Abstract
The invention discloses a dual-oil-circuit pressure reducing valve of rubber molding equipment. The dual-oil-circuit pressure reducing valve of the rubber molding equipment comprises a valve body and a valve core; the valve core is arranged at the central part in the valve body; an oil intake cavity is arranged at the central part of the valve core and an oil discharge cavity is arranged in the valve body at the tail end of the valve core; an oil discharge port is formed in a valve body chamber positioned at the outer side of the valve core, is connected with a pressure reducing diversion oil pipe and is connected with an oil discharge cavity through the diversion oil pipe; and the pressure reducing diversion oil pipe is provided with a switch valve sheet. The dual-oil-circuit pressure reducing valve of the rubber molding equipment provided by the invention has the beneficial effects that the pressure reducing diversion oil pipe is added between the oil discharge cavity and the oil discharge port, and the simple switch valve sheet is arranged outside, during the process of the experiment of keeping oil and water balance, two pipelines of the oil discharge cavity and the oil discharge port can be relied on; and after long-time use, the original pressure balance can be kept; and when one pipeline malfunctions, the timely replacement or maintenance can be conveniently carried out.
Description
Technical field
The present invention relates to the hydraulics field, relate in particular to the two oil circuit reduction valve of a kind of rubber-moulding equipment.
Background technique
Rubber forming machine is a kind of high-accuracy high-efficiency rate glue embryo equipment, energy production high hardness, and the glue embryo of multiple abnormity, and glue embryo precision is high.For the hydraulic equipment of rubber forming machine to the steel pipe water pressure test, must guarantee oil-water balance state in whole hydrostatic test process, must guarantee that in this process Simultaneous Pressure changes, otherwise can occur steel pipe is damaged by pressure compressive strain and do not reach the purpose of pressure testing.General operation is that at oil pressure mouth dress proportional pressure-reducing valve or proportional pressure control valve, pressure transducer gathers the pressure data of water pump mouth at water pump mouth dress pressure transducer, pass to PLC, PLC sends instructions to Proportional valve again, produces an oil pressure that is slightly larger than hydraulic pressure, keeps this oil-water balance.In the process that keeps balance, only rely on out the single pipeline of oil pocket and drain tap, after use is permanent, can't guarantee original pressure balance, when a pipeline goes wrong, be unfavorable for changing timely or safeguarding.Therefore, for above aspect, need to make rational improvement.
Summary of the invention
The purpose of this invention is to provide a kind of without the pressure sensor, be conducive to realize the oil-water balance requirement, be convenient to going out the two oil circuit reduction valve of rubber-moulding equipment that oil pocket and drain tap safeguard, to solve many deficiencies of prior art.
Purpose of the present invention is come specific implementation by the following technical programs:
The two oil circuit reduction valve of a kind of rubber-moulding equipment comprise valve body and spool, and the valve inner center position arranges spool, are positioned at valve body that the center spool position is provided with an oil suction chamber and this spool end and are provided with one and go out oil pocket; The valve chamber that is arranged in the spool outside offers drain tap, this drain tap connect one section decompression shunting oil pipe and by this shunting oil pipe with go out oil pocket and be connected, described decompression is shunted on the oil pipe and is provided with the switch valve block.
Described drain tap is comprised of two sections oil circuits, be positioned at valve body wherein the inner chamber of an end arrange one control mouthful.
The beneficial effect of the two oil circuit reduction valve of rubber-moulding equipment of the present invention is: by shunting oil pipe and be equipped with external easy switch valve block in going out to set up between oil pocket and the drain tap one section decompression, in the process that keeps the oil-water balance experiment, can rely on out two pipelines of oil pocket and drain tap, after using for a long time, can guarantee original pressure balance, when a pipeline goes wrong, be convenient to change timely or safeguard.
