Description
Technical field
The utility model relates to a kind of solenoid valve, specifically refers to a kind of solenoid valve with manually-operable control.
Background technique
Solenoid valve be pneumatic or the system such as hydraulic pressure in common a kind of control valve, traditional solenoid valve is namely opened or closing motion afterwards automatically in energising.But in use, owing to circuit or electromagnetic coil etc. can break down unavoidably, thereby can cause solenoid valve to open normally or to close, and then it can not be worked as usual.In order to overcome defects, people have designed the manually solenoid valve of control of band at present, should be with the solenoid valve of manually controlling, usually at main valve body pilot valve is installed, and be provided with and can drive the manual lever that the main valve stem in the main valve body moves, in order to when installation, maintenance, is used as to debug, also can be under the state of emergency, with hand pressing operation bar, make solenoid valve open in time as required or close.
But the arranged direction of existing manual lever mostly and main valve stem not on same axis, operate very inconvenient.Even have operating stem and main valve stem to remain on solenoid valve on the same axis, but because of the defective on the linkage structure of operating stem and main valve stem, often after promoting operating stem, can't make main valve stem accurately mobile, and overall structure is compact not.
Therefore for existing manual solenoid valve, still need await further improvement.
Summary of the invention
Technical problem to be solved in the utility model is the present situation for prior art, provide a kind of rational in infrastructure, be convenient to the accurately manual solenoid valve of operation.
The utility model solves the problems of the technologies described above the technological scheme that adopts: a kind of manual solenoid valve, comprise main valve body, be positioned at the main valve stem of main valve body and can drive pilot valve and the operating stem that main valve stem moves, have a plurality of gas ports on the described main valve body, it is characterized in that: the end at described main valve body is fixed with module, have piston cavity and through hole with the same axis arranged of described main valve stem in this module, described operating stem one end stretches in the through hole and connects with an end face of the piston that is arranged in piston cavity, the other end of operating stem is exposed to described module and becomes holding end, the other end of described piston then connects with the end of described main valve stem, have simultaneously the groove of the valve rod insertion that supplies pilot valve in described module, have the air outlet that is communicated with source of the gas by first passage in the bottom of this groove, and on this module, also have the second channel of the rod chamber that is communicated with described groove and piston cavity.
As further improvement of the utility model, described module can have two, be separately fixed at the two end part of main valve body, accordingly, pilot valve and operating stem and piston also have two, at this moment, in turn action that can be by two pilot valves or promote arbitrary operating stem, just can make solenoid valve be in long-time unlatching or the state of closing for a long time in.Certainly, also can adopt a pilot valve and an operating stem, reset by spring.
In order to make overall structure more compact, reasonable, the suction port of described first passage is positioned at described module on the interior edge face of main valve body, simultaneously have first, second gas circuit that is connected with first passage on the respective modules at described main valve body, and this first, second gas circuit all is communicated with the pressure gas port in a plurality of gas ports on the described main valve body.By the pressure gas on the solenoid valve pressure gas port and the control of corresponding pilot valve, can promote main valve stem and move as required like this.
In above-mentioned each scheme, be preferably, described groove is positioned on the upper-end surface of described module, and namely pilot valve is positioned at the module top, and it is comparatively convenient to install.
Compared with prior art, because operating stem of the present utility model and the coaxial distribution of main valve stem, and pilot valve and operating stem all promote main valve plug by piston, can make valve rod accurately mobile, while is because pilot valve and operating stem share a module, thereby compact overall structure, reasonable, takes up room little, cost is low, and also has advantages of convenient operation.
