Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Examples
Referring to fig. 1 to 6, the present embodiment relates to a manual liquid valve, which includes a valve body 1, a rotating shaft 2 rotatably and hermetically installed at the center of the valve body 1, a rotating disc 3 rotatably sleeved in the valve body 1, a fixed disc 4 hermetically and fixedly installed at the rear end of the valve body 1, and an elastic member 5 sleeved on the rotating shaft 2 and having two ends respectively pressing against the valve body 1 and the rotating disc 3; the rotary table 3 is slidably sleeved on the rotary shaft 2, the rotary shaft 2 drives the rotary table 3 to synchronously rotate, and the rotary table 3 and the fixed table 4 are mutually pressed; a water outlet hole 11 is formed in the front end face of the valve body 1, fan-shaped through holes 43 are formed in the fixed disc 4 and the rotary disc 3, and the water outlet hole 11 is communicated with the fan-shaped through holes 43 of the rotary disc 3; when the rotating shaft 2 drives the rotating disc 3 to rotate, the communication area of the fan-shaped through holes 43 between the fixed disc 4 and the rotating disc 3 is gradually increased or decreased to form a water flow control structure. The tail end of the valve body 1 is connected with a water inlet pipe. The water inlet pipe is communicated with the fixed disk 4 and the fan-shaped through hole 43. The elastic member 5 is a spring.
In use, by rotating the rotating shaft 2, the rotating shaft 2 drives the rotating disc 3 to rotate, so that the fan-shaped through holes 43 on the rotating disc 3 rotate relative to the fan-shaped through holes 43 on the fixed disc 4. When the fan-shaped through holes 43 of the rotating disc 3 are partially overlapped with the fan-shaped through holes 43 of the fixed disc 4, water in the water inlet pipe enters the valve body 1 through the partially overlapped area and flows out of the water outlet holes 11 to start supplying water for external equipment. As the rotary disk 3 continues to rotate, the overlapping area of the fan-shaped through holes 43 of the rotary disk 3 and the fan-shaped through holes 43 of the fixed disk 4 becomes larger and larger until the overlapping is completed, and the flow rate of the water flowing out of the water outlet hole 11 increases until the maximum value is reached. Then, as the rotary disc 3 continues to rotate, the overlapping area of the fan-shaped through holes 43 of the rotary disc 3 and the fan-shaped through holes 43 of the fixed disc 4 becomes smaller and smaller until the overlapping area is zero, and the flow rate of the water flowing out of the water outlet hole 11 is reduced continuously until the water is completely closed. Whole process discharge can be by linear regulation to the output of crescent or reduction water yield has solved current fire control relief valve and can only open or close entirely, and can't carry out the problem adjusted to discharge size.
Because this structure adopts carousel 3 to rotate and the fan-shaped through-hole 43 of control carousel 3 and the fan-shaped through-hole 43's of fixed disk 4 intercommunication area, make pivot 2 just can realize the fan-shaped through-hole 43 of carousel 3 and the fan-shaped through-hole 43 of fixed disk 4's intercommunication and close when rotating the round at most, switching speed is fast, adjust and control efficiency is high, solved and present because screw thread transmission's inefficiency, need rotate many rings and just can open and close the valve, the time of needs is longer, can not be opened fast when taking place the condition of a fire, lead to the problem of fire rescue's delay easily.
As shown in fig. 2, 4 and 6, the tail end of the rotating shaft 2 is a square shaft 21, a square hole 31 corresponding to the square shaft 21 is formed in the center of the rotating disc 3, and the square shaft 21 is slidably sleeved in the square hole 31. The elastic piece 5 presses the rotary disc 3 against the fixed disc 4, so that the rotary disc 3 slides towards the fixed disc 4 and presses the fixed disc 4, and sealing between the rotary disc 3 and the fixed disc 4 is realized. Due to the fact that the square shaft 21 is connected with the square hole 31 in a matched mode, when the square shaft 21 rotates, the square shaft 21 can drive the rotary disc 3 to rotate synchronously, the size of the communication area of the fan-shaped through hole 43 of the rotary disc 3 and the fan-shaped through hole 43 of the fixed disc 4 is further controlled, and the rotary disc type rotary disc has the advantages of being simple in structure, convenient to install and fast.
In order to improve the sealing performance between the rotary disk 3 and the fixed disk 4 and prevent water from flowing into the valve body 1 from the gap between the fixed disk 4 and the rotary disk 3, a sealing member is arranged between the rotary disk 3 and the fixed disk 4.
The fixed disk 4 is provided with a boss 41, the boss 41 is in contact with the rotary disk 3, and the length of the boss 41 is equal to the diameter of the fixed disk 4. The design of this boss 41 can reduce the area of contact between fixed disk 4 and the carousel 3 for carousel 3 can receive littleer frictional resistance when rotating, has reduced pivot 2 pivoted resistance, has improved the portability, the smoothness nature and the convenience of control.
In order to improve the sealing performance between the rotary disk 3 and the boss 41 and prevent water from flowing into the valve body 1 from the gap between the boss 41 and the rotary disk 3, the sealing member is arranged on the boss 41 and is connected with the rotary disk 3 in a sealing manner.
The front part of the rotating shaft 2 is provided with a limit pin 22. The stopper pin 22 serves to prevent the rotation shaft 2 from sliding and shifting, and the open and close state of the fan-shaped through hole 43 of the turntable 3 with respect to the fan-shaped through hole 43 of the fixed disk 4 can be indicated by the stopper pin 22.
The front end face of the valve body 1 is provided with a limiting block 12. The limiting block 12 is matched with the limiting pin 22 and is used for displaying the opening and closing state of the fan-shaped through hole 43 of the rotary disc 3 relative to the fan-shaped through hole 43 of the fixed disc 4.
An annular groove 13 is formed in the valve body 1, a sealing ring 14 is sleeved in the annular groove 13, and the sealing ring 14 presses the rotating shaft 2. The packing 14 prevents water in the valve body 1 from leaking out through a gap between the rotary shaft 2 and the valve body 1.
The included angle of the fan-shaped through holes 43 is less than 180 degrees. Preferably, the included angles of the two fan-shaped through holes 43 are equal and less than 140 degrees.
The above disclosure is only a preferred embodiment of the present invention, and certainly should not be taken as limiting the scope of the invention, which is defined by the claims and their equivalents.
