Preferably, the assembling seat in adjacent valve door sealing testing agency is in being wholely set.

Pass through technique scheme, in order to be able to prevent adjacent valve door sealing testing agency from relative displacement occurring, assembling seat in adjacent valve door sealing testing agency have employed the mode being wholely set, i.e. valve sealing detection machine structure is installed in same assembling seat simultaneously, even if in operating process, operator surprisingly touch one of them valve sealing detection machine structure, and adjacent valve sealing detection machine structure also will not occur relative displacement.

Preferably, adjacent guide table is in being wholely set.

By technique scheme, valve and the locating slot generation locator card cooperation used time in guide table, valve lateral wall can be with locating slot cell wall generation effect of impact, and adjacent guide table is in being wholely set, and makes the anti seismic efficiency of whole one guide table be strengthened.

3rd purpose of the present utility model is to provide a kind of detecting system that can intuitively observe valve internal sealing property.

3rd technical purpose of the present utility model has the technical scheme that a kind of detecting system, including workbench, described workbench is provided with above-mentioned detection device, for controlling flexible power part and whether being passed through the switching device of gas with external pipe simultaneously, for detecting the pressure tester of external trachea air pressure inside size, described switching device, pressure tester all with the setting of valve sealing detection machine structure one_to_one corresponding.

Pass through technique scheme, operator can realize whether being controlled the ventilation of each flexible power part and external trachea by switching device, and when in test process, the air pressure of valve internal can directly be detected by pressure tester, when air pressure reaches expectation index, valve seal performance is qualified;When air pressure is not up to expectation index, valve seal performance is defective.

Preferably, described pressure tester is Pressure gauge.

By technique scheme, Pressure gauge is cheap, easy for installation and can accurately detect the atmospheric pressure value size of valve internal, gives operator with vision-based detection result intuitively.
