Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention will be further explained with reference to the specific drawings. It is noted that the terms "first," "second," "third," "fourth," and the like (if any) in the description and in the claims of the present invention are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that the embodiments described herein may be practiced otherwise than as specifically illustrated or described herein. Furthermore, the terms "comprises" or "comprising," and any variations thereof, are intended to cover non-exclusive inclusions, such that a product or apparatus that comprises a list of elements or units is not necessarily limited to those elements or units expressly listed, but may include other elements or units not expressly listed or inherent to such product or apparatus.

Referring to fig. 1, a reinforced anti-leakage electromagnetic valve structure with a handle comprises a handle module, a main valve core module 200, a left electromagnet module 301 and a right electromagnet module 302, wherein the handle module is connected with the main valve core module 200 through the right side surface of the handle module to the right, and is connected with the left electromagnet module 301 through the left side surface of the handle module to the left, and the main valve core module 200 is connected with the right electromagnet module 302 to the right; the left side and the right side of the handle module are respectively provided with an annular recess, the annular recess is positioned on the outer ring of the opening of the inner cavity of the handle module on the left side and the right side of the handle module, and a first sealing ring 401 is arranged in any annular recess.

In some embodiments, the handle module comprises a handle shell 101, a head 102 and a shaft 103, wherein the head 103 is arranged at one end of the shaft 103, the other end of the shaft 103 penetrates into the handle shell 101 and is connected with a push rod 104 positioned in an inner cavity of the handle shell, one end of the push rod 104 is connected with a left electromagnet module 301, and the other end of the push rod is connected with a main valve core module 200; a second sealing ring 402 is arranged at the joint of the shaft 103 and the handle shell 101.

In some embodiments, the handle housing 101 is provided with a shaft hole, the circumference of the shaft hole is provided with a ring-shaped groove, and the second sealing ring 402 is clamped in the ring-shaped groove. In order to cooperate with the shaft 103 to press the second seal ring 402 during shaking, the sleeve-connecting piece 105 is sleeved on the shaft 103, the position of the sleeve-connecting piece 105 is fixed and then is positioned above the second seal ring 402, and the sleeve-connecting piece 105 is pressed downwards on the second seal ring 402. The socket 105 may be a nut for which an external thread is provided on the shank for facilitating engagement with the nut. In some preferred embodiments, two sockets 105 of nut structure are provided on the shank to prevent the nut from loosening. The thickness of the second sealing ring 402 is required to be sufficient not to obstruct the operation of the handle module, for example, the second sealing ring 402 cannot be set too thick, so as to avoid that the shaft of the handle module cannot be swung to the maximum position of the operable stroke due to the thickness of the second sealing ring when swinging.

In some embodiments, at least two annular recesses are provided on either of the left and right sides of the handle module, the at least two annular recesses on the same side being distributed in a concentric circular configuration from the inner ring to the outer ring on the handle module side. A sealing ring is correspondingly embedded in each annular recess.

In some embodiments, the first sealing ring 401 has a sawtooth structure on one side embedded in the annular recess, and the sawtooth structure on one side can prevent the first sealing ring from falling out of the annular recess when being assembled, compared with the sealing ring with an arc-shaped surface, so that the assembly problem and the subsequent equipment operation failure and safety problem caused by the assembly problem can be avoided. The sawtooth structure comprises at least two sawteeth, and any sawtooth is provided with a tip. As shown in fig. 2, the first sealing ring 401, which is located in an annular recess 1002 on the right side 1001 of the handle module, has a serrated shape on the side facing into the annular recess, and as shown in the cross-sectional configuration, comprises a plurality of serrations 40101 from top to bottom, each serration having a tip.
