[0024] When in use, first connect the end of the solenoid valve body 1 away from the low-temperature resistant telescopic tube 2 with one of the pipe threads. The setting of the low-temperature resistant telescopic tube 2 makes it convenient to adjust the position of the end of the low-temperature resistant telescopic tube 2 away from the solenoid valve body 1, and conveniently connect it with the other pipe thread. Loosen the two fastening bolts 14, pull out the two clamping blocks 5, and after the pipe connected to the low-temperature resistant telescopic tube 2 is located between the two clamping blocks 5, tighten the two fastening bolts 14 and the two connecting bolts 51. The two clamping blocks 5, the sleeve 4, and the socket 3 cooperate to improve the stability of the solenoid valve body 1, thereby solving the problem that it is not conducive to the installation of the ultra-low temperature direct-acting solenoid valve when the length of the ultra-low temperature direct-acting solenoid valve is less than the distance between the connection between the two pipes.

The arrangement of the low-temperature resistant telescopic tube 2 facilitates the adjustment of the position of the end of the low-temperature resistant telescopic tube 2 away from the solenoid valve body 1, and facilitates the connection with another pipe thread.

[0031] Loosen the two fastening bolts 14, pull out the two clamping blocks 5, and after the pipe connected to the low-temperature resistant telescopic pipe 2 is located between the two clamping blocks 5, tighten the two fastening bolts 14 and the two connecting bolts 51. The two clamping blocks 5, the sleeve 4, and the holder 3 cooperate to improve the stability of the solenoid valve body 1, thereby solving the problem that it is not conducive to the installation of the ultra-low temperature direct-acting solenoid valve when the length of the ultra-low temperature direct-acting solenoid valve is less than the distance between the two pipes.

[0032] By rotating the threaded sleeve 9, the position of the base 10 can be adjusted according to the distance between the solenoid valve body 1 and the ground or equipment. The base 10 is close to the ground or equipment. The support 8 can support the solenoid valve body 1 to prevent the solenoid valve body 1 from shaking due to the solenoid valve body 1 being suspended in the air and affecting the sealing of the pipeline connection.
