Embodiment Construction

[0012] see figure 1 , the water mixing pipeline 6 is connected between the return water tee 8 bypass and the water supply tee bypass, the water supply tee is a three-way mixing tank 3, and the pipeline at the water supply inlet of the three-way mixing tank Connect to the first pneumatic regulating valve 2; connect to the second pneumatic regulating valve 5 on the water mixing line; see figure 2 , the pneumatic regulating valve includes a valve 23, a pneumatic actuator 22 and a valve positioner 21. The valve is a split welded unequal diameter valve, and its valve body 231 is composed of two split parts and then welded. Yes, the two splits mean that they are cut into two symmetrical parts along the axial direction of the valve body (the axial direction of the inlet and outlet of the valve), and each split body is formed by die-casting; the outlet diameter of the valve is the diameter of the inlet 1.1-1.5 times, that is, the inlet of the valve is smaller than the outlet of the ...

Abstract

The invention provides an intelligent high-efficient directly-mixing heat exchanging unit, which aims at solving the problem for improving the heat efficiency of a heat supply system. The intelligent high-efficient directly-mixing heat exchanging unit is characterized in that a first pneumatic adjusting valve is connected onto a pipeline of a water supply inlet of a three-way water mixing tank; a second pneumatic adjusting valve is connected onto a water mixing pipeline; the pneumatic adjusting valve comprises a valve, a pneumatic actuator and a valve locator, the valve is a split welding irregular valve, a valve body is formed by combining and welding two split bodies, the two split bodies are two symmetric parts, which are split along the axial direction of the valve body, and each split body is molded in a die-casting manner; the diameter of an outlet of the valve is 1.1 to 1.5 times of that of the inlet. The intelligent high-efficient directly-mixing heat exchanging unit has the beneficial effects that the temperature is adjusted faster and more accurately; the balance of the heat and the hydraulic power of the heating system can be favored, and the heat supply quality of the system can be guaranteed.

Description

technical field [0001] The invention relates to an intelligent high-efficiency direct-mix heat exchange unit, in particular to an intelligent high-efficiency direct-mix heat exchange unit in a heating system. Background technique [0002] In order to meet the needs of various radiators using water supply and return water at different temperatures, and to save heat energy to the greatest extent on the premise of ensuring normal heating, CN201177315Y discloses a direct-connected heating system for high and low areas, high and low temperature mixed water heating, which The main point is to separate a mixed water pipeline through the return water tee on the return water pipeline directly connected to the heating system. The mixed water pipeline connects part of the return water to the bypass of the water supply tee of the water supply pipeline through the regulating valve, and controls the regulating valve. The opening degree, mix part of the return water into the supply water. ...
