The specific embodiment
For technology contents of the present utility model, feature and effect being had more specifically, understand, existing in conjunction with illustrated embodiment, details are as follows:
As shown in Figure 2, the air-conditioning system hot and cold water internally piloted valve leakage detection apparatus of the present embodiment, includes:
Electric check valve, is arranged on the arrival end of hot water or cold water's pipeline, before hot water or cold water's internally piloted valve, for shutting at hot water or cold water's internally piloted valve, while occurring to leak, automatically blinds off a line, and cuts off current;
Microswitch, is arranged on the closed position of hot water or cold water's internally piloted valve, for detection of the state (open or cut out) of hot water or cold water's internally piloted valve;
Water flow switch, is arranged on the hot water or cold water's pipeline between hot water or cold water's internally piloted valve and air-conditioning system, for detection of the streamflow regime in pipeline (mobile or static);
Acoustic-optic alarm, comprises alarm lamp and loudspeaker, and this acoustic-optic alarm has auto-lock function, for shutting at hot water or cold water's internally piloted valve, while occurring to leak, sends sound and light alarm self-locking;
Control circuit, is electrically connected with electric check valve, microswitch, water flow switch and acoustic-optic alarm respectively, for detection of the leak condition of hot and cold water internally piloted valve, controls electric check valve and acoustic-optic alarm.
The detailed circuit diagram of control circuit as shown in Figure 3, mainly consists of 5 loops that are connected in parallel to each other, and wherein, loop 1 is in series with microswitch contact X1 and the time relay
loop 2 is in series with water flow switch contact X2, time relay contact T1 and leak condition relay
loop 3 is in series with leak condition relay contact A1 and electric check valve relay
after loop 4 leak condition relay contact A1 and 3 parallel connections of alarm relay contact A again with SR RST and alarm relay
series connection, connects with alarm relay contact A 3 after alarm lamp RL and buzzer BZ parallel connection in loop 5.
Below the operation principle of this air-conditioning system hot and cold water internally piloted valve leakage detection apparatus is elaborated, shown in Figure 3:
When hot water or cold water's internally piloted valve adjust flux, the indicator of internally piloted valve spool position is not touched microswitch, and air-conditioning system hot and cold water internally piloted valve leakage detection apparatus is failure to actuate.
When hot water or cold water's internally piloted valve is closed, the indicator of internally piloted valve spool position touches microswitch, 01 microswitch contact, loop X1 closure, the time relay
adhesive after time delay (30s), T1 closure in 02 loop:
If now internally piloted valve can shut, water flow switch contact X2 is not closed, 02 not conducting of loop, and this internally piloted valve leakage detection apparatus is still failure to actuate;
If now internally piloted valve cannot shut, water flow switch contact X2 closure, 02 circuit closed, leak condition relay
adhesive.
Leak condition relay
after adhesive, the electric check valve relay in 03 loop
also adhesive, electric check valve cuts out, and blocks current, prevents energy loss (but after internally piloted valve is opened, X1 is not closed due to microswitch contact, therefore electric check valve also can be opened, and does not affect the regulatory function of internally piloted valve).
Leak condition relay
after adhesive, the alarm relay in 04 loop
also adhesive self-locking, thus the alarm lamp RL in 05 loop lights with buzzer BZ and pipes, and facilitates operations staff to find fault herein.Complete to automatic valve maintenance as operations staff, internally piloted valve is pressed RST SR after can closing completely, reports to the police and just eliminates.
