In addition, since the orientation of the reserved interface is fixed, the installation position of external devices is limited in a limited space, which leads to technical problems such as inconvenient installation. Moreover, heat will be absorbed during the rapid discharge of high-pressure gas, which makes it difficult for the external gas supply temperature to meet the use conditions. The inflation process will increase the temperature of the gas storage equipment, which will affect the stability of the physical and chemical properties of the gas. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] like Figure 1 As shown, the valve device provided by the embodiment of the present invention includes: a valve seat 001 and a valve body 002; the valve body 002 is inserted into the valve seat 001 and can rotate around the axis of the valve seat 001; the valve seat 001 is provided with a first limiting portion 101, and the valve body 002 is provided with a second limiting portion 201, and the first limiting portion 101 cooperates with the second limiting portion 201 to limit the valve body 002 axially relative to the valve seat 001.

[0031] Specifically, one of the first limiting portion 101 and the second limiting portion 201 is configured as a protrusion, and the other is configured as a groove for accommodating the protrusion. The first limiting portion 101 is matched with the second limiting portion 201, so that the valve body 002 can be axially limited relative to the valve seat 001, thereby preventing the valve body 002 from being separated from the valve seat 001. In addition, the valve body 002 can rotate around the axis of the valve seat 001 relative to the valve seat 001, and the direction of the valve body 002 can be adjusted, which is convenient for installing pipelines or other detection devices along the radial direction of the valve body 002. The valve body 002 can achieve 360° rotation relative to the valve seat 001, and the position and direction of the pipeline or other detection devices can be adjusted within a limited space, which is convenient for installation and adjustment of the device layout position.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, in an embodiment of the present invention, the valve seat 001 includes: a first seat body 110 and a second seat body 120, the first seat body 110 and the second seat body 120 are coaxial and connected, and the valve body 002 is inserted in the first seat body 110 and the second seat body 120 along the axis of the first seat body 110; the first limiting portion 101 includes an annular groove between the first seat body 110 and the second seat body 120; the second limiting portion 201 includes a protrusion inserted in the annular groove and rotating around the axis of the annular groove.

[0033] The first seat body 110 has a first flange, and the second seat body 120 has a second flange. The first flange is opposite to the second flange and connected by bolts, so that an annular groove is formed between the first seat body 110 and the second seat body 120. In addition, the end faces of the first seat body 110 and the second seat body 120 opposite to each other can be recessed, so as to form an annular groove by splicing. The first seat body 110 is sleeved on the valve body 002 from one end of the valve body 002, and the second seat body 120 is sleeved on the valve body 002 from the other end of the valve body 002. Then, the first seat body 110 and the second seat body 120 are connected, so that the valve body 002 can be axially positioned relative to the valve seat 001, and the valve body 002 can be rotated 360 degrees relative to the valve seat 001.

[0034] like Figure 1 As shown, a first sealing ring 003 is installed between the first seat body 110 and the valve body 002 , and the first sealing ring 003 surrounds the valve body 002 .

[0035] Specifically, the inner wall of the first seat body 110 or the outer wall of the valve body 002 is provided with a first sealing ring groove, and the first sealing ring 003 is installed in the first sealing ring groove. A plurality of first sealing rings 003 can be arranged at intervals along the axial direction of the first seat body 110, and the first seat body 110 is connected to the gas cylinder or the pipe of the inflatable equipment by means of a flange or a threaded fit. The first sealing ring 003 can prevent the gas from entering the gap between the first seat body 110 and the valve body 002, and the gas can only be inhaled and exhausted through the flow channel 202 of the valve body 002.

[0036] like Figure 1 As shown, a temperature control device 004 is installed in the valve body 002 , and the temperature control device 004 is used to adjust the temperature of the fluid flowing through the valve body 002 .

[0037] Among them, the valve body 002 is provided with an annular chamber surrounding the flow channel 202, and a temperature control device 004 is provided in the annular chamber. The temperature control device 004 includes a heating device, a cooling device or a temperature control plate. The inner side of the temperature control device 004 exchanges heat with the valve body 002, so as to adjust the temperature of the fluid in the flow channel 202. The outer side of the temperature control device 004 is covered with an insulation layer, so as to prevent heat and cold from being dissipated to the outside of the valve body 002 and the valve seat 001, thereby avoiding energy waste of cooling and heating.

[0038] like Figure 1 and Figure 2 As shown, the valve body 002 is provided with a side opening connected to the annular chamber, and the side opening is connected to the insulating end head 401. The side opening is blocked by the insulating end head 401 to prevent the cooling or heating energy of the temperature control device 004 from overflowing. The circuit of the temperature control device 004 passes through the insulating end head 401 and is connected to the controller 010.

[0039] like Figure 1 , Figure 2 and Figure 3 As shown, the valve body 002 is movably connected with a valve core 005, and the valve core 005 is used to adjust the opening and closing of the flow channel 202 of the valve body 002. The valve core 005 can slide along the radial direction of the valve body 002 or rotate around the axis extending radially thereof, and the flow channel 202 can be blocked by the valve core 005; and the opening penetrating the valve core 005 can be made to face the flow channel 202, so that the flow channel 202 can flow gas or liquid.

[0040] like Figure 1 As shown, a second sealing ring 006 is installed between the valve core member 005 and the valve body 002. The outer wall of the valve core member 005 or the surface of the valve body 002 facing the valve core member 005 is provided with a second sealing ring groove, and the second sealing ring 006 is installed in the second sealing ring groove. The second sealing ring 006 is pressed tightly between the valve core member 005 and the valve body 002, which can improve the sealing performance of the contact between the valve core member 005 and the valve body 002, and prevent the fluid from leaking through the gap between the valve core member 005 and the valve body 002.

[0041] like Figure 1 and Figure 2 As shown, the valve body 002 is installed with a pressure detection device 007, and the detection end of the pressure detection device 007 extends into the flow channel 202 of the valve body 002. The pressure detection device 007 is connected to the axial end of the valve body 002, and the valve core 005 is located between the pressure detection device 007 and the first seat body 110. When the valve core 005 is closed, the pressure detection device 007 can be isolated from the gas cylinder; when the valve core 005 is opened, the pressure detection device 007 can detect the gas pressure of the gas cylinder.

[0042] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the valve body 002 is provided with a plurality of joint parts 203, which are arranged at intervals around the axis of the valve seat 001, and the plurality of joint parts 203 are respectively connected to the flow channel 202 fluid of the valve body 002. External pipelines or detection devices can be connected respectively through the plurality of joint parts 203, thereby improving the equipment compatibility of the valve device.

[0043] like Figure 1 , Figure 2 and Figure 3 As shown, one of the joint parts 203 can be installed with a pressure-limiting blasting component 008, which is equipped with a bursting disc or an explosion-proof valve. When the pressure in the flow channel 202 is too high, the pressure-limiting blasting component 008 ruptures and opens, thereby releasing the fluid to avoid an explosion accident caused by excessive falling pressure.

[0044] Furthermore, the joint part 203 is equipped with a temperature detection device 009, which can be a platinum resistance temperature sensor, and is provided with a data interface for connecting to the controller 010. The controller 010 controls the temperature control device 004 to cool or heat according to the temperature signal of the temperature detection device 009, thereby making the temperature of the fluid flowing through the valve body 002 within a preset temperature range.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
