Description
Technical field
This utility model is related to formula venting ball valve is filled on valve technology field, more particularly to one kind.
Background technology
Ball valve is a kind of widely used valve, and which is that opening and closing element is driven by valve rod, and is rotated 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
Change the flow direction of medium, it only needs to tight, ball valve can be just closed with the rotating torque of the operation and very little that are rotated by 90 °
Optimum is switched, stop valve is used.
Which in the application, when needing needed for repair and replacement in the event of damage, need to be pulled down from pipeline, program by ordinary ball valve
Tediously long, the consuming time is long, and the damage of the ball valve overwhelming majority is all sealing problem caused by sealing surface damage, if can only more
Change sealing surface and do not remove valve body, then maintenance time will substantially reduce, upper-mounting type ball valve break down on pipeline need repair
When, it is not necessary to valve is dismantled from pipeline, need only dismantle middle flange bolt and nut, by valve gap and valve rod group component together from valve body
In take off, then take out spheroid and valve seat combination part, you can online to repair spheroid and valve seat, this maintenance saves the time,
Loss in production is bottomed out.
The shortcoming of upper dress formula fixing ball valve is that initial tension of spring can not be adjusted and be controlled, and amount of spring compression when assembling
Greatly, assemble difficult；The presence of gas is had in pipeline often, these gases can cause cavitation erosion, damage valve and pipeline to valve,
Its service life is reduced, for the minimum gas in the duct for just producing or produced, needs to discharge it, it is general in pipeline
Special air bleeding valve can be set, but special air bleeding valve density of setting is limited, aerofluxuss burden weight, it is impossible to comprehensive protective conduit and valve
Door.
The content of the invention
This utility model aims to solve the problem that the deficiencies in the prior art, and provides, and the ball valve is keeped in repair
Convenient and swift, gas that can be in discharge line reduces the cavitation erosion of pipeline and valve, increases the service life of valve and pipeline.
This utility model for achieving the above object, is employed the following technical solutions：Formula venting ball valve, including valve are filled in one kind
Body, valve seat, spheroid, valve rod and valve gap, located at body cavity at valve latus rectum, the valve seat is cylindrical for two valve seats
Outermost section forms sealing pair with valve body, and the cylindrical interlude of the valve seat is provided with screw thread, adjusting nut, the tune are cased with screw thread
Spring is provided between section nut and valve body, the spring setting direction is set parallel to media flow direction in valve, the spheroid
Between two valve seats, spheroid and two valve seats form sealing pairs, the valve gap above valve body, valve gap and valve body shape
Into sealing pair, the valve rod is inserted in the middle part of spheroid through in the middle part of valve gap, and airtight and watertight padding is provided between the valve rod and valve gap, described
Airtight and watertight padding top is provided with gland, and the gland is with bolts with valve gap, and the valve rod passes through gland, sets on the valve gap
There is air bleeding valve, the air bleeding valve is connected 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 beneficial effects of the utility model are：This utility model adopts upper dress formula, easy to maintenance quick；Valve gap is provided with row
Air valve is connected with body cavity, minimum gas that can in time in discharge line, and aggregation is discharged in time in a large number to reduce gas
The significant damage probability caused by pipeline；Reduce the aerofluxuss burden of tube exhaust valve, increased its service life；Reduce ball
The phenomenon that the spheroid and sealing surface of seat of valve is cavitated by minimum gas, increased ball valve service life；Valve seat is cylindrical to be provided with regulation
Nut, adjusts the pretightning force of spring by adjusting nut, reduces assembly difficulty.
