Technical Field

[0001] The utility model relates to valve-related fields, in particular to a high-sealing valve turbine head. Background Art

[0002] A valve is a device used to control the flow direction and pressure of a fluid in a pipeline system. The function of a valve is to regulate and control the flow of the fluid to meet specific requirements, such as controlling flow, pressure, temperature, etc. Valves are widely used in the fields of petroleum, chemical industry, electric power, metallurgy, pharmaceuticals, food, etc., and are a very important pipeline equipment. A valve turbine head is a common mechanical equipment, mainly used for the opening and closing control of valves. A valve turbine head is set in some valves that control water flow, gas flow or other liquid flow. A valve turbine head is a valve accessory, usually used to control the flow of liquid, gas or other fluids, to ensure that the pressure and flow in the pipeline are properly controlled and regulated.

[0003] In order to prevent dust and impurities from entering the valve turbine head through the gap between the driving rod and the valve turbine head and affecting its internal parts when the manual valve turbine head is in use, a sealing ring is usually set on the valve turbine head. However, a simple sealing ring may become loose and have a gap with the driving rod after long-term use, thereby affecting the sealing of the valve turbine head, making it easy for external dust and impurities to enter the interior, causing the internal parts of the valve turbine head to run unsmoothly, which is not conducive to the stable use of the valve turbine head.

[0007] Preferably, the outer top of the sealing rubber sleeve and the inner ring of the extrusion ring are gradually contracted from bottom to top to form an inclined surface, and the inclined surfaces on the sealing rubber sleeve and the extrusion ring are parallel to each other.

[0021] like Figures 1 to 3 As shown, in this embodiment, a T-slot 7 coaxially arranged with the driving rod 2 is provided on the turbine head body 1, the inner ring of the T-slot 7 covers the connecting portion between the driving rod 2 and the turbine head body 1, and a hollow fixing sleeve 5 movably connected with the driving rod 2 is locked and fixed on the outer surface of the turbine head body 1, and a sealing ring 6 is installed on the inner ring of the fixing sleeve 5, and the inner ring of the sealing ring 6 is fitted to the outer surface of the driving rod 2, so as to improve the sealing performance of the connection between the driving rod 2 and the fixing sleeve 5;

[0022] A sealing rubber sleeve 8 is movably inserted into the T-slot 7, and an extrusion ring 9 for pressing and fixing the sealing rubber sleeve 8 is installed on the top of the inner side of the T-slot 7. The extrusion ring 9 applies pressure to the sealing rubber sleeve 8 to improve the sealing performance of the sealing rubber sleeve 8 connected to the driving pipe 2;

[0023] The inner ring of the sealing rubber sleeve 8 is in contact with the outer surface of the driving rod 2 to enhance the sealing performance of the driving rod 2 connected to the turbine head body 1, and the sealing rubber sleeve 8 is provided with a plurality of collecting grooves 11 along the inner circumferential direction to collect dust and impurities on the driving rod 2;

[0024] The outer top of the sealing rubber sleeve 8 and the inner ring of the extrusion ring 9 are gradually contracted from bottom to top to form an inclined surface 10, and the inclined surfaces 10 on the sealing rubber sleeve 8 and the extrusion ring 9 are parallel to each other, so that the extrusion ring 9 can squeeze the sealing rubber sleeve 8 to fit smoothly on the outer surface of the driving rod 2 through the inclined surface 10;

[0025] In this embodiment: a reinforcing ring 12 is fixedly installed on the inner side of the sealing rubber sleeve 8, and the reinforcing ring 12 is located above the collecting groove 11 to improve the sealing performance of the connection between the turbine head body 1 and the driving rod 2;

[0026] In this embodiment, an annular groove 13 is formed on the side surface of the driving rod 2, and the inner side of the annular groove 13 is movably connected to the reinforcement ring 12, so that the sealing performance of the driving rod 2 connected to the turbine head body 1 can be improved by cooperating with the annular groove 13 through the reinforcement ring 12;

[0027] In this embodiment, the reinforcing ring 12 is made of silicone, which has good high temperature resistance and corrosion resistance and a long service life;

[0028] The collecting grooves 11 in the sealing rubber sleeve 8 are distributed in an annular shape with equal spacing, so as to facilitate the collection of dust and impurities on the driving rod 2;

[0029] In this embodiment, the extrusion ring 9 is locked and fixed in the T-slot 7 by the long screw 14, and the sealing rubber sleeve 8, the extrusion ring 9 and the long screw 14 are all located inside the fixing sleeve 5, which improves the stability of the installation of the extrusion ring 9, so that the extrusion ring 9 applies a stable pressure to the sealing rubber sleeve 8, thereby improving the stability of the sealing rubber sleeve 8 during use;

[0030] When in use, the sealing rubber sleeve 8 is placed in the T-slot 7, and the extrusion ring 9 is installed in the T-slot 7 by the long screw 14. When installing, the inclined surface 10 of the inner ring of the extrusion ring 9 squeezes the inclined surface 10 of the outer surface of the sealing rubber sleeve 8, so that the sealing rubber sleeve 8 is pressed by the extrusion ring 9 and fits on the outer surface of the driving rod 2. The sealing rubber sleeve 8 drives the reinforcement ring 12 to enter the annular groove 13, and then the fixing sleeve 5 drives the sealing ring 6 to be installed on the worm head body 1;

[0031] The sealing ring 6, sealing rubber sleeve 8 and reinforcing ring 12 arranged in the valve worm gear head provide multiple seals between the turbine head body 1 and the driving rod 2, thereby improving the sealing performance of the driving rod 2 connected to the turbine head body 1. The sealing rubber sleeve 8 is stably fitted on the outer surface of the driving rod 2 by the pressure of the extrusion ring 9, thereby reducing the loosening of the sealing rubber sleeve 8, thereby reducing the external dust and impurities from entering the turbine head body 1 through the gap between the driving rod 2 and the turbine head body 1. When the driving rod 2 rotates, it rubs against the inner ring of the sealing rubber sleeve 8. The sealing rubber sleeve 8 can scrape the dust and impurities remaining on the driving rod 2 into the collecting groove 13, thereby further reducing the dust entering the turbine head body 1, which is beneficial to improving the smoothness of the valve turbine head during use.
