Valve for compressed gas collecting bottle and concentrating pneumatic control method thereof

Abstract

The invention relates to a valve for compressed gas collecting bottle and a concentrating pneumatic control method thereof. The valve comprises an end cover 1, a connecting sleeve 2, a piston 3, a pressure spring 4, a conical valve core 5, a valve main body 6, a safety screw plug 7, a reset spring 11 and an emergent manual switch component, wherein the reset spring 11, conical valve core 5, the connecting sleeve 2, the pressure spring 4, the piston 3, and the end cover 1 are orderly assembled in the upright cavity of the valve main body 6, from up to down. The safety screw plug 7 of a fusing alloy plug 8 in a side hole is assembled in a left inner hole of the valve main body 6. The emergent manual switch component which comprises a cushion 12, a screw rod 13 and a screw sleeve is assembled in a right inner hole of the valve main body 6 through the screw sleeve 14. The invention can increase the charging / discharging efficiency, relives the labor intensity and is reliable to use. The valve is reasonably designed, the structure is simple and compact, the pneumatic control is utilized, the abrasion is small and the service life is long.

Description

technical field [0001] The invention relates to a special valve for a compressed gas cluster bottle set and a centralized pneumatic control method thereof, in particular to a special valve suitable for filling or unloading natural gas in a compressed natural gas cluster bottle set and a centralized pneumatic control method thereof. Background technique [0002] With the rapid popularization of the use of natural gas, natural gas has become one of the main green and clean energy sources in my country. In the background technology, long-tube trailers are commonly used in the domestic transportation of compressed natural gas, but the long-tube trailers have gradually failed due to their limitations such as excessive length and weight, low gas carrying capacity, high manufacturing costs, and inconvenient assembly and disassembly inspections. Adapt to the complex and changeable use and transportation environment of various industries. At present, storage containers for storing a...

AI Technical Summary

Problems solved by technology

Due to the large number of gas cylinders in the gas cylinder cluster group, there are many gas intake nodes in the entire cluster group of cylinders. Air release, the work efficiency is extremely low, and it is not convenient to realize remote and centralized control. At the same time, when the solenoid valve changes direction, the system needs to be equipped with an explosion-proof device, which greatly increases the cost and is difficult to guarantee safety.
