Abstract
The invention provides a fixed form of a hydraulic servomotor in an electro-hydraulic control system. The fixed form solves the problems of quick ageing and invalidation of a guide sleeve and a pipe joint sealing element of the hydraulic servomotor because the hydraulic servomotor close to an oil cylinder works under a high-temperature environment for a long term. The fixed form is characterized in that: a hydraulic servomotor bracket is fixed on a table top at one end of an inverse T-shaped transition plate, the hydraulic servomotor is fixed on the hydraulic servomotor bracket in an inverse mode, and one end of the transition plate is fixed on a bent plate; and a lever is provided by using an upright post of the T-shaped transition plate as a pivot (C), one end of the lever is hinged (A) with a hydraulic servomotor piston rod, the other end of the lever is hinged (B) with a driving high-pressure adjusting valve lever mechanism, and two sides of the pivot (C) are provided with equal arms. The fixed form has the advantage that the hydraulic servomotor is integrally moved outside to keep away from the oil cylinder serving as a heat source.
Description
Technical field
The present invention relates to the fixed form of oil engine in the electrohydraulic steam turbine controlling system.
Background technique
The fixed form of electrohydraulic steam turbine controlling system oil engine is, oil engine is fixed on by transition plate on the bent plate that is close to the steam turbine high-pressure cylinder cylinder body, and the oil engine piston rod drives the high-pressure regulation porthole by leverage.Because oil engine is taken root on bent plate, bent plate is pressed close to the high-pressure cylinder cylinder body, thereby oil engine directly is subjected to the conduction heat of the radiation heat and the bent plate of high-pressure cylinder cylinder body, the temperature that causes oil engine piston rod place is up to about 180 ℃～200 ℃, long-term work is under hot environment, cause the quick aging of oil engine guide sleeve and pipe seal part to be lost efficacy, lose seal action and leakage of oil.Influence safety, the reliable operation of unit.
Summary of the invention
For solving this radiation heat and conduction heat problem, the objective of the invention is to, a kind of fixed form with oil engine in the electrohydraulic steam turbine controlling system that prevents radiation heat and the hot heat-blocking action of conduction is provided.
The object of the present invention is achieved like this: it comprises the bent plate of transition plate, oil engine and steam turbine high-pressure cylinder cylinder body, it is characterized in that: said transition plate is inverted T-shaped, the oil engine support is fixed on the table top of transition plate one end, oil engine is fixed on the oil engine support with upside down, be that the high-order layout of oil engine, piston rod are downward, an end of transition plate is fixed on the bent plate; Column at T shape transition plate is established lever as fulcrum (C), lever one end and oil engine piston rod hinged (A), and the lever the other end and driving high-pressure regulation porthole leverage hinged (B), fulcrum (C) both sides are equiarm.Working procedure is, the oil engine piston rod is to bottom offset, and the other end of lever drives high-pressure regulation porthole leverage constant amplitude to top offset, drives to regulate porthole and open, and finishes an adjustment process.Vice versa.The present invention moves oil engine integral body outward by leverage, away from this thermal source of oil cylinder.
Compared with prior art, the invention has the beneficial effects as follows: guaranteeing under the constant condition of oil engine structure, function, performance (comprising moving direction, stroke, quick closing valve time), oil engine is high-order to be arranged, whole outer moving, stow away from heat, oil engine have been avoided radiation heat and conduction heat, thoroughly eliminated long-term work under hot environment, make oil engine piston rod and pipe seal part inefficacy leakage of oil, and improved the arrangement space of oil engine, the easy access management.
Description of drawings
Further specify the present invention below in conjunction with accompanying drawing.
Accompanying drawing is a structural representation of the present invention.
