Abstract
The utility model relates to a valve rod oil drainage device for a bearing. The valve rod oil drainage device comprises an oil drainage valve rod, an oil drainage valve body, an O-shaped seal ring and a sealing washer, wherein the oil drainage valve body is directly installed on the bearing through a connector, the sealing washer can prevent oil leakage at the connector, the oil drainage valve rod can controls the oil drainage amount according to the screwing-in amount of the valve rod, and the O-shaped seal ring has certain sealing effect so that the oil can not be leaked from the connector of the valve rod. Therefore, the valve rod oil drainage device has the characteristics of simple structure, convenient disassembly and assembly, good sealing effect and the like.
Description
Technical field
The utility model relates to a kind of bearing structure, especially a kind of valve rod jettison gear that is used for bearing.
Background technique
Sliding bearing is the reliable operation that guarantees bearing in long-term using process, must change oil or regularly replaces lubricant oil, especially self oiling bearing according to oily situation, and the drain period is shorter.What therefore, the jettison gear on the bearing just showed is particularly important.And bearing often adopts ball valve as jettison gear at present, and inconvenience is installed on the one hand, must connect by crossover sub; The switch of ball valve does not possess auto-lock function on the other hand, occurs the improper phenomenon of draining the oil easily.
Summary of the invention
The purpose of this utility model is that a kind of easy accessibility of design, using scope are wide, the valve rod jettison gear that is used for bearing of good airproof performance.The technical solution of the utility model is so to realize:
The valve rod jettison gear that is used for bearing comprises the valve body of draining the oil of both end thread interface, and the valve body of draining the oil is provided with the valve rod of the band adjusting nut of a perpendicular layout, and valve rod is provided with a groove, is provided with the O RunddichtringO in it.
As preferably, in the interface at the described valve body two ends of draining the oil, an end is the outside thread interface, and an end is an internal thread interface.This structure can be fit to the bearing interface of inside and outside two kinds of screw threads, improves the using scope of this device
As preferably, the outside thread interface end of the described valve body of draining the oil is provided with sealing gasket, has improved sealing effect, prevents from the jointing leakage of oil.
The valve rod jettison gear of the utility model design, comprise the valve rod of draining the oil, the valve body of draining the oil, O RunddichtringO and seal washer, the valve body of wherein draining the oil is directly installed on the bearing by interface, utilize seal washer can prevent jointing seepage oil, the valve rod of draining the oil can be controlled the flow of draining the oil by the screw-in amount of valve rod, the O RunddichtringO can play certain sealing effect, is unlikely oil and spills from the valve rod joint.Therefore, the utlity model has characteristics such as simple in structure, easy accessibility, good sealing effect.
Description of drawings
Accompanying drawing is a kind of structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing,, the technical solution of the utility model is described in further detail by embodiment.
Embodiment: with reference to the accompanying drawings, be used for the valve rod jettison gear of bearing, comprise the valve body 2 of draining the oil of both end thread interface, in the interface at described valve body 2 two ends of draining the oil, an end is the outside thread interface, and an end is an internal thread interface, and wherein the outside thread interface end is provided with sealing gasket 4.
The valve body 2 of draining the oil is provided with the valve rod 1 of the band adjusting nut 5 of a perpendicular layout, and valve rod 1 is provided with a groove, is provided with O RunddichtringO 3 in it, has improved sealing effect, prevents oil impregnate.
The valve body 2 of draining the oil during use directly is connected on the bearing easy accessibility by interface.
