Classification：Butterfly's valve
Trade names：
|
| |
| KD7T42/3P type (spring type is cut off promptly ) shuts in butterfly's valve quickly |
| Type of the products: KD7T42/3P |
|
|
The products are summed up:
And pump in the vapour heating type steam turbine system in the remaining energy electricity generation system of coal gas , this the west valve has got the extensive application day by day as the guarantee with safe system. It close rapidly , circulate obstruction smile , end can person who seal fine performance make their can replace system design electronic stop valve and non-return valve use originally. |
Use of the products:
Valve this spend on heat and power plant connect aircrew and coal gas remaining energy generating set in parallel mainly, use Israel as and protect the systematic security and have and cut off the valve promptly . |
Characteristic of the products:
1, close time and can be up to 0.5 seconds fast, it is safe and reliable to cut off promptly.
2, three partial metal is dense, seal the structure to open and close lightly and flexibly , seal zero to reveal.
3, the normal atmospheric temperature medium can be selected pair for use and leant towards soft-hearted sealed structure, the fabrication cost is low, it is reliable to seal.
4, the valve turn-off end is buffered, prevent the inertia of the valve from assaulting effectively.
5, can with spring realize imprison soon, liquid can with hold can device realize imprison soon, two kinds of forms play the same tune on different musical instruments, it is equally safe and reliable. |
