the filter cavity, the end cap drives the contact seat to contact the elastic positioning plate to connect with the positioning plate, thereby stably installing the filter element in the filter cavity, enhancing the connection stability of the filter element. Moreover, during disassembly and assembly, it is only necessary to rotate the end cap in the opposite direction to drive the contact seat to disengage from the elastic positioning plate, thereby releasing the contact with the positioning plate, which facilitates the disassembly and assembly of the filter element and makes it more convenient.

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0022] Reference Figures 1-5 As shown, a valve body for a detachable cleaning filter element includes a main valve body 1 and a filter chamber 2 connected to the main valve body 1. A filter element 3 is installed inside the filter chamber 2. An end cap 21 is detachably connected to the open end of the filter chamber 2. An abutment seat 22 is connected to the inner wall of the end cap 21. Multiple positioning plates 31 are equidistantly arranged along the circumference of the filter element 3. The valve body also includes a snap-fit ​​seat 4. The snap-fit ​​seat 4 has positioning holes 41 for inserting the positioning plates 31. The inner wall of the snap-fit ​​seat 4 has a corresponding positioning hole for inserting the positioning plates 31. A corresponding elastic positioning plate 42 is provided. The elastic positioning plate 42 can be made of a material such as a metal elastic sheet that can return to its initial state when not subjected to external force. Multiple elastic positioning plates 42 are evenly distributed along the circumference of the locking seat 4, and their length extension directions converge at the axis of the locking seat 4, forming a radial layout centered on the axis of the locking seat 4. When the end cover 21 drives the abutment seat 22 to abut against the elastic positioning plate 42 and move away from the axis of the locking seat 4, the elastic positioning plate 42 abuts against the positioning plate body 31 to fix the filter element 3.

[0023] Specifically, when installing the filter element 3, first insert the positioning plate 31 into the positioning hole 41, and then place it into the filter chamber 2. Next, connect the end cap 21 to the filter chamber 2. At this time, the end cap 21 will cause the contact seat 22 to abut against the elastic positioning plate 42. The movable end of the elastic positioning plate 42 moves towards the positioning plate 31 and abuts tightly against it. Under the action of the positioning plate 31, the filter element 3 is tightly installed on the locking seat 4. For disassembly, simply remove the end cap 21. The contact seat 22 releases its contact with the elastic positioning plate 42. At this time, the elastic positioning plate 42 will reset under its own elastic force and move away from the positioning plate 31, thereby releasing its contact with the positioning plate 31. At this time, the filter element 3 can be removed for cleaning. The installation and removal of the filter element 3 can be completed in a short time, improving the efficiency of filter element installation and removal. It is especially suitable for occasions where frequent cleaning of filter elements is required, such as in some chemical pipelines where the medium contains a lot of particulate impurities. The cost of downtime cleaning is high, and quick installation and removal can shorten the downtime.

[0024] Reference Figures 3-4 As shown, in order to further improve the installation stability of the filter element 3, a protruding snap-fit ​​part 43 is provided on the elastic positioning plate 42, and a snap-fit ​​groove 32 corresponding to the protruding snap-fit ​​part 43 is provided on the positioning plate 31. When the elastic positioning plate 42 abuts against the positioning plate, it drives the protruding snap-fit ​​part 43 into the snap-fit ​​groove 32, thereby reducing the axial movement of the filter element 3.

[0025] Among them, reference Figure 3 As shown, one end of the positioning plate 31 extends to the port of the filter element 3. The positioning plate 31 can be made of metal materials with a certain hardness, such as stainless steel or aluminum alloy, and can be connected to the filter element 3 by welding or other fixed connection methods. When the fluid flows into the installation cavity at high speed from the inlet end of the main valve body 1 and impacts the filter element 3, the hollow filter screen structure of the filter element 3 may expand or deform due to the water pressure squeezing the filter screen outward. Multiple positioning plates 31 surrounding the filter element 3 form a ring support structure, which disperses the radial force generated by the water flow impact to the entire ring area, avoiding excessive local stress on the filter element 3 and causing damage, thus resisting the radial deformation caused by the water flow impact on the filter element 3.

[0026] Reference Figure 2 As shown, further, an annular flange 5 is provided on the inner wall of the filter chamber 2, and an abutment sealing ring 6 is provided on the outer wall of the filter element 3. The abutment sealing ring 6 can be made of elastic materials such as rubber or silicone. When the snap-fit ​​seat 4 is connected to the filter element 3, it is subjected to the abutment force of the end cap 21 and the abutment seat 22, so that the abutment sealing ring 6 and the annular flange 5 are tightly abutted, and a seal is formed between the lower end of the filter element 3 and the filter chamber 2 to prevent water leakage.

[0027] The end cap 21 and the filter chamber 2 are detachable by a threaded connection, which makes the installation of the end cap 21 convenient and quick. The outer circumference of the end cap 21 is provided with anti-slip texture 7, which allows the end cap 21 to be manually screwed on under low torque conditions. However, in some high torque demand scenarios, manual screwing cannot achieve the connection effect. The bottom outer wall of the end cap 21 is also provided with polygonal protrusions 8 to facilitate operation with tools such as wrenches.

[0028] Reference Figure 4As shown, the diameter of the contact seat 22 gradually increases towards the elastic positioning plate 42. As the end cap 21 connects with the filter chamber 2, the end cap 21 drives the contact seat 22 to move into the filter chamber 2. At this time, the inclined surface of the contact seat 22 will continuously increase the contact force on the elastic positioning plate 42, thereby making the connection between the elastic positioning plate 42 and the positioning plate 31 tighter, and at the same time, the connection with the snap-fit ​​seat 4 will be tighter, so that the snap-fit ​​seat 4 and the bottom surface of the filter chamber 2 are in close contact, reducing the possibility of the snap-fit ​​seat 4 driving the filter element 3 to rotate.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
