Detailed Description

In order that the above objects, features and advantages of the utility model will be more clearly understood, a further description of the utility model will be rendered by reference to the appended drawings and examples. It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model, however, the present utility model may be practiced otherwise than as described herein, and therefore the present utility model is not limited to the specific embodiments of the disclosure that follow.

As shown in fig. 1-3, in the embodiment of the present utility model: the utility model provides a sealed stop valve, including disk seat 110, water inlet 120 and delivery port 130 have been seted up respectively to disk seat 110 bottom and left side, the water inlet 120 inner wall is provided with valve plate 140, and valve plate 140 is inside to be seted up through-hole 141, rivers flow through-hole 141 flow to delivery port 130, the shutoff of control through-hole 141 is the shutoff of control rivers promptly, the sealing member 150 has been inserted to the through-hole 141 below, sealing member 150 opens through-hole 141 promptly downwards, sealing member 150 upwards seals through-hole 141 promptly, and sealing member 150 top bearing is connected with valve rod 160, valve rod 160 threaded connection is in disk seat 110, the valve rod 160 top is connected with rotor 170, it drives valve rod 160 rotation to grip rotor 170, can control sealing member 150's rotation from top to bottom.

In a specific operation, when the through hole 141 is opened, an operator holds the rotating member 170 to rotate, so that the valve rod 160 can be driven to rotate, and under the action of the threaded connection of the valve rod 160 and the valve seat 110, the valve rod 160 can be driven to move downwards, the sealing member 150 is pushed to move downwards, and along with the downward movement of the sealing member 150, the gap leaked out of the through hole 141 is gradually increased, so that a medium can flow;
