Abstract
The utility model relates to a parabola-shaped valve deck which comprises a valve deck body (1). The top portion of the valve deck body and a valve deck body lower end (2) are transited through arc connection, and a parabola (3) and a parabola (4) are formed on a cross section of the valve deck body. Due to the fact that parabolas are formed on the cross section of the valve deck body, casting rate of finished products of the valve deck is improved, cost is reduced, appearance of a valve is attractive, meanwhile the valve deck is unlikely to be abraded due to bumping, and service life of the valve deck is prolonged.
Description
Technical field
The utility model relates to a kind of valve valve gap, particularly a kind of parabola shaped valve gap.
Background technique
Valve gap is one of major part of valve, plays a part to valve rod location and sealed valve body, and common valve gap profile is circular or corner angle are arranged that be difficult for casting, and have the valve gap of corner angle to wear and tear because of collision easily, the working life of valve gap is shorter.
The model utility content
The purpose of this utility model solves valve gap exactly and is difficult for casting and easy wear problems.
The technical solution adopted in the utility model is: a kind of parabola shaped valve gap comprises the valve gap body.Valve gap body top is connected transition with valve gap body lower end by arc, forms parabola in the cross section of valve gap body.
The utility model beneficial effect is: because the utility model forms parabola in the cross section of valve gap body, improved the qualified casting of valve gap, reduced cost, made valve elegant in appearance.
Description of drawings
Fig. 1 is the plan view of the utility model valve valve gap.
Fig. 2 is that the utility model valve valve gap A---A is to sectional view.
Embodiment
As shown in Figure 1, 2, a kind of parabola shaped valve gap comprises valve gap body 1.Valve gap body top and valve gap body lower end 2 are connected transition by arc, form parabola 3,4 at the valve gap body section.Form parabola at valve in the cross section of valve gap body, improved the qualified casting of valve gap, reduced cost, make valve elegant in appearance, be difficult for simultaneously wearing and tearing because of collision, prolonged the working life of valve gap.
Claims (1)
1. a parabola shaped valve gap comprises valve gap body (1), it is characterized in that described valve gap body (1) top is connected transition with valve gap body lower end (2) by arc, forms parabola (3,4) in the cross section of valve gap body.
