It is provided with abutment platform, abuts and is arranged with spring 12 outside column 9, the both ends of spring 12 are abutted with abutment platform and electromagnet 5 respectively
Cooperation, when spring 12 in the raw when, solenoid valve is in close state.
Referring to Figures 1 and 2, the one end for abutting column 9 towards electromagnet 5 offers jack 8, and jack 8 is along the length for abutting column 9
Spend direction setting；Meanwhile mating buffer rubber gasket 7 in jack 8, buffer rubber gasket 7 is for reducing electromagnet 5 and abuts column
9 support noise when touching.Specifically, the T-shaped setting in the cross section of buffer rubber gasket 7, buffer rubber gasket 7 includes plug division 71 and supports
Socket part 72, plug division 71 is cylindrical, and abutting part 72 is in the form of a circular plate, and one end of plug division 71 is vertically connected at abutting part 72
A side surface, plug division 71 and jack 8 are mating；Meanwhile plug division 71 and abutting part 72 are integrally formed, such setting
Facilitate the manufacture processing of buffer rubber gasket 7.
Meanwhile the rounded setting in end of the plug division 71 far from abutting part 72, facilitate plug division 71 to be inserted into jack 8,
When plug division 71 is completely inserted into jack 8, the surface that abutting part 72 is connect with plug division 71 and the end face of spool 2 offset.
When electromagnet 5 is with the actuation of column 9 is abutted, electromagnet 5, which supports, encounters abutting part 72, and abutting part 72 is capable of providing sufficient
Area is supported for electromagnet 5 and is touched, and then can slow down electromagnet 5 and the collision that occurs when abutting the actuation of column 9, to reduce noise.
Specifically, the length range of plug division 71, in 6-8mm, in the present embodiment, the length of plug division 71 is 6 mm, this
The magnetism of buffer rubber gasket 7 is in preferable state under length, guarantees the good working performance of solenoid valve；In addition, abutting part 72
Thickness range in 0.15-1.5mm, in the present embodiment, abutting part 72 with a thickness of 1.6 mm, buffer rubber gasket under this thickness
7 noise reduction effect is more excellent, so that for electromagnet 5 when to socket part 72 is hit against, noise is lower during the work time for solenoid valve.
Working principle: when electromagnet 5 powers off, by being set in the spring 12 abutted outside column 9, spring 12 makes electromagnet 5
Stress is simultaneously connected to import 3, abuts column 9 when the energization of electromagnet 5 is attracted electromagnet 5, spool 2 is made to overcome the elastic force of spring 12 simultaneously
Keep valve in the open state, the folding of valve can be realized by controlling the power on/off of an electromagnet 5 by spring 12.
For electromagnet 5 with when abutting column 9 and being attracted, electromagnet 5, which supports, encounters abutting part 72, abutting part 72 can slow down electromagnet 5 with abut column 9

Mesa-shaped setting, and elasticity squeezes the larger bottom surface of item 10 towards abutting part 72, the elasticity squeezes item 10 and pushes against in the hole of jack 8
Wall.
Plug division 71 be inserted into jack 8, by elasticity squeeze item 10 deformation occurs abutting in jack 8 hole wall and will delay
Rush that rubber pad 7 is firm to be plugged in jack 8；Elasticity squeezes the larger bottom surface of item 10 towards abutting part 72, i.e., when insertion buffers
When rubber pad 7, simultaneously Relative sliding is abutted at the lateral surface and the opening's edge of jack 8 of elasticity extruding item 10, consequently facilitating elasticity is squeezed
Press strip 10 is squeezed into jack 8, and the more labor-saving convenience of buffer rubber gasket 7 is installed.
Referring to Fig. 3 and Fig. 4, the outer edge of end face of the abutting part 72 far from plug division 71 opens up that there are two semicircular bayonets
11, and length direction of two bayonets 11 along plug division 71 is centrosymmetric distribution.The setting of bayonet 11 facilitates staff to tear open
Buffer rubber gasket 7 is unloaded, convenient for the maintenance and replacement of later period buffer rubber gasket 7.
In addition, socket part is arc surface away from the end face of plug division 71, arc surface is from plug division 71 to the direction of abutting part 72
Bending protrusion, the setting of arc surface improve the comfort level of staff's hand when installing buffer rubber gasket 7.
Above-described embodiment is only the explanation to the utility model, is not limitations of the present invention, this field
Technical staff can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but only
It will be in the scope of the claims of the utility model all by the protection of Patent Law.
