It is a high-quality fuel and chemical raw material, so in the process of natural gas transportation, corresponding metering valves will be used to monitor it, and in order to increase the service life of the metering valve, it is necessary to clean the metering valve regularly, so the corresponding cleaning device will be used, but it still has the following disadvantages in actual use:

[0003] 1. When the existing cleaning device is used, after the metering valve is installed, there will be a dead angle in the surrounding environment. Since the cleaning device cannot be controlled to align with the position of the metering valve in the dead angle, the surface of the metering valve cannot be fully cleaned;

[0004] 2. When the existing cleaning device is in use, the nozzle used in the cleaning device does not have the function of adjusting the length. Therefore, after the nozzle head moves, the length of the nozzle will increase. When the nozzle head retracts, the nozzle will not be able to automatically reset, causing the nozzle to become too loose and have the problem of shaking at will. Utility Model Content

[0005] The utility model aims to provide a natural gas metering valve cleaning device, which drives the movement of the nozzle along the T-shaped arc mouth by an I-shaped arc block and uses a corrugated hose, thereby solving the problems of being unable to perform comprehensive cleaning work on the surface of the metering valve and causing the nozzle to be too loose and shake randomly.

[0006] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0007] The utility model discloses a natural gas metering valve cleaning device, comprising a connecting plate, a semicircular plate is fixed on the right end of the connecting plate, a T-shaped arc opening is penetrated through the upper surface of the semicircular plate, an I-shaped arc block used in conjunction with the T-shaped arc opening is slidably arranged inside the T-shaped arc block, a nozzle is fixed in the middle of the I-shaped arc block, a connecting pipe is fixed on the side wall around the nozzle located above the I-shaped arc block, a cleaning cylinder is arranged on the left side of the connecting plate, a pump body connected to the inside of the cleaning cylinder is fixed on the upper end of the cleaning cylinder, and a corrugated hose connected to the pump body is fixed on the left end of the connecting pipe.

[0008] Furthermore, a positioning plate is fixed on the upper surface of the connecting plate near the semicircular plate, a positioning hole is penetrated through the side of the positioning plate, the connecting pipe slides through the inner position of the positioning hole, and the corrugated hose is located to the left of the positioning hole.

[0009] Furthermore, a vertical plate is fixed to the left end of the lower surface of the connecting plate, and a placement plate connected to the lower end surface of the cleaning cylinder is fixed to the lower portion of the left side of the vertical plate.

[0010] Furthermore, the front and rear parts of the cleaning cylinder are fitted with limit frames, and the front and rear parts of the right side of the vertical plate are provided with turning openings at positions at the same height as the limit frames.

[0011] Furthermore, a rotating rod is fixed between the upper and lower end surfaces of the rotating port, and the right end of the limiting frame is tightly rotatably sleeved on the peripheral side of the rotating rod through the sleeve hole opened through it.

[0012] Furthermore, a rubber clip strip which is sleeved on the circumference of the cleaning cylinder is fixed to the left end of the connecting plate.

[0013] The utility model has the following beneficial effects:

[0014] 1. When the utility model is in use, the semicircular plate is arranged above the metering valve, and the pump body is controlled to work at this time, so that the pump body will spray the cleaning liquid inside the cleaning cylinder from the position of the connecting pipe and the nozzle, and clean the surface of the metering valve. At the same time, when it is necessary to clean the front and back positions of the cleaning cylinder, the I-shaped arc block can be controlled to slide inside the T-shaped arc mouth, and the I-shaped arc block will drive the nozzle to move to the front and back of the metering valve, so that the nozzle can clean the front and back positions of the metering valve, and the metering valve can be fully cleaned.

[0015] 2. When the utility model is in use, after the nozzle is driven to slide by the I-shaped arc block, the nozzle will pull the connecting pipe, thereby the connecting pipe will pull the corrugated hose, thereby making the length between the connecting pipe and the corrugated hose longer, thereby facilitating the movement of the nozzle. At the same time, after the nozzle moves in the direction of the connecting pipe, the corrugated hose will automatically reset, thereby preventing the connecting pipe from being too loose and causing the connecting pipe to shake at will.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] See also Figure 1-4 As shown, the utility model is a natural gas metering valve cleaning device, comprising a connecting plate 1, a semicircular plate 3 is fixed to the right end of the connecting plate 1, a T-shaped arc opening 301 is penetrated through the upper surface of the semicircular plate 3, an I-shaped arc block 201 used in conjunction with the T-shaped arc opening 301 is slidably arranged inside the T-shaped arc opening 301, a nozzle 2 is fixed in the middle of the I-shaped arc block 201, and the nozzle 2 is driven by the I-shaped arc block 201 to slide inside the T-shaped arc opening 301, thereby enabling the nozzle 2 to move to the rear position of the metering valve, so as to clean the rear of the metering valve. For cleaning work at the position, a connecting pipe 6 is fixed to the side wall of the nozzle 2 above the I-shaped arc block 201, and a cleaning cylinder 5 is arranged on the left side of the connecting plate 1. A pump body 501 connected to the inside of the cleaning cylinder 5 is fixed to the upper end of the cleaning cylinder 5, and a corrugated hose 601 connected to the pump body 501 is fixed to the left end of the connecting pipe 6. After the corrugated hose 601 is set and used, the length between the connecting pipe 6 and the corrugated hose 601 can be adjusted at will, so that the nozzle 2 can slide along the position of the T-shaped arc opening 301.

[0025] Among them Figure 1 , 2As shown in FIG. 3 , a positioning plate 101 is fixed at a position on the upper surface of the connecting plate 1 near the semicircular plate 3, and a positioning hole 102 is formed through the side of the positioning plate 101. The connecting pipe 6 slides through the inner position of the positioning hole 102, and the corrugated hose 601 is located on the left side of the positioning hole 102. When the nozzle 2 pulls the corrugated hose 601 through the connecting pipe 6, the corrugated hose 601 can pass through the positioning hole 102, so that the positioning hole 102 will limit the corrugated hose 601, thereby reducing the corrugated hose 601. The pulling force of the corrugated hose 601 on the I-shaped arc block 201 ensures that the nozzle 2 will not be pulled back again after the position is adjusted. A vertical plate 104 is fixed to the left end of the lower surface of the connecting plate 1, and a placement plate 107 connected to the lower end surface of the cleaning cylinder 5 is fixed to the lower part of the left side of the vertical plate 104. A rubber clip 103 that is sleeved on the peripheral side of the cleaning cylinder 5 is fixed to the left end of the connecting plate 1. The rubber clip 103 is sleeved on the peripheral side of the cleaning cylinder 5, and then the rubber clip 103 performs preliminary positioning of the cleaning cylinder 5.

[0026] Among them Figure 1 , 2 As shown in Figure 4, the front and rear parts of the cleaning cylinder 5 are fitted with the limit frame 4, and the front and rear parts of the right side of the vertical plate 104 are provided with a turning opening 105 at the same height as the limit frame 4. A turning rod 106 is fixed between the upper and lower end surfaces of the turning opening 105, and the right end portion of the limit frame 4 is tightly rotatably sleeved on the circumferential side of the turning rod 106 through the sleeve hole 401 opened therethrough. After the control limit frame 4 rotates, the limit frame 4 will rotate on the circumferential side of the turning rod 106 through the sleeve hole 401, and the limit frame 4 will rotate and move inside the turning opening 105.

[0027] A specific application of this embodiment is: through the use of the above-mentioned structure, when the metering valve needs to be cleaned, the semicircular plate 3 is set at the upper position of the metering valve, and the pump body 501 is controlled to work, so that the pump body 501 will spray the cleaning liquid inside the cleaning cylinder 5 from the position of the connecting pipe 6 and the nozzle 2, and clean the surface of the metering valve. At the same time, when it is necessary to clean the front and back positions of the cleaning cylinder 5, the I-shaped arc block 201 can be controlled to slide inside the T-shaped arc opening 301, and the I-shaped arc block 201 will drive the nozzle 2 to move to the front and back of the metering valve, so as to The nozzle 2 can clean the front and rear positions of the metering valve. At the same time, after the nozzle head 2 is driven to slide by the I-shaped arc block 201, the nozzle head 2 will pull the connecting pipe 6, thereby the connecting pipe 6 will pull the corrugated hose 601, and then the length between the connecting pipe 6 and the corrugated hose 601 can be lengthened, thereby facilitating the movement of the nozzle head 2. At the same time, after the cleaning cylinder 5 is set on the placement plate 107, the cleaning cylinder 5 will be initially limited by the rubber clip 103, so the limiting frame 4 can be rotated to make the end of the limiting frame 4 abut against the peripheral side of the cleaning cylinder 5, thereby ensuring the stable position of the limiting frame 4.
