Abstract
The utility model discloses a working roll emulsion cooling control valve test and unkeep apparatus which comprises an air passage system and an electric control system. The air passage system comprises a air pipe connected with an air source. The air pipe is provided with a first air pipe branch connected with a control air chamber of an emulsion cooling control valve and a second air pipe branch connected with a simulated emulsion chamber of the emulsion cooling control valve. The air pipe is provided with an air pipe overall valve. The second air pipe branch is provided with a pressure-reducing valve. The electric control system comprises a power supply connected with an electromagnet arranged in the control air chamber and a control circuit used for controlling the connection and disconnection between a power supply and the electromagnet. Emulsion can be replaced through the utilization of compressed air which is the same with the emulsion in terms of pressure, so that test effects are realized and economical and environmental protection effects are also realized; whether working states of the emulsion cooling control valve in different frequencies are normal can also be detected, thereby guaranteeing the usage reliability of the emulsion cooling control valve after repairing; furthermore, fault reasons of the emulsion cooling valve can be relatively clearly determined; and basis is provided for fault repairing.

Background technology
At present, for the cooling operation valve of operation roll of mill emulsion, comparatively effectively do not monitor and repairing way, can only lean on test coil resistance and change the blindness failure judgement reasons such as diaphragm, in addition, also cannot reliably whether make judgement more accurately to the failure cause of operation valve and sensitivity.Therefore; after the cooling operation valve of working roll emulsion breaks down; can only under stopped status, repeatedly install and remove to judge; taken a large amount of production times; inefficiency, finally often can only solve problem by the operation valve more renewing, and the old operation valve of changing is because testing repairing; often can only scrap processing, cause serious waste.
Summary of the invention
In view of this, the purpose of this utility model is to provide the cooling operation valve test of a kind of working roll emulsion apparatus for examination and repair, this test apparatus for examination and repair can effectively judge the failure cause of the cooling operation valve of working roll emulsion, and provides theoretical foundation for the reparation of the cooling operation valve of emulsion.
For achieving the above object, the utility model provides following technical scheme:
The cooling operation valve test of a working roll emulsion apparatus for examination and repair, comprises air-channel system and electric-control system;
Described air-channel system comprises the tracheae being connected with source of the gas, described tracheae is provided with the tracheae branch road II that the tracheae branch road I that is connected with the control air chamber of the cooling operation valve of described emulsion is connected with simulated emulsion chamber with the cooling operation valve of described emulsion, described tracheae is provided with tracheae main valve, and described tracheae branch road II is provided with reduction valve;
Described electric-control system comprise be arranged on described control air chamber in the power supply that is connected of electromagnet and for controlling the control circuit of described power supply and described magnet switching.
Further, described control circuit comprises and the time relay of described electromagnet parallel connection and the time relay contact of connecting with described electromagnet.
Further, also comprise the vent valve being arranged on described control air chamber.
Further, also comprise for the test platform of the cooling operation valve of described emulsion is installed.
The beneficial effects of the utility model are:
The cooling operation valve test of working roll emulsion of the present utility model apparatus for examination and repair, by arrange air-channel system respectively with control air chamber and the simulated emulsion chamber of the cooling operation valve of emulsion, and on tracheae branch road II, reduction valve is set, utilize with the pressurized air of emulsion uniform pressure and replace emulsion, not only reached test effect but also economic environmental protection; By electrical control circuit is set, utilize control circuit to control the break-make frequency between power supply and electromagnet, whether normally can detect the duty of the cooling operation valve of emulsion under different frequency, thereby guarantee the dependability of the cooling operation valve of emulsion after reparation; In addition, utilize test apparatus for examination and repair of the present utility model, also can judge comparatively clearly the failure cause of the cooling valve of emulsion, for repairing fault, provide foundation.
