The waterway solenoid valve includes: a valve body member 1, a control member 2, and the like.
The valve body member 1 has a valve body 11, a valve body inlet flow passage 12, a valve body valve port 13, a valve body outlet flow passage 14, and the like. The valve body valve port 13 is used for separating the valve body inlet flow passage 12 from the valve body outlet flow passage 14. When the valve body valve port 13 is opened, the liquid medium flows through the valve body inlet flow passage 12, the valve body valve port 13 and the valve body outlet flow passage 14 in sequence.
The valve body inlet flow passage 12 includes: an inlet flow passage first section 121, an inlet flow passage middle section 122, and an inlet flow passage last section 123. The inlet runner head section 121 is the inlet of the valve body 11. One end of the inlet flow passage middle section 122 is connected with the inlet flow passage head section 121. The middle of the inlet flow passage middle section 122 is connected with the inlet flow passage end section 123. The opposite end of the inlet flow passage middle section 122 penetrates through the valve body 11 to form a valve body screw. The valve body screw is in threaded connection with a detachable sealing screw plug 3. Referring to fig. 2, a schematic structural view of the sealing plug 3 is shown. The cylindrical filter screen 4 is arranged in the middle section 122 of the inlet flow passage, and the two sections have a common extending direction. Referring to fig. 3, there is shown a schematic structural view of the cylindrical filter screen 4. Opposite ends of the cylindrical filter screen 4 extend to the inlet flow passage first section 121 and the sealing screw plug 3 respectively, so that the liquid medium in the inlet flow passage first section 121 enters the inlet flow passage last section 123 after being filtered by the cylindrical filter screen 4. The mesh diameter of the cylindrical filter screen 4 can be processed according to the actual filter requirement. Preferably, the cylindrical filter screen 4 is made of stainless steel, so that the corrosion resistance is stronger, and the application range of the liquid medium is wider. Preferably, the cylindrical filter screen 4 is formed by punching a plate, so that the strength is higher and the pressure resistance is higher.
The purpose of the cylindrical filter screen 4 is to: the valve body part 1 is added with the function of filtering impurities. Impurities in the liquid medium are blocked by the cylindrical filter screen 4 and remain inside the cylindrical filter screen 4, so that failure of the waterway electromagnetic valve caused by impurity problems is reduced. The cylindrical filter screen 4 adopts a cylindrical structure, so as to increase the flow surface area and save the internal space. In addition, the cylindrical filter screen 4 is independent of the inlet flow passage middle section 122, and an operator can detach the sealing screw plug 3 to replace the cylindrical filter screen 4, so that the maintenance is convenient at regular intervals.
In one embodiment, the inlet flow path head section 121 forms an angle with the inlet flow path intermediate section 122. The aim of setting the included angle is that: the liquid medium passing through the cylindrical filter screen 4 is ensured to have enough flow, and the flow requirement of the design of the waterway electromagnetic valve is met. Preferably, the first inlet channel section 121 extends horizontally, the middle inlet channel section 122 extends obliquely downward by 45 °, and the last inlet channel section 123 extends vertically.
In one embodiment, a sealing ring 5 made of rubber is arranged between the sealing screw plug 3 and the valve body screw, so that the risk of liquid leakage of the valve body screw is reduced. Referring to fig. 4, a schematic structural view of the seal ring is shown.
The control part 2 is used for selectively closing or opening the valve body valve port 13 of the valve body part 1.
In an embodiment, the control part 2 has a vertical sleeve 21, a fixed upper core 22, a movable lower core 23, a sealing valve plug 24, a return spring 25, a solenoid 26, etc. The fixed upper iron core 22, the movable lower iron core 23 and the sealing valve plug 24 are arranged in the vertical sleeve 21. The fixed upper core 22 is fixed. The movable lower iron core 23 is below the fixed upper iron core 22 and is displaceable up and down along the vertical sleeve 21. The sealing valve plug 24 is fixed at the bottom of the movable lower iron core 23 and is downward opposite to the valve port 13 of the valve body.

The return spring 25 is always in a compressed state. The electromagnetic coil 26 is arranged outside the vertical sleeve 21. When the electromagnetic coil 26 is not powered on, the sealing valve plug 24 closes the valve opening 13 of the valve body under the action of the elastic force of the return spring 25, and at this time, a space is formed between the fixed upper iron core 22 and the movable lower iron core 23. When the electromagnetic coil 26 is powered on, the fixed upper iron core 22 attracts the movable lower iron core 23, the movable lower iron core 23 moves upwards and drives the sealing valve plug 24 to overcome the elastic force of the return spring 25 to open the valve opening 13 of the valve body. The operating principle of the control part 2 is as follows: the electromagnetic coil 26 is not powered initially, the sealing valve plug 24 closes the valve body valve port 13 under the elastic force of the return spring 25, and the valve body inlet flow passage 12 and the valve body outlet flow passage 14 are not communicated. If receiving the opening signal of the valve opening 13, the electromagnetic coil 26 is electrified, the fixed upper iron core 22 attracts the movable lower iron core 23, the movable lower iron core 23 moves upwards and drives the sealing valve plug 24 to open the valve opening 13 against the elastic force of the return spring 25, and at this time, the valve inlet runner 12 is in communication with the valve outlet runner 14. If the opening signal of the valve body valve port 13 stops, the electromagnetic coil 26 is not electrified, the sealing valve plug 24 is reset under the action of the elastic force of the reset spring 25, and the valve body valve port 13 is closed again.
The foregoing has outlined rather broadly the more detailed description of the utility model in order that the detailed description thereof that follows may be better understood, and in order that the present utility model may be better understood. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
