Abstract
The utility model discloses a reliever with a plurality of oil outlet cavity branches and used for a water pressure test. The reliever with the plurality of oil outlet cavity branches and used for the water pressure test comprises a valve body and a valve core. The valve core is arranged at the central position inside the valve body. An oil inlet cavity is formed at the central portion of the valve core. An oil outlet cavity is formed in the valve body which is located at the tail end of the valve core. The oil outlet cavity comprises two sections of oil ways. Namely, a valve core oil outlet cavity branch is arranged on the middle cavity of the valve core, and a lower end face oil outlet cavity branch is arranged at the lower end of the valve core. The two branches are communicated with the oil outlet cavity. The reliever with the plurality of oil outlet cavity branches and used for the water pressure test has the advantages that due to the fact that the oil drainage ports are provided with two oil drainage port branches introduced from the lower end face of the valve core and the inner potion of the valve core, flow direction of the oil way on the side of the oil outlet cavity is guaranteed totally according to the direction of the water pressure experimental control opening in the process of an experiment of keeping the balance of oil and water. Original pressure balance of the oil outlet cavity can be kept and timely replacement or maintenance is convenient to achieve when a problem occurs in a pipeline.
Description
Technical field
The utility model relates to the hydraulics field, relate in particular to a kind of for hydraulic pressure test with a plurality of decompressors that go out the oil pocket branch road.
Background technique
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, go out oil pocket 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 provide a kind of have a plurality ofly go out the oil pocket branch road, be conducive to keep the oil-water balance requirement, be convenient to go out that oil pocket safeguards be used for hydraulic pressure test with a plurality of decompressors that go out the oil pocket branch road, 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 for hydraulic pressure test with a plurality of decompressors that go out the oil pocket branch road, comprise valve body and spool, the valve inner center position arranges spool, be positioned at the center spool position and be provided with an oil suction chamber, the valve body that is positioned at the spool end is provided with one and goes out oil pocket, this goes out oil pocket and is comprised of two sections oil circuits, namely be positioned at spool intermediate cavity, spool lower end surface and offer respectively successively that one section spool goes out the oil pocket branch road, one section lower end surface goes out the oil pocket branch road, these two sections branch roads all with go out oil pocket and be communicated with.
The valve chamber that is arranged in the spool outside offers drain tap, be positioned at valve body wherein the inner chamber of an end one control mouthful is set.
Described in the utility modelly for hydraulic pressure test with a plurality of beneficial effects that go out the decompressor of oil pocket branch road be: go out the oil pocket branch road by partly arrange two in drain tap by what spool lower end surface and valve core inside were drawn respectively, in the process that keeps the oil-water balance experiment, the oil circuit that can guarantee this side of oil pocket flows to fully according to the direction of hydrostatic test control mouthful and carries out, be conducive to keep the original pressure balance of fuel-displaced cavity segment, 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.
Fig. 1 be the utility model embodiment described for hydraulic pressure test with a plurality of structural drawing that go out the decompressor of oil pocket branch road.
Among the figure: 1, valve body; 2, drain tap; 3, go out oil pocket; 4, oil suction chamber; 5, control mouth; 6, spool; 7, spool goes out the oil pocket branch road; 8, the lower end surface goes out the oil pocket branch road.
Embodiment
As shown in Figure 1, the utility model embodiment described for hydraulic pressure test with a plurality of decompressors that go out the oil pocket branch road, comprise valve body 1 and spool 6, described valve body 1 inside center position arranges spool 6, be positioned at valve body 1 wherein the inner chamber of an end one section control mouthfuls 5 is set, being positioned at valve body 1 that spool 6 center portions offer an oil suction chamber 4 and this spool 6 ends is provided with one and goes out oil pocket 3, this goes out oil pocket 3 and is comprised of two sections oil circuits, namely be positioned at spool 6 intermediate cavity, spool 6 lower end surfaces are offered respectively successively one section spool and are gone out oil pocket branch road 7, one section lower end surface goes out oil pocket branch road 8, in the process that keeps the oil-water balance experiment, can guarantee that oil circuit flows to the direction of controlling according to hydrostatic test fully and carries out, be conducive to keep the original pressure balance of oil bleeding part; Simultaneously, valve body 1 chamber that is arranged in spool 6 outsides is offered drain tap 2.
