Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
As shown in Figure 1, 2, a kind of sampling probe in coal dust workshop, including cylinder 1 and the sampling mouth for being located at the one end of cylinder 1
2, cylinder 1 is divided by the flange 3 of a transversal setting is provided with the first passage 4, flange 3 four for front and rear two parts, the center of flange 3
Week is provided with some second passages 5, and the latter half of cylinder 1 is provided with air chamber 6, and the top and bottom of air chamber 6 are equipped with valve
601.A piston 7 is provided with air chamber 6, piston 7 can do piston movement up and down in air chamber 6, and the top of piston 7 is connected with one
Connecting rod 8, the other end of connecting rod 8 are connected to micro hydraulic cylinder 9.Under original state, piston 7 be in air chamber 6 top or
Lowermost end.
Check valve 10 is designed with the first passage 4 and the second passage 5 of flange 3.As shown in figure 3, check valve 10 wraps
Rotating shaft 101 is included, and the baffle plate 102 and magnet 103 being connected in rotating shaft 101, baffle plate 102 adsorb in not extraneous additional force
On the magnet 103, so to allow the first half of gas from cylinders 1 to flow to later half for 10, the check valve of the first passage 4
