KROM SCHRODER控制器TC4系列产品介绍
密封性控制TC在具有两个安全阀的系统每次启动之前或每次关闭之后检查两个阀的故障安全功能。
目的是找出其中一个燃气阀上不允许的泄漏并防止燃烧器启动。另一个燃气阀继续正常工作，并接管了燃气供应的安全切断。
它用于工业热处理设备，锅炉和强制通风燃烧器。
标准ISO 13577-2，EN 746-2和EN 676规定了对容量超过1200 kW的密封性控制（NFPA 86：从117 kW或400,000 Btu / h起，并带有视觉指示器）。
如果使用密封性控制，则可以在一定条件下根据EN 746-2取消燃烧室的预吹扫。在这种情况下，系统必须排入安全区域。
TC 1V，TC 1C
紧密度控制TC 1V可以直接法兰安装到所有valVario控制上。所有尺寸只有一个版本。
TC 1C可以用于组合控件CG 1至3。提供了一块安装板。
TC 2和TC 4
密封控制装置TC 2和TC 4可与任何公称尺寸的电磁阀一起使用，这些电磁阀以启动速度可快速打开或缓慢打开。通过使用附加的辅助阀，可以在没有启动率的情况下对气动阀或缓慢打开的阀进行密封性测试。
TC 2和TC 4还可在0至60°C（32至140°F）的温度范围内直接将法兰连接在一起的慢开电动阀VK达到DN 65。
提供用于安装TC 2的适配器板。
TC 3
密封性控制TC 3是用于任何额定尺寸的快开和慢开燃气电磁阀以及电动阀的通用设备。
气密性测试是使用TC 3中安装的阀门进行的。
TC 4
密封性控制TC 4由检测电路组成，可与系统分开安装在控制柜中，外部压力开关接管阀门之间的机械压力测试。气密性控制TC 4与气体类型和进气压力pu无关，并且在大测试量的情况下，可用于长达10分钟的测试时间。
The tightness control TC checks the fail-safe function of both valves before each start-up or after each shut-down of a system with two safety valves.
The aim is to identify an inadmissible leak on one of the gas valves and to prevent burner start. The other gas valve continues working properly and takes over the safe shut-off of the gas supply.
It is used in industrial thermoprocessing equipment, on boilers and on forced draught burners.
Standards ISO 13577-2, EN 746-2 and EN 676 stipulate tightness controls for capacities over 1200 kW (NFPA 86: from 117 kW or 400,000 Btu/h in conjunction with a visual indicator).
Pre-purge of the combustion chamber can be dispensed with under certain conditions in accordance with EN 746-2, if a tightness control is used. In this case, the system must be vented into a safe area.
TC 1V, TC 1C
Tightness control TC 1V can be directly flangemounted to all valVario controls. There is only one version for all sizes.
TC 1C can be used for combination controls CG 1 to 3. An adapter plate is supplied for installation.
TC 2 and TC 4
Tightness controls TC 2 and TC 4 can be used with gas solenoid valves of any nominal size,which are quick opening or slow opening with start rate. It is possible to conduct a tightness test on pneumatically operated or slow opening valves without start rate by using additional auxiliary valves.
Slow opening motorized valves VK up to DN 65 which are directly flanged together can also be checked by TC 2 and TC 4 within a temperature range of 0 to 60°C (32 to 140°F).
An adapter plate is provided for installation of the TC 2.
TC 3
Tightness control TC 3 is a universal device for quick and slow opening gas solenoid valves of any nominal size as well as for motorized valves.
The tightness test is carried out with the valves installed in TC 3.
TC 4
Tightness control TC 4 consists of detection circuitry and can be installed in the control cabinet,separately from the system. An external pressure switch takes over the mechanical pressure test between the valves. Tightness control TC 4 is independent of gas type and inlet pressure pu and can be used for a test period of up to 10 minutes with a large test volume.
