Balance pump for heat supply

Abstract

A balance pump for heat supply comprises a receiving tube, a mixing tube, and a jet flange and a jet nozzle which are coaxially arranged, wherein the mixing tube is an integral body formed by sequentially connecting a drainage taper pipe, a throat pipe and a diffuser pipe end to end, the jet flange is installed at the front end of the jet nozzle and communicates with a central through hole of thejet flange, the tail end of the jet nozzle is stretched into the drainage taper pipe and suspended in the drainage taper pipe, the front end of a pipe body of the receiving pipe is fixed on the jet flange, the tail end of the pipe body of the receiving pipe is fixed on the outer side wall of the throat pipe, the jet nozzle is placed in the receiving pipe, a jet guiding inlet is formed in a position, corresponding to the throat pipe, on the side wall of the throat pipe, and connected with the jet guiding pipe in communication mode, a plurality of drainage channels are symmetrically formed in the periphery of the central through hole in the jet flange, a regulation water inlet is formed in the side wall of the tail segment of the diffuser pipe, a regulation water outlet communicates with theregulation water inlet through a regulation pipe, and bolts are arranged on the drainage channels in threaded connection mode, and block the drainage channels or regulate the size of the regulation water outlet. The balance pump for the heat supply can solve the problems that an existing balance valve or regulating valve is large in debugging difficulty, limited in installation and single in function, a water mixing device is long and the like.

Description

technical field [0001] The invention belongs to the field of heating equipment, in particular to a balance pump for heating. Background technique [0002] Traditional heating systems usually use balance valves or control valves to adjust hydraulic balance. However, due to the coupling and complexity of the heating system itself, balance valves or control valves need to be designed and debugged according to factors such as water volume and pressure difference, which is difficult to design and debug. Large, and the use effect is not ideal. [0003] For the utility model whose patent application number is CN201520004468.8 and named "a water mixing device for heating system", the equipment length is long, the installation conditions are limited, and the equipment functions are single, without adjustment and cleaning. dirty function. Contents of the invention [0004] In order to overcome the defects and deficiencies of the above-mentioned technologies, the present invention ...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the defects and deficiencies of the above-mentioned technologies, the present invention provides a balance pump for heating, which solves the problems that the adjustment of the balance valve or regulating valve in the existing heating system is difficult, and the effect of improving hydraulic imbalance is not obvious, and at the same time solves the problems of the existing mixing pump. The length of the water device is too long, the installation is limited, and the function is single, etc.
