Detailed Description

For a better understanding of the technical solutions of the present invention, the following preferred embodiments of the present invention are described in conjunction with the specific examples, but it should be understood that the descriptions are only for the purpose of further illustrating the features and advantages of the present invention, and are not intended to limit the patent claims of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The utility model will be further described with reference to the accompanying drawings and preferred embodiments.

Example 1

Referring to fig. 1 and 2, the special-shaped ball valve according to the present embodiment includes a valve body 1, a valve seat 2, a ball body 3 and a valve rod 4, wherein a trigger handle 5 is disposed on the valve rod 4, and a limit hole 6 is disposed on the trigger handle 5; be equipped with spring hole 7 on the valve body 1, the wall cloth that spring hole 7 is close to the drill way has the internal thread, the drill way threaded connection of spring hole 7 has hollow nut 8, wears including gliding spacer pin 9 in the hollow nut 8, and the one end of spacer pin 9 stretches into spacing hole 6, the other end have the spacing portion 10 of establishing in spring hole 7, and the one end of spacing portion 10 supports hollow nut 8, the other end are equipped with the compression spring 11 of establishing in spring hole 7.

Furthermore, the limiting hole 6 is formed at one end of the trigger handle 5 far away from the valve rod 4.

In this embodiment, when the ball valve is in a closed state, the limit pin 9 in the pop-up state is inserted into the limit hole 6 to limit the rotation of the valve rod 4 carried by the trigger 5, and if the trigger 5 needs to be rotated, the limit pin 9 needs to be pressed to be separated from the limit hole 6, and then the trigger 5 can be rotated to adjust the valve rod 4 and the upper ball body 3.

The arrangement of the hollow nut 8 facilitates the opening of the spring hole 7, the installation of the limiting pin 9 and the compression spring 11, and the processing technology and the assembly flow are simplified.
