Description
Technical field
The present invention relates to valve technology field, particularly to a kind of two-bit triplet magnetic valve.
Background technology
Two-position three-way valve is one of valve for being most widely used in various hydraulic pressure, pneumatic circuit, especially with electricity
Magnet valve technology is continued to develop, and it is even more the occasion such as to automatically control by substantial amounts of be used in.
Gearshift magnetic valve is relatively conventional one kind in magnetic valve.At present, in the market has a kind of two-bit triplet magnetic valve just
Used as gearshift magnetic valve, it includes housing, electromagnetic drive, valve and valve base etc., wherein electromagnetism drives
Dynamic component includes coil block, back-moving spring and dynamic iron core, and valve base is provided with corresponding import, and valve is located on valve base simultaneously
And active path is limited by guide holder, push rod is provided between dynamic iron core and valve.The two-bit triplet magnetic valve is normally close valve, just
Under beginning state, coil block no power, dynamic iron core pushes down push rod in the presence of back-moving spring, push rod and then props up valve, from
And close the import on valve base.When coil block is powered, dynamic iron core is inhaled dynamic, so as to be conceded for the axial movement of push rod
Space, now valve will be opened in the presence of inlet pressure, so as to realize the conducting of respective channels.
Due to being that the aperture of valve is controlled using the cooperation of push rod and dynamic iron core, therefore the overall length of push rod and dynamic iron core
And the active strokes of dynamic iron core just become the key factor of control inlet flow rate precision, but in the process of the manufacturing
In, due to the difference of parts batch etc., the inlet flow rate of above-mentioned two-bit triplet magnetic valve is difficult to realize to be precisely controlled, and is made
During making, once there is push rod or dynamic iron core length variation or assembling deviation, then the workability of valve can be directly influenced
Can, reduce the reliability of valve.In view of the foregoing, two-bit triplet magnetic valve mentioned above exist precision it is whard to control,
The big defect of manufacture difficulty.
The content of the invention
It is an object of the invention to provide a kind of two-bit triplet magnetic valve, to solve the precision of above-mentioned two-bit triplet magnetic valve
It is not easily-controllable, the problem of manufacture difficulty is big.
In order to solve the above problems, two-bit triplet magnetic valve of the invention uses following technical scheme：Two-bit triplet electromagnetism
Valve, including housing, electromagnetic drive, back-moving spring, dynamic iron core, push rod, valve and valve base, the dynamic iron core it is close
The end of push rod, which is provided with stopper slot, stopper slot, is provided with adjust pad, and the respective end of push rod is inserted into the stopper slot.
Buffer sublayer is additionally provided with the stopper slot, adjust pad is located between the bottom land of stopper slot and buffering steel ball, buffering
The outer surface of the side at least contacted with push rod of son is sphere.
The buffer sublayer is buffering steel ball.
The housing includes two parts of fixed seal connection, and a part for housing is provided with adpting flange, another part
For plug-in structure, its outer peripheral face is provided with all surface seal structures.
The valve is steel ball valve.
The electromagnetic drive is wet electro-magnet part.
Because one end of the close push rod of the dynamic iron core of the two-bit triplet magnetic valve of the present invention is provided with stopper slot, stopper slot
Provided with adjust pad, and the respective end of push rod is located in the stopper slot, therefore, during manufacture, push rod and dynamic
Length dimension deviation present in iron core can be made up by adjust pad, so that the finishing of substandard product can be realized, and then
The problem of solving precision that existing two-bit triplet magnetic valve is present whard to control and big manufacture difficulty.
Further, because the fit precision between dynamic iron core and coil block is limited, in the process of dynamic iron core activity
In, what it was difficult to avoid that occurs beat, after using the outer surface of the side at least contacted with push rod for the buffer sublayer of sphere,
Even if the situation of beat occurs in dynamic iron core, it also can accurately ensure the stroke accuracy of push rod and valve；Using buffering steel
In the case that ball is as buffer sublayer, buffer sublayer can automatically live under the suction of electromagnetic drive with dynamic iron core
It is dynamic.
