1 theme content and suitable scope
This standard set bittern acting alkyl the performance demand of a powerful person of extinguishing system choice and experiment method.
This standard applies to bittern acting alkyl 1301 with bittern acting alkyl 1211 extinguishing system select a powerful person.
2 cite standard
Demand of performance of a powerful person of extinguishing system container mixes acting alkyl of GB 795 bittern experiment method
GB 4981 is industrial the compression test of valve
3 term
Driving force: Actuating device chooses the force that place of a powerful person brings to bear on for open. The greatest actuating pressure: Fill container outfit extinguishing chemical, fill pressure, and park is undermentioned in 3 kinds of temperature taller person, right now container balances pressure mediumly. A. 50 ℃ ; B. Highest use temperature; C. The manufactory is recommended (or regulation) top job temperature.
4 technologies ask
The requirement of 4.1 choices a powerful person
Selecting a powerful person is device is taking the place of with bittern in the plumbing that fluid photograph gives priority to alkyl extinguishing chemical, its action is: With acting alkyl of a bittern extinguishing system protects interval of many fire prevention, when among them when interval of a fire prevention produces fire, by the choice a powerful person chooses the passageway that extinguishing chemical overshoots. The design that selects a powerful person should accord with bittern acting alkyl the real requirement that extinguishing system changes a circumstance to fall in shake, should not appear misoperation.
Bounds of 4.2 jobs temperature
The working temperature end that selects a powerful person is, 20 ℃ arrive 50 ℃ , need actually when the basis, when its design working temperature to exceed this limit, answer to come out number of its applicable working temperature scope.
4.3 material
Choice a powerful person and its interior spare parts are usable anticorrosive metallic stuff is made, also can use the other metalloid data that accords with this standard performance demand to make. But must want to have enough strength, can bear the proof pressure that this standard asks and experiment temperature.
5 function ask
5.1 intensity ask
5.1.1 pressure test press this standard 6.2.1 experiment method, have a test with 1.5 times the greatest actuating pressure, valve and its accessory must not have be out of shape, leakage, crackle or attaint.
5.1.2 exceed control a demand
By this standard 6.2.2 experiment method has a test with the greatest actuating pressure of 3 times, valve must not have burst appearance.
5.2 sealing ask
Press this standard 6.4 experiment method, the 1.1 times the greatest actuating pressure that presses a powerful person has a test, a powerful person reachs the exit of its accessory, the leakage fort of water must not exceed 3.0mL / Min.
5.3 jobs dependability experiments
Choice a powerful person has a test 6.3 times by this standard, the behavioral Ying Ling of valve is vivid, accurate, reliable, must not give the damage that shows any breakdown and structure (the component attaint when valve works normally does not list) here.
