Abstract

A gate valve is to consist of: valve body, valve gap, locating slot, locating sealing ring, packing groove, filler, Gland, nut, valve rod, valve rod positioning block, hand wheel component, flashboard; Between valve body and nut, valve gap is set, valve body, valve gap and nut middle part arrange valve rod, and valve rod middle part arranges valve rod positioning block, and valve rod top correspondence arranges hand wheel component, and valve rod below correspondence arranges flashboard; In described valve gap, below arranges locating slot; Adopt malleable cast iron manufacture to form, can use for a long time, not easy to crack, good toughness, intensity is high, guarantees water quality, rapid operation good sealing effect.

Description

A kind of gate valve
Technical field
The utility model relates to valve field, especially a kind of gate valve.
Background technique
At present, adopt two valve gaps on market between the valve body of gate valve and nut, between each parts, all adopt and be threaded, for a long time through water slug, the position being threaded just can produce corrosion, thus polluted water, and easily wear and tear, affect the working life of gate valve.
Through retrieval, application number is that 982294522 patent document has been announced a kind of soft sealing gate valve, by using soft material to improve the anticorrosive of gate valve, but this sealing surface of the discharge gate is little, and easily wearing and tearing, particularly when having impurity to be sandwiched in sealing surface place, easily cause poorly sealedly, occur leakage phenomenon, and weight is large, during operation, require great effort, directly affect the normal use of gate valve.
In view of the foregoing, the structure of existing gate valve needs to improve.
Model utility content
The purpose of this utility model is in order to overcome deficiency of the prior art, and a kind of gate valve is provided, and adopts malleable cast iron manufacture to form, and can use for a long time, not easy to crack, good toughness, and intensity is high, guarantees water quality, rapid operation good sealing effect.
The utility model to achieve these goals, adopt following technological scheme: a kind of gate valve is to consist of: valve body, valve gap, locating slot, locating sealing ring, packing groove, filler, Gland, nut, valve rod, valve rod positioning block, hand wheel component, flashboard; Between valve body and nut, valve gap is set, valve body, valve gap and nut middle part arrange valve rod, and valve rod middle part arranges valve rod positioning block, and valve rod top correspondence arranges hand wheel component, and valve rod below correspondence arranges flashboard; In described valve gap, below arranges locating slot.
Valve rod positioning block is set in described locating slot, and valve rod positioning block periphery arranges locating sealing ring, locating sealing ring setting corresponding to locating slot.
In described valve gap, top arranges packing groove, and filler is set in packing groove, and between valve gap upper end and nut, corresponding filler arranges Gland.
The cross section of described locating sealing ring is crescent shape or arc.
The beneficial effects of the utility model are: the utility model reduces product shape size, energy-conserving and environment-protective; Reduce the existence of coupling nut machining error, product is opened and closed flexibly; Location in valve rod adopts, reduces by a leakage point, safety and reliability, and performance is better; Reducing coupling nut part makes product appearance more graceful.
The utility model adopts malleable cast iron manufacture to form, and compares with the gray cast iron on market, and summer in the winter amount of deformation that expands with heat and contract with cold is little, uses for a long time, not easy to crack, good toughness, and intensity is high; Rational in infrastructure, good seal performance, lightweight, easily, quality is good, not fragile in operation; Rotation hand wheel assembly, moves up and down valve rod, and valve rod positioning block moves up and down the moment of torsion of controlling valve rod in locating slot, compare with existing gate valve structure, the utility model has shortened moment of torsion, use more convenient, convenient maintenance and replacement, good sealing effect, long-term use, does not produce corrosion, guarantees water quality, rapid operation, increases the service life.
