Description

Check-valves
Technical field
The present invention relates to a kind of check-valves.
Background technology
Check-valves is the element commonly used in pneumatic controlled hydraulic, in chemical field, equipment is caused in order to prevent liquid from flowing back Injury, and sucking pump will keep inlet ductwork to have liquid in working order, generally use various check-valves.Traditional non-return Valve is divided into three kinds of swing check valve, butterfly swing check valve and lift check valve, wherein swing check valve and butterfly swing check valve Though being straight-through type valve, because its structure is limited, it is only suitable for the severe corrosives such as metal material manufacture, resistance to hydrochloric acid, nitric acid, sulfuric acid and is situated between Matter is poor, and liquid still suffers from gravity and resistance from valve in flowing, and the whole forward direction process of circulation simultaneously has some setbacks Reduce operating efficiency;Although lift check valve can be manufactured using Fluorine-lined technique, liquid needs to promote pressure when opening Spring, motion angle of turn are big, and liquid easily produces vortex, and valve resistance is big, and flow, headloss are more serious, and sealing Effect is bad.
The content of the invention
Object of the present invention is to provide it is a kind of be able to bear strong corrosion, flow of media is smooth and non-return of good sealing effect Valve.
To achieve these goals, the present invention provides following technical scheme:A kind of check-valves, including valve body and valve element, institute Fluorine matter liner, large and small caliber section runner of the flow passage chamber including the arrangement that postpones, in face of feed liquor direction are attached on the valve interior wall stated The leading portion of valve element be the head of conical surface shape, the conical surface shape region of head constitutes with the varying diameter portion of large and small caliber section runner and contacts Non-return separates two kinds of mated conditions of water conservancy diversion, the diameter of the back segment diameter less than Large Diameter Pipeline section runner of valve element, the back segment week of valve element Circumferential arranged for interval has wing plate on face, is constituted along the mobile cooperation in runner direction between edges of boards and Large Diameter Pipeline the section runner of wing plate.
In above-mentioned technical proposal, valve body inner flow passage chamber be postpone arrangement large and small caliber section runner, be easy in valve interior wall On set up fluorine matter liner so as to corrosion resistance is extremely strong, the varying diameter portion of the head of valve element and large and small caliber section runner is constituted and contacts close Envelope separates two kinds of mated conditions of conducting, the diameter of the back segment diameter less than Large Diameter Pipeline section runner of valve element, is easy to after valve element Circumferential arranged for interval wing plate on section side face, during non-return state, valve element constitutes sealing and coordinates returning so as to barrier liquid with varying diameter portion Stream;During water conservancy diversion state, constituted along the mobile cooperation in runner direction between edges of boards and Large Diameter Pipeline the section runner of wing plate, valve element is in liquid Promotion under to being slid in Large Diameter Pipeline section runner, the head of valve element is with reduced diameter portion from interval and the stream of the wing plate being evenly arranged Form runner passageway between road chamber, the leading portion of valve element can reduce flow resistance for the head of conical surface shape, it is ensured that liquid is carried out Smoothly water conservancy diversion;After water conservancy diversion is finished, withdrawing fluid promotes valve element sliding to return to varying diameter portion, continues composition sealing and cooperatively forms only The state of returning.
