[0031] The present invention will be further described below in conjunction with the accompanying drawings and implementation modes.

[0032] First embodiment

[0033] Please refer to Figure 1 ,in, Figure 1 The present invention provides a schematic structural diagram of a first embodiment of a multifunctional tubular diaphragm pump for grouting and filling. A multifunctional tubular diaphragm pump for grouting and filling comprises:

[0034] A flow pipe 9, the left end of which is connected to a diaphragm tube 2, a diaphragm 3 is provided inside the diaphragm tube 2, and a diaphragm tube sealing gasket 4 is provided between the diaphragm tube 2 and the flow pipe 9;

[0035] A discharge valve housing 5 is provided at the top of the flow pipe 9, a valve assembly 7 is provided inside the discharge valve housing 5, a suction valve housing 10 is connected to the right end of the flow pipe 9, and a valve gland 6 is provided at the top of the discharge valve housing 5.

[0036] A diaphragm tube flange 1 is provided at one end of the diaphragm tube 2 .

[0037] A discharge flange 8 is provided at the right end of the discharge valve housing 5 .

[0038] A suction flange 11 is disposed at the right end of the suction valve housing 10 .

[0039] The diaphragm 3 is a tubular diaphragm with one end closed and the other end open, and the open end has a flange sealing function.

[0040] The material of the diaphragm 3 is high-strength rubber, which is resistant to abrasion and corrosion, and the suction and discharge of the conveying medium is achieved through the injection and discharge of the power fluid.

[0041] High-strength rubber can be: chloroprene rubber, nitrile rubber and EPDM rubber. Chloroprene rubber has excellent oil resistance, solvent resistance and wear resistance, and can withstand a variety of chemicals at room temperature; nitrile rubber has good oil resistance and wear resistance, and is suitable for the transmission of various oil media and general chemicals; EPDM rubber has excellent heat resistance, aging resistance and ozone resistance, as well as good acid and alkali resistance and solvent resistance, and is often used in sanitary applications such as drinking water and sewage treatment.

[0042] The diaphragm 3 isolates the transported medium from the driving mechanism and transmission components of the pump, preventing the medium from leaking to other parts of the pump and causing damage such as corrosion and wear to these components, thereby ensuring the normal operation of the pump and extending its service life.

[0043] Produce suction and discharge effects: During the working process of the pump, the diaphragm changes the volume of the pump chamber through its own reciprocating motion. When the diaphragm stretches backward, the volume of the pump chamber increases, forming a negative pressure, so that the medium is sucked into the pump chamber through the suction valve; when the diaphragm contracts forward, the volume of the pump chamber decreases, the medium is squeezed, and discharged from the pump chamber through the discharge valve, realizing the suction and discharge of the medium, and achieving the purpose of conveying materials.

[0044] The power source of the tubular diaphragm pump is provided by an independent high-pressure plunger pump. The high-pressure plunger pump causes the deformation of the diaphragm 3 by sucking and discharging the power fluid, driving the opening and closing of the suction and discharge valve assembly, and finally realizing the suction and discharge of the conveying medium;

[0045] The pumping speed of the tubular diaphragm pump is determined by the pumping speed of the high-pressure plunger pump. By adjusting the pumping speed of the high-pressure plunger pump, the pumping speed of the tubular diaphragm pump can be adjusted to meet the transportation requirements of different types of media.

[0046] The type of power fluid is not limited to hydraulic oil, emulsion, water and other media, and the driving mode of the high-pressure plunger pump is not limited to motor, diesel engine, hydraulic pressure, etc.;

[0047] The valve assembly 7 adopts the same design, with upper and lower guides, metal / non-metallic cone valve, and low pump speed characteristics, which can effectively increase the valve core jump height, facilitate the passage of large particle media, improve the flow capacity of the pump group, and meet the needs of wide adaptability of the pump group working conditions;

[0048] The tubular diaphragm pump can increase the discharge flow rate by combining multiple groups of single-tube diaphragm pumps. Any number of combinations can be achieved according to the requirements of on-site usage parameters. At the same time, backup can be achieved by setting up additional 1 to 2 diaphragm tubes for switching. There is no need to set up a separate complete pump group as a backup pump like a traditional pump group.

[0049] The entire device controls the change in the volume of the tubular diaphragm through the suction and discharge of the power fluid, thereby realizing the suction and discharge of the conveying medium in the diaphragm cavity, and realizing the suction and discharge of the conveying medium through the change of volume.

[0050] This device combines the filling function of an industrial filling pump and the grouting function of a grouting pump, fundamentally solving the problem of needing multiple equipment to realize filling and grouting operations, with high and low integration. At the same time, this device can realize multiple uses of one pump, and is suitable for conveying different slurries for mine filling and grouting operations.

[0051] Valve seat: It is the basic component of the valve assembly, used to install and fix other valve assembly parts. It usually has good sealing and stability to ensure the normal operation of the valve. Its material is generally selected according to the properties of the conveying medium and the working environment. For example, for some corrosive media, corrosion-resistant plastics or ceramics will be used.

[0052] Valve ball: It is one of the key components to realize the opening and closing function of the valve. During the operation of the pump, the valve ball controls the inflow and outflow of the fluid by moving in the valve seat. When the valve ball fits tightly against the valve seat, the valve is closed to prevent the fluid from passing through; when the valve ball leaves the valve seat, the valve opens to allow the fluid to flow. The material of the valve ball usually has high hardness and wear resistance, such as ceramic valve ball, which has good corrosion resistance and wear resistance, and can maintain good sealing performance in long-term operation.

[0053] Valve cover: It is mainly used to protect the internal parts of the valve to prevent external impurities from entering the valve and affecting its normal operation. It also plays a certain sealing role to ensure the isolation of the valve assembly from the external environment. The material of the valve cover is generally matched with the valve seat to ensure the sealing and corrosion resistance of the entire valve assembly.

[0054] Spring: Provides elastic force for the valve ball so that the valve ball can remain closed under normal circumstances and respond promptly when the pressure changes to realize the opening and closing of the valve. The elastic coefficient of the spring needs to be reasonably selected according to the specific working pressure and flow requirements to ensure the sensitivity and reliability of the valve.

[0055] Sealing ring: installed in the matching parts between the valve seat and the valve cover, the valve ball and the valve seat, etc., to enhance the sealing effect and prevent fluid leakage. The material of the sealing ring usually has good elasticity and corrosion resistance, such as rubber sealing ring, etc., which can maintain effective sealing performance under different working conditions.

[0056] Gasket: Generally placed between the valve seat and other components, it plays the role of adjusting the gap, evenly distributing the pressure and enhancing the seal, ensuring the close fit between the components of the valve assembly and preventing the fluid from leaking from the gaps between the components.

[0057] Pipe core: It is a component that connects the pipeline and the valve seat, and plays the role of guiding the flow of fluid so that the fluid can smoothly enter and flow out of the valve assembly.

[0058] Compared with the related art, the multifunctional tubular diaphragm pump for grouting and filling provided by the present invention has the following beneficial effects:

[0059] The present invention provides a multifunctional tubular diaphragm pump for grouting and filling. Through the cooperation of a diaphragm tube 2, a diaphragm 3, a diaphragm tube sealing gasket 4, a discharge valve housing 5, a valve gland 6, a valve assembly 7, a flow-through pipe fitting 9 and a suction valve housing 10, based on the characteristics of the pump group invention, one pump can be used for multiple purposes, and has a wide range of adaptability to working conditions. It can meet the two extreme working conditions of filling and grouting conditions, as well as all working conditions between the two extreme working conditions. For working conditions such as water injection, drainage, and oil transportation, the pump group can also meet the transportation requirements under full rated parameters.

The inner wall of the placement groove 12 is provided with a plurality of mounting grooves 133 adapted to the plurality of mounting blocks 132 .

[0064] One end of the diaphragm 3 is connected to one side of the mounting ring 131. The use of the mounting block 132 and the mounting groove 133 facilitates the separation of the mounting ring 131 from the placement groove 12. The use of the fixing ring 141, the disassembly block 142 and the disassembly groove 143 can play a fixing role after the mounting ring 131 is installed inside the placement groove 12.

[0066] A plurality of disassembly grooves 143 adapted to the plurality of disassembly blocks 142 are formed on the inner wall of the placement groove 12 .

[0067] The working principle of a grouting and filling multifunctional tubular diaphragm pump provided by the present invention is as follows:

After the fixing ring 141 is taken out, the diaphragm 3 inside the diaphragm tube 2 is pulled outward by pulling the installation ring 131. When the installation ring 131 is pulled outward, the installation block 132 is separated from the installation groove 133 opened on the placement groove 12, and the diaphragm 3 can be taken out of the diaphragm tube 2 using the installation ring 131.
