Description

Loader fluid-link steering stop valve
Technical field
The utility model relates to a kind of fluid-link steering stop valve.Be installed between the commutator and switching valve of loader, in order to the steering angle of control loader.Belong to the hydraulic control component technical field.
Background technique
Conventional loader is a steering angle of controlling loader with the dead location of impact block when realizing turning to, and it exists ovdersteering may make the hidden danger of the danger of loader overturning.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and can make turning to of loader control flexible and safe loader fluid-link steering stop valve.
The purpose of this utility model is achieved in that a kind of loader fluid-link steering stop valve, comprises valve body, valve rod, one-way valve spool, check valve spring, housing screw, spring seat, big spring, lid, resilient dust boot and push rod,
Described valve rod left end is inserted in the valve body, the valve rod left end shaft is to being provided with valve opening, and one-way valve spool and check valve spring place in this valve opening, and the nose end of described valve opening is provided with housing screw and tightens, described check valve spring is embedded between one-way valve spool and the housing screw
Described spring seat is connected in the left end of valve body, and big spring places in the spring seat, and closely contacts with housing screw left part in the valve body,
Described valve rod right-hand member stretches out outside the valve body, and lid is placed on the valve rod, and fixedlys connected with the right-hand member of valve body,
Described resilient dust boot cover places the right-hand member of valve rod, and with push rod resilient dust boot and valve rod right-hand member is tightened, and the push rod right-hand member exposes outside the resilient dust boot,
Offer two oil circuit hole A mouths and B mouth on the described valve body, the commutator of A mouth tipping carrier aircraft, the switching valve of B mouth tipping carrier aircraft.
The utility model is controlled the switching of switching valve by stretching of push rod of control.When valve rod was in meta, the A mouth was in channel status to the B mouth, the function that realization turns to, and when valve stem depressions 2.5mm, the logical B mouth of A mouth is closed, and loading machine steering stops.After stopping bump, reset by big spring.
To sum up, the utility model can make turning to of loader control flexibly and safety.
