Abstract
The invention discloses a valve-stem nut lubrication device which comprises a valve-stem nut and is characterized by also comprising a valve-stem nut gland. The valve-stem nut gland is arranged at the periphery of the valve-stem nut; the inside at one side of the valve-stem nut gland is also provided with an oil cup; an oil filling opening of the oil cup is communicated with the valve-stem nut; and the peripheral surface of the valve-stem nut is provided with an oil storage tank which corresponds to the oil filling opening of the oil cup. The fixed valve-stem nut gland is arranged at the periphery of the valve-stem nut, and therefore, the valve-stem nut gland can be used for positioning the valve-stem nut. In addition, the inside at one side of the valve-stem nut gland is provided with the oil cup, and the oil storage tank is arranged on the valve-stem nut correspondingly, therefore, the valve-stem nut can be effectively lubricated, the surface wear of the valve-stem nut can be reduced, and the service life of the valve-stem nut can be prolonged. In addition, the oil storage tank is in a helical structure, and the lubrication effect can be improved when the surface of the valve-stem nut is lubricated in large area.
Description
Technical field
The present invention relates to a kind of lubricating fitting, especially relate to a kind of lubricated device of Stem Mut that is used for, belong to valve accessories.
Background technique
Gate valve is as a kind of valve by medium, extensive use in the valve industry, and whole runner is straight-through when standard-sized sheet, the pressure loss minimum of medium operation this moment, it is applicable to does not need frequent keying and keeps valve to be in the operating mode of standard-sized sheet or full cut-off.At present, gate valve all is to realize moving up and down of valve rod by being used of valve rod and Stem Mut, promptly the upper position at Stem Mut is equipped with handwheel, rotate handwheel rotary valve rod nut, and valve rod and Stem Mut are by being threaded, Stem Mut is delivered to valve rod with the motion and the keying moment of handwheel, and Stem Mut can only rotate, can not produce upper and lower displacement, therefore can realize moving up and down of valve rod, the Stem Mut of traditional gate valve is arranged in the support case, in the opening-closing process of valve, tend to ignore the lubricated of Stem Mut surface, make Stem Mut in rotating process, its surface is easy to be worn, thereby can reduce its working life.
Summary of the invention
In order to overcome the deficiencies in the prior art, the object of the present invention is to provide the parallel sliding gate valve of a kind of simple in structure, good seal performance, load dispersion, valve seat long service life.
The present invention is achieved through the following technical solutions:
A kind of valve-stem nut lubrication device, comprise Stem Mut, it is characterized in that: also comprise the Stem Mut letter, the Stem Mut letter is arranged on the outside of Stem Mut, side inside at the Stem Mut letter also is provided with lubricating cup, and the rim of a cup of lubricating cup is provided with bowl cover, and the pouring orifice of its other end then leads to Stem Mut, the outer circumferential face of Stem Mut is provided with the oil storage tank corresponding with the pouring orifice of lubricating cup, and described oil storage tank is a sped structure.
The invention has the beneficial effects as follows: the present invention is provided with the Stem Mut letter by the outside at Stem Mut, and the Stem Mut letter is fixed, the location that then can be used for Stem Mut, in a side inside of Stem Mut letter lubricating cup is set in addition, oil storage tank is set on Stem Mut accordingly, then can realize effectively lubricating, reduce the surface abrasion of Stem Mut, prolong its working life Stem Mut.In addition.Oil storage tank is a sped structure, then the Stem Mut surface is carried out large-area lubricated, strengthened lubrication effect.
Description of drawings
Fig. 1 is the plan view of Stem Mut part of the present invention;
Fig. 2 is the side view of Stem Mut part of the present invention.
Main reference character implication is among the figure:
1, valve rod 2, Stem Mut 3, Stem Mut letter 4, lubricating cup 5, oil storage tank
Embodiment
Below in conjunction with accompanying drawing, describe the specific embodiment of the present invention in detail:
Fig. 1 is the plan view of Stem Mut part of the present invention; Fig. 2 is the side view of Stem Mut part of the present invention.
As depicted in figs. 1 and 2: valve rod 1 is threaded with Stem Mut 2, the upper position of Stem Mut 2 is provided with handwheel 6, in the bottom of handwheel 6, the lower, outer perimeter of Stem Mut 2 encloses and also is provided with Stem Mut letter 3, one side inside of Stem Mut letter 3 is provided with lubricating cup 4 lubricating cups 4 rims of a cup and is provided with bowl cover, and the pouring orifice of its other end then leads to Stem Mut 2 Stem Muts 2 outer circumferential faces and is provided with the spiral oil storage tank 5 corresponding with lubricating cup 4 pouring orifices.
Rotate handwheel 6, drive Stem Mut 2 rotations, Stem Mut 2 is delivered to valve rod 1 with the motion and the keying moment of handwheel 6, and in rotation process, Stem Mut letter 3 is fixed, being positioned at its inner Stem Mut 2 can only rotate, and can not produce upper and lower displacement, therefore can realize moving up and down of valve rod 1, and then open-shut device such as the flap realization that drives valve rod 1 bottom and be positioned at valve body moves up and down, in the using process of valve, Stem Mut 2 is in the process of rotation, its surface can contact with Stem Mut letter 3, be easy to generate wearing and tearing, therefore, can be aperiodically to the surperficial oiling of Stem Mut 2, to play lubrication, after promptly opening bowl cover, to Stem Mut 2 surperficial oilings, oil enters oil storage tank 5 by lubricating cup 4, because Stem Mut 2 lip-deep oil storage tanks 5 are screw type, therefore in the rotary course of Stem Mut 2, can be in large area the surface of revolution of Stem Mut 2 be lubricated, make lubrication effect reach the optimum state, effectively reduce the wearing and tearing of Stem Mut 2, prolonged the working life of Stem Mut 2.
Below disclose the present invention with preferred embodiment, so it is not in order to restriction the present invention, and all employings are equal to replaces or technological scheme that the equivalent transformation mode is obtained, all drops within protection scope of the present invention.
