Abstract
The utility model relates to a partial regulating ball valve, which comprises a valve body and a valve stem, wherein the a ball is arranged inside the valve body, a valve seat is disposed between the ball and the valve body, the valve seat is connected with the valve body through a disc spring, the valve stem penetrates through the valve body to be connected with the valve body and can drive the ball to rotate at an angle ranging from 0 degree to 90 degrees, and the ball is equipped with a throttling hole. The partial regulating ball valve has the advantages that the throttling hole arranged on the ball can firstly regulate fluid flow or pressure in the opening process of the valve, and then the valve can still lead the fluid flow to be unblocked when the valve is opened continuously, and the partial regulating ball valve is particularly suitable for system piping requiring both pressure or flow regulation and unblocked working condition.
Description
Technical field
The utility model relates to a kind of ball valve, relates in particular to a kind of local modulation ball valve.
Background technique
At present, ball valve on the market generally comprises valve body, valve rod, spheroid, spring, valve seat, seal element is spheroid and valve seat, spheroid becomes sphere to cooperate with valve seat, spheroid is that rotating shaft can be done 90 degree rotations with the valve rod in valve body, to open and close valve body (pipeline) passage, unimpeded and prevention channel media flows.But this ball valve has only the opening and closing two states, can not be used for local modulation fluid flow and pressure.
The model utility content
The purpose of this utility model provides a kind of local modulation ball valve, has solved the problem that existing ball valve can not be used for local modulation fluid flow and pressure.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of local modulation ball valve comprises valve body and valve rod, and described valve inner is provided with spheroid, is provided with valve seat between valve body and the spheroid, and valve seat is connected with valve body by the dish spring; Described valve rod passes that valve body is connected with spheroid and valve rod can to drive spheroid be that rotating shaft is done the 0-90 degree and rotated with the valve rod, described spheroid is provided with throttle orifice.
The beneficial effects of the utility model are: the throttle orifice on the spheroid can first regulated fluid flow or pressure in the opening process of valve, continuing to open late gate at valve still can complete unimpeded fluid flow, not only needing to be particularly suitable for pressure or Flow-rate adjustment but also to need using on the system pipeline of operating mode of Channel Group.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the sectional drawing of the described local modulation ball valve of the utility model embodiment;
Fig. 2 is the closed condition schematic representation of the described local modulation ball valve of the utility model embodiment;
Fig. 3 is the adjustment state schematic representation of the described local modulation ball valve of the utility model embodiment.
Among the figure:
1, valve body; 2, valve rod; 3, spheroid; 4, valve seat; 5, dish spring; 6, throttle orifice.
Embodiment
As Figure 1-3, the described a kind of local modulation ball valve of the utility model embodiment comprises valve body 1 and valve rod 2, described valve body 1 inside is provided with spheroid 3, be provided with valve seat 4 between valve body 1 and the spheroid 3, valve seat 4 is connected with valve body 1 by dish spring 5, and the elastic force of dish spring 5 is close to spheroid 3 and valve seat 4; Described valve rod 2 passes that valve body 1 is connected with spheroid 3 and valve rod 2 can to drive spheroid 3 be that rotating shaft is done the 0-90 degree and rotated with valve rod 2, spheroid 3 is provided with throttle orifice 6.
The described a kind of local modulation ball valve of above the utility model embodiment, spheroid 3 cooperate with valve seat 4 can make valve be in full closing state, and rotation valve rod 2, fluid flow through the throttle orifice 6 on the spheroid 3, and fluid has been reduced hydrodynamic pressure by throttle orifice 6 shunting decompressions; It is that rotating shaft is rotated with valve rod 1 that rotation valve rod 1 drives spheroid 3, and the quantity that fluid flows through the throttle orifice 6 on the spheroid 3 changes, and fluid flow also changes thereupon; Being rotated further valve rod 1 drive spheroid 3 again is that the rotating shaft rotation can make valve open fully with valve rod 1, and fluid unimpededly flows through spheroid.
