Embodiment Construction

[0010] As shown in Figure 1, the regulator consists of a coarse adjustment handle 1, a fine adjustment knob 2, a gearbox 3, and an output interface 4. The coarse adjustment handle 1, fine adjustment knob 2, and output interface 4 are installed on the gearbox 3, and the speed change The box 3 is composed of a gearbox body 6 and a speed change mechanism. The speed change mechanism is installed in the gearbox body 6. End covers 5 and 7 are installed on both sides of the gearbox body 6 to form a gearbox body. The worm gear is installed in the gearbox body 6 through a bearing 10. 8. A shaft sleeve 16 is installed inside the worm gear 8, and an adjustment rod 13 is installed inside the shaft sleeve 16. One end of the adjustment rod 13 extends out of the end cover 5 on the side of the gearbox body 6 to connect with the air drum 14, and the outside of the air drum 14 is installed with the end cover 5 The connected air drum protection sleeve 15, the two output ports 4 installed on the a...

Abstract

A pressure regulator installs thick regulating handle on the transmission, thin tuning knob and output interface, transmission gear mechanism installed inside the transmission box, end covers installed at both sides of the transmission box, turbines inside the transmission box installed by bearings, axle sleeves with tuning rod inside the turbine, with one end of the tuning rod connected with the gas heave by the output interface, the other end of the tuning rod connected to the thick regulating handle, worm fitting with the turbine inside the transmission box, with the worm installed inside the transmission box, the other end installed with thin tuning knob. The volume type pressure making design has long stable output pressure, and reduces the signal wave due to pressure inertia.

Description

technical field [0001] The present invention relates to instruments and meters, in particular to pressure regulators. Background technique [0002] Various outburst prevention instruments such as gas outburst parameter meters or outburst risk forecasters are indispensable and important equipment for preventing gas disasters in coal mine enterprises. , there are no inspection and calibration instruments and special optional pressure regulators. Contents of the invention [0003] The purpose of the present invention is to provide a pressure regulator, which is a micro pressure signal generating instrument, has coarse and fine adjustment functions, stable output pressure, high adjustment fineness, and is matched with a digital pressure gauge. The standard indication value is used as a reference standard. It is used for checking and calibrating the performance of anti-burst equipment, and improves the safety factor of anti-burst equipment. [0004] The technical solution of ...
