Two-channel fine-tuning sectional valve

Abstract

A double-channel fine adjusting sectioning valve comprises an air inlet channel, a pressure stabilization valve body, a pressure stabilization valve core assembly, a stop valve assembly, an inner shell, two fan-shaped counter bored holes, inner air outlet channels, two fan-shaped adjusting plates, two rotary shafts, an outer shell and two rotary arms, wherein the air inlet channel is provided with a spacer ring and communicates with the side periphery of the spacer ring, air outlets of the pressure stabilization valve body communicate with the upper end of the spacer ring, the stop valve assembly is arranged at the air inlet channel, the inner shell is connected with the upper end of the pressure stabilization valve body, the two fan-shaped counter bored holes are formed in the upper end of the inner wall, the two inner air outlet channels communicate with the air outlets in a one-to-one correspondence mode, the two fan-shaped adjusting plates are located in the fan-shaped counter bored holes correspondingly, the lower ends of the two rotary shafts are connected with the small ends of the two fan-shaped adjusting plates in a one-to-one correspondence mode, and the outer shell is provided with two outer air outlet channels and is connected with the upper end of the inner shell. The upper ends of the rotary shafts penetrate through the outer shell and are connected with the rotary arms in a one-to-one correspondence mode, and the central angles, corresponding to the axes of the rotary shafts, of the fan-shaped counter bored holes are larger than the central angles, corresponding to the axes of the rotary shafts, of the fan-shaped adjusting plates. According to the double-channel fine adjusting sectioning valve, ventilation can be conducted on the double air outlet channels simultaneously, the air outlets of the double air outlet channels can be adjusted, the stopping function is achieved, and the pressure stabilization effect is good.

Description

technical field [0001] The invention relates to the field of gas devices, in particular to a double-channel fine-adjustment sectional valve. Background technique [0002] The invention of Chinese patent application number CN 201410108245.6 discloses a gas valve with double outlet channels, including a pressure stabilizing valve body, on which an air inlet, a first gas outlet channel and a second gas outlet channel are arranged, and on the pressure stabilizing valve body The body is provided with a valve chamber that communicates with the air inlet and the first air outlet passage, and a rotating valve core is provided in the valve chamber, and a central hole that communicates with the first air outlet passage is provided in the rotating valve core. The wall of the rotary valve core is provided with a main air passage that allows gas to enter the central hole from the air inlet and the air output can be adjusted. and the secondary air passage of the second air outlet passage...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the shortcomings of the current double outlet channel gas valve that the main and auxiliary channels cannot be ventilated at the same time, have no cut-off function, and have poor voltage stabilization effect; therefore, provide a dual outlet channel that can ventilate at the same time and can be adjusted Dual-channel air outlet, double-channel fine-adjustment sectional valve with cut-off function and good pressure stabilization effect
