Fig. 3 is an installation schematic diagram of a flow guide block in the eccentric half ball valve of the present invention.
In the figure: the valve comprises a valve body 1, a flow channel 2, a liquid outlet end 3, a liquid inlet end 4, a valve rod 5, a hemispherical valve plate 6, a cylinder body 7, a buffer block 8, a valve seat 9, a sealing ring 10, a buffer spring 11, a flow guide block 12, a sealing filler 13 and a filler gland 14.
Detailed Description
The present invention will now be further described with reference to the accompanying drawings and specific embodiments.
The first embodiment is as follows:
referring to fig. 1 and 2, the embodiment of the utility model discloses an it is eccentric hemisphere valve to disclose, including valve body 1, hemisphere valve plate 6 and valve rod 5, runner 2 has in the valve body 1, and the one end of runner 2 forms feed liquor end 4, the other end forms out liquid end 3, is close to feed liquor end 4 one side fixed mounting in the runner 2 and has disk seat 9, and hemisphere valve plate 6 rotates and installs in runner 2 of valve body 1, and hemisphere valve plate 6's ectosphere and disk seat 9 seal fit, the annular has been seted up on hemisphere valve plate 6 and the ectosphere of disk seat 9 cooperation part, embedding sealing washer 10 in the annular. Valve rod 5 rotates and installs on valve body 1, the bottom and the 6 fixed connection of hemisphere valve plate of valve rod 5, in order to realize the linkage of valve rod 5 and hemisphere valve plate 6, hemisphere valve plate 6's turned angle is 0-90 degrees scope, when hemisphere valve plate 6's horizontal axis and disk seat 9 axis coincide promptly, the rotation angle of definition for hemisphere valve plate 6 is 0 degrees, at this moment, the valve is in the closed condition, when hemisphere valve plate 6's horizontal axis is perpendicular with disk seat 9 axis, the rotation angle of definition for hemisphere valve plate 6 is 90 degrees, at this moment, the valve is in the open mode.
When the valve is closed in the twinkling of an eye, inlet end 4 can form great water hammer in valve body 1, and water hammer strikes valve body 1 and hemisphere valve plate 6, in order to reduce the water hammer impact force, this hemisphere valve plate 6 is gone up to inwards sunken and is formed barrel 7, this barrel 7 with hemisphere valve plate 6 coaxial distribution, the one end that is close to hemisphere valve plate 6 on the barrel 7 is the open end, slidable mounting has buffer block 8 in the barrel 7, be connected with the elastic component between the bottom of this buffer block 8 and barrel 7. When the valve is closed in the twinkling of an eye, there is the water hammer that the pressurized-water formed to fill to hit on this buffer block 8, and buffer block 8 compresses towards barrel 7 bottom, and the elastic component extrusion energy storage cushions the impact force of water hammer to avoid hemisphere valve plate 6 to receive direct impact.
In this embodiment, the elastic member is specifically a buffer spring 11, and the buffer spring 11 has a plurality of ends, and both ends of the buffer spring are connected to the bottom of the buffer block 8 and the bottom of the cylinder 7 respectively. Besides, the elastic piece can also adopt an elastic sheet or a rubber elastic cushion, and can play a role in energy storage and buffering.
In order to avoid erosion to the elastic part caused by fluid entering a sealing cavity between the cylinder 7 and the buffer block 8, an annular packing groove is formed in the periphery of the buffer block 8, a sealing packing 13 is filled in the packing groove, and a packing gland 14 for extruding and sealing the sealing packing 13 is fixedly installed at an opening at the front end of the packing groove.
When the hemispherical valve plate 6 rotates to 90 degrees, at this time, the central axis of the hemispherical valve plate 6 is perpendicular to the axis of the valve seat 9, the flow channel 2 of the valve is in a fully open state, and the existence of the inward recessed cylinder 7 increases the water flow resistance, in order to solve this problem, referring to fig. 3, in this embodiment, preferably, the flow guide blocks 12 are integrally formed on both sides of the outer side of the cylinder 7, the flow guide blocks 12 extend transversely, the cross-sectional thickness of the flow guide blocks gradually decreases from the near end close to the cylinder 7 to the far end, and a flow guide edge is formed at the far end of the flow guide blocks 12. Through the arrangement of the flow guide block 12, the flow guide block 12 and the periphery of the cylinder 7 jointly form a streamline flow guide surface, and fluid is divided by the flow guide edge and flows through the flow guide surfaces on the upper side and the lower side, so that the fluid resistance is greatly reduced, and the smooth flow of the fluid is ensured.
Modifications and variations of the present invention are within the scope of the claims and are not limited by the disclosure of the embodiments.
