Description
Technical field
The utility model is related to valve fields, and in particular to a kind of adjustable ball valve of inlet pressure.
Background technology
Valve is the control unit in fluid delivery system, has cut-off, adjusting, water conservancy diversion, prevents adverse current, voltage stabilizing, shunting
Or the functions such as overflow pressure relief.For the valve of fluid control systems, from simplest shut-off valve to extremely complex robot control system(RCS)
Used in various valves, kind and specification are quite various.Valve can be used for controlling empty gas and water, steam, various corrosivity and be situated between
The flowing of the various types fluid such as matter, mud, oil product, liquid metal and radiating medium.The size of valve inlet pressure is to close
Envelope portion generates extremely important influence, and inlet pressure is easy greatly very much to generate erosion to sealing, and sealing is easily damaged.Commonly
Valve includes ball valve, existing ball valve include valve body, the valve deck being connected with valve body, the sphere being located in valve body, with sphere into
Valve seat, the valve rod being connected with sphere and the handle being turned on and off for control valve of row sealing.Existing ball valve cannot
Inlet pressure is enough adjusted, inner ball sealing surface is easy by the quick erosion of medium, short life, repair trouble.
Utility model content
Based on the above issues, the utility model aim be to provide it is a kind of it is simple in structure, inlet pressure is adjustable, long lifespan with
And the ball valve of good airproof performance.
In view of the above problems, providing following technical solution：A kind of adjustable ball valve of inlet pressure, including valve body and valve
Lid, the valve body include import, outlet and valve chamber, and the valve body is equipped with the adjusting for adjusting medium entrance pressure and fills
It sets, the regulating device includes the baffle being located in valve chamber and the screw rod that is located on valve body and is threadedly coupled with it, the spiral shell
Bar opposing flaps are rotatable, and the valve chamber inner wall is equipped with fixed seat, and the baffle is connected by hinged with fixed seat, the spiral shell
It is arranged with the seal receptacle being threadedly coupled with it on bar, filler is equipped between the seal receptacle and screw rod, is arranged on the screw rod
For by the pressing plate of packing seal, the pressing plate to be connect with screw flight, the screw tip is equipped with the hand being clasped with it
Wheel.
In above structure, valve rod is controlled by handwheel and is moved up and down, to which position of the control baffle in valve chamber reaches
Adjust the effect of inlet pressure.When inlet pressure is excessive, rotation hand wheel controls screw rod and drives baffle downward, to reduce pressure,
Well prevent ball seal face reduces maintenance rate by medium erosion to increase the service life of sphere.Work as import
When pressure is small, rotation hand wheel controls screw rod and drives baffle upward, avoids stopping the outlet of medium flow direction, be situated between to increase
The dynamic rate of mass flow.Seal receptacle is set, filler is set between seal receptacle and valve rod, then is fixed with pressing plate and can be good at preventing
Medium is flowed out by the junction of valve rod and valve body.
The utility model is further arranged to, and the valve body is equipped with annular groove compatible with seal receptacle.
In above structure, seal receptacle be entrenched in valve body it can connect more securely and seal receptacle and valve rod it
Between better tightness.
The utility model is further arranged to, and the baffle front end is in arc-shaped.
Using the above structure, the pressure that can preferably reduce import, prevents inlet pressure excessive and damages baffle.
The beneficial effects of the utility model：Compared to existing ball valve, the utility model is simple in structure, inlet pressure is adjustable,
Long lifespan and good airproof performance.Valve rod is controlled by handwheel to move up and down, to which position of the control baffle in valve chamber reaches
Adjust the effect of inlet pressure.When inlet pressure is excessive, rotation hand wheel controls screw rod and drives baffle downward, to reduce pressure,
Well prevent ball seal face reduces maintenance rate by medium erosion to increase the service life of sphere.

Specific implementation mode
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
A kind of ball valve of 11 pressure adjustable of import as shown in Figure 1, including valve body 1 and valve deck 2, the valve body 1 include
Import 11, outlet 12 and valve chamber 13, the valve body 1 is equipped with the regulating device 3 for adjusting 11 pressure of medium entrance, described
Regulating device 3 includes the baffle 31 being located in valve chamber 13 and the screw rod 32 for being located on valve body 1 and being threadedly coupled with it, the spiral shell
32 opposing flaps 31 of bar are rotatable, and 13 inner wall of the valve chamber is equipped with fixed seat 4, and the baffle 31 passes through hinged and fixed seat 4
It is connected, the seal receptacle 5 being threadedly coupled with it is arranged on the screw rod 32, filler is equipped between the seal receptacle 5 and screw rod 32
