Described oscillating bar crank isolating valve, drive device action drives crank to be swung around crank axle with lever, and the swing rod that drive is connected with lever hinge swings and lifted, and drives swung and elevated, valve opening with the hinged flashboard of swing rod therewith；Drive device backhaul, valve closing；
Crank cut-off valve fluid pressure drive device drives crank and lever drive, so that band driven fork swings and lifted, drives flashboard to swing and elevated therewith, realizes the breakdown action of flashboard；Fluid pressure drive device backhaul, flashboard is to be closed, and pipeline medium is cut off.
Beneficial effects of the present invention：
The present invention
The high-temperature behavior after valve sealing surface build-up welding is improve, is solved
137
It is larger that number bond flux overlay cladding has during high temperature that hardness declines, and improves overlay cladding high temperature hardness conservation rate, improves high-temperature behavior.
Physical dimension of the present invention is small, lightweight, flashboard has certain rotating folding process in valve opening and turn-off transient with respect to valve body, it is to avoid the generation of original flashboard voussoir stuck phenomenon, and valve switch reliable in action can for a long time ensure the sealing property of sealing surface.

Oscillating bar crank isolating valve described in embodiment 1,
Sealing pair includes rams contact face and valve body contact face, is the valve core position, directly affects valve seal performance and life-span.According to the working condition of the valve, it is desirable to which contact surface will have certain hardness, thermohardening, wearability and resistance to gas erosion.Therefore, selection to adapt to operating mode cost performance higher
D507MoNb
, built-up welding treatment is carried out to sealing pair.In opening, valve rod dextrorotation, guide pad guiding valve rod drives valve plate to right rotation
90°
, sealing surface of valve plate is in parallel position with valve body sealing surface, valve rod continues dextrorotation, and guide pad guiding valve rod is moved downward, and promotes upper and lower voussoir, makes voussoir wedge surface promote valve plate and valve body sealing surface to contact, and butterfly valve is closed, and realizes sealing；In off position, valve rod is left-handed, guide pad guiding valve rod is moved up, upper and lower voussoir is promoted to make motion upwards, voussoir wedge surface drives valve plate translation, and sealing surface of valve plate and valve body sealing surface depart from, after valve plate moves certain eccentric distance, valve rod continues left-handed, guide pad guiding valve rod rotation, and drives valve plate to anticlockwise
90°
, butterfly valve unlatching.Discord valve body sealing surface produces interference when being opened and closed relative to rotation after valve body sealing surface skew certain distance, therefore valve plate due to valve plate.
The thrust of the wedge that valve rod upper and lower parts are set can overcome the pressure of medium reverse flow, make butterfly valve that reliable sealing is realized under the operating mode of medium two-way flow.Wedge form wedge form dovetail groove is provided with valve plate, valve rod does upper and lower motion and drives wedge motion, wedge displacement to apply sealing force to sealing surface of valve plate, improve the sealing property of butterfly valve, while can compensate for the abrasion of sealing pair, improves metallic seal butterfly valve reliability.The wedge surface of wedge promotes valve plate to do reciprocating linear motion in valve plate wedge form wedge form dovetail groove, valve plate is contacted or depart from valve body sealing surface, reduces the scratch of sealing surface.Valve plate first moves along a straight line, then rotary motion, extends the opening and closing time of butterfly valve, reduces the hydrodynamic moment of butterfly valve.Sealing surface of valve plate and valve body sealing surface are the conical surface, and sealed reliable, design and processing are simple.
