Abstract
Flexible disc Wedge gate valve.Mainly solve present Flexible disc Wedge gate valve, the axle center of flashboard for sluice valve is parallel with the axle center of valve body, and sealing effect is bad, easily occurs the problem of leaking.It is characterized in that: described flashboard (2) is up big and down small wedge-shaped structure, described valve seat (4) is provided with the sealing pair coordinated with described flashboard (2), and described valve seat (4) is obliquely installed and angle a formed by its axle center and described valve body (1) axle center is greater than 0 degree is less than 10 degree.The utility model provides Flexible disc Wedge gate valve, and its flashboard axle center and valve seat axle center angle a are less than 10 degree for being greater than 0 degree, and more agree with when valve closing, sealability is better.
Description
Technical field
The utility model belongs to gate valve field, particularly Flexible disc Wedge gate valve.
Background technique
Gate valve widely uses at oil, rock gas, chemical field, has been a kind of standardised generic product.In general, the slide-valve of gate valve to be a kind of closure member be parallel gate plate.Its closure member can be Single disc or therebetween with the double-flashboard of spreading mechanism.Flashboard is controlled by the pressure medium of effect with floating flashboard or floating valve seat to the impacting force of valve seat.If Double Disc Flat Gate Valves, then the spreading mechanism between two flashboards can supplement this impacting force.
Authorization Notice No. is " CN2329814 ", the Chinese patent that patent name is " Flexible disc Wedge gate valve " discloses a kind of Flexible disc Wedge gate valve, but the axle center of this flashboard for sluice valve is parallel with the axle center of valve body, sealing effect is bad, easily occurs leaking.
