Example Embodiment

[0021] (Example 1)

[0022] Referring to Fig. 1, this embodiment is a dual-purpose solenoid valve that can be opened manually or electrically. It has a valve body 1, a valve cavity 2 surrounded by the valve body 1, an inlet channel 11 and an outlet channel 12. , the valve seat 3, the valve core 4, the spring 5, the moving iron core 6, the winding 7, the static iron core 8, and the push rod 9 arranged in the valve cavity 2; the valve cavity 2, the inlet passage 11 and the outlet passage 12 are communicated, The spring 5 is located between the valve core 4 and the static iron core 8 and is sleeved on the push rod 9, and the winding 7 is arranged around the static iron core 8; one end of the push rod 9 protrudes The valve cavity 2 is exposed outside the valve cavity 2 , and the other end of the push rod 9 extends into the valve cavity 2 and is fixedly connected with the moving iron core 6 .

[0023] The number of the windings 7 is one, and it is arranged in the valve cavity 2 ar...

Example Embodiment

[0029] (Example 2)

[0030] Referring to FIG. 2 , this embodiment is basically the same as Embodiment 1, the difference is that the dual-purpose solenoid valve of this embodiment has two windings 7 arranged in the valve cavity 2 around the static iron core 8 , which are outer windings respectively. 71 and inner winding 72. The two windings can be connected to the lower voltage power supply and the higher voltage power supply respectively, so that under the action of the higher voltage power supply, one of the windings can provide a larger adsorption force to realize automatic electric start. If it is turned on, the other winding can also provide a smaller adsorption force under the action of a lower voltage power supply after turning on, so as to maintain the normally-on state. The winding 7 in this embodiment is connected to the external power supply through four wires 200 .

[0031] Compared with the dual-purpose solenoid valve in Embodiment 1, the dual-purpose solenoid va...

Example Embodiment

[0032] (Example 3)

[0033] Referring to FIG. 3 , this embodiment is basically the same as Embodiment 2, the difference is that a micro switch 16 is also fixedly arranged on the valve body 1 of this embodiment, and the part of the push rod 9 exposed outside the valve cavity 2 A trigger part 91 is fixedly arranged on the upper part, and the trigger part 91 can move with the movement of the push rod 3 and cause the micro switch 16 to be triggered.

[0034] When the dual-purpose solenoid valve of this embodiment is in use, the micro switch 16 and the winding 7 can be electrically connected, that is, the micro switch 16 is used to control whether the winding 7 is energized, so as to ensure that when the push rod 9 is pressed, the The trigger part 91 is driven to trigger the micro switch 16, so that the winding 7 is energized at the same time, so as to generate an adsorption force to maintain the conduction state of the dual-purpose solenoid valve of this embodiment.

Abstract

A solenoid valve with manual operation unit consists of valve body, valve cavity, inlet channel, outlet channel, valve base, spool, spring, active iron core, winding, static iron core and push bar. It is featured as setting said spring between spool and static iron core and jacketing said spring on push bar, arranging said winding around static iron core, exposing one end of push bar to be at outside of valve cavity and firm-jointing another end of push bar to active iron core.

Description

technical field [0001] The invention relates to an electromagnetic valve, in particular to a dual-purpose electromagnetic valve capable of manual operation. Background technique [0002] Chinese patent CN2355189Y discloses a dual-purpose solenoid valve with a flashlight, which is used to control the on-off of the fluid delivery pipeline. There are two channels in the valve cavity at the liquid port, and a manual valve core is installed between the two channels. Among the two valve cores, one channel communicates with the liquid outlet through the manual valve core, and the other channel passes through the manual valve core and then passes through the liquid outlet. The solenoid valve core communicates with the liquid outlet. There is a guide hole on the manual spool, and through the guide hole, the on-off state of the two channels is manually controlled to control the path of the liquid through the channel, so as to achieve the purpose of dual-use of hand and electricity. I...
