Description
Technical field
The utility model relates to a kind of safety interlocking 2/2-way stop valve, and 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, and switching exceedes hundreds of and just there will be poorly sealed phenomenon later.What EMU safety interlocking adopted at present is 2/2-way stopcock, is the one 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, seal with direct contact the between metal valve body by accurately machined metal cock 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.
Model utility content
The purpose of this utility model is to solve stopcock existing defect, and open a kind of safe and reliable, compact structure, maintenance operation is easy, tightness good, the safety interlocking soft seal 2/2-way stop valve that mechanical life is long.
The technological scheme that the utility model adopts is:
Taking 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 guarantee periphery to seal completely, on Sealing top, valve block is set, at valve block, the joint clearance place 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 utility model adopts metal and nonmetallic plane soft sealing structure, nonmetallic material adopt abrasive rubber, Sealing is set and can ensures to reduce area of contact, the stationarity that supplemental support pad can ensure motion is set, this structure fabrication technique is simpler, and tightness is good, can reach mechanical life more than several ten thousand times without leaking, safety reliability is strong, can on rail motor set and other high speed motion, use.
