[0014] Based on the above technical solutions, the technical effects achievable by this invention can be analyzed as follows: The equalizing pressure regulating binary mixer provided by this invention includes an equalizing pressure control valve and a proportional regulating valve. The equalizing pressure control valve includes a control valve body, a primary gas diaphragm, a secondary gas diaphragm, a proportional regulating rod, and a regulating filter element. The control valve body is provided with a primary gas chamber, a secondary gas chamber, a regulating pipe, and a mixing chamber. The primary gas diaphragm is installed in the primary gas chamber, dividing the primary gas chamber into a primary gas chamber and a third gas chamber.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0025] In existing technologies, gases are first mixed and then adjusted using detection instruments, which cannot achieve rapid mixing and use.

[0026] In view of this, see Figures 1 to 6 The equalizing pressure regulating binary mixer provided in this embodiment of the invention includes an equalizing pressure control valve and a proportional regulating valve. The equalizing pressure control valve includes a control valve body 201, a primary gas membrane 203, a secondary gas membrane 207, a proportional regulating rod 213, and a regulating filter element 215. The control valve body 201 is provided with a primary gas chamber, a secondary gas chamber, a regulating pipe, and a mixing chamber. The primary gas membrane 203 is installed in the primary gas chamber, dividing the primary gas chamber into a primary gas chamber and a third gas chamber. The secondary gas membrane 207 is installed in the secondary gas chamber, dividing the secondary gas chamber into a secondary gas chamber and a third gas chamber. The system has six chambers, with the main chamber and the sixth chamber in fluid communication, and the third chamber and the secondary chamber in fluid communication. The two ends of the regulating pipe are connected to the main chamber and the secondary chamber respectively, and the regulating filter element 215 is located inside the regulating pipe. The regulating pipe is connected to the mixing chamber through the regulating filter element 215. One end of the proportional regulating rod 213 extends into the interior of the regulating filter element 215 and separates the regulating filter element 215. The other end is connected to the valve stem 104 of the proportional regulating valve. The valve stem 104 drives the proportional regulating rod 213 to move axially along the regulating filter element 215, and the proportional regulating valve has a scale marking structure.

[0027] Specifically, this pressure equalization regulating binary mixer is suitable for mixing binary non-corrosive gases and can continuously provide binary gases with stable proportions; it has a built-in interlocking pressure equalization proportional valve, a purely pneumatic high-precision volume concentration ratio structure, and convenient adjustment of mixing ratio and outlet pressure; the structure is simple and requires no electricity.

[0028] See Figure 1 The secondary gas chamber is connected to the third gas chamber, and the secondary gas chamber is a low-pressure chamber. The third gas chamber is located above the main gas membrane 203. The main gas chamber is connected to the sixth gas chamber, and the main gas chamber is a low-pressure chamber. The sixth gas chamber is located above the secondary gas membrane 207, thereby ensuring that the pressure of the main gas and the secondary gas is equal before entering the mixing chamber, achieving zero pressure difference, which facilitates the proportional control of the subsequent binary gas mixer.

[0029] One end of the regulating tube is connected to the main gas and the other end is connected to the secondary gas. The regulating filter element 215 is separated into two parts by the proportional regulating rod 213. The main gas and the secondary gas enter the mixing chamber through the regulating filter element 215 respectively. By changing the position of the proportional regulating rod 213 in the regulating filter element 215, the flow ratio of the main gas and the secondary gas in the regulating filter element 215 can be adjusted, thereby controlling the mixing ratio of the two gases.

[0030] The valve stem 104 of the proportional control valve is connected to the proportional control rod 213. When the valve stem 104 of the proportional control valve is adjusted, the proportional control rod 213 moves together with the valve stem 104. The position of the proportional control rod 213 in the regulating filter element 215 is indicated by the scale marking structure, so as to realize the dynamic tracking of the mixing ratio.

[0031] This pressure equalization regulating binary mixer can mix two media with different pressures in the required ratio through a proportional regulating valve and a pressure equalization control valve. The two media are first adjusted to the same pressure by the pressure equalization control valve, and then the mixing ratio of the two media is adjusted by the proportional regulating valve to achieve accurate mixing of the media according to the required mixing ratio.

[0032] The working principle of the pressure equalization regulating binary mixer is explained in detail below: See Figure 1 The secondary gas chamber, i.e. the low-pressure chamber of the secondary gas, is connected to the upper part of the main gas membrane 203. The main gas chamber, i.e. the low-pressure chamber of the main gas, is connected to the upper part of the secondary gas membrane 207, thereby ensuring that the pressure of the main gas and the secondary gas is equal before entering the mixing chamber, achieving zero pressure difference.

[0033] The primary gas and the secondary gas flow into the regulating pipe from both ends. The primary gas and the secondary gas are separated by the sealing ring 214 on the proportional regulating rod 213. By changing the flow area of ​​the two gases, different proportions of mixed gas can be obtained.

[0034] The proportional control rod 213 is connected to the valve stem 104 of the proportional control valve, so that different concentrations of mixed gas can be obtained by changing the valve stem 104 of the proportional control valve.

[0035] The following is a detailed description of the structure of the pressure equalization control valve in a pressure equalization regulating binary mixer: In the optional embodiment of the present invention, the pressure equalization control valve includes a main gas sealing rod 204 and a secondary gas sealing rod 208; the main gas sealing rod 204 is slidably installed in the main gas chamber and is equipped with a main gas sealing ring 205; the front end of the main gas sealing rod 204 and the front end of the main gas sealing ring 205 constitute a first gas chamber, and the space between the main gas sealing rod 204, the main gas sealing ring 205 and the main gas diaphragm 203 constitutes a second gas chamber; the second gas chamber is connected to a sixth gas chamber; the secondary gas sealing rod 208 is slidably installed in the secondary gas chamber and is equipped with a secondary gas sealing ring 209; the front end of the secondary gas sealing rod 208 and the front end of the secondary gas sealing ring 209 constitutes a fourth gas chamber, and the space between the secondary gas sealing rod 208, the secondary gas sealing ring 209 and the secondary gas diaphragm 207 constitutes a fifth gas chamber, and the fourth gas chamber is connected to a third gas chamber.

[0036] Specifically, see Figure 2 The equalizing control valve includes a main gas end cap 202 and a secondary gas end cap 206. The main gas end cap 202 is installed on the control valve body 201 and forms a main gas chamber with the control valve body 201. A third gas chamber is formed between the main gas diaphragm 203 and the main gas end cap 202. The secondary gas end cap 206 is installed on the control valve body 201 and forms a secondary gas chamber with the control valve body 201. A sixth gas chamber is formed between the secondary gas diaphragm 207 and the secondary gas end cap 206. For more details, see [link to relevant documentation]. Figure 3The main gas and secondary gas enter the control valve body 201 from their respective inlets. The main gas enters the first chamber formed by the front end of the main gas sealing rod 204 and the main gas sealing ring 205. The second chamber is formed between the main gas sealing rod 204, the main gas sealing ring 205, and the main gas diaphragm 203. The third chamber is formed between the main gas diaphragm 203 and the main gas end cap 202. The secondary gas enters the fourth chamber formed by the front end of the secondary gas sealing rod 208 and the secondary gas sealing ring 209. The fifth chamber is formed between the secondary gas sealing rod 208, the secondary gas sealing ring 209, and the secondary gas diaphragm 207. The sixth chamber is formed between the secondary gas diaphragm 207 and the secondary gas end cap 206. The second and sixth chambers are connected. The first gas chamber is connected to the third gas chamber. When the pressure equalization regulating binary gas mixer is working, the main gas and the secondary gas enter the first gas chamber and the fourth gas chamber respectively. The fourth gas chamber is connected to the third gas chamber. The pressure at the rear end of the main gas diaphragm 203 increases, which pushes the main gas diaphragm 203 to agitate and squeeze the main gas sealing rod 204, connecting the first gas chamber to the second gas chamber. The main gas enters the sixth gas chamber from the second gas chamber. The pressure at the rear end of the secondary gas diaphragm 207 increases, which pushes the secondary gas diaphragm 207 to agitate and squeeze the secondary gas sealing rod 208, connecting the fourth gas chamber to the fifth gas chamber. In this process, through dynamic control, the pressure balance of the main and secondary gases in the second and fifth gas chambers is achieved, which facilitates the proportional control of the subsequent binary gas mixer.

[0037] In an optional embodiment of the present invention, a sealing ring 214 is installed on the proportional adjustment rod 213.

[0038] Specifically, the sealing ring 214 is fitted onto the bottom end of the proportional adjustment rod 213, and its outer wall abuts against the inner wall of the adjusting filter element 215.

[0039] The sealing ring 214 is used to divide the interior of the regulating filter element 215 into two parts, thereby separating the primary gas and the secondary gas. One end of the regulating tube is connected to the primary gas, and the other end is connected to the secondary gas. The regulating filter element 215 is separated into two parts by the proportional regulating rod 213 and the sealing ring 214. The primary gas and the secondary gas enter the mixing chamber through the regulating filter element 215 respectively. By changing the position of the proportional regulating rod 213 in the regulating filter element 215, the proportion of the primary and secondary gas flowing in the regulating filter element 215 can be adjusted, thereby controlling the mixing ratio of the two gases.

[0040] In an optional embodiment of the present invention, the control valve body 201 includes at least one closed tube, each closed tube is equipped with a filter element 211, and the closed tube is connected to the mixing chamber through the filter element 211.

[0041] Specifically, see Figure 4The pressure equalization control valve includes a sealing pipe and a regulating pipe at its rear end. The sealing pipe consists of a sealing cap 210 and a filter element 211. The sealing pipe is only connected to the main gas supply. After passing through the filter element 211, the gas enters the mixing chamber to form the main body of the mixed gas. In this embodiment, three sealing pipes are provided.

[0042] The closed tube is only connected to the main energy source, enabling the rapid entry of the main energy source and improving mixing efficiency.

[0043] In the optional solution provided by the embodiments of the present invention, the proportional adjustment rod 213 is threadedly connected to the valve stem 104.

[0044] The valve stem 104 of the proportional control valve and the proportional control rod 213 of the pressure equalization control valve are connected by threads. When the adjusting cap 101 of the proportional control valve is adjusted, the valve stem 104 and the proportional control rod 213 move up and down together. The scale wheel 111 indicates the up and down position of the proportional control rod 213 in the adjusting filter element 215, thereby realizing dynamic tracking of the mixing ratio.

[0045] See Figure 2 The equalizing control valve front end includes a control valve body 201, a main gas end cap 202, a main gas diaphragm 203, a main gas sealing rod 204, a main gas sealing ring 205, a secondary gas end cap 206, a secondary gas diaphragm 207, a secondary gas sealing rod 208, and a secondary gas sealing ring 209. See also... Figure 3 The main gas and secondary gas enter the control valve body 201 from their respective inlets. The main gas enters the first chamber formed by the front end of the main gas sealing rod 204 and the main gas sealing ring 205. The second chamber is formed between the main gas sealing rod 204, the main gas sealing ring 205, and the main gas diaphragm 203. The third chamber is formed between the main gas diaphragm 203 and the main gas end cap 202. The secondary gas enters the fourth chamber formed by the front end of the secondary gas sealing rod 208 and the secondary gas sealing ring 209. The fifth chamber is formed between the secondary gas sealing rod 208, the secondary gas sealing ring 209, and the secondary gas diaphragm 207. The sixth chamber is formed between the secondary gas diaphragm 207 and the secondary gas end cap 206. The second and sixth chambers are connected. The first and third gas chambers are connected. When the pressure-equalizing binary gas mixer is working, the primary gas and secondary gas enter the first and fourth gas chambers respectively. The fourth gas chamber is connected to the third gas chamber. The pressure at the rear end of the primary gas diaphragm 203 increases, pushing the primary gas diaphragm 203 to agitate and squeeze the primary gas sealing rod 204, connecting the first and second gas chambers. The primary gas then enters the sixth gas chamber from the second gas chamber. The pressure at the rear end of the secondary gas diaphragm 207 increases, pushing the secondary gas diaphragm 207 to agitate and squeeze the secondary gas sealing rod 208, connecting the fourth and fifth gas chambers. During this process, dynamic control is used to achieve pressure balance between the primary and secondary gases in the second and fifth gas chambers, facilitating the proportional control of the subsequent binary gas mixer. See also Figure 4The equalizing control valve includes a closed tube and a regulating tube at its rear end. The closed tube includes a sealing cap 210 and a filter element 211, while the regulating tube includes a regulating cap 212, a proportional regulating rod 213, a sealing ring 214, and a regulating filter element 215. The closed tube is only connected to the main gas source and enters the mixing chamber after passing through the filter element 211, forming the main body of the mixed gas. One end of the regulating tube is connected to the main gas source, and the other end is connected to the secondary gas source. The regulating filter element 215 is separated into two parts by the proportional regulating rod 213 and the sealing ring 214. The main gas source and the secondary gas source enter the mixing chamber through the regulating filter element 215 respectively. By changing the position of the proportional regulating rod 213 in the regulating filter element 215, the flow ratio of the main gas source and the secondary gas source in the regulating filter element 215 can be adjusted, thereby controlling the mixing ratio of the two gases.

[0046] The valve stem 104 of the proportional control valve and the proportional control rod 213 of the pressure equalization control valve are connected by threads. When the adjusting cap 101 of the proportional control valve is adjusted, the valve stem 104 and the proportional control rod 213 move up and down together. The scale wheel 111 indicates the up and down position of the proportional control rod 213 in the filter element 211, thereby realizing dynamic tracking of the mixing ratio.

[0047] The following is a detailed description of the structure of the proportional control valve in a pressure equalization regulating binary mixer: Among the optional solutions provided in the embodiments of the present invention, see [link to relevant documentation]. Figure 5 The proportional control valve includes a control valve body 105, a control rod 103, and a control cap 101. One end of the control rod 103 extends into the control valve body 105 and is screwed onto the valve stem 104, while the other end is fitted with the control cap 101. The end of the valve stem 104 away from the control rod 103 extends out of the control valve body 105 and is connected to the proportional control rod 213. The valve stem 104 and the control valve body 105 are in sliding fit, and the valve stem 104 can move axially along the control valve body 105.

[0048] Specifically, the proportional control valve includes a valve cover 102, a control valve body 105 and a valve cover 102 are assembled by a first screw 107, a control cap 101 is mounted on the outside of the valve cover 102, the control cap 101 has a square hole inside that fits with the square tenon at the upper end of the control rod 103, and is fixed to the control rod 103 by a second screw 106, and the control rod 103 is connected to the valve stem 104 by threads.

[0049] When the adjusting cap 101 is driven, the adjusting cap 101 is connected to the adjusting rod 103, so the adjusting rod 103 is driven to rotate; the valve rod 104 is screwed to the adjusting rod 103 and slides with the adjusting valve body 105, so that the valve rod 104 is driven to move up and down when the adjusting rod 103 rotates.

[0050] In the optional solution provided by the embodiments of the present invention, the proportional regulating valve includes a scale wheel 111, which is connected to the valve stem 104 in a transmission manner, and the scale wheel 111 is provided with a scale marking structure.

[0051] The scale wheel 111 has corresponding data. When the indicated data needs to be adjusted, the external square tenon of the adjusting cap 101 is clamped by the tool and rotated axially. The adjusting cap 101 is fixed with the adjusting rod 103, which drives the adjusting rod 103 to rotate. Since the valve stem 104 and the sliding hole of the adjusting valve body 105 restrict the rotation, it will move up and down under the action of the thread, which in turn drives the transverse gear 108 to rotate along the gear shaft 109 and the scale wheel 111, indicating the corresponding scale data.

[0052] Among the optional solutions provided in the embodiments of the present invention, see [link to relevant documentation]. Figure 6 The proportional control valve includes a gear shaft 109 and a gear 108; both the gear 108 and the scale wheel 111 are mounted on the gear shaft 109 and are spaced apart along the axial direction of the gear shaft 109, and the axial direction of the gear shaft 109 is perpendicular to the axial direction of the valve stem 104; the valve stem 104 meshes with the gear 108.

[0053] Specifically, both gear 108 and scale wheel 111 are fixedly mounted on gear shaft 109 and can rotate with gear shaft 109.

[0054] The valve stem 104 engages with the transverse gear 108. The gear 108 and the scale wheel 111 are fixed to the gear shaft 109 by the set screw 110. The scale wheel 111 has corresponding data. When the indicated data needs to be adjusted, the external square tenon of the adjusting cap 101 is clamped by the tool and rotated axially. The adjusting cap 101 is fixed to the adjusting rod 103, which drives the adjusting rod 103 to rotate. Since the valve stem 104 is engaged with the sliding hole of the regulating valve body 105 to restrict rotation, it will move up and down under the action of the thread, thereby driving the transverse gear 108 to rotate along the gear shaft 109 and the scale wheel 111, indicating the corresponding scale data.

[0055] In an optional embodiment of the present invention, the regulating valve body 105 is provided with a sliding hole, the cross-sectional shape of the sliding hole is polygonal, and the cross-sectional shape of the valve stem 104 corresponding to the sliding hole is adapted to the cross-sectional shape of the sliding hole.

[0056] Specifically, the lower end of the valve stem 104 is a square tenon, which is assembled with the square sliding hole of the regulating valve body 105 to restrict rotation, thereby realizing the transmission from the rotation of the regulating cap 101 to the up and down movement of the valve stem 104.

[0057] The proportional control valve includes an adjusting cap 101, a valve cover 102, a control valve body 105, a valve stem 104, a gear 108, a gear shaft 109, a scale wheel 111, a second screw 106, a first screw 107, and a set screw 110. (See also...) Figure 5The regulating valve body 105 and valve cover 102 are assembled by a first screw 107. An adjusting cap 101 is mounted on the outside of the valve cover 102. The adjusting cap 101 has a square hole inside that engages with a square tenon at the upper end of the adjusting rod 103, and is fixed to the adjusting rod 103 by a second screw 106. The adjusting rod 103 is connected to the valve stem 104 by threads. The lower end of the valve stem 104 has a square tenon that is assembled with the regulating valve body 105 to restrict rotation, thus realizing the transmission from the rotation of the adjusting cap 101 to the up-and-down movement of the valve stem 104. (See also...) Figure 6 The valve stem 104 engages with the transverse gear 108. The gear 108 and the scale wheel 111 are fixed to the gear shaft 109 by the set screw 110. The scale wheel 111 has corresponding data. When the indicated data needs to be adjusted, the external square tenon of the adjusting cap 101 is clamped by the tool and rotated axially. The adjusting cap 101 is fixed to the adjusting rod 103, which drives the adjusting rod 103 to rotate. Since the valve stem 104 is engaged with the sliding hole of the regulating valve body 105 to restrict rotation, it will move up and down under the action of the thread, thereby driving the gear 108 to rotate along the gear shaft 109 and the scale wheel 111, indicating the corresponding scale data.

[0058] The following is a detailed description of the other structures in the pressure equalization regulating binary mixer: In the optional solution provided by the embodiments of the present invention, the pressure equalization regulating binary mixer includes a housing, and a proportional regulating valve and a pressure equalization control valve are both installed in the housing.

[0059] Specifically, the enclosure adopts a stainless steel water tank structure to prevent damage to the equipment from external forces, and can be directly installed indoors. The enclosure has a panel on which the main gas pressure gauge, secondary gas pressure gauge, and mixed gas pressure gauge are installed to display the main gas inlet pressure, secondary gas inlet pressure, and mixed gas outlet pressure. A regulating valve is also installed on the panel. The mixed gas is regulated to the gas pressure required by the equipment before being supplied to the workshop pipeline.

[0060] The following are the instructions for use of the pressure equalization regulating binary mixer: Filters are installed at the air inlets of both the primary and secondary air sources.

[0061] Connect the two input gas inlets of the pressure equalizing and regulating binary mixer to the gas source according to the markings, and connect the outlet of the pressure equalizing and regulating binary mixer to the mixed gas outlet system. The inlet and outlet ports are marked with labels.

[0062] Confirm the inlet pressure of the primary energy and the inlet pressure of the secondary energy, while ensuring that the pressure of the primary energy is higher than that of the secondary energy.

[0063] First, open the main energy intake valve. If there are no abnormalities, then open the secondary energy intake valve. Adjust the mixing concentration using the proportional control valve.

[0064] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.
