Description

Technical Field

[0001] The present application relates to the technical field of natural gas compressors, and in particular to a natural gas compressor equipped with an emergency pressure-changing valve. Background Art

[0002] A natural gas compressor is a device specially used to compress natural gas to increase its pressure. With the rapid development of the oil and gas industry, natural gas compressors are being used more and more widely, and have been popularized and developed in oil field exploitation, long-distance pipelines, and urban natural gas distribution systems. In natural gas long-distance pipelines and urban gas distribution systems, natural gas compressors are used to compress natural gas to the required pressure to ensure the stable transportation of natural gas. During the transportation of natural gas, related transmission pipelines may leak, and the leaked natural gas may continue to flow to downstream equipment or pipelines, causing the scope of the accident to expand. The emergency pressure transformer can quickly reduce the natural gas pressure in an emergency to prevent the accident from further deteriorating. In the early stage, the emergency pressure transformer of the natural gas compressor is generally directly exposed to the outside world. When it is hit, the valve handle may move, thereby causing the natural gas pressure to change, affecting the transportation efficiency. The pressure transformer is connected to the main pipeline. Once damaged, it will affect normal transportation. Therefore, a new technical solution needs to be designed to solve it. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of this application are as follows:

[0012] 1. The present application can prevent collision and accidental touch through the constraint plate, arc groove, slider, connecting block and valve stem. After the transformer valve body is clamped, the valve stem and the slider in the arc groove are connected together through the connecting block. At this time, the valve stem will be restricted from moving. When it needs to be moved, the extrusion bolt on the surface of the slider must be loosened and then tightened after adjusting the pressure, thereby ensuring the stability and safety of the transformer valve body and improving the practicality of the device.

[0013] 2. The present application can facilitate the disassembly and assembly of the transformer valve body through the electric push rod, telescopic rod and lifting block.

When one of the pressure-transforming valve bodies needs to be repaired and disassembled, it is only necessary to close the valve of the corresponding delivery pipeline to allow the other pressure-transforming valve body to work normally, thereby ensuring the normal delivery and maintaining the stability of the equipment.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects of the utility model easier to understand, they are further explained below in conjunction with specific implementation methods.

[0022] A natural gas compressor equipped with an emergency pressure changing valve, see Figures 1 to 4 , including a protection box 1, a transformer valve body 2, a compressor body 15 and a constraint plate 5, the left and right inner walls of the protection box 1 are each provided with two upper and lower parallel adjustment grooves 9, the inner side of the adjustment groove 9 is rotatably connected with a two-way screw rod 11, the surface of the two-way screw rod 11 is threadedly connected with thread blocks 10 on both sides, the outer wall of the thread block 10 is fixedly connected with a clamping block 12, the clamping block 12 clamps the transformer valve body 2 from both sides under the drive of the two-way screw rod 11, thereby ensuring stability; an electric push rod 3 is fixedly connected to the bottom center of the protection box 1, the top of the electric push rod 3 is fixedly connected with a support block 4, the top of the support block 4 is fixedly connected with a constraint plate 5, and the left and right sides of the top of the constraint plate 5 are each provided with an arc groove 6, the surface of the arc groove 6 is slidably connected with a slider 7, and the bottom part of the slider 7 located in the arc groove 6 is cylindrical, thereby ensuring that the protection box 1 does not move during movement. It will get stuck, the valve stem 201 at the top of the transformer valve body 2 is located on the surface of the constraint plate 5 on one side of the arc groove 6, and the slider 7 is fixedly connected with a connecting block 8 on the side wall facing the valve stem 201. The connecting block 8 and the top of the valve stem 201 are detachably connected by a connecting bolt 801, and the valve stem 201 and the slider 7 in the arc groove 6 are connected together by the connecting block 8. At this time, the valve stem 201 will be restricted from moving, thereby maintaining stability; the left and right side walls of the support block 4 are fixedly connected with a telescopic rod 13, and the other end of the telescopic rod 13 is fixedly connected with a lifting block 14. After starting, the electric push rod 3 can drive the lifting block 14 and the transformer valve body 2 to lift together, which facilitates the disassembly of the transformer valve body 2. The interfaces at both ends of the transformer valve body 2 are fixedly connected and communicated with the delivery pipeline 16, which can ensure that natural gas can be normally delivered when one of the transformer valve bodies 2 is damaged.

[0023] Specifically, Figure 2 As shown, one end of the bidirectional screw rod 11 passes through the side wall of the protection box 1 and is fixedly connected to the twist block 111. The twist block 111 is located outside the protection box 1. The twist block 111 can be rotated manually, thereby driving the bidirectional screw rod 11 to rotate and clamping the transformer valve body 2.

[0024] It is worth noting that the interfaces at both ends of the pressure-changing valve body 2 are fixedly connected and communicated with the delivery pipeline 16, and the compressor body 15 and the pressure-changing valve body 2 are fixedly connected and communicated through the delivery pipeline 16. The delivery pipeline 16 is branched, and each branch is provided with a separate valve for closing the channel when the pressure-changing valve body 2 of the current passage is disassembled, so that natural gas can be delivered from another channel.

[0025] It is worth noting that if Figure 4 As shown, the top end of the slider 7 is threadedly connected with a squeezing bolt 701 . After being tightened, the squeezing bolt 701 will squeeze the slider 7 tightly against the surface of the arc groove 6 , thereby constraining and fixing the valve stem 201 .

[0026] It is worth noting that if Figure 2 As shown, a buffer pad 17 is fixedly connected to the bottom of the protection box 1 directly below the transformer body 2. The buffer pad 17 can buffer the bottom of the transformer body 2 when the electric push rod 3 descends with the transformer body 2 to avoid damage caused by strong impact.

[0028] In actual use, the pressure-changing valve body 2 is placed on both sides of the protection box 1, and the twist block 111 is rotated to drive the two-way screw rod 11 to rotate, so that the threaded block 10 moves with the clamping block 12 toward the pressure-changing valve body 2, and finally the pressure-changing valve body 2 is clamped. After the pressure-changing valve body 2 is clamped, the valve stem 201 and the slider 7 in the arc groove 6 are connected together through the connecting block 8. At this time, the valve stem 201 will be restricted from moving. When it needs to move, the extrusion bolt 701 on the surface of the slider 7 must be loosened, and it can be tightened after the pressure is adjusted, thereby ensuring the stability and safety of the pressure-changing valve body 2 and improving the device. The practicality of the device is that when disassembling the pressure regulating valve body, the length of the telescopic rod 13 is adjusted to allow the lifting blocks 14 to be inserted into the two sides of the transformer body 2, and then the electric push rod 3 can drive the lifting blocks 14 and the transformer body 2 to lift together after starting, which facilitates the disassembly of the transformer body 2 and improves the convenience and practicality of the device. Two transformer bodies 2 are arranged in the protective box 1, and the two are connected by a branched conveying pipe 16. When one of the transformer bodies 2 needs to be repaired and disassembled, it is only necessary to close the valve of the corresponding conveying pipe 16 to allow the other transformer body 2 to work normally.
