Device may be provided for the Valve controlling functions such as regulation, urgent quick closedown.
For the application that some are special, such as large power plant main steam isolation valve, its valve mechanism belongs to
In gate valve pattern, bore is big, it is desirable to power output high, and require to be designed with security function: in urgent thing
Therefore under operating mode, driving means should provide valve function of quick closedown in 5 seconds.
Fluid pressure drive device is the functional requirement meeting above-mentioned operating mode quick closedown, needs to be equipped with a set of accumulation of energy
Device provides huge energy.Accumulating mechanism can use spring, it is also possible to uses compressed gas.Conventional
Product is knockdown design, and hydraulic cylinder is connected with energy storage equipment pipeline, complicated structure, huge
Volume and weight makes valve actuator be difficult to meet the security function under earthquake accident conditions.
Summary of the invention
It is an object of the invention to provide a kind of compact quick closing valve gas-liquid linked linear valve driving means knot
Structure, it is achieved the function of urgent quick closedown under accident conditions.
The present invention is achieved in that a kind of combined type nesting oil cylinder valve door drive, including hydraulic cylinder

Detailed description of the invention
As shown in Figures 1 and 2, a kind of combined type nesting oil cylinder valve door drive, including hydraulic pressure
Cylinder component 4, arranges piston rod 10 in the middle of hydraulic pressure cylinder assembly 4, arranges on hydraulic pressure cylinder assembly 4 sidewall
Electrically and instrument box 5 and motor hydraulic pump 6.
Described a kind of combined type nesting oil cylinder valve door drive, also includes being arranged on hydraulic pressure cylinder assembly 4
Hydraulic valve block assembly 2 on sidewall, little accumulator 3, wherein hydraulic valve block assembly 2 and little accumulator 3 are even
Connecing, hydraulic pressure cylinder assembly 4 includes three layers, interior China and foreign countries, i.e. hydraulic cylinder outer layer 7, hydraulic cylinder middle level 8, hydraulic cylinder
Internal layer 9, hydraulic cylinder middle level 8 connects with hydraulic cylinder internal layer 9, and piston rod 10 is arranged in cylinder pressure internal layer 9,
The piston head on piston rod 10 top and cylinder pressure internal layer 9 keep slidably compact siro spinning technology, in hydraulic cylinder middle level
Hydraulic oil 11 is set in 8, compressed gas 12, hydraulic oil 11 and compressed gas are set at cylinder pressure internal layer 9
12 are isolated by the piston head of piston rod 10, and hydraulic valve block assembly 2 connects with hydraulic cylinder middle level 8, and can
To control hydraulic oil 11 inlet.
Described hydraulic pressure cylinder assembly 4 is connected by bolt 1 and valve rack upper flange are fixing, piston rod 10
It is connected with outside valve rod.
When driving means is opened, the hydraulic oil of hydraulic pump inner layer hydraulic cylinder cavity of resorption can be driven to rush by motor
Pressure, when overcoming valve resistance and epicoele air pressure, can realize driving the unlatching of valve；The little storage arranged
Internal system pressure when energy device is used for maintaining valve wide open.Cavity of resorption oil circuit row is controlled on fast valve block when opening
When putting valve, owing to being acted on by middle level preliminary filling compressed gas, the hydraulic oil of hydraulic cylinder cavity of resorption discharges rapidly
To the fuel tank of outer layer, driving means can drive valve to perform quick closedown action in a short period of time, and
And valve can be kept under the influence of air pressure to be in closed position.
Such three-layer-liquid cylinder pressure designs, and simplifies structure to greatest extent, makes compact overall structure, and
Decrease the connection between parts, significantly reduce weight, improve the anti-seismic performance of entirety.Meanwhile,
Simple in construction, the probability of inefficacy reduces.
