Technical Field

[0001] The utility model belongs to the technical field of mud pump gate valves, and in particular relates to a mud pump gate valve structure capable of reducing wear. Background Art

[0002] Mud gate valve, also known as knife gate valve, is used in coal preparation, gangue and slag discharge in mines and power plants to urban sewage treatment, and from general industrial pipelines to professional pipeline systems such as food, health and medicine.

[0003] The existing mud pump gate valve structure on the market has the following problems in actual use:

[0004] 1. When the traditional mud pump gate valve structure is actually used, due to the repeated installation and removal of the pipeline, the position where the mud pump gate valve structure is installed in the pipeline will be worn. After long-term use, the wear will gradually increase, and the wear efficiency during use is high;

[0005] 2. During the use of most mud pump gate valve structures, it is necessary to rotate the turntable on the mud pump gate valve structure when opening and closing the gate. At this time, the force point and center of the turntable are close, which makes it very laborious to close or open the gate and is inconvenient to use. Utility Model Content

[0029] In order to better understand the purpose, structure and function of the utility model, the utility model is described in further detail below in conjunction with the accompanying drawings.

[0030] like Figure 1-6 As shown, a mud pump gate valve structure with reduced wear of the utility model comprises a mud gate valve body 1, a flange 2 is welded on the surface of the mud gate valve body 1, a clamping ring 5 is installed on the surface of the flange 2, a magnet ring 6 is clamped inside the clamping ring 5, and by installing the magnet ring 6 and the iron ring 7, when the gasket 8 is embedded in the inside of the clamping ring 5, the magnet ring 6 will contact with the iron ring 7. At this time, the gasket 8 can be adsorbed and fixed inside the clamping ring 5 by the magnetic attraction effect, so that the gasket 8 has a follow-up effect and is very convenient to use. The gasket 8 is clamped inside the clamping ring 5, and the iron ring 7 is bonded inside the gasket 8. The surface of the iron ring 7 fits the magnet ring 6, and the other end of the gasket 8 protrudes from the flange 2. By installing the gasket 8, and one end of the gasket 8 protrudes from the flange 2, when the flange 2 is installed on the pipeline, it first touches the gasket 8. The gasket 8 can provide an anti-wear effect for the installation position of the flange 2, thereby reducing the wear of the flange 2 during use.

[0031] A turntable 10 is installed on the top of the mud gate valve body 1, and a reinforcing rod 11 is fixedly connected inside the turntable 10. A slide groove 13 is provided inside the reinforcing rod 11, and a telescopic rod 14 is sleeved inside the slide groove 13. A stopper 15 is welded on the side of the telescopic rod 14. By installing the telescopic rod 14, the distance between the palm force point and the rotation center position is lengthened by the telescopic rod 14, that is, the fulcrum is lengthened. At this time, the telescopic rod 14 can be used to directly drive the turntable 10 to rotate, which is very labor-saving when used.

[0032] A fixing ring 3 is welded on the surface of the flange 2, a positioning hole 4 is provided on the side of the fixing ring 3, an externally threaded rod 9 is welded on the side of the clamping ring 5, the externally threaded rod 9 passes through the positioning hole 4, a nut 19 is installed on the surface of the externally threaded rod 9, and the surface of the nut 19 fits the fixing ring 3. By installing the fixing ring 3 and providing the positioning hole 4 on the side of the fixing ring 3, an installation position can be provided for the clamping ring 5. When the clamping ring 5 needs to be installed, the externally threaded rod 9 on the side of the clamping ring 5 is directly passed through the positioning hole 4, and the nut 19 is installed to fix it. It is very convenient to use.

[0033] The side of the iron sheet 17 is fixedly connected to the fixing seat 18, and the other end of the fixing seat 18 is welded with a handle 12, which is distributed in a ring form. By installing the handle 12, when the turntable 10 needs to be rotated by the telescopic rod 14, the handle 12 can be directly used to apply force to it, which is very convenient to use.

[0034] A magnet sheet 16 is bonded to one end of the reinforcing rod 11, and an iron sheet 17 is welded to the surface of the telescopic rod 14. The side of the iron sheet 17 is fitted to the magnet sheet 16. By installing the magnet sheet 16 and the iron sheet 17, when the telescopic rod 14 is embedded in the slide groove 13, the magnet sheet 16 will contact the iron sheet 17. At this time, the iron sheet 17 can be adsorbed and fixed on the reinforcing rod 11 by utilizing the magnetic attraction effect, thereby providing a fixing effect for the telescopic rod 14, which is very convenient to use.

[0035] The reinforcing rods 11 are distributed in a ring shape, and the telescopic rods 14 are distributed in a ring shape. The reinforcing rods 11 are installed in a distributed manner to evenly reinforce the turntable 10, so that the turntable 10 will not be easily deformed and has a higher strength when in use.

[0036] The working principle of the mud pump gate valve structure with reduced wear: when using the mud pump gate valve structure with reduced wear, the gasket 8 should be embedded into the clamping ring 5 first, and then the magnet ring 6 will contact the iron ring 7. At this time, the gasket 8 can be adsorbed and fixed inside the clamping ring 5 by using the magnetic attraction effect, and then the external threaded rod 9 on the side of the clamping ring 5 is passed through the positioning hole 4 on the side of the fixing ring 3, and the nut 19 is installed to fix it, and then the flange 2 can be installed with the pipeline. When the flange 2 is used to install the pipeline, the first thing it touches is the gasket 8. The gasket 8 can provide an anti-wear effect for the installation position of the flange 2. After a long period of use, when the gasket 8 is worn, the gasket 8 can be directly pulled out, and then it can be replaced with a good gasket 8. At this time, after long-term use The wear of the mud pump gate valve structure at the installation position of the pipeline can be reduced. When it is necessary to open or close the valve during the use of the mud pump gate valve structure with reduced wear, if it is more laborious to rotate the turntable 10, the telescopic rod 14 can be pulled out. When it is pulled to a suitable position, the telescopic limit is limited inside the slide groove 13 by using a block. At this time, the telescopic rod 14 is used to lengthen the distance between the palm force point and the rotation center position, that is, the fulcrum is lengthened. At this time, the telescopic rod 14 can be used to directly drive the turntable 10 to rotate, which is very labor-saving when used. After the valve is opened or closed, the telescopic rod 14 can be embedded in the slide groove 13, and then the magnet sheet 16 will contact with the iron sheet 17. At this time, the iron sheet 17 can be adsorbed and fixed on the reinforcing rod 11 by using the magnetic attraction effect, and then the telescopic rod 14 can be retracted.
