The position of diameter may make the sealing ring of different-diameter that can be fixed on the end face of disk, closed guard gate's valve energy of different-diameter
It is fixed on sealing ring, sealing ring may make the better tightness between closed guard gate's valve disk, avoid gas leakage to the external world
In environment, the test of closed guard gate's valve air-tightness is influenced.
Further, the fixed device includes bolts and nuts, and the bolt passes through the second aperture and the from disk side
One aperture and the end face for deviating from disk beyond sealing ring, the nut connect from sealing ring away from the side of disk and bolt thread
It connects.
Implement above-mentioned technical proposal, bolt passes through the second aperture and the first aperture, sealing ring is mounted on bolt, then is worn
The mounting hole on people's air defense gate valve door is crossed, nut is finally mounted on the one end of bolt beyond sealing ring away from disk end face, so that
Sealing ring is fixed between disk and closed guard gate's valve, and closed guard gate is fixed on sealing ring.
Further, the sealing ring is rubber seal.
Implement above-mentioned technical proposal, the airtightness in the space that rubber seal can be such that disk and closed guard gate's valve constitutes is more
It is good, it avoids gas leakage into outside air, the situation of gas air tightness test inaccuracy is caused to occur.
Further, the cross-sectional of the air inlet is greater than the cross-sectional of air outlet.
Implement above-mentioned technical proposal, when the air-out flow of air outlet be less than air inlet air inlet flow when, can make disk with
The space formed between closed guard gate's valve is in superpressure state, so that in the space formed into disk and closed guard gate's valve
Gas can be squeezed out outside air outlet.
Further, there are two symmetrical handle, the handle is parallel with disk for the side wall setting in the disc thickness direction.
Implement above-mentioned technical proposal, in the fixation procedure of disk and closed guard gate's valve, disk need to be moved, handle is set,
Staff can be made more convenient when moving disk.
Further, anti-skid chequer is provided on the handle.
The case where implementation above-mentioned technical proposal can avoid staff when moving disk, and disk slides occurs.
In conclusion the utility model has the following beneficial effects:
After closed guard gate's valve is aligned with sealing ring, bolt sequentially passes through the second aperture on disk, close from the side of disk
Sealing ring and closed guard gate's valve are all fixed on the side wall of disk by the mounting hole in the first aperture, closed guard gate's valve in seal
On, and corresponding with sealing ring fixed device is set on disk, may make the closed guard gate's valve and different-diameter of different-diameter
Sealing ring can be fixed on the end face of disk, and sealing ring then may make the better tightness between closed guard gate's valve disk, avoid
Gas leakage influences the test of gas air-tightness into external environment.
