Description
Technical field
The present invention relates to valve technology field, more particularly to one kind can on-line maintenance lower guideway orbit ball valve.
Background technology
Ball valve has simple in construction, and switch is rapid, the advantages of flow resistance is small, can be cut off, distribution and changes the crowds such as medium flow direction
Multipurpose, is widely used in the row such as petroleum refining, long-distance transport pipes, chemical industry, papermaking, pharmacy, water conservancy, electric power, municipal administration, steel
Industry, in national economy occupy proportion increases year by year.On some specific occasions, some large-scale pipelines, orbit ball valve should
With more and more extensive.Orbit ball valve moment of torsion in switching process is small, so as to reduce actuator cost.And sealing surface is in switching process
In almost zero friction, so as to increase the service life.
Currently, the most orbit ball valve of in the market using upper rail drive spheroid rotation, i.e., valve rod in lifting process simultaneously
Rotation, so that drive spheroid to rotate, therefore it is high to valve rod intensity requirement, production cost will increase.Alignment pin bears to rise simultaneously
The frictional force of rotation is dropped also than larger, and is linear contact lay friction, contact site stress is larger, so that valve rod guide groove is easy to damage
It is bad.Expansion ring structure is used between existing most of orbit ball valve valve seat and valve body, reason is that ball seal face will in switching process
Depart from sealing surface of seat, so valve seat has to fix.But this structure can not realize on-line maintenance, if valve seat is damaged
It is bad, then valve must be pulled down to maintenance, this is just to using causing many inconvenience.
In order to solve the above-mentioned technical problem, one kind of the present invention can on-line maintenance lower guideway orbit ball valve, the ball valve
It is to change orbit ball valve stem structure, the bottom of valve rod is changed to helical guideway, is changed into lower guideway, upper rail is changed by helicla flute
For straight trough, correspondence straight trough is provided with alignment pin, so that valve rod, which is only lifted, not to be rotated, so as to allow between alignment pin and valve rod
Face contact is changed to by linear contact lay, stem wear is reduced, strengthens switch motion continuity, increase the service life.The purpose of the present invention
It is to change valve seat construction, is moved with pendant collet limitation valve seat, screw fixes pendant collet and prevents from dropping out.Valve seat is set to fix, again
Maintenance can be dismounted online, brought convenience to user.And it is suitable for the operating modes such as various high/low temperatures, high-low pressure.In opening process
Middle valve rod drives spheroid to depart from valve seat by helical guideway, makes sealing surface almost zero abrasion, increases the service life.And switch is turned round
Square very little, production cost can be reduced by choosing the small actuator of output torque, and with more preferable using effect.

On support, the alignment pin pressing plate is provided with lubricating coupler.
It is preferred that the pivot bottom be in circular arc.
It is preferred that the bottom of the helical guideway be straight flat formula structure.
It is preferred that the valve body and valve seat between be provided with gasket seal one.
It is preferred that the valve body and bonnet between be provided with gasket seal two.
One kind of the present invention can on-line maintenance lower guideway orbit ball valve, the ball valve be change orbit ball valve valve rod knot
Structure, helical guideway is changed to by the bottom of valve rod, is changed into lower guideway, and upper rail is changed to straight trough by helicla flute, and correspondence straight trough is provided with fixed
Position pin, so that valve rod, which is only lifted, not to be rotated, is changed to face by linear contact lay between alignment pin and valve rod and contacts, subtract so as to allow
Few stem wear, strengthens switch motion continuity, increases the service life.It is an object of the invention to change valve seat construction, with four
Open loop limitation valve seat movement, screw fixes pendant collet and prevents from dropping out.Valve seat is fixed, maintenance can be dismounted online again, to making
User brings convenience.And it is suitable for the operating modes such as various high/low temperatures, high-low pressure.Valve rod is driven by helical guideway in opening process
Spheroid departs from valve seat, makes sealing surface almost zero abrasion, increases the service life.And switching torque very little, choose output torque small
Actuator can reduce production cost, and with more preferable using effect.
