Abstract
The utility model discloses a pressure testing bench comprising two supports. A transverse beam is arranged between the two supports, a pipeline is fixedly arranged on each of the supports positioned above the transverse beam, one end of each pipeline is sealed, and the opening ends of the two pipelines are opposite and are provided with a conical pressure top respectively; the two pipelines are respectively provided with a through hole, a pressure gauge is arranged on the through hole of one pipeline, and a valve is arranged on the through hole of the other pipeline. The pressure testing bench is simple in structure and high in measurement precision, is convenient in use, and has good airtightness as well as high strength and high corrosion resistance and durability as the pressure tops are made of polyurethane.
Description
Technical field
The utility model relates generally to the pressure detection field, relates in particular to a kind of pressure testboard.
Background technology
Whether pressure testboard is used for measuring the intrinsic pressure of spiral steel pipe, and spiral steel pipe is used for coal mining activity, and is very high to the pressure requirement, comes gaging pressure by this, can check product qualified, and present detection method is a lot, but all accurate not.
The utility model content
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of pressure testboard for measuring intrinsic pressure to be provided.
The utility model is achieved through the following technical solutions:
Pressure testboard, it is characterized in that: include two bearings, set up a crossbeam between two bearings, be positioned on two bearings of top of crossbeam and be installed with respectively a pipeline, the end sealing of pipeline, the openend of two pipelines is relative, the openend of two pipelines is respectively equipped with the pressure top of a taper, have a through hole on two pipelines, a tensimeter is installed on the through hole of a pipeline, a valve is installed on the through hole of another pipeline.
The other end of described valve is connected with gas-holder.
The material on described pressure top adopts polyurethane.
Principle of the present utility model is:
Spiral steel pipe places on the crossbeam, and the pressure contact of two tapers combines closely it at the two ends of spiral steel pipe, does not stay a slit.Open valve, gas injection in the pipeline, gas enters in the spiral steel pipe, enter in another pipeline, thereby tensimeter is measured its pressure again.
The utility model has the advantages that:
The utility model is simple in structure, easy to use, and measuring accuracy is high; And the material on pressure top is polyurethane, not only can well guarantee leakproofness but also very large intensity is arranged and corrosion resistance and durability with polyurethane.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, pressure testboard, include between 1, two bearing 1 of two bearings and set up a crossbeam 2, be positioned on two bearings 1 of top of crossbeam 2 and be installed with respectively a pipeline 3, the one end sealing of pipeline 3, the openend of two pipelines 3 is relative, and the openend of two pipelines 3 is respectively equipped with on 4, two pipelines 3 in pressure top of a taper and has a through hole, a tensimeter 5 is installed on the through hole of a pipeline, a valve 6 is installed on the through hole of another pipeline 3.
The other end of valve 6 is connected with gas-holder.
The material on pressure top 4 adopts polyurethane.
