Description

Technical Field

[0001] This utility model relates to the field of electromagnetic valve technology, and in particular to a two-position three-way valve. Background Technology

[0002] A solenoid valve is an automated actuator that uses electromagnetic force to control the on / off state or flow direction of fluid. It is widely used in industrial, civil, and specialized fields. Its core principle is that the magnetic field generated by energizing an electromagnetic coil drives the valve core to move, thereby changing the on / off state or flow direction of the fluid passage. A two-position three-way valve is a control device that quickly switches fluid passages by moving the valve core.

[0003] In existing technologies, traditional valve cores are made of rubber. Rubber is prone to softening, aging, and even decomposition at high temperatures, leading to sealing failure. In cold environments, rubber may harden and crack, affecting sealing performance. Rubber has limited tolerance to chemical media such as strong acids, strong alkalis, and organic solvents, and is easily corroded or swollen. Rubber valve cores are prone to wear under frequent switching or high pressure, leading to deformation or leakage of the sealing surface. Rubber materials age over time, reducing elasticity and decreasing sealing performance. If high-temperature and corrosion-resistant rubber materials are required, the cost will increase significantly, and customization will be difficult. Therefore, it is necessary to improve a two-position three-way valve to solve the above problems. Utility Model Content

[0004] To overcome the problems of sealing failure, affecting sealing performance, deformation or leakage of sealing surface, and increased cost caused by the rubber material of two-position three-way valves.

[0005] The technical solution of this utility model is as follows: a two-position three-way valve, including a coil housing, a first outlet and an adjusting component, a valve body for limiting the internal components at the bottom of the coil housing, an inlet pipe for introducing liquid and an outlet pipe for facilitating liquid outflow on the valve body, a contactor for connecting electricity on the coil housing, a hexagonal nut on the coil housing, an adjusting component inside the valve body, a first outlet inside the valve body, a second outlet inside the valve body, an inlet inside the valve body, a valve cover for sealing the internal groove of the valve body, a first sealing ring between the valve cover and the valve body, a valve core body movably connected inside the valve body, a valve core guide hole inside the valve core body, a connecting seat on the valve body, a second sealing ring and a flat gasket between the connecting seat and the valve body, and a pin inside the valve core body.

[0006] Preferably, the valve core has several flow guide holes, and these flow guide holes are evenly distributed inside the valve core body.

[0007] Preferably, a flow guide groove is provided between the water inlet and the flow guide hole of the valve core, and a valve cover is provided on the flow guide groove to seal it.

[0008] Preferably, the valve body has a groove at the corresponding position of the valve core body, and the valve core body slides inside the groove.

[0009] Preferably, the adjustment assembly includes a blocking tube disposed inside the coil housing. A first magnetic chuck is disposed inside the blocking tube. A common flat washer is disposed between the hexagonal nut and the coil housing. A second magnetic chuck is slidably connected inside the coil housing. A return spring is fixedly connected between the second magnetic chuck and the first magnetic chuck.

[0010] Preferably, the isolation tube has a groove at the corresponding position of the second magnetic attractor, and the second magnetic attractor slides inside the groove.

[0011] Preferably, the second magnetic component has a corresponding groove inside the reset spring, and the reset spring moves inside the groove.

[0012] The beneficial effects of this utility model are:

[0013] 1. Compared to two-position three-way valves made of rubber, this valve uses a sliding valve core body within the valve body to discharge the liquid flowing in from the inlet, aligning with the first and second outlet positions. The valve core body is made of metal, and the distance between the valve core body and the valve body is one to two micrometers. The valve core body will not soften, age, or even decompose in high-temperature environments, ensuring the airtightness of the device. It also prevents the valve core body from hardening in cold environments, ensuring the sealing performance of the device. Furthermore, it is not subject to corrosion by organic solvents, preventing wear of the rubber valve core due to frequent switching or high pressure. It eliminates the need for custom-made special rubber materials, reducing costs. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figure 1 - Figure 5 This utility model provides an embodiment of a two-position three-way valve, including a coil housing 1, a first outlet 801, and an adjusting assembly. A valve body 2, which limits the movement of the internal components, is located at the bottom of the coil housing 1. An inlet pipe 3 for introducing liquid and an outlet pipe 4 for facilitating liquid outflow are provided on the valve body 2. An electrical connector 5 and a hexagonal nut 6 are provided on the coil housing 1. The adjusting assembly is located inside the valve body 2. The first outlet 801 is located inside the valve body 2. A second outlet 802 and an inlet 803 are located inside the valve body 2. A valve cover 804, which seals the internal opening of the valve body 2, is provided on the valve body 2. A first sealing ring 805 is provided between the valve cover 804 and the valve body 2. A valve core body 811 is movably connected inside the valve body 2. A valve core guide hole 806 is provided inside the valve core body 811. A connecting seat 807 is provided on the valve body 2. A second sealing ring 808 and a flat gasket 809 are provided between the connecting seat 807 and the valve body 2. A pin 810 is provided inside the valve core body 811. The valve core body 811 slides to a suitable position inside the valve body 2, and the water inlet 803 introduces the water flow. The water moves inside the valve core body 811 and is discharged through the valve core guide hole 806 and the first outlet 801 and the second outlet 802.

[0022] Please see Figure 2 - Figure 3In this embodiment, several valve core guide holes 806 are provided, and these several valve core guide holes 806 are evenly provided inside the valve core body 811. The several valve core guide holes 806 are provided to reduce water pressure during water flow. A guide groove is provided between the inlet 803 and the valve core guide holes 806, and a valve cover 804 is provided on the guide groove to seal it. The guide groove provided between the inlet 803 and the valve core guide holes 806 guides the direction of water flow. A sliding groove is provided at the corresponding position of the valve core body 811 in the valve body 2. The valve core body 811 slides inside the sliding groove. The sliding groove provided inside the valve body 2 at the corresponding position of the valve core body 811 limits the movement of the valve core body 811 when it slides inside the sliding groove. The valve core body 811 is made of metal, and the distance between the valve core body 811 and the valve body 2 is one to two micrometers.

[0023] Please see Figure 4 - Figure 5 In this embodiment, the adjustment assembly includes a barrier tube 902, which is disposed inside the coil housing 1. A first magnetic attractor 903 is disposed inside the barrier tube 902. A common flat washer 901 is disposed between the hexagonal nut 6 and the coil housing 1. A second magnetic attractor 904 is slidably connected inside the coil housing 1. A return spring 905 is fixedly connected between the second magnetic attractor 904 and the first magnetic attractor 903. When the connector 5 conducts electrical current, the first magnetic attractor 903 generates a magnetic force to attract the second magnetic attractor 904, causing the valve core body 811 to move. When the power is off, the return spring 905 pushes the second magnetic attractor 904... 4. The valve core body 811 slides inside the valve body 2. The isolation tube 902 has a groove at the corresponding position of the second magnetic attractor 904. The second magnetic attractor 904 slides inside the groove. The isolation tube 902 has a groove at the corresponding position of the second magnetic attractor 904. The second magnetic attractor 904 slides inside the groove and is limited. The second magnetic attractor 904 has a groove at the corresponding position of the return spring 905. The return spring 905 moves inside the groove. The second magnetic attractor 904 has a groove at the corresponding position of the return spring 905, so that the return spring 905 pushes the second magnetic attractor 904 to slide inside the isolation tube 902 more stably.

[0024] When in operation, the connector 5 conducts electrical current, and the first magnetic attractor 903 generates magnetic force to attract the second magnetic attractor 904, which drives the valve core body 811 to move. When the power is off, the reset spring 905 pushes the second magnetic attractor 904 to drive the valve core body 811 to slide inside the valve body 2. The valve core body 811 is pulled by the pin 810 to slide inside the valve body 2. When the valve core body 811 slides to a suitable position inside the valve body 2, the inlet 803 introduces water flow. The water moves inside the valve core body 811 and is discharged through the valve core guide hole 806 and the first outlet 801 and the second outlet 802.

[0025] Through the above steps, the valve core body 811 slides inside the valve body 2, causing the liquid flowing into the inlet 803 to be discharged from the positions corresponding to the first outlet 801 and the second outlet 802 on the valve core body 811. The valve core body 811 is made of metal, and the distance between the valve core body 811 and the valve body 2 is one to two micrometers. This solves the problem that the two-position three-way valve is made of rubber, which causes sealing failure, affects sealing performance, causes deformation or leakage of the sealing surface, and increases costs.
