Abstract
The utility model relates to a multi-function normal close two-position two-way solenoid valve, utilizing a manual cam mechanism, and the mechanism can push up a valve core to make the normal close solenoid valve become a normal open pipeline and can also not push up the valve core to make the valve become a general normal close two-position two-way solenoid valve. The valve has the advantages that when the pipeline needs to be opened to work for a long time, the valve can be opened by a manual cam so as to save electrical energy and extend the service life of a solenoid coil, and when the valve can not be opened due to the failure of the solenoid coil and the pipeline is not allowed to be closed immediately, the valve can also be opened to work by the manual cam in time. The valve is suitable for the general pipeline with liquid or gas medium.
Description
The utility model relates to a kind of multi-functional Normally closed type two-position two-way solenoid valve that uses liquid or gas medium.
With regard to general Normally closed type two-position two-way solenoid valve commonly used, mainly formed by electromagnetic coil, spool, spring, valve body and seal ring.Normally closed type two-position two-way solenoid valve in " pneumatic element product sample " that Chinese China Machine Press publishes all belongs to this class formation.This solenoid valve is not the valve closes state during galvanization, is valve opening state during turn-on current.The deficiency of this structure is, when needs long period during continuous Open valve, electromagnetic coil just must be switched on for a long time continuously, and power consumption is bigger, and electromagnetic coil easily causes the too high or scaling loss of heating.Another deficiency of this structure is in a single day malfunctioning when solenoid valve, and when not opening valve port, and the pipeline at place need to be eager Open valve work, must change or removes this solenoid valve, thereby influence the proper functioning of this solenoid valve place pipeline.
The purpose of this utility model be to avoid above-mentioned deficiency of the prior art and provide a kind of can be under without the situation of power supply long-time Open valve or when solenoid valve is in a single day malfunctioning, the multi-functional Normally closed type two-position two-way solenoid valve that also can often go into operation and do.
The purpose of this utility model can reach by following description: a kind of multi-functional Normally closed type two-position two-way solenoid valve, formed by electromagnetic coil (1), electromagnetic valve core (2), spring (3), electromagnetic valve body (4), sealing volume (8), it is characterized in that: in the described valve body (4), cam mechanism (5) is installed, this cam mechanism (5) can make this valve become the normal opened type pipeline spool (2) jack-up, also can not back down spool (2), make this valve become common Normally closed type two-position two-way solenoid valve.
The purpose of this utility model can also reach by following description: described cam mechanism (5) can be installed for the manual handle (6) of control, and this handle (6) can drive cam mechanism (5) jack-up or jack-up spool (2) not.
Handle in the utility model (6) and cam mechanism (5) can carry out axially locating with plate washer (7), cam mechanism (5) can be rotated and can not move axially.
The drawing of accompanying drawing is described as follows:
1, electromagnetic coil; 2, electromagnetic valve core; 3, spring; 4, electromagnetic valve body; 5, cam mechanism; 6, handle; 7, baffle plate; 8, seal ring.
The utility model is described in further detail below in conjunction with (accompanying drawing) embodiment: a kind of multi-functional Normally closed type two-position two-way solenoid valve of describing in the accompanying drawing, formed by electromagnetic coil (1), electromagnetic valve core (2), spring (3), electromagnetic valve body (4) and seal ring (8), the cam mechanism (5) of band handle (6) is installed on electromagnetic valve body (4), this cam mechanism (5) carries out axially locating with O RunddichtringO and electromagnetic valve body (4) bore seal with the baffle plate (7) of being with screw.This cam mechanism (5) drives with handle (6), can in valve body (4), rotate, when turning to certain orientation, can be with spool (2) jack-up, when turning to other direction again, spool (2) can be put down, by the effect of spring (3) power and the sealing valve port on the valve body (4) and become common Normally closed type two-position two-way solenoid valve.The normal open of this valve such as need long period, can be with spool (2) jack-up, and the power supply of cut-out electromagnetic coil, thereby save electric energy, increase the life-span of solenoid valve, simultaneously, when this valve in use, electromagnetic coil (1) was in case lost efficacy, when needing the work of pipeline normal open again, then available handle (6) drives cam mechanism (5) and opens spool (2) and makes the pipeline normal open, does not then need to change solenoid valve and the proper functioning that influences pipeline.
The utility model has following advantage compared to existing technology:
1, Multi-function normal close two-position two-way solenoid needs the long period during normal open, and available cam mechanism (5) is spool (2) jack-up, and saves energy increases life-span of solenoid (1).
2, this valve in use, in a single day malfunctioning such as solenoid (1), can not produce magnetic field mentions spool (2) to open valve, this moment, pipeline did not allow again in time to quit work or not have spare part replaceable, then the cam mechanism (5) of available band handle (6) backs down spool (2), and makes the unimpeded normal operation of pipeline.
Claims (3)
1, a kind of multi-functional Normally closed type two-position two-way solenoid valve, formed by electromagnetic coil (1), electromagnetic valve core (2), spring (3), electromagnetic valve body (4) and seal ring (8), it is characterized in that: in the described valve body (3), being equipped with can be with the cam mechanism (5) of spool (2) jack-up.
2,, it is characterized in that on cam mechanism (5), being equipped with the handle of controlling for manually (6) by the described multi-functional Normally closed type two-position two-way solenoid valve of claim 1.
3, by claim 1 or 2 described multi-functional Normally closed type two-position two-way solenoid valves, it is characterized in that cam mechanism (5) carries out axially locating with baffle plate (7).
