Abstract
The utility model discloses a kind of super-pressure ono-rising-stem valve valve rod bindiny mechanisms, valve rod (1) connect with valve plate (10) and is installed in valve body (9) by valve deck (11), valve rod crossover sub (5) is mounted on valve rod (1) by No.1 pin shaft (4), handwheel (8) is mounted on the upper end of valve rod crossover sub (5), bearing block (2) is by being threadably mounted on valve rod (1) and by No. two pin shaft (12) lockings, bearing cap (7) are installed outside bearing block (2), No.1 pin shaft (4) and No. two pin shafts (12) install sheath (6) and dustband (3) outside.Using being threadedly coupled between the valve rod of the utility model and bearing block, stress intensity is high, can effectively bear the pressure from valve chamber, use under ultra-high voltage environment, solve the switch problem of Super high pressure valve, improve the service life of valve.
Description
Technical field
The utility model relates to valves, and in particular to a kind of valve rod connection machine of the ono-rising-stem valve used under ultra-high voltage environment
Structure.
Background technique
Currently, the valve rod and valve rod crossover sub of ono-rising-stem valve are connected with pin shaft, under ultra-high voltage environment in use,
Valve rod is moved up by the effect of high pressure in valve chamber, and pin shaft is caused to fracture, so that valve switch be made to fail.
Summary of the invention
The purpose of this utility model is that: a kind of super-pressure ono-rising-stem valve valve rod bindiny mechanism is provided, in ultra-high voltage environment
Lower use, solves the switch problem of Super high pressure valve, improves the service life of valve.
The technical solution of the utility model is: the valve includes valve body, valve deck and valve rod, and valve rod is connect simultaneously with valve plate
It is installed in valve body by valve deck, valve rod crossover sub is mounted on valve rod by No.1 pin shaft, and handwheel is mounted on valve rod conversion
The upper end of connector；It is characterized in that: also install valve rod bindiny mechanism on valve rod, the valve rod bindiny mechanism include bearing block,
Bearing cap, sheath and dustband, bearing block is by being threadably mounted on valve rod and by No. two lock clasps, bearing block outside peace
Bearing cap is filled, sheath and dustband are installed outside No.1 pin shaft and No. two pin shafts.
The utility model has the advantages that: using being threadedly coupled between valve rod and bearing block, stress intensity is high, can effectively bear
Pressure from valve chamber.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1 valve rod, 2 bearing blocks, 3 dustbands, 4 No.1 pin shafts, 5 valve rod crossover subs, 6 sheaths, 7 bearing caps, 8 hands
Wheel, 9 valve bodies, 10 valve plates, 11 valve decks, 12 No. two pin shafts.
Specific embodiment
As shown in Figure 1, the valve includes valve body 9, valve deck 11 and valve rod 1, valve rod 1 connect with valve plate 10 and by valve deck 11
It is installed in valve body 9, valve rod crossover sub 5 is mounted on valve rod 1 by No.1 pin shaft 4, and handwheel 8 is mounted on valve rod crossover sub
5 upper end；It is characterized in that: also installing valve rod bindiny mechanism on valve rod, the valve rod bindiny mechanism includes bearing block 2, axis
Lid 7, sheath 6 and dustband 3 are held, bearing block 2 is by being threadably mounted on valve rod 1 and locking by No. two pin shafts 12, bearing block 2
Outside installation bearing cap 7, No.1 pin shaft 4 and No. two pin shafts 12 install sheath 6 and dustband 3 outside.
