Technical Field

[0001] This utility model relates to the field of air inlet and outlet valve technology, and more specifically, to a rotary threaded air inlet and outlet valve. Background Technology

[0002] There are many types of inlet and outlet valves on the market, but most valves are single-function, typically only having a single function of inlet or outlet. In practical applications, when the operating mode of the system or equipment changes and it is necessary to switch the direction of gas inlet and outlet, it is necessary to replace the valve with one that has different functions, which is inconvenient. Therefore, we have made an improvement and proposed a rotary thread inlet and outlet valve. Utility Model Content

[0003] This utility model provides a rotary threaded inlet / outlet valve, including a valve seat assembly and a valve body assembly detachably connected to the valve seat assembly. The valve body assembly includes a valve core that can be installed with the valve seat assembly on both sides, and a hollowed-out baffle is provided inside the valve core. A through hole is provided in the middle of the hollowed-out baffle, and a first connecting post is inserted into the through hole. The first connecting post is connected to a first connecting cone and a sealing plate, and the first connecting cone and the sealing plate are respectively located on both sides of the hollowed-out baffle.

[0004] As a preferred technical solution of this application, when the valve core and valve seat assembly are installed in the correct direction, the sealing plate is located on the side of the hollowed-out baffle away from the valve seat assembly to form an exhaust valve, and the gas is discharged unidirectionally from the valve seat assembly to the valve body assembly.

[0005] As a preferred technical solution of this application, when the valve core and valve seat assembly are reversed, the sealing sheet is located between the hollowed-out baffle and the valve seat assembly to form an air intake valve, and gas is unidirectionally injected from the valve body assembly to the valve seat assembly.

[0006] As a preferred technical solution of this application, the valve seat assembly includes a valve seat body, a valve seat threaded connection ring is provided on the front side of the valve seat body, and an annular groove located inside the valve seat threaded connection ring is also provided on the front side of the valve seat body.

[0007] As a preferred technical solution of this application, the valve core includes an outer sleeve, an inner sleeve is provided inside the outer sleeve, one end of the inner sleeve is inserted into the inner wall of the annular groove, and a hollowed-out baffle is fixedly connected to the inner side of the inner sleeve. Several connecting plates are provided between the outer surface of the inner sleeve and the inner wall of the outer sleeve.

[0008] As a preferred technical solution of this application, a second threaded connecting ring is provided on one side of the outer sleeve. The second threaded connecting ring is used to connect with the valve seat threaded connecting ring when the valve body assembly is installed in the correct position.

[0009] As a preferred technical solution of this application, a first threaded connecting ring is provided on the other side of the outer sleeve. The first threaded connecting ring is used to connect with the valve seat threaded connecting ring when the valve body assembly is reversed.

A T-shaped cover is rotatably connected to the middle of the second connecting ring, and a threaded cover is connected to one end of the T-shaped cover.

[0012] As a preferred technical solution of this application, a sealing gasket is provided on the inner side of the threaded cover.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In the scheme of this application:

[0015] This application features a valve seat assembly and a valve body assembly, which are detachably connected. The valve core included in the valve body assembly can be installed either forward or backward. When the valve core is installed forward, the entire valve functions as an outlet valve, allowing gas to be discharged outward from the valve seat assembly towards the valve core. When the valve core is installed backward, the entire valve transforms into an inlet valve, allowing gas to be inflated from the valve core towards the valve seat assembly using an inflation device. This design allows users to flexibly switch between inlet and outlet functions without replacing the valve, simply by adjusting the valve core's installation direction. This improves ease of use and efficiency, meeting the needs for different gas inlet and outlet directions under various operating conditions. Attached Figure Description

The first connecting post 208 is connected to a first connecting cone 209 and a sealing plate 207. The first connecting cone 209 and the sealing plate 207 are located on both sides of the hollowed-out baffle 203, respectively. Figure 7 As shown, when the valve core and valve seat assembly 1 are installed in the correct orientation, the sealing plate 207 is located on the side of the hollowed-out baffle 203 away from the valve seat assembly 1, forming an exhaust valve, allowing gas to be discharged unidirectionally from the valve seat assembly 1 towards the valve body assembly 2. Figure 8 As shown, when the valve core and valve seat assembly 1 are installed in reverse, the sealing plate 207 is located between the hollowed-out baffle 203 and the valve seat assembly 1 to form an air inlet valve, and gas is unidirectionally filled from the valve body assembly 2 to the valve seat assembly 1. This design allows users to switch between air inlet and outlet functions flexibly without replacing the valve, simply by adjusting the valve core installation direction, which improves the convenience and efficiency of use and meets the needs of gas inlet and outlet directions under different working conditions.

[0033] Furthermore, the valve seat assembly 1 includes a valve seat body 101, on the front side of which a valve seat threaded connection ring 102 is provided, and an annular groove 103 located inside the valve seat threaded connection ring 102 is also provided on the front side of the valve seat body 101. The valve seat body 101 is used to connect with products that need to be charged or deflated, and to provide an installation base for the valve body assembly 2.

[0034] Furthermore, the valve core includes an outer sleeve 201, inside which is an inner sleeve 202. One end of the inner sleeve 202 is inserted into the inner wall of the annular groove 103. After the inner sleeve 202 is inserted into the annular groove 103, gas is transported through the annular groove 103 and the inner side of the inner sleeve 202. The hollowed-out baffle 203 is fixedly connected to the inner side of the inner sleeve 202. Several connecting plates 204 are provided between the outer surface of the inner sleeve 202 and the inner wall of the outer sleeve 201.

[0035] Furthermore, a second threaded connecting ring 206 is provided on one side of the outer sleeve 201. The second threaded connecting ring 206 is used to connect with the valve seat threaded connecting ring 102 when the valve body assembly 2 is installed in the correct position. At this time, the second threaded connecting ring 206 and the valve seat threaded connecting ring 102 are threadedly connected, and the threaded connection facilitates disassembly and assembly.

[0036] Furthermore, a first threaded connecting ring 205 is provided on the other side of the outer sleeve 201. The first threaded connecting ring 205 is used to connect with the valve seat threaded connecting ring 102 when the valve body assembly 2 is reversed. At this time, the first threaded connecting ring 205 and the valve seat threaded connecting ring 102 are threadedly connected, and the threaded connection facilitates disassembly and assembly.

[0037] Furthermore, a connecting component 3 is provided on the outer surface of the valve seat threaded connecting ring 102. The connecting component 3 includes a first connecting ring 301 rotatably sleeved on the outer surface of the valve seat threaded connecting ring 102. A second connecting post 302 is connected to the first connecting ring 301. The second connecting post 302 is connected to the outer sleeve 201. The specific connection between the second connecting post 302 and the outer sleeve 201 is as follows: a connecting hole 210 is opened on the outer sleeve 201. The end of the second connecting post 302 passes through the connecting hole 210 and extends between the outer sleeve 201 and the inner tube 202 and is fixedly connected to a second connecting cone 303. Through the mutual cooperation of the second connecting post 302 and the first connecting ring 301, the outer sleeve 201 and the valve seat threaded connecting ring 102 can be connected together, so that the valve body assembly 2 will not fall off after being separated from the valve seat assembly 1.

[0038] Furthermore, a connecting band 304 is connected to the first connecting ring 301, and a second connecting ring 305 is connected to the end of the connecting band 304 away from the first connecting ring 301. A T-shaped cover 4 is rotatably connected to the middle of the second connecting ring 305, and a threaded cover 401 is connected to one end of the T-shaped cover 4. When air intake and exhaust are not required, a seal can be achieved by connecting the threaded cover 401 with the first threaded connecting ring 205 or the second threaded connecting ring 206.

[0039] Furthermore, a sealing gasket 402 is provided on the inner side of the threaded cover 401. The sealing gasket 402 can improve the sealing performance when the threaded cover 401 is connected to the first threaded connecting ring 205 or the second threaded connecting ring 206.

[0040] The sealing sheet 207, the first connecting cone 209, the second connecting post 302, the second connecting cone 303, and the connecting strip 304 are all made of flexible rubber material, that is, the connecting strip 304 and the second connecting post 302 can be bent;

[0041] The sealing sheet 207 is made of flexible rubber material and utilizes its elastic deformation characteristics to separate from the hollowed-out baffle 203 under gas pressure to guide airflow; the first connecting cone 209 and the second connecting cone 303 are made of flexible rubber material, and the second connecting cone 303 can pass through the connecting hole 210 through the cone surface to form a limit, while the first connecting cone 209 passes through the through hole 211 to form a limit.

[0042] The rotary threaded air inlet / outlet valve provided by this utility model is used as follows:

[0043] The valve seat body 101 is connected to the product that needs to be charged or discharged. When used as an exhaust valve, i.e., the valve core is installed in the correct position, the second threaded connecting ring 206 is connected to the valve seat threaded connecting ring 102, and the sealing plate 207 is located on the side of the hollowed-out baffle 203 away from the valve seat assembly 1. The threaded cover 401 is threadedly connected to the first threaded connecting ring 205. When it is necessary to discharge the gas in the product, the threaded cover 401 is turned to separate the threaded cover 401 from the first threaded connecting ring 205. At this time, the outer side of the sealing plate 207 is separated from the hollowed-out baffle 203 under the action of air pressure, so that the gas can be discharged outward through the hollowed-out baffle 203. The exhaust can be stopped by connecting the threaded cover 401 to the first threaded connecting ring 205.

[0044] When used as an air intake valve, i.e., the valve core is installed in reverse, the first threaded connecting ring 205 is connected to the valve seat threaded connecting ring 102, and the sealing plate 207 is located between the hollowed-out baffle 203 and the valve seat assembly 1. The threaded cap 401 is threadedly connected to the second threaded connecting ring 206. When the product needs to be inflated, the threaded cap 401 is turned to separate the threaded cap 401 from the second threaded connecting ring 206. The inflator is used to inflate the inner tube 202. At this time, the outer side of the sealing plate 207 separates from the hollowed-out baffle 203 under the action of air pressure, so that the gas can enter the valve seat body 101 through the inner tube 202, thereby inflating the product. After inflation is completed, the threaded cap 401 and the second threaded connecting ring 206 are connected together.
