Description

A kind of Liquid valve
Technical field
The utility model is related to valve, particularly a kind of Liquid valve, can be widely applied to petrochemical industry, crude oil and opens Adopt and convey, in the production of the numerous areas such as metallurgical mine and life.
Background technology
At present, the valve used in production, life is due to opening and closing part, namely the valve element exposed fluid in valve completely In passage, different fluids are washed away after abrasion or soda acid salt corrosion or fouling occupy-place to opening and closing part, keying part is closed not Sternly, defective valve is caused, its service life is short, changes frequency height, dead volume is more, causes substantial amounts of human and material resources and warp Ji loss, have impact on normal production and lives.Some units or family just allow interchangeable to reduce the cost input of replacing valve The valve that can not be changed is gone to work braving one's illness, and will be delayed again and again with using, and the equipment or pipeline in producing, living are damaged suddenly, Because defective valve can not be closed, production, life accident that thus leaked liquid trigger is caused to be controlled in time, to the person And property causes very big economic loss, while also being worked to repair and replacement, difficulty is added.
The content of the invention
The purpose of this utility model is to provide a kind of Liquid valve, solve existing valvular valve element completely it is exposed in a fluid Abrasion, corrosion and the fouling occupy-place problem caused, makes the valve element of valve is not exposed under unlatching and closed mode to be situated between in fluid In matter, medium abrasion, corrosion and fouling occupy-place is reduced or avoided, using effect is improved, extends the service life of valve.
Technical solution of the present utility model is:A kind of Liquid valve includes valve rod and valve body, and the front end of valve rod is valve Core, valve body is arranged in valve body provided with outlet, valve element, and valve element is respectively provided with the body of valve outlet both sides and opens protection Set and valve element close protective case, and valve element, which is arranged in valve element unlatching protective case and can screw in valve element by valve rod, closes protective case In, the two ends of valve body are respectively provided with gland and pipe joint.
Compared with prior art, the beneficial effects of the utility model are:
This valve uses wear-resisting, oil resistant corrosion-resistant material, and such as stainless steel, nylon, rubber material make valve element and opened Protective case and valve element close protective case, and valve is under the state that is turned on and off, and the face of cylinder of its valve element is not exposed to be situated between in fluid In matter, from exposed caused abrasion, corrosion and fouling occupy-place problem in a fluid.
When valve opening:Under the action of the spring, valve element opens protective case and protects valve element, while in spring Under effect, spring base protects the inner cylinder face that valve element closes protective case, and liquid flows in the endoporus of spring base.
When the valve is closed:Valve element, which enters, to be leaned and moves forward with spring base in valve element closing protective case, is closed and is protected with valve element The inner circle formation sealing of sheath, fluid can not pass through, and realize valve closing.
Valve element in the utility model is all protected no matter when being turned on and off, and valve element can not be with fluid media (medium) Contact, has been reduced or avoided the existing valvular keying part exposed defect in fluid passage completely.This valve is being opened simultaneously When opening state, fluid media (medium) is flowed out from the endoporus of spring base, and impacts the end face of valve element, and opens protective case and valve from valve element The space flow direction outlet that core is closed between protective case, flowing washes away the end face of two protective cases and valve element, makes it that fouling is not present With fouling occupy-place problem.The utility model leaves valve element according to valve element and opens the distance of protective case to adjust uninterrupted, flow With apart from linear, flexibility and reliability.The utility model substantially prolongs the service life of Liquid valve, save frequently more The expense of valve is changed, the indirect loss caused by valve is damaged is reduced, while decreasing the worry of user.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
