Detailed Description

Embodiments of the present invention are further described with reference to fig. 1 to 2.

A ball valve comprises a valve body 1, wherein a valve seat 2, a ball body 4 and a handle 3 for controlling the rotation of the ball body 4 are arranged in the valve body 1, a connecting channel 40 is arranged in the ball body 4, a medium channel 10 is arranged in the valve seat 2, the medium channel 10 is in a connected state or a disconnected state through the rotation of the ball body 4, a notch 41 is arranged on one side of the ball body 4, the top end of the notch 41 corresponds to the position of the medium channel 10 on the valve seat 2, a sealing block 5 is closed on the notch 41, the sealing block 5 is provided with an arc-shaped surface, the arc-shaped surface is consistent with the radian of the outer surface of the ball body 4 to form a sealing arc surface sealed with the medium channel 10, an inserting block 50 is connected onto the sealing block, an inserting groove 42 for inserting the inserting block 50 is arranged on the ball body 4, a limiting ring 420 is arranged at the notch of the inserting groove, the bottom of the valve body 1 is provided with a water outlet 11, one end of the insertion block 50 extends to the water outlet 11 and is provided with a sealing plug 53, when the sealing plug 53 is pulled to move to the outside of the body, the second positioning ring 52 on the insertion block 50 slides out of the slot 42, a water drainage channel 54 is formed between the sealing block 5 and the ball 4, and a gap is formed between the insertion block 50 and the water outlet 11. The water outlet 11 of the valve body 1 is in threaded fit with a cover body 6, and the cover body 6 is abutted against the sealing plug 53. Two annular sealing rings 530 are arranged on the sealing plug 53, and the sealing rings are made of rubber materials.

When the valve is closed, the ball 4 is rotated by the handle 3, so that the medium channel 10 on the ball 4 is staggered with the connecting channel 40 on the ball 4, and the medium channel 10 is in a disconnected state. At this time, the medium is likely to be trapped between the sealing surface of the ball 4 and the sealing surface of the valve seat 2. When the medium needs to be discharged, the cover body 6 at the water outlet 11 is firstly disassembled by screwing, then the sealing plug 53 is pulled, so that the sealing plug 53 slides out of the water outlet 11, the sealing plug 53 drives the insert block 50 to move downwards in the moving process, so that the second positioning ring 52 on the insert block 50 moves out of the slot 42, the water supply and drainage channel 54 is formed between the sealing block 5 and the ball 4, the position of the drainage channel 54 corresponds to that of the medium channel 10, the retained medium can flow to the water outlet 11 along the drainage channel 54, and finally the retained medium is placed outside the valve body 1. The diameter of the insert 50 is smaller than the diameter of the sealing plug 53, so that a space is formed between the insert 50 and the drain opening 11 for the medium to drain.

The insert 50 is divided into an upper end having a first retaining ring 51 and a second retaining ring 52, and a lower end having a sealing plug 53. The upper end portion is inserted into the lower end portion for rotational engagement such that the insert 50 is configured to not interfere with the movement of the ball 4 when the ball 4 is rotated by the handle 3.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection.
