Description

Collector Quick Connect

technical field

The utility model relates to a connecting piece, in particular to a quick connecting piece used for connecting solar heat collectors.

Background technique

At present, the engineering installation of solar energy products is relatively complicated, especially the large-scale split solar flat panel collector project, which involves series and parallel connections between multiple collectors during on-site construction and installation, and the inlet and outlet of the flat panel collectors are both Copper light tube, when multiple collectors are connected in series, two light tubes of equal outer diameter need to be connected. The current practice is as follows:

Traditional connection method 1: Connect the brass joints to the two light pipes respectively, and then connect the bellows in the middle. As shown in Figure 1, the end of the light pipe 12 of the heat collector 11 has a G1/2 outer wire through a brass joint 13, and the bellows 14 with G1/2 inner wires at both ends are connected in the middle by using the outer wire. This method makes the pipeline connection complicated, the installation efficiency is low, and a sufficient installation distance must be maintained between adjacent heat collectors, and the space utilization rate of the heat collectors connected in series is low.

Traditional connection method 2: Use a copper tube with a larger outer diameter to cover two bare tubes for gas welding. As shown in FIG. 2 , the copper pipe sleeve 23 is set on the light pipe 22 of the adjacent heat collector 21 , and the junction is sealed and welded by gas welding. This method is easy to burn out the sealing ring at the root of the light tube of the heat collector, resulting in water leakage of the heat collector, resulting in hidden dangers in quality, and at the same time, it is extremely inconvenient to weld on site and the installation efficiency is low.

Utility model content

In view of the above problems, the utility model provides a new type of quick connector, which is used for the connection between the series and parallel light tubes of the heat collector, without the need for on-site welding, and has the characteristics of quickness, convenience and high construction quality.

The purpose of this utility model is to realize through the following technical solutions:

The utility model relates to a quick connection piece of a heat collector, and the two ends of the corrugated pipe are connected with ferrule-type pipe joints.

In particular, the two ends of the bellows are connected to the ferrule-type pipe joint by welding.

The ferrule-type pipe joint includes a bellows welded joint, a snap ring and a nut. The snap ring is a copper ring with a thick middle and thin sides, and is installed inside the nut and the bellows welded joint. The bellows welded joint and the nut are in the The inner surface in contact with the snap ring has a ring structure with tapering diameter, which can make the two ends of the snap ring shrink radially when screwing in.

Preferably, the clasp is made of copper.

Preferably, the bellows welded joints and nuts are made of dezincification-resistant brass or stainless steel.

The heat collector quick connector described in the utility model, when installed on site, continuously tightens the nut of the ferrule-type pipe joint and the welded joint of the bellows, so that the edge of the clasp is continuously shrunk, forming a fixation and connection to the copper light pipe. Sealing; the bellows in the middle can be stretched, even if the centerlines of the two copper light tubes of the series collector are not on the same horizontal line, it can also play a buffer role, so as not to cause damage to the connecting parts, the connection is convenient and quick, and the series collection is greatly improved The installation efficiency of the heat collector is high, and the installation distance between the heat collectors is required to be small, which can improve the space utilization rate and the aesthetics.

Detailed ways

As shown in FIG. 3 to FIG. 4 , a structural diagram of a specific embodiment of the heat collector quick connector of the present invention is given. The connector is composed of a nut 31, a snap ring 32, a bellows welded joint 33 and a bellows 34, wherein the nut 31, the snap ring 32, and the bellows welded joint 33 form a ferrule-type pipe joint, which are connected to the two ends of the bellows 34 respectively. The welded connection is formed by a circumferential weld 35 .

The snap ring 32 is a red copper ring with a thick middle and thin sides. As shown in the figure, it has a snap ring diameter reduction section 36, which is installed inside the nut 31 and the bellows welding joint 33; the bellows welding joint 33 and the nut 31 are in contact with the snap ring The inner surface contacted by the ring 32 is an annular structure with a tapered diameter, and has a diameter-reducing section 37 and a diameter-reducing section 38 respectively; the welded joint 33 and the nut 31 of the bellows can be made of dezincification-resistant brass or stainless steel, and can be rotated When advancing, make the two ends of the snap ring 32 form a radial contraction.

During installation, the snap ring 32 is set on the corresponding heat collector light tube, and as the nut 31 and the bellows welded joint 33 are continuously tightened, the edge of the snap ring 32 can be continuously shrunk, and finally the copper light tube is fixed and fixed. Sealing; the bellows 34 in the middle can be stretched, even if the center lines of the two copper light tubes of the series collector are not on the same horizontal line, it can also play a buffer role, so as not to cause damage to the connecting parts, the connection is convenient and fast, and the series connection is greatly improved.
