Description

Technical Field

[0001] The utility model relates to the technical field of electric valves, in particular to an electric valve for irrigation with multiple outlets. Background Art

[0002] An electric valve is a valve that is controlled to open or close by an electric device. It is usually used in automation systems, such as industrial control systems, HVAC systems, water treatment systems, etc.

[0003] Electric valves are used in a variety of applications. In the field of irrigation, electric valves are usually used to control the flow of water. In general, they are used in fields. Electric valves are opened or closed according to electrical signals or preset programs. Since the closing or opening is an electrical device, the closing or opening of the electric valve is relatively fast. When closing, the water flow needs to be sealed. Therefore, water may hit the closing part of the electric valve, resulting in a more serious water hammer phenomenon. The water hammer phenomenon may cause the electric valve to shake, thereby causing the connection groove between the electric valve and the external water pipe to loosen, which may cause a waste of water resources.

[0004] In order to solve the above problems, this application proposes a multi-outlet irrigation electric valve. Utility Model Content

[0005] The utility model aims at the technical problems existing in the prior art and provides a multi-outlet irrigation electric valve.

[0006] The utility model provides a technical solution to the above-mentioned technical problems as follows: a multi-outlet irrigation electric valve, comprising a shell, the shell being fixedly connected to a water inlet pipe, the top of the shell being fixedly connected to a motor, the interior of the shell being rotatably connected to a box body, the rotating shaft of the motor passing through the top of the shell and being fixedly connected to the box body, the box body being provided with a first through opening, the shell being provided with a second through opening, the shell being provided with a threaded opening, the shell being detachably connected to a threaded pipe via the threaded opening, the inner wall of the threaded pipe being fixedly connected to a water outlet pipe, and one end of the water outlet pipe located inside the shell being in contact with the outer wall of the box body.

[0007] The shell is fixedly connected to a protective plate through a threaded port, and one side of the protective plate is fitted with one side of the threaded pipe. By providing the protective plate, protection is achieved at the connection between the threaded pipe and the threaded port, preventing water from flowing into the connection between the threaded port and the threaded pipe, thereby preventing long-term erosion from affecting the disassembly and replacement of the water outlet pipe.

[0008] The inner wall of the shell is fixedly connected with a fixing rod, the top of the fixing rod is fixedly connected with a sleeve, the inner wall of the sleeve is fixedly connected with a spring, the bottom end of the spring is fixedly connected with a connecting rod, the end of the connecting rod away from the spring is fixedly connected with a sealing ring, the inner wall of the sealing ring is fitted with the outer wall of the water outlet pipe, and the fixing rod, the connecting rod, the sleeve, the spring and the sealing ring are arranged to achieve sealing at the joint between the water outlet pipe and the box body, thereby preventing water from flowing out through the joint between the water outlet pipe and the box body when not in use, thereby avoiding affecting the control effect of the outlet of the irrigation electric valve.

[0009] A groove is provided on the outer wall of the box body, and the box body is slidably connected with a linkage plate through the groove. One side of the linkage plate is fixedly connected to one end of a fixing rod. By providing the groove and the linkage plate, support for the sealing ring is achieved to prevent the sealing ring from shaking during the sealing at the joint between the water outlet pipe and the box body, thereby avoiding affecting the sealing effect at the joint between the water outlet pipe and the box body.

[0010] The shell is provided with a sealing groove through a threaded opening, the outer wall of the water outlet pipe is fixedly connected with a positioning plate, a side of the positioning plate close to the threaded pipe is fixedly connected with a sealing gasket, one side of the sealing gasket is fitted with the sealing groove provided in the box body, and the positioning and sealing of the water outlet pipe are achieved by arranging the positioning plate, the sealing gasket and the sealing groove, so as to avoid the water outlet pipe from pushing the protective plate too much after the user disassembles and installs the water outlet pipe, thereby avoiding affecting the sealing effect of the electric valve.

[0011] The rotating shaft of the motor is fixedly connected with a positioning piece, and the top of the shell is fixedly connected with a positioning block. The positioning piece and the positioning block are provided to achieve docking between the second port and the water outlet pipe. When the electric valve is initially used, the water outlet pipe can pass through the positioning piece and the positioning block during installation, and the docking status of the water outlet pipe and the second port can be observed, thereby achieving a control effect on the electric valve.

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

[0013] Water is controlled by the coordinated use of the outer shell, the water inlet pipe, the motor, the box, the first port, the second port, the threaded port, the threaded pipe and the water outlet pipe. Water flows into the interior of the box through the water inlet pipe, the first port or the second port, and the water inside the box flows into the interior of the water outlet pipe through the first port or the second port, thereby completing the water guidance. When it is necessary to close some outlets, the box can be rotated by the motor to control the outlets. When some outlets are closed, since the water is inside the outer shell, the water will not be suddenly closed, thereby avoiding the occurrence of water hammer.

[0014] The fixing rod, connecting rod, sleeve, spring and sealing ring cooperate with each other to achieve sealing of the joint between the water outlet pipe and the box body, thereby preventing water from flowing out through the joint between the water outlet pipe and the box body when not in use, thereby avoiding affecting the control effect of the outlet of the irrigation electric valve.

[0030] Working principle:

[0031] For the multi-outlet irrigation electric valve, after the user installs the electric valve to the required position, when the water outlet pipe 9 needs to be controlled, the box body 4 is rotated by the motor 3. When the box body 4 is rotating, one water outlet pipe 9 is docked with a first port 5, thereby achieving the closure of the other two water outlet pipes 9. When two water outlet pipes 9 are docked with two first ports 5, one water outlet pipe 9 can be closed. When the water outlet pipe 9 is not docked with the first port 5 or the second port 6, the water outlet pipe 9 can be closed, thereby achieving individual control of each water outlet pipe 9. At the same time, when the water outlet pipe 9 is closed, the water transported to the inside of the shell 1 will not be suddenly closed, thereby avoiding the occurrence of water hammer, thereby avoiding the loose connection groove at the connection between the electric valve and the external water pipe.
