Structure of one-way throttle valve and ordinary throttle difference

Structure of one-way throttle valve and ordinary throttle difference

From the structural point of view, there seems to be no difference. Ordinary throttle valve can flow into P2 port through the triangular groove (throttle port) on the valve core when the oil enters from P1 port. When the oil enters from P2 port, it can apply pressure on the right end face of the valve core to make the valve core move and flow directly into P1 port. The difference is not the degree of hard and soft spring, one-way throttle valve is a soft spring, ordinary throttle valve is a hard spring.
 
Function of one-way throttle valve and ordinary throttle difference
 
One-way valve throttle valve and the difference between the one-way valve. When the oil enters from the P1 port, it can flow into P2 port through the triangle groove (throttle port) on the valve core. When the oil enters from P2 port, it can apply pressure on the right end face of the valve core to make the valve core move and flow directly into P1 port. One-way throttle valve has the existence of one-way valve, when the oil from P2 into P1 port, due to the throttle resistance, oil directly through the one-way valve (very few through the throttle valve) flow back to P1 port, this is the basic difference between the two! Can also be understood as the ordinary one-way valve its two-way throttle speed regulation role, and one-way throttle valve only its a one-way speed regulation role.
 
The above is about one-way throttle valve and the introduction of the difference between the ordinary throttle valve, I hope we can better apply it in life after understanding, and I hope we can choose different throttle valve according to different circumstances.
