Description

Technical Field

[0001] The utility model relates to the technical field of pressure instruments, in particular to a pressure instrument used for fluid measurement. Background Art

[0002] A pressure gauge is an instrument that uses an elastic element as a sensitive element to measure and indicate pressure higher than the ambient pressure. The pressure gauge uses the elastic deformation of the sensitive element inside the gauge, and then the conversion mechanism in the gauge movement transmits the pressure deformation to the pointer, causing the pointer to rotate to display the pressure. Pressure gauges are used in almost all industrial processes and scientific research fields, and can be seen everywhere in thermal pipelines, oil and gas transmission, water and gas supply systems, vehicle repair and maintenance shops, and other fields.

[0003] The pressure gauge in the prior art is often used to detect the pressure of the fluid in the pipeline. However, when the fluid flows in the pipeline, the pressure, velocity, density of the fluid and the pump itself will cause the pipeline to vibrate, which can easily lead to the jitter or instability of the pressure gauge pointer, thereby affecting the accuracy of the measurement. Therefore, we propose a new type of pressure instrument for fluid measurement. Utility Model Content

[0004] The utility model aims to solve the problem in the prior art that when the fluid flows in the pipeline, the pressure, speed, density of the fluid and the pump itself will cause the vibration of the pipeline, which may easily lead to the jitter or instability of the pressure gauge pointer, thereby affecting the accuracy of the measurement, and proposes a pressure meter for fluid measurement.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a pressure instrument for fluid measurement, comprising a first rectangular frame, first dampers are fixedly installed on the top of the first rectangular frame near the four corners, the first dampers are sleeved on the outside with a first shock-absorbing spring, a second rectangular frame is fixedly connected between the tops of multiple first dampers and first shock-absorbing springs, a top plate is provided on the top of the second rectangular frame, connecting blocks are symmetrically fixedly connected to the bottom of the top plate near the edges on both sides, a connecting plate is symmetrically fixedly connected to the bottom of the second rectangular frame, second dampers are symmetrically fixedly installed on the outer surfaces of one side of the two connecting plates, and a second shock-absorbing spring is sleeved on the outside of the second damper.

[0006] Furthermore, one end of each of the second dampers and the second shock absorbing springs is fixedly connected to the outer surface of one side of each of the connection blocks.

[0007] Furthermore, a U-shaped frame is symmetrically fixedly installed on the bottom of the first rectangular frame, and an upper clamping ring is fixedly connected to the bottom of the U-shaped frame.

[0008] Furthermore, the bottom of the upper clamping ring is fixedly connected to the lower clamping ring by bolts, and a pipeline is arranged between the lower clamping ring and the upper clamping ring.

[0009] Furthermore, brackets are symmetrically fixedly connected to the top of the top plate, and locking threaded rods are threadedly penetrated through the outer surfaces of the two brackets.

[0010] Furthermore, one end of the locking threaded rod is fixedly connected with a knob, and the other end of the locking threaded rod is rotatably provided with a clamping plate.

[0011] Furthermore, a pressure gauge is arranged between the two clamping plates, and a pressure-guiding pipe is matched with the outer surface of the pressure gauge. The bottom end of the pressure-guiding pipe is fixedly connected to a metal hose, and the bottom end of the metal hose is connected to the pipeline.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, the first damper and the first shock-absorbing spring cooperate with each other to absorb the vertical vibration force, and the second damper and the second shock-absorbing spring cooperate with each other to absorb the horizontal vibration force, thereby reducing the vertical and horizontal shaking of the pressure gauge. In addition, since the metal hose has a certain flexibility, when the pipeline vibrates, it will not affect the position of the pressure gauge, thereby greatly reducing the shaking or instability of the pressure gauge caused by the pipeline vibration force, thereby improving the measurement accuracy.

[0014] 2. In the utility model, the locking threaded rod is rotated by turning the knob, thereby clamping the pressure gauge between the two clamping plates, thereby fixing the pressure gauge and facilitating the subsequent disassembly and maintenance of the pressure gauge, thereby improving work efficiency.

[0023] The effect achieved by the entire embodiment 1 is that when the pipeline 1 vibrates, the first damper 31 and the first shock-absorbing spring 32 cooperate with each other to absorb the vertical vibration force and reduce the vertical shaking of the pressure gauge 5. The second damper 36 and the second shock-absorbing spring 37 cooperate with each other to absorb the horizontal vibration force and reduce the horizontal shaking of the pressure gauge 5. In addition, since the metal hose 52 has a certain flexibility, the connection relationship between the pressure gauge 5 and the pipeline 1 has a large degree of freedom. When the pipeline 1 vibrates, the position of the pressure gauge 5 is not affected by the metal hose 52. The mutual cooperation has a vibration reduction effect, which can greatly reduce the shaking or instability of the pressure gauge 5 caused by the vibration force of the pipeline 1, thereby improving the measurement accuracy.

[0024] Embodiment 2, as Figure 1-Figure 4 As shown, a U-shaped frame 22 is symmetrically fixedly installed at the bottom of the first rectangular frame 3, an upper clamping ring 21 is fixedly connected to the bottom of the U-shaped frame 22, a lower clamping ring 2 is fixedly connected to the bottom of the upper clamping ring 21 by bolts, a pipe 1 is arranged between the lower clamping ring 2 and the upper clamping ring 21, a bracket 4 is symmetrically fixedly connected to the top of the top plate 34, a locking threaded rod 41 is threadedly penetrated through the outer surfaces of the two brackets 4, a knob 42 is fixedly connected to one end of the locking threaded rod 41, a clamping plate 43 is rotatably arranged at the other end of the locking threaded rod 41, a pressure gauge 5 is arranged between the two clamping plates 43, a pressure gauge 5 is matched with a pressure pipe 51 on the outer surface of the pressure gauge 5, a metal hose 52 is fixedly connected to the bottom end of the pressure pipe 51, and the bottom end of the metal hose 52 is connected to the pipe 1.

[0025] The effect achieved by the entire embodiment 2 is that the lower clamping ring 2 is placed at the bottom of the pipeline 1, the upper clamping ring 21 is placed at the top of the pipeline 1, and then the lower clamping ring 2 and the upper clamping ring 21 are installed on the surface of the pipeline 1 by bolts, and then the pressure gauge 5 is placed between the two clamping plates 43, and the locking threaded rod 41 is rotated by turning the knob 42, so that the pressure gauge 5 is clamped between the two clamping plates 43, which plays a role in fixing the pressure gauge 5 and is convenient for the later disassembly and maintenance of the pressure gauge 5, thereby improving work efficiency. The pressure-conducting pipe 51 at the bottom of the pressure gauge 5 is connected to the pipeline 1 through the metal hose 52, which plays a role in connecting the pressure gauge 5 and the pipeline 1. The overall structure of the device is simple, the installation is convenient and quick, and the practicality is good.

[0026] Working principle: When in use, place the lower clamp ring 2 at the bottom of the pipe 1, and the upper clamp ring 21 at the top of the pipe 1, and then install the lower clamp ring 2 and the upper clamp ring 21 on the surface of the pipe 1 by bolts, and then place the pressure gauge 5 between the two clamping plates 43, and rotate the locking threaded rod 41 by turning the knob 42, so that the pressure gauge 5 is clamped between the two clamping plates 43, which plays a role in fixing the pressure gauge 5, and then connect the pressure pipe 51 at the bottom of the pressure gauge 5 to the pipe 1 through the metal hose 52. When the pipe 1 vibrates, the first damper 31 and the first shock-absorbing spring 32 are mutually matched. The combination can absorb vertical vibration force and reduce the vertical shaking of the pressure gauge 5. The cooperation between the second damper 36 and the second shock-absorbing spring 37 can absorb horizontal vibration force and reduce the horizontal shaking of the pressure gauge 5. Since the metal hose 52 has a certain flexibility, the connection relationship between the pressure gauge 5 and the pipeline 1 has a large degree of freedom. When the pipeline 1 vibrates, the position of the pressure gauge 5 is not affected by the metal hose 52. The cooperation with each other has a vibration reduction effect, which can greatly reduce the shaking or instability of the pressure gauge 5 caused by the vibration force of the pipeline 1, thereby improving the measurement accuracy.
