The utility model proposes a kind of fixing apparatus for filter 100, are used for Fixed-Filter 300.
Fig. 1 to Fig. 3 is please referred to, filter 300 includes the first lid 310 and the second lid 320, and the first lid 310 deviates from
The side of second lid 320 is equipped with first sleeve 311, and fixing apparatus for filter 100 includes:
Bottom plate 1, bottom plate 1 are equipped with holding tank 12 and the inlet channel 11 that is connected to holding tank 12;
Clamping piece 2, is set to bottom plate 1, and clamping piece 2 includes clamp assemblies 21, the notch of the corresponding holding tank 12 of clamp assemblies 21
Equipped with butt junction 212;
First sleeve 311 is contained in holding tank 12 and is connected to inlet channel 11, the first lid 310 and the second lid
320 abut and are enclosed accommodating chamber 330, and butt junction 212 is abutted with the second lid 320 backwards to the side of the first lid 310, gas
Stream enters accommodating chamber 330 from inlet channel 11 and first sleeve 311, to detect at the first lid 310 and 320 abutting of the second lid
Leakproofness.
It is input in filter 300 it should be noted that air tightness detection equipment will control the accurate compressed air of pressure,
Then source of inflation gas is automatically shut down, solenoid valve accurately controls the air balance of stipulated time, then has turned off the electromagnetism of balanced action
Valve, air-leakage test is by the accurate little differential pressure sensor that is connected by test specimen with the same gas circuit of standard component, at the appointed time
Standard component and the differential pressure value by test specimen are measured, then obtains the pressure generated by the practical leakage of test specimen by temperature-compensating
Drop, to judge whether test specimen leaks.In the technical scheme, air tightness detection equipment and inlet channel 11 deviate from first sleeve
311 side connection, so that air be inputted in accommodating chamber 330.
In technical solutions of the utility model, first sleeve 311 is limited in holding tank 12, and the second lid 320 with abut
First 212 abut, so that filter 300 is limited between bottom plate 1 and clamping piece 2, air-flow enters accommodating chamber from inlet channel 11
In 330, to use the sealing of air tightness detection equipment detection filter 300 first lid 310 and 320 junction of the second lid
Property, the fixed device of the filter 300 is not only simple in structure, and can reduce space occupied;And it convenient for operation, and then can be improved
Detection efficiency.
Specifically, pressure is larger when leak detection, it is necessary to tested article pressure can be just sealed, can with oil cylinder or
Cylinder is sealed, but cylinder or oil cylinder volume are larger, damage in order to prevent to operator, need operator's
Both hands exit after operating area, can just press control button starting oil cylinder or cylinder.And in the present embodiment, operator
Filter 300 is buttressed on the other hand, in addition a hand operates clamping piece 2, so that it may realize the second lid 320 away from the first lid 310 1
Then the sealing of side can detect the leakproofness of filter 300 by gas leak detection device, operation is not only simple quickly, and
And it is very safe.
In the present embodiment, the length of depth with first sleeve 311 of holding tank 12 is suitable, so that first sleeve 311 is held
When being contained in holding tank 12, the lateral wall of the first lid 310 is abutted with the upper surface of bottom plate 1, prevents filter 300 from inclining
Tiltedly.
