Intelligent sleeve type high temperature high voltage solenoid valve

Abstract

The invention relates to an intelligent sleeve type high-temperature high-pressure magnetic valve, comprising a magnet head, a shielding sleeve and a valve body. A magnet coil and a dynamic iron core are installed in the magnet head, a radiating fin is arranged on the outer portion of the shielding sleeve, a dielectric inlet end and a dielectric outlet end are arranged on the lower portion of thevalve body, and a center dielectric passage is arranged between the inlet end and the outlet end. A valve base cylinder is installed in the valve body, a thread guide body is arranged on the upper end of the valve base cylinder, the bottom of the valve base cylinder is embedded on the valve body, and the lower portion of the valve base cylinder is provided with a valve base center hole which is connected with the center dielectric passage. A flap is mounted in the valve base cylinder, an assistant valve hole is arranged on the lower portion of the flap, the upper end and the lower end of a valve rod are respectively connected with an assistant valve, and a return spring is arranged on the valve rod. The invention has smart and reasonable design. The invention which adopts a kick rigidity micro-resilient seal pair structure can permanently work under the working conditions that the temperature is smaller or equal to 350 DEG C, and the pressure is 0-17.5 MPa, which guarantees the non-leakage and reliable working of the valve, and the valve also can operate reliably without leaking, particularly under the severe conditions of small pressure difference and temperature difference alternation.

Description

technical field [0001] The invention relates to a solenoid valve, in particular to an intelligent sleeve-type high-temperature and high-pressure solenoid valve for high-temperature and high-pressure fluid. Background technique [0002] The solenoid valve is one of the important components of the automatic control system in the industrial production process. Especially when only two-position control is required in the process flow, the selection of a solenoid valve with a suitable flow capacity, in line with the production conditions and environmental requirements, and with an equivalent caliber can not only adapt to production. Demand can save investment and daily maintenance costs. Therefore, to ensure a good control effect in the production process, there are usually strict and specific requirements for the relevant parameters of the solenoid valve, such as leakage, flow capacity, reliability, etc., especially for solenoid valves that flow through high-temperature and high...
