The flat end of above-mentioned stainless steel elastic packing reed withstands on the shaft shoulder bracket base, and cambered top end is against blade edge portion.
Above-mentioned stainless steel elastic packing reed is U-shaped, basin shape sheet or pie-shaped piece.
Be connected by the universal joint shaft clamp between above-mentioned valve body and the executing agency, the going up of this universal joint shaft clamp connects clamp and is connected following connection clamp connection stainless steel driving shaft with connecting axle.
Fastening between the connecting axle of above-mentioned universal joint shaft clamp and the mechanism's main shaft by the recessed end holding screw of hexagonal in the high rigidity.
Beneficial effect: this closed is manually split the advantage of leafy control valve: 1, because of the blade periphery is provided with silica gel sealing bar, stainless steel elastic packing reed, valve has excellent sealing ability, and the valve leak amount is very little.2, the aging back of the silica gel sealing bar of blade periphery setting is changed easily.3, because of using stainless steel driving shaft, stainless steel blade axle, brass axle sleeve, valve to have long-term service life, do not need multipurpose lubricant.4, blade is split linkage and is arranged on valve inner, and the user can select the four sides insulation as required or not be incubated.Therefore need not consider when making to be incubated, the difference of non-insulation, made things convenient for management, reduced the plant produced cost simultaneously.5, adopt the universal joint shaft clamp because of executing agency adopts handwheel rotational structure, mechanism to be connected with valve body, the valve blade is opened, and closes brisk, flexible, fluent.6, because of the connecting axle of recessed end holding screw fastening executing agency main shaft of hexagonal and universal joint shaft clamp in the employing high rigidity, bearing capacity is big, valve blade unlatching, unshift when closing, and the blade opening angle is constant all the time.7, because of adopting the novel linkage of splitting, when opening, can split synchronously in blade.8, screw drive is adopted in executing agency's action, and blade has auto-lock function after opening.9, because of executing agency top the conveniently adjusted blade opening angle of angle indicator position is set.
