KROM SCHRODER控制器TC4系列產(chǎn)品介紹
密封性控制TC在具有兩個安全閥的系統(tǒng)每次啟動之前或每次關(guān)閉之后檢查兩個閥的故障安全功能。
目的是找出其中一個燃?xì)忾y上不允許的泄漏并防止燃燒器啟動。另一個燃?xì)忾y繼續(xù)正常工作，并接管了燃?xì)夤?yīng)的安全切斷。
它用于工業(yè)熱處理設(shè)備，鍋爐和強制通風(fēng)燃燒器。
標(biāo)準(zhǔn)ISO 13577-2，EN 746-2和EN 676規(guī)定了對容量超過1200 kW的密封性控制（NFPA 86：從117 kW或400,000 Btu / h起，并帶有視覺指示器）。
如果使用密封性控制，則可以在一定條件下根據(jù)EN 746-2取消燃燒室的預(yù)吹掃。在這種情況下，系統(tǒng)必須排入安全區(qū)域。
TC 1V，TC 1C
緊密度控制TC 1V可以直接法蘭安裝到所有valVario控制上。所有尺寸只有一個版本。
TC 1C可以用于組合控件CG 1至3。提供了一塊安裝板。
TC 2和TC 4
密封控制裝置TC 2和TC 4可與任何公稱尺寸的電磁閥一起使用，這些電磁閥以啟動速度可快速打開或緩慢打開。通過使用附加的輔助閥，可以在沒有啟動率的情況下對氣動閥或緩慢打開的閥進(jìn)行密封性測試。
TC 2和TC 4還可在0至60°C（32至140°F）的溫度范圍內(nèi)直接將法蘭連接在一起的慢開電動閥VK達(dá)到DN 65。
提供用于安裝TC 2的適配器板。
TC 3
密封性控制TC 3是用于任何額定尺寸的快開和慢開燃?xì)怆姶砰y以及電動閥的通用設(shè)備。
氣密性測試是使用TC 3中安裝的閥門進(jìn)行的。
TC 4
密封性控制TC 4由檢測電路組成，可與系統(tǒng)分開安裝在控制柜中，外部壓力開關(guān)接管閥門之間的機械壓力測試。氣密性控制TC 4與氣體類型和進(jìn)氣壓力pu無關(guān)，并且在大測試量的情況下，可用于長達(dá)10分鐘的測試時間。
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.
