Abstract

A hydraulic test mounting device for pipe samples comprises a locating guide pole, an upper choke plug, a lower chock plug, an upper bracket and a hydraulic cylinder. Wherein, a lower end of the locating guide pole is fixed on the lower choke plug. The upper choke plug is correspondingly arranged above the lower choke plug and positioned on the locating guide pole and can move up and down along the locating guide pole. In addition, at least one seal groove is respectively arranged on the upper and lower choke plug. The upper choke plug is provided with an injection hole to make a pipe sample connected with outside. An upper mounting plate is fixed at an upper end of the locating guide pole. Besides, the hydraulic cylinder is arranged on the upper mounting plate. The upper choke plug is arranged at a front end of a piston rod of the hydraulic cylinder. With a rational and compact structure, the utility model conveniently mounts pipe samples by elevating a choke plug through a hydraulic cylinder. Due to seal grooves of various sizes on the choke plug, pipe samples with different sizes can be mounted, thus mounting pipe samples of varied sizes and greatly increasing working efficiency. The utility model is particularly suitable for PVC pipes.

Description

Tubular product sample hydraulic test erecting device

One, technical field

The utility model relates to the device that the tubular product sample hydraulic test is installed, and is a kind of tubular product sample hydraulic test erecting device, is specially adapted to the pvc pipe material.

Two, background technology

The plug at the sample two ends of tubing hydraulic test machine all adopts artificial installation at present, operating difficulties, and inefficiency, thus cause the experimental data feedback cycle long, and do not have many specifications seal groove on the plug, can not adapt to the installation of different size tubular product sample.

Three, summary of the invention

The utility model provides a kind of tubular product sample hydraulic test erecting device, has overcome the deficiency of above-mentioned prior art, and its reasonable and compact in structure is not only easy to use, and has improved work efficiency greatly.

The technical solution of the utility model realizes by following measure: a kind of tubular product sample hydraulic test erecting device comprises positioning guide column, upper plug head, lower end cap, upper bracket plate and hydraulic cylinder; The lower end of positioning guide column is fixedly mounted on the lower end cap, above lower end cap to upper plug head should be arranged, upper plug head is installed on the positioning guide column and can moves up and down along positioning guide column, on lower end cap and upper plug head, be no less than one seal groove, have on the upper plug head to make tubular product sample and the extraneous notes that communicate press mouth having; The upper bracket plate is fixedly mounted on the upper end of positioning guide column, and hydraulic cylinder is fixedly mounted on the upper bracket plate, and upper plug head is fixedly mounted on the piston rod front end of hydraulic cylinder.

Be further optimization and/or improvements below to above-mentioned technical solutions of the utility model:

In the above-mentioned seal groove O-ring seal can be arranged.

But above-mentioned O-ring seal O RunddichtringO.

Can have on the above-mentioned upper plug head and can make tubular product sample and the extraneous exhausr port that communicates.

Above-mentioned lower end cap can be fixedly mounted on the support.

The utility model reasonable and compact in structure can promote plug by hydraulic cylinder easily the pipe fitting sample is installed, and because on the plug many specifications seal groove is arranged, so the tubular product sample of different size between the Φ (110-400) can be installed; The sample installation rate also than original raising 2.5-3 doubly; So not only can carry out the installation of different size tubular product sample easily, and improve work efficiency greatly, be specially adapted to the pvc pipe material.

Four, description of drawings

Accompanying drawing 1 is looked the sectional structure synoptic diagram for the master of the utility model most preferred embodiment;

Coding in the accompanying drawing is respectively: 1 is hydraulic cylinder, and 2 is the upper bracket plate, and 3 for annotating the pressure mouth, and 4 is upper plug head, and 5 is O-ring seal, and 6 is tubular product sample, and 7 is positioning guide column, and 8 is lower end cap, and 9 is support, and 10 is exhausr port, and 11 is seal groove, and 12 is piston rod.

Five, embodiment

The utility model is not subjected to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.

Below in conjunction with embodiment and accompanying drawing the utility model is further described:

As shown in Figure 1, this tubular product sample hydraulic test erecting device comprises positioning guide column 7, upper plug head 4, lower end cap 8, upper bracket plate 2 and hydraulic cylinder 1; The lower end of positioning guide column 7 is fixedly mounted on the lower end cap 8, above lower end cap 8 to upper plug head 4 should be arranged, upper plug head 4 is installed on the positioning guide column 7 and can moves up and down along positioning guide column 7, on lower end cap 8 and upper plug head 4,, have on the upper plug head 4 to make tubular product sample 6 and the extraneous notes that communicate press mouth 3 to the seal groove 11 that is no less than should be arranged; Upper bracket plate 2 is fixedly mounted on the upper end of positioning guide column 7, and hydraulic cylinder 1 is fixedly mounted on the upper bracket plate 2, and upper plug head 4 is fixedly mounted on piston rod 12 front ends of hydraulic cylinder 1.

Can according to actual needs aforementioned tubes sample hydraulic test erecting device be made further optimization and/or improvements:

As shown in Figure 1, for the sealing of enhanced leaktightness groove 11, in the seal groove 11 O-ring seal 5 can be arranged.

As shown in Figure 1, because tubular product sample 6 generally is circular, so O-ring seal 5 O RunddichtringO preferably.

As shown in Figure 1, before hydraulic test begins, for the ease of the discharge of air in the tubular product sample 6; Can have on the upper plug head 4 and can make tubular product sample 6 and the extraneous exhausr port 10 that communicates.

As shown in Figure 1, in order to increase stability of the present utility model, lower end cap 8 can be fixedly mounted on the support 9.

Above technical characterictic has constituted most preferred embodiment of the present utility model, and it has stronger adaptability and best implementation result, can increase and decrease non-essential technical characterictic according to actual needs, satisfies the demand of different situations.

Use of the present utility model: before hydraulic test, earlier tubular product sample 6 is intercepted certain-length by standard, 45 degree chamferings are done at two ends, elder generation is with hydraulic open before installation, upper plug head 4 is risen, then tubular product sample 6 is put into the seal groove 11 of lower end cap 8 corresponding specifications, and tubular product sample 6 hollow space waters are full of, air in the tubular product sample 6 is discharged tubular product sample 6 by exhausr port 10, using hydraulic cylinder 1 that upper plug head 4 is pressed down until the two ends of tubular product sample 6 all embeds in the seal groove 11 of upper plug head 4, reach good sealing effectiveness, annotating a pressure efferent duct of pressing mouth that the hydraulic test machine is installed, begin to carry out hydraulic test subsequently.
