Description

A kind of low pressure device for detecting sealability
Technical field
The utility model belongs to air-leakage test technical field, is related to low pressure air-leakage test, specifically a kind of low gas Means of press seals detection means.
Background technology
At present, existing device for detecting sealability(The low pressure device for detecting sealability of the 100kPa containing <)Structure all compare Compared with it is complicated, be inconvenient to safeguard, costly, volume is big, poor reliability, complex operation, be unfavorable for people to referring to low sealing The equipment that mark requires carries out sealing propertytest.
Utility model content
The purpose of this utility model is just to provide a kind of simple in construction, safe and practical, small volume, in light weight, cost is low, behaviour Make and safeguard all very easily low pressure device for detecting sealability.
Used technical scheme is the utility model to achieve these goals:
A kind of low pressure device for detecting sealability, including axle sleeve, sealing ring, valve body, valve element, spring, valve, three-way pipe Part, rubber tube and ball valve and microbraometer, one end is assembled with valve element and valve in the valve body, is set between valve element and valve There is spring, the valve body other end is connected to and be detected the axle sleeve of measurement equipment connection, and the valve passes through rubber tube and tee pipe fitting The connection of wherein one end, the other both ends of the tee pipe fitting pass through rubber tube and connect ball valve and microbraometer respectively.
The axle sleeve includes valve body end axle sleeve and test side axle sleeve, and valve body end axle sleeve is with test side axle sleeve using sealing Snare connects sealed connection, and test side axle sleeve is tightly connected with tested measurement equipment using sealing ring socket.
The beneficial effects of the utility model are that the device is also while whether detection equipment under test meets air-tightness requirement Possesses the features such as simple in construction, safe and practical, small volume, in light weight, cost is low, simple to operate and easy to maintenance.

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.
