Abstract
The utility model relates to a fast opening and closing sluice valve. A valve cap of the sluice valve composed of valve body with a valve seat, a valve rod, a sluice plate and a valve rod connected with the sluice plate is provided with an integrally connected a centering guiding sliding sleeve of the valve rod which is communicated with a cavity of a valve core, and the valve rod is integrally connected with a cog plate. The side wall surface of the centering guiding sliding sleeve of the valve rod is provided with box chamber and a gear box provided with a bearing and communicated with the centering guiding sliding sleeve of the valve rod, and a driving gear engaged with the cog plate of the valve rod is arranged in the gear box. One end of a wheel shaft of a gear wheel extended out of the gear box is the opening and closing operation end of the valve, and the wheel shaft of the gear wheel is sealed by a sealing element arranged in the bearing. The utility model has the characteristic of high speed for opening and closing the valve.
Description
Technical field
The utility model relates to a kind of gate valve.
Background technique
Gate valve is a kind of use control valve widely, is loaded on the control of carrying out mass transport on the various liquid material pipelines.The unlatching of existing gate valve, to close all be that screwed makes valve rod drive the valve flashboard lifting to realize, drives that flashboard rises or the distance of the pitch that descends because valve rod rotates all valve rods, so its unlatching, the speed of closing are very slow.For the use occasion that the ask for something valve is opened fast or closed, existing screwed opening type gate valve is difficult to adapt to and satisfy usage requirement.
Summary of the invention
But the purpose of this utility model provides a kind of gate valve that adapts to and satisfy valve opening, closes the fast opening and closing of rapid usage requirement.
The purpose of this utility model realizes by following design.
Valve gap by valve body, the valve gap of band valve seat, flashboard that is loaded on the valve body and valve seat place and the gate valve that constitutes with valve rod that flashboard connects has the whole valve rod centering pilot sliding sleeve that is connected, and valve rod stretches in the sliding sleeve.Integral body is connected with tooth plate on the valve rod, the gear-box that the tape spool letter that the case chamber is communicated with valve rod centering pilot sliding sleeve is arranged on the valve rod centering pilot sliding sleeve side wall surface, be loaded in the gear-box with the actuation gear of valve rod tooth plate engagement, it is the valve opening and closing operating end that gear hub is stretched out the outer end of gear-box, and gear hub is by the Sealing sealing that is loaded in the letter.
When but the gate valve of the fast opening and closing that the utility model provides uses, turn actuation gear wheel shaft operating end actuation gear drives valve rod and rises rapidly valve opening, oppositely turn actuation gear wheel shaft operating end actuation gear drives valve rod and descends general who has surrendered's valve closing rapidly, so gate valve opens and closes fast.
Description of drawings
But Fig. 1 is the structural drawing of the gate valve of fast opening and closing.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the B-B sectional view of Fig. 1.
Embodiment
But accompanying drawing is an embodiment of the gate valve of the utility model fast opening and closing, describes embodiment of the present utility model in detail below in conjunction with embodiment.
As shown in the figure, but the gate valve of fast opening and closing by the valve body (7) that is installed with valve seat (6) and adpting flange (5), (9), (10), have the wedge shape flashboard (8) of guide chute, spool guide slide (23) arranged on the valve interior wall face of gate valve that the valve rod (4) that flexibly connects with flashboard, the valve gap (12) that has adpting flange (11) constitute, flashboard is loaded on that guiding is sliding to be led.Valve gap has the whole valve rod centering pilot sliding sleeve (1) that connects.Valve rod has the whole tooth plate (2) that connects, and the valve rod that has tooth plate stretches in the guide sleeve, and valve rod can be slided up and down and feel relieved by the guide sleeve guiding.The gear-box that has a letter (15) (22) that has the case chamber to be communicated with on the stem guiding sliding sleeve side wall surface with guide sleeve, the actuation gear (21) that meshes with the valve rod tooth bar is loaded in the gear-box, and it is the operating end that gear hub (16) is stretched out the outer end of case by the axle letter.Handle (20) is equipped with in the operating end, and operating grip is locked on wheel shaft by bolt (17).The seal ring (14) and the stuffing box packing (18) that are sleeved on the gear shaft are loaded in the gearbox shaft letter, compress and prevent the gear shaft axial float and gear shaft is sealed by screwing the gland (13) that is fastened on the letter.Valve gap is connected and fixed on valve body by clamping bolt (3), and interface is sealed by sealing gasket (19).
But the gate valve of the fast opening and closing that the utility model provides is installed joint pipe structure except that illustrated valve flange connection structure, can make screw connection structure or to welding structure, flashboard can be made into the flashboard of parallel type flashboard, wedge shape flashboard or other patterns according to usage requirement.The wedge shape flashboard can be the rigidity flashboard and also can be Flexible disc.
Claims (1)
1, a kind of gate valve of fast opening and closing, valve body by the band valve seat, valve gap, the valve rod that is loaded on the flashboard at valve body and valve seat place and connects with flashboard constitutes, it is characterized in that valve gap has the whole valve rod centering pilot sliding sleeve that connects, valve rod stretches in the sliding sleeve, integral body is connected with tooth plate on the valve rod, the gear-box that the tape spool letter that the case chamber is communicated with valve rod centering pilot sliding sleeve is arranged on the valve rod centering pilot sliding sleeve side wall surface, be loaded in the gear-box with the actuation gear of valve rod tooth plate engagement, it is the valve opening and closing operating end that gear hub is stretched out the outer end of gear-box, and gear hub is by the Sealing sealing that is loaded in the letter.
