Description

Technical Field

[0001] The utility model relates to the technical field of mine filling pipeline pressure monitoring, in particular to a filling pipeline pressure monitoring component. Background Art

[0002] In the mine filling industry, pipeline pressure is an important technical indicator parameter and has a very important reference value for filling safety measures.

[0003] The data from pipeline pressure monitoring can indirectly reflect the carrying capacity of the filling pipeline. If the pressure is too high, there may be risks of pipe blockage and equipment failure; if the pressure is too low, there may be insufficient pipes upstream. The operating parameters of the filling system can be adjusted in time according to the pressure parameters to maximize the pipeline transportation capacity and improve work efficiency.

[0004] At present, conventional pipeline pressure monitoring mostly uses diaphragm pressure gauges, but there are errors in the detection of paste-like conveying fluids; and for tailings filling pipelines, due to the small size of the diaphragm or sensor and the sudden change in the diameter of the connecting pipe, the neck of the connecting pipe often becomes hardened, which in turn affects the use of the sensor and normal production operations.

[0005] To this end, the present application designs a filling pipeline pressure monitoring component to solve the above-mentioned problems. Utility Model Content

[0006] In order to make up for the deficiencies in the prior art, the utility model provides a filling pipeline pressure monitoring component.

[0007] The utility model is realized through the following technical solutions:

[0008] A filling pipeline pressure monitoring component is characterized in that an oil pressure gauge is installed on the top of a pressure measuring cylinder, and a hand pressure pump, an exhaust needle valve, a pressure sensor reserved interface, and a safety valve are installed on the four sides of the pressure measuring cylinder.

[0009] An oil distributor is installed between the hand pump and the pressure measuring cylinder, and a one-way valve is installed above the oil distributor. The hand pump mainly plays the role of initial pressure replenishment and fluid replenishment for the pressure measuring cylinder.

[0010] The reserved interface of the pressure sensor can be connected to the electronic pressure sensor, which can remotely monitor the pressure data and realize the transmission of pipeline pressure data, facilitating automated integrated control.

[0011] The bottom end of the pressure measuring cylinder is a mounting flange, and the high-elastic rubber is installed on the flange end. The high-elastic rubber is fixed to the bottom of the pressure measuring cylinder through a gland. At the same time, an O-ring is provided on the gland to effectively prevent oil and liquid leakage.

[0012] The pressure monitoring component can be connected to the pipeline to be measured through the flange of the pressure measuring cylinder. The high-elastic rubber in the pressure measuring cylinder is in contact with the fluid in the pipeline. The high-elastic rubber is pressurized when the fluid flows through it, and the pipeline pressure is displayed by the pressure gauge installed on the top of the pressure measuring cylinder.

[0013] The hand pump mainly plays the role of initial pressure replenishment and fluid replenishment for the pressure measuring cylinder; the needle valve can adjust the initial pressure and exhaust the air mixed in the cylinder to ensure the accuracy of the monitoring data; the safety valve can ensure the initial pressure of the pressure measuring cylinder and prevent the pressure measuring cylinder from overloading due to equipment failure.

[0014] The beneficial effects of the utility model are:

[0015] The filling pipeline pressure monitoring component uses the pressure impact of the fluid on the high-elastic film, and adds a hand pump and a one-way valve, an exhaust needle valve, an oil pressure gauge and other components on the basis of the pressure measuring cylinder. It can display the pipeline pressure changes in real time, and the component maintenance method is more convenient and simple. Compared with traditional finished pressure sensors, it has a wider range of applications and a lower failure rate, which reduces production costs and ensures production safety.

[0023] 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 some embodiments of the utility model, not all embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0025] Figure 1-Figure 5 This is a specific embodiment of the utility model, which is a filling pipeline pressure monitoring component. The pressure measuring cylinder 1 is a square cylinder. An ordinary pressure gauge 5 is installed on the top of the pressure measuring cylinder 1. A hand pressure pump 3, an exhaust needle valve 6, a pressure sensor reserved interface 11, and a safety valve 7 are installed on the four sides of the pressure measuring cylinder. An oil separator 2 is installed between the hand pressure pump 3 and the pressure measuring cylinder 1. A one-way valve 4 is installed above the oil separator 2 to prevent the hydraulic oil from flowing back during fluid replenishment. The hand pressure pump 3 mainly plays the role of initial pressure replenishment and fluid replenishment for the pressure measuring cylinder 1. The other end of the pressure measuring cylinder 1 is a mounting flange, and a high-elastic rubber sheet 9 is installed at the flange end. The high-elastic rubber sheet 9 is fixed to the bottom of the pressure measuring cylinder through a pressure cover 8. At the same time, an O-ring 10 is provided on the pressure cover to effectively prevent oil and liquid leakage.

[0026] Before installation, inject hydraulic oil into the pressure measuring cylinder 1 through the oil filling port 201 on the oil distributor 2 in conjunction with the hand pump 3, and exhaust the internal air in time through the exhaust needle valve 6 to prevent measurement errors caused by air compression. After the air is exhausted, continue to pressurize until the pointer of the pressure gauge 5 jumps, and set it as the initial pressure value. Connect the pressure monitoring component to the filling pipeline through the base flange of the pressure measuring cylinder 1.

[0027] After the installation is completed, the high-elastic film 9 of the pressure monitoring component is connected to the pipeline. When the fluid in the filling pipeline flows through the pressure monitoring component, the fluid impacts the high-elastic film 9, and the film undergoes elastic deformation and reverse arching (such as Figure 3 As shown), the internal hydraulic oil is squeezed through the pressure gauge 5. The safety valve 7 can ensure the initial pressure of the pressure measuring cylinder 1, and at the same time prevent the pressure measuring cylinder 1 and the sensor from being damaged by pressure overload due to pipeline overpressure, thus playing a protective role.

[0028] After being used or left idle for a period of time, the air mixed in the cylinder and the different compression ratios of air and hydraulic oil will cause deviations in the monitoring data. At this time, it is necessary to open the needle valve 6 to remove the air in the pressure measuring cylinder 1, and then replenish the pressure again through the hand pump 3. The pressure sensor reserved interface 11 on one side of the pressure measuring cylinder 1 can be connected to an electronic pressure sensor, which can remotely monitor the pressure data and realize the digital transmission of the pipeline pressure data, which is convenient for automated integrated control and ensures the safety of pipeline filling.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
