Abstract
The utility model relates to a pneumatic electromagnetic valve. The pneumatic electromagnetic valve comprises a socket, a coil, a front cover, a valve body and a rear cover, wherein the socket, the coil, the front cover, the valve body and the rear cover are sequentially connected. The rear cove comprises a cover body, a rear cover piston and a breathing opening, a slot corresponding to the breathing opening is formed in the cover body, and a filter is connected to the interior of the slot in an inserted mode. The pneumatic electromagnetic valve effectively prevents outside impurities from entering the valve body, reduces fault rate, is long in service life and improves benefits of enterprises.
Description
Technical field
The utility model relates to a kind of solenoid valve, relates in particular to a kind of air-operated solenoid valve that filter sheet is arranged.
Background technique
Along with the importing of modern mechanical production, air-operated solenoid valve is a kind of electromechanical integrated product that is widely used in control field, and it substantially can be divided into the assembling of electromagnetic valve coil section and valve body two-part and consist of; Wherein, the device that is electrically connected to electromagnetic valve coil is divided into two independent sectors, first portion is the socket of mechanical structure, second portion is the control circuit board as drive circuit, drive circuit is accepted outside control signal rear driving electromagnetic valve coil work, socket is serially connected with between electromagnetic valve coil and control circuit board by the flexible cord road, as the connection interface between electromagnetic valve coil and drive circuit.In addition, valve body can be divided into again protecgulum, valve body and bonnet and is connected a part and connects successively.
In use, can run into woodworking machinery, stone machining equipment etc. industry unavoidably, the environment at place is poor, dust is many, and air-operated solenoid valve in use can enter valve inner at foreign matters such as a large amount of dust of pneumostome position inspiration, wood chips, is stuck in the seal ring position, cause leakage, cut seal ring when serious, cause the large leakage of air-operated solenoid valve and lost efficacy, service time the short performance of enterprises that affects.
The model utility content
The purpose of this utility model is to provide a kind of air-operated solenoid valve, in mechanism of the inner increase of bonnet, a filter sheet is installed, to solve the technical problem of prior art.
For achieving the above object, the utility model provides a kind of air-operated solenoid valve, comprise socket, coil, protecgulum, valve body and bonnet, described socket, coil, protecgulum, valve body are connected with bonnet and are connected, described bonnet comprises lid, bonnet piston and pneumostome, be provided with a slot on the lid of the described pneumostome of correspondence, the filter sheet of pegging graft in described slot.
According to the described air-operated solenoid valve of the utility model preferred embodiment, described filter sheet is the mesh grid of multilayer stainless steel.
According to the described air-operated solenoid valve of the utility model preferred embodiment, described filter sheet is the pore plastic board.
The utility model compared with prior art the utlity model has following advantage:
1, prevent that effectively the impurity such as extraneous water, oil, dust, wood chip from entering in valve body, greatly reduces the operational failure of solenoid valve;
2, long service life improves the performance of enterprises.
Description of drawings
Fig. 1 is the connection diagram of the utility model air-operated solenoid valve;
Fig. 2 is the schematic internal view of the utility model bonnet.
Embodiment
Below in conjunction with accompanying drawing, illustrate the utility model.
See also Fig. 1, air-operated solenoid valve comprises socket 10, coil 20, protecgulum 30, valve body 40 and bonnet 50, described socket 10, coil 20, protecgulum 30, valve body 40 are connected with bonnet sequentially and are connected, at first power control signal line 60 enters socket 10, socket 10 is by flexible cord road serial connection coil 20, control the motion of piston in protecgulum 30 by the break-make of control coil 20, and then affect the movement of valve rod in valve body 40, open or close different vents.
see also Fig. 2, wherein, bonnet 50 comprises again lid 51, bonnet piston 52 and pneumostome 53, be provided with a slot 54 on the lid 51 of the described pneumostome 53 of correspondence, grafting one filter sheet 55 in described slot 54, when the valve rod in valve body 40 moves to bonnet, valve rod compressing bonnet piston 52, in the confined space that bonnet piston 52 coats, be full of pressurized gas and waited expansion, when switching command is assigned, valve rod stops oppressing bonnet piston 52, 52 li instinct pressurized gass of bonnet piston begin to expand and push valve rod to other direction, between 52 1 contractings one of bonnet piston are risen, gas volume in lid 51 is also carrying out the contracting of rising, turnover lids 51 after one air-flow that rises by a contracting formation filters by filter sheet 55, water in ambient air, oil, dust, the impurity such as wood chip all are blocked in the outside and can enter.
In addition, the material of making filter sheet 55 can be the mesh grid of multilayer stainless steel or pore plastic board, as long as it is just passable to breathe the material that smooth and easy prevention impurity enters.
The utility model compared with prior art the utlity model has following advantage:
1, prevent that effectively the impurity such as extraneous water, oil, dust, wood chip from entering in valve body, greatly reduces the operational failure of solenoid valve;
2, long service life improves the performance of enterprises.
Above disclosed be only several specific embodiment of the present utility model, but the utility model is not limited thereto, the changes that any person skilled in the art can think of all should drop in protection domain of the present utility model.
