Description
Technical field
The utility model belongs to floating ball valve technical field, and in particular to a kind of floating of valve rod emergency sealing greasing structure
Ball valve.
Background technique
Currently, ball valve has a wide range of application due to the features such as flow resistance is small, switch is rapid, good seal performance, long service life
It is general.Floating ball valve is one kind important in ball valve, has the characteristics that close structure, sealed reliable, structure are simple, easy to maintenance,
Suitable for the general works medium such as water, solvent, acid and natural gas, but also be suitable for the severe medium of operating condition, as oxygen,
Methane and ethylene etc. are widely used in every profession and trade.Existing frequently-used floating ball valve, valve rod and valve body installation gap are to use
O-ring or flexible graphite sealing, valve use for a long time on pipeline, and valve opening and closing is frequent, and O-ring and soft graphite are easily
It damages and external leakage occurs, present structure does not have a kind of effective measures to carry out emergency sealing, so that valve be made to use in pipeline
In there are security risks.
Summary of the invention
(1) technical solution
In order to overcome the shortage of prior art, the utility model provides a kind of float ball of valve rod emergency sealing greasing structure
Valve, the floating ball valve include valve body, and valve seat is equipped in the valve body, and sphere, the valve body side dress are installed on the valve seat
There is valve deck, is coupled between the valve body and the valve deck by stud and nut, it is fixed on the top surface of the sphere
Valve rod, the valve rod pass through valve body and are fixedly connected with spanner, and the spanner band ovable valve stem was realized and rotated when use, the valve rod band
Move sphere rotation, to realize the unlatching and closure of valve, be equipped between the valve rod and the valve body the first O-ring and
Second O-ring has a greasing hole, fills on the greasing hole and the valve rod between first O-ring and second O-ring
Greasing oil nozzle communicate, the bottom junction horizontal plane of the valve body and the valve deck is equipped with third O-ring.
Further, the top surface of the valve body passes through the fixed spanner of hexagon socket head cap screw.
Further, the junction of the valve body and the valve deck is equipped with seal washer, and the seal washer passes through
Rubber material is prepared.
Further, the bottom surface of the spanner and the top surface junction of the valve body are equipped with is prepared by pvc material
Retaining ring.
When first O-ring and second O-ring occur breakage can not seal leak outside when, greasing can be passed through
Oil nozzle injection stop-leak compound carrys out emergency sealing valve, provides time and safety guarantee for valve maintenance, effectively improves the safety of valve
Property and reliability.
(2) beneficial effect
The utility model has the beneficial effects that compared with the prior art, the utility model is when valve rod and valve leak outside
Emergency sealing measure is provided, time and safety guarantee is provided for valve maintenance, effectively improves the safety and reliability of valve, and
And design structure is simple, manufacturing cost is low, easily promotes, and the valve for solving the prior art uses for a long time on pipeline, valve
The technical issues of door opening and closing is frequent, and O-ring and soft graphite easily damage and external leakage occur.
Detailed description of the invention
Fig. 1 is the structural section figure of the floating ball valve of valve rod emergency sealing greasing structure.
Specific embodiment
The utility model is further described below with reference to embodiment.
Embodiment one
As shown in Figure 1, the implementation case provides a kind of floating ball valve of valve rod emergency sealing greasing structure, the float ball
