Referring to fig. 1, the present embodiment provides a valve structure 10, and the valve structure 10 includes a valve seat 11, a valve core 12, a sealing member 13, and a resilient retaining assembly 14. The valve seat 11 is formed with a passage 111. The spool 12 is inserted in the passage 111. The sealing element 13 is sleeved on the valve core 12. The seal 13 seals a gap between the side wall of the passage 111 and the spool 12. The elastic catching assembly 14 is provided on the valve seat 11, and the elastic catching assembly 14 elastically catches the spool 12 to restrict the spool 12 from moving in a depth direction of the passage 111.

In particular, the valve structure 10 is suitable for use in a fluid system, and the means for controlling the direction, pressure, and flow rate of a fluid is a means for allowing or stopping the flow of a medium in the valve structure 10 and a pipe line associated with the valve structure 10 and controlling the flow rate thereof. The medium may be a liquid, a gas, a powder, or the like having fluidity.

The valve seat 11 is a detachable component in the valve structure 10, the diameter of the valve seat 11 is generally the maximum flow diameter of fluid in the valve structure 10, and the valve seat 11 may be made of plastic or metal. A through-going passage 111 is left inside the valve seat 11, and the passage 111 is mainly used for installing other components in the valve structure 10.

The valve structure 10 can perform basic functions such as control of the direction of the medium, pressure control, or flow control by means of the valve element 12. The valve core 12 is made of mainly bronze or stainless steel, and also made of plastic, nylon, ceramic, glass, etc., the shape of the valve core 12 can be generally divided into spherical, conical, disk-shaped, cylindrical, etc., and the valve core 12 is inserted into the channel 111 in the valve seat 11 to control the flow direction and flow rate of the medium in the valve structure 10.

The sealing member 13 is a member for preventing fluid from leaking from between adjacent contact surfaces in the valve structure 10 and preventing foreign substances such as dust and moisture from entering the interior of the valve structure 10. The sealing material 13 is usually made of rubber, and may be made of nylon, polyurethane, engineering plastic, or the like. In order to avoid premature aging of the sealing member 13 and thus the sealing effect, the sealing member 13 is generally stored at a temperature below 30 ℃ and under conditions avoiding strong light irradiation.

In the embodiment of the present application, the sealing member 13 is sleeved on the groove 121 of the valve element 12, and the sealing member 13 is tightly attached to the side wall of the groove 121 of the valve element 12 and the side wall of the channel 111 in the valve seat 11, so as to seal the gap between the side wall of the channel 111 and the valve element 12, thereby preventing the leakage of fluid and the intrusion of impurities in the valve structure 10.

The elastic clamping assembly 14 mainly has the functions of fixing and limiting, the elastic clamping assembly 14 is distributed on the valve seat 11, and the elastic clamping assembly 14 elastically clamps the valve core 12 to fix the position of the valve core 12, so as to limit the movement of the valve core 12 in the depth direction of the channel 111.

In this way, in the valve structure 10 according to the embodiment of the present application, the elastic retaining assembly 14 elastically retains the valve element 12 to limit the movement of the valve element 12 in the depth direction of the channel 111, so that the valve element 12 can be prevented from being connected with the valve seat 11 in a rotating manner, and thus the compression and abrasion of the sealing member 13 can be reduced, and the failure risk of the sealing member 13 can be reduced.

In some embodiments, the elastic retaining assembly 14 includes a spring 141 and a retaining member 142, the retaining member 142 is disposed between the spring 141 and the valve element 12, and the spring 141 provides an elastic force to the retaining member 142 to enable the retaining member 142 to retain the valve element 12.

Specifically, the elastic piece 141 can be generally divided into a straight spring and a bent spring according to the difference of the structure, the shape is rectangular, trapezoidal, triangular, and stepped, and the like, the elastic piece 141 can be made of 65Mn alloy steel, phosphor bronze, and tin bronze, and the elastic piece 141 is easy to bend only in one direction, i.e., the plane with the minimum stiffness, and has large tensile stiffness and bending stiffness in the other direction. Therefore, the elastic piece 141 is very suitable for being used as an elastic supporting element. The retaining member 142 is disposed between the elastic piece 141 and the valve core 12, and can fix the position of the valve core 12, so as to prevent the valve core 12 from sliding down along the depth direction of the channel 111.

Thus, the elastic sheet 141 is installed in the valve seat 11 and contacts with the retaining member 142 in a large area, and the retaining member 142 is installed between the elastic sheet 141 and the valve element 12, so that the elastic sheet 141 can provide elastic force to the retaining member 142 to support the retaining member 142 to retain and fix the valve element 12, and meanwhile, the elastic sheet 141 can also fix the retaining member 142 without falling off, thereby better retaining the valve element 12.

In some embodiments, the valve core 12 is formed with a catching groove 122, the catching groove 122 extends in a radial direction of the valve core 12, and the catching member 142 is partially caught in the catching groove 122.

The outer side of the valve core 12 is provided with a clamping groove 122, the clamping groove 122 extends along the diameter direction of the valve core 12, a part of the clamping member 142 is clamped in the clamping groove 122, and the other end of the clamping member 142 is contacted with the elastic sheet 141. When the valve structure 10 is installed, the valve element 12 is inserted into the valve seat 11 to the position shown in fig. 1, the retainer 142 is engaged with the valve element 12 in the position-restricting groove, and the valve element 12 is fixed. In this way, the retaining member 142 can abut against the valve core 12 through the catching groove 122 of the valve core 12, thereby preventing the valve core 12 from sliding down along the channel 111.

In some embodiments, the retaining member 142 is spherical, and the spring 141 is formed with an arc surface 144 that conforms to a surface of the retaining member 142.

Specifically, the retaining member 142 is spherical, and the surface of the elastic sheet 141 contacting the retaining member 142 is an arc surface 144. In this way, the spherical catching member 142 can reduce the resistance received by the catching member 142 when catching the valve element 12; the arc-shaped surface 144 of the elastic sheet 141 contacting the retaining member 142 can increase the connection area, and the elastic sheet 141 contacts the retaining member 142 more closely, so that the elastic sheet 141 can provide a larger elastic force for the retaining member 142.

In some embodiments, the elastic sheet 141 is accommodated in the valve seat 11, and the valve seat 11 is formed with an avoiding space 112 for avoiding deformation of the elastic sheet 141.

A certain avoiding space 112 is formed in the valve seat 11, and the elastic sheet 141 can be accommodated in the avoiding space 112, so that the installation and the disassembly of the elastic sheet 141 can be facilitated.

In some embodiments, the valve seat 11 is formed with a through hole 1121 extending from an outer surface of the valve seat 11 to the escape space 112, and the elastic piece 141 is exposed to the outside of the valve seat 11 through the through hole 1121.

The escape space 112 in the valve seat 11 is a through hole 1121 extending outward from the inside of the valve seat 11 to the outer surface of the valve seat 11, and the elastic piece 141 is disposed in the escape space 112 in the valve seat 11, and the elastic piece 141 can be exposed to the outside of the valve seat 11 through the through hole 1121. Further, when the elastic sheet 141 is lifted up manually, the retaining member 142 is in a natural state due to loss of contact with the elastic sheet 141, that is, the retaining member 142 does not fix the valve element 12, so that the valve element 12 can be detached quickly and conveniently; then the valve core 12 is inserted into the valve seat 11 to the position shown in fig. 1, the retaining member 142 is matched with the valve core 12 in a limiting groove, after the human elastic sheet 141 is put down, the elastic sheet 141 is in large-area contact with the retaining member 142, and the retaining member 142 is in a retaining state and can provide larger elastic force for the retaining member 142 to limit the valve core 12.

In some embodiments, the elastic retaining assembly 14 includes an elastic member 143 connected to one end of the elastic piece 141, and the elastic member 143 is configured to provide a restoring force to the elastic piece 141 after the elastic piece 141 is deformed.

The elastic member 143 is a member that deforms under an external force and returns to its original shape when the external force is removed. Generally, there are leaf springs, flat coil springs, rotary springs, pressure spring tubes, bellows, and the like. One end of the elastic piece 141 contacts with the holding member 142, and the other end of the elastic piece 141 is connected with the elastic member 143. Thus, the elastic element 143 can provide a restoring force to the elastic piece 141 after the elastic piece 141 is deformed.

In some embodiments, the number of the elastic sheets 141 and the retaining members 142 is multiple, the elastic sheets 141 and the retaining members 142 are arranged in a one-to-one correspondence, and the retaining members 142 are arranged at intervals along the circumferential direction of the valve element 12.

In the valve structure 10, the number of the elastic pieces 141 and the retaining pieces 142 is plural, including 2, 3, 4, 5, and 6, and the like, which is not limited herein. It should be noted that the elastic sheets 141 and the retaining members 142 are in one-to-one correspondence, that is, in the valve structure 10, the number of the elastic sheets 141 and the retaining members 142 is the same, and since the retaining members 142 are matched with the limiting grooves of the valve element 12, the number of the clamping grooves 122 of the valve element 12 is also the same as the number of the elastic sheets 141 and the retaining members 142. The retaining members 142 are disposed at equal intervals along the circumferential direction of the valve core 12, so that the valve structure 10 is more attractive, and the service life of each retaining member 142 is prolonged due to the same stress.

Referring to fig. 2, an embodiment of the present application provides a vehicle-mounted refrigeration system 100. The vehicle-mounted refrigeration system 100 includes a refrigerant pipeline 20 and the valve structure 10, and the valve structure 10 is disposed on the refrigerant pipeline 20.

The in-vehicle refrigeration system 100 is a device that cools air in a vehicle compartment. The refrigerant pipe 20 is a pipe of the connector valve structure 10 in the in-vehicle refrigeration system 100, and a copper pipe is generally used. The valve structure 10 is disposed on the refrigerant pipeline 20, and the refrigerant pipeline 20 is mainly responsible for conveying the medium. The main working principle is as follows: the medium is injected into the channel 111 from the inlet at the upper end of the channel 111 by compressing the spring and simultaneously flows out from the bottom of the channel 111, and when the pressure of the medium reducing medium is reduced, the valve plug is pressed against the outlet at the bottom of the channel 111. The bottom of the valve structure 10 is provided with a liquid outlet hole from which the medium flows into the refrigerant pipe.

Referring to fig. 3, the present embodiment further provides a vehicle 1000. The vehicle 1000 includes a vehicle body 200 and the above-described in-vehicle refrigeration system 100, and the in-vehicle refrigeration system 100 is provided on the vehicle body 200.
