Description

Technical Field

[0001] The utility model relates to the technical field of air source heat pump units, in particular to a water system exhaust device. Background Art

[0002] When installing an air source heat pump unit, an exhaust valve must be installed in the system to remove the excess air in the system and maintain the system pressure.

[0003] Traditional exhaust valves are installed in the water system when installing the unit. Traditional exhaust valves are installed in the water tank when installing the unit, or installed on the water pipe through a tee. The disadvantages of this method are as follows: 1. Installed in the water tank: A water tank with a reserved exhaust valve port must be purchased; 2. Installed on the water pipe: a. The installer must install it in a suitable place. b. The installation is troublesome and there is a risk of leakage. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a water system exhaust device, aiming to solve the existing technical problems.

[0005] To achieve the above purpose, the utility model provides a water system exhaust device, including

[0006] An exhaust pipe, which is vertically placed, with an exhaust component provided at its top, and a water inlet and a water outlet provided at its side and bottom respectively;

[0007] A water inlet pipe, which is horizontally placed and connected to the water inlet; and

[0008] A water outlet pipe, which is vertically placed and connected to the water outlet;

[0009] Wherein, the inner diameter of the exhaust pipe is more than 1.5 times that of the water outlet pipe.

[0010] Further, the exhaust component is an exhaust valve.

[0011] Further, the water inlet is located in the middle and lower part of the side of the exhaust pipe.

[0012] The beneficial effects of the utility model are reflected in:

[0013] The water system exhaust device of the utility model can more easily remove the air in the system; this structure is directly welded in the unit, greatly reducing the leakage risk; the position of the drain valve is directly determined through the source design, reducing the influence caused by problems in the engineering installation position; the structure is simple and the effect is practical.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figure 1 , the present utility model provides a water system exhaust device, including,

[0020] The exhaust pipe 1 is vertically arranged, and an exhaust assembly is provided at its top end, and a water inlet 11 and a water outlet 12 are respectively provided on its side and bottom;

[0021] The water inlet pipe 2 is horizontally arranged and connected to the water inlet 11; and,

[0022] The water outlet pipe 3 is vertically arranged and connected to the water outlet 12;

[0023] Among them, the inner diameter of the exhaust pipe 1 is more than 1.5 times the inner diameter of the water outlet pipe 3.

[0024] In the use of this application, it is welded to the water outlet pipeline of the unit water-side heat exchanger, placed vertically, the exhaust assembly is connected to the top outlet of the exhaust pipe 1, and the top outlet of the exhaust pipe 1 is the highest point of the unit, which is easier to remove the air in the system; this structure is directly welded inside the unit, greatly reducing the leakage risk; by directly determining the position of the exhaust assembly through the source design, the influence caused by the problem of the engineering installation position is reduced; the structure is simple and the effect is practical.

[0025] In one embodiment, please refer to Figure 2 , the exhaust assembly is an exhaust valve 4.

[0026] In one embodiment, the water inlet 11 is located in the middle and lower part of the side of the exhaust pipe 1.

[0027] It should be noted that if there are directional indications involved in the embodiments of the present utility model, such as up, down, left, right, front, back..., the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture as shown in the drawings. If the specific posture changes, the directional indications will also change accordingly.
