Hydraulic pump sharing:
The principle of the hydraulic balance valve is the anti-regulation in the valve body. When the pressure at the inlet is increased, the diameter is automatically reduced to reduce the flow rate change and vice versa. If the connection is reversed, this adjustment system will not work. Moreover, the regulating valve plate is directional, and the reverse pressure can even reduce or even close the flow.
Since the balance valve is installed for better heating, there is no problem of reverse installation. If it is a disguise, it is a human error that will of course be corrected. The balance valve belongs to the category of regulating valve. Its working principle is to change the flow resistance of the fluid flowing through the valve by changing the gap (that is, the opening) of the valve core and the valve seat to achieve the purpose of regulating the flow rate. The balance valve is equivalent to a throttling element whose local resistance can be changed. For incompressible fluids, the flow equation is available.
