Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the schematic diagram of control circuit of the present utility model.
The specific embodiment
The utility model will be further described below in conjunction with the drawings and specific embodiments.
The free temperature difference heat transmission equipment of free static pressure, as shown in Figure 1 and Figure 2, comprising support 11 and the heat exchanger 1 that is installed on the support 11, fixedly connected water inlet pipe 3 in the top of heat exchanger 1 and recycling outlet 4, fixedly connected adjutage 9 in the bottom of heat exchanger 1 and circulation water inlet pipe 8; Water intaking valve 2 is installed on the water inlet pipe 3, outlet valve 5 is installed on the recycling outlet 4, check-valves 7 is installed on the circulation water inlet pipe 8, drain valve 10 is installed on the adjutage 9; Circulation water inlet pipe 8, recycling outlet 4 all are connected with water circulating pump 6, and water inlet pipe 3, adjutage 9, recycling outlet 4, circulation water inlet pipe 8 all are communicated with heat exchanger 1; Water intaking valve 2 is connected by a cycling switch synchronously with drain valve 10; Outlet valve 5 is connected by the secondary cycle switch synchronously with check-valves 7; One time cycling switch is connected with the secondary cycle switch interlock.
In the utility model once the control circuit of circulation, secondary cycle as shown in Figure 3, water intaking valve 2, drain valve 10, outlet valve 5 and check-valves 7 are magnetic valve, water intaking valve 2 is connected in parallel with the Electromagnetic Control end of drain valve 10, forms the branch road that once circulates; The Electromagnetic Control end of outlet valve 5, check-valves 7 and water circulating pump 6 is connected in parallel, and forms the secondary cycle branch road; The branch road that once circulates is electrically connected with controller 12 by interlock switch 13 with the secondary cycle branch road.
This equipment in use, water circulating pump 6 is connected with heating system.Its operation principle is as follows: close outlet valve 5 and check-valves 7 by interlock switch 13, open water intaking valve 2 and drain valve 10, hot water enters the inner chamber of heat exchanger 1 by water inlet pipe 3, and the cold water that stores in heat exchanger 1 inner chamber is passed through adjutage 9 discharge; When the inner chamber that detects heat exchanger 1 when controller 12 is full of hot water, automatically control interlock switch 13 conversion work states, close water intaking valve 2 and drain valve 10, open outlet valve 5 and check-valves 7, water circulating pump 6 runnings, cold water in the water system is entered by circulation water inlet pipe 8 in the inner chamber of heat exchanger 1, simultaneously, the hot water in heat exchanger 1 inner chamber is transported to heating system by recycling outlet 4 discharges and by water circulating pump 6.When controller 12 detects when being full of cold water in heat exchanger 1 inner chamber, control interlock switch 13 conversion work states automatically, close outlet valve 5 and check-valves 7, open water intaking valve 2 and drain valve 10, enter next heat exchange circulation.
This equipment can be used Pressure gauge and thermometer in use, utilizes electronic control system to operate, and realizes unmanned, operation automatically, can accurately control, regulate temperature and pressure.Because once circulation and secondary cycle are distinguished intermittent work, the pressure differential of both sides and temperature difference all without any influence, are the free temperature difference heat transmission equipment of a kind of free static pressure to the operation of this device.
This equipment is mainly used in the heat exchange of systems such as heating, air-conditioning, floor heating.
