Description

Technical Field

[0001] This utility model relates to the field of differential pressure gauges, and more specifically, to a high static differential pressure gauge that is easy to assemble. Background Technology

[0002] The main function of a high static pressure differential gauge is to measure the static pressure difference between two different locations. It can accurately measure the static pressure difference of gas or liquid in pipelines, containers, storage tanks, etc. In differential pressure measurement in petrochemical, power and other enterprises, it is mainly used for differential pressure measurement of centrifuges, compressor lubrication systems and filters, etc. The displacement is transmitted to the indicating system, which is usually a pointer and a dial, for visually displaying the pressure difference value.

[0003] However, most high static pressure differential pressure gauges currently have the following problems:

[0004] For example, a novel high static pressure differential pressure gauge with publication number 201820953968.X, although it can be connected and used through an installed connector, can easily cause blockage of the differential pressure gauge when liquids or gases enter the gauge through pipelines, due to impurities and dust, affecting the measurement accuracy and service life of the differential pressure gauge, and making it inconvenient to filter and collect impurities in the transported liquids or gases; at the same time, existing high static pressure differential pressure gauges are difficult to install on pipelines of different sizes during installation, causing the dial to tilt and affecting subsequent readings, making it inconvenient to assemble and use the gauge.

[0005] Therefore, we have made improvements to this and proposed a high static differential pressure gauge that is easy to assemble. Utility Model Content

[0006] The purpose of this utility model is to address the current problems of inconvenience in filtering and collecting impurities in transported liquids or gases, and the inconvenience in assembling and using the instrument body.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A high static pressure differential pressure gauge that is easy to assemble can improve the above problems.

[0009] The application is as follows:

[0010] The device includes a dial indicator and a connecting pipe. The connecting pipe is mounted on the dial indicator, and a processing box is fixedly connected to the connecting pipe. A cover plate is provided on the processing box, and a sealing gasket and a filter screen are fixedly connected to the cover plate. A positioning plate is fixedly connected to the connecting pipe, and a rotating rod is rotatably connected to the cover plate. A first bevel gear is fixedly connected to the rotating rod, and a second bevel gear meshes with the first bevel gear. A threaded rod is fixedly connected to the second bevel gear, and the threaded rod is rotatably connected to the cover plate. A moving plate is threadedly connected to the threaded rod, and a pressing box is fixedly connected to the moving plate. An assembly box is fixedly connected to the dial indicator, and a rotating shaft is rotatably connected to the assembly box. A material roller is fixedly connected to the rotating shaft, and a rope is fixedly connected to the material roller. The other end of the rope is bolted to the dial indicator. A turntable is fixedly connected to the rotating shaft, and a spring is fixedly connected inside the turntable. A limit plate is fixedly connected to the other end of the spring, and a locking block is fixedly connected to the limit plate.

[0011] As a preferred technical solution of this application, the side end face of the filter screen is fitted with the inner side of the processing box, and the positioning plate is provided with an inclined through hole.

[0012] As a preferred technical solution of this application, the threaded rods are symmetrically distributed on the upper and lower sides inside the cover plate, and the threaded rods correspond one-to-one with the extrusion box through the moving plate.

[0014] As a preferred technical solution of this application, the springs are symmetrically distributed on the upper and lower sides of the turntable, and the springs correspond one-to-one with the locking blocks through the limiting plates.

[0015] As a preferred technical solution of this application, an extrusion plate is fixedly connected to the limiting plate, and a positioning frame is fixedly connected to the assembly box, with slots opened at equal angles in the positioning frame.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] In the scheme of this application:

[0018] 1. Equipped with a processing box; when the connecting pipe is transporting liquid or gas, it passes through the processing box and can filter and collect residual impurities through the internally installed filter screen to prevent impurities from affecting the adaptability of the surface. When the filter screen needs to be cleaned, the rotating rod can be rotated to drive the first bevel gear to rotate. The first bevel gear can drive the threaded rod to rotate through the second bevel gear. The threaded rod drives the extrusion box to move inward through the moving plate, disengaging the extrusion box from the positioning plate. After it is unobstructed, the cover plate and the connected filter screen can be removed for subsequent cleaning and use.

[0019] 2. Equipped with a rope strap; when assembling the meter body onto a pipe, the pipe can be passed through the rope strap, or the bolts on the rope strap can be removed, and the rope strap can be tied to the pipe and fixed to the meter body with bolts. When winding the rope strap, the squeezing plates on both sides of the turntable can be squeezed to move the limiting plate. While the limiting plate squeezes the spring, it can also drive the locking block to disengage from the positioning frame and retract into the turntable. After being unobstructed, the turntable can be rotated to drive the material roller on the rotating shaft to rotate. The material roller can wind up the rope strap to tighten the assembled meter body. When the squeezing plate is released, the limiting plate and locking block are reset under the push of the spring. The locking block is engaged in the positioning frame, which can play a role in positioning and fixing, improving the assembly stability. Attached Figure Description

A spring 19 is fixedly connected to the turntable 18 and is fixedly connected to the other end of the spring 19. A limit plate 20 is fixedly connected to the limit plate 20 and is fixedly connected to the limit plate 20. A locking block 21 is fixedly connected to the limit plate 20.

[0035] Example 2:

[0036] The solution in Example 1 will be further described below with reference to its specific working method.

[0037] like Figure 5 As shown, in a preferred embodiment, based on the above method, the side end face of the filter screen 6 is fitted with the inner side of the treatment box 3, and the positioning plate 7 is provided with an inclined through hole, which can ensure that the liquid passing through the treatment box 3 can be fully filtered and treated by the filter screen 6.

[0038] like Figure 3 As shown, in a preferred embodiment, based on the above method, the threaded rods 11 are symmetrically distributed on the upper and lower sides of the cover plate 4. The threaded rods 11 correspond one-to-one with the extrusion boxes 13 through the moving plate 12, which can ensure that the extrusion boxes 13 on both sides can be engaged in the positioning plate 7 to fix and connect the cover plate 4.

[0039] like Figure 4 As shown, in a preferred embodiment, based on the above method, the side end face of the movable plate 12 is in contact with the inner side face of the cover plate 4, and the end of the extrusion box 13 is inclined, which can ensure that the inclined surface of the extrusion box 13 can press the inclined surface of the positioning plate 7 to fix the cover plate 4.

[0040] like Figure 6As shown, in a preferred embodiment, based on the above method, the springs 19 are symmetrically distributed on the upper and lower sides of the turntable 18. The springs 19 correspond one-to-one with the locking blocks 21 through the limiting plate 20, which can ensure that the locking blocks 21 on both sides can be locked in the positioning frame 23 to position the turntable 18.

[0041] like Figure 6 As shown, in a preferred embodiment, based on the above method, a compression plate 22 is fixedly connected to the limiting plate 20, and a positioning frame 23 is fixedly connected to the assembly box 14. The positioning frame 23 has slots opened at equal angles, which can ensure that the slots opened at equal angles can engage the limiting turntable 18.

[0042] Specifically, this easy-to-assemble high static pressure differential pressure gauge should be used in conjunction with: Figure 1-7 When the connecting pipe 2 is transporting liquid or gas, it passes through the processing box 3 and can filter and collect residual impurities through the internally installed filter screen 6 to prevent impurities from affecting the adaptability of the body 1. When the filter screen 6 needs to be cleaned, the rotating rod 8 can be rotated to drive the first bevel gear 9 to rotate. The first bevel gear 9 can drive the threaded rod 11 to rotate through the second bevel gear 10. The threaded rod 11 drives the squeezing box 13 to move inward through the moving plate 12, disengaging the squeezing box 13 from the positioning plate 7. After it is unobstructed, the cover plate 4 and the connected filter screen 6 can be removed for subsequent cleaning. When reinstalling, the threaded rod 11 can be rotated in the opposite direction. The threaded rod 11 drives the squeezing box 13 to move outward through the moving plate 12. The squeezing box 13 can be engaged in the positioning plate 7, positioning the cover plate 4. When the squeezing box 13 continues to move, the inclined surface can squeeze and fix the cover plate 4. The sealing gasket 5 on the cover plate 4 can squeeze and seal on the processing box 3, improving the sealing and protection effect.

[0043] When assembling the gauge body 1 onto the pipeline, the pipeline can be passed through the rope 17, or the bolts on the rope 17 can be removed, and the rope 17 can be tied to the pipeline and fixed to the gauge body 1 with bolts. When winding the rope 17, the squeezing plates 22 on both sides of the turntable 18 can be squeezed to drive the limiting plate 20 to move. While the limiting plate 20 squeezes the spring 19, it can drive the locking block 21 to disengage from the positioning frame 23 and return to the turntable 18. After being unobstructed, the turntable 18 can be rotated to drive the material roller 16 on the rotating shaft 15 to rotate in the assembly box 14. The material roller 16 can wind up the rope 17 to tighten the assembly gauge body 1. When the squeezing plate 22 is released, the limiting plate 20 and the locking block 21 are reset under the push of the spring 19. The locking block 21 is engaged in the positioning frame 23, which can play a positioning and fixing role and improve the assembly stability. The gauge body 1 used is model (SY04-YCA high static pressure differential pressure gauge).
