Abstract
Description
Technical Field
[0001] This utility model is a timed drain valve coil, belonging to the field of drain valve technology. Background Technology
[0002] Electromagnetic drain valves control the opening and closing of the valve core through electromagnetic force, thereby achieving fluid discharge. Common types include direct-acting and pilot-operated solenoid valves. When a normally closed solenoid valve is energized, the electromagnetic coil generates electromagnetic force, lifting the valve core and opening the valve to allow fluid to drain. When de-energized, the electromagnetic force disappears, and the spring presses the valve core back onto the valve seat, closing the valve and stopping fluid flow. However, existing electromagnetic drain valves generate heat in the coil when energized for extended periods, causing a decrease in the magnetism of the electromagnetic components, resulting in poor practicality. Furthermore, they lack a timed drainage function. There is an urgent need for a timed drain valve coil to address these issues. Utility Model Content
[0003] To address the shortcomings of existing technologies, the purpose of this invention is to provide a timed drain valve coil to solve the problems mentioned in the background section. This invention has a reasonable structure and uses a limiting block to fix the position of the first adsorption iron block, so that the first electromagnet and the second electromagnet only need to be energized for a short time to complete the on / off switching of the valve body. This saves energy and has strong reliability and practicality.
[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a timed drain valve coil, including a valve body, a water inlet, a drain outlet, a control panel, a valve plate, a first adsorption iron block, a first electromagnet, a limit block, and a second electromagnet. The water inlet is welded to the left end face of the valve body, and the drain outlet is welded to the right end face of the valve body. A control panel is installed on the outer side of the valve body. A valve plate is provided inside the valve body. A first adsorption iron block is provided above the valve plate. A first electromagnet is provided above the first adsorption iron block. A limit block is provided inside the valve body, and a second electromagnet is provided outside the limit block.
[0005] Furthermore, a movable seat is welded to the upper surface of the valve plate, the movable seat slides tightly along the inner wall of the valve body, a first connecting rod is fixed to the upper surface of the movable seat, and the movable seat is fixedly connected to the lower surface of the first adsorption iron block through the first connecting rod.
[0006] Furthermore, a partition is provided inside the valve body, and a through hole is provided on the surface of the partition. The first connecting rod passes through the partition through the through hole, and a return spring is sleeved on the outer side of the first connecting rod. The two ends of the return spring abut against the upper end face of the movable seat and the lower end face of the partition, respectively.
[0007] Furthermore, a sliding groove is provided inside the valve body, and the limiting block slides tightly along the inner wall of the sliding groove. A second adsorption iron block is provided inside the sliding groove, and the limiting block and the second adsorption iron block are fixedly connected by a second connecting rod.
[0008] Furthermore, the lower end of the limiting block is arc-shaped, and a compression spring is provided on the inner side of the limiting block. Two sets of compression springs of the same specifications are provided, and the two ends of the compression springs respectively abut against the limiting block and the inner wall of the sliding groove.
[0009] Furthermore, the first electromagnet is electrically connected to the control panel via a wire, and when the first electromagnet is energized, it attracts the first adsorbed iron block. The second electromagnet is electrically connected to the control panel via a wire, and when the second electromagnet is energized, it attracts the second adsorbed iron block.
[0010] Furthermore, a pressure detector is installed inside the water inlet, and the pressure detector is electrically connected to the control panel via a wire. The control panel has a built-in timing module, and a guide mark is provided on the outer side of the valve body.
[0011] The beneficial effects of this utility model are as follows: The timed drainage valve coil of this utility model incorporates a first electromagnet, a first adsorption iron block, a second electromagnet, a second adsorption iron block, and a limiting block. When the preset drainage time is reached, the control panel activates the first electromagnet, which attracts the first adsorption iron block. This causes the first adsorption iron block to move upwards along with the moving seat and valve plate via the first connecting rod, compressing the return spring. Simultaneously, one end of the limiting block abuts against the lower surface of the first adsorption iron block, thus limiting its position. Afterward, the first electromagnet is de-energized, and the valve plate is no longer closed, allowing normal liquid flow on both sides of the valve body. When the drainage time ends, the second electromagnet briefly opens, causing the limiting block to retract into the sliding groove and release its position relative to the first adsorption iron block, allowing the valve plate to close again.

Detailed Implementation
[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0020] Please see Figures 1-5 This utility model provides a technical solution: a timed drain valve coil, including a valve body 1, an inlet 2, a drain outlet 3, a control panel 4, a valve plate 5, a first adsorption iron block 6, a first electromagnet 7, a limit block 8, and a second electromagnet 9. The inlet 2 is welded to the left end face of the valve body 1, and the drain outlet 3 is welded to the right end face of the valve body 1. The control panel 4 is installed on the outer side of the valve body 1. The valve plate 5 is set inside the valve body 1. The first adsorption iron block 6 is set above the valve plate 5. The first electromagnet 7 is set above the first adsorption iron block 6. The limit block 8 is set inside the valve body 1. The second electromagnet 9 is set outside the limit block 8. This design solves the problem that the original electromagnetic drain valve loses its magnetism after being energized for a long time and does not have a timed drain function.
[0021] As the first embodiment of this utility model: A movable seat 51 is welded to the upper end face of the valve plate 5. The movable seat 51 slides tightly along the inner wall of the valve body 1. A first connecting rod 63 is fixed to the upper end face of the movable seat 51. The movable seat 51 is fixedly connected to the lower end face of the first adsorption iron block 6 through the first connecting rod 63. The movable seat 51 can drive the valve plate 5 to move together. The first adsorption iron block 6 can drive the movable seat 51 to move together through the first connecting rod 63. A partition 62 is provided inside the valve body 1. A passage is opened on the surface of the partition 62. Hole 621, the first connecting rod 63 passes through the partition 62 through the through hole 621. A return spring 61 is sleeved on the outer side of the first connecting rod 63. The two ends of the return spring 61 abut against the upper end face of the moving seat 51 and the lower end face of the partition 62, respectively. The return spring 61 can help the moving seat 51 to return to its original position. A sliding groove 83 is opened inside the valve body 1. The limiting block 8 slides tightly along the inner wall of the sliding groove 83. A second adsorption iron block 82 is set inside the sliding groove 83. The limiting block 8 and the second adsorption iron block 82 are connected. The two are fixedly connected by a second connecting rod 81. The second adsorption iron block 82 can drive the limit block 8 to move together through the second connecting rod 81. The lower end of the limit block 8 is arc-shaped. A compression spring 84 is provided on the inner side of the limit block 8. Two sets of compression springs 84 are provided. The two ends of the compression spring 84 abut against the limit block 8 and the inner wall of the sliding groove 83, respectively. The first electromagnet 7 is electrically connected to the control panel 4 through a wire. After the first electromagnet 7 is energized, it attracts the first adsorption iron block 6. The second electromagnet 9 is electrically connected to the control panel 4 through a wire. After the second electromagnet 9 is energized, it attracts the second adsorption iron block 82. The control panel 4 can control the opening and closing of the first electromagnet 7 and the second electromagnet 9, respectively. A pressure detector 21 is installed inside the water inlet 2. The pressure detector 21 is electrically connected to the control panel 4 through a wire. The control panel 4 has a built-in timer module. A guide mark 11 is opened on the outer side of the valve body 1. The guide mark 11 makes it easy for users to identify the water inlet 2 and the drain outlet 3.
[0022] As a second embodiment of this utility model: the user correctly connects the inlet 2 and outlet 3 to the external pipe, and then sets a timer via the control panel 4. When the drainage time has not been reached, both the first electromagnet 7 and the second electromagnet 9 are de-energized, and the valve plate 5 remains closed, preventing liquid flow on both sides of the valve body 1. When the preset drainage time is reached, the control panel 4 controls the first electromagnet 7 to open, which in turn attracts the first adsorption iron block 6, causing the first adsorption iron block 6 to move the moving seat 51 and the valve plate 5 together via the first connecting rod 63. The valve moves upward and compresses the return spring 61. At the same time, one end of the limiting block 8 abuts against the lower end of the first adsorbed iron block 6, thereby limiting the first adsorbed iron block 6. Then the first electromagnet 7 is de-energized. At this time, the valve plate 5 no longer remains closed, and the liquid on the left and right sides of the valve body 1 can flow normally. When the drainage time ends, the second electromagnet 9 is briefly opened, thereby generating an attraction force on the second adsorbed iron block 82, causing the limiting block 8 to retract into the sliding groove 83 and release the limitation on the first adsorbed iron block 6. Then the first adsorbed iron block 6 is reset under the action of the return spring 61, causing the valve plate 5 to close again.
[0023] It should be noted that a pressure sensor is installed on one side of the inlet 2 in this design, which can detect the water pressure at one end of the inlet 2. This allows the control panel 4 to determine whether drainage is needed based on the water pressure, in addition to timing. At the same time, a wireless communication module can be installed inside the control panel 4, so that users can control it on a mobile phone or mobile device.
