Description
Technical field
The present invention relates to a kind of hydraulic valve technical field, more particularly to a kind of ball valve with vibrationproof valve element.
Background technology
For hydraulic valve as the control element in hydraulic system, its function is to control flow direction, the pressure of liquid in hydraulic system
And flow, so as to for the operating mechanism of hydraulic actuating mechanism and its driving provide the required direction of motion, movement velocity, rotating speed and
Thrust, torque etc..Ball valve is the hydraulic valve that a kind of valve element is shaped as ball shape structure, is existed in the form of poppet, extensive use
In the hydraulic valves such as choke valve, overflow valve, inserted valve, electro-hydraulic proportional flow valve and pilot valve, but in actual use process
Middle discovery, when hydraulic system is opened and is run, the problem of valve element generation radial vibration of ball valve be present, valve element occurs radially to shake
Dynamic the problems such as will causing air pocket, noise, flow pulsation, this can not only influence the performance of hydraulic valve, while also can be to whole liquid
Pressure system has undesirable effect, or even causes system to be trembled, therefore directly affects the operating efficiency of hydraulic system, and reduces liquid
Press the service life of element.
The content of the invention
The problem of for being proposed in above-mentioned background technology, present invention aims at provide a kind of ball with vibrationproof valve element
Valve, by setting up guide rod in ball valve core front end, so as to play a part of preventing valve element from radial vibration occurs.
To achieve the above object, the present invention proposes following technical scheme：
A kind of ball valve with vibrationproof valve element, including：Spring base, spring, valve pocket, guide rod, oil suction chamber, ball valve core, valve body,
The ball valve core, spring and spring base are in the valve pocket, wherein the spring one end is against the end of the spring base
On face, and in the horizon bar insertion spring of spring base, the other end of the spring is against on the end face of the ball valve core, and ball
In the horizon bar insertion spring of valve core, the rear end of the guide rod and the sphere of the ball valve core connect into an entirety,
Slided in the oil suction chamber front end of the guide rod.
As currently preferred technical scheme, the front-end position of the valve body is provided with opening, and with the oil suction chamber phase
It is logical, it is oil inlet, the centre position of the valve body is provided with opening, and is communicated with the valve pocket, is oil-out.
As currently preferred technical scheme, the sphere diameter of the ball valve core is straight more than the section of the oil suction chamber
Footpath.
As currently preferred technical scheme, the periphery of the guide rod front end connects with the oil suction chamber wall sliding
Touch.
As currently preferred technical scheme, the elongated segment diameter of the guide rod is straight less than the guide rod front end
Footpath.
As currently preferred technical scheme, length of spring when not by external force is more than the ball valve core
Horizontal pole length and the spring base horizontal pole length and.
Compared with prior art, the present invention has the advantages that：A kind of ball valve with vibrationproof valve element is provided, passed through
It is provided with the ball valve core of guide rod, it is possible to increase stability when valve element is opened and when working, prevent ball valve core
Radial vibration, reduce the pulsation of hydraulic oil, improve the performance of hydraulic ball valve, extend the service life of hydraulic ball valve.
