Abstract
The utility model discloses a working oil-way valve block for a static pressure vehicle-mounted fork truck, which comprises a valve block. Valve block blanks are successively subject to the forging with No.45 steel, the machining of drilling, milling and clamping and the surface galvanizing treatment to form the valve block of the utility model. The plurality of surfaces of the valve block are successively opened with a plurality of connection oil ports. The top and the bottom of the valve block are opened with bolt holes. The valve block is compact in structure and high in reliability, which effectively lowers the complexity of the hydraulic vehicle-mounted fork truck pipeline and improves the assembly and maintenance performance thereof.
Description
Technical field
The utility model relates to a kind of valve piece, mainly is that a kind of static pressure is with car fork truck working oil path valve piece.
Background technology
With the car fork truck is a kind of High Performance field work fork truck of hydrostatic drive, because the fork lift truck structure space is narrower and small, hoist in the work system and inclination is double-acting cylinder, the oil circuit more complicated, the rail assembling brings very big difficulty, in order to reduce the I﹠ M difficulty of oil pipe, need the working oil path valve piece of a kind of all-hydraulic fork truck special use of design.
The utility model content
Technical problem to be solved in the utility model provide a kind of static pressure with the car fork truck with working oil path valve piece, it has increased and has hoisted and the assembly space of the oil circuit that tilts, and has reduced the complexity of oil line pipe, has improved the I﹠ M performance of oil circuit.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of static pressure with working oil path valve piece, includes the valve piece with the car fork truck, upper and lower hydraulic lock A hydraulic fluid port, the hydraulic lock B hydraulic fluid port of having successively of the leading flank of described valve piece, and described hydraulic lock A hydraulic fluid port, hydraulic lock B hydraulic fluid port all respectively have two hydraulic fluid ports; The left surface of described valve piece has left side hydraulic fluid port under hydraulic fluid port on hydraulic fluid port on the cylinder, the left bank cylinder, the left bank cylinder, the left side hydraulic fluid port under the cylinder that hoists that hoists; The position of the corresponding left surface hydraulic fluid port of the right flank of described valve piece has right side hydraulic fluid port under hydraulic fluid port on hydraulic fluid port on the cylinder, the right bank cylinder, the right bank cylinder, the right side hydraulic fluid port under the cylinder that hoists that hoists; The mutual cooresponding hydraulic fluid port of described and arranged on left and right sides is connected.The top and the bottom of described valve piece have bolt hole.
Described valve piece adopts the 45# forging to make by valve piece blank and forms, mill, bore, clamp machinework after the forging more successively, and zinc-plated processing is carried out on last surface.
The packaged timing of described valve is connected with vehicle frame by bolt by bent plate, and corresponding hydraulic fitting and hydralic hose are installed on described each hydraulic fluid port of valve piece.
Left side hydraulic fluid port on the cylinder, the right side hydraulic fluid port on the cylinder that hoists about hydraulic fluid port connects on the cylinder that hoists that hoists in the utility model; On the right bank cylinder on hydraulic fluid port, the left bank cylinder hydraulic fluid port be connected with hydraulic fluid port on the cylinder that tilts; Under the right bank cylinder under hydraulic fluid port, the left bank cylinder hydraulic fluid port be connected with hydraulic fluid port under the cylinder that tilts; The right side hoist hydraulic fluid port under the cylinder, a left side hoist under the cylinder hydraulic fluid port with about hoist that hydraulic fluid port is connected under the cylinder; Wherein hydraulic lock A hydraulic fluid port, hydraulic lock B hydraulic fluid port are connected with A, the B mouth of same hydraulic lock respectively; Other hydraulic lock A hydraulic fluid port, hydraulic lock B hydraulic fluid port are connected with A, the B hydraulic fluid port of another hydraulic lock.
The utility model valve piece adopts the 45# forging to make and forms good pressure-resistant performance; The utility model appropriate design valve piece internal holes, reduce hydraulic joint quantity, reduce the pipeline complexity, appropriate design valve piece hydraulic fluid port opening direction reduces the oil pipe assembly difficulty, improves the oil pipe assembly space;
On the valve piece appropriate design tapped bore of four M6, can be simple and effective assemble with door frame, good reliability installs, safeguards simple and convenient.
The utility model has the advantages that:
The utility model compact conformation, good reliability, simple and convenient with the assembling of door frame, it is little to take up room, and pipeline is clear, can effectively reduce all-hydraulic complexity with car fork truck pipeline, has improved the I﹠ M performance with car fork truck hydraulic tubing.
