Description

Technical Field

[0001] The utility model relates to the technical field of solenoid valves, in particular to a solar solenoid valve. Background Art

[0002] A solar solenoid valve is a basic automation component that uses electromagnetic principles to control the flow of fluids (primarily water in solar systems). Its operating principle is based on electromagnetic induction. When energized, the coil inside the solenoid valve generates a magnetic field, which drives the valve core, thereby changing the valve's on / off state.

[0003] In existing solar solenoid valves, both ends of the solenoid valve are usually connected to the water pipe through a threaded connection. During the installation process, it requires certain skills and experience to ensure the accuracy and tightness of the threaded connection. If the threads are not aligned and are forcibly tightened, the threads may be damaged, resulting in a loose connection or leakage. When the solenoid valve needs to be disassembled for repair or replacement, the threaded connection may become stuck due to long-term use. This is because the metal threads oxidize and rust in a humid environment, or because impurities in the water are deposited in the thread gaps, which increases the friction between the threads and makes it difficult to disassemble.

[0004] For this purpose, a solar electromagnetic valve is proposed. Utility Model Content

[0005] The purpose of the present invention is to solve the problem that during the installation process, it requires certain skills and experience to ensure the accuracy and tightness of the threaded connection. When the solenoid valve needs to be disassembled for repair or replacement, the threaded connection may become stuck due to long-term use. The present invention provides a solar solenoid valve.

[0006] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0007] A solar solenoid valve comprises a solenoid valve body and a local water heater connecting pipe, the surface of the solenoid valve body being provided with a limit assembly for docking the solenoid valve body with the water heater pipe, the surface of the limit assembly being provided with a groove, the surface of the solenoid valve body being provided with a clamping assembly for docking the solenoid valve body with the water heater pipe, the surface of the local water heater connecting pipe being provided with a limit groove, the end face of the local water heater connecting pipe being provided with a sealing assembly for sealing the connection between the solenoid valve body and the local water heater connecting pipe, the inner wall of the solenoid valve body being provided with a docking assembly for sealing the connection between the solenoid valve body and the local water heater connecting pipe, and the surface of the solenoid valve body being provided with a sewage pipe structure.

[0008] Furthermore, the limit assembly includes a ring, the surface of the solenoid valve body is fixedly sleeved with a ring, the surface of the ring is fixedly connected to a spring, the end of the spring away from the ring is fixedly connected to a connecting sleeve, and the inner wall of the connecting sleeve is in contact with the surface of the ring, and a groove is opened on the inner wall of the connecting sleeve.

[0009] Furthermore, the clamping assembly includes a special-shaped hole, and the special-shaped hole is opened through the surface of the solenoid valve body. A limiting bead is embedded in the inner wall of the special-shaped hole, and the limiting bead is clamped with the limiting groove.

[0010] Furthermore, the sealing assembly includes a sealing ring, a sealing ring is fixedly connected to the side of the local water heater connecting pipe, and a plug-in ring is fixedly plugged into the inner wall of the local water heater connecting pipe.

[0011] Furthermore, the docking assembly includes a connector, the inner wall of the solenoid valve body is fixedly plugged with the connector, and the surface of the plug-in ring fits the inner wall of the connector, a sealing groove is opened on the side of the connector, and the sealing ring is plugged into the sealing groove.

[0012] Furthermore, there are multiple limiting beads, and the multiple limiting beads are distributed in a circular array on the solenoid valve body.

[0013] The beneficial effects of the utility model are as follows:

[0014] When the two ends of the utility model are connected to the water pipes, the ends adopt a pipeline design and are used in conjunction with the local water heater connection pipe. The solenoid valve body is provided with a limit component. During installation, the installer moves the connecting sleeve, and the inner wall of the connecting sleeve leaves the surface of the limit bead, so that the limit bead can move in the special-shaped hole. Then the local water heater connection pipe can be aligned with the interior of the solenoid valve body and inserted. Then the connecting sleeve is released, and the rebound force of the spring drives the connecting sleeve to move to the original position. When the connecting sleeve moves, it squeezes the limit bead, so that a part of the limit bead moves into the limit groove on the surface of the local water heater connection pipe. At this time, multiple limit beads distributed in a circular array can be stuck in the limit groove. In the process, the inner wall of the connecting sleeve squeezes and limits the limiting bead, so that the limiting bead is stably stuck in the limiting groove. After the local water heater connecting pipe is fully inserted into the interior of the solenoid valve body, the connection between the solenoid valve body and the local water heater connecting pipe is sealed through the setting of the sealing component on the local water heater connecting pipe and the internal docking component of the solenoid valve body. When the solenoid valve body needs to be disassembled, similarly, it is only necessary to operate the limiting component at this time, so that the local water heater connecting pipe can be directly pulled out; the goal of facilitating the disassembly and assembly of the solenoid valve is achieved, and the sealing of the connection can be guaranteed, avoiding the problem that the solenoid valve with threaded connection is more inconvenient during disassembly and assembly.

[0025] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5As shown, a solar solenoid valve includes a solenoid valve body 1 and a local water heater connecting pipe 2. The surface of the solenoid valve body 1 is provided with a limit component 3 for connecting the solenoid valve body 1 with the water heater pipe. The surface of the limit component 3 is provided with a groove 4. The surface of the solenoid valve body 1 is provided with a clamping component 5 for connecting the solenoid valve body 1 with the water heater pipe. The surface of the local water heater connecting pipe 2 is provided with a limit groove 6. The end surface of the local water heater connecting pipe 2 is provided with a sealing component 7 for sealing the connection between the solenoid valve body 1 and the local water heater connecting pipe 2. The inner wall of the solenoid valve body 1 is provided with a docking component 8 for sealing the connection between the solenoid valve body 1 and the local water heater connecting pipe 2. The surface of the magnetic valve body 1 is provided with a sewage pipe structure 9; specifically, the solar solenoid valve adopts a pipeline design at both ends when installed with the water pipe. A limit component 3 is provided on the solenoid valve body 1. When connected, the limit component 3 is moved so that the components in the clamping component 5 can be movable, and then the local water heater connecting pipe 2 can be inserted and connected. The setting of the upper limit groove 6 on the local water heater connecting pipe 2, after the local water heater connecting pipe 2 is fully inserted into the interior of the solenoid valve body 1, the limit component 3 is released at this time, and the components of the clamping component 5 are pressurized so that the components of the clamping component 5 are clamped into the limit groove 6. At the same time, the clamping component 5 is squeezed by the limit component 3. The parts of the component 5 will not move, and the local water heater connecting pipe 2 will be clamped and limited in the solenoid valve body 1. At this time, the local water heater connecting pipe 2 can be quickly inserted and connected. After the local water heater connecting pipe 2 is inserted into the solenoid valve body 1, the sealing component 7 on the local water heater connecting pipe 2 cooperates with the docking component 8 in the solenoid valve body 1 to seal the connection between the local water heater connecting pipe 2 and the solenoid valve body 1, thereby ensuring the sealing of the connection between the solenoid valve body 1 and the local water heater connecting pipe 2. When disassembly is required, only the limiting component 3 needs to be operated to pull the local water heater connecting pipe 2 out of the solenoid valve body 1. The setting of the solenoid valve body 1 is required to provide solar energy. When the water heater is replenished with water, the control system energizes the solenoid valve, the valve core opens, and the water in the water pipe can enter the water tank of the solar water heater. When the water in the water tank reaches the set water level, the control system cuts off the power supply of the solenoid valve, the magnetic field disappears, and the valve core returns to its original position under the action of a spring or other reset device, closing the water channel and stopping water replenishment. The sewage pipe structure 9 is set, and the inner wall of the sewage pipe structure 9 is plugged with a filter structure to filter impurities. The bottom cap can be unscrewed to discharge impurities filtered during use, thereby achieving the goal of facilitating disassembly and assembly of the solenoid valve.

The design of the spring 302 can automatically restore the connecting sleeve 303 to its original position, and the design of the slot 4 cooperates with the movement of the components of the snap-fit assembly 5.

At this time, the connecting sleeve 303 squeezes the internal spring 302 when moving. At this time, the inner wall of the connecting sleeve 303 leaves the surface of the limiting bead 502, so that the limiting bead 502 can move in the special-shaped hole 501, and then the local water heater connecting pipe 2 can be aligned with the interior of the solenoid valve body 1 and inserted. During the insertion process, a part of the limiting bead 502 will move Into the slot 4, at this time, you only need to directly insert the local water heater connecting pipe 2. After the local water heater connecting pipe 2 is completely inserted into the interior of the solenoid valve body 1, loosen the connecting sleeve 303, and the rebound force of the spring 302 drives the connecting sleeve 303 to move to its original position. When the connecting sleeve 303 moves, it squeezes the limiting bead 502, so that a part of the limiting bead 502 moves into the limiting groove 6 on the surface of the local water heater connecting pipe 2. At this time, multiple limiting beads 502 distributed in a circular array can be stuck in the limiting groove 6, and at the same time, the inner wall of the connecting sleeve 303 squeezes and limits the limiting bead 502, so that the limiting bead 502 is stably stuck in the limiting groove 6. At this time, the local water heater connecting pipe 2 can be stably plugged into the local water heater connecting pipe 2.

After the sealing ring 701 is inserted into the sealing groove 802, the sealing ring 701 and the sealing groove 802 can be further sealed, thereby ensuring the sealing between the solenoid valve body 1 and the local water heater connecting pipe 2. At the same time, the surface of the plug-in ring 702 fits with the inner wall of the connector 801, thereby sealing the connection between the solenoid valve body 1 and the local water heater connecting pipe 2.

[0030] like Figure 4 As shown, there are multiple limiting beads 502, and the multiple limiting beads 502 are distributed in a circular array on the solenoid valve body 1; specifically, the multiple limiting beads 502 distributed in a circular array cooperate with the limiting groove 6, so that the clamping between the solenoid valve body 1 and the local water heater connecting pipe 2 can be more stable.

[0031] In summary: When the two ends of the solar solenoid valve are connected to the water pipe, the end portion adopts a pipeline design, and is used in conjunction with the local water heater connecting pipe 2.
