[0002] Natural gas is a natural gas mixture mainly composed of methane, usually found in underground rock formations. It is a clean fossil fuel often used for power generation, heating and cooking. The main component of natural gas is methane, but it also includes small amounts of ethane, propane, butane and other gases.

[0003] When natural gas is being transported, in order to meet usage needs, the natural gas content needs to be tested regularly. However, it is not convenient to test natural gas during transportation, so valves need to be installed. However, most of the existing valves use normal valves. Therefore, when testing the natural gas content, it is necessary to connect the detection tube of the detection equipment to the natural gas valve and then open the valve. After the test, the valve needs to be closed and the detection tube of the detection equipment needs to be removed. When the staff forgets to close the valve and directly removes the detection tube, it will cause safety hazards and is inconvenient to use. Utility Model Content

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1 , Figure 2 , Figure 3 The utility model provides a technical solution: a valve for conveniently detecting the content of natural gas, comprising a valve body 1, a fixed sleeve 2 is fixedly connected to the output end of the valve body 1, a fixed block 3 is fixedly connected to the inner wall of the fixed sleeve 2 near the center of the valve body 1, a T-shaped limit rod 4 is slidably connected inside the fixed block 3, a connecting plate 5 is fixedly connected to the end of the T-shaped limit rod 4 away from the center of the valve body 1, a rubber pad 6 is fixedly connected to the side of the connecting plate 5 away from the T-shaped limit rod 4, a first tension spring 7 is fixedly connected to the side where the fixed block 3 and the connecting plate 5 are close to each other, a first push rod 8 is fixedly connected to the side where the connecting plate 5 is away from the T-shaped limit rod 4, and the fixed sleeve 2 is away from the center of the valve body 1. One end of the valve body 1 is fixedly connected to a fixing ring 11, the outer ring of the fixing ring 11 is inlaid with a sealing ring 12, the outer wall of the fixing cylinder 2 is slidably connected to a sliding box 9, the outer wall of the sealing ring 12 slides in a sealing manner with the inner wall of the sliding box 9, the outer wall of the sliding box 9 is fixedly sleeved with a rubber sleeve 10, the side of the sliding box 9 away from the inner wall of the fixing cylinder 2 is fixedly connected to a fixing frame 15, the side of the fixing frame 15 close to the inside of the sliding box 9 is fixedly connected to a second push rod 16, the outer wall of the fixing cylinder 2 is fixedly sleeved with a fixing sleeve plate 14, the outer wall of the fixing cylinder 2 is sleeved with a second tension spring 13, and both ends of the second tension spring 13 are fixedly connected to the fixed sleeve plate 14 and the side of the sliding box 9 close to each other.

[0019] By putting the valve body 1 in a normally open state, the detection tube of the detection equipment is sleeved on the outer wall of the rubber sleeve 10 and pushes the rubber sleeve 10, thereby effectively realizing that the natural gas can enter the interior of the sliding box 9, thereby facilitating the detection of the natural gas content. When detection is not needed, by loosening the pipeline that pushes the rubber sleeve 10, the problem of natural gas leakage can be avoided under the tension of the first tension spring 7 and the second tension spring 13, and it is also convenient when the natural gas content needs to be detected, and the safety can also be increased by the valve body 1.

[0020] The fixed tube 2 is funnel-shaped, the four corners of the fixed block 3 are fixedly connected to the inner wall of the fixed tube 2, there are four T-shaped limit rods 4, and they are arranged in a circular equidistant array around the center point of the fixed tube 2, the cross-section of the rubber sleeve 10 is an equilateral trapezoid, and the fixing frame 15 is in the shape of a "cross".

[0021] Working principle: First, connect the end of the valve body 1 away from the fixed tube 2 to the natural gas pipeline. Normally, the valve body 1 is in an open state. When the natural gas content needs to be measured, the detection tube of the detection equipment is sleeved on the outer wall of the rubber sleeve 10. Since the cross-section of the rubber sleeve 10 is an equilateral trapezoid, it is convenient to better sleeve the detection tube of the detection device on the outer wall of the rubber sleeve 10. After the sleeve connection, the detection tube is pushed, so the detection tube will give a thrust to the rubber sleeve 10. After the rubber sleeve 10 is pushed, it will drive the sliding box 9 to push, and then drive the fixed frame 15 and the second push rod 1 6 approaches one side of the fixed cylinder 2, and the first push rod 8 can be pushed by the second push rod 16. After the first push rod 8 is pushed, the first push rod 8 will push the connecting plate 5, so that the connecting plate 5 will drive the rubber pad 6 to move to one side of the valve body 1, thereby facilitating the gas inside the natural gas pipeline to enter the interior of the fixed cylinder 2 from the valve body 1, and thus enter the interior of the sliding box 9, thereby facilitating the detection equipment to detect the natural gas content. When the sliding box 9 slides on the outer wall of the fixed cylinder 2, because the end of the fixed cylinder 2 away from the valve body 1 is fixedly connected with the fixing ring 11, and the outer ring of the fixing ring 11 A sealing ring 12 is embedded inside, and the sealing ring 12 slides in a sealed manner with the inner wall of the sliding box 9, thereby effectively preventing the natural gas entering the sliding box 9 from leaking out from between the sliding box 9 and the outer wall of the fixed tube 2. After detecting the content, the detection tube of the detection equipment is taken out from the outside of the rubber sleeve 10. Because the inner wall of the fixed tube 2 is fixedly connected with a fixed block 3, and the fixed block 3 can support the four T-shaped limit rods 4, and at the same time, the first tension spring 7 will squeeze the connecting plate 5 under the action of tension, thereby making the rubber pad 6 fit with the inner wall of the fixed tube 2, thereby preventing the natural gas from leaking out. A fixed sleeve 14 is fixedly sleeved on the outer wall of the fixed cylinder 2, and the second tension spring 13 can be supported by the fixed sleeve 14. The second tension spring 13 will push the sliding box 9 under the action of tension, so the sliding box 9 will move to the side away from the fixed cylinder 2, thereby avoiding the second push rod 16 from not contacting and being away from the first push rod 8, thereby making it easier for the detection tube of the next detection equipment to be sleeved on the outer wall of the rubber sleeve 10, and also avoiding the second push rod 16 pushing the first push rod 8 to cause the rubber pad 6 to be away from the inner wall of the fixed cylinder 2 and cause natural gas leakage when the detection tube of the detection equipment is sleeved.

[0022] The above-mentioned specific embodiments are only several preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
