Description
Technical field
The present invention relates to valve technology field, particularly relate to dress formula venting ball valve in one.
Background technology
Ball valve is a kind of widely used valve, and it is driven by valve rod for opening and closing element, and rotates around ball valve axis
Valve, opening and closing element is spheroid, for regulation and the control of fluid, ball valve is mainly used to cut off in pipeline, distribute and
Changing the flow direction of medium, it has only to the operation with 90-degree rotation and the least rotating torque just can be closed tight, ball valve
Optimum switchs, stop valve uses.
It in the application, during if it occur that damage needs needed for repair and replacement, need to be pulled down, program from pipeline by ordinary ball valve
Tediously long, expend the time long, and the overwhelming majority of damaging of ball valve is all that sealing surface damages the sealing problem caused, if can the most more
Changing sealing surface and do not remove valve body, then will be substantially reduced maintenance time, upper-mounting type ball valve breaks down on pipeline to be needed to repair
Time, it is not necessary to from pipeline dismantle valve, need only dismantle middle flange bolt and nut, by valve gap together with valve rod group component from valve body
In take off, then take out spheroid and valve seat combination part, spheroid and valve seat can be repaired online, this maintenance saves the time,
Loss in producing bottoms out.
The shortcoming of upper dress formula fixing ball valve is that initial tension of spring can not adjust and control, and amount of spring compression when assembling
Greatly, assembling difficulty；Often having the existence of gas in pipeline, valve can be caused cavitation erosion by these gases, damages valve and pipeline,
Reduce its service life, for the minimum gas in the duct just producing or having produced, need to discharge it, general in pipeline
Special air bleeding valve can be set, but special air bleeding valve density of setting is limited, aerofluxus burden weight, it is impossible to protective conduit and valve comprehensively
Door.
Summary of the invention
Present invention seek to address that the deficiencies in the prior art, and provide dress formula venting ball valve in one, this ball valve is easy to maintenance
Fast, can gas in discharge line, reduce pipeline and the cavitation erosion of valve, increase valve and the service life of pipeline.
The present invention for achieving the above object, by the following technical solutions: dress formula venting ball valve in one, including valve body, valve
Seat, spheroid, valve rod and valve gap, two described valve seats are located at body cavity at valve latus rectum, the outermost of described valve seat cylindrical
Section forms sealing pair with valve body, and the interlude of described valve seat cylindrical is provided with screw thread, is cased with adjusting nut, described regulation spiral shell at screw thread
Being provided with spring between mother and valve body, described spring setting direction is parallel to valve medium flow direction, and described spheroid is located at two
Between individual described valve seat, spheroid and two valve seats form sealing pair, and described valve gap is located at above valve body, and valve gap and valve body are formed close
Envelope pair, described valve rod inserts in the middle part of spheroid in the middle part of valve gap, is provided with airtight and watertight padding, described sealing between described valve rod and valve gap
Filler top is provided with gland, and described gland is with bolts with valve gap, and described valve rod passes gland, and described valve gap is provided with row
Air valve, described air bleeding valve connects with body cavity.
Described valve stem tip is provided with rotary handle.
Described valve gap is with bolts with valve body.
Described airtight and watertight padding is v-ring.
Described airtight and watertight padding quantity is not less than 4.
Described air bleeding valve quantity is 2.
The invention has the beneficial effects as follows: the present invention uses the formula of dress, easy to maintenance fast；Valve gap is provided with air bleeding valve and valve
Intracoelomic cavity connects, can the minimum gas in discharge line in time, reduce gas and assemble discharge in time in a large number pipeline is made
The significant damage probability become；Reduce the aerofluxus burden of tube exhaust valve, add its service life；Decrease the spheroid of ball valve
The phenomenon cavitated by minimum gas with sealing surface of seat, adds ball valve service life；Valve seat cylindrical is provided with adjusting nut, passes through
Adjusting nut adjusts the pretightning force of spring, makes assembly difficulty reduce.
