Abstract
The invention discloses a controlled oil-intake pressure reducing valve of rubber molding equipment. The controlled oil-intake pressure reducing valve of the rubber molding equipment comprises a valve body and a valve core; the valve core is arranged in 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 arrange at the lower end surface of the valve core; and a pressurization pipeline is added below the oil intake cavity, is communicated to the central chamber of the valve core, and is internally provided with a movable rubber plug. The controlled oil-intake pressure reducing valve of the rubber molding equipment provided by the invention has the beneficial effects that the pressurization pipeline capable of being communicated to the central chamber of the valve core is arranged above the oil intake cavity, so that the problem that the traditional device operates at the beginning only depending on the single pipeline of the oil intake cavity, and oil intake balance from an oil circuit to the central chamber of the valve core can not be guaranteed is solved, and timely replacement or maintenance is convenient.
Description
Technical field
The present invention relates to the hydraulics field, relate in particular to the controlled oil-feed 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 the single pipeline of oil suction chamber to carry out startup operation, can't guarantee oil circuit to the oil-feed balance of center spool chamber, when a pipeline 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 need not pressure transducer, be conducive to realize the oil-water balance requirement, be convenient to oil suction chamber and control and the controlled oil-feed reduction valve of the rubber-moulding equipment of safeguarding, to solve many deficiencies of prior art.
Purpose of the present invention is come specific implementation by the following technical programs:
The controlled oil-feed reduction valve of a kind of rubber-moulding equipment, comprise valve body and spool, the valve inner center position arranges spool, being positioned at the center spool position is provided with an oil suction chamber and this spool lower end surface and is provided with one and goes out oil pocket, described oil suction chamber below sets up one section pressure piping and this pressure piping is communicated to the center spool chamber, and this pressure piping inside is provided with movable plug.
The valve chamber that is arranged in the spool outside offers drain tap, is positioned at body cavity one control mouth is set.
The beneficial effect of the controlled oil-feed reduction valve of rubber-moulding equipment of the present invention is: by in the oil suction chamber top pressure piping that can be communicated to the center spool chamber being set, solved conventional apparatus and only relied on the single pipeline of oil suction chamber to carry out startup operation and can't guarantee oil circuit to the problem of the oil-feed balance of center spool chamber, be convenient to change timely or safeguard.
Description of drawings
The below is described in further detail the present invention with embodiment with reference to the accompanying drawings.
Fig. 1 is the structural drawing of the controlled oil-feed reduction valve of the described rubber-moulding equipment of the embodiment of the invention.
Among the figure: 1, valve body; 2, drain tap; 3, go out oil pocket; 4, oil suction chamber; 5, control mouth; 6, spool; 7, pressure piping; 8, movable plug.
Embodiment
As shown in Figure 1, the controlled oil-feed reduction valve of the described rubber-moulding equipment of the embodiment of the invention, 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, be positioned at spool 6 center portions and offer an oil suction chamber 4 and this spool 6 lower end surfaces and be provided with one and go out oil pocket 3; Valve body 1 chamber that is arranged in spool 6 outsides is offered drain tap 2; Need emphasis to be pointed out that, described oil suction chamber 4 belows set up one section pressure piping 7 and this pressure piping 7 is communicated to spool 6 central lumen, these pressure piping 7 inside are provided with movable plug 8, solved conventional apparatus and only relied on the single pipeline of oil-feed to carry out startup operation and can't guarantee oil circuit to the problem of the oil-feed balance of central lumen, be convenient to change timely or safeguard.
