Description
Technical field
The present invention relates to a kind of flow channel switching valve, and in particular to a kind of combined type flow channel switching valve.
Background technology
Flow channel switching valve is common device on fluid device, can easy, quickly realize that the flow direction of fluid converts, two
Runner can be separated individually, can also be connected.In the case where not dismantling associated devices, change flow direction, meet that liquid moves towards
Demand.Flow channel switching valve currently on the market is all one, and the pipeline or equipment that the valve of this integral type is connected with it are necessary
There is identical spacing, can not be in normal mounting when spacing has a small amount of change.Additionally, due to the requirement of sealing, inside is set
Have multiple-sealed, in switching, due to the extruding of sealing material, need very big power when rotating the spool of switching valve.To use
Make troubles.
Specifically, flow channel switching valve is made of handle, spool, sealing ring, clamp spring, plug at present.Feed liquor on valve body
Runner and to go out between liquid stream road be fixed, also must be identical with switching valve connection spacing；In addition also have on valve body and bypass
Runner, core-drawing hole, core-drawing hole reserve in order to which bypass flow channel is deviate from.Plug and sealing ring close core-drawing hole, prevent
Liquid leaks out.Two seals are placed on spool, for by hydraulic seal, during valve core rotation, sealing ring also with valve core rotation, by
Compressed in seal band, and this two seals and body cavity contact area are big, valve body needs larger power ability when rotating
Turn handle.
The content of the invention
The purpose of the invention is to easy to use, when installation, answers a variety of occasions, there is provided a kind of combined type flow channel switching valve.
The technical solution adopted by the present invention is：A kind of combined type flow channel switching valve, including handle, sealing cover, sealing ring, shell
Body one, supporting item, spool and housing two；
The housing one includes cylindrical surface, runner, location hole, cylinder, contiguous block and connecting pole；It is equipped with the housing one
Runner, the middle part of housing one are equipped with cylindrical surface, and the side on cylindrical surface stretches out cylinder, stretches out connection on the housing on the both sides of cylinder
Block, contiguous block are equipped with connecting pole, and the bottom of housing one is equipped with location hole；
The housing two includes cylindrical surface, runner, location hole, boss, connecting hole, contiguous block and circular hole；The housing two
Interior to be equipped with runner, the middle part of housing two is equipped with cylindrical surface, and boss is stretched out in the side on cylindrical surface, is connecting hole in boss, boss
Contiguous block is stretched out on the housing on both sides, contiguous block is equipped with circular hole, and the bottom of housing two is equipped with location hole；
The cylinder of the housing one is penetrated in the connecting hole of housing two, and the cylindrical exterior of housing one is equipped with sealing ring, sealing
Circle compression between cylinder and connecting hole forms sealing, and can be moved between cylinder and connecting hole；The connection of the housing one
Gap is left between the circular hole of column and housing two, docking can be realized according to the difference of the spacing of two housings；
The spool includes positioning column, crosses liquid mouth, runner, liquid pass hole, cylinder and pit；Runner is equipped with the spool,
The upper/lower terminal of spool is respectively cylinder, and the both sides of spool are pit, and positioning column is additionally provided with spool, crosses liquid mouth and liquid pass hole；
Spool is mounted in the housing one and housing two, one end of spool and the location hole of housing one, housing two connect
Connect, the other end of spool stretches out outside housing one, housing two through sealing cover and installs handle, and housing one and housing two-way are overstocked
Seal seals, and sealing ring is equipped between spool and housing one, housing two, the cylindrical surface of the sealing ring and housing one, housing two is close
Envelope coordinates, and sealing ring is positioned by supporting item.
Liquid enters housing, and liquid mouth and liquid pass hole, the spool no liquid imbalance in housing excessively through spool are brought
Pressure.Only have sealing ring to have friction when rotating handle, since sealing ring and spool contact area are small, reduce friction during rotation
Power.The spool runner is connected.
Apparatus of the present invention are made of two housings, and two parts spacing can adjust, between connection be to lean on two groups of positioning tables
Realize that there is internal liquid balance, and small, the rotation power-saving that rubs.
Beneficial effects of the present invention：
1. switching device is made of two housings, manufacture simplifies, and reduces mould requirement.
2. two housing spacing are adjustable, meet the different use occasion of spacing；
3. inside uses pressure balance principle；
4. reducing spool contact area, rotatable handle is laborsaving.
