Embodiment

[0014] Such as figure 1 , 2 As shown, a track-type natural gas pipeline valve includes a valve seat 1, a top beam 2 is installed above the valve seat 1, and a suspended guide rail 3 is installed below the top beam 2, and the guide rails 3 are sequentially below A valve plate 7 and a frame 4 are fixed; a valve ring 5 is installed in the middle of the frame 4 .

[0015] In order to keep the guide rail 3 moving during the movement and make it difficult to desolder, a fixed arm 6 is installed at the joint between the valve seat 1 and the guide rail 3 .

[0016] when working, such as Figure 1-2 As shown, the guide rail drives the valve plate and frame 4 to slide from left to right. First, the valve plate 7 leaves the valve seat 1 and continues to move forward, and then the valve ring 5 enters the valve seat 1, which realizes the process from closing to opening of the valve. The surface of the valve ring 5 is provided with a circle of rubber pads, which can effectively prevent n...

Abstract

The invention discloses a track-type natural gas pipeline valve, which comprises a valve seat, wherein a top beam is mounted above the valve seat; an impending guide track is mounted below the top beam; a valve plate and a frame is fixed below the guide track in sequence; a valve ring is mounted at the middle of the frame. The valve has fast on / off speed, small occupied space, and convenience in operation. According to the valve, the guide track drives the valve plate and the valve ring to move to realize the on / off of the valve, so as to be time-saving and labor-saving, convenient to operate, and high in stability coefficient.

Description

technical field [0001] The invention relates to the technical field of valve manufacturing, in particular to an orbital natural gas pipeline valve. Background technique [0002] The sealing requirements of urban natural gas pipelines are relatively high. Once a leak occurs, it will not only pollute the environment, but more seriously, it will easily lead to house fire or explosion. Therefore, the closed and opened valves have higher requirements for sealing, stability and corrosion resistance. [0003] For some large natural gas pipelines, the opening and closing of the valves cannot be controlled manually, and the valves need to be controlled by means of power equipment. Due to the large diameter of the pipeline, the power and space required for its opening and closing are large, and the operation is not very convenient. In addition, the power equipment for controlling the valve leads to a large overall occupation area and high safety risks. Contents of the invention ...
