Abstract
The invention relates to a plug valve, in particular to a full-sealing zero leakage plug valve. A valve rod is driven by an arc driving connecting rod; a valve cover is wholly box-shaped and wraps the valve rod and the arc driving connecting rod; a metal corrugated pipe is arranged between the end of the arc driving connecting rod and the valve cover; therefore, high sealing property is achieved; meanwhile, the plug valve keeps the advantage that the conventional plug valve can be opened and closed when rotated 90 degrees.
Description
Technical field
The present invention relates to a kind of stopcock, particularly the full-seal zero-leakage stopcock.
Background technique
The invention of valve attends by human life with application always closely, produces and work, also the history in thousands of years has been arranged so far.Because the continuous increase of demand, the kind of valve, specification output are constantly increased sharply, and according to incompletely statistics, China has more than 3,000 kind of about 30,000 plurality of specifications of valve at present.Valve is the important device of transporting fluid, particularly in inflammable, explosive, the poisonous and hazardous danger medium of transporting, to the sealing of safe and reliable consideration to valve, intensity assurance property has proposed strict requirement.Stopcock since have handle only turn 90 degrees just can realize opening and closing, operate save time, laborsaving, the reliable advantage of sealing and being widely used.Present stopcock valve gap is connected with bolt, nut with valve body and forms sealing.Yet this Seal cage has two leak sources, and one is the joint of valve gap and valve body, and another place is that valve rod rotates at the stuffing box place and produced matching gap too, for preventing to leak, have to be clipped in the place, slit with sealing gasket and go to block up.When the transporting medium temperature raises, the pressure increase makes that the working environment of valve is very harsh, in order to guarantee being perfectly safe of transporting hazmat, the most basic way is cancelled this two leak sources exactly.Reach the opening and closing valve for those open-shut device by lifting valve pocket inside, as stop valve, gate valve etc., people can be by being provided with the hanger of open-shut device in the valve rod lower end, the hanger Spielpassung is arranged in the valve pocket, between the valve port of valve body and hanger, be provided with corrugated tube shape elastic telescopic spare, described elastic telescopic spare two ends separate flashboard and upper cover with valve port and hanger fixed seal connection respectively, thereby reach the purpose of full-seal zero-leakage.Stopcock is a kind of common valve, but the medium of both transporting liquid state of stopcock, gaseous state, solid-state a single state, medium that again can the liquid-solid mixing shape of transporting, and stopcock has handle and only turn 90 degrees the advantage that just can open and close, open quick, save time, laborsaving sealing is reliable, using scope is extensive.But reach the opening and closing valve by 90 degree rotation faucet bodies for stopcock is this, because bellows can't be done radially rotational deformation, said structure can't be suitable for, need to become straight line motion with rotation, straight line motion becomes the mechanical shifting mechanism that rotatablely moves again, make the structure more complicated, and overall dimensions uprises.
Summary of the invention
The objective of the invention is to provides a kind of stopcock of seamless full-seal zero-leakage for overcoming the deficiencies in the prior art.
In order to achieve the above object, technical solution provided by the invention is: a kind of full-seal zero-leakage stopcock, include valve gap, valve body, faucet body and valve rod, it is characterized in that: described full-seal zero-leakage stopcock is provided with at least the arc drive link greater than 90 degree arc length, described arc drive link one end is fixedlyed connected with valve rod by joint radially, described valve gap integral body is the case shape valve rod and arc drive link is wrapped in wherein, described bonnet lower is connected with valve seal, the position corresponding with the arc drive link is provided with its rotatable space that is not less than 90 degree of confession that matches with described arc drive link on the valve gap, described space relative with the described arc drive link the other end radial sidewalls be provided with tie rod holes, this end end of described arc drive link passes from tie rod holes, the described part arc drive link that passes from tie rod holes is arranged with metal bellows, described metal bellows one end and tie rod holes are tightly connected, and the other end is enclosed in tie rod holes wherein and is connected with valve bonnet seal.
Compared with prior art, the invention has the beneficial effects as follows: the present invention is by arc drive link actuate valve stem, valve gap integral body is the case shape valve rod and arc drive link is wrapped in wherein, and between the end of described arc drive link and valve gap, be provided with described metal bellows, reach good sealing, also kept traditional stopcock only to turn 90 degrees the advantage that just can open and close simultaneously.
The invention will be further described below in conjunction with the drawings and specific embodiments.
