Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a sealed sample valve, handle 1 including

valve body

10 and 10 upsides of valve body, 1 fixedly connected with pivot 13 of handle, 1 downside of handle closes soon and is connected with sealed lid 2, pivot 13 rotates and is connected with case 3, valve pocket 12 has been seted up to valve body 10 inboard, import 11 has been seted up in valve pocket 12 left side, export 4 has been seted up to valve pocket 12 downside,

valve pocket

12 and 3 sliding connection of case, 10 downside of valve body is provided with

sample jar

5, 5 bottoms of sample jar are provided with threaded rod 7, the inside cover of sample jar 5 is equipped with baffle 6, scale 14 has been seted up in the 5 outsides of sample jar, twist grip 1 drives pivot 13 and rotates and reciprocates, it reciprocates to drive case 3, the shape characteristic of.

Specifically, as shown in fig. 1, threaded rod 7 runs through sample jar 5 and runs through the first stopper 8 of the equal fixed connection in a both sides, two first stoppers 8 respectively with 5 trompil departments both sides butts of sample jar, first stopper 8 has ensured that threaded rod 7 can not rotate from top to bottom when rotating.

Specifically, as shown in fig. 1, the sealing cover 2 is fixedly connected with the valve body 10, so that the air tightness of the valve is ensured.

Specifically, as shown in fig. 1, the inner wall of the sampling tank 5 is fixedly connected with a second limiting block 9, and the second limiting block 9 is connected with the notch of the partition plate 6 in a sliding manner, so that the partition plate 6 is ensured not to rotate.

Specifically, as shown in fig. 1, the threaded rod 7 is connected with the partition plate 6 in a threaded manner, and the threaded rod 7 is rotated to adjust the partition plate 6 to move up and down so as to control the sampling amount.
