A preset dynamic differential pressure balance temperature control valve

Abstract

A prefabricated dynamic differential pressure balance temperature control valve, which is used together with a temperature control head including a temperature envelope bellows. The valve body is built with a valve core body connected to the upper end of the valve body; the valve core body is built with a valve stem , a scale adjustment cap, a spring, a piston flow regulator and a rubber gasket; the scale adjustment cap is connected to the upper end of the valve core body, and the valve stem passes through the spring, the piston flow regulator and the rubber gasket in turn, the valve stem, The piston flow regulator and the rubber gasket constitute a moving body that moves vertically in the valve core; one end of the spring touches the scale adjustment cap upwards, and the other end touches the moving body, and the moving body moves according to the pressure of the fluid. And the change of temperature acts in the vertical direction, and changes the deformation of the spring, so as to control the flow of the fluid to be stable.

Description

technical field [0001] The invention relates to the field of temperature control valves, in particular to a preset dynamic differential pressure balance temperature control valve, which solves the problem of uneven heating and cooling of room temperature existing in the existing heating system, and can accurately adjust the pressure drop and flow rate at the same time. To improve the liquid flow state in the pipe network system, achieve the liquid balance of the pipe network, reduce the noise of the pipe network and save energy. Background technique [0002] Temperature control valve is a typical application of flow regulating valve in the field of temperature control. Its basic principle is to control the outlet temperature of the equipment by controlling the inlet flow of heat exchangers, air conditioning units or other heat and cold equipment, and the primary heat (cold) medium. . When the load changes, the flow is adjusted by changing the opening degree of the valve to ...

AI Technical Summary

Problems solved by technology

This type of temperature control valve cannot automatically eliminate the hydraulic imbalance caused by various factors in the water system, cannot maintain the flow required by the user, cannot use the pressure difference to adjust the opening of the valve, and cannot use the pressure drop change of the valve core to compensate The change of pipeline resistance, the noise generated by the long-term impact on the pipeline and the valve body will cause noise pollution, and the more dangerous is the fatigue damage of the pipeline and valve body caused by the long-term impact, which will reduce the service life
