Abstract
The invention provides a sluice valve rod protection structure which comprises a valve rod. The valve rod is provided with a hand wheel. The end, on the upper portion of the hand wheel, of the valve rod is provided with a sleeve with the sealed upper end in a sleeving mode. The length of the sleeve is the length of the portion, on the upper portion of the hand wheel, of the valve rod when a valve is completely opened. One side of the sleeve is provided with an oiling hole. The oiling hole is a long hole formed in the axial direction of the valve rod. The sleeve is provided with an internal thread. According to the sluice valve rod protection structure, the end, on the upper portion of the hand wheel, of the valve rod is provided with the sleeve with the sealed upper end in the sleeving mode, rainwater and dust can be prevented from entering the valve rod effectively, and thus lubricating oil (grease) in the valve rod is prevented from being lost.
Description
Technical field
The present invention relates to a kind of operator guards preventing rainwater and dust from entering gate valve rod.
Background technique
In recent years, the communication of China maintains the good momentum of sustained, rapid and sound development, highway construction develops very fast, expressway and town and country Country Road Construction all achieve historical breakthrough, become the important booster rocket of socio-economic development, development highway construction, not only increases transport capacity, and improving the investment climate, optimize in industrial pattern etc. and all can produce important effect.
Pitch is a kind of product of Crude Oil Processing, is thick liquid or the solid of black or black brown at normal temperatures, and it is the organic material as a form of gel of a kind of brownish black.
Straight asphalt refers to the product directly obtained by the method for atmospheric and vacuum distillation by crude oil, a large amount of gate valves is provided with in the pipeline of its manufacturing mechanism, gate valve comprises valve rod, threaded stem connects handwheel, handwheel is protruded in the upper end of valve rod, but a large amount of gate valves is exposed to open-air atmosphere, rainwater and dust enter in valve rod, cause valve rod lubricant oil (fat) to run off.
Summary of the invention
Instant invention overcomes shortcoming of the prior art, provide a kind of gate valve rod operator guards, it effectively prevents rainwater and dust from entering in valve rod; valve rod lubricant oil (fat) is prevented to run off; protected effect is good, and simple and practical, is applicable to very much promoting the use of.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
A kind of gate valve rod operator guards, comprise valve rod, described valve rod is provided with handwheel, and described valve rod has the sleeve pipe of upper end closed at the upper one end cover of handwheel.
Further, described sleeve pipe side has tank filler sleeve.
Further, described tank filler sleeve is along described stem shaft to the elongated hole arranged.
Further, the length of described sleeve pipe is valve valve rod length on handwheel top when entirely opening.
Further, described sleeve pipe has internal thread.
Compared with prior art, the invention has the beneficial effects as follows:
A kind of gate valve rod operator guards of the present invention; comprise valve rod, valve rod is provided with handwheel, and valve rod has the sleeve pipe of upper end closed at the upper one end cover of handwheel; effectively can prevent rainwater and dust from entering, thus prevent lubricant oil in valve rod (fat) to run off.
Accompanying drawing explanation
Accompanying drawing is used to provide a further understanding of the present invention, together with embodiments of the present invention for explaining the present invention, is not construed as limiting the invention, in the accompanying drawings:
Fig. 1 is the structural representation of a kind of gate valve rod operator guards of the present invention;
Fig. 2 is the sleeve structure schematic diagram of embodiment 1.
In figure, 1---pipeline; 2---valve rod;
3---handwheel; 4---sleeve pipe;
5---tank filler sleeve.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
Embodiment 1:
Consult Fig. 1 and Fig. 2; a kind of gate valve rod operator guards of the present invention; the top of pipeline 1 is provided with valve rod 2; valve rod 2 is provided with handwheel 3; valve rod 2 has the sleeve pipe 4 of upper end closed at the upper one end cover of handwheel 3; sleeve pipe 4 is metal material; the length of sleeve pipe 4 is valve valve rod 2 length on handwheel 3 top when entirely opening; tank filler sleeve 5 is had in sleeve pipe 4 side; tank filler sleeve 5 is the elongated hole axially arranged along valve rod 2; for giving valve rod 2 charging-up lubricant oil (fat), sleeve pipe 4 has internal thread, is threaded on valve rod 2.
For the valve that level is installed, the tank filler sleeve 5 of sleeve pipe 4 should be downward.
Embodiment 2:
The present embodiment is substantially identical with embodiment 1 technological scheme, and its difference is:
Sleeve pipe 4 is PVC material, can directly be enclosed within valve rod 2, and such embodiment is applicable to the protection of the lower long valve opening door of field operation frequency.
Last it is noted that these are only the preferred embodiments of the present invention; be not limited to the present invention; although with reference to embodiment to invention has been detailed description; for a person skilled in the art; it still can be modified to the technological scheme described in foregoing embodiments; or equivalent replacement is carried out to wherein portion of techniques feature; but it is within the spirit and principles in the present invention all; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
