At present, the airtight survey instrument of vapour-pressure type on market is all checkout equipment, its cost is higher, and carry comparatively inconvenient, some only need detect the qualified product of atmospheric pressure value, do not need very high accuracy requirement, buy an equipment, cost of idleness, time vacuum pipe is long, because of the mobile inconvenience of equipment, cause detecting inconvenience.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of survey instrument being convenient to detect vacuum pipe air pressure inside value.
For achieving the above object, the utility model provides following technical scheme:
A kind of vacuum pipe vapour-pressure type survey instrument, comprising:
One head end fixture, for the head end mouth of pipe of containing vacuum pipeline;
One tail end fixture, for the tail end mouth of pipe of containing vacuum pipeline;
Wherein, the end face of head end fixture side is arranged with adapter coupling, adapter coupling inside has detection chambers, described head end fixture is active in adapter coupling inside, and be connected with the inner wall sealing of adapter coupling, described head end fixture is provided with air admission hole and rain glass, and described air admission hole one end communicates with detection chambers, and described head end fixture has chute rain glass being communicated to detection chambers.
By adopting technique scheme, when needing the atmospheric pressure value measuring vacuum pipe inside, by tail end fixture and head end fixture, vacuum pipe is sealed, head end fixture has an air admission hole, send into gas by external unit, arrive barometric position after gas gassy by chute, whether rain glass detects inside and leaks gas or whether reach qualified standard, this survey instrument simple economy is practical, and is easy to carry about with one.
The utility model is set to further: the xsect of described head end fixture is T-shaped to be had one and grow part, the xsect of described detection chambers is convex and has an outshot, described head end fixture to grow part sheathed and pass the projection of described detection chambers.
By adopting technique scheme, convex and T-shaped head end fixture and the adapter coupling of can making produce spacing, and structure is simple, avoids increasing other position limiting structures again.
The utility model is set to further: described head end fixture is provided with gasket seal with the place of abutting of adapter coupling.
By adopting technique scheme, gasket seal further ensures inner sealing, and when ensureing air admission hole air inlet, other places do not produce gas leakage, improves and measures precisely.
The utility model is set to further: what described chute was positioned at head end fixture grows portion outboard, and described rain glass is fixed on adapter coupling extends and abuts on chute.
By adopting technique scheme, rain glass is fixed on adapter coupling to be convenient to fix, and avoids rain glass simultaneously and moves with head end fixture, need to open chute at adapter coupling, impact sealing.
The utility model is set to further: the xsect of described tail end fixture is also T-shaped, and this place also has an adapter coupling and the gasket seal for the abutting place that seals tail end fixture and adapter coupling.
By adopting technique scheme, tail end fixture can be connected with vacuum pipe easily and seal.

Embodiment
Referring to figs. 1 through Fig. 5, a kind of vacuum pipe vapour-pressure type of the utility model survey instrument embodiment is described further.
A kind of vacuum pipe vapour-pressure type survey instrument, comprise a head end fixture 1, for the head end mouth of pipe of containing vacuum pipeline, a tail end fixture 8, for the tail end mouth of pipe of containing vacuum pipeline.
The end face of head end fixture 1 side is arranged with adapter coupling 2, and adapter coupling 2 inside has detection chambers 5, and it is inner that head end fixture 1 is active in adapter coupling 2, and be connected with the inner wall sealing of adapter coupling 2.
Head end fixture 1 is provided with air admission hole 3 and rain glass 4, air admission hole 3 one end communicates with detection chambers 5, and the other end communicates with the external world.
The xsect of head end fixture 1 is T-shaped, the xsect of detection chambers 5 is convex, head end fixture 1 to grow part sheathed and pass the projection of detection chambers 5, convex and T-shaped head end fixture 1 and the adapter coupling 2 of can making produce spacing, structure is simple, avoids increasing other position limiting structures again.
Head end fixture 1 is provided with gasket seal with the place of abutting of adapter coupling 2, and gasket seal further ensures inner sealing, and when ensureing air admission hole 3 air inlet, other places do not produce gas leakage, improves and measures precisely.
