Abstract
The invention discloses a decompression device capable of detecting oil drainage in the same direction for a rubber forming machine. The decompression device comprises a valve body and a valve core, wherein the valve core is arranged in the central position in the valve body, an oil inlet cavity is arranged at the central part of the valve core, and an oil outlet cavity is arranged in the valve body at the tail end of the valve core; and a valve body cavity positioned on the same side with the oil outlet cavity is provided with an oil drainage port in the same direction, and the oil drainage port comprises two sections of oil passages, namely that one section of upper end surface oil drainage branch and one section of lower end surface oil drainage branch are sequentially formed on the upper end surface of the valve core and the lower end surface of the valve core respectively. The decompression device disclosed by the invention has the beneficial effects that the decompression device is favorable for keeping the original pressure balance of an oil drainage part, and when one pipeline has a problem, the decompression device is convenient to replace or maintain in time; and simultaneously, as the oil drainage port is arranged on one side of the oil outlet cavity, during the experimental process of keeping oil-water balance, detection staff can simultaneously detect the pressure situation of the oil drainage port on one side of the oil outlet cavity and perform oil drainage on the oil drainage port, and the operation is convenient.
Description
Technical field
The present invention relates to the hydraulics field, relate in particular to a kind of decompressor that can detect in the same way draining for rubber forming machine.
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.When structure of relief pressure valve is set, usually all be that drain tap and the outer end that goes out oil pocket are opened in respectively on the valve body of spool both sides, detecting or during fuel-displaced process, detection then needs to be positioned at the valve body both sides and tests out respectively oil pocket and drain tap, fuel-displaced then the needs also arranges respectively twice to guarantee fuel-displaced process in both sides, thereby this structure exerts a certain influence to oil extraction efficient and pressure measurement speed; Simultaneously, when the pipeline of drawing from spool goes wrong, be unfavorable for changing timely or safeguarding.
Summary of the invention
The purpose of this invention is to provide and a kind ofly have a plurality of draining branch roads and go out the oil pocket branch road, be conducive to keep the oil-water balance requirement, be convenient to going out that oil pocket and drain tap detect in the same way and fuel-displaced being used for the decompressor that rubber forming machine can detect draining in the same way, with many deficiencies of solution prior art.
Purpose of the present invention is come specific implementation by the following technical programs:
A kind ofly can detect in the same way the decompressor of draining for rubber forming machine, comprise valve body and spool, the valve inner center position arranges spool, is positioned at the center spool position and is provided with an oil suction chamber, is provided with one in the valve body of spool end and goes out oil pocket; Be positioned at the valve chamber that goes out oil pocket the same side offer one in the same way drain tap and this drain tap formed by two sections oil circuits, namely spool upper-end surface, spool lower end surface are offered respectively successively one section upper-end surface draining branch road, one section lower end surface draining branch road and this two branch roads and all are communicated with drain tap in the same way.
Describedly go out oil pocket and be comprised of two sections oil circuits, namely spool intermediate cavity, spool lower end surface offer respectively successively that one section spool goes out the oil pocket branch road, the lower end surface goes out the oil pocket branch road; Be positioned at valve body wherein the inner chamber of an end arrange one control mouthful.
The beneficial effect that can detect in the same way the decompressor of draining for rubber forming machine of the present invention is: by two draining branch roads of being drawn by spool upper-end surface, spool lower end surface partly are set in drain tap, simultaneously, arrange two in fuel-displaced cavity segment and go out the oil pocket branch road by what drew valve core inside, spool lower end surface, be conducive to keep the original pressure balance of oil bleeding part, when a pipeline goes wrong, be convenient to change timely or safeguard; Simultaneously, by a drain tap being set simultaneously going out oil pocket one side, in the process that keeps the oil-water balance experiment, the inspector can detect the pressure condition of drain tap and drain tap is carried out oil extraction, convenient operation simultaneously going out oil pocket one side.
