Embedded valve filtering device

Abstract

The utility model provides an embedded type valve filtering device in the field of fluid conveying system valves. The embedded type valve filtering device comprises a filtering matrix, a filtering net piece and a sealing ring. A filter mesh is arranged in the filter matrix, the filter mesh and the filter matrix are connected together in a buckling manner or in a machining forming manner, and the filter matrix is in close fit with the filter mesh. A groove is formed in the outer side of the filter matrix, and the sealing ring is positioned in the groove in the outer side of the filter matrix. According to the utility model, the fluid is completely filtered under the combined action of the filter matrix, the filter mesh and the sealing ring, so that pure fluid flows in the valve subsequently, and the leakage of the valve is reduced.

Description

Technical Field

[0001] The utility model relates to the technical field of gas delivery system valves, in particular to an embedded valve filtering device. Background Art

[0002] Filters are important components of fluid delivery systems and are mainly used for pipeline transportation of high and low pressure gases and liquids. Ball valves, needle valves, diaphragm valves, solenoid valves and pressure reducing valves are inevitably used in fluid delivery systems. The most common failure of the above valves during use is that impurities in the pipeline enter the relevant valves, causing the relevant equipment to be unable to close and damage.

[0003] The existing method is to install a simple filter before the relevant valve. However, this method cannot form a barrier with the relevant valve to completely block the passage of impurities.

[0004] However, the above method still has problems. Since the filter plate cannot form a barrier with the relevant valve to completely block the passage of impurities, this method will still cause leakage of the relevant valve. Summary of the Invention

[0005] In view of the shortcomings of existing products, the purpose of this utility model is to provide an embedded valve filtering device.

[0006] According to the utility model, an embedded valve filter device is provided, which includes a filter body, a filter mesh and a sealing ring;

[0007] A filter mesh is arranged in the filter matrix, and the filter mesh and the filter matrix are fixed by mechanically closing the filter matrix or machining the filter matrix, and a groove is arranged on the outside of the filter matrix, and the sealing ring is located in the groove of the filter matrix.

[0008] In some embodiments, the filter matrix is ​​made of stainless steel.

[0009] In some embodiments, the filter mesh is made of stainless steel and has a filtration accuracy of 0.1 microns to 50 microns.

[0010] In some embodiments, the sealing ring is made of fluororubber.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The utility model sets a filter device in front of the valve to filter the fluid completely through the filter before the valve, thereby preventing impurities from entering the relevant valve;

[0013] When the fluid containing impurities passes through the filter device, due to the sealing ring between the valve and the filter matrix, the fluid will pass through the filter screen and then enter the relevant valve, thereby blocking the impurities;

[0014] At the same time, the contact portion of the filter matrix with the filter is provided with a chamfer to increase the fluid passing area, thereby reducing the damping of the filter device on the fluid. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0021] The present invention is described in detail below with reference to specific implementations. The following implementations will help those skilled in the art further understand the present invention, but are not intended to limit the present invention in any way. It should be noted that a person skilled in the art may make various changes and improvements without departing from the concept of the present invention. These modifications and improvements fall within the scope of protection of the present invention.

[0022] like Figure 1 As shown, the present invention comprises a filter matrix 1, a filter mesh 2, and a sealing ring 3. The filter mesh 2 is disposed within the filter matrix 1, and the sealing ring 3 is disposed externally thereto. The filter matrix 1 and the filter mesh 2 are mounted in a snap-fit ​​configuration. The contact area between the filter matrix 1 and the filter mesh 2 is chamfered, and a groove is formed on the outside of the filter matrix 1. The sealing ring 3 is located within the groove of the filter matrix 1. The present invention can be applied to the front end of a valve in a fluid delivery system.

[0023] How it works

[0024] When the fluid passes through the filter device, since a sealing ring 3 is provided on the outside of the device, the fluid passage path will completely pass through the filter screen 2. Since the filter screen 2 and the filter matrix 1 are designed to be tight, impurities in the fluid will be completely isolated, thereby ensuring the purity of the fluid passing through the relevant valves, improving the reliability of the valves, and increasing the safety of subsequent related equipment.
