Products Description
A combination drilling tool check valve is a structure with a valve core consisting of two forms:an arrow-type float valve and a fip foat valve.Not only can it reduce the risk of thread connection between two valve bodies,but also it can reduce the possibility of valve core damage caused by pressure fluctuations.When the drilling fluid circulates normally,the arrow-type combination drilling tool check valve is fully open.Once the cycle stops,the arrow-type float valve core closes under the action of its spring, preventing backflow from the drill bit nozzle.This type of valve core combination drilling tool check valve with an arrow-type foat valve on the upper part and a flip float foat valve on the lower part has higher reliability and safety than ordinary drilling tool check valves.
