They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model.

[0037] like Figure 1-Figure 5 As shown, the utility model specifically relates to a three-way clamp tube solenoid valve, comprising a top cover 1, a valve body 7 connected to the top cover 1 and a bottom cover 16 connected to the valve body 7, wherein the lower half of the outer side of the valve body 7 is sleeved with a coil 6 assembly;

[0038] One end of the valve body 7 is provided with an adjusting rod 3, and the other end of the valve body 7 is provided with a pull rod assembly;

[0039] The pull rod assembly includes a spring 8, a rod body 9 connected to the spring 8, and a clamping block 10 provided on the rod body 9. One end of the spring 8 is located in the valve body 7 and abuts against the adjusting rod 3. The rod body 9 is slidably connected to the valve body 7.

[0040] It also includes a three-way assembly disposed in the valve body 7, the three-way assembly includes a Y-shaped three-way hose, the first opening of the Y-shaped three-way hose is defined as the inlet pipeline 151, the second opening is the outlet A pipeline 152, and the third opening is the outlet B pipeline 153, and the clamping block 10 is located between the outlet A pipeline 152 and the outlet B pipeline 153;

[0041] When the solenoid valve is energized, the rod body 9 moves relative to the regulating rod 3 through the valve body 7, and the clamping block 10 clamps the outlet A pipeline 152;

[0042] When the solenoid valve is powered off, the rod body 9 moves away from the adjusting rod 3 through the spring 8 , and the clamping block 10 clamps the outlet B pipeline 153 .

[0043] It should be noted that the top cover 1, the valve body 7 and the bottom cover 16 are assembled and connected in sequence. The coil 6 assembly is sleeved on the surface of the valve body 7, and the coil 6 assembly and the valve body 7 are in the same axial direction. One end of the regulating rod 3 is located in the valve body 7, one end of the rod body 9 is also located in the valve body 7, and the spring 8 is in contact with the end of the regulating rod 3 located in the valve body 7;

[0044] The three-way assembly is assembled in the valve body 7 to ensure the stability of the three-way assembly in the valve body 7, wherein the clamping block 10 located at the other end of the rod body 9 is located between the outlet A pipeline 152 and the outlet B pipeline 153, and the outlet A pipeline 152 and the outlet B pipeline 153 are clamped by the clamping block 10 respectively to realize the rapid switching of the fluid channel.

[0045] An electric pin 2 is provided at one end of the regulating rod 3 away from the coil 6 assembly. When the top cover 1 is covered with the valve body 7 , the electric pin 2 passes through the top cover 1 and extends out of the top cover 1 .

[0046] The details are as follows: when the solenoid valve is energized through the electric pin 2, the coil 6 assembly generates electromagnetic force, and under the action of the electromagnetic force, the rod body 9 moves in the valve body 7, and one end of the rod body 9 located in the valve body 7 moves synchronously toward the regulating rod 3. At this time, the spring 8 connected to the rod body 9 is squeezed and is in a compressed state. During the movement of the rod body 9, the clamping block 10 provided on the rod body 9 moves away from the outlet B pipeline 153 and clamps the outlet A pipeline 152. At this time, the outlet A pipeline 152 is in a closed state, and the outlet B pipeline 153 is in a flowing state;

[0047] When the solenoid valve is in a power-off state, the electromagnetic force generated by the coil 6 assembly is in a failed state. Since the spring 8 is in contact with the adjusting rod 3 and is in a compressed state, the elasticity of the spring 8 is used to drive the rod body 9 to move in the opposite direction. The clamping block 10 provided on the rod body 9 moves away from the outlet A pipeline 152 and clamps the outlet B pipeline 153. At this time, the outlet B pipeline 153 is in a closed state, and the outlet A pipeline 152 is in a flowing state.

[0048] During the operation of the solenoid valve, the position of the adjusting rod 3 does not change, and the pressing force of the spring 8 and the movable clearance of the pull rod are adjusted by the adjusting rod 3 .

[0049] The solenoid valve can generally be switched multiple times within 1 minute depending on the working environment and usage.

[0050] In addition, the adjusting rod 3 is threadedly connected to the valve body 7 , and a person can rotate the adjusting rod 3 to control the movable gap between the adjusting rod 3 and the rod body 9 .

[0051] The Y-type three-way hose 15 is used as a channel for fluid flow. It adopts a Y-type three-way without dead angles to reduce the residual rate of the fluid. Compared with the right-angle three-way, it has a lower fluid residual rate. In addition, the left and right clamp blocks 10 can use only one set of spring 8 system, saving volume and improving reliability.

[0052] In addition, the Y-shaped three-way hose 15 is a Y-shaped rubber hose.

[0053] The three-way assembly also includes an IN interface 14, an OUT interface A11, an OUT interface B13 and two clamping blocks 12, one of the clamping blocks 12 is snap-connected to the IN interface 14 to seal and fix the inlet pipeline 151 to the IN interface 14, and the other clamping block 12 is snap-connected to the OUT interface A11 and the OUT interface B13 respectively to seal and fix the outlet A pipeline 152 to the OUT interface A11, and the outlet B pipeline 153 to the OUT interface B13.

[0054] The IN interface 14, the OUT interface A11 and the OUT interface B13 are all separate entities.

[0055] The IN interface 14 , the OUT interface A11 and the OUT interface B13 are respectively detachably connected to the outer wall of the valve body 7 to seal and fix the Y-shaped three-way hose.

[0056] The IN interface 14, the OUT interface A11 and the OUT interface B13 are separately detachable entities. One end of the IN interface 14 is connected to the inlet pipeline 151, which not only fixes the position of the inlet pipeline 151 in the valve body 7, but also enables external fluid to be introduced into the inlet pipeline 151 through the IN interface 14.

[0057] One end of the OUT interface A11 is connected to the outlet A pipeline 152, which not only fixes the outlet A pipeline 152 at the position of the valve body 7, but also can guide the fluid from the outlet A pipeline 152 into the OUT interface A11 and out of it;

[0058] One end of the OUT interface B13 is connected to the outlet B pipeline 153, which not only fixes the position of the outlet B pipeline 153 at the valve body 7, but also can guide the fluid from the outlet B pipeline 153 into the OUT interface B13 and then guide it out to the outside.

[0059] The IN interface 14 , the OUT interface and the OUT interface B13 are respectively connected to the corresponding pipelines through the clamping block 12 to ensure the sealing of the fluid flowing in or out of the Y-shaped three-way hose 15 , and at the same time, the Y-shaped three-way hose can be stably positioned and connected to the valve body 7 .

[0060] The outer wall of the valve body 7 is provided with a card slot 71 used for matching the IN interface 14, the OUT interface A11 and the OUT interface B13, so that the IN interface 14, the OUT interface A11 and the OUT interface B13 can be detachably connected to the valve body 7 respectively.

[0061] Through the contoured snap-in arrangement, the IN interface 14, the OUT interface A11 and the OUT interface B13 can be quickly disassembled, and the assembly reliability is high.

[0062] The valve body 7 is provided with a slide groove for use with the rod body 9 , and the rod body 9 is slidably connected to the valve body 7 via the slide groove.

[0063] It should be noted that the coil 6 assembly is assembled on the lower half of the outer surface of the valve body 7 and is in the same axial direction as the valve body 7. The end of the rod body 9 away from the adjusting rod 3 is slidably connected to the valve body 7 through a slide groove. The end of the rod body 9 connected to the spring 8 is inserted into the valve body 7 and the spring 8 is abutted against the adjusting rod 3. It can be understood that most of the rod body 9 is located in the valve body 7, and the smaller end is slidably connected to the valve body 7 to play a guiding role.

[0064] Therefore, when the rod body 9 moves linearly in the valve body 7, one end of the rod body 9 moves closer to or farther from the adjusting rod 3. When the rod body 9 moves closer to the adjusting rod 3, the spring 8 is in a compressed state, and the clamping block 10 located on the rod body 9 clamps the outlet A pipeline 152, and the outlet B pipeline 153 is in a flow state.

[0065] When the rod body 9 is away from the adjusting rod 3 , the spring 8 is in a relaxed state, and the clamping block 10 located on the rod body 9 clamps the outlet B pipeline 153 , and the outlet A pipeline 152 is in a flow state.

[0066] The coil 6 assembly includes a coil 6 sleeved on the lower half of the side wall of the valve body 7 and a protective cover 5 sleeved on the surface of the coil 6 .

[0067] Among them, the protective cover 5 is sleeved on the surface of the coil 6 to shield and protect the coil 6 on the surface of the valve body 7. At the same time, one end of the protective cover 5 abuts against the top cover 1, and the other end of the protective cover 5 abuts against the upper half of the valve body 7 to clamp and fix the entire valve body 7.

[0068] The valve body 7 is further provided with magnetic conductive sheets 4. Two groups of magnetic conductive sheets 4 are provided, and the two groups of magnetic conductive sheets 4 are cross-staggeredly arranged in the valve body 7 and located at both ends of the coil 6. The magnetic conductive sheets 4 are used to improve the magnetic circuit and enhance the electromagnetic force.

[0069] The valve body 7 is provided with a positioning hole on the outside, and the bottom cover 16 is provided with an auxiliary hole. The bottom cover 16 is clamped on the valve body 7 and the positioning rod 17 passes through the positioning hole and the auxiliary hole in sequence to fix the bottom cover 16 and the valve body 7.

[0070] The above embodiments are only specific implementation methods of the present invention, which are used to illustrate the technical solution of the present invention rather than to limit it. The protection scope of the present invention is not limited thereto. Although the present invention is described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that any technician familiar with the technical field can still modify the technical solution recorded in the aforementioned embodiments within the technical scope disclosed by the present invention, or can easily think of changes, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not make the essence of the corresponding technical solution deviate from the spirit and scope of the technical solution of the embodiment of the present invention, and should all be covered within the protection scope of the present invention.
