Detailed Description

The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

Example (b):

referring to fig. 1, 2 and 3, the embodiment of the present invention discloses a ball valve for preventing a water hammer, which includes a valve body 1, the valve body 1 is provided with a water inlet channel 11 and a water outlet channel 12, a valve plate 13 disposed between the water inlet channel 11 and the water outlet channel 12 and used for controlling fluid, the valve plate 13 is provided with a fluid channel 131, the fluid channel 131 can be communicated with the water inlet channel 11 and the water outlet channel 12, a lower valve rod 14 for controlling the rotation of the valve plate 13 is disposed inside the valve body 1 above the valve plate 13, the lower end of the lower valve rod 14 is fixedly connected with the valve plate 13, the upper end of the lower valve rod 14 penetrates out of the valve body 1, a housing 31 is disposed on the valve body 1, the upper end of the lower valve rod 14 is disposed in the housing 31, the upper end of the lower valve rod 14 is downwardly provided with a spline hole, the lower end of the upper valve rod 2 is a spline shaft capable of being, the integral key shaft can slide from top to bottom and set up in the splined hole, the upper end of going up valve rod 2 is worn out casing 31, the both sides of going up valve rod 2 are provided with guide block 21 respectively, casing 31's inner wall has been seted up twice and has been risen slide 32, twice rise and communicate each other through perpendicular slide 33 between the slide 32, guide block 21 can slide and set up in rising slide 32 and perpendicular slide 33, and the UNICOM department that rises slide 32 top and perpendicular slide 33 can be slided from left to right and be provided with slider 4, slider 4 can slide from left to right and set up in the top of rising slide 32, be provided with spring 41 between slider 4 and the casing 31, the spring 41 both ends respectively with slider 4 and casing 31 fixed connection, slider 4 also can dodge perpendicular slide 33 and the intercommunication department of rising slide 32.

In order to make the guide block 21 slide into the vertical slide way 33 smoothly, a guide surface for making the guide block 21 better enter the vertical slide way 33 is arranged on one surface of the slide block 4 which can be in contact with the guide block 21.
