Abstract
The utility model discloses a ball valve with a bidirectional limiting device. The ball valve with the bidirectional limiting device comprises a valve body and a valve rod, wherein the terminal end of the valve rod is provided with a limiting cross bar; the valve body is provided with a first limiting bump and a second limiting bump; the second limiting bump extends along the axial direction of the valve body; and the first limiting bump extends along the radial direction of the valve body. The ball valve with the bidirectional limiting device, disclosed by the utility model, has the advantages of being simple and convenient and further providing convenience for users to operate as the first limiting bump and the second limiting bump used for respectively indicating a completely close state and a completely open state of the ball valve are arranged on the valve body.
Description
Technical field
The utility model relates to a kind of valve, or rather, is a kind of ball valve with bidirectionally limited device.
Background technique
Ball valve; Be defined as among the standard GB/T21465-2008 " valve term ": open-shut device (spheroid) is driven by valve rod; And the valve that rotates around the axis of valve rod; Be mainly used in the medium that blocks or connect in the pipeline, also can be used for the adjusting and the control of fluid, be specially adapted to media such as fibre-bearing, small solid particle.Generally only be provided with a restriction protrusion on the valve body of existing ball valve, be used to indicate rest position, on the perforation position, then do not have any indicating device.When working environment was dark, the user was difficult to make that ball valve is on the position that connects fully.
Summary of the invention
The utility model mainly is to solve the existing in prior technology technical problem, thereby a kind of ball valve with bidirectionally limited device is provided.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of ball valve with bidirectionally limited device comprises valve body and valve rod, and the end of described valve rod is provided with a spacing horizontal stripe, and described valve body is provided with one first restriction protrusion and one second restriction protrusion.
As the preferred embodiment of the utility model, described second restriction protrusion axially extends along described valve body, described first restriction protrusion radially extending along described valve body.
The ball valve with bidirectionally limited device of the utility model is provided with first restriction protrusion and second restriction protrusion on valve body; Be used for indicating respectively ball valve fully by with connect this two different state fully; Simple and convenient, further convenience is provided for user's operation.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiments of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the perspective view with the ball valve of bidirectionally limited device of the utility model;
Fig. 2 is the details enlarged diagram with the a-quadrant of the ball valve of bidirectionally limited device among Fig. 1;
Wherein,
1, with the ball valve of bidirectionally limited device; 2, valve body; 21, first restriction protrusion; 22, second restriction protrusion; 3, valve rod; 31, spacing horizontal stripe.
Embodiment
Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection domain of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.
To shown in Figure 2, a kind of ball valve 1 with bidirectionally limited device comprises valve body 2 and valve rod 3 like Fig. 1, and the end of this valve rod 3 is provided with a spacing horizontal stripe 31, and this valve body 2 is provided with one first restriction protrusion 21 and one second restriction protrusion 22.
This second restriction protrusion 22 axially extends along this valve body 2, this first restriction protrusion 21 radially extending along this valve body 2.
The above is merely the embodiment of the utility model, but the protection domain of the utility model is not limited thereto, and any variation or replacement of expecting without creative work all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with the protection domain that claims were limited.
