Abstract
Basis is the most novel discloses a kind of novel balance control valve, including being provided with the spherical valve body of fluid inlet and outlet, also include that hull shape spool, hull shape valve core rotation are connected in the runner of spherical valve body, the bottom of hull shape spool is installed with fixing axle, and the top of hull shape spool is fixedly connected with valve rod；Spherical valve body top is fixed with valve gap；Hull shape spool is provided with the sphere sealed, and the hull shape spool of spherical symmetry position is provided with shunting muscle, for two flow regulating orifices communicated on hull shape spool, between sphere and shunting muscle；Sphere both sides of the edge are respectively equipped with and are extended with cambered surface projection, and the edge of arc convex is irregular curve；The seal valve seat coordinated with ball face sealing it is provided with inside feed liquor runner.Basis is the most novel to be provided the benefit that: throughput is big, and range of accommodation is wide, is conducive to combining executor and precisely measures and regulate；Additionally, spool is rotating when, the arc convex which is provided with can play transitional function, it is to avoid too much abradable seal valve seat, extends the service life of control valve.
Description
Technical field
Basis is the most novel relates to a kind of novel balance control valve, belongs to heating apparatus and controls valve field.
Background technology
At present, the cardinal principle of existing spherical balance control valve is that valve rod drives valve core rotation, and its valve core structure is usual
For being provided with the spheroid of through hole, the when that the through hole on spool communicating with the fluid inlet and outlet on spherical valve body, fluid passes through.This
Structure has Railway Project: 1, fluid throughput is little；2, range of accommodation is little, is unfavorable for accurately controlling；3, the most stuck after fouling.
Summary of the invention
In order to overcome drawbacks described above, this kind of novel balance control valve of novel offer.
To achieve these goals, this novel technical scheme is: a kind of novel balance control valve, including being provided with fluid
The spherical valve body imported and exported, also includes that hull shape spool, described hull shape valve core rotation are connected in the runner of spherical valve body, hull shape valve
The bottom of core is installed with fixing axle, and fixing axle is installed on spherical valve body, and the top of described hull shape spool is fixedly connected with
Valve rod；Described spherical valve body top is fixed with valve gap, and valve rod is installed in valve gap；Described hull shape spool has been provided with sealing and has made
Sphere, the hull shape spool of spherical symmetry position is provided with shunting muscle, for communicating on hull shape spool, between sphere and shunting muscle
Two flow regulating orifices；Described sphere both sides of the edge are respectively equipped with and are extended with cambered surface projection, and the edge of arc convex is not for advise
Then curve, the radius of arc convex is slightly less than spherical radius；It is provided with arc recessed inside the runner feed liquor direction of described spherical valve body
Groove, is provided with the seal valve seat coordinated with ball face sealing in annular groove, be provided with hollow locking device outside seal valve seat.
Further, described hollow locking device includes plate washer, wave washer and open washer.
Basis is the most novel to be provided the benefit that: throughput is big, and range of accommodation is wide, is conducive to combining executor and precisely measures
And regulation；Additionally, spool is rotating when, the arc convex which is provided with can play transitional function, it is to avoid too much abrasion
Seal valve seat, extends the service life of control valve.
Accompanying drawing explanation
Fig. 1 is the structural representation that this is novel.
Detailed description of the invention
It is described further the most novel below in conjunction with specific embodiment.
As it is shown in figure 1, a kind of novel balance control valve, including being provided with the spherical valve body 1 of fluid inlet and outlet, also include shell
Shape spool 2, described hull shape spool 2 is rotationally connected with in the runner of spherical valve body 1, and the bottom of hull shape spool 2 is installed with
Dead axle 3, fixing axle 3 is installed on spherical valve body 1, and the top of described hull shape spool 2 is fixedly connected with valve rod 4；Described globe valve
Body 1 top is fixed with valve gap 5, and valve rod 4 is installed in valve gap 5；Described hull shape spool 2 is provided with the sphere sealed
201, the hull shape spool 2 of sphere 201 symmetric position be provided with shunting muscle 202, on hull shape spool 2, sphere 201 and shunting muscle 202
Between for two flow regulating orifices 203 communicating；Described sphere 201 both sides of the edge are respectively equipped with and are extended with cambered surface projection 204, arc
The edge of shape projection 204 is irregular curve, and the radius of arc convex 204 is slightly less than sphere 201 radius；Described spherical valve body
It is provided with arc groove 6 inside runner feed liquor direction, is provided with in annular groove 6 and seals, with sphere 201, the seal valve seat 7 coordinated, close
It is provided with hollow locking device 8 outside envelope valve seat 7.Hollow locking device 8 includes plate washer, wave washer and open washer.
The when of actually used, executor above valve rod 4, can be connected.
This most novel technical scheme is not limited to the restriction of above-mentioned specific embodiment, and every technical scheme the most novel according to basis is done
The technology deformation gone out, within each falling within this novel protection domain.
