Description
Technical field
the utility model relates to cut-off throttle valve field, is specifically related to a kind of manual forging of bellows without spin welding end cut-off throttle valve.
Background technique
The throttle valve of current domestic employing all also exists the shortcomings such as high, the easy leakage of manufacture requirements, working life is short.Bellows cut-off throttle valve long service life, maintenance frequency is few, reduces operating cost.Robust sylphon seal design, ensures the zero leakage of valve rod, provides the condition of Maintenance free.Valve opening and closing moment is little, reduces labor intensity.Aesthetic in appearance, valve passage has smooth streamline, and reducing the flow resistance coefficient of valve, is a kind of high-quality energy-conserving product.The external sealed of valve adopts sylphon seal and graphite, stainless steel gasket to seal, and sealing is reliable, and permanent use can change stuffing box packing.Design and manufacture strictly adopts foreign advanced standard.F316 steel welding performance is poor, easily occurs crackle during sealing surface welding STL cemented carbide.
Summary of the invention
In order to solve the problem, the utility model proposes a kind of nuclear island Y shape and adding pipe arrangement High Temperature High Pressure pressure-relief type Double-clack stop valve, simplicity of design, easy to use, solving the valve short technical problem with improving valve serviceability temperature in working life, meeting applying working condition.
In order to reach foregoing invention object, the utility model proposes following technological scheme:
Manually bellows forges welding end cut-off throttle valve without spin, and it comprises valve body, poppet shaft, bellows, valve gap, Packing seat, filler, plane bearing, bearing gland, hold-down grid, guide plate, support, Stem Mut, handwheel, valve body intervening valve mandrel, bellows-sheathed outside in the middle of poppet shaft is housed inside valve body upper end, and valve gap is housed in valve body upper end and valve gap is fixed on valve body upper end by screw bolt and nut, successively Packing seat is housed from bottom to top in the middle of valve gap and between poppet shaft, filler, hold-down grid and hold-down grid is fixed on valve gap by swing bolt and nut, swing bolt lower end is connected on valve gap by straight pin, valve gap is equipped with support outside upper end, in the middle of support, guide plate is housed, aperture direction board is equipped with in guide plate side, pedestal upper end is equipped with Stem Mut, respectively bearing is housed between Stem Mut upper-lower position and support, bearing gland is stamped above the bearing of upper end, bearing gland is fixed on pedestal upper end by Cock screw, poppet shaft upper end is contained in the middle of Stem Mut, handwheel is housed on poppet shaft top and handwheel upper end is fixed by locking nut, by key location and installation between handwheel and poppet shaft, the sealing surface between poppet shaft lower end and valve body is that hard alloy overlay welding is formed.
The serviceability temperature of the described manual forging of bellows without spin welding end cut-off throttle valve is 600 degree.
The use pressure of the described manual forging of bellows without spin welding end cut-off throttle valve is 1500LB.
Described valve rod adopts fine pitch screw-driven.
The utility model has the advantages that structure is different: former valve rod separates with flap, is now integral valve mandrel; Serviceability temperature: former less than 350 degree, is now 600 degree; Use pressure: former below 600LB is now 1500LB; Valve rod adopts fine pitch screw-driven, can realize regulating the trace of flow; Former throttle valve stem rotary valve rod nut non rotating, now changes into without spin, valve rod non rotating, and Stem Mut rotates.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
