I. Overview:
ZCRB series gas emergency shut-off valve is a new gas pipeline projects supporting the safety device, mainly used in the following situations:
1. And combustible gas leak detection equipment is connected. When the instrument detects combustible gas leakage, automatically and quickly close the main supply gas valve, cut off the gas supply, in time to stop a vicious accident.
2. And thermal equipment limit temperature (or pressure) safety controller connected. When the device within the detection point of temperature or pressure exceeds a set limit value, the automatic fast closing gas valve, stop the fuel supply.
3. With high-rise buildings connected to the central fire alarm system. When the building when the fire occurred, automatically cut off the building's gas supply, to prevent the gas explosion occurred.
4. In the plant's gas supply to the city or within a set BZCK gas pipeline emergency shut-off valve, can be concentrated in the central control room control, long-distance remote control, emergency shut down at the scene of the pipeline gas supply.
5. Reliable technical performance; extremely low load of the loss; high safety performance; excellent energy saving performance; quickly cut off the performance of the five characteristics of this series.
Second, the valve features
◆ valve in their daily work in a normally open state, solenoid valve coil is energized, do not consume energy
◆ When an accident occurs, the valve coil instantaneous power, triggered by rapid valve closure, and access to self-lock status. At this point, even if removed
◆ When the staff finished with the accident, artificial re-open the valve, gas supply will resume.
◆ valve with pilot operated valve flap to open easily, even if the pressure is also very easy to open up 6bar, diameter greater than DN125, lever handle, valve to switch to labor-saving, fast.
Note: According to customer requirements to provide power off emergency shut-off valve normally closed
Third, technical parameters:
1, applies to gas, natural gas and liquefied petroleum gas.
2, valve specifications: screw connection G1 / 2 ", G3 / 4", G1 "; flange connection DN25 ~ 350
3, working pressure: 0.5bar ~ 6bar
4, electrical protection class: CEI IP65/IP67
5, explosion-proof grade: Eexm Ⅱ T4 / Eexm Ⅱ T5
6, voltage and electric power: AC AC220V, 50Hz/14V; DC DC12V/8.5W, DC24V/8.5W
7 operating factor: continuous output or pulse type
8, the electrical connections: plug-in (regardless of positive and negative)
9, the coil power: ≤ DN100, 20 ℃ when the exchange of AC220V, 50Hz/24VA DC DC24V, / 24W coil Model: MF-1 (2 ≥ DN100, 20 ℃ when the exchange of AC220V, 50Hz/90VA DC DC24V, / 85W coil Model: ZCLF-1 (2)
10, the working environment temperature: -15 ~ 60 ℃
11, sealing materials: NBR rubber
12, Body Material: Brass, stainless steel, carbon steel
13, the valve closing time: less than 1 second
14, Quality Certification: ISO9001
Fourth, the process of manual reset operation
When the valve is cut off, pipe leak troubleshooting, staff need to manually reset, manual reset lever pulling force up to hear "cracking" bang, shows the valve fully open. At this point, even if let go will not be cut off. (Except to give the valve coils).
Note: The solenoid valve must be manually reset when the operation coil power.
