Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the utility model. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.

It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict. The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.

The utility model provides a take marine butterfly valve of hydraulic actuator, as shown in figure 1, still includes sealing washer 8, sealing washer 8 assembles valve plate 2 with between the disk seat 1, sealing washer 8 is the rubber material, and sealing washer 8 can play the sealed effect when valve plate 2 closes. The surface of the valve seat 1 is coated with an anticorrosive coating and can protect the valve seat 1, flange plates are welded on the front side and the rear side of the valve seat 1, so that the butt joint with a pipeline is facilitated, a valve rod is connected above the valve plate 2 and drives the valve plate 2 to rotate, and therefore the valve plate 2 is opened and closed.

As shown in fig. 1, 2 and 3, the reinforcing member 3 is located inside the valve seat 1, a liquid inlet head and a liquid outlet head are arranged on a side surface of the hydraulic actuator 4, the manual actuator 5 includes a hand wheel and a switching rod, and the manual actuator 5 can control opening and closing of the valve plate 2 when the hydraulic actuator 4 fails. The top of the stable supporting block 7 is bonded with a flexible pad 9, the flexible pad 9 is abutted to the lower portion of the hydraulic actuator 4, and the flexible pad 9 is made of silica gel and can avoid damage to the hydraulic actuator 4.

When in use: at first with disk seat 1 and pipeline butt joint, it can play the stable effect of support to hydraulic actuator 4 from the side to stabilize the tray 7, and flexible pad 9 can avoid at the in-process of butt, damage hydraulic actuator 4, thereby can improve the stability when hydraulic actuator 4 uses, then can remote control the opening and close of valve plate 2 through hydraulic actuator 4, reinforcement 3 can promote the tightness of valve plate 2, thereby the pressure that bears the pipeline medium that can be better, when hydraulic actuator 4 breaks down, can rotate the switching pole, control opening and close of valve plate 2 through manual actuating mechanism 5, the security is high.

The scheme can also comprise a filter screen which is clamped in the liquid inlet head of the hydraulic actuator 4; the filter screen can filter impurity, can avoid impurity to get into hydraulic actuator 4's inside to can reduce hydraulic actuator 4's fault rate.
