The lower end of bar, the valve rod is fixedly connected with core, and first passage is offered on the valve deck, and the valve rod upper end is pierced by
The first passage is fixedly installed the oil cylinder for storing damping oil on the valve body, be fixedly installed in the oil cylinder every
Oil cylinder is divided into left shoe cream room and right shoe cream room by plate, the partition, and several through-holes, the left oil storage are offered on the partition
Chamber is connected with right shoe cream room by the through-hole, and the first connecting tube is fixedly installed on the cylinder body of the oil cylinder and is connect with second
Pipe, the first connecting tube right end side are connected with the left shoe cream room, the second connecting tube left end side and the right oil storage
Chamber is connected, and first piston is slidably provided in first connecting tube, and second connecting tube is slidably provided with second
Piston, the first connecting tube left end side are connected with the intake tunnel, the second connecting tube right end side and the water outlet
Channel is connected.
It is further improved to be: the first dynamic clamping head and quiet clamping head is provided between the first piston and the first connecting tube, it is described
The second dynamic clamping head and quiet clamping head is provided between second piston and the second connecting tube.
Further improved to be: first dynamic clamping head and quiet clamping head is the first spring, and second dynamic clamping head and quiet clamping head is second
Spring.
By using preceding solution, the beneficial effects of the utility model are: effectively the impact force of water hammer can be inhaled
Thermal energy is received and be converted to, the reciprocating impact of water hammer is avoided to damage valve body and pipe fitting.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment ball valve.
Specific embodiment
Now in conjunction with the drawings and specific embodiments, the present invention will be further described.
Revealed with reference to Fig. 1 the utility model embodiment is ball valve, including valve body 1, is set on the valve body 1
The valve deck 13 of side, the intake tunnel 11 radially opened up along valve body 1 and exhalant canal 12, be set to the intake tunnel 11 with it is described
For controlling the core 2 of fluid opening/closing between exhalant canal 12, the core 2 radially offers first fluid channel 21, institute
Stating first fluid channel 21 can be connected with intake tunnel 11 and exhalant canal 12, be located in the valve body 1 above the core 2
Portion is equipped with valve rod 22, and the lower end of the valve rod 22 is fixedly connected with core 2, offers first passage on the valve deck 13, institute
It states 22 upper end of valve rod and is pierced by the first passage,
It is fixedly installed the oil cylinder 3 for storing damping oil on the valve body 1, is fixedly installed partition in the oil cylinder 3
4, oil cylinder 3 is divided into left shoe cream room 31 and right shoe cream room 32 by the partition 4, offers several through-holes 41, institute on the partition 4
It states left shoe cream room 31 and is connected with right shoe cream room 32 by the through-hole 41, be fixedly installed first on the cylinder body of the oil cylinder 3
Connecting tube 61 and the second connecting tube 62, the 61 right end side of the first connecting tube are connected with the left shoe cream room 31, and described second
62 left end side of connecting tube is connected with the right shoe cream room 32, is slidably provided with first piston 5 in first connecting tube 61,
It is fixedly installed first connecting rod 51 on the first piston 5, the first connecting rod 51 is arranged in the first connecting tube 61, and described first
The first spring 52 is equipped on connecting rod 51,52 both ends of the first spring are fixedly installed on first connecting rod 51 and the first connection respectively
