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 drainage port is formed in a valve body cavity positioned on the outer side of the valve core; the valve body cavity on the same side of the oil drainage port is provided with an oil outlet cavity in the same direction, and the oil outlet cavity in the same direction comprises two sections of oil passages, namely that one section of valve core oil outlet cavity branch and one section of lower end surface oil outlet cavity branch are sequentially formed in a middle cavity of the valve core and on the lower end surface of the valve core respectively; and one side of the oil outlet cavity is connected with a valve bottom pressure detection oil passage. 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, during the experimental process of keeping oil-water balance, detection staff can simultaneously detect the pressure situation of the oil outlet cavity on one side of the oil drainage port and perform oil drainage on the oil outlet cavity.
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 oil pocket pressure 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, the pressure test mouth for fuel-displaced part is not enough.
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 oil pocket pressure 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 oil pocket pressure 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, and the valve chamber that is positioned at the spool outside offers drain tap; Be positioned at valve chamber with drain tap the same side and offer to go out in the same way oil pocket and this and go out in the same way oil pocket and formed by two sections oil circuits, namely be positioned at spool intermediate cavity, spool lower end surface offer respectively successively one section spool go out oil pocket branch road, lower end surface go out oil pocket branch road and this two branch roads all with go out in the same way oil pocket and be communicated with; Describedly go out oil pocket one side connection valve bottom pressure and detect oil circuit.
Described drain tap is comprised of two sections oil circuits, namely is positioned at spool upper-end surface, spool lower end surface and offers respectively successively one section upper-end surface draining branch road, one section lower end surface draining branch road; Be positioned at valve body wherein the inner chamber of an end one control mouthful is set, the valve bottom pressure detects in the oil circuit a movable plug is set.
The beneficial effect that can detect in the same way the decompressor of oil pocket pressure 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, detect oil circuit by set out simultaneously oil pocket and valve bottom pressure in drain tap one side, in the process that keeps the oil-water balance experiment, the inspector can detect out the pressure condition of oil pocket simultaneously and carry out oil extraction, convenient operation to going out oil pocket in drain tap one side.
