embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Accompanying drawing 1,2,3 is the anti-vapour lock safety check of a kind of exhaust described in the utility model, comprises block 1, spherical rolling part 2, elbow 3, lower valve body 4, clack valve 5, upper valve body 6; Described upper valve body 6 is arranged on the top of lower valve body 4; Described upper valve body 6 is also communicated with and forms a fluid passage (not marking) with the inner hollow of lower valve body 4; Described clack valve 5 is arranged in fluid passage, fluid passage can be sealed; Described elbow 3 is arranged on lower valve body 4, the internal communication of the inside of described elbow 3 and lower valve body 4; The joint of described elbow 3 and lower valve body 4 is positioned at the below of clack valve 5; The outlet port of described elbow 3 is provided with block 1; On described block 1, be provided with through hole (not marking); In the inner passage of described elbow 3, be provided with spherical rolling part 2; Described spherical rolling part 2 can stop up the through hole on block 1.In the present embodiment, the inside of described lower valve body 4 is provided with step-like through hole; Described clack valve 5 hinges, at the step place of step-like through hole, can seal step-like through hole; Described upper valve body 6 screw threads are fixed on the larger diameter place of the step-like through hole of lower valve body 4; Described spherical rolling part 2 is arranged on by a chain (not shown) on the inwall of inner passage of elbow 3, unsceptered in the time not being stressed to prevent spherical rolling part 2, be that spherical rolling part 2 comes off from the inner passage of elbow 3, not in the inner passage of elbow 3; The inside top of described block 1 is provided with ball recess (not marking); Described through hole is arranged on the lowest part of ball recess; The angle of the vertical projection of the center line of the step-like through hole of the center line of the inner passage of described elbow 3 and lower valve body 4 is α, and 0 < α≤90 °, as shown in Figure 2; The center line of the inner passage of described elbow 3 is β with the angle of the horizontal vertical projection perpendicular to this center line, and 0 < β≤180 °, and as shown in Figure 3, elbow so arranges the discharge that can be conducive to the surplus air in spiral case.
