Description
Technical field
The present invention relates to refrigeration technology fields, and in particular to the cubing of shut-off valve.
Background technology
The shut-off valve of refrigeration air-conditioner detects, and includes concentricity detection and sealing propertytest.Its concentricity mainly uses same
Heart degree cubing is detected, and high-precision cubing can detect most of bad, however, about leakproofness, portioned product is examined through water
Really it does not leak, still, micro- leakage can not be determine whether, lead to product rejection.
Invention content
Technical problem solved by the invention：Shut-off valve leakproofness detection tool structure is simplified, shut-off valve sealing propertytest is improved
Efficiency.
In order to solve the above technical problems, the present invention provides the following technical solutions：One linear sealing gas of shut-off valve examines cubing, including
Cubing ontology, flowmeter and low-pressure gas source, cubing body bottom portion open up detection mouth, gas passage, gas are equipped in cubing ontology
Channel is connected to the gas access in detection mouth and cubing ontology, and gas access is connect with flowmeter, low-pressure gas source；At least cubing
The bottom of ontology has elasticity, acts on the external force of cubing ontology downwards and can force the bottom of cubing ontology that flexible deformation occurs
And the detection mouth is made to be tightly connected with cut-off valve port.
According to the above technical scheme, shut-off valve is fastened, Flange Plane level where cut-off valve port is placed upward, opens low pressure gas
Source and flowmeter apply Flange Plane of the pressure where the deformation of Cowhells stick bottom surface is adjacent to cut-off valve port completely to Cowhells stick,
Observe flowmeter.Meter readings are 0, indicate that entire pipeline loop does not have air-flow to pass through, the valve seat and seal spool of shut-off valve
It is functional；Flowmeter is not 0, indicates that entire pipeline loop has air-flow to pass through, and valve seat has leakage with the spool place of fastening.
After do-over is done over again, after being detected by concentricity check tool, still there is part that can not ensure qualification, the actually part
Product is qualified.Cubing is examined using one linear sealing gas of shut-off valve of the present invention, it is ensured that product do over again after without micro- leakage situation,
Make above-mentioned concentricity check tool that can not ensure that qualified product is qualified.
Concentricity check tool can not be detected the small defect product in one line face of part, be used cooperatively of the present invention section
Only one linear sealing gas of valve examines cubing, can obtain whole detections with the product of batch with the portioned product, ensure that product is qualified, keep away
Exempt from batch scrap.

Specific implementation mode
One linear sealing gas of shut-off valve examines cubing, including cubing ontology 10, flowmeter and low-pressure gas source.
The cubing ontology 10 is Cowhells stick.
Such as Fig. 2,10 bottom of cubing ontology opens up detection mouth, and gas passage 11, gas passage connection are equipped in cubing ontology
Detection mouth is connected to the gas access on cubing ontology.At the gas access be equipped with tracheae connector 20, tracheae connector with
Extension tube attached connects, and extension tube attached is equipped with flowmeter, and extension tube attached is connect with low-pressure gas source.
The top of cubing ontology 10 is equipped with cylinder, and cylinder presses to the top of cubing ontology.
In conjunction with Fig. 1, Fig. 2, the lower section of cubing ontology 10 is equipped with flange frame 30, and flange frame opens up locating slot 32 and arc groove
31。
Above-mentioned flange frame 30, Cowhells stick, cylinder are connected by a rack, which is fixedly connected with flange frame, Cowhells stick
In rack, the cylinder is mounted in rack for activity cooperation.
In practical operation, shut-off valve is fastened, will be ended by the minimum torque operating valve core of standard requirement with reference to figure 1, Fig. 2
Valve 40 is located in the locating slot 32 of flange frame 30, and the Flange Plane where ending valve port is located in the arc groove 31 of flange frame,
The Flange Plane level is upward.
Cylinder action is in the top of Cowhells stick, and under the guiding of flange frame arc groove 31, Cowhells stick moves straight down, ox
The detection mouth docking cut-off valve port of muscle stick bottom.Low-pressure gas source and flowmeter are opened, in the presence of cylinder, Cowhells stick bottom hair
It gives birth to flexible deformation and the detection mouth is made to be tightly connected with cut-off valve port.
Flowmeter is observed, meter readings, which are the 0 entire pipeline loop of expression, does not have air-flow to pass through, valve seat and seal spool
It can be good；Flowmeter, which is not the 0 entire pipeline loop of expression, has air-flow to pass through, and valve seat has leakage with the spool place of fastening.
The above content is only the better embodiment of the present invention, for those of ordinary skill in the art, according to the present invention
Thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as to this hair
Bright limitation.
