Referring to fig. 1 to 5, three embodiments of the present invention are provided:

the first embodiment is as follows: the utility model provides a prevent from gathering sealed ball valve firmly with protective structure, includes first casing 1 and second casing 4, and first casing 1 is installed through fastening screw 5 and second casing 4 intercommunication, and movable mounting has case body 7 in the second casing 4. One side of first casing 1, keeping away from second casing 4, is that annular array has seted up

installation screw

6, and 1 inboard embedding of first casing

installs sealing washer

8, and 8 one sides of the inboard sealing washer of first casing 1 contact but not fixed connection with 7 outer walls of case body. The inner side of the second shell 4 is embedded with a sealing ring 8, and one side of the sealing ring 8 at the inner side of the second shell 4 is in contact with but not fixedly connected with the outer wall of the valve core body 7.

Example two: the utility model provides a prevent from gathering sealed ball valve firmly with protective structure, includes first casing 1 and second casing 4, and the bearing body 9 is installed in 4 top trompils of second casing and embedding above the

case body

7, and 9 top fixed mounting of bearing body have clamp body 10, and clamp body 10 inboard clamps in the recess of dwang 11 outer wall. A rotating rod 11 is embedded in the bearing body 9. The inside perforating hole that is equipped with of case body 7, the mounting hole has been seted up at case body 7 top, and the mounting hole cross section at case body 7 top adopts hexagon structural design, and 11 bottom cartridges of dwang are in the mounting hole at case body 7 top.

Example three: the utility model provides a prevent from gathering sealed ball valve firmly with protective structure, includes first casing 1, second casing 4 and

dwang

11, and 11 bottom cross sections of dwang adopt hexagon structural design, and 11 top fixed mounting of dwang have spanner body 3. The upper surfaces of the second shells 4 at the two ends of the front end of the rotating rod 11 are respectively provided with holes and movably inserted with limiting bolts 2. Through setting up spacing bolt 2 to even spacing bolt 2 respectively movable mounting is downthehole in second casing 4 upper surface both sides opening, thereby carry on spacingly to spanner body 3 through two spacing bolts 2, thereby avoid spanner body 3 to appear rotating the condition, thereby the restriction is installed and is rotated in case body 7 in second casing 4 appears, thereby play stagnant water or open the effect in water course, reached and avoided the valve automatic effect of opening or closed.
