A bidirectional, interconnected two-position, two-way solenoid valve

Abstract

This utility model discloses a bidirectional, interconnected, two-position, two-way solenoid valve, including a solenoid valve body and a docking block installed at the tail end of the solenoid valve body. An electric wire is connected to the inner wall of the docking block near the electric wire. A sealing cylinder, made of rubber, is connected to the inner wall of the docking block. A docking plate is connected to the top of the sealing cylinder. This utility model inserts the sealing cylinder into the opening of the docking block at the tail end of the solenoid valve body. This causes the docking plate to align with the opening along its edge. Simultaneously, the bushing at the top of the flipping plate rotates along the shaft, compressing the positioning spring inside the flipping plate. The spring's own rebound force causes the buckle on one side of the flipping plate to engage with the groove inside the docking block. This ensures the rubber sealing cylinder is stably installed between the solenoid valve body and the electric wire, improving the sealing effect at the electric wire connection and thus extending its service life.

Description

Technical Field

[0001] This utility model belongs to the field of electromagnetic valve technology, specifically relating to a bidirectional two-position two-way electromagnetic valve. Background Technology

[0002] The bidirectional two-position two-way solenoid valve is an automated valve device used to control the opening and closing of fluid passages, belonging to a sub-type of the solenoid valve family. Its core feature is "bidirectional interoperability," meaning that fluid can flow in both directions without fixed inlet and outlet restrictions. "Two-position" refers to the valve core having two working positions: on and off, and "two-way" refers to the valve body having two ports. It is widely used in automated systems that require flexible control of bidirectional fluid flow.

[0003] In the existing bidirectional two-position two-way solenoid valve, the wiring port at the tail end needs to be connected to an external wire to achieve circuit conduction. The wiring of the solenoid valve usually uses a terminal block or plug connection. Although there is a basic insulation design, water stains can damage the insulation layer, causing micro-short circuits or leakage when energized, which in turn significantly affects the service life of the solenoid valve. Utility Model Content

[0004] The purpose of this utility model is to provide a bidirectional two-position two-way solenoid valve, which aims to solve the problem that when using a two-position two-way solenoid valve, the wiring port at its tail end needs to be connected to an external wire to achieve circuit conduction. The wiring port of the solenoid valve usually uses a terminal block or plug connection.

[0006] A sealing cylinder is connected to the inner wall of the docking block near the wire. The sealing cylinder is made of rubber. A docking plate is connected to the top of the sealing cylinder. A rotating shaft is connected to the side opening of the docking plate. A bushing is connected to the surface of the rotating shaft. A flip plate is connected to the bottom of the bushing. A buckle is connected to one side of the flip plate. A positioning spring is connected to the other side of the flip plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention involves inserting a sealing cylinder into the opening of the docking block at the tail end of the solenoid valve body. This causes the docking plate to align with the opening along the edge of the docking block. Simultaneously, the bushing at the top of the flipping plate rotates along the shaft, compressing the positioning spring inside the flipping plate. Due to the spring's own rebound force, the buckle on one side of the flipping plate engages with the groove inside the docking block. This ensures that the rubber sealing cylinder is stably installed between the solenoid valve body and the wire, improving the sealing effect at the wire connection and thus extending its service life.

A positioning spring 9 is connected to the other side of the flip plate 7.

[0024] Preferably, the mating plate 41 is made of PVC, and the openings on the surface of the mating plate 41 and the mating block 2 form a fitting structure. In actual use, the mating plate 41 is mated to the opening at the tail end of the mating block 2, which facilitates the stable installation of the sealing cylinder 4.

[0025] Preferably, the flip plate 7 forms a rotating structure with the shaft 5 via the bushing 6. Two flip plates 7 are provided, and the two flip plates 7 are symmetrically arranged about the center line of the mating plate 41. In actual use, the flip plates 7 facilitate the automatic locking of the buckle 8.

[0026] Preferably, the inner wall of the mating block 2 near the buckle 8 has a groove 10, and the buckle 8 and the groove 10 form a fitting structure. In actual use, by fitting the buckle 8 into the groove 10 on the side of the mating block 2, it is convenient to install the sealing cylinder 4 stably.

[0027] Preferably, one end of the positioning spring 9 relative to the flip plate 7 is connected to the inner wall of the side opening of the docking plate 41, and the positioning spring 9 and the flip plate 7 form an elastic linkage structure.
