Labeled as: the water supply system comprises a water pipe 101, a water supply pipe II 201, a valve II 202, a water supply pipe I203, a middle pipe body 204, a right-angle elbow 205, a connecting pipe I206, a connecting pipe II 207, a valve I208, a flange interface I209, a flange interface II 210, a tower body 211 and an eccentric reducing joint 212.

Detailed Description

As shown in the figure, the special inlet tube for the cross-flow cooling tower comprises a tee reducing eccentric inlet tube arranged in the middle of the lower end of a tower body 211, the tee reducing eccentric inlet tube is not arranged outside the tower body 211, a pipeline can be prevented from being exposed, the attractiveness is improved, and meanwhile the installation of a cooling tower shell is facilitated.

The eccentric inlet tube of tee bend reducing includes well body 204, and well body 204 transversely puts at tower body 211 lower extreme position placed in the middle, has flange interface 209 at well body 204 downside through-connection, all connects 212 and quarter bend 205 through-connection through eccentric reducing at well body 204 both ends, and quarter bend 205 is connected with flange interface two 210. The first flange interface 209 opens downward and the second flange interface 210 opens upward.

The first flange connector 209 is arranged at the lower end of the tower body 211, and a pipeline outside the tower body 211 is split, so that the transportation is facilitated and the installation is carried out on site. Specifically, the first flange interface 209 is connected with a first water supply pipe 203, the first water supply pipe 203 is connected with a second water supply pipe 201 in a penetrating manner, and the first water supply pipe 203 is provided with a second valve 202.

The second flange interface 210 is sequentially connected with a first connecting pipe 206, a first valve 208 and a second connecting pipe 207, and the second connecting pipe 207 is connected with a water inlet in the tower top. The first connecting pipe 206, the first valve 208 and the second connecting pipe 207 which are respectively connected with the second two flange interfaces 210 are symmetrically distributed by taking the symmetry line of the tower body 211 as the symmetry line. The first connecting pipe 206, the first valve 208 and the second connecting pipe 207 which are symmetrically arranged can enable the pressure difference of water entering the middle pipe body 204 from the first flange interface 209 to be smaller when the water enters the water inlet at the top of the tower.

As shown in fig. 4, the rotation axis of the middle pipe 204 is parallel to the plane where the rotation axes of the two flange connectors 210 are located, and there is no intersection point with the plane, so that the two flange connectors 210 can deviate from the tank body of the cooling tower, and under the condition that the central axis of the quarter bend 205 is not fixed, the central axis of the middle pipe 204 can deviate towards the inside of the tower by using the eccentric reducing joint 212, so that the flange connector 209 can deviate towards the inside of the tower, and a space is left between the flange connector 209 and the bottom edge of the tower, which is convenient for installation and maintenance.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
