3/ h, only 78 milliseconds of the times of the complete switch of sentinel valve, and have good mechanical rotation performance and sealability.
In order to realize this purpose, the technological scheme that the present invention takes is: a kind of Novel pulse valve mainly is comprised of retarder, connecting sleeve, stuffing box bearing gland, valve body, mutual row's mouth, gland, bearing gland, suction port, stator, rotor and coupling; Wherein, valve body is cylindrical structure, and the lower end of valve body is fixed on valve seat by bolt, nut and pad; Top at valve body is equipped with retarder, and retarder is connected with valve body by connecting sleeve; The top of connecting sleeve is fixed with screw, packing ring and retarder, and the lower end is fixed with screw, packing ring and valve body top; Retarder is connected with the rotor of valve inner by coupling, and the retarder rotor driven rotates; At two ends, up and down, the rotor outside, one bearing is arranged respectively, rotor is connected rotation with stator by bearing, and stator is fixed by screw, pad and valve body; Use the stuffing box bearing gland seal between connecting sleeve lower end and rotor upper end, the rotor lower end seals with bearing gland, valve body be gland bottom, gland is by hold-down bolt sealed valve body lower end; A side at valve body arranges suction port, and suction port is connected with suction tude by bolt, pad, nut, flange; Mutual row's mouth is set on the opposite of suction port, and row's mouth is connected with mutual comb by bolt, pad, nut, flange mutually.
Further, a kind of Novel pulse valve as above, the valve body height is 624mm, diameter is 360mm; Connecting sleeve is round table-like structure, and the upper-end surface diameter is 80mm, and the lower end surface diameter is 226mm, is highly 235mm.
Further, a kind of Novel pulse valve as above, the height of rotor is 540mm, and internal diameter is 200mm, and wall thickness is 30mm; The height of stator is 540mm, and internal diameter is 280mm, and wall thickness is 20mm.
Further, a kind of Novel pulse valve as above, suction port are that diameter is the circle of 108mm, and row's mouth is that diameter is the circle of 219mm mutually.
Further, a kind of Novel pulse valve as above, the rotational speed of rotor is 60～120rpm.
The utility model sentinel valve shows that through test run air inflow can reach 2000Nm
3/ h, total air leakage is less than 30%, only 78 milliseconds of the times of the complete switch of sentinel valve.The development in China's nuclear fuel purification technique or even China's nuclear fuel cycle field is promoted play promoting effect, also the civilian industries such as pharmaceuticals industry, petrochemical industry, wet-process metallurgy are played the effect that expands the scale of production, increases economic efficiency, strengthens technical merit.
