Abstract
The utility model provides a high and low temperature combined heating system and aims to solve the technical problem as follows: the prior high and low temperature combined closed-type heating system utilizes two electronic control valves and has low reliability in comparison of the situation that a valve is used. The high and low temperature combined heating system comprises a water supplying pipeline, a water returning pipeline and a booster pump, wherein the water returning pipeline includes a water mixing pipeline and a return net pipeline, the water supplying pipeline at the front end of a pressure increasing device is connected with a three-way type water mixing valve, and a branch of the three-way type mixed water valve is connected with the water mixing pipeline. The system can be applied to the high and low temperature combined heating system.
Description
Technical field
The utility model relates to a kind of high and low temperature mixing heating system, specifically is to use three way type to mix the high and low temperature mixing heating system of water valve.
Background technology
The water-line of the heating of high and low temperature mixing at present closed system is provided with water power control valve and booster by last water direction.Return pipe divides two-way, and one the tunnel is to mix water pipeline, receives between water power control valve and the booster, and mixing on the water pipeline has mixed water power control valve; Another road is back the webmaster line, receives in system's return pipe net.Control system is according to last coolant-temperature gage and the return water temperature set, the open degree of water power control valve and mixed water power control valve in the control, and direct absorption portion backwater is sneaked in the water, realizes energy-conservation purpose.
Summary of the invention
Said system has used two electric control valve reliabilities low, and the purpose of this utility model is to provide the high and low temperature mixing heating system of a valve of a kind of use.
The purpose of this utility model is achieved in that it comprises water-line, return piping and booster, wherein return piping comprises mixed water pipeline and returns the webmaster line, it is characterized in that: the water-line at increasing apparatus front end (pipeline before promptly boosting) connects the mixed water valve of three way type, and the branch road that three way type mixes water valve connects mixed water pipeline.Regulate three way type by control system and mix water valve, the absorption portion backwater is sneaked in the water.
Compared with prior art, the beneficial effects of the utility model are: it is kept to a valve with two valves in the system, has improved the reliability of system.
Description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Fig. 1 is a schematic diagram of the present utility model.
Fig. 2 is that the utility model is applied in the direct connection heating system schematic diagram that heats for high level, low-rise building simultaneously.
Fig. 3 is the another kind of system schematic that the utility model is applied in the direct connection heating that is high level, low-rise building heating simultaneously.
The specific embodiment
Referring to Fig. 1, high and low temperature mixing heating system comprises water-line 1 (solid line part), return piping 5 (dotted portion), radiator 4 and booster 3, water-line at booster front end (pipeline before promptly boosting) connects pressure-reducing valve 7 and the mixed water valve 2 of three way type successively, the branch road filling pipe end that three way type mixes water valve connects mixed water pipeline 51, connects pressure-reducing valve 6 on return piping.Regulate three way type by control system and mix water valve, two pressure-reducing valves pressure that will go up water and backwater is regulated consistently simultaneously, and the absorption portion backwater is sneaked in the water.All the other backwater are got back in system's return pipe net through returning webmaster line 52.
Referring to Fig. 2, it is that a thermal source is direct connection heating system schematic diagram high-rise, the low-rise building heating simultaneously, and the latter half wherein is the direct connection heating system of low-rise building heating, and it is identical with Fig. 1; The first half is the direct connection heating system of high rise building heating, two system's parallel connections, high-rise difference with low layer is to connect a pneumatic rapid cut-off valve 8 at height district return piping, backwater blocking-up in Jiang Gao district when being used for termination of pumping, prevent to puncture low district radiator, the pressure that it is Jiang Gao district backwater that pressure-reducing valve 6 also has individual effect lowers, and is incorporated into the power networks with low district backwater.
Referring to Fig. 3, it also is that a thermal source is direct connection heating system schematic diagram high-rise, the low-rise building heating simultaneously, with the difference of Fig. 2 is that it is earlier that high-rise direct connection heating system with the low-rise building heating is in parallel, again three way type is mixed water valve 2 and receive total upper hose, said increasing apparatus is the booster of two parallel connections.
Claims (4)
1. high and low temperature mixing heating system, comprise water-line, return piping and booster, wherein return piping comprises mixed water pipeline and returns the webmaster line, it is characterized in that: the water-line at the increasing apparatus front end connects the mixed water valve of three way type, and the branch road that three way type mixes water valve connects mixed water pipeline.
2. according to the described high and low temperature mixing of claim 1 heating system, it is characterized in that: three way type mixes the preceding termination pressure-reducing valve of water valve, connects pressure-reducing valve on return piping.
3. according to claim 1 or 2 described high and low temperature mixing heating systems, it is characterized in that: on return piping, connect pneumatic rapid cut-off valve.
4. according to claim 1 or 2 described high and low temperature mixing heating systems, it is characterized in that: said increasing apparatus is the booster of a booster or two parallel connections.
