Left end be equipped with vent valve, the top of vent valve is equipped with a gas outlet, when ball valve hypertonia, is completed by vent valve automatic
It deflates.It is installed for the first time in hydraulic system or hydraulic pipeline is unavoidably mixed into air when usually security maintenance, in the four way ball valve
In devise two vent valves, in the case where the blocking of first vent valve or damage, second vent valve is also ensured that normally
Work.In order to the gas in better discharge tube.It is equipped with a handle on the upper top of valve rod, handle tip is set on position
There are taper knob, operation more comfort and convenient.
When being in initialization position, i.e. four way ball valve does not commutate the four way ball valve of the ball valve, when C mouthfuls of oil inlets, liquid
Pressure oil enters left side oil circuit by four way ball valve, then enters A mouthfuls by ball valve, and system oil return passes through B mouthfuls, ball valve and four way ball valve
Communicate with D, if the right and left oil circuit is mixed into air, be directly exhausted by E mouthfuls, F mouthfuls again, exhaust complete can E mouthfuls,
F mouthfuls of cut-in pressure tables show the operating pressure of two oil circuits；When four way ball valve is in commutation position, when C mouthfuls of oil inlets, working oil is from C
Mouth enters right side oil circuit, then enters B mouthfuls by ball valve, and A oral fluid pressure oil then passes through ball valve and four way ball valve enters D mouthfuls, thus
Realize the executive component commutation function in hydraulic system, during the work time if there is pressure fluctuation or hydraulic shock, then
It releases again, when work is completed, first closes ball valve, realize system oil return, reduce operating power consumption, improve the work of Hydraulic Elements
Make the service life.
The beneficial effects of the utility model are: this ball valve can effectively control four valve interfaces, hydraulic oil is closed or
Output, solves ball valve, and advanced design, structure be simple, easy-to-operate.The ball valve design two is put
Air valve, if hydraulic pressure is excessively high, can gas in effective discharge tube, prevent pipeline burst, accomplish safety in production, using the longevity
Order long, easily operated and maintenance.
