Description
Technical field
The present invention relates to storage tank attachment (breather valve, fire arrester, deadweight safety valve etc.) detection fields, in particular to vehicular
Storage tank attachment (breather valve, fire arrester, deadweight safety valve etc.) detection device.
Background technique
Storage tank attachment (breather valve, fire arrester, deadweight safety valve etc.) is mounted on storage tank, guarantees the important of storage tank safety
Equipment.Relevant standard, regulatory requirements carry out periodic detection to storage tank attachment (breather valve, fire arrester, deadweight safety valve etc.), make
Storage tank attachment (breather valve, fire arrester, deadweight safety valve etc.) works normally, to ensure that storage tank is in a safe condition.The present invention
There are many technologies to limit to for detection device before, such as volume is big, gas source (can be blower, air pump) number is more, cannot survey
Amount bidirectional traffics index cannot quickly connect tested attachment, cannot simulate live attachment working condition pressure flow index simultaneously
Measurement, cannot automatically controlled changing flow direction and positive/negative pressure etc..
Summary of the invention
For skill existing for storage tank attachment (breather valve, fire arrester, deadweight safety valve etc.) detection device before the present invention
Art problem, the present invention provide a kind of vehicular storage tank attachment (breather valve, fire arrester, deadweight safety valve etc.) detection device, solve
These technical problems.
The present invention provides a kind of vehicular storage tank attachment (breather valve, fire arrester, deadweight safety valve etc.) detection devices, use
Same gas source (can be blower, air pump etc.) is come from the air-flow of detection pressure, flow, is realized by electric control reversing mechanism to quilt
Attachment positive/negative-pressure switching (switching of both forward and reverse directions flow) is examined, and the two-way airflow for flowing through tested attachment is surveyed by flowmeter
Amount measures relevant pressure temperature by pressure transmitter, temperature transmitter.
The function of electric control reversing mechanism of the present invention is as follows: when electric control reversing mechanism is switched to positive pressure (positive flow) and gas source
When (can be blower, air pump etc.) operates, outside air is entered by gas source (can be blower, air pump etc.) suction inlet, and by gas
(can be blower, air pump etc.) expiratory port blowout in source flows through the intermediary agencies such as measurement pipeline, reaches tested attachment.Make to be detected attached
Positive pressure is generated between part and present invention description vehicular storage tank attachment (breather valve, fire arrester, deadweight safety valve etc.) detection device
(being greater than outside air pressure) or the positive flow (exhalation flow) for flowing through tested attachment is generated simultaneously.Electric control reversing mechanism is switched to
When negative pressure (reverse flow) and gas source (can be blower, air pump etc.) operating, outside air is entered by tested attachment suction inlet, stream
Gas source (can be blower, air pump etc.) suction inlet is reached through part intermediary agency, and is exhaled by gas source (can be blower, air pump etc.)
Outlet blowout flows through pipeline discharge.Tested attachment and the present invention is set to describe vehicular storage tank attachment (breather valve, fire arrester, hydraulic
Safety valve etc.) negative pressure (being less than outside air pressure) is generated between detection device or generates the reverse flow for flowing through tested attachment simultaneously
(inhalation flow).
The present invention covers the installation site of two kinds of flowmeters, and two kinds of positions also result in the difference of the requirement to flowmeter.Two
Kind installation site is summarized as follows: position one, and flowmeter is mounted on gas source (can be blower, air pump etc.) expiratory port, this position is only
Needing the flowmeter of one direction flow measurement can meet the requirements.Position two, flowmeter is mounted on the pipeline of two-way airflow,
This position needs the flowmeter of twocouese flow measurement ability.
The positive minus flow switching mechanism (while being also positive/negative pressure switching mechanism), it is flat that the other end is connected with buffering detection
Platform, buffering detection platform include the cushion space that can accommodate certain volume gas, also include a connector, tested for installing
Attachment or intermediate structure (can be the intermediate match such as test panel device).
With fixed fast card connection mechanism in the buffering detection platform, since test need to be according to the tested attachment bore of difference
Specification switches different connecting test disks, and fixture is inserted in the fixed block on test panel, and sealing ring can guarantee sealing function when locking.
The test panel of this design fast and easy switching different pore size, and guarantee reliable sealing function.
The test panel, for connecting tested attachment, it (can be O-ring, rubber pad that test panel, which is fixed with soft sealing structure,
Deng), it seals when connecting tested attachment.The fixed position of soft sealing structure is according to the Flange Standard sealing position for being tested attachment
Set determination.This design distinguished makes soft sealing structure be fixed as one with test panel in other independent sealed structures, in connection attachment
When seal it is more reliable, more convenient, quick.To adapt to tested attachment bore, test panel has multiple specifications, can using fast mechanism for card
With quick-replaceable.
When tested attachment is connect with the test panel, to guarantee that leakproofness when detecting, this patent design have quickly
Hold-down mechanism, center connection ring are placed in tested attachment head, and earrings is connected on test panel or similar structures, and ratchet puller strap is worn
Center connection ring and earrings are crossed, when tensing ratchet puller strap, attachment is detected under a stretching force, is fixed on test panel.
Center connection ring, ratchet puller strap and earrings can be in multiple positions, and can have multiple.
