Abstract
The utility model discloses a valve rod protecting device, which comprises a valve rod sleeve, a side cover, a support, a valve rod and a valve rod grease-injecting valve and mainly solves the problem that a valve rod of a valve in the open air in a long term is rusted easily. The valve rod protecting device is characterized in that the valve rod sleeve (7) is sleeved at the upper end of the valve rod (1), a transparent cover (9) is installed on the valve rod sleeve (7) through a screw (10), an indication rod (10) and an indicator (11) are arranged at the top end of the valve rod (1), the support (2) is sleeved in the middle of the valve rod (1), filler replacing openings are arranged on two sides of the support (2), the side cover (4) is fixed on the support (2) through a bolt (6) and a sealing gasket (5), and the valve rod grease-injecting valve (3) is installed on the side face of a valve cover (12). The valve rod protecting device can effectively protect and lubricate the valve rod, prevents the valve rod from rusting, and has the advantages of being simple in structure and convenient to use.
Description
Technical field
The utility model relates to valve upper valve rod protection structure, particularly relates to a kind of valve rod protective gear.
Background technique
In Coal Chemical Industry, in the industries such as open pit oil mining, all be connected with valve on some transfer line at present; Because production needs, long-term open-air placement of some valves, the valve rod on these valves is directly exposed to the outside; Valve rod lacks protection, and threaded stem is stained with dirt sand, perhaps by the corrosion of rain and dew frost and snow institute; Valve rod of long duration will get rusty in such environment, causes the valve switch difficulty, even stuckly can't open or close valve.In order to address this problem, general valve manufacturer can directly spread upon stem exterior surface with lubricating grease, can adhere to foreign material such as sandstone on the lubricating grease, when throttle down, is prone to make valve stuck.Also have people may take a valve integral body to wrap up, but when valve uses for a long time, when filler lost efficacy, can't change.Perhaps the operator can't judge the valve opening and closing position.
Summary of the invention
For the problem that the valve rod that solves open-air valve is prone to get rusty, the utility model provides a kind of valve rod protective gear, and this valve rod protective gear can be protected valve rod effectively, avoids valve rod to get rusty, and has characteristics simple in structure, easy to use.
The technological scheme of the utility model is: a kind of valve rod protective gear, the valve gap of stem lower portion and valve gap joint are provided with the grease pouring valve that injects lubricating grease to valve rod, and the valve rod middle part is provided with the filler replacement port, and the valve rod top is with valve stem casing.
Grease pouring valve is arranged on the valve gap side.
The valve rod middle part is with support, and the filler replacement port is arranged on the support both sides, and the filler replacement port has side cover, and side cover is fixed on side cover on the support through bolt and gasket seal.
Valve stem casing has a transparent cover, and transparent cover is installed on the valve stem casing through screw, and valve stem tip has indicating arm and pointer.
The utlity model has following beneficial effect: owing to take such scheme, the valve rod that valve stem casing can umbrella gear upper end, the fixing pointer of valve stem tip can the easy-to-operat person be observed the position of valve opening and closing.There is the support of complete closed at the valve rod middle part, can protect valve rod limitedly, avoids valve rod to get rusty, and valve gap valve gap side is equipped with the valve rod grease pouring valve, through injecting lubricating grease, valve rod is lubricated effect, and this apparatus structure is simple, and is easy to use.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Combine Fig. 2, Fig. 3 and shown in Figure 4 by Fig. 1, this valve rod protective gear comprises valve stem casing 7, side cover 4, support 2, valve rod 1, valve rod grease pouring valve 3.Valve rod 1 upper end is with valve stem casing 7; Transparent cover 9 is installed on the valve stem casing 7 through screw 10; And valve rod 1 top has indicating arm 10 and pointer 11, and valve rod 1 middle part is with support 2, and support 2 both sides have the filler replacement port; Be fixed on side cover 4 on the support 2 through bolt 6 and gasket seal 5, valve gap 12 sides are equipped with valve rod grease pouring valve 3.This valve rod protective gear can effectively be protected valve rod, and lubricated valve rod avoids valve rod to get rusty, and has characteristics simple in structure, easy to use.
More than show and described the advantage of basic principle, major character and the utility model of the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
