Description
Technical field the utility model relates to gas Leak Detection field, particularly a kind of coupling arrangement of leak locator.
The gas circuit coupling part of background technology leak locator of the prior art and measured piece comprises the gas circuit assembly, machine shell panel, seal valve, test port, test port joint or seal valve vertically are installed on the outside of a certain panel of leak locator, mounting means makes like this: it is long that the mechanical part of leak locator test port joint or seal valve stretches out the machine shell panel of instrument, make troubles to packed and transported, and very easily damage test port joint or seal valve during carrying, even can influence the sealing of leak locator inner air path assembly because of test port joint or seal valve are subjected to the external force touching, cause the leak locator can't operate as normal.
In the leak locator use, need the timer-controlled self-inspection instrument.During instrument self checking, for test port the leak locator of seal valve is not installed, the flexible pipe that needs dismounting earlier to be connected with measured piece down refills the plug screw that instrument is worn, and seals to be fastened on the test port of leak locator, carries out the self check demarcation of instrument sealing property.After the self check of instrument sealing is qualified, back out fastening plug screw again, load onto the flexible pipe that is connected with measured piece.The test port of instrument often because the repeatedly fastening and dismounting of plug screw causes leak locator self to leak, also brings very big inconvenience to the operator simultaneously.
Instrument test mouth joint is interior accessibke porosity, mostly be because of mounting means at present perpendicular to machine shell panel, making test interface is horizontal level, and the through hole of level is introduced dust, water droplet, foreign material etc. easily in filling, enter in the deflation course sealing gas circuit assembly, causes instrument damage.
The summary of the invention the purpose of this utility model is for fear of the existing deficiency of above-mentioned prior art products, and a kind of compact conformation is provided, technology is reliable, failure rate is low, easy to use, the packing of product simple, the coupling arrangement of the leak locator of carrying safety.
The purpose that the utility model proposed can realize by technical scheme:
A kind of coupling arrangement of leak locator comprises that leak locator is connected with the gas circuit of measured piece, promptly comprises the test interface gas circuit connects in the leak locator test gas circuit assembly connector, test gas circuit assembly and measured piece;
Test interface comprises interconnective high-pressure hose, ball valve and test port joint, and ball valve connects test gas circuit assembly by high-pressure hose;
To measured piece inflation, balance, pressure test, leak locator detects the leakage rate of measured piece to leak locator by test gas circuit assembly connector, test gas circuit assembly, high-pressure hose, ball valve and test port joint;
Particularly: the test interface gas circuit connects and comprises ball valve, ball valve mounting bracket, ball valve handle and high-pressure hose in the leak locator, ball valve is installed on the machine shell panel of back closely by the ball valve mounting bracket, and be screwed, the ball valve that gas circuit connects in the test interface is parallel with machine shell panel;
The upper end of ball valve is flexible coupling by the test gas circuit assembly of high-pressure hose with test gas circuit assembly connector and rectangle, the lower end of ball valve is flexible coupling by test port joint, high-pressure hose and measured piece, the lower end that is ball valve is connected with measured piece, installation direction is straight down, ball valve and be equipped with the protective cover covering protection above the high-pressure hose;
Ball valve is as the on-off switch that connects test gas circuit assembly and measured piece, and whether the decision leak locator is communicated with the measured piece gas circuit, and the conversion of self check and test is convenient, when needing self check, turns ball valve handle, and the gas circuit of leak locator and measured piece is turn-offed, and is used for self check; Twist return of serve valve handle, open ball valve, leak locator is communicated with the measured piece gas circuit, leak locator is detected.
As a further improvement of existing technologies, the lower end of ball valve is connected with measured piece, and installation direction is straight down, and installation direction or skew are less than 360 degree.Ball valve is installed on the machine shell panel of back closely by the ball valve mounting bracket, and is screwed, and ball valve or directly be close to screw is fixed on the machine shell panel.
The beneficial effects of the utility model are:
With respect to prior art, ball valve in the test interface of leak locator connection measured piece is close on " crouching " leak locator machine shell panel, promptly the ball valve clinching is fixed on the machine shell panel with the ball valve mounting bracket, ball valve one end is flexible coupling by the test port joint and the test gas circuit assembly of high-pressure hose and leak locator, the ball valve other end is flexible coupling by high-pressure hose and measured piece, solved the mounting means of traditional " semi-girder " formula perpendicular to machine shell panel, reduce the valve member that is installed on the machine shell panel or the extension elongation of other test port joint effectively, made leak locator be convenient to the packing carrying.
Designing on the high-pressure hose of an end of connection test gas circuit assembly in the ball valve has the protective cover covering protection, and the installation direction of ball valve lower end is straight down, prevents that the presumable dust of measured piece inner chamber, foreign material, water droplet from entering ball valve, avoids damaging leak locator.
Because the test gas circuit assembly of the coupling arrangement inside of leak locator is connected with ball valve one end by high-pressure hose, measured piece is connected with the ball valve other end by high-pressure hose again, make the whole connected system of coupling arrangement of leak locator all be flexible coupling, thereby the external vibration distortion can not influence the sealing property of instrument internal.
Ball valve is as the on-off switch that connects test gas circuit assembly and measured piece, opens then that leak locator is communicated with the gas circuit of measured piece, and leak locator is detected state; Close then that the gas circuit of leak locator and measured piece disconnects, leak locator is the self check state, and the conversion of self check and test mode is very convenient.
During the leak locator self check, the connection high-pressure hose that connects measured piece need not to take off, not only handled easily but also can reduce by foreign matter and enter the probability that causes the leak locator fault.The ball valve of test interface was not closed when leak locator was not worked, and avoided foreign matter to enter the damage leak locator.
The utility model is compared with prior art products, compact conformation, technology is reliable, failure rate is low, easy to use, the packing of product is simple, volume is little, carrying security performance height and test performance is reliable.
Description of drawings
Fig. 1 is the coupling arrangement structural representation of leak locator;
The cross section structure figure that Fig. 2 installs for the test interface ball valve.
Embodiment is further explained the utility model below in conjunction with embodiment:
In Fig. 1, Fig. 2,1 is measured piece, and 2 is high-pressure hose, and 3 is ball valve handle, 4 is ball valve, and 5 is test interface, and 6 is protective cover, and 7 is the test port joint, 8 is the ball valve mounting bracket, and 9 is machine shell panel, and 10 are test gas circuit assembly, and 11 are test gas circuit assembly connector.
