Preferably, the medium flow hole is a stepped hole, and the medium flow hole has different hole diameters on both sides of the throttle plate.
Preferably, the aperture of the medium flow through hole on the liquid inlet side is larger than that on the liquid outlet side.
As a preferable scheme, a positioning boss is arranged on the adjusting screw, bearings are arranged on two sides of the positioning boss in the mounting seat, and a gland for compressing the bearings is arranged at the end part, close to the adjusting screw, of the mounting seat.
Preferably, the gland is provided with a direction indicator for indicating the rotation of the adjusting screw to open or close the valve body.
Preferably, the end of the adjusting screw is detachably provided with a driving rod for driving the adjusting screw to rotate.
As a preferred scheme, the lifting block is provided with an indicating rod, and the transmission box body is provided with an opening scale matched with the indicating rod.
The utility model has the beneficial effects that:
the adjusting screw rod is rotated through the driving rod or other tools to drive the square lifting block to move up and down together with the throttle plate, so that the size of a medium circulation hole in the valve body is changed, and throttling and flow rate adjusting are realized.
Because the adjusting screw is provided with the positioning boss, the bearings are arranged on the two sides of the positioning boss in the mounting seat, and the end part of the mounting seat, which is close to the adjusting screw, is provided with the gland for compressing the bearing, so that the mounting and the positioning are convenient, the assembly difficulty is reduced, and the mounting precision is improved.
The gland is provided with a direction instruction for indicating to rotate the adjusting screw to open or close the valve body, so that the operation of a user is facilitated.
Because the end part of the adjusting screw rod is detachably provided with the driving rod for driving the adjusting screw rod to rotate, the adjusting screw rod can rotate more labor-saving.
Because the lifting block is provided with the indicating rod, the transmission box body is provided with the opening scale matched with the indicating rod, the opening degree can be observed more intuitively, and the valve can be adjusted more conveniently and accurately.
