Energy-saving temperature control valve

Abstract

The invention provides an energy-saving temperature control valve which comprises a valve body, a temperature sensing probe, an actuator assembly, a guide tube, a thermal insulation frame and a piston. The thermal insulation frame is arranged above the valve body. The actuator assembly is connected to the thermal insulation frame. The temperature sensing probe is connected with the actuator assembly through the guide tube. The energy-saving temperature control valve is characterized in that a two-layer spring assembly is arranged inside the thermal insulation frame, and the two-layer spring assembly is composed of an upper portion right-handed spring and a lower-portion left-handed spring. Due to the fact that the springs are arranged to be of a two-layer combined structure, on the condition that the size of the valve is not enlarged, the spring force strength and durability of the springs can be improved, the spring adjusting performance is more flexible, the service life is prolonged, and normal production is effectively ensured; meanwhile, the springs are connected with the piston, the piston is directly controlled by the springs to move, then, a valve rod is driven to move, adjustment is more convenient, and the valve body is more flexibly turned on and turned off.

Description

technical field [0001] The invention belongs to the technical field of valves, in particular to a temperature control valve. Background technique [0002] The energy-saving temperature control valve is a valve that can automatically adjust the temperature without external energy. Pharmaceutical and other production engineering. The energy-saving temperature control valve realizes automatic adjustment through the principle of thermal expansion of the liquid in the temperature sensor and the incompressibility of the liquid, which overcomes the problems of unstable control accuracy and short life of other types of temperature control valves in high temperature and high humidity environments. The existing energy-saving temperature control valve generally installs a spring above the valve body, through which the valve stem moves up and down to realize the opening and closing of the valve body, but ordinary springs are prone to insufficient spring force and difficulty in position...

Problems solved by technology

The energy-saving temperature control valve realizes automatic adjustment through the principle of thermal expansion of the liquid in the temperature sensor and the incompressibility of the liquid, which overcomes the problems of unstable control accuracy and short life of other types of temperature control valves in high-temperature and high-humidity environments.

The existing energy-saving temperature control valve generally installs a spring above the valve body, through which the valve stem moves up and down to realize the opening and closing of the valve body, but ordinary springs are prone to insufficient spring force and difficulty in positioning the spring after long-term use The problem affects the normal use of the temperature control valve and severely limits industrial production
