Description

Technical Field

[0001] The utility model relates to the technical field of valve equipment, in particular to a one-way valve filtering structure. Background Art

[0002] A check valve, commonly known as a one-way valve, allows fluid to flow only through the inlet but not back through the outlet. Also known as a non-return valve or check valve, it is used in hydraulic systems to prevent reverse flow of oil or in pneumatic systems to prevent reverse flow of compressed air. Check valves come in two types: straight-through and right-angle. Straight-through check valves are installed in the pipeline using a threaded connection.

[0003] Since one-way valves are usually installed in pipelines, and in the early stages of industrial system commissioning, some industrial waste such as welding slag and scraps will remain during the system construction process, mainly inside pipelines and liquid storage tanks, which will cause the following problems in actual operation:

[0004] 1) Due to the characteristics of garbage such as self-weight and entanglement, it cannot be completely cleaned up in the initial stage of system commissioning. It is necessary to clean the pipe garbage every time it is operated for a period of time, which will affect the smooth operation of the equipment;

[0005] 2) The one-way valve has a simple structure and only plays the role of one-way flow. If large particles flow into the one-way valve, the one-way valve has no filtering effect. Such large particles will cause damage to the high-precision valve downstream of the entire pipeline. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the inventors have conducted in-depth research and completed the present utility model after paying a lot of creative work.

[0007] Specifically, the technical problem to be solved by the present invention is to provide a one-way valve filtering structure to solve the technical problem that the current one-way valve can only connect the fluid in one direction, the structure is simple, and large particles of garbage in the pipeline will damage and block the one-way valve. At the same time, every time the one-way valve filtering equipment is cleaned, the entire one-way valve needs to be disassembled before the filtering equipment can be removed.

[0008] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0009] A one-way valve filtering structure comprises a connecting pipe, a one-way valve is fixedly mounted on the outer surface of the connecting pipe, and a filtering mechanism is provided on the outer surface of the connecting pipe away from the one-way valve;

[0010] The filtering mechanism includes a filter box, the top of which is fixedly connected to the outer surface of the connecting pipe, the inner surface of the filter box is fixedly installed with a filter assembly, the filter assembly includes a filter mesh box, the outer surface of the filter mesh box is slidably connected to the inner surface of the filter box, and the top of the filter mesh box is fixedly installed with an interception net.

[0011] As an improved technical solution, the filtering mechanism further includes a fixing assembly, which includes a fixing plate, the top of which is fixedly connected to the bottom of the filter box, and a No. 1 fixing block is fixedly installed on both sides of the fixing plate.

[0012] As an improved technical solution, the fixing assembly also includes a No. 2 fixing block, and the opposite sides of the two No. 2 fixing blocks are fixedly connected to the outer surface of the filter box. The bottom of the No. 1 fixing block is fixedly installed with a bolt, and the outer surface of the bolt is threaded with a nut.

[0013] As an improved technical solution, the top ends of the bolts pass through the No. 1 fixing block and the No. 2 fixing block and extend to the outside of the No. 2 fixing block, and the bottom end of the nut is fixedly connected to the top end of the No. 2 fixing block.

[0014] As an improved technical solution, the angle between the interception net and the filter box is 60 degrees.

[0015] As an improved technical solution, there are four intercepting nets and filter boxes, which are placed from left to right in the filter box.

[0016] After adopting the above technical solution, the beneficial effects of the utility model are:

[0017] 1. The utility model adds a design to block the residual particles in the liquid in the pipeline. Through the coordinated use of the one-way valve and the connecting pipe, the fluid first passes through the connecting pipe and then enters the one-way valve. Through the coordinated use of the connecting pipe and the filter box and the filter box and the interception net, the particle garbage in the fluid is intercepted and stored, and the garbage of different particle sizes in the fluid is blocked, thereby avoiding the problem that the one-way valve has a simple structure and can only connect the fluid in one direction, the large particle garbage in the pipeline will damage and block the one-way valve, and the particle garbage will cause damage to the high-precision valve downstream of the entire pipeline. The particle garbage is cleaned up in the early stage of system debugging.

[0018] 2. The utility model adds a design in which the one-way valve garbage blocking device can be cleaned and replaced without disassembling the one-way valve. By using bolts and nuts in conjunction with the No. 1 fixing block and the No. 2 fixing block, the No. 1 fixing block and the fixing plate, the No. 2 fixing block and the filter box, and the No. 1 fixing block in conjunction with the filter box and the interception net, the fixing plate equipped with the filter assembly can be taken out of the filter box, avoiding the problem of needing to dismantle the entire one-way valve for cleaning or replacement when cleaning or replacing the filtering equipment in the one-way valve.

[0030] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown together, this embodiment provides a one-way valve filtering structure, which includes a connecting pipe 1, a one-way valve 2 fixedly mounted on the outer surface of the connecting pipe 1, and a filtering mechanism 3 disposed on the outer surface of the connecting pipe 1 away from the one-way valve 2;

[0031] The filtering mechanism 3 includes a filter box 31, the top of the filter box 31 is fixedly connected to the outer surface of the connecting pipe 1, and a filter assembly 32 is fixedly installed on the inner surface of the filter box 31. The filter assembly 32 includes a filter mesh box 321, the outer surface of the filter mesh box 321 is slidably connected to the inner surface of the filter box 31, and an interception net 322 is fixedly installed on the top of the filter mesh box 321.

[0032] There are filter openings on the filter box 321 and the interception net 322, which can block particles in the liquid.

[0033] like Figure 1 、 Figure 2 and Figure 3 As shown together, the filter mechanism 3 also includes a fixing assembly 33 , which includes a fixing plate 331 , the top of which is fixedly connected to the bottom of the filter box 321 , and a No. 1 fixing block 332 is fixedly installed on both sides of the fixing plate 331 .

[0034] The fixing plate 331 is used to take the filter box 321 and the interception net 322 out of the filter box 31, so as to quickly and easily clean up the intercepted particles.

[0035] like Figure 1 、 Figure 2 and Figure 3 As shown together, the fixing assembly 33 also includes a No. 2 fixing block 333, and the opposite sides of the two No. 2 fixing blocks 333 are fixedly connected to the outer surface of the filter box 31. The bottom of the No. 1 fixing block 332 is fixedly installed with a bolt 334, and the outer surface of the bolt 334 is threadedly installed with a nut 335.

[0036] like Figure 1 and Figure 4 As shown together, the top ends of the bolts 334 pass through the No. 1 fixing block 332 and the No. 2 fixing block 333 and extend to the outside of the No. 2 fixing block 333 , and the bottom end of the nut 335 is fixedly connected to the top end of the No. 2 fixing block 333 .

[0037] The rotation of the nut 335 will drive the second fixing block 333 and the first fixing block 332 to move inward, so that the first fixing block 332 and the fixing plate 331 are tightly attached to the bottom of the filter box 31, so that the solution flowing into the filter box 31 will not overflow, ensuring the sealing of the connecting pipe 1 and the one-way valve 2.

[0038] like Figure 2 、 Figure 3 and Figure 4 As shown together, the angle between the interception net 322 and the filter box 321 is 60 degrees.

[0039] The 60-degree angle can guide the liquid to flush the interception filter 322 and push the particles intercepted by the interception filter 322 into the filter box 321 .

[0040] like Figure 3 As shown, there are four interception nets 322 and filter boxes 321, and they are placed from left to right in the filter box 31.

[0041] The four intercepting nets 322 and the filter box 321 have different filter mesh holes. The pores are arranged from coarse to fine from left to right, blocking particles from coarse to fine in the liquid. The intercepting net 332 and the filter box 321 are made of stainless steel.

[0042] When in use, the user first fixes the connecting pipe 1 carrying the one-way valve 2 to the pipeline, and the liquid in the pipeline flows into the connecting pipe 1, and then the particles in the liquid are blocked by the interception leakage net 322 and guided into the filter box 321 by the impact force of the liquid flow, so that the particles in the liquid are stored in the filter box 321. Particles of different coarseness and fineness in the liquid are intercepted by the four interception leakage nets 322, so that the particles from coarse to fine in the liquid are intercepted. When the equipment has been running for a period of time, the user first shuts off the liquid flowing into the connecting pipe 1, and then uses a wrench to loosen the bolt 334 and the nut 335 to loosen the No. 1 fixing block 332 and the No. 2 fixing block 333, and then moves the fixing plate 331 connected to the No. 1 fixing block 332 downward. The fixing plate 331 drives the filter box 321 and the interception leakage net 322 to move downward, and the filter box 321 containing particles is taken out of the filter box 31, which is convenient for cleaning the filter box 321 and the interception leakage net 322.

[0043] It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of protection of the present invention. In addition, it should be understood that after reading the technical content of the present invention, those skilled in the art may make various changes, modifications and / or variations to the present invention, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
