Abstract
A hydraulic winch motor balancing valve with the pressure protecting function belongs to a balancing valve. The hydraulic winch motor balancing valve comprises a basic valve and a relief valve connected on the outlet of the basic valve, the basic valve and the relief valve are integrated, the basic valve comprises an one-way balancing valve, a valve body and a shuttle valve, wherein the one-way balancing valve and the shuttle valve are located in the valve body, one end of the one-way balancing valve is a port C, the other end thereof is connected with the shuttle valve and is a port A, the other end of the shuttle valve is a port D and a port B, the middle part of the shuttle valve penetrates though the relief valve and is a port F. The relief valve is integrated on the basic valve, namely balancing valve, by adjusting the pressure of the outlet of the relief valve, the oil pressure at the oil outlet of a brake can be controlled. The utility model has the advantages that the structure is compact, the cost is saved and the installation space is reduced, the oil pressure at the oil outlet of the brake is adjustable, the service life of the control valve is prolonged, and the reliability of the product is improved.
Description
Technical field
The utility model relates to a kind of equilibrium valve, particularly a kind of hydraulic wireline winch motor equilibrium valve with the pressure protect function.
Background technique
At present, on the hydraulic wireline winch motor, use traditional equilibrium valve that it is controlled, when using equilibrium valve control to press winch motor, cause does not limit the pressure of equilibrium valve break hydraulic fluid port, the working connection oil pressure equates with the oil pressure that enters into break, the oil pressure pressure of working connection causes dish spring in the break by conquassation than Da Yi, causes whole break destroyed.When running into this situation, winch production firm can only frequently change the dish spring, wastes time and energy.
The model utility content
The utility model purpose is that a kind of hydraulic wireline winch motor equilibrium valve that can control the band pressure protect function of working connection oil pressure will be provided.
The technical solution of the utility model is: this hydraulic wireline winch motor equilibrium valve comprises basic valve and reduction valve, connects reduction valve in the outlet of basic valve, and basic valve and reduction valve are structure as a whole.
Described basic valve comprises unidirectional equilibrium valve, valve body and shuttle valve, unidirectional equilibrium valve, and shuttle valve all be positioned at valve body, unidirectional equilibrium valve one end is the C port, the other end is connected with shuttle valve and is the A port, the other end of shuttle valve is D end and B port, and the centre of shuttle valve is the F port by reduction valve.
Beneficial effect: owing to adopted such scheme, be integrated reduction valve on the equilibrium valve,, realize control, reached the novel purpose of this reality to break hydraulic fluid port oil pressure by regulating the outlet pressure of reduction valve at basic valve.
Advantage: the utility model compact structure, both provided cost savings, saved installing space again, controller hydraulic fluid port oil pressure is adjustable, has prolonged the working life of control valve, has improved reliability of products.
Description of drawings
Fig. 1 is a structural drawing of the present utility model.
Among the figure, 1, unidirectional equilibrium valve; 2, valve body; 3, shuttle valve; 4, reduction valve.
Embodiment
Embodiment 1: this hydraulic wireline winch motor equilibrium valve comprises basic valve and reduction valve 4, connects reduction valve in the outlet of basic valve, and basic valve and reduction valve are structure as a whole.
Described basic valve comprises unidirectional equilibrium valve 1, valve body 2 and shuttle valve 3, unidirectional equilibrium valve 1, and shuttle valve 3 all be positioned at valve body 2, unidirectional equilibrium valve 1 one ends are the C port, the other end is connected with shuttle valve 3 and is the A port, the other end of shuttle valve is D end and B port, and the centre of shuttle valve is the F port by reduction valve.
Working connection: the high pressure oil of A mouth or B mouth directly drives the motor rotation, and flows back to fuel tank from B mouth or A mouth; The break control oil channel: the high pressure oil of working connection enters reduction valve 4 and carries out step-down by shuttle valve 3, and the hydraulic oil after the step-down is from opening the break on the speed reducer after the F mouth flows out.
Promptly integrated reduction valve on traditional equilibrium valve basis by regulating the outlet pressure of reduction valve, is realized the control to break hydraulic fluid port oil pressure.
