Water distribution and collection device

Abstract

The invention provides a water distribution and collection device which comprises a water distributor, a water collector and a supporting structure, wherein a water-collection main pipe of the water collector is provided with a plurality of water-collection joints and flow regulating valves which are in one-to-one correspondence with the water collection joints; the flow regulating valves comprise regulating valve cores and regulating caps above the regulating valve cores; the regulating valve cores comprise valve core screw caps fixedly arranged on the water-collection main pipe and regulating bases fixedly arranged above the valve core screw caps; the outer walls of the regulating bases are provided with external thread parts spacing bosses which has certain distance with the upper parts of the external thread parts; the inner walls of the regulating caps are provided with internal thread parts and spacing clamping platforms above the internal thread parts; the regulating caps are upward rotated until the internal thread parts are separated from the external thread parts, the spacing clamp platforms can not continuously move upward as being clamped by the spacing bosses, so that the internal thread parts of the regulating caps can rotate freely at smooth intervals between the external thread parts and spacing bosses of the regulating bases, so that the condition that the regulating caps and the regulating bases are locked can be prevented, the reliability of the water distribution and collection device is improved, and the operation comfort of a user is enhanced.

Description

technical field [0001] The invention relates to a water diversion device, which belongs to the technical field of heating and ventilation equipment. Background technique [0002] The sub-catchment refers to the device used to connect the heating main water supply pipe and return pipe in the geothermal heating system. The sub-catchment includes two parts: the sub-catchment and the water collector. The water separator is a water distribution device used to connect the water supply pipes of various heating pipes in the water system. The water collector is a water collection device used to connect the return pipes of various heating pipes in the water system. A plurality of water flow branches are connected between the water separator and the water collector to realize water circulation. [0003] At present, the commonly used sub-collectors include brackets, water-distributing main pipes and water-collecting main pipes fixedly installed on the brackets. The water-distributing...

Problems solved by technology

[0009] For this reason, the technical problem to be solved by the present invention is to overcome the low operating comfort of the flow regulating valve on the water collector in the sub-catchment in the prior art and the user is prone to misuse, which leads to looseness inside the regulating valve spool. Seriously affect the working reliability of the water collector and reduce the service life of the valve core, so as to provide a water manifold with a flow regulating valve with high operating comfort and which can prevent the user from misoperating and causing looseness inside the valve core
