Abstract
The utility model discloses an electric ball valve, which comprises a valve body, a valve cover arranged on the valve body, and a valve seat. A ball valve is arranged inside the valve seat. The upper part of the ball valve is provided with a valve stem connected with an actuator. As an improvement, the edge of the matched part of the valve cover and the valve seat is provided with an annular groove. A sealing ring is arranged inside the groove. According to the utility model, the annular groove is arranged between the valve cover and the valve seat mutually matched with each other and the sealing ring is arranged inside the annular groove. Thus, the design margin in the valve body is reduced and the design accuracy is lowered. Meanwhile, the ball valve is corrected to be in a proper position under the elasticity action of the sealing ring. During rotation, since the ball valve is connected with the actuator through the valve stem, the switching force exerted on the valve is greatly reduced. The wear intensity of the actuator is minimized.
Description
Technical field
The utility model relates to a kind of electric ball valve.
Background technique
Electric ball valve is main through the rotation of motorized motions ball valve in pipeline, cuts off or distribute and change the flow direction of medium, and it only need just can close tight with revolving the operation that turn 90 degrees and very little moment of rotation.Optimum is made switch, cut-off valve uses, and can ball valve design become to make it have the usefulness of throttling and control flow rate.These require precision-fit sealing between the valve seat, valve gap, valve body of electric ball valve, have improved the fabricating cost of valve seat, valve gap, valve body.
Summary of the invention
The hard sealing cost height that the utility model in use exists for solving existing technology, problems such as valve inner spare accuracy of manufacturing height provide a kind of good seal performance, the electric ball valve that cost is low.
The technological scheme that the utility model solves existing issue is an electric ball valve; Comprise valve body, be arranged at valve gap and valve seat on the valve body; Be provided with ball valve in the valve seat, ball valve top is provided with valve rod and connects final controlling element, as improvement; Described valve gap and valve seat cooperation place avris are provided with annular recess, are provided with seal ring in the described groove.
As further improvement, described seal ring is the O RunddichtringO.
As further improvement, described two valve gaps are arranged at the valve seat both sides respectively, and valve gap and valve seat cooperation place avris are provided with annular recess, are provided with seal ring in the described groove.
As further improvement, described side valve lid is fixed on the valve body, and the opposite side valve gap is bolted on the valve body.
The utility model compared with prior art, its beneficial effect is through between valve gap that matches and valve seat, annular groove being set, seal ring being set in the annular groove; Both can reduce the valve inner design margin dwindles; Reduce design accuracy, the ball valve of the elasticity of seal ring correction simultaneously is in the appropriate location, when ball valve connects actuator turns through valve rod; Switch dynamics to valve significantly reduces, and reduces the wear intensity to final controlling element.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Referring to Fig. 1, this case study on implementation comprises valve body 1, is arranged at valve gap 2 and valve seat 3 on the valve body 1, is provided with ball valve in the valve seat 2; Ball valve top is provided with valve rod and connects final controlling element; Valve gap 2 is provided with annular recess 21 with valve seat 3 cooperation place avris, is provided with seal ring 22 in the groove 21, and seal ring 22 is the O RunddichtringO.
In this case study on implementation, two valve gaps 2 are arranged at valve seat 3 both sides respectively, and valve gap 2 is provided with annular recess 21 with valve seat 3 cooperation place avris, and seal ring is positioned at groove 21.Wherein side valve lid 2 is fixed on the valve body 1, and opposite side valve gap 2 is bolted on the valve body 1.
