Abstract
The utility model relates to a lifting no-corrosion water type bottom valve of a non-return water pump inlet and an outlet for preventing medium from counter flow. A valve disc (5), a pressed nitrile rubber sealing gasket (6) and a sealing gasket press plate (7) form a valve clack to replace the original piston clack, and the form of a piston is not used any more. When the water pump supplies water, the suction force generated by the water pump enables the valve clack to move upward and the valve to open without friction, the valve clack is light, and the sealing is more reliable. When the water pump stops water supply, the valve clack restores to close the valve and stop the medium from counter flow due to the counter flow acting force of the medium and the self weight of the valve clack; valve rod positioning holes are arranged on a casting valve seat supporting frame (8); two-direction positioning by the positioning hole for a valve rod guide sleeve (4) and the positioning hole for a supporting frame valve rod (4) enable the valve clack not to swing; and the valve seat supporting frame (8) is installed at the angular corner to facilitate the shortening of the travel of the valve clack, reduce the height of the valve rod guide sleeve (1) and save materials and installation space.
Description
Technical field
The utility model relates to a kind of nonreturn type water pump inlet/outlet to be prevented to make the valve rod positioning hole on control gear, the especially support at the bottom of the lifting of medium counter flow from not having the wearing and tearing above-water type, prevents that the valve disc swing from reaching and do not have wearing and tearing and prevent the medium counter flow effect.
Background technique
The above-water type bottom valve that existing market adopts mainly is made up of valve gap, valve rod, piston, sealing gasket, sealing gasket pressing plate and valve body.When water pump supplied water, the suction of water pump impelled the piston lobe to open, and supplies water.The piston lobe to hydrodynamic reciprocating sealing, prevents that medium from flowing backwards by dead weight when stopping to supply water.At present this valve is in the use because the friction of piston lobe and valve interior wall is excessive, the overweight pump power that causes of piston lobe is crossed low and can't be opened.Do not use valve interior wall corrosion piston lobe to open for a long time.After the piston lobe is opened and broken away from piston cylinder, only deposit the location, conduit one place of valve rod top, be directed at the piston lobe swing, use the valve rod bending of long-time back to cause the piston lobe to reset, can not throttle down.Because piston lobe stroke height, valve gap top valve rod positioning pipe is too high to making, and it is big to make cost of material increase requirements of installation space.
Summary of the invention
The friction of existing above-water type bottom valve piston lobe and valve interior wall is excessive, the piston lobe is overweight, and the piston lobe lacks the location after opening, piston lobe stroke height, and it is excessive to make cost of material increase requirements of installation space.The utility model provides a kind of lifting not have wearing and tearing above-water type bottom valve, and this valve uses valve disc, sealing gasket and sealing gasket pressing plate to replace original piston lobe, the cancellation piston; Increase the valve seat support, make the valve rod positioning hole on the support, prevent the valve disc swing; The valve seat support is installed in the dihedral corner, shortens valve disc travel.
Technological scheme: casting valve disc and sealing gasket pressing plate, compacting nitrile butadiene rubber sealing gasket are combined into flap and replace original piston lobe, do not re-use the form of piston, can not produce friction, and flap is light, seals more reliable; The cast valve seat support is made the valve rod positioning hole on support, valve rod guide pin bushing and support valve rod positioning hole two sides location are no longer swung flap; The valve seat support is installed in the dihedral corner, and just the flap stroke shortens, and shortens the valve stem casing height, economical with materials and installing space.
Beneficial effect is: economical with materials and installing space, shorten valve disc travel, and make things convenient for user installation and use, can not produce friction, flap can not swung.
Description of drawings
Fig. 1 is product design figure, and Fig. 2 is product structure figure.
Among the figure, 1, valve rod guide pin bushing 2, valve gap 3, valve body 4, valve rod 5, valve disc 6, compacting nitrile butadiene rubber sealing gasket 7, sealing gasket pressing plate 8, valve use of revenue to finance expense frame.
Embodiment
A kind of nonreturn type water pump is imported and exported the lifting that prevents medium counter flow does not have wearing and tearing above-water type bottom valve.By valve disc (5) and, compacting nitrile butadiene rubber sealing gasket (6) sealing gasket pressing plate (7) is combined into flap and replaces original piston lobe, do not re-use the form of piston, when water pump supplies water, the suction that water pump produces moves up flap, and valve opening can not produce friction, flap is light, seals more reliable.Because medium counter flow is done firmly and the flap self gravitation, make the flap throttle down that resets when water pump stops to supply water, do not allow medium flow backwards; Cast valve seat support (8) is made the valve rod positioning hole on support, valve rod guide pin bushing (1) and support valve rod (4) positioning hole two sides location are no longer swung flap; Valve seat support (8) is installed in the dihedral corner, and just the flap stroke shortens, and shortens valve rod and leads (1) cover height, economical with materials and installing space.
Claims (4)
1, a kind of nonreturn type water pump is imported and exported the lifting that prevents medium counter flow does not have wearing and tearing above-water type bottom valve, mainly form by valve gap, valve stem casing, valve rod, flap, valve body etc., it is characterized in that: flap is by casting valve disc and sealing gasket pressing plate, and compacting nitrile butadiene rubber sealing gasket combines; Valve use of revenue to finance expense frame is installed in the corner of dihedral valve body; Valve seat carriage center processing valve rod positioning hole,
2, do not have wearing and tearing above-water type bottom valve as lifting as described in claims 1, it is characterized in that flap opens and closes with valve interior wall not produce friction.
3, do not have wearing and tearing above-water type bottom valve as lifting as described in claims 1, it is characterized in that the flap stroke shortens, stroke shortens back valve stem casing length and also shortens simultaneously.
4, there is not wearing and tearing above-water type bottom valve as lifting as described in claims 1, its feature valve stem casing and valve seat rack positioning hole two sides location, flap is no longer swung in opening-closing process.
