Description
Technical field
The utility model is related to the device whether a kind of easy detection pressure pipeline weld seam leaks.
Background technology
Pressure pipeline refers to all pipelines for bearing internal pressure or external pressure, regardless of medium in its pipe.Pressure pipeline is pipe
A part in road, pipeline is to convey, distribute, mix, separate, discharge, measure, control and prevent flow of fluid, by
Pipe, pipe fitting, flange, bolt connection, pad, valve, other component parts or pressure-containing parts and set of bearings into assembly.
It is essential in order to increase the welding between the length of pipeline, pipeline.The pressure pipeline of high length is to have many
Shorter pressure piping is formed by connecting, and is attached between two pressure pipings by connected modes such as welding, in pressure pipeline
After being worked long hours, aging easily occurs at the solder design of pressure pipeline, the pressure pipeline after aging is in the course of work
In can reveal, not only result in the waste of raw material, or even the safety in production of enterprise can be influenceed.
Existing pressure pipeline detection device typically all compare it is huge costly, for some unprofessional users its
Price can not be born.
Utility model content
For above-mentioned technical problem, the utility model provides a kind of pressure pipeline weld seam detection means, can surveyed
Whether test tube road commissure has leakage, and its is simple in construction, and transhipment is convenient.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is that a kind of pressure pipeline weld seam detects dress
Put, include the pressure testing part of ring-type, the pressure testing part inner ring surface is provided with annular groove, and the annular groove both sides are inlaid with close
Seal；Also include a connecting tube, described connecting tube one end is connected and sensible annular groove with pressure testing part, and the other end is provided with
With the tank connected joint of compressed air；Valve is provided with the connecting tube；Also include an air gauge, the air gauge connection
Between valve and pressure testing part；The pressure testing part is put together by the component of two semi-annular shapes；Described two components
One end is connected by bearing pin, and the other end is provided with the boss for connection, the boss and is provided with the screw run through.
As an improvement, it is provided with coil pipe between the air gauge and connecting tube.Instantaneous pressure is avoided to rush air gauge
It is bad.
As an improvement, it is provided with rubber sheet gasket on the raised head face.Increase the air-tightness between raised head face, from
And improve the accuracy of detection.
As an improvement, the sealing ring is 4, annular groove both sides is respectively in, for improving pressure testing part and quilt
Air-tightness between test tube part.
As a preferred embodiment, also including some bolts through anchor ring inside and outside pressure testing part.Prevent pressure testing part from turning
It is dynamic that test effect is impacted.
It is of the present utility model to be beneficial in that：Detection means with said structure, its is simple in construction, and detection process is fast
Victory is convenient.It is adapted to less demanding in field etc., and the occasion of precision instrument can not be carried uses.
