Abstract

A kind of meter-clamping apparatus, belongs to flow apparatus Calibration Technology field.Comprise cylinder, the reciprocation pipe of suit and the expansion bend cylinder body of tail pipe composition, described cylinder is arranged on reciprocation pipe by its two end cap, and connect with tail pipe, cylinder is connected with support to support, the rear and front end of described cylinder covers and has annular groove, be tightly connected respectively by O RunddichtringO between annular groove two ends and reciprocation pipe, between described annular groove and reciprocation pipe, be respectively equipped with guidance tape.The utility model designs and produces simply, easy to operate, good concentricity, good airproof performance, and flexible reciprocation pipe can not be caused to sink, and convenient processing, can not damage 0 type circle by pressure, can not cause the gas leak phenomenon that leaks, and makes Zheng health check-up Ding Installed and puts perfection.

Description

A kind of meter-clamping apparatus
Technical field
The invention belongs to flow apparatus Calibration Technology field, particularly relate to a kind of meter-clamping apparatus.For large-scale flow apparatus calibrating flow instrument, tong-test ammeter equipment.
Background technology
Existing pneumatic expansion joint, draw-tube sealing is by 0 type circle sealing, and the weight of draw-tube is also by 0 type circle holder.Due to the draw-tube weight of large-scale pneumatic expansion bend, during tong-test ammeter, 0 type circle is pressed inclined modification, causes the gas leak phenomenon that leaks, and causes and cannot examine and determine flow instrument.Because 0 type circle modification causes draw-tube to sink, draw-tube and cylinder body are joined together and cause grinding phenomenon, cannot stretch.
Summary of the invention
For the technical matters of above-mentioned existence, the invention provides a kind of meter-clamping apparatus.Its good concentricity, good airproof performance, can not cause flexible reciprocation pipe sink and produce the gas leak phenomenon that leaks
The object of the invention is to be achieved through the following technical solutions:
The present invention includes cylinder, the reciprocation pipe of suit and the expansion bend cylinder body of tail pipe composition, described cylinder is arranged on reciprocation pipe by its two end cap, and connect with tail pipe, cylinder is connected with support to support, the rear and front end of described cylinder covers and has annular groove, be tightly connected respectively by O RunddichtringO between annular groove two ends and reciprocation pipe, between described annular groove and reciprocation pipe, be respectively equipped with guidance tape.
Further, the gap of 0.1-0.2mm is left at described annular groove and guidance tape two ends.
Further, the thickness of described guidance tape is 2-4mm.
Beneficial effect of the present invention is:
The present invention designs and produces simply, easy to operate, good concentricity, good airproof performance, and flexible reciprocation pipe can not be caused to sink, and convenient processing, can not damage 0 type circle by pressure, can not cause the gas leak phenomenon that leaks, and makes Zheng health check-up Ding Installed and puts perfection.Guidance tape in the present invention has the advantages such as anti-wear performance is good, long service life, ejector sleeve resistance are little.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1. support, 2. guidance tape, 3. front end end cover, 4.O RunddichtringO, 5. reciprocation pipe, 6. cylinder, 7. rear end cap, 8. tail pipe.
Embodiment
Below by embodiment and accompanying drawing, the invention will be further described.
Embodiment: as shown in Figure 1, the present invention includes cylinder 6, the reciprocation pipe 5 of suit and the expansion bend cylinder body of tail pipe 8 composition, described cylinder 6 is arranged on reciprocation pipe 5 by its two end cap, and connect with tail pipe 8, cylinder 6 is connected with support 1 to support, the forward and backward two end cap 3,7 of described cylinder 6 has annular groove, is tightly connected respectively by O RunddichtringO 4 between annular groove two ends and reciprocation pipe 5, between described annular groove and reciprocation pipe 5, is respectively equipped with guidance tape 2.
The gap of 0.1-0.2mm is left at described annular groove and guidance tape 2 two ends.The thickness of described guidance tape 2 is 2-4mm.
The present invention is by using guidance tape 2 dead center, and guidance tape 2 respectively arranges 1 at expansion bend cylinder body two ends, and reciprocation pipe 5 held by guidance tape 2, and such reciprocation pipe 5 contacts with 0 type circle 4, does not contact with any position of cylinder 6 cylinder body, can not cause sinking and drainage.And reciprocation pipe 5 and the concentricity of cylinder 6 cylinder body can be ensured, meanwhile, reciprocation pipe 5 can not be caused to sink and press less than 0 type circle, would not the gas leak phenomenon that leaks be caused.
