[0009] The gland seal is arranged at the top opening of the time integration block, with its inner side abutting against the top of the valve core. Rotating the gland drives the valve core to move along the length direction of the time integration block, and adjusts the preset distance between the side wall at the bottom of the valve core and the regulating air outlet.
[0010] In a possible implementation manner, the bottom of the valve core is embedded inside the regulating air outlet, and cooperates with the regulating air outlet to form a regulating air outlet with an annular structure.

The structure of the valve core and the sealing sleeve forms a ring-shaped adjustable air outlet, which optimizes the control effect of gas flow. Specifically, the device offers several key features: precise control (gas flow and pressure can be precisely controlled through valve core adjustment, ensuring system stability and accuracy); efficient regulation (the time integral block design allows for effective gas integration and regulation, enabling rapid response and adjustment); reliable sealing performance (the design and layout of the sealing sleeve ensure a good seal during gas flow, preventing gas leakage and improving system reliability); flexible adjustment (the valve core is adjusted by rotating the gland, providing flexibility and convenience for operation); and simple and reliable structure (the entire device has a relatively simple structure, is easy to manufacture and maintain, and possesses high reliability and durability). In conclusion, this device has broad application prospects in the field of gas control, providing stable, efficient, and reliable control for various pneumatic systems, bringing significant practical value and economic benefits to users.

[0042] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.
[0043] See Figure 1 and Figure 2The pneumatic control air-capacitor device of this application embodiment includes: an air-capacitor air passage block 10, a time integration block 110, a sealing sleeve 120, a valve core 130, and a pressure cap 140. The air-capacitor air passage block 10 has an air-capacitor cavity, and an air passage inlet and an air passage outlet. The air passage outlet is connected to the bellows of the pneumatic PI calculation device through the air-capacitor cavity, and the air passage inlet is connected to the cavity of the pneumatic PI calculation device through the air-capacitor cavity. The time integration block 110 is a barrel-shaped structure open at both ends, with an air inlet at the bottom, which connects to the interior of the side wall of the time integration block 110. The time integration block 110 is disposed on the air-capacitor air passage block 10, with an air outlet 111 corresponding to the air passage outlet. The bottom opening of the time integration block 110 corresponds to the air passage inlet. The sealing sleeve 120 is embedded inside the time integration block 110, and the sealing sleeve 120 is a barrel-shaped structure open at both ends, with the side wall... It is connected to the air inlet and has an adjustable air outlet 121 at the bottom. The adjustable air outlet 121 corresponds to the air outlet 111, and the cross-sectional diameter of the adjustable air outlet 121 gradually decreases in the direction away from the sealing sleeve 120. The valve core 130 is located inside the sealing sleeve 120, and the bottom of the valve core 130 has a frustum-shaped structure. The side wall of the valve core 130 is spaced at a preset distance from the adjustable air outlet 121 of the sealing sleeve 120. The pressure cap 140 is sealed at the top opening of the time integration block 110, and its inner side abuts against the top of the valve core 130. Rotating the pressure cap 140 causes the valve core 130 to move along the length direction of the time integration block 110, thereby adjusting the preset distance between the side wall of the bottom of the valve core 130 and the adjustable air outlet 121.
[0044] In this embodiment, the flow rate of compressed air passing through the time integrator block 110 can be artificially controlled to achieve a pressure lower than that of the compressed air entering the precision gas container, but the pressure in the gas container always changes towards the pressure of the compressed air entering. The gas container block 10 has a gas container cavity and is connected to the pneumatic PI calculation device through the gas inlet and gas outlet. The time integrator block 110 is a barrel-shaped structure with an air inlet and an air outlet 111 for regulating gas flow. The sealing sleeve 120 is nested inside the time integrator block 110 and has an adjustable air outlet 121. It cooperates with the valve core 130 to form a flow control channel. The valve core 130 is located inside the sealing sleeve 120, and its position is adjusted by rotating the pressure cap 140, thereby adjusting the size of the air outlet 121 to achieve flow control. The structure of the valve core 130 and the sealing sleeve 120 forms a circular adjustable air outlet 121, which optimizes the control effect of gas flow. Specifically, the device offers several key features: precise control: Gas flow and pressure can be precisely controlled through the adjustment of valve core 130, ensuring system stability and accuracy; efficient regulation: the design of the time integrator block 110 allows for effective gas integration and regulation, enabling rapid response and adjustment; reliable sealing performance: the design and layout of the sealing sleeve 120 ensures a good seal during gas flow, preventing gas leakage and improving system reliability; flexible adjustment: valve core 130 is adjusted by rotating the gland 140, providing flexibility and convenience in the adjustment process, making operation easier; and simple and reliable structure: the entire device has a relatively simple structure, is easy to manufacture and maintain, and possesses high reliability and durability. In conclusion, this device has broad application prospects in the field of gas control, providing stable, efficient, and reliable control effects for various pneumatic systems, bringing significant practical value and economic benefits to users.
[0045] In one specific embodiment, see Figure 12 The bottom of the valve core 130 is embedded inside the regulating air outlet 121, forming a circular regulating air outlet 121 with the regulating air outlet 121. The position of the valve core 130 is adjusted by rotating the pressure cap 140, thereby controlling the relative size of the regulating air outlet 121, that is, the preset distance between the bottom of the valve core 130 and the inner side of the regulating air outlet 121, to achieve flow control. The structure of the valve core 130 and the sealing sleeve 120 forms a circular regulating air outlet 121, which optimizes the control effect of gas flow.
[0046] In this embodiment, see Figure 5 The valve core 130 has a needle-like structure with a frustum-shaped bottom. The cross-sectional diameter gradually decreases along the direction away from the top of the valve core 130. The bottom of the valve core 130, in conjunction with the regulating air outlet 121, can control the air flow rate, and the cross-sectional diameter of the bottom of the valve core 130 is always smaller than the cross-sectional diameter of the regulating air outlet 121.
[0047] In this embodiment, referring to Figure 12 and Figure 4 , the air outlet 121 is adjusted to be in a funnel-shaped structure, and the valve core 130 is inserted from the side with a larger opening of the air outlet 121. The bottom of the valve core 130 with a needle-like structure is inserted into the air outlet 121 and moves along the opening direction of the air outlet 121, so that the distance between the bottom of the valve core 130 and the inner side wall of the air outlet 121 increases or decreases, thereby increasing or decreasing the cross-sectional area of the annular air outlet 121.
[0048] In a specific embodiment, referring to Figure 12 and Figure 6 , the gland 140 has a "convex" shape structure, and a valve core adjustment groove 141 is opened at the bottom. The top of the valve core 130 is embedded and fixedly connected inside the valve core adjustment groove 141, which is convenient for controlling the position of the valve core 130, so as to adjust the gas flow rate at the position of the adjusted air outlet.
[0049] In this embodiment, the gland 140 is embedded in the top opening of the time integration block 110, and the gland 140 is threadedly connected to the time integration block 110 and can rotate relative to the top opening of the time integration block 110 and move towards the inside or outside of the time integration block 110, thereby driving the valve core 130 to move along the length direction of the time integration block 110.
[0050] In this embodiment, the top of the valve core 130 is embedded and fixedly connected inside the valve core adjustment groove 141 on the inner side of the gland 140, so that the valve core 130 can move with the movement of the gland 140.
[0051] In a specific embodiment, referring to Figure 12 and Figure 6 , a rotating part extends from the top of the gland 140 in a direction away from the gland 140, and a rotating groove is opened at the top of the rotating part. The rotating groove is in a long strip shape. Specifically, the extended rotating part is located outside the time integration block 110, which is convenient for using a flat screwdriver to rotate the gland 140.
[0052] Among them, referring to Figure 12 and Figure 5 , the bottom of the valve core 130 is an adjusting part, and the whole of the adjusting part has a frustum-shaped structure. The length of the adjusting part is greater than the movable length of the gland 140 relative to the time integration block 110, and the used part of the adjusting part is located inside the air outlet 121, and can always control the opening size of the air outlet 121.
[0053] In a specific embodiment, referring to Figure 2The gas container gas passage block 10 has a time integration block 110 mounting groove. The gas passage inlet and gas passage outlet are opened on the bottom wall of the gas passage inlet and gas passage outlet, and the time integration block 110 mounting groove matches the time integration block 110. The time integration block 110 is embedded in the time integration block 110 mounting groove, and the gas passage outlet corresponds to the gas outlet 111. The gas passage inlet corresponds to the bottom opening of the time integration block 110, which is used to fix the time integration block 110 on the gas container gas passage block 10.
[0054] In this embodiment, an air outlet is provided in the middle of the mounting groove of the time integration block 110, an air inlet is provided at the upper left corner of the air outlet, and fixing holes are provided at the upper right and lower left corners of the air outlet for fixing the time integration block 110 on the gas container air passage block 10.
[0055] In this embodiment, the time integrating block 110 has a cuboid structure with an internal columnar cavity structure. The mounting groove of the time integrating block 110 is a square groove that matches the shape and structure of the time integrating block 110. Specifically, when the time integrating block 110 is installed inside the mounting groove, the air outlet corresponds to the air outlet 111, the air inlet corresponds to the bottom opening of the time integrating block 110, and the mounting holes correspond to the mounting holes on the time integrating block 110 for bolt installation and connection.
[0056] In this embodiment, the corners of the square-shaped time integration block 110 are rounded.
[0057] In one specific embodiment, see Figure 12 and Figure 4 A first fixing part 122 extends circumferentially from the outside of the sealing sleeve 120. The cross-section of the first fixing part 122 is annular, and the diameter of the annular first fixing top is equal to the diameter of the inner cross-section of the time integrating block 110. The sealing sleeve 120 is fixedly embedded inside the time integrating block 110. There are two or more first fixing tops, spaced apart along the length of the sealing sleeve 120. By embedding the first fixing part 122 of the sealing sleeve 120 into the interior of the time integrating block 110, the annular design of the first fixing part 122 ensures that the sealing sleeve 120 is firmly embedded inside the time integrating block 110, which helps to improve the structural stability of the overall device. Furthermore, having two or more first fixing parts 122 may provide a more robust fixing effect and increase the durability of the device. The diameter of the annular first fixing top is equal to the diameter of the inner cross-section of the time integrating block 110, ensuring a perfect match between the sealing sleeve 120 and the time integrating block 110, thereby improving installation accuracy.
[0058] In this embodiment, the air inlet can be connected to the interior of the sealing sleeve 120 from the side wall or top opening of the time integration block 110.
[0059] In this embodiment, the first fixing part 122 of the annular structure can effectively achieve sealing and prevent gas leakage.
[0060] In one specific embodiment, see Figure 12 and Figure 5 A second fixing part 131 extends from the outside of the valve core 130 along the circumferential direction of the valve core 130. The cross-section of the top of the second fixing part 131 is annular. The cross-sectional diameter of the second fixing part 131 is smaller than the internal cross-sectional diameter of the sealing sleeve 120, so as to be stably installed inside the sealing sleeve 120.
[0061] In this embodiment, the second fixing part 131 is an annular structure, and its outer diameter is slightly smaller than the inner diameter of the sealing sleeve 120, so that the valve core 130 can maintain the same direction as the sealing sleeve 120.
[0062] In this embodiment, the second fixing part 131 can also play a sealing role, and the annular structure of the first fixing part 122 can effectively achieve sealing and prevent gas leakage.
[0063] In one specific embodiment, see Figure 12 The regulating outlet 121 is located on the bottom side wall of the sealing sleeve 120, adjacent to the regulating inlet 123. The regulating outlet 121 is connected to the inlet of the time integral block 110, which can deliver gas to the interior of the sealing sleeve 120.
[0064] In this embodiment, the sealing sleeve 120 is installed inside the time integration block 110 through the first fixing part 122, so that the sealing sleeve 120 and the time integration block 110 are relatively fixed. At this time, the adjustment air inlet 123 opened on the sealing sleeve 120 corresponds to and is connected to the air inlet provided on the time integration block 110.
[0065] In this embodiment, the regulating air inlet 123 is located at the bottom of the side wall of the sealing sleeve 120, close to the regulating air outlet 121, so that the incoming gas can be transported from the regulating air outlet 121 to the interior of the gas container block 10.
[0066] In one specific embodiment, the air outlet, the regulating air outlet 121, the bottom opening of the sealing sleeve 120 and the valve core 130 are coaxially arranged.
[0067] In one specific embodiment, see Figure 1 and Figure 2 The manual / automatic reversing module is installed on the gas-capacity gas path block 10 to control whether the gas path passes through the integral time module.
[0068] In this embodiment, the manual-automatic commutation module includes: a commutation air path block 210, a commutation shunt piece 220, a commutation knob 230, a commutation knob 230 pressing piece 240, and a hand-operated knob 250. By manually rotating the hand-operated knob 250, the angle of the commutation knob 230 changes, thereby changing the air path, enabling the compressed air in two different air paths to selectively switch and enter the air capacitance cavity. Moreover, through this module, it is also possible to select whether the compressed air passes through the integration time module.
[0069] In this embodiment, referring to Figure 2 , the air capacitance air path block 10 is provided with a commutation air path block 210 installation groove, and the commutation air path block 210 installation groove has a "convex" structure for installing and placing the commutation air path block 210. Among them, an external air vent, an internal air vent, and a ventilation outlet are opened on the bottom wall of the commutation air path block 210 installation groove. The external air vent is used to connect to an external standard air source. The internal air vent is connected to the air outlet 111 of the integration time module through the internal air capacitance cavity of the air capacitance air path block 10. The ventilation outlet is connected to the bellows through the internal air capacitance cavity of the air capacitance air path block 10.
[0070] In this embodiment, referring to Figure 7 , the overall shape of the commutation air path block 210 is "convex", which matches the commutation air path block 210 installation groove and can be placed inside the commutation air path block 210 installation groove. The commutation air path block 210 is used to arrange the commutation shunt piece 220, the commutation knob 230, the commutation knob 230 pressing piece 240, and the hand-operated knob on the air capacitance air path block 10. Specifically, the commutation air path block 210 is recessed with a commutation installation groove, and through holes communicating with the external air vent, the internal air vent, and the ventilation outlet are opened at the bottom, facilitating gas input for commutation.
[0071] In this embodiment, referring to Figure 8 , the commutation shunt piece 220 is a circular plate structure, and a commutation air inlet 223, a first commutation air inlet 222, a second commutation air inlet 224, and a commutation air outlet 221 are opened along the circumferential direction of the plate surface. Among them, the commutation air inlet 223, the first commutation air inlet 222, and the second commutation air inlet 224 are adjacent and are connected in sequence in an arc shape. By rotating the commutation knob 230, the gas path can be changed, enabling the first commutation air inlet 222 to communicate with the commutation air inlet 223, or the second commutation air inlet 224 to communicate with the annular air inlet, and the commutation air inlet 223 is connected to the commutation air outlet 221 to achieve air exchange and introduce the gas into the interior of the air capacitance path.
[0072] Specifically, the reversing divider 220 is provided with a first reversing vent slot 227, a second reversing vent slot 226, a third reversing vent slot 228, and a fourth reversing vent slot 225. The first reversing vent slot 227 corresponds to the reversing air inlet 223, the second reversing vent slot 226 corresponds to the first reversing air inlet 222, the third reversing vent slot 228 corresponds to the second reversing air inlet 224, and the fourth reversing vent slot 225 corresponds to the reversing air outlet 221. Specifically, the cross-sections of the first reversing vent slot 227, the second reversing vent slot 226, the third reversing vent slot 228, and the fourth reversing vent slot 225 are all arc-shaped, and the reversing air inlet 223 of the first reversing vent slot 227 extends towards the first reversing air inlet 222 and the second reversing air inlet 224, respectively. The second reversing vent 226 extends toward the reversing inlet 223, the third reversing vent 228 extends toward the reversing inlet 223, and the direction of extension of the reversing outlet 221 is not limited. However, the first reversing vent 227, the second reversing vent 226, the third reversing vent 228 and the fourth reversing vent 225 can extend and connect to form a ring structure.
[0073] In this embodiment, see Figure 9 The reversing knob 230 has a boss structure, with the side with a larger cross-section being the reversing side and the side with a smaller cross-section being the rotating side. The reversing side of the reversing knob 230 has a reversing air inlet groove 232 and a reversing air outlet groove 231. The cross-section of the reversing air inlet groove 232 is arc-shaped, and its arc length is equal to the arc length between the first reversing air inlet 222 and the reversing air inlet 223, i.e., equal to the arc length between the second reversing air inlet 224 and the reversing air inlet 223. By rotating the reversing knob 230, either the first reversing air inlet 222 or the second reversing air inlet 224 can be connected to the reversing air inlet 223, and only one of them can be used for ventilation. Furthermore, a rotating rod extends from the rotating side of the reversing knob 230 in a direction away from the reversing knob 230, facilitating manual rotation of the reversing knob 230.
[0074] In this embodiment, see Figure 10 The reversing knob 230 pressure plate 240 has a plate-like structure and a through hole through which the rotating rod can pass, clamping the reversing knob 230 between the reversing knob 230 pressure plate 240 and the reversing branch plate 220.
[0075] In this embodiment, see Figure 11 The hand lever knob is connected to the rotation rod of the reversing knob 230. By rotating the hand lever knob, the rotation of the reversing knob 230 can be controlled, switching the output to an automatic signal or a manual signal.
[0076] According to the above embodiments, the overall usage process is as follows: Initial setup: First, the sealing sleeve 120 is installed inside the time integration block 110 via the first fixing part 122, fixing its position relatively. At this time, the regulating air inlet 123 on the sealing sleeve 120 is connected to the air inlet on the time integration block 110. Gas delivery: By adjusting the opening of the air outlet 121 at the bottom side wall of the sealing sleeve 120, which is close to the regulating air inlet 123, gas can enter the regulating air outlet 121 and be delivered to the interior of the sealing sleeve 120 through communication with the air inlet of the time integration block 110. Manual / automatic reversing module usage: The manual / automatic reversing module is installed on the gas-container gas path block 10 to control whether the gas path passes through the integration time module. The manual / automatic reversing module includes a reversing gas path block 210, a reversing branch plate 220, a reversing knob 230, a reversing knob 230 pressure plate 240, and a manual knob. By manually rotating the lever knob, the angle of the reversing knob 230 can be changed, thereby altering the air path and selecting whether compressed air passes through the integral time module. The reversing air path block 210 has a recessed, "convex" shaped structure for mounting. Within the "convex" shaped structure of the reversing air path block 210, the reversing branch plate 220, the reversing knob 230, the reversing knob 230 pressure plate 240, and the lever knob are placed on the air-capacity air path block 10. Air path switching: By rotating the reversing knob 230, the air path can be changed, connecting the first reversing inlet 222 with the reversing inlet 223, or connecting the second reversing inlet 224 with the annular inlet, thereby allowing gas to enter the interior of the air-capacity air path block 10. Operation of the reversing knob 230: The rotation of the reversing knob 230 is controlled by turning the hand lever knob, thereby controlling the reversal of the air path and achieving the purpose of switching the air path. The manual and automatic reversing modules and the reversing air path block 210 can be operated as needed to realize the air path switching, and at the same time control the gas delivery to the inside of the sealing sleeve 120 to switch the output to an automatic signal or a manual signal.
