Abstract
The utility model discloses a craspedodrome journey butterfly valve, including valve rod, valve body, valve plate, valve shaft, disk seat, standard interface connection seat, standard interface connection seat and valve body rigid coupling have linked firmly the valve rod cover on the valve body, valve rod and valve rod cover swing joint, and swing joint has first connecting rod on the valve rod, and the one end swing joint of first connecting rod has the second connecting rod, and second connecting rod and valve plate swing joint have linked firmly end cover and axle sleeve on the valve body, be equipped with the valve plate locating pin on the valve shaft. The valve plate passes through link mechanism and realizes reciprocal linear motion, and the valve can realize very conveniently that the stroke is adjustable to the degree of opening of valve is directly perceived visible, the valve plate open that moment is little, head loss is little, can realize opening fast or closing of valve more conveniently, adopt the conical surface to seal up the disk seat firmly, seal up reliably durablely, the valve is furnished with the interface of standard, realizes delaying of valve and opens functions such as slowly closing and adjust, improves the application scope of valve.
Description
Technical field
The present invention relates to a kind of straight journey butterfly valve.
Background technique
Butterfly valve is that a kind of being arranged on pipeline can cut off medium and the valve regulating rate-of flow, because the simple volume of its structure is little, is a kind of valve be most widely used at present.Butterfly valve is primarily of valve rod, valve body, valve plate, valve shaft, valve seat composition.Existing butterfly valve, owing to affecting by performance and working condition, makes butterfly valve have many narrow limitation when selecting.
Summary of the invention
The object of the invention is to solve existing butterfly valve owing to affecting by performance and working condition, making butterfly valve have many circumscribed problems when selecting.
The technical solution used in the present invention is: a kind of straight journey butterfly valve, valve rod, valve body, valve plate, valve shaft, valve seat, valve plate is fixed on valve shaft, it also comprises standard interface connecting base, it is affixed that described standard interface connecting base and valve body pass through coupling bar, one end of described valve rod is stretched out outside valve through valve body and connecting base, described valve body is fixed with valve stem casing near standard interface connecting base place, valve rod is flexibly connected with valve stem casing, described valve rod is connected with first connecting rod, one end of described first connecting rod is connected with second connecting rod, described second connecting rod is flexibly connected with valve plate, described valve body is fixed with end cap and axle sleeve, one end of described valve shaft is flexibly connected with axle sleeve, the other end is provided with connecting rod locating stud and the other end of valve shaft and second connecting rod are connected, described valve shaft is provided with valve plate locating stud, valve plate realizes firmly sealing by the conical surface and valve base chamber.
As a further improvement on the present invention, the length of described first connecting rod is longer than second connecting rod, described valve body center line has certain distance to make valve body eccentric to valve rod centreline space, and the sealing surface place plane of valve plate and valve base chamber has certain distance to make valve plate eccentric to valve rod centreline space.
The invention has the beneficial effects as follows: valve plate realizes linear reciprocating motion by linkage mechanism, it is adjustable that valve can realize stroke easily, and the open degree of valve is intuitively visible; The unlatching moment of valve plate is little, loss of head is little, can realize opening or closing fast of valve more easily; When valve plate is opened, valve plate, away from valve body and valve seat, has that sufficient space is for convenience detach, maintenance, to change; Adopt the hard seal valve seat of the conical surface, seal reliability and durability; Valve is furnished with the interface of standard, can be connected with diaphragm, the drive unit such as pneumatic, electronic, thus realizes the functions such as the slow open and close of valve and adjustment, improves the Applicable scope of valve.
