Description
Technical field
The utility model relates to a kind of triple valve, particularly a kind of novel three-way plug valve.
Background technology
Plug valve is the rotary valve of closure member or plunger shape, makes the passway on valve plug communicate or separate with the passway on valve body by 90-degree rotation, realizes a kind of valve of opening or closing. It is cylindrical or conical that the shape of the valve plug of plug valve can become. In cylindrical valve plug, passage is generally orthogonal; And in cone-shaped valve plug, passage in echelon. These shapes become lightly a kind of structure of being particularly related to of plug valve, but have also produced certain loss simultaneously. Plug valve is suitable for being suitable for as cutting off and connect medium and shunting most, but according to applicable character and the abrasion-resistance of sealing surface, sometimes also can be used for throttling. It because motion between plug valve sealing surface is with wiping action, and in the time of standard-sized sheet, can prevent completely and the contacting of flow media, therefore also can be used for the medium with suspended particulate conventionally. When another key property of plug valve, it is easy to adapt to multi-channel structure, so that a valve can obtain two, three, even four different runners. Can simplify like this some connection fittings that need in design, minimizing valve consumption and the equipment of pipe-line system. The service life of existing threeway plug valve is low, and poor sealing performance need to be changed frequently, very trouble.
