[0034] By setting the vibration-damping balloon 20, during use, the vibration-damping balloon 20 will come into contact with the outer wall of the pipe connected to the connecting flange. When the flow of the connected pipe is too large, the vibration-damping balloon 20 will initially reduce vibration, and then the vibration-damping balloon 20 will cooperate with the connecting arm 18 and the guide slider 17 to transfer the potential energy to the vibration absorber 16, and then the potential energy will be absorbed by the vibration absorber 16, so as to effectively weaken the vibration caused by the flow in the pipe connected to the connecting flange.

[0035] like Figure 1 and Figure 2 As shown, the bottom end of the double-chamber solenoid valve body 1 is fixedly connected to the top end of the mounting seat 2, and both ends of the mounting seat 2 are provided with an active cavity 3 with an inner wall having a "convex" structure, and the interior of the active cavity 3 is movably connected with an extension plate 4 with a "convex" structure.

[0036] By setting the extension plate 4, during use, the upper fixed frame 11 and the lower fixed frame 10 set at the top of the extension plate 4 can be adjusted according to the stress condition of the double-chamber solenoid valve body 1 through the movement of the extension plate 4.

[0037] like Figure 1 and Figure 2As shown, the bottom end of the mounting base 2 is symmetrically fixedly connected with a connecting plate 8, and a driving knob 7 for driving the transmission screw 6 to rotate synchronously is arranged between the corresponding outer side walls of the connecting plate 8, both ends of the driving knob 7 are fixedly connected with the transmission screw 6, and the other end of the transmission screw 6 is movably connected to one side of the connecting plate 8, the outer side wall thread structure of the two transmission screws 6 is arranged in opposite structures, the outer side wall of the transmission screw 6 is meshingly connected with a connecting screw sleeve 5, and the top end of the connecting screw sleeve 5 is fixedly connected to the bottom end of the adjustment extension plate 4.

[0041] Principle and process of this utility model:

[0042] Firstly, during use, the operator can turn the driving knob 7 forward or reversely, thereby driving the transmission screw 6 fixedly connected at both ends to rotate synchronously, and then the transmission screw 6 and the engaged connecting screw sleeve 5 form a screw transmission, and finally adjust the extension of the extension plate 4 according to the different force conditions of the double-chamber solenoid valve body 1.

[0043] Secondly, the lower fixed frame 10 and the upper fixed frame 11 are installed on the outer wall of the connected pipeline, and then the lower fixed frame 10 and the upper fixed frame 11 are fixed to each other by screws, so that the lower fixed frame 10 and the upper fixed frame 11 are fixedly connected to the connected pipeline, and then the whole device is fixed, and after the connection and fixation, the sound insulation cotton 12 is used to effectively improve the sound insulation effect of the connected pipeline.

[0044] Afterwards, the required connected pipe is connected and fixed to the corresponding connection port through the connecting flange. Finally, when the device is in working state, the shock-absorbing balloon 20 will resist the outer wall of the pipe connected to the connecting flange. When the flow of the connected pipe is too large, the shock-absorbing balloon 20 will absorb the vibration and complete the initial vibration reduction. The potential energy is then transferred to the shock absorber 16 through the shock-absorbing balloon 20 in cooperation with the connecting arm 18 and the guide slider 17, and the potential energy is then absorbed by the shock absorber 16. Finally, the vibration generated by the flow in the pipe connected to the connecting flange is effectively weakened, and a dual-chamber solenoid valve that is universal for water and gas is completed.
