Overview:

The parallel double sluice gate valve is suitable for the medium for water, sewage pipe for CCTV equipment on the road, not allowed to adjust flow and emptying of use. Widely used in petroleum, chemical, pharmaceutical, electric power industries. In the nominal pressure or less l. 0 mpa of media such as steam, water, oil piping for opening and closing. Our factory can produce parallel type double gate valve and parallel type single parallel type double ram disc gate, rising stem gate valves, rising stem parallel single disc gate valves.

working principle：

Parallel double gate valve is a kind of ceramic gate valve. Therefore, its structure and working principle and gate, the opening and closing body (disc) by stem drive the valve seat sealing surface for lifting movement, can be connected or channels to cutting fluid. When the valve is partially open, creates turbulence on the back of the disc, easy cause erosion and vibration of the gate, also easy to damage the valve seat sealing surface, repair difficulties, usually applies to don't need to often open/close, and keep the gate full open or full close condition.

Parallel double gate valve working principle: by means of the cylinder or the handwheel provide outside power, move up and down the stem drive disc realize opening and closing of the valve, the valve opening and closing process relies on set spring pre-tightening force between double ram is close contact between disc and seat, make the seal.
