Description

The ship cylinder fast valve
Technical field
The utility model relates to a kind of valve member that under the state of emergency, uses, and the particularly a kind of HS of being applied to type ship is used the cylinder fast valve, can be used for industry pipe-line systems such as boats and ships, marine drilling platform, oil, chemical industry.
Background technique
At present; Shipbuilding of China industry is in the three big indexs that show the shipbuilding industry competitive ability---aspect the amount of accepting an order, non-delivery size of order, the construction amount all above Korea S; Leap to the first in the world; And be accompanied by under the powerful financial assistance of Chinese Government, the ocean shipping company of China has sent large-scale order to the domestic shipbuilding industry of China once more, and Shipbuilding of China has already been consolidated world-class status.Fast valve is the necessary equipment that uses when using oil transport pipeline emergency cut-off such as boats and ships, oil, chemical industry; Every the above boats and ships of ton need be used about 30 covers; The fast valve peculiar to vessel that uses at present is mostly with reference to GB5744 standard design and manufacturing; Performance can not satisfy the technical requirements of contemporary shipbuilding industry, and major defect is as follows:
1, traditional fast valve is after long-range cutting out, and valve member can not automatically reset and preload.The tradition fast valve must reset and preload by artificial on-site manual before realizing long-range once more quick closedown, but because the cabin space is narrow and small, pipe fitting is installed factors such as intensive complicacy, makes fast valve reset and preload work realization inconvenience.
2, traditional fast valve reset and preload process more loaded down with trivial details.The tradition fast valve must on-site manual resets and the whole process of preload comprises following step: at first; Change hands wheel clockwise, be lower than mainshaft nut, treat gas emptying in cylinder and the connecting pipeline then up to the cylinder latch; After the cylinder latch resets, rotating counterclockwise handwheel until the highest line journey.The latch of cylinder is easy to owing to the improper of operator damages in this process.
3, traditional fast valve pressure rating is low excessively.The fast valve peculiar to vessel that uses at present is mostly with reference to GB5744 standard design and manufacturing; The Maximum operating pressure of fast valve has only 0.25Mpa; Part valve member manufacturer makes the fast valve Maximum operating pressure be increased to 1.0Mpa through increasing methods such as valve body wall thickness, increase spring; But this just improved the fast valve importer to pressure, and the fast valve outlet pressure has only 0.1-0.3Mpa all the time under the valve member closed condition, in order to guarantee that the situation that fluid flows backwards does not take place under the state of emergency that valve member is closed; Shipyard generally connects a stop valve in the outlet of fast valve, has so just improved the user cost of traditional fast valve.
4, traditional fast valve part unbalance stress is impaired easily.The tradition fast valve operation cylinder latch vertical with the motion of main shaft direction; Under the valve member opening state; Become because the long term power of spring force makes latch be easy in the motion of main shaft direction non-resilient type to take place, thereby make fast valve realize closing or closing fully under the state of emergency again.
