Example Embodiment

[0040] The integrated flow temperature control device is directly connected with the main water pipe and the pouring bin branch pipe through the first and second live joints respectively, and the on-site assembly only needs to unscrew the live joints at both ends. Connect the power cord and data cable to the main controller. Power on the integrated flow temperature control device, and when the status light on the integrated flow temperature control device is always green, it indicates that the integrated flow temperature control device has been started, and the server software can be started for remote communication control.

[0041] The integrated flow temperature control device includes a waterproof, anti-heavy and anti-electromagnetic interference shell 8.

[0042] There is a two-way electric ball valve 1 in the shell, which controls the water flow according to control instructions; an internal digital temperature measuring device 2, which outputs the temperature of the water in...

Abstract

An integral flow and temperature control device comprises an electric ball valve, an interpolated digital temperature measuring device, a flow measuring device and an integral control circuit board which are fixedly integrated and packaged in a casing. Loose joints with diameter equal to that of external pipes are arranged at two ends of the integral flow and temperature control device, and accordingly the integral flow and temperature control device is flexible, convenient and fast in connection. The integral flow and temperature control device is subjected to data exchange with a main controller and supplied with power through a bus, can complete functions of temperature collection and flow PID(proportion, integration and differentiation) regulation and the like, can complete flow regulation once the main controller outputs a specific flow rate, has excellent stability in control (floating control/proportion control), guarantees stability and accuracy of cooling water flow, and further controls concentrate temperature and stress, and guarantees engineering quality and progress.

Description

technical field [0001] The invention relates to an integrated water flow and temperature control device, referred to as an integrated flow temperature control device, in particular to an integrated flow temperature control device for temperature collection, flow collection and control in large-volume concrete water heat exchange. Background technique [0002] The temperature stress of mass concrete in large-scale hydropower projects involves the risk of dam cracking, and its development process can be divided into three stages: (1) Early stress, starting from the pouring of concrete and ending when the heat release of cement basically ends, generally about one month or so. This stage has two characteristics: one is that a large amount of heat of hydration is emitted due to cement hydration, which causes a sharp change in the temperature field; the other is that the elastic modulus of concrete changes sharply with time; From the time when the exothermic effect is basically o...
