Abstract
The invention discloses a valve element structure for a numerical control flow valve. The valve element structure is characterized by comprising a rotor shaft, a through cavity is formed inside the rotor shaft, a reset spring is arranged inside the through cavity, a bayonet used for being clamped to a valve element is arranged on a port of the valve element, a valve element rod is clamped in the bayonet, and a steel ball is arranged between the valve element rod and the reset spring. In actual use, the valve element structure can be adjusted and controlled conveniently and accurately, can be protected and is long in service life.
Description
Technical field
The present invention relates to the valve core structure on a kind of numerical control flux valve.
Background technique
Along with the development of society, the progress of science and technology, growth in the living standard, simultaneously owing to being becoming tight energy day, energy-conservation aspect obtains very high attention.As the flow control element in control system, it is large that numerical control flux valve has flow adjustment range, and control accuracy is high, is applicable to the advantages such as intelligent control, applies more and more extensive.The quality of numerical control flux valve performance directly has influence on operation conditions and the energy-saving effect of whole system.At present three aspects are mainly concentrated on to the research of numerical control flux valve: testing property, controlling method and application study.And it is less for the research of the valve core structure self performance improved on numerical control flux valve.
The kind of numerical control flux valve is a lot, structure is also mostly different, but the form of its throttle structure is then similar, mainly cone valve structure, we know that throttle structure directly determines Flow characteristics, and its linearity of the Flow characteristics of cone valve structure is undesirable, namely when condition certain (pressure reduction is certain), flow and aperture are not proportional relation, but become curved line relation, close to quadratic curve.One of them affected factor is valve core structure, so this current spool needs to be improved.
Summary of the invention
The object of the invention is the valve core structure in order to provide on a kind of numerical control flux valve, regulable control is accurately convenient, protects whole valve core structure, life-saving simultaneously.
For achieving the above object, technological scheme of the present invention is:
Valve core structure on numerical control flux valve, it is characterized in that: comprise rotor shaft, the inside of described rotor shaft forms cavity, Returnning spring is provided with in described cavity inside, port is provided with the bayonet socket connected for spool buckle, in described bayonet socket, buckle one valve core rod, is provided with steel ball between described valve core rod and described Returnning spring.
The present invention is done further preferably, is provided with hexagonal screw at the top end of described rotor shaft.
Do further preferably the present invention, be provided with a disrance sleeve at the top end of described rotor shaft, described disrance sleeve is cylindric, and inner hollow, lower end is open-mouth end, and inwall is provided with a longitudinal register bar.
The present invention is done further preferably, is provided with outside thread in the upper portion of described rotor shaft outer wall.
Do further preferably the present invention, described valve core rod comprises valve core, and the end of described valve core is provided with outer bulge loop, and lower end outer wall is provided with annular wall, and bottom terminal ends is provided with arc-shaped side.In this structure, arranged by bulge loop outside end, can well be buckled in the cavity of rotor shaft inside, arranging of annular wall can contact with valve body internal passage in addition, forms sealing, so can reduce sealing gasket, simplified structure, improves overall structural behaviour.
Compared with prior art, beneficial effect of the present invention:
Valve core in the present invention is the regulative mode that is flexible coupling, namely rotor shaft is comprised, the inside of described rotor shaft forms cavity, Returnning spring is provided with in described cavity inside, port is provided with the bayonet socket connected for spool buckle, buckle one valve core rod in described bayonet socket, steel ball is provided with between described valve core rod and described Returnning spring, this Placement can prevent from rotor shaft axial seal force when being in closed condition from crossing the static friction power that the contact conical surface of ambassador's valve core rod and valve body produces being greater than the torque of motor and making motor by stall effectively, can also prevent in addition after valve core rod is in closed condition and follow axis of rotation, and make the sealing surface of valve body and valve core rod produce wearing and tearing.
As from the foregoing, regulable control of the present invention is accurately convenient, protects whole valve core structure, life-saving simultaneously.
In order to explain technological scheme of the present invention further, below by specific embodiment, the present invention will be described in detail.
Accompanying drawing explanation
Fig. 1 is cross-sectional structure schematic diagram of the present invention.
