Valve body is circular and charging and discharging ports are set in the middle parts of the upper and lower surface of valve body respectively meanwhile there are ports for vacuum-pumping at the left and right side of the valve body. Two ends of cylinder body are fixed with cover respectively and valve shaft of valve core rotor is supported by bearing on the cover. Valve core rotor comprises valve shaft, center plate, circular board, circular clamp, rubber ring, strip clamp, rubber board, screw, shim and mucilage glue. Center plate is respectively welded with valve shaft and circular board, which is welded with valve shaft. The rubber board is fixed to the top of center plate by screw, shim and strip clamp and rubber ring is bonded with rubber board by mucilage glue. The invention is provided with simple structure and good sealing performance.
Description
Affiliated technical field
The present invention is the equipment on a kind of agricultural products low temperature vacuum drier, or rather: be a kind of encapsulated rotary valve that is used for feeding and discharging.
Background technique
The rotary valve that is usually used in feeding and discharging on the agricultural products low temperature vacuum drier at present is a TGFZ type rotary valve, but it does not possess the performance of sealing, so when feeding and discharging, inevitably air is brought into the low temperature vacuum drier structure, is influenced the dry mass and the drying efficiency of material cryogenic vacuum.
Summary of the invention
For overcoming the defective that above-mentioned TGFZ type rotary valve does not possess sealability, the invention provides a kind of good airproof performance, encapsulated rotary valve simple in structure.
The technical solution adopted in the present invention is such: encapsulated rotary valve, it is mainly by valve body, cover plate and spool rotor are formed, valve body is a circular cylinder body, on the cylndrical surface, is respectively arranged with material feeding mouth and discharge port up and down therebetween, the left and right sides is provided with respectively and vacuumizes interface, the two ends of cylindrical shell are affixed with cover plate respectively, and the valve shaft of spool rotor is by the bearings that is arranged on the left and right cover plate, and the axle center of valve shaft should be identical with the axle center of valve body.Wherein the spool rotor mainly is made up of valve shaft, annular endplate, disc, annular pressing plate, rubber ring, viscose glue, I screw gasket, II screw gasket, strip plate, rubber strip; 6-10 piece disc vertically is distributed on the circumference of valve shaft and is affixed with valve shaft; Left and right two ends at disc are provided with annular endplate respectively, and annular endplate is affixed with valve shaft and disc respectively; The II screw gasket that on the ring-shaped step of annular endplate outside top end, rubber ring, annular pressing plate is set and is uniformly distributed along the circumference, and annular pressing plate and rubber ring are fixed tightly on the annular endplate by the II screw gasket, rubber ring is arranged between annular endplate and the annular pressing plate, utilize rubber ring external diameter end face to contact, closed cylinder gas flow channel vertically with valve interior surface; Rubber strip, strip plate are set and along the uniform I screw gasket of its length direction on the step of disc top end, and strip plate and rubber strip are fixed tightly on the disc by the I screw gasket, rubber strip is arranged between strip plate and the disc, utilize the top of rubber strip and contacting of valve body cylinder inner surface, closed cylinder gas flow channel radially; Rubber ring on the annular endplate and the rubber strip connecting part on the disc are bonding with viscose glue, to seal gap therebetween, prevent gas leakage.
Working procedure of the present invention is such: the material feeding mouth of material from valve body enters the spool rotor by in the hopper that disc and annular endplate constituted, rotation along with valve shaft, this hopper enters the inner chamber of valve body, this hopper then becomes sealing case, the sealing at annular endplate place, guarantee that by rubber ring the sealing at disc place just guarantees by rubber strip, when this hopper turns to when vacuumizing interface position, surplus air in the hopper is taken away by the vacuum external system, then, this hopper progressively goes to discharge port, and material just falls, so, in fill process, material feeding mouth does not communicate with discharge port is isolated, promptly advances, the air of discharge port can not be ganged up mutually.Therefore, useful meaning of the present invention just is, use it for the charging/discharging device of the low temperature vacuum drier of agricultural products, it just can be in the feeding and discharging process bring air into the drying oven that vacuumizes, thereby can produce continuously, can not influence the dry mass of material, and improve productivity greatly.
