The ZSFC dry alarm valve is the water supply control valve of the thousand type sprinkler system. The valve is normally closed with pressurized gas in the pipeline system (also used to monitor the sealability of the pipe network). When the nozzle is opened, the gas in the pipe network drops rapidly, the valve opens, the water enters the pipe network system and is ejected from the open sprinkler head to perform the fire extinguishing function.
It is basically the same as the wet alarm valve. The difference is that the total pressure on the valve plate of the wet alarm valve is caused by the pressure of the pressurized water in the pipe network, while the dry alarm valve is from the water pressure in front of the valve and the pipe in the rear of the valve. The pressure of the pressurized gas is caused. The wet alarm valve has a delay, and the dry alarm valve has no delay.
ZST glass ball sprinkler head is a key component of automatic sprinkler system, which can be used to detect fire and extinguish fire by automatic sprinkler. It's widely used in fire protection in various types of civil or high-rise civilian and industrial buildings of light and moderate danger and serious danger protection areas. ZST sprinkler head executes national standard structure of GB5135.1-2003 Part 1: Sprinkler Head of Sprinkler System.
ZST glass ball sprinkler head is assembled from glass ball, copper alloy gold frame and seal. Spray head frame is precision forged by copper alloy with high strength, strong corrosion resistance, polishing chromium plating in surface. And a variety of specifications for users to choose; the glass ball (temperature sensing element) and sealing gasket are made of high quality imported material which is resistant to aging and corrosion. The glass ball has high strength, reliable action and fast reaction speed.
T-ZST15 series glass ball sprinklers are assembled from copper alloy frames, glass balls, ball seats, seals, splash plates, etc. They are beautiful in appearance and compact in structure.
Features are as follows:
1. The nozzle frame is made of copper alloy, which has high strength, strong corrosion resistance and polished chrome finish.
2, the temperature sensor glass ball uses German J0b company products, high strength, reliable operation, fast response. The nozzle adopts the assembly inspection line imported from Germany for production inspection, and the quality is reliable and stable. The seal has the characteristics of aging resistance and corrosion resistance.
