Description
Technical field:
The utility model relates to the valve field, relates in particular to a kind of banked direction control valves.
Background technology:
The hydraulic support banked direction control valves always as the Hydraulic Elements of hydraulic support column control, plays the effect of control column up-down, plays a part very important in the fully mechanized mining supporter loop.Traditional fluid-control one-way valve seal mostly is plastics or valve pad soft seal, and life and reliability is too low, complex structure, and maintenance efficiency is low, has a strong impact on to combine carrying out smoothly of adopting.We release the hydraulic control one-way valve of the integral plugged formula core assembly structure of the hard sealing of a kind of metal loop wire through independent research, have well solved the problem that the conventional valve life-span is low, maintenance is complicated, have greatly improved production efficiency.The safety valve that uses at present is because most of straight unloading way that adopts; adopt single O RunddichtringO sealing; spool moves the off-load aperture O RunddichtringO that often rubs back and forth makes sealing ring damaged easily; safety valve lost efficacy; traditional safety valve spring seat can not be avoided the problems such as spring dislocation that radial action causes in addition; may cause the Spring Card other problems of waiting indefinitely, also have spring in unprotected situation, to be subjected to the problems such as hydraulic fluid corrosion impact life-span.Therefore imagination provides a kind of banked direction control valves to solve this problem.
The utility model content:
The purpose of this utility model just provides a kind of banked direction control valves, solve safety valve and lost efficacy and low, complex structure of valve life-span, maintenance efficiency high problem.
The technical solution adopted in the utility model is:
A kind of banked direction control valves, comprise the oil-feed body, be provided with oil duct in the oil-feed body, left side, oil duct upper end is equipped with one-way valve seat, and the one-way valve seat left end is equipped with swivel union, spring and steel ball are installed in the one-way valve seat, the one-way valve seat right-hand member is equipped with guiding valve, and the shunting spring is installed between guiding valve and the one-way valve seat, and the guiding valve right-hand member is equipped with throttling element, the throttling element right-hand member is equipped with plug screw, and it is external that the plug screw right-hand member stretches out oil-feed; Right side, oil duct lower end is equipped with spill valve, left side, oil duct lower end is equipped with safe spool, safe spool right-hand member is equipped with safety valve spring, safe spool left end is equipped with emergency valve seat, the emergency valve seat left end is equipped with screw, screw passes the shunting safety valve cover plate that is installed on the outer wall of the oil-feed body left side, and screw stretches out on the part of shunting the safety valve cover plate nut and spring washer are installed.
Described oil-feed body upper end is provided with oil-in, and oil-in and oil duct are interconnected.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is by being equipped with swivel union at the one-way valve seat left end, spring and steel ball are installed in the one-way valve seat, the one-way valve seat right-hand member is equipped with guiding valve, the shunting spring is installed between guiding valve and the one-way valve seat, and the guiding valve right-hand member is equipped with throttling element, and the throttling element right-hand member is equipped with plug screw, it is external that the plug screw right-hand member stretches out oil-feed, simple in structure, high life, easy to maintenance.
