It is understood that the port 11 of the valve housing 10 may be in communication with an external pipe, and the external pipe is filled with fluid, so that the fluid can enter the fluid valve 100 from the port 11 or flow out from the fluid valve 100 to discharge or suck the fluid to the outside from the fluid valve 100, wherein the fluid may be water or antifreeze or other liquid, which is not limited herein.

Alternatively, as shown in fig. 1-3, the valve housing 10 is provided with mounting plates 13, i.e., the valve housing 10 may be connected to other structures via the mounting plates 13 to facilitate securing the valve housing 10 and to enhance the structural stability of the valve housing 10.

The valve core 20 is rotatably installed in the valve housing 10, the valve core 20 may be configured in a column shape, and the valve core 20 includes a connecting shaft 21 and a body 22, an axis of the connecting shaft 21 coincides with an axis of the body 22 and is connected with the body 22, wherein the connecting shaft 21 is connected with the motor power of the electric control device 60 through the hole 12, so as to control the rotation of the connecting shaft 21 through the electric control device 60, and then the connecting shaft 21 drives the body 22 to rotate along the axis of the connecting shaft 21 in the valve housing 10, so as to guide the flow of the fluid in the valve housing 10.

Preferably, an annular protrusion 121 is provided at an edge of the valve housing 10, which extends through the hole 12 and toward the inside of the valve housing 10, the annular protrusion 121 extends toward the inside of the valve housing 10, and the connecting shaft 21 extends through the annular protrusion 121, through the hole 12, and to the outside of the valve housing 10 to be connected to the electric control device 60. Wherein, in the radial direction of the connecting shaft 21, there is a moving space between the annular protrusion 121 and the connecting shaft 21.

Further, the sealing member 30 is made of an elastic material, such as rubber or the like, which is not limited herein, and the sealing member 30 is configured in a ring shape, so that the sealing member 30 is externally sleeved at a region of the connecting shaft 21 near the through hole 12, that is, an inner circumferential wall of the sealing member 30 is in contact with the connecting shaft 21, and an outer circumferential wall of the sealing member 30 is in contact with the valve housing 10, so that the sealing member 30 performs a sealing function between the connecting shaft 21 and the valve housing 10.

For example, as shown in fig. 5, the sealing element 30 is located between the connecting shaft 21 and the annular protrusion 121, that is, the outer circumferential wall of the sealing element 30 is in contact with the inner circumferential wall of the annular protrusion 121, that is, the sealing element 30 is located in the movable space, that is, the sealing element 30 is located between the connecting shaft 21 and the annular protrusion 121, so as to facilitate the limiting and fixing of the sealing element 30, to enhance the structural stability of the sealing element 30, and to facilitate the sealing element 30 to play a sealing role between the connecting shaft 21 and the annular protrusion 121, so as to prevent the fluid in the valve housing 10 from overflowing along the gap between the hole 12 and the connecting shaft 21 when the connecting shaft 21 drives the body 22 to rotate in the valve housing 10, thereby enhancing the reliability of the dynamic sealing of the fluid valve 100.

As shown in fig. 6 and 7, the inner peripheral wall of the sealing element 30 is provided with a main sealing lip 31 and a first sealing lip 32, the main sealing lip 31 and the first sealing lip 32 both protrude in the radial direction of the sealing element 30, that is, in the axial direction of the connecting shaft 21, an annular sealing groove is defined between the main sealing lip 31 and the adjacent first sealing lip 32, in the axial direction of the connecting shaft 21, the main sealing lip 31 is located on one side of the first sealing lip 32 facing the body 22, the protruding length of the main sealing lip 31 is greater than that of the first sealing lip 32, and the main sealing lip 31 and the first sealing lip 32 are respectively in contact with the connecting shaft 21 and elastically deform.

In other words, the main sealing lip 31 and the first sealing lip 32 are spaced apart from each other in the axial direction of the sealing member 30, and the protruding length of the main sealing lip 31 is greater than that of the first sealing lip 32, and both the main sealing lip 31 and the first sealing lip 32 are elastically deformed to contact the connecting shaft 21 when the connecting shaft 21 is connected to the sealing member 30 in a sealing manner.

It should be noted that, because the main seal lip 31 directly contacts with the fluid in the valve housing 10, the main seal lip 31 is easily compressed excessively by the impact of the fluid, and the main seal lip 31 may be deformed to cause a seal failure. The main seal lip 31 still can also take place the elastic deformation inefficacy because long-term atress elastic deformation, and in short, main seal lip 31 can have the atress to warp and the risk of inefficacy, and the utility model discloses in, the protrusion length through setting up main seal lip 31 is greater than the protrusion length of first seal lip 32, so that the compressive deformation volume of main seal lip 31 department is greater than the compressive deformation volume of first seal lip 32, thereby warp and become invalid at main seal lip 31 atress, first seal lip 32 still can keep the elastic deformation volume, consequently warp and lead to its sealed back of inefficacy in main seal lip 31 department atress, the fluid can flow into the annular seal groove, the annular seal groove can play the effect of buffering to this part of fluid, and first seal lip 32 can block fluidic flow, and first seal lip 32 still plays sealed effect promptly.

It should be noted that when the main seal lip 31 does not fail, the compression deformation amount of the first seal lip 32 is small, and when the main seal lip 31 fails, the fluid directly impacts the first seal lip 32, so that the compression deformation amount of the first seal lip 32 is increased, and thus, the sum of the friction torque of the main seal lip 31 and the friction torque of the first seal lip 32 is not significantly increased.

In other words, after the main sealing lip 31 fails, only the initial contact pressure formed by the elastic deformation of the sealing member 30 itself remains, and the fluid pressure actually fails to the main sealing lip 31, because there is fluid pressure on both sides of the main sealing lip 31, and at this time, the fluid forces the first sealing lip 32 to deform through the failed main sealing lip 31, thereby increasing the compression amount of the first sealing lip 32, but since the deformation of the first sealing lip 32 is much smaller than that of the main sealing lip 31, the friction torque is not significantly increased, and may become smaller.

Therefore, the first sealing lip 32 can still keep in contact with the connecting shaft 21 after the main sealing lip 31 fails, in other words, when the main sealing lip 31 fails, the first sealing lip 32 forms a compensation seal, so that the sealing effect of the sealing element 30 is ensured, and the dynamic sealing reliability of the fluid valve 100 is improved.

It should be noted that the "protruding length" described herein includes a length protruding in a radial direction of the seal member 30, or a length protruding in a direction intersecting with the radial direction of the seal member 30, and is not limited herein.

In the prior art, since the sealing member 30 directly contacts the fluid in the valve housing 10, the sealing member 30 is deformed by the influence of pressure alternation and temperature change of the fluid, and the contact pressure between the main seal lip 31 and the connecting shaft 21 is reduced due to the deformation of the valve housing 10 and the abrasion of the main seal lip 31 caused by the friction of the connecting shaft 21 against the sealing member 30, so that the sealing of the sealing member 30 is failed, and the material elasticity of the main seal lip 31 is easily reduced by pressing the main seal lip 31 with the fluid pressure F (the fluid pressure is indicated by an arrow F in fig. 7) for a long time, so that the contact pressure is reduced, and further, the leakage failure is easily caused, and the reliability of the dynamic seal of the fluid valve 100 for a long period cannot be ensured.

And the utility model discloses in, through setting up main seal lip 31 and first seal lip 32, can receive above-mentioned influence factor and lead to main seal lip 31 to seal when becoming invalid at sealing member 30, first seal lip 32 still can with connecting axle 21 sealing contact to guarantee that sealing member 30 still can seal with connecting axle 21 and link to each other.

According to the utility model discloses fluid valve 100, its sealing member 30 overcoat in connecting axle 21 and with valve casing 10 contact, and the main seal lip 31 and the first seal lip 32 of sealing member 30 contact with connecting axle 21 respectively and take place to be out of shape, so as to play sealed effect between connecting axle 21 and valve casing 10, and in the axial direction of connecting axle 21, main seal lip 31 is located one side of the body 22 towards valve core 20 of first seal lip 32, and the protrusion length of main seal lip 31 is greater than the protrusion length of first seal lip 32, thereby when sealed inefficacy appears in main seal lip 31, can guarantee the sealing between connecting axle 21 and the valve casing 10 through first seal lip 32, with the leakproofness of reinforcing sealing member 30, avoid appearing leakage failure, and do benefit to the life who prolongs sealing member 30, improve the dynamic seal reliability of sealing member 30.

In some embodiments, the first sealing lip 32 is plural, and the plural first sealing lips 32 are provided at intervals in the axial direction of the connecting shaft 21.

For example, as shown in fig. 6 and 7, there are two first sealing lips 32, and the two first sealing lips 32 are sequentially distributed in the axial direction of the connecting shaft 21 toward the direction away from the body 22, so that when the main sealing lip 31 fails, compensation sealing can be sequentially achieved by the two first sealing lips 32, thereby facilitating multiple sealing effects through the plurality of first sealing lips 32.

Of course, the first sealing lip 32 may be provided in other numbers, and is not limited thereto.

Further, the plurality of first sealing lips 32 are different in projection length.

For example, the protruding lengths of the first sealing lips 32 are sequentially increased or sequentially decreased in the axial direction of the sealing member 30 away from the body 22, and of course, the protruding lengths of the first sealing lips 32 may be designed according to the actual sealing situation, and are not limited herein.

Preferably, the protruding length of the plurality of first seal lips 32 is gradually reduced in the axial direction away from the body 22.

In other words, in the axial direction away from the body 22, the compression deformation amount of the plurality of first seal lips 32 is gradually reduced, that is, it is ensured that even if one of the first seal lips 32 is forced to fail, the other first seal lips 32 still maintain the elastic deformation state to realize the sealing state, therefore, when the main seal lip 31 fails, the compensation sealing effect can be firstly achieved by the first seal lip 32 adjacent to the main seal lip 31, and when the first seal lip 32 adjacent to the main seal lip 31 fails, the compensation sealing effect can be better achieved by the next first seal lip 32, therefore, the compensation sealing effect can be achieved by the plurality of first seal lips 32 in sequence, and the sealing effect of the sealing element 30 is further enhanced.

In some embodiments, the axial width of the primary seal lip 31 is greater than the axial width of the first seal lip 32.

It will be appreciated that the primary seal lip 31 is in direct contact with the fluid in the valve housing 10, i.e. the primary seal lip 31 is subject to a greater pressure of the fluid. And the utility model discloses in, the axial width of main seal lip 31 is greater than the axial width of first seal lip 32, is convenient for increase main seal lip 31 and connecting axle 21's area of contact, strengthens the seal stability of main seal lip 31 and connecting axle 21, and then avoids main seal lip 31 to become invalid.

Meanwhile, when the connection shaft 21 is connected to the main sealing lip 31, the main sealing lip 31 can provide a proper radial force before and after the operation of the connection shaft 21, so as to reduce the wear between the main sealing lip 31 and the connection shaft 21, and at the same time, the main sealing lip 31 can prevent the fluid in the valve housing 10 from flowing out along the gap 40 between the sealing element 30 and the connection shaft 21, thereby enhancing the dynamic sealing performance of the fluid valve 100.

In some embodiments, the fluid valve 100 further includes a secondary sealing lip 33, the secondary sealing lip 33 contacting the connection shaft 21 and being deformed, and a protruding length of the secondary sealing lip 33 is greater than a protruding length of the first sealing lip 32.

Specifically, as shown in fig. 6 and 7, the secondary seal lip 33 is provided on the inner peripheral wall of the sealing member 30, and the secondary seal lip 33 is located on a side of the first seal lip 32 away from the body 22 and contacts with the connecting shaft 21, that is, the primary seal lip 31, the first seal lip 32, and the secondary seal lip 33 are all in sealing contact with the connecting shaft 21 in the axial direction of the connecting shaft 21, wherein the first seal lip 32 is located between the secondary seal lip 33 and the primary seal lip 31.

Therefore, when the main seal lip 31 and the first seal lip 32 both fail, the secondary seal lip 33 directly contacts with the fluid, in other words, when the main seal lip 31 and the first seal lip 32 both fail, the secondary seal lip 33 forms a compensation seal, that is, the main seal lip 31, the first seal lip 32 and the secondary seal lip 33 sequentially form multiple seals, thereby ensuring the sealing effect of the sealing element 30 and improving the dynamic sealing reliability of the fluid valve 100.

Preferably, the axial width of the secondary seal lip 33 is greater than the axial width of the first seal lip 32.

It will be appreciated that in the event of failure of both the primary seal lip 31 and the first seal lip 32, the secondary seal lip 33 is in direct contact with the fluid within the valve housing 10, i.e. the secondary seal lip 33 is subjected to the impact of the fluid. And the utility model discloses in, the axial width of inferior sealing lip 33 is greater than the axial width of first sealing lip 32, is convenient for increase inferior sealing lip 33 and connecting axle 21's area of contact, strengthens inferior sealing lip 33 and connecting axle 21's seal stability, and then avoids inferior sealing lip 33 to become invalid.

In some embodiments, as shown in fig. 7, both ends in the axial direction of the outer peripheral wall of the sealing member 30 are respectively in contact with the valve housing 10, and a gap 40 is provided between the remaining portion of the outer peripheral wall of the sealing member 30 and the valve housing 10.

It can be understood that both ends in the axial direction of the outer peripheral wall of the sealing member 30 are in sealing contact with the valve housing 10, respectively, so as to enhance the sealing property between the sealing member 30 and the valve housing 10, in other words, in the present invention, both ends in the axial direction of the outer peripheral wall of the sealing member 30 are in contact with the inner peripheral wall of the annular protrusion 121, respectively, and the static sealing of the sealing member 30 to the housing 121 can be formed.

As shown in fig. 7, a gap 40 is provided between the rest of the outer peripheral wall of the sealing member 30 and the valve housing 10, so that when fluid generates pressure on the sealing member 30, the sealing member 30 can play a certain buffering role by providing the gap 40, and the gap 40 is provided, which is beneficial to reducing the volume and weight of the sealing member 30, realizing the miniaturization and lightweight design of the sealing member 30, and simultaneously, being beneficial to saving materials and reducing the production cost.

In some embodiments, the groove formed between the primary seal lip 31 and the adjacent first seal lip 32 is used for storing lubricant, facilitating the assembly of the seal 30 onto the connecting shaft 21, and facilitating the lubrication between the primary seal lip 31, the first seal lip 32, and the secondary seal lip 33, the contact surfaces with the connecting shaft 21, during the product life.

In some embodiments, as shown in FIG. 7, at least one of the axially opposite end faces of the seal 30 is provided with an annular groove 50.

For example: any one of the two axial end faces of the sealing element 30 is provided with the annular groove 50, or the two axial end faces of the sealing element 30 are both provided with the annular groove 50, so that the reduction of the volume and the weight of the sealing element 30 is facilitated by the arrangement of the annular groove 50, the miniaturization and the light-weight design of the sealing element 30 are realized, meanwhile, the material saving is facilitated, and the production cost is reduced.

Preferably, as shown in fig. 7, in the axial direction of the seal 30, the sectional width of the annular groove 50 on the end surface close to the body 22 gradually increases toward the direction close to the body 22, and the sectional width of the annular groove 50 on the end surface away from the body 22 gradually increases toward the direction away from the body 22.

It should be noted that the end surface close to the body 22 is directly contacted with the fluid in the valve housing 10, that is, the end surface close to the body 22 is greatly influenced by the pressure of the fluid and the like.

Thus, the sectional width of the annular groove 50 on the end surface close to the body 22 is configured to be gradually increased toward the direction close to the body 22, so that when the fluid flows to the end surface, the fluid can be buffered by the annular groove 50, the impact force of the fluid on the sealing element 30 is reduced, and the structural stability of the sealing element 30 is enhanced.

Meanwhile, the sectional width of the annular groove 50 on the end surface far away from the body 22 is configured to be gradually increased toward the direction far away from the body 22, so that when the sealing element 30 is compressed and deformed by fluid pressure, a certain deformation space can be provided for the sealing element 30 through the annular groove 50, thereby reducing the impact force of the fluid on the sealing element 30 and further enhancing the structural stability of the sealing element 30.

In some embodiments, the annular groove 50 is diametrically opposed to the primary seal lip 31 or the secondary seal lip 33 in the radial direction of the seal 30.

For example, in the radial direction of the seal 30, the annular groove 50 on the end surface close to the body 22 is aligned with the primary seal lip 31, and the annular groove 50 on the end surface far from the body 22 is aligned with the secondary seal lip 33. Therefore, the main sealing lip 31 and the secondary sealing lip 33 are easy to deform, the sealing element 30 is convenient to assemble and disassemble, and the assembly and disassembly difficulty of the sealing element 30 is reduced.

In some embodiments, as shown in fig. 7, the cross-sectional shape of the seal member 30 is formed to be axisymmetrically arranged with respect to a first line L1 that is parallel to the radial direction of the seal member 30.

As shown in fig. 7, a dotted line L1 in the drawing is a first straight line, and the sealing element 30 is symmetrically disposed along the first straight line L1, so that the automated production of the sealing element 30 is facilitated, and the production difficulty is reduced.

In some embodiments, as shown in fig. 1, the fluid valve 100 further comprises: a packing 70 and a valve cover 80, the packing 70 being adapted to be installed in the valve housing 10 between the valve core 20 and the valve housing 10, the valve cover 80 being adapted to be installed at an end of the fluid valve 100 and connected to the valve housing 10 for preventing the valve core 20 from being separated from the valve housing 10.

In some embodiments, as shown in fig. 1 and 4, the body 22 is provided with at least one switching passage 221, the switching passage 221 is used for communicating two of the flow passage ports 11, and the body 22 is rotatably provided in the valve housing 10 to switch the switching passage to communicate with different flow passage ports 11.

When the switching channel 221 communicates with different flow passages 11, fluid can enter the fluid valve 100 or flow out of the fluid valve 100 through different flow passages, so that the fluid valve 100 has different operation modes.
