Abstract
The utility model relates to a novel gate valve in the field of high-pressure gate valves, which comprises a valve body, flanges on both sides of the valve body, a valve core in the valve body and a valve core control mechanism, wherein the valve core in the valve body is a large semi-circular flashboard having a radius larger than the diameter of the port of the flange; the axis of the flashboard is fixed in the valve body through a fixed shaft; a circular inner cavity hermetically matched with the flashboard in a rotatable manner is arranged in the cavity body; the port of the flange is communicated with the circular inner cavity in the valve body; tooth slots are arranged at the periphery of the flashboard; small gears are matched with the tooth slots and are hermetically fixed on the valve body through a gear box; and a crank handle is inserted on the rotation shaft of the small gears. By adopting the control manner of a large-aperture rotary flashboard, the gate valve can greatly improve the work torsional force, thereby achieving more convenient and flexible operation and control of the gate valve and improving the sealing reliability of the gate. The use of the special crank handle can improve the antitheft safety of the gate valve.
Description
Technical field
The utility model relates to a kind of novel gate valve in the high pressure sluice valve field.
Background technique
Present high pressure sluice valve mainly is that flashboard is set in the valve body, flashboard by valve body top hand take turns with bolt rod driving spool (flashboard) in the body cavity lifting, control unlatching (or closing) degree of flashboard and latus rectum with this, realize the corrective action of valve.This class gate valve is subjected to the influence of frictional resistance in manifold pressure height and the screw rod lifting process in actual applications, and gate valve operates and requires great effort very much, and is difficult to reach the requirement of high pressure sealing.
The model utility content
The purpose of this utility model is exactly the defective that exists at prior art, and the novel gate valve that a kind of flexible operation is light, high pressure sealing performance is good is provided.
Its technological scheme is: comprise the flange of valve body, valve body both sides, spool and the spool control mechanism in the valve body, spool in the valve body is the large semi-circular flashboard of radius greater than flange latus rectum diameter, the axle center of flashboard is fixed in the valve body by stationary axle, be provided with the round cavity that cooperates with flashboard rotary seal in the valve body, round cavity in the latus rectum of flange and the valve body connects, outer periphery at flashboard is provided with teeth groove, the teeth groove fit on has small gear, small gear on valve body, is plugged with wind in the rotating shaft of small gear by the gearcase sealing and fixing.
In order to prevent the corrosion of valve inner, on flashboard and involutory surface that inner chamber rotary seal cooperates, be respectively equipped with ceramic layer.
The utility model can greatly improve work torsion by bigbore rotary flashboard control mode, thereby makes controlling of gate valve lighter, more flexible, has improved the sealing reliability of gate simultaneously.Cooperate special-purpose wind, can improve the anti-theft security of gate valve.The ceramic coating that increases can improve its rust resistance, thus whole the raising working life.
Description of drawings
Accompanying drawing 1 is the schematic appearance of gate valve, and Fig. 2 is the A-A sectional view among Fig. 1.
Embodiment:
Contrast accompanying drawing 1, valve body comprises 4 whole compositions of main valve body 3 and latus rectum valve body, and the both sides of latus rectum valve body 4 are respectively equipped with flange 5, in the upper outside sealing and fixing of main valve body 3 gearcase 1 is arranged, small gear in wind 2 and the gearcase 1 is pegged graft and is cooperated, and rocks from side to side to realize the open and close of valve.Contrast accompanying drawing 2, the below in the main valve body 3 is a latus rectum 11, is fixed with the flashboard 9 (or claiming spool) in more than half garden on the main valve body 3 on latus rectum top by rotating shaft 10, the radius of flashboard 9 is greater than the diameter of latus rectum 11.Be shaped on circular flat groove (cavity) in the main valve body 3 in advance, flashboard 9 rotates in the flat groove of circle and latus rectum 11 is sealed and matched, with the adjustment that realizes that gate valve is opened or closed.The outer periphery of flashboard 9 is provided with teeth groove 8, and teeth groove 8 cooperates with small gear 6 in being fixed on main valve body 3 upper gear boxes 1, and the central shaft 7 of small gear 6 cooperates with the grafting of the connection-peg of wind 2.On the mating face of flashboard 9 and circular flat groove, be equipped with ceramic layer, to improve its wear resistance and rust resistance.
During use, as long as with the wind left-right rotation, flashboard is pressed the direction initialization rotation, adjusts the unlatching of latus rectum or closes degree with this, realizes the adjusting of flow.
Claims (2)
1, a kind of novel gate valve, comprise the flange of valve body, valve body both sides, spool and the spool control mechanism in the valve body, it is characterized in that: the spool in the valve body is the large semi-circular flashboard of radius greater than flange latus rectum diameter, the axle center of flashboard is fixed in the valve body by stationary axle, be provided with the round cavity that cooperates with flashboard rotary seal in the valve body, round cavity in the latus rectum of flange and the valve body connects, outer periphery at flashboard is provided with teeth groove, the teeth groove fit on has small gear, small gear on valve body, is plugged with wind in the rotating shaft of small gear by the gearcase sealing and fixing.
2, novel gate valve according to claim 1 is characterized in that: be respectively equipped with ceramic layer on flashboard and involutory surface that inner chamber rotary seal cooperates.
