Abstract
A lubrication mechanism with threads with guiding effect of lifting valve stem comprises a valve body. The valve body is composed of a valve stem, a lubrication mechanism, an inner chamber, a guiding wall, an oil cup, grease, a valve support, and a nut of a valve stem. The lubrication mechanism is arranged at an outer side of the valve stem, i.e. an inner wall of a rising channel lubrication rod. The lubrication mechanism is of a ring shape and surrounds the valve stem; the inner chamber accommodating the grease is arranged inside the lubrication mechanism; and the grease is injected into the inner chamber of the lubrication mechanism through the oil cup connected with the lubrication mechanism. Inner ring surfaces at an upper end and a lower end of the lubrication mechanism are used as the guiding wall, so that the valve stem is uniformly engaged with the nut through screwing, playing the guiding effect during lifting of the valve stem. The beneficial effects of the lubrication mechanism with threads with guiding effect of lifting valve stem are that: friction loss of the valve stem during the process of years of usage is decreased, through the grease injected into the inner chamber of the lubrication mechanism; and the valve stem is uniformly engaged with the nut through screwing, through guiding arrangement of inner ring surfaces at the upper end and the lower end of the lubrication mechanism, so that an off-centered problem caused by weight is eliminated during the lifting process of the valve stem.
Description
Technical field
The utility model relates to valve and makes the field, is specifically related to a kind of rise-fall type stem guiding and screw thread lubricating structure.
Background technique
In common valve using process,, even also can cause thread abrasion and influence the function of use of valve often owing to valve rod influences working life with screw thread generation frictional loss easily in using process throughout the year.And valve rod in lifting process because weight causes the problem of setovering easily, aggravated thread abrasion, bring unnecessary trouble to using valve.Therefore the utility model solves the problems referred to above by lubricating structure is set in valve.
The model utility content
The utility model is to provide a kind of at rise-fall type stem guiding that possesses wear-resisting property and screw thread lubricating structure for solving the problems of the technologies described above.
The technical problem that the utility model solved realizes by the following technical solutions:
A kind of rise-fall type stem guiding and screw thread lubricating structure, comprise valve body, described valve body is by valve rod, lubricating structure, inner chamber, guide wall, lubricating cup, lubricating grease, valve rack, Stem Mut is formed, described lubricating structure is arranged on the outside of valve rod, promptly lubricate the inwall of valve rod hoist trunk, the cylindrical shape of described lubricating structure, described lubricating structure shape ringwise surrounds valve rod, described lubricating structure inside is provided with the inner chamber that holds lubricating grease, inner chamber is located at the central space of lubricating structure, play the function of oil groove, lubricating grease injects to the inner chamber of lubricating structure by the lubricating cup that links to each other with lubricating structure, lubricating cup is located at the outside of lubricating structure, be installed on the inwall of valve rack and play function from lubricating grease to lubricating structure that inject, described guide wall is located at the upper and lower end inner ring surface of lubricating structure, described lubricating structure upper and lower end also is provided with guide wall, described guide wall contacts closely with valve rod, make valve rod and nut evenly screw, can also play good leading role to the valve rod lifting when described guide wall can play closed inner chamber, can not occur in the common valve using process because weight produces the problem of valve rod biasing.
