Abstract
The utility model discloses a rotating seal valve device which comprises a valve body (2), a rotor (1) and a gland (11). A groove is formed in the inlet end of the valve body (2), and a spring (3), a check ring (4) and a sealing ring (6) are sequentially arranged in the groove. The gland (11) is fixed on the valve body (2) through a screw (10), two single-row centripetal bearings (9) and a baffle ring (8) are arranged in the gland (11), and the baffle ring (8) is arranged between the two single-row centripetal bearings. The rotor (1) is placed in the valve body (2) and rotates around the valve body (2) through the two single-row centripetal bearings (9), one end of the rotor (1) is connected with the sealing ring (6), and the other end of the rotor (1) is connected with the rotating end of the valve body (2). The rotating seal valve device can be used in a pneumatic clutch, and is good in sealing performance and long in service life.
Description
Technical field
The utility model relates to a kind of rotary seal control valve unit.
Technical background
On pneumatic clutch, by inflating in capsule, and the holding tightly of brake shoe that completes clutch, but pneumatic clutch will ceaselessly rotate, guarantee that again the gas pressure in capsule is constant, the state of holding tightly of guarantee brake shoe like this, clutch could work, so need to design a kind of rotary seal control valve unit, realize to the object of the clutch inflation of rotating.
Summary of the invention
The utility model provides a kind of rotary seal control valve unit, can be for pneumatic clutch, and sealing valve seal performance is good, long service life.
The utility model has adopted following technological scheme: a kind of rotary seal control valve unit, comprise valve body, rotor and gland, the two ends of valve body are respectively entrance point and rotate end, and two ends are sealing configuration, entrance point at valve body is provided with notch, is provided with successively spring, back-up ring and seal ring in notch; Described gland is fixed by screws on valve body, is provided with two single-row centripetal bearings and baffle ring in gland, and described baffle ring is arranged between two single-row centripetal bearings; Described rotor is positioned at valve body and rotates around valve body by two single-row centripetal bearings, and the seal ring of one end of described rotor and valve body entrance point is connected to form sealing pair structure, and the other end is connected with the rotation end of valve body.
The inlet of described valve body is provided with O-ring seals; Between described back-up ring and seal ring, be provided with O-ring seals; On described valve body, be provided with plug screw with baffle ring corresponding part.
The utlity model has following beneficial effect: the utility model has solved a difficult problem for pneumatic clutch transmission gas, also there is good seal performance simultaneously, the advantage of long service life, rotor and valve body entrance point seal ring form sealing pair structure, reached can rotary seal effect.
