Description
Technical field
The present invention relates to a kind of safety interlocking 2/2-way stop valve, specifically a kind of safety interlocking soft seal 2/2-way stop valve, belongs to mechanical manufacturing field.
Background technique
Stop valve is a kind of general air pressure valve that uses, and its open-shut device is the valve block of stopper, and sealing surface is plane or the conical surface, relies on valve thick stick pressure, and valve clack sealing surface and sealing surface of seat are fitted tightly, and stops medium circulation.Now widely used 2/2-way stop valve adopts metal and ceramic seal more, opens and closes over hundreds of and just there will be poorly sealed phenomenon later.What EMU safety interlocking adopted at present is 2/2-way stopcock, is a kind of of stop valve, and its effect is cut-off and connects gas circuit, is arranged in EMU safety interlocking key locker.The cock body of stopcock mostly is cone, with the conical bore face mix proportion sealing pair of valve body, is a kind of valve using the earliest, simple in structure, switch is rapid, fluid resistance is little, by accurately machined metal cock body, seal with direct contact the between metal valve body, so sealing is poor, and complex process, poor air-tightness, mechanical life, number of times was short, and hoisting capacity is large, easily wearing and tearing, operational stability is poor, has potential safety hazard.
Summary of the invention
The object of the invention is to solve the existing defect of stopcock, and a kind of safe and reliable, compact structure is disclosed, maintenance operation is easy, tightness good, the safety interlocking soft seal 2/2-way stop valve that mechanical life is long.
The technical solution adopted in the present invention is: take valve seat as benchmark piece, the structure of valve seat is circle or ellipse or rectangle or irregularly shaped, inlet hole and air outlet hole are set on valve seat, at inlet hole, Sealing is set respectively in air outlet hole, Sealing and valve seat inlet hole, air outlet hole coordinates closely assurance periphery to seal completely, on Sealing top, valve block is set, at valve block, the place, joint clearance of valve seat and Sealing arranges supplemental support pad, inlet hole is set on valve block, air outlet hole and pressurized hole, the central position of valve block arranges rotating shaft, between rotating shaft and valve block, pressurized spring is set, valve gap is set on valve seat, between valve gap and valve seat, be provided with valve bonnet seal circle, rotating shaft via seal circle is set on valve gap, setting operation handle in rotating shaft, the structure of operating grip is circle or ellipse or rectangle or irregularly shaped, valve gap is fixedly connected with valve seat, two position limit pins are set on valve gap, limiting stopper and square groove are set on operating grip.
The present invention adopts metal and nonmetallic plane soft sealing structure, nonmetallic material adopt abrasive rubber, Sealing is set and can guarantees to reduce area of contact, the stationarity that supplemental support pad can guarantee motion is set, this structure fabrication technique is simpler, and tightness is good, can reach several ten thousand above nothings mechanical life and leak, safety reliability is strong, can on rail motor set and other high speed motion, use.
