The further improvement is that: the rotating device comprises a worm wheel and a worm, a sealing box is arranged on the valve body, the worm wheel is sleeved on the rotating rod, the worm rotates to penetrate through the sealing box, one end of the worm is in meshed transmission with the worm wheel, and the other end of the worm penetrates out of the sealing box.
The further improvement is that: the baffle is arranged in a spherical shape on the contact surface of the baffle with the water hammer.
The further improvement is that: the baffle is provided with a plurality of Z-shaped hammer eliminating channels penetrating through the baffle.
The further improvement is that: the water inlet end of the hammer eliminating channel is provided with a first filter screen for preventing the hammer eliminating channel from being blocked, and the water outlet end of the hammer eliminating channel is provided with a second filter screen for preventing the hammer eliminating channel from being blocked.
The further improvement is that: the water hammer is characterized by further comprising a screw, the screw is arranged on the baffle, the screw is positioned at the other end of the water hammer contact surface, and the screw is in threaded connection and penetrates through the connecting rod.
The further improvement is that: and a hand wheel is arranged outside the sealing box on the worm.
By adopting the technical scheme, the utility model has the beneficial effects that:
Simple structure has waterproof hammer function, can improve life. When the water hammer protection device is used, the baffle is blocked in the water inlet channel, then when the knife switch is closed to generate the water hammer, the water hammer is hit on the baffle, and the water hammer is prevented from being directly hit on the valve plate, so that the valve plate is protected, and the service life of the valve plate is prolonged. Then when the disconnecting link is opened, the baffle returns to the original position, so that when the disconnecting link is opened, the baffle can not block the water flow of the water inlet channel, and the use of the disconnecting link is facilitated.
Drawings
FIG. 1 is a schematic diagram of a cut-away structure of a valve body for sand casting of a knife gate valve body according to an embodiment of the present utility model.
Description of the embodiments
The utility model will now be further described with reference to the drawings and specific examples.
Referring to fig. 1, the embodiment of the utility model discloses a valve body for sand casting of a knife gate valve body, which comprises a valve body 1, a water inlet channel 2 and a water outlet channel 3 which are arranged on the valve body 1, and a baffle plate 4 for blocking a water hammer, wherein a connecting rod 5 is arranged on the baffle plate 4, a rotating rod 6 is rotatably arranged on the valve body 1, one end of the rotating rod 6 is connected with the connecting rod 5, the other end of the rotating rod 6 penetrates out of the valve body 1, a worm wheel 7 and a worm 8 which are used for driving the rotating rod 6 to rotate so as to drive the baffle plate 4 to rotate are arranged on the valve body 1, a sealing box 9 is arranged on the valve body 1, the worm wheel 7 is sleeved on the rotating rod 6, the worm 8 is rotatably arranged on the sealing box 9 in a penetrating manner, one end of the worm 8 is meshed with the worm wheel 7, and the other end of the worm 8 penetrates out of the sealing box 9. When the knife switch is used, the worm 8 is rotated firstly, the worm 8 drives the worm wheel 7 to rotate, the worm wheel 7 drives the rotating rod 6 to rotate, and the rotating rod 6 drives the connecting rod 5 to rotate, so that the baffle 4 is driven to rotate 90 degrees, the baffle 4 is blocked in the water inlet channel 2, and then when the knife switch is closed to generate a water hammer, the water hammer is hit on the baffle 4, and the water hammer is prevented from being directly hit on the valve plate, so that the valve plate is protected, and the service life of the valve plate is prolonged. Then when the knife switch is to be opened, the worm 8 is reversed, and the worm 8 drives the baffle 4 to rotate for 90 degrees to return, so that the baffle 4 can not block the water flow of the water inlet channel 2 when the knife switch is opened, and the use of the knife switch is facilitated.
In order to reduce the acting force of the water hammer on the baffle plate 4, the baffle plate 4 is arranged in a spherical shape 11 on the contact surface with the water hammer.
