Technical field
The present invention relates to a kind of pneumatic element.
Background technique
At present, the miniature valve of one of pneumatic element is supporting application in the equipment of quite a few, becomes oil, chemical industry, the indispensable accessory of textile manufacturing machine.Therefore, the designer of related domain is constantly studying, is manufacturing experimently this product, intends making this product can further obtain user's favor.
Publication number CN101101069A as the Chinese patent literature publication, application number 200610021361.X, disclosed a kind of " miniature valve " to society, this miniature valve comprises valve body and is installed in the driver in this valve body outside, this valve body comprises dunnage, valve body, diaphragm, rocking bar and driving component, this dunnage is pressed in and surrounds out a cavity on this valve body and with it, this diaphragm has elasticity, it is fixedly arranged in this cavity and this cavity is divided into fluid chamber and installation cavity, this rocking bar is a lever construction, it is installed in this installation cavity by fulcrum is rotatable, this rocking bar has the force side and first force side that branch is in the fulcrum both sides, this diaphragm is positioned on the movement locus of this first force side, this driver is by the force side of this rocking bar of driving component transmission, this valve body runs through and is provided with first, second channel, this is first years old, second channel is separated by first next door, and this diaphragm cover fully this first, the second channel and first next door.The invention of this part intends realizing that can there be residual volume in miniature valve in inside, and passage when switching the influence of convection cell less.
Summary of the invention
The invention provides a kind of miniature valve and assembling method, make it can reach compact structure, profile is small and exquisite, convenient manually control, and assembling is purpose comparatively easily.The present invention adopts following technological scheme to realize.
A kind of miniature valve, this valve comprise component compositions such as valve body, spool, bonnet, manual rod, moving core assembly, thimble assembly, coil block, and its main points are: the manual rod that is provided with in the valve body places the vertical of valve body; Coil block places the horizontal of valve body.Be provided with intake duct, air outlet flue, air outlet channel in the valve body, the seal spool plug is two and is provided with, and one places spool, and it two places moving core assembly, and the horizontal one side of the seal spool plug of one is adjacent with air outlet flue, and vertical one side is adjacent with air outlet channel; And another side is inserted in the iron core spring and is butted on bonnet mutually, and bonnet is connected with clamp with valve body, constitutes the sealing disjunctor by the 2nd O shape circle; Its seal spool of two plugs in moving core assembly, it laterally adjacent with intake duct.Between spool that is provided with in the valve body and bonnet, manual rod, the thimble assembly clamp is set, constitutes assemblying body closely; The manual rod that is provided with in the valve body places the vertical of valve body, and manual rod and valve body constitute the sealing disjunctor by O shape circle, are provided with manual spring in manual rod.Coil block is with transversely arranged, and coil block offsets with placing the thimble assembly in the valve body, and thimble assembly and valve body constitute the sealing disjunctor by the 2nd O shape circle.Valve body simultaneously is provided with suction port, relief opening, air outlet, and the suction port of this face of valve body, air outlet connect with the parts of gas equipment, and constitute the sealing disjunctor by square plain cushion.
A kind of assembling method of miniature valve, this valve comprise component compositions such as valve body, spool, bonnet, manual rod, moving core assembly, thimble assembly, coil block, and the main points of this assembling method are: the manual rod that is provided with in the valve body places the vertical of valve body; Coil block places the horizontal of valve body.Be provided with intake duct, air outlet flue, air outlet channel in the valve body, the seal spool plug is two and is provided with, and one places spool, and it two places moving core assembly, and the horizontal one side of the seal spool plug of one is adjacent with air outlet flue, and vertical one side is adjacent with air outlet channel; And another side is inserted in the iron core spring and is butted on bonnet mutually, and bonnet is connected with clamp with valve body, constitutes the sealing disjunctor by the 2nd O shape circle; Its seal spool of two plugs in moving core assembly, and it laterally adjacent with intake duct seals gas-entered passageway in the moving iron core sealing plug of spring control when switching on.
Advantage of the present invention is that volume is little, consumptive material is few, and compact structure is convenient to manual control, and it is comparatively convenient to assemble.Be suitable for the supporting application of oil, chemical industry, textile manufacturing machine.

Embodiment
In conjunction with shown in Figure 1, the present invention is an example with miniature valve model WF23-1C, during the coil block 15 access failure power supplys of this valve, suction port 201 is in closed condition, because the moving iron core spring 14 that is arranged in the coil block is in extended configuration, the elastic force of spring withstands conduit assembly 13 and moving core assembly 12, makes inlet close.And the moving iron core in power line 16 energising back is opened by electromagnetic attraction, relief opening 202 by valve core spring 4 jack-up of bonnet 5 after, the air inlet of suction port 201 203 is flowed out from the air outlet by cavity.Valve body 2 connects with the parts of gas equipment, and when coil block connects power supplys by power line 16, when sealing plug 6 will be finished in the suction port air inlet according to the program that is provided with in the spool after the energising, gives vent to anger in the air outlet, and the relief opening exhaust realizes the function of this miniature valve.
