And the left second one-way valve 104a and the right second one-way valve 104b are fixedly installed in the pipe wall of the horizontal circular pipe of the cylinder body 101, the left second one-way valve 104a is positioned on the left side of the left first one-way valve 103a, the right second one-way valve 104b is positioned on the right side of the right first one-way valve 103b, the air inlet is communicated with the inner cavity of the cylinder body 101, and the air outlet 104e of the second one-way valve is communicated with the communicating air passage 105.
Working process
The pipeline is installed in pipeline bracket 4, and when the pipeline takes place vibrations, pipeline bracket 4 takes place the small amplitude and moves to returning, and the transmission through dwang 302, transfer line 301 and piston rod 107 will shake and transmit piston 102, and piston 102 is reciprocating motion in cylinder body 101, turns into internal energy with kinetic energy through air compression, realizes the stability of pipeline.
When the length of the pipeline is changed due to the influence of the environment, the pipeline frame 4 is displaced in a single direction to a large extent, and the change is transmitted to the piston 102 through the transmission of the rotating rod 302, the transmission rod 301 and the piston rod 107. When the deformation amount is large enough, when the pressure of one side of the piston 102 meets the pressure of opening the second one-way valve 104, the second one-way valve 104 is opened, so that the gas at the side with large pressure in the cylinder 101 flows to the side with small pressure of the cylinder 101 through the second one-way valve 104 and the first one-way valve 103 at the side with small pressure through the communicating air passage 105, the gas pressure difference value at the two sides of the piston 102 is reduced, most of the constant force added on the buffer is eliminated, the force for promoting the relative movement of the pipe frame 4 and the pipe is almost not generated, and the service lives of the two are prolonged.
Specifically, for example, when the pipeline is lengthened to cause the piston 102 to move rightward, the gas pressure on the right side of the piston 102 reaches the working value of the right second check valve 104b, and the right gas enters the left side of the piston 102 through the right second check valve 104b, the communication gas passage 105, the left first check valve 103a and the left gas inlet passage 106a in sequence. After the left end surface of the piston 102 passes over the right first check valve 103b, if the piston continues to move to the right, when the gas pressure on the right side of the piston 102 reaches the working pressure of the right second check valve 104b again, the gas on the right side of the piston 102 can flow to the left side of the piston 102 through the left first check valve 103a and the right first check valve 103 b.
The second check valve 104 may vary the pre-load of the spring by varying the position of the threaded regulator 104d, thereby controlling the effect of the operating pressure of the second check valve 104.
