Multi-path flow and temperature control valve with bypass port

Abstract

The invention discloses a multi-path flow and temperature control valve with a bypass port. The multi-path flow and temperature control valve comprises a control valve body, a water supply channel, ahot water channel, a hot water bypass way, a cold water bypass way and a cold water channel. A valve hand wheel is arranged at the upper end of the control valve body and rotationally connected with the control valve body. The front end of the upper surface of the control valve body is provided with an aperture ruler. A rotation valve element and a baffle are arranged in the control valve body. The rotation valve element is fixedly connected with the valve hand wheel and rotationally connected with the control valve body. The baffle and the control valve body are fixedly connected. The water supply channel, the hot water channel, the hot water bypass way, the cold water bypass way and the cold water channel are sequentially fixedly connected to the position right in front of the control valve body and the right front position, the right rear position, the left rear position and the left front position of the control valve body. According to the multi-path flow and temperature control valve, the cold loop and hot loop mixing proportion can be controlled, and meanwhile the respective bypass proportion of a cold loop and a hot loop can be controlled. The pipeline design is simplified,and meanwhile the valve control precision and the system running reliability are improved.

Description

technical field [0001] The invention relates to the field of temperature control, in particular to a multi-channel flow and temperature control valve with a bypass port. Background technique [0002] When the equipment needs the temperature control equipment to provide a circulating liquid with stable temperature and flow rate, but when the temperature control equipment is used to change the set temperature, the heating and cooling time is longer, the response is not fast enough, and it cannot meet the requirements of some new processes, and the use of two-way The circulating liquid of different temperature is switched, and the reaction is faster, but the temperature cannot be changed steplessly. If stepless change is required, the main process equipment needs to be equipped with additional heaters for control. Contents of the invention [0003] The purpose of the present invention is to provide a multi-channel flow and temperature control valve with a bypass port. By sett...
