1. Field of the Invention
The present invention relates generally to a ceramic valve, and more particularly to an innovative design of an anti-pressure ceramic valve.
2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 37 CFR 1.98
The structure of a conventional ceramic valve 10 is as disclosed in
There is one point to be additionally mentioned: in actual manufacturing of water tap products, the assembly of the whole water tap structure and the production of the ceramic valve are usually conducted in different factories. Therefore, it is very difficult to solve the above-mentioned problem in the downstream water tap assembly factory (because it is hard to control uniform locking pressure of the nut). This problem must be solved by the upstream ceramic valve manufacturer. Hence, it is an important technical challenge for the related manufacturers to find a solution to improve the structure of the conventional ceramic valve and solve the above-mentioned problem.
Thus, to overcome the aforementioned problems of the prior art, it would be an advancement if the art to provide an improved structure that can significantly improve the efficacy.
Therefore, the inventor has provided the present invention of practicability after deliberate design and evaluation based on years of experience in the production, development and design of related products.
The “anti-pressure ceramic valve” disclosed by the present invention is technically characterized by the unique design and constitution of the valve casing, positioning slots, combination-type top base, positioning snaps, water-controlling component, base, anti-pressure gap, and sinking ring surface, so that the present invention provides an advancement over the existing structure of the “prior art”: when the ceramic valve is installed in an existing water tap valve spool, the pressure from the tightening nut will be received only by the upper opening of the valve casing, not by the combination-type top base, so that the preset accuracy of the assembly of the driving base, turning valve plate, and fixing valve plate of the water-controlling component will not be affected. In this way, the water-controlling component will maintain its preset accuracy and operational quality after installation of the ceramic valve. Hence, the present invention is practically advanced and has a good value for industrial utilization.
Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
Said ceramic valve A comprises a valve casing 30, made of plastic material and being a hollow cylinder, including an upper opening 31, a lower opening 32 and a holding space 33 between the upper and lower openings 31, 32.
At least two positioning slots 34, being a crosswise through-hole, are configured at a position on the valve casing 30 near the upper opening 31.
A combination-type top base 40, made of plastic material, is fixed on the upper opening 31 of the valve casing 30. The combination-type top base 40 forms a flanged tube portion 42 extending upward from the center of the flange 41.
At least two positioning snaps 43 are raised from the periphery of the flange 41 of the combination-type top base 40, to match and fix with the positioning slots 34 on the valve casing 30.
A water-controlling component 50 is housed inside the holding space 33 of the valve casing 30, including a driving base 51, a valve stem 52, a turning valve plate 53, and a fixing valve plate 54, wherein the driving base 51 is configured inside the flanged tube portion 42 of the combination-type top base 40 in a rotating state, the valve stem 52 is pivotally fixed on the driving base 51 through a cross shaft 55 and can swing vertically. Moreover, the top end of the valve stem 52 has a receiving section 521 extending upward from the driving base 51. The turning valve plate 53 is installed below the driving base 51 and can be driven to move by the bottom end of the valve stem 52, and the turning valve plate 53 is next to the fixing valve plate 54 on the upper side.
A base 60 is fixed onto the lower opening 32 of the valve casing 30, to limit the assembly of the water-controlling component 50.
An anti-pressure gap 70 is formed between the positioning snaps 43 and the top wall of the positioning slot 34.
A sinking ring surface 44 is formed on the top surface of the flange 41 of the combination-type top base 40. The sinking ring surface 44 has a sinking distance relative to the upper opening 31 of the valve casing 30 (marked by H1 in
The above-described structure constitutes the design of the present invention. Referring to
