Description
Technical field
The utility model relates to Pipe Control Unit fields, and in particular to a kind of valve rod protective device.
Background technique
To reinforce pipeline control, petrochemical equipment is needed using a large amount of control valve.Valve in use, valve rod
It is chronically exposed in air, generally has no and targetedly protect anti-corrosion measure.Therefore, after long-time use, valve rod is viscous
Attached dirt is husky, is easy corrosion, causes valve to be difficult to open, makes troubles to production, and buries security risk.
Utility model content
To overcome defect of the existing technology, the utility model, which provides one kind, can facilitate production, eliminate safe hidden trouble
Valve rod protective device.
Its technical solution is：Including top valve rod rubber protecting jacket, middle part valve rod rubber protecting jacket；The top valve rod rubber
Glue protective case, including the first rubber tube and its top are used for closed serum cap；First rubber sleeve is loaded on valve handle
On valve rod more than fixture nut；Valve rod leakage length when the slightly greater height than valve wide open of first rubber tube；Described
The internal diameter of one rubber tube is slightly larger than valve rod size；First rubber tube sets that there are two rubbers at open one end diagonal line
Glue cone, for being stuck in valve rod screw thread, so that top valve rod rubber protecting jacket can be moved up with the unlatching of valve, and makes
Portion's valve rod rubber protecting jacket will not fall off when valve wide open, leakage valve rod are shorter；The middle part valve rod rubber protecting jacket includes
The second rubber tube equipped with vertical scarfing；Second rubber sleeve is loaded on valve rack or less, exposed valve rod more than valve body
On；The height of second rubber tube depends on exposed shaft length；The internal diameter of second rubber tube is slightly larger than valve rod
Size；The vertical scarfing two sides of second rubber tube are equipped with Quick connection part.
Above-mentioned technical proposal can advanced optimize for：
The bottom inside of first rubber tube is equipped with groove, convenient for being buckled on the outside of valve rod copper sheathing to improve sealing effect.
The Quick connection part uses plastics eye-splice.
The material of the top valve rod rubber protecting jacket uses oil resistant, age inhibiting transparent rubber.
The material of second rubber tube uses oil resistant, anti-aging rubber.
The thickness of first rubber tube, serum cap and the second rubber tube is not less than 2 millimeters.
The top valve rod rubber protecting jacket, middle part valve rod rubber protecting jacket are smeared in stem surface in advance before the mounting
Lubricant grease.
The beneficial effects of the utility model are as follows：
1. structure is simple, easy for installation.
2. being easy production, Maintenance free during use, at low cost, the service life is long.
3. can be effectively protected valve rod is in lubricating status, avoids valve rod adherency dirt sand, gets rusty, thoroughly eliminate and thus bring
Production is inconvenient and security risk.
4. the use of transparent rubber is convenient for the dynamic change of observation valve opening degree in time.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
In figure：1- serum cap, the first rubber tube of 2-, 3- rubber cone, 4- valve rod, the second rubber tube of 5-, the vertical scarfing of 6-, 7-
Plastics eye-splice.
Specific embodiment
The utility model will be further described with reference to the accompanying drawing：
Referring to Fig. 1.A kind of valve rod protective device, including the protection of top valve rod rubber protecting jacket, middle part valve rod rubber
Set.Top valve rod rubber protecting jacket, including the first rubber tube and its top are used for closed serum cap.First rubber sleeve is loaded on
On valve rod more than valve handle fixture nut.Valve rod leakage length when the slightly greater height than valve wide open of the first rubber tube.The
The internal diameter of one rubber tube is slightly larger than valve rod size.First rubber tube sets that there are two rubber at open one end diagonal line
Cone, for being stuck in valve rod screw thread, so that top valve rod rubber protecting jacket can be moved up with the unlatching of valve, and makes top
Valve rod rubber protecting jacket will not fall off when valve wide open, leakage valve rod are shorter.The bottom inside of first rubber tube is equipped with groove,
Convenient for being buckled on the outside of valve rod copper sheathing to improve sealing effect.The rubber used of top valve rod rubber protecting jacket, which removes, to be had oil resistant, prevents
Outside the performance of aging, had better transparent rubber, to observe the dynamic change of valve opening degree in time.Middle part valve rod rubber
Protective case includes the second rubber tube equipped with vertical scarfing.Second rubber sleeve is loaded on outer below valve rack, more than valve body
Reveal on valve rod.The height of second rubber tube depends on exposed shaft length.The internal diameter of second rubber tube is slightly larger than valve rod ruler
It is very little.To prevent vertical scarfing from influencing sealing effect, the vertical scarfing two sides setting plastics eye-splice of the second rubber tube, which is used as, quickly to be connected
Fitting.The material of second rubber tube uses oil resistant, anti-aging rubber.The thickness of first rubber tube, serum cap and the second rubber tube
Not less than 2 millimeters, to ensure longer service life.Bring inconvenience and safety are corroded to be preferably inherently eliminated valve rod
Hidden danger, top valve rod rubber protecting jacket, middle part valve rod rubber protecting jacket are before the mounting in advance in stem surface coating lubricating oil
Rouge.
The working principle of the utility model is as follows：
After valve is installed, top valve rod rubber protecting jacket is put on along valve rod screw thread.When Open valve, only need to rotate
Handwheel, top valve rod rubber protecting jacket are moved up with valve rod；When closing valve, with hand by top valve rod rubber protecting jacket along under valve rod
Shifting.When the valve rod rubber protecting jacket of installation middle part, valve rod is packed into from vertical scarfing.
The above, is only the preferred embodiment of the utility model, and anyone skilled in the art may benefit
It is practical new to belong to the greatest extent this for any simple modification carried out with the technical solution of above-mentioned elaboration to the utility model or substitute equivalents
The claimed range of type.
