Description
Technical Field
The invention relates to an electromagnetic valve, in particular to a sliding vane type three-way electromagnetic valve.
Background
Fig. 1 and 2 are schematic sectional views showing a conventional sliding-vane three-way solenoid valve. As shown in fig. 1 and 2, the sliding-vane three-way electromagnetic valve comprises a valve body 1a, a sealing seat 2a, a valve core assembly and an electromagnetic driving assembly.
The valve body 1a has a valve chamber 10a, an inlet 13a, a first outlet 11a, and a second outlet 12a. The inlet 13a, the first outlet 11a, and the second outlet 12a are respectively communicated with the valve chamber 10 a. The seal seat 2a is fixedly provided in the valve chamber 10a and shields the first outlet 11a and the second outlet 12a. The seal seat 2a is provided with a first valve port 21a communicating with the first outlet 11a and a second valve port 22a communicating with the second outlet 12a. In the example of fig. 1 and 2, the number of the first ports 21a and the second ports 22a is two, the two first ports 21a are arranged up and down, and the two second ports 22a are arranged up and down.
The valve element assembly is arranged in the valve chamber 10a and is movable in the axial direction Z of the valve body 1a between a first position and a second position under the drive of the electromagnetic drive assembly. The valve core assembly comprises a push rod 31a, a positioning sleeve 32a, a spring seat 33a and a sliding sheet 34a matched with the sealing seat 2a. The spring seat 33a and the positioning sleeve 32a are respectively riveted with the ejector rod 31a, and the positioning sleeve 32a drives the sliding sheet 34a to move together. Wherein the spring seat 33a is a magnetically conductive material, and generates magnetism in a magnetic field. The slide 34a is provided with two first openings 341a that are respectively engaged with the two first valve ports 21a, and one second opening 342a that is engaged with the second valve port 22a above (here, "above" is with respect to the other second valve port 22 a).
The electromagnetic drive assembly includes an electromagnetic coil 41a, a bobbin 42a, an iron core 43a, and a spring 44a. The iron core 43a is a magnetic conductive material, and is fixed to the casing 5a of the three-way electromagnetic valve by caulking, and is not movable.
When the electromagnetic coil 41a is not energized, the valve core assembly is in the first position, as shown in fig. 1, the entity of the sliding vane 34a blocks the two second valve ports 22a, the fluid flowing in from the inlet 13a cannot flow out through the second outlet 12a, and the two first openings 341a of the sliding vane 34a are respectively opposite to the two first valve ports 21a in a one-to-one correspondence manner, and the fluid flowing in from the inlet 13a can flow out through the first outlet 11 a.
When the electromagnetic coil 41a is energized, the magnetic field generated by it generates a suction force between the spring seat 33a and the iron core 43a, which is greater than the elastic force generated by the spring 44a. Since the core 43a is stationary, the spool assembly will move upward until it comes into contact with the core 43a and stops, at which point the spool assembly is in the second position, as shown in fig. 2. When the valve cartridge assembly is in the second position, the body of the slide 34a blocks the first valve port 21a, fluid flowing in from the inlet 13a cannot flow out through the first outlet 11a, the second opening 342a of the slide 34a faces the second valve port 22a above the seal seat 2a, and fluid flowing in from the inlet 13a can flow into the second outlet 12a through both the second valve ports 22a because the bottom of the slide 34a is higher than the second valve port 22a below the seal seat 2a.
The slide 34a and the seal seat 2a are usually made of stainless steel, and it is difficult to achieve tight adhesion between the two, so that leakage of fluid easily occurs, and fluid passes through an outlet which should be closed, thereby affecting the operation of the three-way electromagnetic valve.

Detailed Description
The invention is further described below with reference to the accompanying drawings.
Please refer to fig. 3 to 8. The sliding vane type three-way electromagnetic valve comprises a valve body 1, a sealing seat 2, a valve core assembly and an electromagnetic driving assembly.
The valve body 1 has a valve chamber 10, an inlet 13, a first outlet 11 and a second outlet 12. The inlet 13, the first outlet 11 and the second outlet 12 are respectively communicated with the valve chamber 10. In the present embodiment, the valve body 1 has a first side and a second side opposite to each other, the inlet 13 is provided at the first side of the valve body 1, and the first outlet 11 and the second outlet 12 are provided at the second side of the valve body 1.
The sealing seat 2 is fixedly arranged in the valve cavity 10 and shields the first outlet 11 and the second outlet 12. The sealing seat 2 is provided with a first valve port 21 communicated with the first outlet 11 and a second valve port 22 communicated with the second outlet 12.
The valve core assembly is arranged in the valve cavity 10 and can move along the axial direction of the valve body 1 between a first position and a second position under the drive of the electromagnetic drive assembly. The valve core assembly comprises a push rod 31, a positioning piece 32, a spring seat 33 and a valve core matched with the sealing seat 2.
In this embodiment, the valve core includes a first slide 34, an elastic seal 35, and a second slide 36. The first sliding vane 34 is disposed between the elastic sealing member 35 and the sealing seat 2, and the first sliding vane 34 is provided with a first opening 341 matched with the first valve port 21 and a second opening 342 matched with the second valve port 22. The elastic sealing member 35 is disposed on a side of the first sliding sheet 34 opposite to the sealing seat 2, and the elastic sealing member 35 is provided with a first through hole 351 corresponding to the first opening 341 and a second through hole 352 corresponding to the second opening 342. The elastic sealing member 35 is provided with a first boss 355 corresponding to the first valve port 21 and a second boss 356 corresponding to the second valve port 22 on a side facing the first slider 34. The first slider 34 is provided with a first boss hole 345 corresponding to the first boss 355 and a second boss hole 346 corresponding to the second boss 356, and each boss passes through the corresponding boss hole and abuts against the seal seat 2. The elastic sealing member 35 has elasticity, and the protruding portion thereof generates deformation under the action of fluid pressure, so that the protruding portion is closely attached to the sealing seat 2, and a more ideal sealing effect can be achieved. Optionally, each protruding part and the corresponding protruding part perforation always keep an interference fit state, and the protruding parts have certain elasticity, so that the two are tightly matched. Since the plurality of protrusions of the elastic sealing member 35 pass through the first slider 34, the elastic sealing member 35 can move together with the first slider 34. In addition, the first sliding sheet 34 reduces the contact area between the elastic sealing element 35 and the sealing seat 2, reduces the friction resistance of the elastic sealing element 35 during movement, and also reduces the abrasion of the elastic sealing element 35.
Optionally, the periphery of the side of the first slider 34 facing the elastic sealing member 35 is provided with a chamfer 348, so that the elastic sealing member 35 is prevented from being scratched by the sharp edge of the first slider 34.
Optionally, the first protruding portion 355 has a first cavity 355a, the second protruding portion 356 has a second cavity 356a, and both the first cavity 355a and the second cavity 356a are open on a side of the elastic sealing member 35 facing away from the first slider 34.
The second sliding vane 36 is disposed on a side of the elastic sealing member 35 opposite to the first sliding vane 34, and the second sliding vane 36 is provided with a first opening 361 corresponding to the first through hole 351 of the elastic sealing member 35, a second opening 362 corresponding to the second through hole 352 of the elastic sealing member 35, a first through hole 365 corresponding to the first cavity 355a of the first protrusion, and a second through hole 366 corresponding to the second cavity 356a of the second protrusion. The first opening 341, the first through hole 351, the first opening 361, the second opening 342, the second through hole 352, and the second opening 362 function to form a fluid circulation channel. The through-flow hole is used for enabling the fluid to flow into the cavity of the protruding part, so that the top surface of the protruding part can be tightly attached to the sealing seat 2 under the action of the fluid pressure to seal the flow channel. Since the elastic seal member 35 has elasticity and is provided with the cavity of the boss, the boss provided with the cavity can easily generate a required deformation amount under the action of pressure, and further, the boss can be tightly attached to the seal seat 2 even under a smaller pressure difference, so that a more ideal sealing effect can be obtained.
Optionally, the materials of the first sliding piece 34, the second sliding piece 36 and the sealing seat 2 are metal and plastic, the metal material is preferably stainless steel or aluminum, the plastic material is preferably wear-resistant plastic, the material of the elastic sealing piece 35 is a material which deforms under the action of fluid pressure, preferably rubber and elastic cloth, more preferably rubber, and when the material of the elastic sealing piece 35 is elastic cloth, the cloth is preferably subjected to anti-leakage treatment.
The number of first ports 21 and the number of second ports 22 may be one or more. In the example shown in the figure, the number of the first ports 21 and the second ports 22 is two, and the two first ports 21 are arranged up and down, and the two second ports 22 are arranged up and down. The first slider 34 is provided with two first openings 341 corresponding to the two first valve ports 21 one by one and one second opening 342 corresponding to the second valve port 22 above. The elastic sealing member 35 is provided with two first protrusions 355 corresponding to the two first valve ports 21 one by one, respectively, and two second protrusions 356 corresponding to the two second valve ports 22 one by one, respectively. The second slide 36 is provided with two first through holes 365 corresponding to the first cavities 355a of the two first protruding portions one by one and two second through holes 366 corresponding to the second cavities 356a of the two second protruding portions one by one.
The positioning member 32 is connected to the ejector rod 31, the second slide 36, the elastic sealing member 35, and the first slide 34, respectively. More specifically, the second slider 36 is provided with a third opening 363, the elastic seal member 35 is provided with a third through hole 353 corresponding to the third opening 363, and the first slider 34 is provided with a third opening 343 corresponding to the third through hole 353. The positioning piece 32 is a positioning sleeve sleeved outside the ejector rod 31. The top end of the positioning sleeve 32 is provided with a circle of flange 321 extending along the radial direction, and a part of the flange 321 is sequentially inserted into the third opening 363, the third opening 353 and the third opening 343, so that the ejector rod 31 can drive the first sliding vane 34, the elastic sealing member 35 and the second sliding vane 36 to move together. The spring seat 33 is located above the positioning sleeve 32, and the spring seat 33 is made of a magnetic conductive material and generates magnetism in a magnetic field. In the present embodiment, the spring seat 33 and the positioning sleeve 32 are respectively riveted with the jack 31. The third apertures 363, 353 and 343 are shaped in an asymmetric configuration, which may act as an error proofing during the manufacturing process.
The electromagnetic drive assembly includes an electromagnetic coil 41, a bobbin 42, an iron core 43, and a spring 44. The electromagnetic coil 41 is wound around the outer peripheral surface of the bobbin 42, the bobbin 42 is provided with a center hole 420 extending in the axial direction, and the iron core 43 is at least partially disposed in the center hole 420 of the bobbin. An axially extending slot is formed in a surface of the iron core 43 facing the ejector rod, and a spring stop portion 45 for axially limiting the spring 44 is arranged in the slot 430. One end of the jack 31 extends into the slot 430. The spring 44 is fitted over the jack 31, one end of the spring 44 abuts against the spring seat 33, and the other end abuts against the spring stopper 45.
In this embodiment, the sidewall of the slot 430 is provided with an annular step 431. The spring stopper 45 is a stop sleeve disposed in the slot 430. One end of the stop collar 430 abuts against the annular step 431, and the other end abuts against one end of the spring 44. One end of the push rod 31 passes through the stop collar 431.
When the solenoid 41 is not energized, the spool assembly is in the first position, as shown in fig. 3 and 4, the two second protrusions 356 of the elastic seal 35 respectively block the two second valve ports 22, the fluid flowing in from the inlet 13 cannot flow out through the second outlet 12, and the two first openings 341 of the first slider 34 respectively face the two first valve ports 21 in a one-to-one correspondence, and the fluid flowing in from the inlet 13 can flow into the first outlet 11 through the two first valve ports 21.
When the solenoid 41 is energized, the valve element assembly moves upward to the second position, as shown in fig. 5, with the seal housing 2 held stationary. When the valve cartridge assembly is in the second position, the two first protrusions 355 of the elastic seal member 35 respectively block the two first valve ports 21, the fluid flowing in from the inlet 13 cannot flow out through the first outlet 11, the second opening 342 of the first slide 34 faces the second valve port 22 above the seal seat 2, and the fluid flowing in from the inlet 13 can flow into the second outlet 12 through the two second valve ports 22 because the bottom of the first slide 34 is higher than the second valve port 22 below the seal seat 2.
When the fluid flows into the inlet 13, the first side (left side in the drawing) of the elastic sealing member 35 is a high pressure area, and the second side (right side in the drawing) is a low pressure area, and under the pressure difference between the first side and the second side, the elastic sealing member 35 is pressed against the sealing seat 2, so as to obtain a good sealing effect. In addition, since the respective convex portions of the elastic seal member 35 are always depressed at the portions contacting the inlet of the passage due to the impact force of the fluid, the peripheral portions tend to be raised, and the peripheral portions are raised to further promote the depression of the convex portions, once the convex portions are depressed too much, the resistance to sliding on the seal holder 2 becomes very large, and thus it is necessary to restrict the entire deformation of the elastic seal member 35. The second slide 36 may act to compress the elastic seal 35 against the first slide 14 under the action of fluid pressure, thereby limiting the overall deformation of the elastic seal 35. To reduce product costs, the second slider 36 may be configured exactly as the first slider 34.
In the sliding vane type three-way electromagnetic valve provided by the embodiment of the invention, the plurality of protruding parts of the elastic sealing piece penetrate through the first sliding vane and block the corresponding valve port. This arrangement allows the resilient seal to move along with the first slide, and the pressure exerted by the fluid in the valve chamber against the plurality of bosses ensures that the bosses abut against the valve port, thereby providing a reliable fluid seal in a soft seal.
It will be apparent to those skilled in the art that various modifications and variations can be made to the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
