Abstract
The utility model relates to a rotation control type multi-way valve. The multi-way valve is composed of an operation handle, a valve body, a hydraulic controlled plunger, a one-way valve, a centering spring, a location cap, a safety valve, a control valve core, a location disc, a first radial hole, a second radial hole, an axial hole and an undercutting groove. The control valve core is mounted on the valve body, and the operation handle is mounted on the control valve core. The hydraulic controlled plunger, the one-way valve, the safety valve and the location disc are mounted on the valve body respectively. The centering spring is sleeved on the control valve core, and the location cap is arranged on the outside of the centering spring. The first radial hole, the second radial hole, the axial hole and the undercutting groove are formed in the control valve core respectively. According to the multi-way valve, the structure is simple, and the design is reasonable; a hydraulic lock is used, the opening and the closing of the hydraulic lock are controlled through hydraulic force provided by the system, the hydraulic lock cannot be opened no matter how the operation handle is pulled when a main machine stops operating, and the load falling caused by the mistaken operation after stopping is prevented, so that the multi-way valve is safe and convenient to use and operate, stable in operation performance, low in failure rate and high in operation efficiency.
Description
Technical field
The utility model relates to a kind of revolution control formula multi-way valve.
Background technique
At present, the one-way valve of existing revolution control formula multi-way valve is realized machinery by spool and is controlled, and after main frame quits work, pulls operating grip and can make one-way valve opens, cause operating load to fall, harm personal safety, in addition, when work, rate of fault is high, while automatically reseting, spool is easily stuck, oil cylinder easily sinks, and maintenance difficult affects working efficiency.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming, a kind of revolution control formula multi-way valve is provided, it has mainly solved the one-way valve of existing revolution control formula multi-way valve and has realized machinery control by spool, after main frame quits work, pull operating grip and can make one-way valve opens, the problems such as while causing operating load fall and automatically reset, spool is easily stuck, and oil cylinder easily sinks, maintenance difficult.The purpose of this utility model be achieved in that a kind of revolution control formula multi-way valve by: operating grip, valve body, hydraulic control plunger, one-way valve, centralizing spring, locating cover cap, safety valve, control spool, positioning disk, the first radial hole, the second radial hole, axial bore, undercut groove form.Controlling spool is arranged on valve body, operating grip is arranged on to be controlled on spool, hydraulic control plunger, one-way valve, safety valve, positioning disk are arranged on respectively on valve body, centralizing spring is sleeved on to be controlled on spool, locating cover cap is equipped with in the outside of centralizing spring, controls on spool and is respectively equipped with the first radial hole, the second radial hole, axial bore, undercut groove.This product structure is simple; reasonable in design; the keying of the hydraulic coupling control hydraulic lock that its employing hydraulic lock is provided by system, after main frame quits work, in any case pull operating grip; hydraulic lock can not be opened; avoid the load that after shutting down, misoperation produces to fall, used easy-to-operate, stable work in work; failure rate is low, working efficiency is high.
