The lower shell body is hemispherical, and a water inlet hole which is connected with a water supply branch pipe in the geographic system is formed in the center of the bottom of the lower shell body. The upper shell body is in a frustum shape, the edge of a lower port of the upper shell body is connected to the edge of an upper port of the lower shell body through a bolt, and thus an air collection chamber is formed in the lower shell body and the upper shell body. Heat exchange media are contained in the air collection chamber. The outer surface of the lower portion of the exhaust pipe is mounted on the inner surface of an upper port of the upper shell body. The brass ball valve is mounted at an upper port of the exhaust pipe, and the brass ball valve is in an opening state during normal operation. The hollow plastic ball is placed in the air collection chamber and floats on the liquid surface of the heat exchange media. By means of the automatic air valve for the geographic system, air in the geographic system can be automatically exhausted, and therefore the refrigerating and heating capacity of an air-conditioning system can be guaranteed. Moreover, the automatic air valve for the geographic system is reasonable and simple in structural design, convenient to mount, use and maintain and low in cost.

Fig. 1 is a kind of embedding system structural representation of prior art.As shown in Figure 1, described embedding system comprises heat pump unit 1, embedding system circulating water pump 2, buried water knockout drum 3, buried water-collecting machine 4 and multiple ground heat exchanger 5; Wherein the top of buried water knockout drum 3 is provided with a water intake 8, and bottom is provided with multiple water outlets 9; The top of buried water-collecting machine 4 is provided with a water outlet 10, and bottom is provided with multiple water intakes 11; Multiple ground heat exchangers 5 are divided into some groups, every group is connected with each ground heat exchanger 5 feed-water ends by same Cheng Fangfa by a horizontally disposed water supply arm 12, is connected by a horizontally disposed return branch 13 with a water intake 11 on buried water-collecting machine 4 simultaneously; Heat pump unit 1 by pipeline respectively with buried water knockout drum 3 on water intake 8 and the water outlet 10 on buried water-collecting machine 4 join; Embedding system circulating water pump 2 is arranged on the pipeline between heat pump unit 1 and buried water-collecting machine 4.
But there is following point in the embedding system of this prior art:
In embedding system, always there is a certain amount of air.1, air source: unavoidably can have air in ground heat exchanger 5 when system is installed, be difficult to get rid of clean when system water-filling.In addition, also can bring a small amount of bubble when embedding system moisturizing into, long-term accumulation forms aeroembolism.2, air harm: these aeroembolisms can form aeroebolism at water supply arm 12 ends under current impetus in embedding system, aeroebolism will stop flowing of Guan Zhongshui, thereby make the water in buried tube heat exchanger 5 partly not flow and lose exchange capability of heat, result causes whole embedding system heat transfer effect decay, thereby affects refrigeration, the heat capacity of air-conditioning system.And along with the continuous accumulation of air, the quantity of aeroebolism also can strengthen, this negative effect of a specified duration is increasing.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of embedding system automatic control pressure vent of corrosion-resistant, simple in structure, successful.
In order to achieve the above object, the embedding system that the utility model provides comprises lower case, upper body, hollow plastic pellet, outlet pipe and copper ball valve with automatic control pressure vent; Wherein lower case is hemisphere, and bottom centre is formed with a water inlet being connected with the arm that supplies water in embedding system; Upper body is taper type, and its lower end mouth edge is bolted the upper end-hole edge in lower case, forms a collection chamber thus in the inside of lower case and upper body, is contained with heat transferring medium in collection chamber; The lower external face of outlet pipe is arranged on the upper end-hole internal surface of upper body; Copper ball valve is arranged on the upper end-hole place of outlet pipe, while normally operation in opening state; Hollow plastic pellet is placed in collection chamber, and swims on heat transferring medium liquid level.
The diameter of described hollow plastic pellet is greater than the internal diameter of outlet pipe.
Described embedding system is arranged on water supply arm end with automatic control pressure vent.
The embedding system that the utility model provides can be discharged the air in embedding system automatically with automatic control pressure vent, therefore can guarantee refrigeration, the heat capacity of air-conditioning system, and reasonable in design, simple, install and use easy to maintenance, cost is low.

Embodiment
Embedding system the utility model being provided below in conjunction with the drawings and specific embodiments is elaborated with automatic control pressure vent.The parts identical with prior art adopt identical drawing reference numeral, and omit the explanation that it is carried out.
As shown in Fig. 2-Fig. 6, the embedding system that the utility model provides comprises lower case 14, upper body 15, hollow plastic pellet 16, outlet pipe 17 and copper ball valve 18 with automatic control pressure vent; Wherein lower case 14 is hemisphere, and bottom centre is formed with a water inlet 19 being connected with the arm 12 that supplies water in embedding system; Upper body 15 is taper type, and its lower end mouth edge is bolted the upper end-hole edge in lower case 14, forms a collection chamber thus in the inside of lower case 14 and upper body 15, is contained with heat transferring medium in collection chamber; The lower external face of outlet pipe 17 is arranged on the upper end-hole internal surface of upper body 15; Copper ball valve 18 is arranged on the upper end-hole place of outlet pipe 17, while normally operation in opening state; Hollow plastic pellet 16 is placed in collection chamber, and swims on heat transferring medium liquid level.
The diameter of described hollow plastic pellet 16 is greater than the internal diameter of outlet pipe 17.
Described embedding system is arranged on water supply arm 12 ends with automatic control pressure vent.
The embedding system now the utility model being provided is described below by automatic control pressure vent working principle: in embedding system running, copper ball valve 18 is all the time in opening state, and the heat transferring medium supplying water in embedding system in arm 12 enters the water inlet by lower case 14 19 in collection chamber.In the time there is air in embedding system, heat transferring medium in collection chamber is discontented, and at this moment the air in embedding system can discharge through copper ball valve 18 by outlet pipe 17, in this process, liquid level in collection chamber constantly rises, and the position of hollow plastic pellet 16 also will increase; After air is emptying, hollow plastic pellet 16, by the top of floating to collection chamber, is finally blocked outlet pipe 17 lower end mouth, thereby stops the heat transferring medium in embedding system to enter in outlet pipe 17.In addition, when embedding system is safeguarded, copper ball valve 18 can be closed.
