3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
Symmetrical seated valves symmetricseatedvalve
Along an axis through the body surface at both ends, in the middle on both sides of the opening and closing member has the same internal structure size of the valve.
3.2
Asymmetric seat valve asymmetricseatedvalve
By the end faces along the axis of the body, on either side of the center line having a valve opening and closing member is not the same internal structure.
4 Test Guidelines
4.1 Valve structure requirements
4.1.1 Symmetric valve seat structure, performed only on either side of the fire resistance test.
4.1.2 Asymmetrical valve seat structure, shall be installed and the different flows were fire resistance test; only one valve in the first test
After the repair can be carried out after the repair in the opposite direction of the second fire resistance test.
4.1.3 one-way flow valve, the flow shall be designated fire resistance test.
4.1.4 valve in the fire resistance test can not be separated in fire protection.
4.1.5 If the valve is equipped with a pilot valve gearboxes, the test results with the gearbox valve can be verified without a gearbox.
4.1.6 In addition to manually operated gear box or the like of the operating mechanism of the valve driving apparatus of other types (such as electric, pneumatic or hydraulic means
Devices, etc.), there should be specific protective measures in this test, fire resistance test in a case such as the content of the test drive without assessment.
Pressure relief valve 4.2
4.2.1 Pressure relief devices during take-off from fire resistance tests, the test should be continued.
