Description

Technical Field

[0001] The utility model relates to the technical field of two-position three-way solenoid valves, in particular to a small-caliber two-position three-way solenoid valve. Background Art

[0002] The two-position three-way solenoid valve is controlled by two coils. One coil is energized for a moment and then the power is turned off, the valve is opened, and the other coil is energized for a moment and then the power is turned off, the valve is closed. It can remain closed or open for a long time, which can extend the life of the coil. However, some small two-position three-way solenoid valves now only use one set of coils for control. However, due to the small flow channel inside the small-caliber two-position three-way solenoid valve, when some media flow through, the particles in the media are easily attached to the flow channel inside the valve body, causing it to become blocked. For this reason, we propose a small-caliber two-position three-way solenoid valve. Utility Model Content

[0003] In view of the problems in the prior art, the utility model provides a small-caliber two-position three-way solenoid valve.

[0004] The technical solution adopted by the utility model to solve the technical problem is a small-caliber two-position three-way solenoid valve, comprising a valve body, a vertical pipe is installed on the bottom surface of the valve body, and a horizontal pipe is integrally constructed on the outer periphery of the vertical pipe, and there are three groups of horizontal pipes, a ring seat is screwed on the inner side of the horizontal pipe, and a ring ring is screwed on the side of the ring seat close to the horizontal pipe, and a filter screen layer for filtering and intercepting is installed on the inner side of the ring ring;

[0005] The outer periphery of the transverse tube is integrally structured with a tube seat, and the inner wall surface of the transverse tube is provided with a sewage discharge hole connected to the tube seat, a plug is threadedly installed on the inner side of the tube seat, and an end of the tube seat away from the transverse tube is provided with an external thread.

[0006] By adopting the above technical solution, when a small-caliber two-position three-way solenoid valve is used, the ring seat screwed and installed on the inner side of the horizontal tube on the outer periphery of the vertical tube at the bottom of the valve body is convenient for disassembly and assembly, and the filter layer in the ring ring inside the ring seat can filter and intercept the medium flowing through the valve body, so that the particles that can cause blockage are intercepted, which is convenient for reducing the blockage in the flow channel inside the valve body, and the ring seat and the ring ring are convenient for disassembly and assembly, and are convenient for replacement;

[0007] When a large amount of impurities accumulate on the inner periphery of the ring seat, the plug on the outer periphery of the pipe seat can be rotated so that the plug can be screwed apart and release the blocked hole on the inner periphery of the pipe seat, so that the impurities accumulated inside the ring seat can be discharged from the drain hole, and the external thread on the outer periphery of the pipe seat can be connected to the drain pipe, so that the impurities can be discharged to a suitable position, so that the filter layer in the ring seat and the ring ring can continue to be used and protect the solenoid valve.

[0008] Specifically, a rubber pad abutting against the ring seat is clamped on the inner periphery of the transverse tube.

[0009] By adopting the above technical solution, the rubber pad can help improve the tightness of the ring seat being screwed into the cross pipe.

[0010] Specifically, a rubber ring abutting against the ring is clamped on the inner side of the ring seat.

[0011] By adopting the above technical solution, the rubber ring can help improve the tightness of the ring when installed in the ring seat.

[0012] Specifically, the inner circumferential surface of the ring seat is integrally constructed with arc blocks, and there are multiple groups of arc blocks, and the inner circumference of the ring ring is integrally constructed with conical strips.

[0013] By adopting the above technical solution, the tapered strips on the inner circumference of the ring are convenient for auxiliary support of the filter layer and improve the strength of the ring. At the same time, the arc-shaped blocks on the inner circumference of the ring seat make it easier to disassemble and assemble the ring seat.

[0014] Specifically, a hexagonal groove is formed on one side of the plug located outside the pipe seat.

[0015] By adopting the above technical solution, the hexagonal groove on the outer periphery of the plug makes it easier to disassemble and assemble the plug.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. The technical solution of the present application adopts the design of the vertical pipe, horizontal pipe, ring seat, ring ring and filter layer. When a small-diameter two-position three-way solenoid valve is used, the ring seat screwed on the inner side of the horizontal pipe on the outer periphery of the vertical pipe at the bottom of the valve body is convenient for disassembly and assembly, and the filter layer in the ring ring inside the ring seat can filter and intercept the medium flowing through the valve body, so that the particulate matter that can cause blockage is intercepted, which is convenient for reducing the blockage in the flow channel inside the valve body, and the ring seat and the ring ring are convenient for disassembly and assembly, and are convenient for replacement.

[0018] 2. The technical solution of the present application adopts the design of the drain hole, pipe seat, plug and external thread. When a large amount of impurities are accumulated on the inner periphery of the ring seat, the plug on the outer periphery of the pipe seat can be rotated to separate the plug and release the blocked hole on the inner periphery of the pipe seat, so that the impurities accumulated inside the ring seat can be discharged from the drain hole, and the external thread on the outer periphery of the pipe seat can be interconnected with the drain pipe, so that the impurities can be discharged to a suitable position, so that the filter layer in the ring seat and the ring ring can continue to be used and protect the solenoid valve.

[0028] like Figure 2 and Figure 3 As shown, a rubber pad 11 abutting against the ring seat 4 is clamped on the inner periphery of the transverse tube 3 .
