Abstract
The utility model discloses a separating lubricated valve. The valve rod of the valve and a threaded portion are separated by a rubber corrugated pipe; the threaded portion is provided with an oil groove and an oil seal containing oil; an oil hole is arranged on a valve cap. A valve which adopts the principle of the utility model has the advantages of long service life, and no leakage.
Description
The utility model belongs to a kind of valve in the engineering part.
Generally there is following problems as shown in Figure 2 in valve type of the prior art:
1. the sealing of valve rod and valve body all relies on filler, often causes leakage because of the wearing and tearing of filler position in the use.
The helical thread portion that combines with valve body of its valve rod since not lubricated and often effect of attrition its mechanical life.
3. the liquid that flows through in the valve can enter helical thread portion, and impurity and oxious component can quicken screw thread and partly damage therebetween.There is the bellows of use to do seal element in the prior art, but also has second problem.
It is isolated with helical thread portion and fluid section with the rubber helical pipe that the utility model purpose is to provide, and employing has the screw-thread fit of the nut and the valve rod of oil groove, install a kind of isolated lubricating type valve of oil sealing to guarantee that helical thread portion is lubricated of oil-containing additional in the periphery of nut, valve has long service life, fluid isolation in its oiling agent and the valve, do not have leakage phenomenon, be applicable to various stop valves, gate valve.Embodiment with a kind of stop valve illustrates its structural principle, as accompanying drawing 1.(8) are valve bodies in accompanying drawing 1, (3) be valve gap, rotate handwheel (1), valve rod (2) just relies on its helical thread portion to move up and down in the nut (6) that has logical oil groove, valve rod drives the rubber helical pipe (7) with hemisphere top and finishes the work that opens and closes valve, and rubber helical pipe (7) is pressed on the valve body nut and fluid isolation by nut (6) and valve gap (3); At the oil sealing that is peripherally equipped with oil-containing (5) of nut, oil sealing (5) but can make by the material of felt or other oil-containings, during work, the lubricant oil in the oil sealing can enter helical thread portion by logical oil groove and be lubricated; But oilhole and oil-hole plug (4) that oiling is arranged on valve gap, (9) are the cards that connects rubber helical pipe tube head and valve rod, and valve rod can freely rotate in card.Gate valve also can use same structure, and the shape that only need change the rubber helical pipe when using this structural principle on ball valve gets final product, and it is when making high pressure valve that rubber pipe is done curl, the precession wire spring.

Claims (3)
1, the isolated lubricating type valve of a kind engineering part, constitute by valve body, valve gap, valve rod, handwheel and flap, it is characterized in that between valve body (8) and the valve rod (2) isolated with rubber helical pipe (7), be the nut (6) that has logical chute that partly cooperates with threaded stem below the valve gap, the oil sealing (5) of oil-containing is housed on the nut (6).
2, according to the described isolated lubricating type valve of claim 1, it is characterized in that described rubber helical pipe top is hemispherical, the ripple of tube wall is shape in the shape of a spiral.
3, according to the described isolated lubricating type valve of claim 1, it is characterized in that described oil sealing is contained in the periphery of nut (6).
