Embodiment
The utility model is described further below in conjunction with the accompanying drawings：
A kind of low pressure device for detecting sealability, as shown in figure 1, including axle sleeve, sealing ring, valve body, valve element, spring, work
Door, tee pipe fitting, rubber tube and ball valve and microbraometer, the valve body（5）Interior one end is assembled with valve element（7）And valve（8）,
Valve element（7）And valve（8）Between be set with spring（6）, it is ensured that acting on bottom spool without external force（7）Valve can be blocked（8）,
Valve body（5）The other end is connected to and is detected the axle sleeve of measurement equipment connection, and the axle sleeve includes test side axle sleeve（1）With valve body end
Axle sleeve（2）, valve body end axle sleeve（2）With test side axle sleeve（1）Using sealing ring 1（3）Socket is tightly connected, test side axle sleeve
（1）Sealing ring 2 is used with tested measurement equipment（4）Socket is tightly connected, the valve（8）Pass through rubber tube 1（10）With three-way pipe
Part（9）Wherein one end connection, the tee pipe fitting（9）Other both ends pass through rubber tube 2 respectively（11）With rubber tube 3（12）
Connect microbraometer（14）And ball valve（13）.
Ball valve（13）It is connected with extraneous gas input equipment, when device works, opens ball valve（13）Thus port input gas
Body, control pressure is produced, by rubber tube and tee pipe fitting（9）, promote valve（8）Extrusion spring（6）It is deformed inward so that gas
Body passes through valve element（7）Into valve body（5）Cavity, then by valve body end axle sleeve（2）With test side axle sleeve（1）Inner chamber, flow to quilt
Detection device；Work as microbraometer（14）Reading when reaching the low pressure value of setting, cutting ball valve（13）, stop external inflation,
Observe microbraometer（14）Reading, according to numerical value change may determine that tested measurement equipment whether gas leakage, whether its sealing property
Meet the requirements.
