SE520805C2 - Method of testing and maintaining a safety valve - Google Patents

Abstract

The invention relates to a method for documentation of the testing and maintenance of a safety valve. In this method the valve is assigned an identity, which together with the test result, documentation on the servicing undertaken, any repairs carried out and certificate of approval from an authorised inspector is stored in a database accessible by means of a password. According to the invention the authorised inspector is assigned a password for the database for accessing the test result for the identified valve via the Internet and for entering on the database the certificate of approval for the said valve based on the test result from the database.

Description

25f 35 520 eos; »; §f Provided that the test shows that the valve in question meets the set requirements, a competent inspector 5 issues an approval, which under the identity belonging to the valve is stored in the database 4.

Testing, service and approval as well as storage in the database take place analogously in the other premises 2, 3 for valves 2a and Xa, respectively, it should be noted that the premises can be geographically at a considerable distance from each other.

With a password, authorized persons can access information stored in the database 4 regarding valves 1a, 2a and Xa.

In fi g 2, l, 2 and X again generally denote three rooms with valves 1a, 2a and Xa which are subjected to service lc, 2c, Xc and testing lb, 2b and Xb. The test data 1d, 2d and Xd are derived from the test, which with the identity belonging to the respective valve are stored in the database 4 in the same way as explained in connection with Fig. 1.

According to the invention, the competent inspector 5 is assigned a password to the database 4 for accessing the test result for each valve through its identity. In a known manner, the inspector compares test data with established criteria for approval of the respective valve.

If the inspector finds that the valve in question meets the criteria, the issuer issues an approval certificate and stores it in the database under the identity of the valve in question, as illustrated in Fig. 2. It should be noted that the inspector can be placed arbitrarily, for example in a sitting area. at home or in the car.

The communication with the database 4 takes place with a connectable connection via the Internet.

In order to issue an approval certificate for, for example, valve 2a, the inspector 5 establishes contact with the database 4, for example via the Internet, and by means of his password the inspector 5 obtains access to the memory space 4pb where test data for the valve 2a is stored.

These are compared with the mentioned criteria for approval and if the test data meet these, the inspector opens the memory space 4gb and enters the approval certificate. To his aid, the inspector 5 of course has a computer with a keyboard and a screen on which, in a manner known per se, a certificate form appears, which supports the entry of the approval certificate. 520 805 3 When the certificate of approval for valve 2a has been issued, the inspector can take on the next assignment without having to move.
