Abstract
The invention relates to a method for solving a hydraulic pressure test of a pressure container. The pressure testing device is characterized in that a circular blind plate is arranged between water injection and exhaust pipe orifice flanges of the pressure testing device, a vertical hole communicated with a horizontal hole on the side surface of the blind plate is drilled in the center of the circular blind plate, and the horizontal hole of the blind plate is connected with a pressure guiding pipe. The invention effectively solves the problems of influence on strength test effect and labor and time consumption caused by incomplete exhaust of gas in pressure test equipment and narrow installation space in the hydraulic test, enables the hydraulic test to be simple and easy to implement, can be strictly executed according to the national standard ' pressure vessel safety inspection regulation ' in-use pressure vessel inspection regulation ', and is particularly suitable for hydraulic test of pressure vessels and pipelines.
Description
The present invention relates to a kind of method of the pressure container hydraulic testing.
Domestic present petroleum chemical industry pressure vessel, particularly cold exchange device and pipeline are in carrying out hydraulic testing process, after the water filling, the emptying fully of pressure testing device interior gas, influence the strength test effect, in addition, connecting pipe and blind flange are at an angle of 90 between test pump and the pressure testing apparatus body flange, therefore require to have than large space behind the apparatus body flange, when the space is narrow and small, must be artificially objects such as pipeline behind the apparatus body flange be removed, enlarging installing space, this method was not only time-consuming but also increased workload.According to examination, above problem also not preferably method solved.
The object of the invention provides a kind of method of the pressure container hydraulic testing.
The present invention is achieved in that a circular blind plate is set that the center of circular blind plate is drilled with a upright opening and communicates with the side lateral aperture, connects pressure guiding pipe at the blind plate lateral aperture between the water filling of pressure testing equipment, exhaust pipe mouth flange.This blind plate has not only solved the pressure testing device interior gas problem of emptying fully, has also solved simultaneously because of the narrow and small trouble that objects such as pipeline behind the apparatus body flange are removed of installing space.
Fig. 1 is the blind plate scheme of installation
Fig. 2 is the blind plate synoptic diagram
Be described further below in conjunction with accompanying drawing
Blind plate 4 of the present invention and upper-lower seal pad 3 together are installed between upper flange 1 and the lower flange 5, and sealing is installed by bolt 2 pretightning forces.
Blind plate is circular, and side lateral aperture 8, central vertical hole 6 and pressurized plane 7 are arranged, and adapter 9 is welded on the blind plate side with hole 8 coaxial cables.
The present invention efficiently solve pressure testing device interior gas that the hydraulic testing exists fully emptying and installing space narrow and small and cause influence strength test effect and time-consuming problem of taking a lot of work, use this method can make the hydraulic testing simple and easy to do, can carry out in strict accordance with national standard " using the pressure vessel inspection procedure " " the supervisory rules of pressure vessel safety ", the present invention is particularly suitable for pressure vessel and pipeline carries out the hydraulic testing.
