Detailed Description
In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.
As shown in fig. 1-4, a compact valve core is provided, which comprises a valve rod 1, and a stop collar 2 and a valve core sleeve 3 which are sequentially sleeved outside the valve rod 1, wherein the valve rod 1, the stop collar 2 and the valve core sleeve 3 are tightly attached to each other two by two during sleeving, and the inner surface of the stop collar 2 is smoothly matched with the outer surface of the valve rod 1. The limiting sleeve 2 and the valve core sleeve 3 are fixedly connected, namely, the limiting sleeve and the valve core sleeve cannot rotate relatively, the side surfaces of the limiting sleeve and the valve core sleeve are respectively provided with a first water outlet 21 and a second water outlet 31 which are communicated along the radial direction, the first water outlet 21 and the second water outlet 31 are arranged in a superposition mode to realize communication, in the concrete manufacturing process, one or two water outlets are arranged on the first water outlet 21 and the second water outlet 31, and the two first water outlets 21 or the two second water outlets 31 are arranged oppositely. The valve rod 1 is connected with the limiting sleeve 2 in a rotating mode, specifically, the inner side face of the limiting sleeve 2 and the outer side face of the valve rod 1 are smooth faces, and smooth matching is beneficial to relative rotation of the limiting sleeve 2 and the valve rod. And the valve rod 1 is provided with a third outlet hole 11 which can be communicated with the first outlet hole 21 and the second outlet hole 31, and when the third outlet hole 11 is overlapped with the first outlet hole 21 and the second outlet hole 31, the third outlet hole 11 is communicated with the first outlet hole 21 and the second outlet hole 31. The valve rod 1 is of a hollow structure, a water inlet hole 14 communicated with the third water outlet hole 11 is formed in the lower end of the valve rod 1, and the valve core is switched between an opening state and a closing state by rotating the valve rod 1.
Thus, when the valve core is in an open state, the valve rod 1 is rotated to enable the three water outlet holes to be superposed and communicated, and water enters the valve rod 1 from the water inlet hole 14 and then flows out of the water outlet holes; when the case was closed, rotated valve rod 1 for third apopore 11 staggers the setting with first apopore 21 and second apopore 31, and water is blockked by 1 pole wall of valve rod, consequently can't follow third apopore 11 and flow out, thereby can't realize out water. Compared with the prior art, the operation of boiling water and shutting off water just can be realized to the ingenious cooperation of three part of present case, and overall structure is compacter and exquisite to not only practiced thrift manufacturing cost, reduced the equipment degree of difficulty moreover.
Preferably, the lower end of the valve rod 1 forms an arc-shaped limiting part 12, and the inner surface of the lower end of the limiting sleeve 2 is matched with the arc-shaped limiting part 12 to form a limiting block 22. Spacing portion 12 of arc and stopper 22 mutually support and can play restriction valve rod 1 degree of rotation, in this embodiment, as shown in fig. 2, the case is in the closed condition, and the spacing convex part one end of arc supports one of them end of stopper 22 this moment, and when will opening the case, anticlockwise rotation valve rod 1, until the spacing portion 12 other end of arc supports the stopper 22 other end, can realize that third apopore 11 aims at first apopore 21 of intercommunication and second apopore 31. The whole operation process is simple and quick.
As a fixed connection mode of the valve core sleeve 3 and the position limiting sleeve 2, a first toothed positioning part 32 is annularly arranged on the inner surface of the lower end of the valve core sleeve 3, a second toothed positioning part 23 is arranged on the outer surface of the lower end of the position limiting sleeve 2, and the first toothed positioning part 32 and the second toothed positioning part 23 are meshed with each other, so that the position limiting sleeve 2 cannot rotate relative to the valve core sleeve 3.
Preferably, the limiting sleeve 2 is integrally formed by plastic through injection molding, and the valve rod 1 and the valve core sleeve 3 are made of copper or stainless steel or other metal materials. In actual production, valve rod 1 and case cover 3 are moulded earlier, then put into the mould of injection molding machine together with valve rod 1 and case cover 3 in, then toward injection moulding play stop collar 2 between valve rod 1 and the case cover 3, just so accomplished the preparation of whole case main part, can not only ensure that stop collar 2 is accurate to be inlayed and establish between valve rod 1 and case cover 3, can avoid too much equipment work moreover, reach the effect that high-efficient high quality was made.
Preferably, the outer surface of the valve rod 1 is provided with first limiting rings 13 above and below the third water outlet hole 11, so that the valve rod 1 is prevented from moving up and down in the limiting sleeve 2; the bottom of the limiting sleeve is provided with a first sealing ring 24, the outer surface of the valve core sleeve 3 is provided with a second sealing ring 33, the valve core sleeve 3 is in threaded connection with the water valve shell, and the second sealing ring 33 effectively prevents water leakage of the water valve.
The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications made by those skilled in the art should not be construed as departing from the scope of the present invention.
