Abstract

The open a kind of rubber-moulding equipment controlled oil-feed air relief valve of the present invention, including valve body and spool, valve inner center position arranges spool, it is positioned at center spool position and is provided with an oil suction chamber and this spool lower surface is provided with one and goes out oil pocket, setting up one section of pressure piping below described oil suction chamber and this pressure piping is communicated to center spool chamber, this pressure piping is internally provided with movable plug.Present invention have the beneficial effect that by being provided above a pressure piping that can be communicated to center spool chamber in oil suction chamber, solve conventional apparatus rely solely on the single pipeline of oil suction chamber carry out startup operation and cannot guarantee oil circuit to center spool chamber oil-feed balance problem, it is simple to change timely or safeguard.

Description

A kind of rubber-moulding equipment controlled oil-feed air relief valve
Technical field
The present invention relates to technical field of hydraulic pressure, particularly relate to a kind of rubber-moulding equipment controlled oil-feed air relief valve.
Background technology
Rubber forming machine is a kind of high-accuracy high-efficiency rate glue embryo equipment, can produce high rigidity, the glue embryo of multiple abnormity, and glue embryo precision is high.For rubber forming machine to the hydraulic test of steel pipe water pressure test, it is necessary to ensure that oil-water balance state during the whole water pressure test, must assure that Simultaneous Pressure changes in the process, otherwise there will be and damage steel pipe by pressure compressive strain and do not reach the purpose of pressure testing.General operation is to fill pressure transducer at water pump mouth, and at oil pressure mouth dress proportional pressure-reducing valve or proportional pressure control valve, pressure transducer gathers the pressure data of water pump mouth, pass to PLC, PLC issues a command to proportioning valve again, produces an oil pressure being slightly larger than hydraulic pressure, maintains this oil-water balance.During keeping balance, rely solely on the single pipeline of oil suction chamber and carry out startup operation, it is impossible to guarantee that oil circuit balances to the oil-feed of center spool chamber, when a pipeline goes wrong, be unfavorable for changing timely or safeguarding.
Summary of the invention
It is an object of the invention to provide a kind of without pressure transducer, be advantageously implemented oil-water balance requirement, be easy to the rubber-moulding equipment controlled oil-feed air relief valve that oil suction chamber is controlled and safeguards, to solve many deficiencies of prior art.
The purpose of the present invention implements by the following technical programs:
A kind of rubber-moulding equipment controlled oil-feed air relief valve, including valve body and spool, valve inner center position arranges spool, it is positioned at center spool position and is provided with an oil suction chamber and this spool lower surface is provided with one and goes out oil pocket, setting up one section of pressure piping below described oil suction chamber and this pressure piping is communicated to center spool chamber, this pressure piping is internally provided with movable plug.
It is positioned in the valve chamber outside spool and offers drain tap, be positioned at body cavity and one control mouth is set.
Rubber-moulding equipment of the present invention controlled oil-feed air relief valve have the beneficial effect that by being provided above a pressure piping that can be communicated to center spool chamber in oil suction chamber, solve conventional apparatus rely solely on the single pipeline of oil suction chamber carry out startup operation and cannot guarantee oil circuit to center spool chamber oil-feed balance problem, it is simple to change timely or safeguard.
Accompanying drawing explanation
Below according to drawings and Examples, the present invention is described in further detail.
Fig. 1 is the structure chart of rubber-moulding equipment controlled oil-feed air relief valve described in the embodiment of the present invention.
In figure: 1, valve body;2, drain tap;3, oil pocket is gone out;4, oil suction chamber;5, mouth is controlled;6, spool;7, pressure piping;8, movable plug.
Detailed description of the invention
As shown in Figure 1, rubber-moulding equipment controlled oil-feed air relief valve described in the embodiment of the present invention, including valve body 1 and spool 6, at described valve body 1 inner hub location, spool 6 is set, the inner chamber being positioned at valve body 1 wherein one end arranges one-stage control mouth 5, is positioned at spool 6 centre and offers an oil suction chamber 4 and this spool 6 lower surface is provided with one and goes out oil pocket 3;It is positioned in valve body 1 chamber outside spool 6 and offers drain tap 2;It is important to note that, set up one section of pressure piping 7 below described oil suction chamber 4 and this pressure piping 7 is communicated to spool 6 central lumen, this pressure piping 7 is internally provided with movable plug 8, solve conventional apparatus rely solely on the single pipeline of oil-feed carry out startup operation and cannot guarantee oil circuit to central lumen oil-feed balance problem, it is simple to change timely or safeguard.
