Description
Technical field
The utility model is related to valve technology field, and in particular to a kind of balanced three-way governing valve.
Background technology
In existing triple valve, because the requirement of technique by inlet fluid, it is necessary to be divided into two strands of outlet fluids or by two
Stock inlet fluid synthesizes one outlet fluid, replaces two straight-through single-seat valves.
But existing triple valve has the following disadvantages：Valve in the process of running, after valve plug closing, deposit by valve plug both sides
In pressure difference, valve plug is opened difficult, it is desirable to provide the executing agency of high thrust；In addition, fluid enter valve plug in can produce impulse force with
And vortex, easily the job stability of valve plug is made a big impact.
Utility model content
There is pressure difference to overcome background technology valve plug, open difficult, the defect such as poor work stability, the utility model is carried
For a kind of balanced three-way governing valve.
The technical scheme that the utility model is used：A kind of balanced three-way governing valve, including valve body, bonnet, valve seat, valve
Bar and valve plug, the bonnet are fixedly mounted on above the valve body, and the valve body is provided with right runner and left stream positioned at side wall
Road and the sprue positioned at the valve body bottom, the valve plug are moveably mounted to the valve by the drive of the valve rod
In vivo, it is additionally provided with the valve body and the valve interior wall and upper bush corresponding with the right runner is pressed on by the bonnet
And by the seat compression in the valve interior wall and lower sleeve corresponding with the left runner, the upper bush is with trapping
It is provided between cylinder and seals the wedge coordinated with the valve plug, the valve plug is in straight barrel type, and the valve plug lateral wall is provided with around circle
Heart etc. point is set and in the balance pipe of same sagittal plane.
The balance pipe is elongated, and the upper bush is provided with the through hole being adapted to the balance pipe.
The both sides of the wedge and valve plug and valve body contact are designed with O-ring and accumulation of energy sealing ring.
The O-ring uses fluorubber, and the valve plug, upper bush, lower sleeve and accumulation of energy sealing ring all use polytetrafluoro
Ethene.
It is provided between the bonnet and valve rod above filler, the filler and is additionally provided with the gland being fixedly mounted with the bonnet
And clamping is arranged on the gland between the gland and filler.
The beneficial effects of the utility model are：By setting balance pipe in side wall, valve plug is set largely to be solely subjected to radially negative
Carry, the opening of valve plug is greatly reduced with closing by the obstruction of fluid, can use the executing agency of more low thrust；Meanwhile, balance
Hole decile, which is arranged on the outer circumference surface of valve plug, can effectively reduce fluid to the impact inside valve plug, extend the use of valve plug
Life-span makes valve operation more stable, more reliable.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment balanced three-way governing valve.
Fig. 2 is the partial enlarged drawing at A in Fig. 1.
Embodiment
The utility model embodiment is described further below in conjunction with the accompanying drawings：
As illustrated, a kind of balanced three-way governing valve, including valve body 1, bonnet 2, valve seat 3, valve rod 4 and valve plug 5, institute
