[0020] See also Figure 1-3 The utility model provides a technical solution: a height valve with an overflow mechanism, according to Figure 1 , Figure 2 and Figure 3 As shown, an air intake passage is provided in the middle of the top of the upper end of the valve body 1, and an air intake connection assembly 2 is provided inside the air intake passage, the air intake connection assembly 2 includes an air intake connector, an air intake hole 201 is provided in the middle of the outer end of the air intake connector, and the bottom of the lower end of the air intake hole 201 is connected to a storage cavity, and a one-way valve 202, a second spring 203 and a vent valve seat 204 are sequentially provided inside the storage cavity from top to bottom, and the middle of the upper end of the vent valve seat 204 is connected to the one-way valve 202 through the second spring 203. 02 is elastically connected, and the upper side of the vent valve seat 204 is detachably connected to the outer side of the lower end of the storage cavity. When the pressure of the air inlet hole 201 is relatively high, the air flow pushes open the one-way valve 202 from the air inlet hole 201 and flows into the interior of the valve body 1. At the same time, air outlet channels 101 are symmetrically arranged on both sides of the middle of the valve body 1, and an air outlet connector 102 is arranged inside the outer end of the air outlet channel 101, and the air outlet connector 102 is connected to the corresponding airbag, which is convenient for inflating the airbag and lifting the vehicle body.

[0021] according to Figure 1 , Figure 2 and Figure 3As shown, the valve body 1 is made of engineering plastic, and the valve body 1 is symmetrically provided with a first mounting guide cylinder 103 on the inner side of the upper ends of the two air outlet channels 101, and the valve body 1 is symmetrically provided with a second mounting guide cylinder 104 on the inner side of the lower ends of the two air outlet channels 101, and the first mounting guide cylinder 103 and the second mounting guide cylinder 104 are both connected to the frame or the vehicle body, and a valve seat 3 is provided at the bottom of the lower end of the valve body 1, and an exhaust port is provided at the bottom of the lower end of the valve seat 3, and a dustproof net cover is provided inside the exhaust port, and a rotating shaft structure 4 is provided on the front side of the valve seat 3, and the rotating shaft structure 4 is connected to the vehicle axle 6 through a control rod 5, and the middle of the valve body 1 is provided in sequence. There are a first spring 7, a piston valve seat 8, a piston 9 and a guide sleeve 10, and the upper end of the piston valve seat 8 is connected to the lower end of the intake connection assembly 2 through the first spring 7, and a piston 9 is arranged at the bottom of the lower end of the piston valve seat 8. The piston valve seat 8 is made of rubber, and a sealing gasket is sleeved on the outer side of the piston valve seat 8, and the outer side of the sealing gasket is in contact with the inner wall of the valve body 1. The lower end of the piston 9 passes through the guide sleeve 10 and is connected to it, and the guide sleeve 10 is connected to the rotating shaft structure 4. The middle of the piston 9 is hollow, and a middle through hole 901 is arranged in the middle of the piston 9.

[0022] When in use, it is first connected to the frame or body through the first mounting guide cylinder 103 and the second mounting guide cylinder 104, and then the shaft structure 4 is connected to the vehicle axle 6 through the control rod 5. When the load increases and the height of the vehicle body decreases, the control rod 5 adjusts the angle to drive the shaft structure 4 to rotate, so that the driving rod arranged inside the shaft structure 4 squeezes the guide sleeve 10, so that the guide sleeve 10 moves linearly inside the valve seat 3, and then the piston 9 moves to the side of the intake channel, so that the piston 9 pushes open the piston valve seat 8, and at the same time opens the one-way valve 202, so that the compressed air in the intake hole 201 flows into the valve body 1, and flows into the connection between the valve body 1 and the outlet channel 101 through the gap between the piston valve seat 8 and the inside, so that the gas inflates the connected airbag through the outlet joint 102, so that the height of the vehicle body increases. When the load decreases and the height of the vehicle body drops, the control rod 5 adjusts the angle to drive the shaft structure 4 to rotate, so that the extrusion pressure of the drive rod arranged inside the shaft structure 4 on the guide sleeve 10 is reduced, and the guide sleeve 10 retreats, so that the piston 9 retreats and disengages from the piston valve seat 8. Then, the piston valve seat 8 closes the inside of the valve body 1 under the action of the first spring 7, so that the middle through hole 901 opened by the piston 9 opens, and the compressed air inside the airbag flows out through the gap into the middle through hole 901, and then is discharged from the side hole 902 opened by the piston 9 to the valve seat 3, and is discharged from the exhaust port arranged on the valve seat 3 after being filtered by the dustproof mesh cover.
