Abstract
A machinery soft starting valve comprises a valve, a connecting component (12) and screws (9), wherein the valve is connected with the connecting component (12), and the screws (9) with different inner diameters are arranged inside the valve and replaced at any time according to different pressures and flows. The machinery soft starting valve has the advantages that requirements for accurate control of opening time and closing time and generality can be met at the same time according to different pressures and flows; the mechanical soft starting valve has good sensitivity and a more accurate starting time control method, and simultaneously maximal unloading capacity of a valve body is ensured; the problem of blocking of a valve core is solved and the valve core can be better maintained and replaced; and generality of connection between flanges and threads is achieved.
Description
Technical field
The utility model relates to valve technology field, specifically a kind of mechanical soft starting valve.
Background technique
1, in the market soft starting valve is difficult to satisfy simultaneously accurate control and the versatility of opening and closing time under different pressures and flow; It adopts new valve body or sacrifice starting time or off-load ability to adapt to different pressures and range of flow.2, present soft starting valve adopts flange to connect or adopts and is threaded, and it generally can not be general.Maintenance and replacing difficulty when 3, general soft starting valve spool stops up.
Summary of the invention
The purpose of this utility model is a kind of nylon screw by changing different size of design with the mechanical soft starting valve of the versatility requirement that realizes valve body.
The utility model machinery soft starting valve, comprising: valve is connected with connection part 12.Use connection part 12 can realize that valve body is connected with flange; Do not use connection part 12 can realize that valve body is connected with internal thread.
Described valve comprises: valve gap 1, elastomer diaphragm 4 form with valve body 11 atmospheric pressure cavity that seals; Nut 2, intermediate plate 3, elastomer diaphragm 4, spring 5 form with valve rod 8 and move up and down mobile mangetic core assembly; Elastic packing back-up ring 6, sleeve block 7 form the caging system of mangetic core assembly; Valve rod 8 and rubber seal 10, valve body 11 form off-load and the closed system of valves; Valve rod 8 and screw 9 form the jet system of atmospheric pressure cavities.Described nut 2, intermediate plate 3, elastomer diaphragm 4, spring 5, elastic packing back-up ring 6, sleeve block 7, valve rod 8, screw 9, rubber seal 10 connects successively and is contained in the inner chamber that valve gap 1 is connected with valve body 11.
The different through-hole diameter screws 9 that will change at any time according to different pressures and flow.
The advantage of the utility model machinery soft starting valve is: 1, can satisfy simultaneously the accurate control of opening and closing time and the requirement of versatility under different pressures and flow; 2, have better sensitivity and more accurate starting time controlling method guaranteed simultaneously the maximum off-load ability of valve body; 3, the spool blockage problem can better be keeped in repair and change; 4, can realize flange and the versatility that is threaded and requires in connection.
