Thrust valve
Technical field
The present invention relates to a kind of pipe switch valve, relate in particular to and a kind ofly in pipeline, control gas, liquid carries the valve of dust and dirt flow of matter.
Background technique
At present, pipeline valve is various in style, be widely used, but not only control air in pipeline, flow of fluid, and the valve that the control valve that carries gas, the flow of fluid of dust and dirt material carries the dust and dirt flow of matter not yet emerges, people thirst for a kind of in pipeline the valve of braking dirt media flow come into the market early.Development along with science and technology, pipeline has become the whole world to carry the artery of gas, liquid, the key of controlling ducted flowing medium motion is to set up valve, existing valve is of a great variety, mainly contains three kinds of ball valves, plate valve, butterfly valve, respectively has characteristics very distinct, but its fatal drawback is arranged all, ball valve rotates dumb, and plate valve need to rotate tens circles and could put in place by switch, and butterfly valve only adapts to the needs of controlling cryogenic medium flows.
Summary of the invention
The purpose of this invention is to provide a kind of tight-closed, braking simple and flexible and little, the lightweight valve of volume; Simultaneously the present invention uses material extensive, can select the material that adapts to flowing medium high and low temperature requirement in the pipeline to make, and improves the working life of valve, reduces maintenance rate.Dirt media flow in the valve energy brake-press lead of the present invention.
Technological scheme of the present invention is as follows:

Above-mentioned a kind of thrust valve, it is characterized in that: steering gear is straight-tooth, Knucle-gear form, the steering gear outside is the housing that supporting plate and gland form, supporting plate and gland are fixed by positioning rod, gland substantially horizontal both sides have shuttling holes, shuttling holes is built-in with straight-tooth, has adopted the feather key of guide-localization effect to cooperate between straight-tooth and steering gear housing; The Knucle-gear coaxial with brake axle is installed in the steering gear housing, Knucle-gear and straight-tooth engagement, the right-hand member of straight-tooth passes behind the taper valve plate center, outer spacing by pin, and straight-tooth right-hand member head is by seal cap sealing, and sealing cover is fixedly connected on the outer taper valve plate.
Above-mentioned a kind of thrust valve is characterized in that: being vertically fixed with roller and Knucle-gear in the steering gear housing, that straight-tooth is carried out clamping is spacing; Positioning rod is designed with adjusting nut in the support positioning plates both sides.
Above-mentioned a kind of thrust valve, it is characterized in that: steering gear is the worm and gear form, the steering gear outside is the housing that supporting plate and gland form, supporting plate and gland are fixed by positioning rod, gland substantially horizontal both sides have shuttling holes, level is equipped with cylindrical gears in the shuttling holes, the helical gear coaxial with brake axle is installed in the steering gear housing, helical gear and cylindrical gears engagement, the right-hand member of cylindrical gears passes taper valve plate center, outer and is fixedly connected with it, cylindrical gears right-hand member head is by seal cap sealing, and sealing cover is fixedly connected on the outer taper valve plate.
Above-mentioned a kind of thrust valve is characterized in that: positioning rod is designed with adjusting nut in the support positioning plates both sides.
Above-mentioned a kind of thrust valve is characterized in that: be designed with the scrubbing tooth of taper in the outer rim border of outer mitre velve plate outside wall, the scrubbing tooth outside is in same plane with the inclined-plane, outer of outer taper valve plate.
Advantage of the present invention is as follows:
1, in this thrust valve valve casing through be in the pipeline through one times of sectional area, media flow is unobstructed in the valve.
2, at outer mitre velve plate and interior along on the basis that wide-mouth flange spigot and socket type cooperates, the precession of helical gear interlock cylindrical gears has guaranteed that the scrubbing tooth on the outer taper valve plate is removed with interior along the dirt on the wide-mouth flange conical surface, and both sides contact closely knit.
3, after the open and close of this thrust valve, the turn braking device has guaranteed that valve plate location do not rebound, and has guaranteed the sealing effect of valve.
4, this thrust valve is widely used, and especially adapts to big-and-middle-sized dirt-carrying gas-liquid pipeline braking.
5, this thrust valve valve body is little, lightweight, valve casing generally be straight-run of pipe weight, add the quality of two flanges and the relevant widgets such as spool.
6, this thrust valve can be selected the unlike material manufacturing according to the high and low temperature medium that flows in the pipeline, and material selection is extensive, and temperature tolerance is high, long service life.
7, the fixing silk that all adopts of each build-up member connects, and is convenient to the field-strip maintenance.
