Embodiment Construction

[0012] see figure 1 The lockable ball valve shown includes a valve body 1, the two ends of the valve body have joints 2, and the two ends of a ball 4 are arranged in the valve body through a sealing ring 3. The valve rod 5 passes through the valve rod cavity on the valve body and forms a rotating pair with the valve body, and the lower end of the valve rod is connected with the ball through a groove. The upper end 51 of the valve stem is lower than the periphery 11 of the upper end of the valve stem chamber. The lower end of the key 10 can extend into the valve stem chamber and cooperate with the upper end of the valve stem to drive the valve stem to rotate. The key booster rod 11 passes through the top of the key 1 .

[0013] The lower end of the valve stem has a thrust journal 52, and the thrust journal is located in the thrust step at the bottom of the valve stem chamber.

[0014] see Figure 4 , A limit washer 7 for limiting the rotation angle of the valve stem is arra...

Abstract

The technology provides a lockable ball valve, which only can be opened and closed by using a special key and can effectively prevent the occurrence of the stealing phenomenon. The lockable ball valve comprises a valve body, wherein the two ends of the valve body are provided with joints; the two ends of a ball are arranged in the valve body by sealing rings; a valve rod penetrates through a valve rod cavity on the valve body and forms a revolute pair with the valve body; the lower end of the valve rod is connected with the ball; and the upper end of the valve rod is lower than the periphery of the upper end of the valve rod cavity. The ball valve also comprises a key which can extend into the valve rod cavity, is matched with the upper end of the valve rod and is used for driving the valve rod to rotate.

Description

technical field [0001] The technology relates to a ball valve, specifically, a lockable ball valve that can prevent being opened or closed at will. Background technique [0002] The existing ball valve includes a valve body, the two ends of the valve body have joints, the two ends of the ball are arranged in the valve body through the sealing ring, the valve stem passes through the valve stem cavity on the valve body and forms a rotating pair with the valve body, the valve The lower end of the stem is connected with the ball; the upper end of the valve stem is connected with the handle on the upper part of the valve body. The valve stem is driven by the turning handle to realize the rotation of the ball and drive the opening and closing of the valve. But this kind of ball valve, anyone can turn the handle at will to switch the valve, and there is no anti-theft function. Contents of the invention [0003] The purpose of this technology is to provide a lockable ball valve ...
