Abstract
The utility model relates to the design field of parts of a fluid heater, and discloses a gas water heater with an air exhausting device. The gas water heater with the air exhausting device comprises a heat exchange subassembly, a circulation pipeline, a water inlet pipeline and a water pump. The water inlet pipeline is communicated with the circulation pipeline through a T joint, and the water pump is arranged on the circulation pipeline. The gas water heater with the air exhausting device is characterized in that a composite joint is arranged on the circulation pipeline between the T joint and the water pump, and an air exhaust port is arranged on the composite joint, wherein the circulation pipeline comprises a coil pipe, a circulation water outlet pipe and a circulation water inlet pipe. The coil pipe is arranged on the heat exchange subassembly, the circulation water outlet pipe is communicated with one end of the coil pipe and the circulation water inlet pipe is communicated with the other end of the coil pipe. The T joint and the water pump are arranged on the circulation water inlet pipe. The gas water heater with the air exhausting device has the advantages that through the arrangement of the composite joint on the circulation water inlet pipe, gas in the circulation pipeline is effectively exhausted so that the water pump can be protected, and the service life of the water pump is prolonged.
Description
Technical field
The utility model relates to the parts design field of fluid heater, relates in particular to the drainage exhaust device of gas heater.
Background technology
Gas heater has obtained in house, hotel, hotel more and more widely using, especially in the larger occasion of some heat demand, on gas heater also with the hot water circuit pipeline; This just makes in the installation and use procedure of water heater, inevitably occurs air in the hot water circuit pipeline.
Yet, be not specifically designed to the device of exhaust in existing gas heater inner loop pipeline structure, if there is gas to exist in water heater inner loop pipeline, will cause water pump the idle running situation to occur, water pump is easily damaged, affect the water pump life-span.In addition, the existence of air can cause also that in circulation line, current not smoothly, affect the use of system.
Summary of the invention
For the defective that exists in prior art, the purpose of this utility model is to develop the gas fired water heater of a kind of water pump long service life, good exhaust effect.
For reaching above purpose, the utility model adopts following technical scheme.
A kind of gas heater with exhaust apparatus, comprise: heat exchanger section dress, circulating line, the inlet channel that is communicated with circulating line by three-way connection, and be arranged on water pump on circulating line, it is characterized in that, be connected with composite-joint on the circulating line between three-way connection and water pump, described composite-joint is provided with exhaust outlet.
As with improvement, described circulating line comprises and is arranged on the coil pipe that heat exchanger section loads onto, the recycling outlet that is communicated with coil pipe one end, and the circulation water inlet pipe that is communicated with the coil pipe other end; Described three-way connection and water pump are arranged on the circulation water inlet pipe.
As with improvement, described exhaust outlet is provided with exhaust pipe assembly, and described exhaust pipe assembly is provided with venting ball valve.
As with improvement, the upper end of described composite-joint is provided with to control the crossover sub of composite-joint water outlet direction.
Compared with prior art, the beneficial effect that the utlity model has is: by on the circulation water inlet pipe, composite-joint being set, can effectively gas in circulating line be discharged, water pump is protected, extend the water pump life-span.Simultaneously, composite-joint adopts three-way connection, and the composite-joint upper end arranges crossover sub, facilitates water, gas in the controlled circulation water pipe to discharge direction, and is simple in structure, good exhaust effect.

The specific embodiment
For further setting forth essence of the present utility model, by reference to the accompanying drawings the specific embodiment of the present utility model is described as follows.
As Figure 1-Figure 4, a kind of gas heater with exhaust apparatus that the present embodiment provides, comprise: heat exchanger section fills 1, circulating line 2, the inlet channel 4 that is communicated with circulating line 2 by three-way connection 3, and be arranged on water pump 5 on circulating line 2, it is characterized in that, be connected with composite-joint 6 on the circulating line 2 between three-way connection 3 and water pump 5, described composite-joint is provided with exhaust outlet 7.This exhaust outlet 7 is provided with exhaust pipe assembly 8, and described exhaust pipe assembly 8 is provided with venting ball valve 9.
Wherein, described circulating line 2 comprises that being coiled in heat exchanger section fills coil pipe on 1, the recycling outlet that is communicated with coil pipe one end, and the circulation water inlet pipe that is communicated with the coil pipe other end; Described three-way connection and water pump all are arranged on the circulation water inlet pipe.
In the present embodiment, described composite-joint 6 is three-way connection, as shown in Figure 2.Be the discharge of gas in better controlled circulation pipeline 2, the upper end of described composite-joint 6 is provided with to control the crossover sub 10 of composite-joint 6 water outlet directions.That is, during normal operation, crossover sub 10 conductings; During exhaust, crossover sub 10 is closed, and allows water is gentle discharges from exhaust outlet 7.
Particularly, during real work, cold water enters circulating line from inlet channel, circulating-heating constantly under the effect of water pump and heat exchanger section dress.When having air in circulating line, open drainage ball valve, like this, the air in circulating line just can with ducted water together, discharge through drain assembly and drainage ball valve; And then reach the purpose of exhaust.
A kind of gas heater with exhaust apparatus that the present embodiment provides by on the circulation water inlet pipe, composite-joint being set, can effectively be discharged gas in circulating line, and water pump is protected, and extends the water pump life-span.Simultaneously, composite-joint adopts three-way connection, and the composite-joint upper end arranges crossover sub, facilitates water, gas in the controlled circulation water pipe to discharge direction, and is simple in structure, good exhaust effect.
The above specific embodiment has been described in detail essence of the present utility model, but can not limit protection domain of the present utility model with this.Apparently, under the enlightenment of the utility model essence, the art those of ordinary skill also can carry out many improvement and modification, within it should be noted that these improvement and modification all drop on claim protection domain of the present utility model.
