Abstract

The utility model relates to a throttle governing ball valve, including a valve body, a valve stem, a sphere and a valve seat, wherein the sphere is disposed within the valve body, the valve seat is disposed between the sphere and the valve body, the valve seat body is connected with the valve through a disc spring, the valve stem passing through the valve body is connected with the sphere, the utility model is characterized in that: the sphere hole of the sphere is disposed with a throttle orifice therein, and the outlet of the sphere hole is a curved type flow crossing. The beneficial effect of the throttle governing ball valve is that: the utility model can adjust the fluid flow rate and reduce the fluid pressure, and is especially suitable to be used for the system and pipeline of the condition that the pressure and flow adjustment are needed.

Description

Ball valve is regulated in a kind of throttling

Technical field

The utility model relates to a kind of ball valve, relates in particular to a kind of throttling and regulates ball valve.

Background technique

Existing ball valve generally comprises valve body, valve rod, spheroid, spring, valve seat, seal element is spheroid and valve seat, and spheroid becomes sphere to cooperate with valve seat, and 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, stop channel media to flow.The deficiency of existing this ball valve is: can not be used for regulated fluid flow and pressure.

The model utility content

The purpose of this utility model provides a kind of throttling and regulates ball valve, has solved the problem that existing ball valve can not be used for regulated fluid flow and pressure.

The purpose of this utility model is to be achieved through the following technical solutions:

Ball valve is regulated in a kind of throttling, comprise valve body, valve rod, spheroid and valve seat, wherein spheroid is arranged in the valve body, valve seat is located between spheroid and the valve body, is connected with the dish spring between valve seat and the valve body, and the elastic force of dish spring is close to spheroid and valve seat, valve rod passes valve body and is connected with spheroid, it is that the rotation of 0-90 degree is done in rotating shaft with the valve rod that valve rod can drive spheroid, is provided with restricting orifice in the ball hole of described spheroid, and ball hole exits place is a curved runner mouth.

The beneficial effect that ball valve is regulated in throttling described in the utility model is: it is long-pending with the regulated fluid flow that ball hole exits place curved runner mouth can change fluid cross-section, and can by the restricting orifice convection cell successively shunting decompression be particularly suitable for using in the system, pipeline in the operating mode that needs pressure and Flow-rate adjustment to reduce hydrodynamic pressure.

Fig. 2 is the spheroid generalized section that ball valve is regulated in the described throttling of the utility model embodiment;

Fig. 3 is the spheroid left view that ball valve is regulated in the described throttling of the utility model embodiment.

Among the figure:

1, valve rod; 2, valve body; 3, spheroid; 4, valve seat; 5, dish spring; 6, restricting orifice; 7, curved runner mouth

Embodiment

With embodiment the utility model is described in further detail with reference to the accompanying drawings below.

As Figure 1-3, ball valve is regulated in the described throttling of the utility model embodiment, comprise valve body 2, valve rod 1, spheroid 3, valve seat 4, dish spring 5, restricting orifice 6, spheroid 3 is positioned at valve body 2, be provided with valve seat 4 between spheroid 3 and the valve body 2, be connected with dish spring 5 between valve seat 4 and the valve body 2, the elastic force of dish spring 5 is close to spheroid 3 and valve seat 4, valve rod 1 passes valve body 2 and is connected with spheroid 3, it is that the rotation of 0-90 degree is done in rotating shaft with valve rod 1 that valve rod 1 can drive spheroid 3, be provided with restricting orifice 6 in the ball hole of described spheroid 3, ball hole exits place is a curved runner mouth 7.

When fluid flows through spheroid 3, the restricting orifice 6 in the ball hole by convection cell successively shunting decompression reduce hydrodynamic pressure; Rotating sphere 3 makes the ball hole be fixed in different azimuth, and the size of ball hole inlet is just different, thereby has changed the sectional area of fluid, and fluid flow promptly can change thereupon; When fluid flowed out spheroid 3, the curved runner mouth 7 at ball hole exits place further fluid flow was regulated.
