Abstract
The utility model discloses a parataxis-type spilled oil bypass reduced pressure device for testing the water pressure. The parataxis-type spilled oil bypass reduced pressure device for testing the water pressure comprises a valve body and a spool. The spool is arranged in the center position inside the valve body, and an oil inlet cavity is arranged in a center part of the spool. An oil drainage port is arranged inside a cavity of the valve body, wherein the cavity of the valve body is located in the outer side of the spool. A section upper end surface spilled oil branch road, a section spool spilled oil branch road and a section lower end surface spilled oil branch road are respectively located on the upper end surface of the spool, the middle cavity of the spool and the lower end surface of the spool in sequence. The parataxis-type spilled oil bypass reduced pressure device for testing the water pressure has the advantages that three spilled oil branch roads respectively brought from the upper end surface of the spool, the spool inside and the lower end surface of the spool, during experiments keeping oil and water balanced, the oil road flow direction can be ensured completely in accordance with the direction of the water pressure control opening. The parataxis-type spilled oil bypass reduced pressure device for testing the water pressure is beneficial for the keeping the original pressure balance of the spilled oil part. When one pipeline goes wrong, the parataxis-type spilled oil bypass reduced pressure device for testing the water pressure is convenient to change or maintain in time.
Description
Technical field
The utility model relates to the hydraulics field, relates in particular to a kind of abreast-type for hydraulic pressure test and rushes down oily by-pass reducing device.
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, drain tap is when carrying out work, only possesses the single pipeline that picks out from spool, after using for a long time, can't guarantee the original pressure balance of the fuel-displaced chamber portion of valve inner and oil extraction efficient, when the pipeline of drawing when this spool goes wrong, be unfavorable for changing timely or safeguarding.
The model utility content
The purpose of this utility model provides a kind ofly to be had a plurality of draining branch roads, be conducive to keep the oil-water balance requirement, be convenient to rush down oily by-pass reducing device to going out the abreast-type that is used for hydraulic pressure test that oil pocket and drain tap safeguard, to solve many deficiencies of prior art.
The purpose of this utility model is come specific implementation by the following technical programs:
A kind of abreast-type for hydraulic pressure test is rushed down oily by-pass reducing device, comprises valve body and spool, and the valve inner center position arranges spool, is positioned at the center spool position and is provided with an oil suction chamber; The valve chamber that is arranged in the spool outside offers drain tap, is positioned at spool upper-end surface, spool intermediate cavity, spool lower end surface and offers respectively successively one section upper-end surface draining branch road, one section spool draining branch road, one section lower end surface draining branch road.
Be provided with one in the valve body of described spool end and go out oil pocket, be positioned at valve body wherein the inner chamber of an end arrange one control mouthful.
The beneficial effect that abreast-type for hydraulic pressure test described in the utility model is rushed down oily by-pass reducing device is: by three draining branch roads of being drawn respectively by spool upper-end surface, valve core inside, spool lower end surface partly are set in drain tap, in the process that keeps the oil-water balance experiment, can guarantee that oil circuit flows to complete direction according to hydrostatic test control mouth and carries out, be conducive to keep the original pressure balance of oil bleeding part, when a pipeline goes wrong, be convenient to change timely or safeguard.
Description of drawings
The below is described in further detail the utility model with embodiment with reference to the accompanying drawings.
