The invention relates to a fully fluorine lined self-operated micropressure regulation valve. The fully fluorine lined self-operated micropressure regulation valve comprises a valve body, a valve rod,a valve element, a sleeve, a valve deck, an execution mechanism, a spring, a spring seat and an adjusting screw. The lower half portion of the sleeve is pressed into the upper portion of the valve body. The upper half portion and the lower half portion of the sleeve are fixed through bolts. The upper half portion of the sleeve is connected with the lower half portion of the execution mechanism. The upper half portion of the execution mechanism is connected with the valve deck. A leather gasket is arranged between the upper half portion and the lower half portion of the execution mechanism. The leather basket is a beef tallow sealing leather gasket through which the upper half portion and the lower half portion of the execution mechanism are fixedly connected in a sealing mode. The valve body and the valve deck are provided with sealing layers. The sealing layers are closely attached to the outer surfaces of the valve body and the valve deck to form sandwich layers capable of accommodating gas or liquid. The fully fluorine lined self-operated micropressure regulation valve designed by the invention is a connecting structure for improving the airtightness, is simple in structure, good in using effect and timely in air leakage detection effect and facilitates timely maintenance.
Description
technical field [0001] The invention relates to the technical field of self-operated regulating valves, in particular to a fully fluorine-lined self-operated micro-pressure regulating valve. Background technique [0002] The self-operated regulating valve is a regulating valve that relies on the pressure and temperature of the medium flowing through the valve itself as the energy source to drive the valve to work automatically. However, the self-operated regulating valve tends to have insufficient adjustment sensitivity and poor sealing performance during long-term use, resulting in a low service life and poor use effect of the self-operated regulating valve. The air-tightness problem requires the use of a special air-tightness detection device , many operating procedures, time-consuming and labor-intensive. Contents of the invention [0003] In view of the deficiencies in the background technology, the present invention relates to a fully fluorine-lined self-operated mic...
