[0075] The threaded cylinder 321 is provided with a on-off valve 322 at the bottom of the outer curved surface, the on-off valve 322 is provided with a three-way pipe 323 at the end, the push cavity 304 is directly communicated with the booster cavity 308, the end face area of the large circular plug 305 is larger than that of the small circular plug 307, the booster cavity 308 is communicated with the shunt box 302 through the air conveying valve 311 and the flat pipe 312, the air conveying valve 311 and the air conveying valve 313 are both one-way valves, and the space between the partition plate 223 and the sliding block 225 in the box body 221 is connected with the on-off valve 322 through the three-way pipe 323, so as to limit the ring pressure threshold value.

[0076] The working principle and use process of the present application are as follows: before using the installation construction method to install the ring pressure type connection of the thin-walled stainless steel water pipe, first, the external cylindrical sealing material is sleeved on the pipe material 11, and the pipe material 11 is inserted into the pipe fitting 12 together with the external cylindrical sealing material, so that the external cylindrical sealing material is clamped into the sealing section cavity of the pipe fitting 12, and the ring pressure connection between the water pipes can be fixed in sequence according to the actual construction requirements, that is, the ring pressure connection between the water pipes can be fixed one by one, or the ring pressure connection between the water pipes can be fixed uniformly after the preliminary arrangement and installation of each pipe material 11 and pipe fitting 12 are completed.

[0077] During the ring pressure connection and fixation process between the water pipes, first, the size specifications of the clamp seat 201 and the support 202 are selected according to the size of the water pipes to be ring pressure connected and fixed, and then the mounting base 1 is connected and fixed with the machine body 301 through the threaded ring 303 and the threaded cylinder 321, then the on-off valve 322 is opened, and the air pump 31 is started through the switch 35, the external air is filtered by the filter head 32 and then sent into the shunt box 302, in the initial state, the airflow flows into the booster cavity 308 through the flat pipe 312, and then flows into the box body 221 through the air conveying valve 313 and the air conveying port 228, and then flows into the guide cavity 215 through the connecting pipe 216, and then flows into each air cylinder 203 and air cylinder 210, so as to accumulate the initial air pressure.

[0078] Subsequently, the small plug 307 will push the large plug 305 to the side of the air pump 31 under the action of air pressure through the column 306, and at the same time, under the guidance of the cannula 319, the air inside the push chamber 304 between the large plug 305 and the shunt box 302 will be compressed into the sliding chamber 314 through the cannula 319, forcing the sliding cylinder 315 to slide to the side of the threaded ring 303, so that the top hole 317 and the curved hole 318 are in communication, and the air between the large plug 305 and the shunt box 302 will flow into the gap between the large plug 305 and the small plug 307 through the curved hole 318;

[0079] As the small plug 307 continuously displaces to the side of the large plug 305 under the action of air pressure, air continuously fills the booster chamber 308, and after the small plug 307 moves to the end of the booster chamber 308, the ring groove 310 will be in communication with the space on the other side of the small plug 307, that is, the space inside the booster chamber 308 between the air supply valve 313 and the small plug 307 will be in communication with the ring groove 310, at this time the airflow will enter the sliding chamber 314 through the ring groove 310, and since the small plug 307 displaces to the side of the large plug 305, it is known that the air pressure inside the booster chamber 308 between the air supply valve 313 and the small plug 307 is greater than the air pressure inside the push chamber 304 between the large plug 305 and the shunt box 302;

[0080] At this time, under the action of the pressure difference, the sliding cylinder 315 displaces to the side of the large plug 305, causing the top hole 317 and the curved hole 318 to be out of position and closed, while the bottom hole 316 is in communication with the shunt pipe 320, at this time the airflow sent by the air pump 31 into the shunt box 302 will enter the sliding chamber 314 through the shunt pipe 320 and the bottom hole 316, and then enter the space inside the push chamber 304 between the large plug 305 and the shunt box 302 through the cannula 319, forcing the large plug 305 to push the small plug 307 to displace to the side of the air supply valve 313 under the action of air pressure through the column 306;

[0081] In the initial state, the ring groove 310 is in communication with the gap between the large plug 305 and the small plug 307, and after the small plug 307 continuously displaces, the ring groove 310 will again be in communication with the gap between the large plug 305 and the small plug 307, and since the large plug 305 displaces to the side of the small plug 307, it is known that the air pressure inside the push chamber 304 between the large plug 305 and the shunt box 302 is greater than the air pressure between the large plug 305 and the small plug 307;

[0082] Under the guidance of the cannula 319, the air pressure inside the push chamber 304 between the large plug 305 and the shunt box 302 will act on the sliding cylinder 315, forcing the sliding cylinder 315 to displace to the side of the small plug 307 under the action of air pressure, returning to the initial position, at this time the top hole 317 will again be in communication with the curved hole 318, returning to the initial position, and the small plug 307 will again push the large plug 305 to displace to the side of the shunt box 302 under the action of air pressure;

[0083] So the cycle, in the small plug 307 and the large plug 305 reciprocating displacement process, extrusion pump 31 into the air chamber 308 of the airflow, using the end face difference of the small plug 307 and the large plug 305 to cycle air pressure, resulting in the output of the gas valve 313 gas pressure rising, under the conduction of on-off valve 322 and three-way pipe 323, the gas flow will also be synchronized into the box 221 between the partition plate 223 and the slider 225 gap, here can be according to the actual demand, according to the pressure gauge 33, the slider 225 end face of the gas pressure is limited, the gas pressure is the ring pressure threshold value in the process of ring pressure connection and fixation;

[0084] In the slider 225 end face of the gas pressure reaches the required ring pressure threshold value, close the on-off valve 322, and then close the air pump 31, complete the ring pressure threshold value limiting work, then open the relief valve 24 on the support 202, and then discharge, under the communication of the shaft pipe 224 and the through slot 226, and the flow limiting effect of the check valve 222, the gas flow in the guide cavity 215 in the clamp seat 201 can flow to the guide cavity 215 in the support 202, at this time, open the relief valve 24 on the support 202, can simultaneously discharge the gas flow in each guide cavity 215, according to the pressure gauge 33, according to the actual situation, discharge the corresponding amount of gas flow, limit the initial gas pressure in the cylinder 203 and the air cylinder 210, to give the initial support force to the water pipe;

[0085] Then reverse rotation bolt 23, remove the limit of the ear plate 22, so that the clamp seat 201 and the support 202 can be freely opened, pull the limiting rod 21, synchronously open the clamp seat 201 and the support 202, clamp the clamp seat 201 and the support 202 on the outside of the water pipe, and then put down the limiting rod 21, so that the clamp seat 201 and the support 202 reset and close, then rotate the bolt 23, so that it presses against the ear plate 22, so that the clamp seat 201 and the support 202 cannot be opened, at this time, under the action of the gas pressure in the air cylinder 210, the top plate 212 will push the limiting head 214 through the top rod 213, so that the limiting head 214 on the two supports 202 respectively abuts against the pipe 11 and the pipe fitting 12, giving the initial support force to the water pipe, and preliminarily correcting the orientation of the pipe 11 and the pipe fitting 12 relative to the ring pressure head 204;

[0086] Then push the pipe 11 and the pipe fitting 12 along the axial direction of the water pipe, further correct the orientation of the pipe 11 and the pipe fitting 12 relative to the ring pressure head 204, so that the ring pressure head 204 abuts against the pipe 11 and the pipe fitting 12 at the connection part of the pipe 11 and the pipe fitting 12, and under the action of the gas pressure in the cylinder 203, the push plate 205 will push the push rod 206, forcing the ring pressure head 204 to abut against the pipe 11 and the pipe fitting 12 at the connection part of the pipe 11 and the pipe fitting 12;

[0087] In this process, under the communication of the communication pipe 220, the air flow inside the guide cavity 215 in the support 202 will flow into the cylinder 217 synchronously, forcing the two stop plates 219 to drag the two supports 202 through the pull rod 218 under the action of air pressure, so that the two supports 202 keep close to each other, and further apply the force to the pipe material 11 and the pipe fitting 12 through the limiting head 214, so that the pipe material 11 and the pipe fitting 12 keep the inserted and connected state during the positioning process. The aforementioned positioning of the pipe material 11 and the pipe fitting 12 is the state in which the pipe material 11 and the pipe fitting 12 can be positioned. After the preliminary arrangement and installation of each pipe material 11 and pipe fitting 12 is completed, i.e. in the state in which the pipe material 11 and the pipe fitting 12 cannot be positioned, the movable clamp holder 201 and the support 202 can be selected;

[0088] Then the air pump 31 is started, and the air flow is sent into the air cylinder 203 and the air cylinder 210 again after being pressurized. Under the action of air pressure, each limiting head 214 on the two supports 202 will lock the pipe fitting 12 and the pipe material 11 respectively, and fix the relative position. Each ring pressure head 204 outside the pipe fitting 12 will extrude the pipe fitting 12, forcing the pipe fitting 12 to tightly clamp the pipe material 11. With the continuous rise of air pressure, the outer diameter of the pipe fitting 12 is forced to shrink, so that the pipe fitting 12 is embedded into the pipe material 11, forming a thread-like engagement effect;

[0089] After the air pressure reaches the ring pressure threshold, the air pressure inside the box body 221 between the two stop plates 219 is sufficient to offset the air pressure on the other side of the two stop plates 219, so as to drive the two stop plates 219 to move away. At this time, the relief port 227 is in communication with the space between the two stop plates 219 inside the box body 221, and the excess air flow is discharged through the relief port 227, so as to prevent the air pressure inside the air cylinder 203 from exceeding the air pressure threshold, realize automatic pressure maintaining, and then stop the air pump 31, complete the preliminary ring pressure of the water pipe;

[0090] Then the relief valve 24 on the clamp holder 201 is opened, and the air flow inside the guide cavity 215 in the clamp holder 201 is discharged, reducing the air pressure inside the air cylinder 203, so that the ring pressure head 204 no longer tightly presses the pipe fitting 12 and can be displaced relative to the pipe fitting 12. At the same time, under the flow limiting of the check valve 222, the air inside the guide cavity 215 in the support 202 cannot flow reversely into the guide cavity 215 in the clamp holder 201, i.e. the air inside the guide cavity 215 in the support 202 cannot be discharged through the relief valve 24 on the clamp holder 201, and the pipe material 11 and the pipe fitting 12 are still locked by the limiting head 214 and cannot be displaced relative to each other;

[0091] At this time, the jaw seat 201 and the support 202 are rotated, and under the driving of the support 202 and the limiting action of the limiting head 214, the arc plate 209 will slide and deflect relative to the jaw arm 208, and the ring pressing head 204 will also deflect relative to the pipe 12 under the driving of the jaw seat 201. After the jaw seat 201 and the support 202 are rotated to the limit position, i.e., after the arc plate 209 abuts against the jaw arm 208, the air pump 31 is started again, and each ring pressing head 204 on the outside of the pipe 12 will press the pipe 12 again to perform the second-stage compensation ring pressing;

[0092] After the air pressure reaches the ring pressing air pressure threshold, the air pump 31 is turned off, and then the pressure relief valve 24 on the support 202 is opened, the gas in the air cylinder 203 and the air cylinder 210 is discharged, the bolt 23 is reversely rotated to release the limiting of the lug plate 22, so that the jaw seat 201 and the support 202 can be freely opened, the jaw seat 201 and the support 202 are taken off from the outside of the water pipe, and the ring pressing work of the water pipe is completed.

[0093] During the entire ring pressing process, the limiting head 214 will be locked with the pipe material 11 and the pipe 12, and under the pulling of the pull rod 218, the pipe material 11 and the pipe 12 will be kept in displacement driving, so that the misplacement of the pipe material 11 and the pipe 12 during the ring pressing process can be avoided. The ring pressing pressure of each ring pressing head 204 directly comes from the air pressure in each air cylinder 203, the flow of the gas can be fully utilized, the ring pressing pressure is more uniform, the wear error of the ring pressing head 204 during the working process can be compensated by adjusting the position of the ring pressing head 204, and the ring pressing head 204 can be suitable for the ring pressing work of the water pipe with different diameters.
