Abstract
The utility model discloses an integrated air brake control device, which comprises a pneumatic automatic control electromagnetic valve, a pneumatic hand-operated control valve and a hand-operated automatic selection control valve, and is characterized by further comprising an integrated valve seat, wherein an air guide way is arranged in the integrated valve seat, an air guide hole is arranged on the surface of the integrated valve seat, the pneumatic automatic control electromagnetic valve, the pneumatic hand-operated control valve and the hand-operated automatic selection control valve are connected with the integrated valve seat, and the air guide hole on the surface of the integrated valve seat, the air guide way in the integrated valve seat, and air guide holes on the pneumatic automatic control electromagnetic valve, the pneumatic hand-operated control valve and the pneumatic automatic selection control valve can form a hydraulic turbine set air brake control loop. Compared with an existing air brake device, the integrated air brake control device has the advantages of simple structure, convenient maintenance and installation, high reliability, safety and free leakage as adopting a standard plate type connecting pneumatic element and highly integrating the air brake loop in the valve seat, which can be widely applied in waterpower and other fields.
Description
Technical field
The utility model belongs to air control unit, is specifically related to a kind of integrated form air brake controls that water power plant hydraulic generator unit is shut down that are used for.
Background technique
The existing Pneumatic braking device that is used for water power plant hydraulic generator unit shutdown is reached by resolution element to be made up of the huge pipe joint of quantity, steel pipe, hand stop valve and two or more solenoid valve mostly.This Pneumatic braking device complex structure, number of elements and of a great variety, assembling processing time and effort consuming.And cause leakage point to increase owing to being connected with pipe joint, be easy to generate leakage phenomenon after use a period of time, even cause braking maneuver not in place, can not provide safe and reliable protection for the normal operation of hydraulic generator unit because of leakage reduces air pressure with steel pipe.
Summary of the invention
The purpose of this utility model is to provide a kind of integrated form air brake controls, to address the above problem.
The technical solution of the utility model is: the integrated form air brake controls, it comprises pneumatic automatic control electromagnetic valve, Pneumatic and manual control valve, the manual control valve of selecting automatically, it is characterized in that it also comprises integrated valve seat, offer airtube in the integrated valve seat, the integrated valve seating face is provided with gas port, and pneumatic automatic control electromagnetic valve, Pneumatic and manual control valve and manually automatic selection control valve are connected with integrated valve seat; Constitute water wheels unit gas brake servo circuit between airtube in the gas port of integrated valve seating face, the integrated valve seat and pneumatic automatic control electromagnetic valve, Pneumatic and manual control valve and the manually automatic gas port of selecting on the control valve.
Compare with existing Pneumatic braking device, the remarkable advantage of the utility model patent is: the board-like connection pneumatic element of employing standard, and gas brake circuit height is integrated among the valve seat, and simple in structure, convenient for installation and maintenance, the reliability height, safety does not have and leaks.The utility model patent can be extensive use of in other fields such as hydroelectric powers.
