Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the utility model, and not restrictive of the full scope of the utility model. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.
A specific embodiment of the present invention provides a ball valve cartridge, as shown in fig. 1, including: the valve core comprises a valve core body 1, a first through groove 2 and a second through groove 3. Wherein first logical groove 2 and the equal level setting in second logical groove 3 are on case body 1, and just first logical groove 2 and the logical groove 3 of second all run through case body 1 and set up. The first through groove 2 and the second through groove 3 are arranged side by side, and the first through groove 2 and the second through groove 3 are communicated to form a whole through groove.
The valve core body 1 is rotatably arranged in the valve body, the first through groove 2 and the second through groove 3 are blocked by the valve body in the process of rotating the valve core body 1, namely, water flow cannot pass through the valve body, the first through groove 2 and the second through groove 3 are not completely blocked, and then the water flow flows through the part leaked from the first through groove 2 and the second through groove 3, so that the size of the water flow is controlled.
Regarding the specific structure of the first through groove 2 and the second through groove 3, the first through groove 2 is vertically longer than the second through groove 3, that is, the length of the first through groove 2 is longer than the second through groove 3 in a direction vertically perpendicular to the length direction of the first through groove 2. The second through groove 3 is longer than the first through groove 2 in the transverse direction, that is, the second through groove 3 is longer than the first through groove 2 in the direction transverse to the length direction of the first through groove 2.
When the ball valve needs to be closed, the valve core body 1 is rotated, the first through groove 2 and the second through groove 3 are gradually blocked, one side, away from the second through groove 3, of the first through groove 2 is firstly blocked, and after the first through groove 2 is completely blocked, one side, close to the first through groove 2, of the second through groove 3 is firstly blocked until the second through groove 3 is completely blocked. Because the length of the first through groove 2 is longer than that of the second through groove 3 in the direction vertical to the length direction of the first through groove 2, and the length of the second through groove 3 is longer than that of the first through groove 2 in the direction transverse to the length direction of the first through groove 2, in the process that the first through groove 2 is gradually blocked, a relatively short rotation stroke can obtain a relatively large flow reduction amount, and in the process that the second through groove 3 is gradually blocked, a relatively long rotation stroke obtains a relatively small flow reduction amount.
So set up, when beginning to close the ball valve, rotate case body 1 and can reduce the flow fast in the short time, reach the effect that subtracts the class fast. Then, the valve core body 1 is rotated to slowly reduce the flow in a longer time, so that the effect of stably reducing the flow is achieved.
As an optional implementation manner, in the specific embodiment of the present invention, as shown in fig. 1, when the first through groove 2 is provided, it is ensured that the vertical length of the first through groove 2 sequentially increases from one end away from the second through groove 3 to one end close to the second through groove 3, that is, the height of the first through groove 2 sequentially increases in the direction in which the rotary valve core body 1 closes the ball valve. So set up, when beginning to close the ball valve, rotate case body 1 and can reduce the flow fast in the short time, reach the effect that reduces the flow fast, the flow reduction volume in the unit interval crescent simultaneously for when first logical groove 2 is gradually blocked, it is faster to reduce the flow.
As an optional implementation manner, in the specific embodiment of the present invention, as shown in fig. 1, when the second through groove 3 is provided, it is ensured that the vertical length of the second through groove 3 sequentially increases from one end away from the first through groove 2 to one end close to the first through groove 2, that is, the height of the second through groove 3 sequentially decreases in the direction in which the rotary valve core body 1 closes the ball valve. So set up, when beginning to close second through-groove 3, rotate case body 1 and can slowly reduce the flow in longer time, reach the effect that steadily reduces the flow, the flow reduction volume in the unit interval reduces gradually simultaneously for when first through-groove 2 is gradually blocked, it is slower to reduce the flow.
As an optional implementation manner, in a specific embodiment of the present invention, as shown in fig. 1, a mounting hole 4 is disposed at the top end of the valve core body 1, when the valve core is mounted, the valve rod is fixed in the mounting hole 4, and the valve rod is rotated to drive the valve core body 1 to rotate.
As an optional implementation manner, in a specific embodiment of the present invention, as shown in fig. 1, a rotation hole 7 is disposed at the bottom end of the valve core body 1, a rotation shaft is disposed on the bottom surface inside the valve body, and the rotation hole 7 at the bottom end of the valve core body 1 is sleeved on the rotation shaft, so that the valve core body 1 can be rotatably connected inside the valve body.
A specific embodiment of the present invention provides a ball valve, including: the valve core, wherein the valve core is above arbitrary ball valve core.
As an optional implementation manner, in an embodiment of the present invention, as shown in fig. 2, the ball valve further includes:
a valve body 5, wherein the valve body 5 comprises: the water inlet 51, the cartridge 52 and the water outlet 53, wherein a first side of the cartridge 52 is communicated with the water inlet 51, and a second side of the cartridge 52 is communicated with the water outlet 53, so that the water inlet 51 is communicated with the water outlet 53 through the cartridge 52. The valve core is rotatably connected in the valve core bin 52, when the valve core is rotated, and the through groove on the valve core is blocked, the water inlet 51 and the water outlet 53 are cut off, and water flow cannot flow from the water inlet 51 to the water outlet 53; when the through groove on the valve core is opened, the water inlet 51 is communicated with the water outlet 53 through the through groove, and water flow can flow from the water inlet 51 to the water outlet 53.
Alternatively, in the embodiment of the present invention, as shown in fig. 2, the ball valve further includes a stem 6, and the valve body 5 further includes a stem groove, and the stem groove is opened on the sidewall of the cartridge chamber 52. The valve rod 6 penetrates into the valve body 5 through the valve rod groove and is connected with the valve core, the valve rod 6 can rotate in the valve rod groove, and the valve core can be driven to rotate by rotating the valve rod 6. The handle is connected to the one end of wearing out valve body 5 with valve rod 6, rotates the handle and can drive valve rod 6 and rotate, and it is more convenient to operate.
