Abstract
The utility model discloses a verification connecting device of a liquid level transmitter. The verification connecting device of the liquid level transmitter is composed of an inserting barrel on the front portion of the device, a middle cover in the middle of the device and a tail tube on the rear portion of the device. The inserting barrel and the middle cover are connected by a bolt through a flange and a blind flange, and the middle cover and the tail tube are connected through a threaded connection head and a threaded connection groove. A connecting tube inside the tail tube is communicated with an inner cavity of a barrel body through a through tube inside the middle cover. In the using process, a sensing probe of the liquid level transmitter is inserted into the inner cavity of the barrel body from an inserting opening of the inserting barrel, a conical inserting head of the tail tube is inserted into one end of a plastic hose to be connected, the other end of the plastic hose is connected with a standard instrument, the air supply pressure of the standard instrument can fully, effectively and accurately act on the sensing probe of the liquid level transmitter in the inner cavity of the barrel body through the through tube of the middle cover and the connecting tube of the tail tube, the special-shaped sensing probe can also be connected with the standard instrument, periodic verification and calibration of the liquid level transmitter can be guaranteed, and the precision and accuracy of the on-line liquid level transmitter are ensured.
Description
One, technical field
The utility model belongs to testing tool technical field, is specifically related to a kind of transmitter verification coupling arrangement.
Two, background technology
In metering measuring instrument operational process, must carry out periodic calibration and calibration according to national regulation, with the accuracy that guarantees that metering detects.And the throw-in type fluid level transmitter using at present, because its sensing probe profile is special, causes reference instrument to be connected with it, affect the carrying out of fluid level transmitter periodic calibration and calibration, cannot guarantee on-line metering accuracy of instrument and accuracy.
Three, summary of the invention
The purpose of this utility model is to provide a kind of transmitter verification coupling arrangement, adopt this device can make the probe of the special fluid level transmitter sensing of profile also can be connected with reference instrument, guarantee the carrying out of fluid level transmitter periodic calibration and calibration, guarantee on-line metering accuracy of instrument and accuracy.
For achieving the above object, the technical solution adopted in the utility model is: this coupling arrangement is made up of the middle cover at anterior insertion tube, middle part and the tail pipe at rear portion, and insertion tube is made up of the interior empty cylindrical shell at forward sockets, middle part and the flange at rear portion; Middle cover is made up of threaded connector and the inner siphunculus at anterior blind flange, rear portion; Tail pipe is made up of the groove that is threaded of front portion, cone-shaped plug and the inner connecting pipe at rear portion; Insertion tube is connected by bolt by flange, blind flange with middle cover, and middle cover is threaded connection head with tail pipe and the groove that is threaded is connected; The connecting pipe of tail pipe inside communicates through the siphunculus of middle cover inside and the inner chamber of cylindrical shell.
When use, the sensing probe of fluid level transmitter is inserted and is placed in cylinder lumen from the socket of insertion tube, the cone-shaped plug of tail pipe is inserted to plastic flexible pipe one end to be connected, the plastic flexible pipe other end is connected with reference instrument, the defeated bleed pressure of reference instrument is by the siphunculus of middle cover and the connecting pipe of tail pipe, just can be all effective, act on exactly on the fluid level transmitter sensing probe in cylinder lumen, the special sensing probe of profile also can be connected with reference instrument, guarantee the carrying out of fluid level transmitter periodic calibration and calibration, precision and the accuracy of online fluid level transmitter are guaranteed.The utility model is simple in structure, reasonable in design, replenishes the blank of this type of coupling arrangement, is worth applying widely.
Four, accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Five, embodiment
As shown in the figure, the utility model is made up of the middle cover 2 at anterior insertion tube 1, middle part and the tail pipe 3 at rear portion.Insertion tube 1 is made up of the interior empty cylindrical shell 17 at forward sockets 4, middle part and the flange 8 at rear portion; Middle cover 2 is made up of threaded connector 10 and the inner siphunculus 11 at anterior blind flange 9, rear portion; Tail pipe 3 is made up of cone-shaped plug 18 and the inner connecting pipe 14 at be threaded groove 12, the rear portion of front portion.Insertion tube 1 is connected by bolt 7 by flange 8, blind flange 9 with middle cover 2, middle cover 2 and tail pipe 3 be threaded connection 10 and the groove 12 that is threaded be connected.The connecting pipe 14 of tail pipe 3 inside communicates with the inner chamber of cylindrical shell 17 through the siphunculus 11 of middle cover 2 inside.Be provided with the holding screw 5 that can screw in cylindrical shell 17 inner chambers in the outside of cylindrical shell 17, it is fastening that its effect is that transmitter 6 sensing probes 13 to inserting carry out, and prevents its loosening gas leakage.Between flange 8 and blind flange 9, be provided with O-ring seal 19, the interior loop-shaped of O-ring seal 19 is identical with the outer shape of sensing probe 13, can increase like this sealing, has guaranteed verification effect.In figure, 15 is plastic flexible pipe; 16 is reference instrument.
