At this time, the limiting pin 121 is located at the connection position between the mounting hole 211 and the first slope 213, then the mounting ring 210 is manually rotated, so that the mounting ring 210 rotates relative to the limiting pin 121, the limiting pin 121 slides along the first slope 213, and does not continue to rotate until the limiting pin 121 is located at the flat slope 214, during the process that the limiting pin 121 passes from the first slope 213 to the flat slope 214, the mounting ring 210 is promoted to move towards one side close to the sealing gasket, the pressure between the mounting ring 210 and the sealing gasket is increased, at this time, the state when the pipeline 200 is not in use, namely, the pressure between the mounting ring 210 and the sealing shell 113 is a first preset value, at this time, the sealing disc 220 and the protrusion 118 form a sealing state through the sealing gasket, and the sealing shell 113 and the two mounting rings 210 are in a tight-pushing state, namely, no water leakage occurs during water inflow. The other pipe 200 is then installed according to the principles described above, completing the connection between the two pipes 200.
When irrigation is needed, the valve of the irrigation equipment is started, water is fed into the pipeline 200, when irrigation is carried out through water feeding in the pipeline 200, water pressure in the pipeline 200 is high, at the moment, water flows into the first cavity 123 from the water inlet 114 after passing through the pipeline 200, and then the two sliding blocks 111 are driven to rotate in the first cavity 123, air between the sliding blocks 111 and the partition plate 120 is compressed, air pressure generated by air compression pushes against the air plug, the air plug is pushed out of the communication hole 115, the first cavity 123 is communicated with the second cavity 116, the adjusting block 117 is further driven to rotate by air pressure in the second cavity 116, the adjusting block 117 is driven to rotate, the pushing block 216 is driven to rotate, the mounting ring 210 is driven to rotate on the pipeline 200, the limiting pin 121 is driven to rotate to the second slope 215 in the first direction, the limiting pin 121 moves to one side close to the sealing gasket in the process of the second slope 215 from the flat slope 214, the pressure between the mounting ring 210 and the sealing gasket is increased, and at the moment, the pressure between the mounting ring 210 and the sealing shell 113 is a second preset value. At this time, the pressure between the limiting plate 220 and the bulge 118 is increased, the sealing shell 113 and the two mounting rings 210 are further tightly propped against each other, the pressure between the sealing shell 113 and the two mounting rings 210 is increased when water is fed, and the situation that water leakage is possibly caused at the joint due to the opening and closing of the pipeline 200 when water is fed is prevented. That is, when the installation of the pipe 200 is completed and not used, the pressure between the installation ring 210 and the sealing shell 113 is a first preset value, when the pipe 200 is used, the pressure between the installation ring 210 and the sealing shell 113 is increased from the first preset value to a second preset value, and the pressure between the connection parts when the pipe 200 is not used, that is, the pressure between the installation ring 210 and the sealing shell 113 is reduced through an adjustable connection mode, so that real-time adjustment is realized.
When the irrigation equipment is closed and the pipeline 200 is not filled with water, the water pressure in the pipeline 200 is reduced at this time, the first spring 112 cannot be continuously pressed, the first spring 112 is reset, the third spring drives the adjusting block 117 to return to the initial position, the adjusting block 117 rotates to drive the pushing block 216 to rotate through the tension spring, the mounting ring 210 is further driven to rotate on the pipeline 200, the limiting pin 121 returns to the flat slope 214 from the second slope 215, and the mounting ring 210 is driven to move to the side far away from the sealing gasket in the process that the limiting pin 121 returns to the flat slope 214 from the second slope 215, so that the pressure between the mounting ring 210 and the sealing shell 113 returns to the first preset value again.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
