Problems solved by technology

[0003] However, there are some shortcomings in the flow valves for gas transportation in the market. The traditional flow valve structure is relatively simple, and its flexibility is insufficient. In addition, during use, the self-protection ability is relatively low, and it is easy to cause damage due to excessive pressure impact strength. The flow valve is loose or damaged

Embodiment Construction

[0019] As shown in the attached picture: see Figure 1~3 , in the embodiment of the present invention, a new type of flow valve for gas transportation, including a valve body 1, the two sides of the valve body 1 are symmetrically screwed with a connecting flange 4, and the lower part of the valve body 1 is connected with a The decompression mechanism, the decompression mechanism includes a decompression pipeline 2 connected at the middle position below the valve body 1, the bottom end of the decompression pipeline 2 is connected with an exhaust cylinder 3, and the inner side of the decompression pipeline 2 is engaged with a sealing plug 15 , the inner side of the sealing plug 15 is embedded with a pressure relief channel 16, the sealing plug 15 is made of NBR material, and the pressure relief channel 16 is a T-shaped structure. The matching combination of the pressure passage groove 14 can prevent the flow valve from being loosely connected and blasted due to excessive impact ...

Abstract

The invention relates to the technical field of fuel gas conveying, and discloses a novel flow valve for fuel gas conveying. Connecting flanges are symmetrically screwed to two sides of a valve body,a pressure reducing mechanism is connected to the middle of the lower portion of the valve body, a valve rod is connected with a rotating handle in a clamped mode through a regular hexagonal screw base, a valve ball is fixed to the bottom end of the valve rod, and a circulation groove is formed in the middle of one side of the valve ball in a penetrating mode. According to the novel flow valve, the valve rod is connected with the rotating handle in a clamped mode, under one-to-one correspondence of identification pointers and scale identifications, a worker can conveniently and accurately adjust a flow circulation size of the flow valve, and then the convenience of adjusting and using the flow valve is improved; and in a fuel gas conveying process, through matching and combining of a pressure reducing mechanism and a pressure reducing through groove, the situations that connection of the flow valve is loosened and the flow valve is exploded and damaged due to too large barometric impact strength can be avoided, and then the self-protection capacity of the flow valve is improved.

Description

technical field [0001] The invention relates to the technical field of gas transportation, in particular to a novel flow valve for gas transportation. Background technique [0002] Gas is the general term for gaseous fuel. It can burn and release heat for use by residents and industrial enterprises. There are many types of gas, mainly natural gas, artificial gas, liquefied petroleum gas, biogas, and coal gas. According to the source of natural gas, it can be generally divided into five types: gas field gas (or pure natural gas), petroleum associated gas, condensate gas field gas, coal bed methane and shale gas, which are widely used in household life, In various fields such as industrial manufacturing, in the process of gas transmission and use, the matching combination of pipelines and flow valves is generally used to transport gas. [0003] However, there are some shortcomings in the flow valves for gas transportation in the market. The traditional flow valve structure is...
