Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of coal mine gas extraction, especially relates to gas extraction sampling integrated valve. BACKGROUND
[0002] Coal mine gas extraction is a work that needs to be done in the process of coal mining, through gas extraction, not only can reduce the gas emission amount in the process of mining, prevent the occurrence of gas explosion, but also can change harm into benefit, develop and utilize as the associated resources of coal resources.
[0003] The main method is to drill to the coal seam and the area where gas gathers, pull the drill hole to the special pipeline, extract the gas to the ground through the extraction equipment, and utilize or discharge. The gas extraction sampling valve is an important part, the gas in the drill hole can be converged to the main pipeline through the gas extraction sampling valve, and the gas can be sampled.
[0004] And the existing gas extraction sampling valve adopts split assembly to realize gas extraction sampling, the split assembly is mainly assembled by two straight threaded joints, sealing pads, ball valves, one silk and one toothed buckle, and raw material belts, and has many inconveniences in the production and use process. For example, because many spare parts need to be prepared, the procurement cycle is stable, involves many spare part assembly links, and the production efficiency is low. Meanwhile, in the use process, the poor sealing leads to the gas leakage, and safety hazards are caused.
[0005] Therefore, the utility model provides a gas extraction sampling integrated valve. CONTENT OF UTILITY MODEL
[0006] The utility model discloses a gas extraction sampling integrated valve to solve the defects in the prior art.
[0007] In order to realize the above-mentioned purpose, the utility model adopts the following technical scheme:
[0008] The gas extraction sampling integrated valve, including integrated valve body, the integrated valve body includes the valve body, the screw and the toothed buckle of integrated molding, the screw and the toothed buckle are located at the front and back two sides of the valve body respectively, the valve core is rotatably arranged in the valve body, the upper portion of the valve body is equipped with the ball valve handle, and the ball valve handle is connected with the valve core.
[0009] Further, the ball valve handle is in the shape of a straight line or a circle.
[0010] Compared with the prior art, the utility model has the beneficial effects that:
[0011] The utility model discloses a one-piece valve body, a screw thread, a zigzag thread are optimized and integrated into the injection molding form, reduce the spare parts of multiple components, and also do not exist product to the assembly process after the assembly process, and injection molding integral type does not exist sealing washer, raw material belt, avoid the phenomenon of air leakage caused by the situation of bad sealing.
