Description
Technical field
The present invention relates to hydraulic valve technology more particularly to a kind of throttle valves.
Background technique
Throttle valve is by changing throttling section or chock length to control the valve of fluid flow.By throttle valve and unidirectionally
Valve series connection is then combined into one-way throttle valve.At present one-way throttle valve on the market mostly all can not manual adjustment, all pass through
The flow velocity of internal liquid is automatically controlled, can not the suitable speed of artificial selection under necessary condition.Section current simultaneously
Stream valve does not have the function of self-cleaning, and duration will lead to valve body blocking or obstructed phenomenon.
The prior art improves such as that application No. is disclose in the Chinese utility model patent of CN201120291512.X can
The sleeping top throttle valve of length of fall off rate is controlled, it includes throttle valve seat, is mainly technically characterized by being equipped with throttling in throttle valve bore
Valve spring pushes up a steel ball on throttle valve spring, and throttle valve bore is equipped with out the big channel of liquid, throttle valve bore internal segment stream valve bullet outward
Spring side is equipped with small-bore channel again；Liquid sucting port strainer is equipped at the throttle valve seat feed liquor；The small-bore channel diameter is
0.3mm.When throttle valve zero load, speed is fast, and liquid directly comes out from big channel.When pressure is big, volume carry when, steel ball downwardly against
Spring, liquid return liquid from small-bore channel, slowly lower, increase safety.But the throttle valve can not carry out artificial adjusting,
It is controlled completely by internal flow channel for liquids speed, artificial suitable optimal speed can not be carried out if necessary.
The prior art improves such as that application No. is disclose unidirectional section in the Chinese utility model patent of CN91203797.0
Valve is flowed, which has the characteristics that throttle valve lever is coaxial with airflow channel, so that its profile volume be made to greatly reduce；Again due to valve
Both ends all have pipe fitting, so that installation is extremely convenient, saves pipe fitting and mounting rack, reduce costs.But it can not
Improving valve body leads to blocking or obstructed problem due to working long hours.
