Abstract
The utility model relates to a valve. The valve comprises a valve body, a valve cover and a valve plate. The inner wall and the outer wall of the valve body are respectively provided with a ceramic layer; the inner wall and the outer wall of the valve cover are respectively provided with a ceramic layer; and the outer wall of the valve plate is provided with a ceramic layer. According to the valve, the inner wall and the outer wall of the valve body are respectively provided with the ceramic layer, the inner wall and the outer wall of the valve cover are respectively provided with the ceramic layer, the outer wall of the valve plate is provided with the ceramic layer, therefore corrosion resistance, abrasion resistance and high temperature resistance of the valve are improved, and the service life of the valve is prolonged.
Description
Technical field
The utility model relates to a kind of valve.
Background technique
Valve is the controlling component in the fluid delivery system, have by, adjusting, water conservancy diversion, prevent functions such as adverse current, voltage stabilizing, shunting or overflow pressure release.The valve that is used for liquid control system, from the simplest stop valve to very complicated robot control system(RCS) used various valves, its kind and specification are quite various.Valve can be used for controlling flowing of all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.
Valve is the important control device that promotes the device development of modern transportation water, gas, stream material, in daily use, need it to have certain corrosion resistance, high temperature resistance and wear resistance, in the prior art, one deck epoxy resin is set or paint prevents that it from contacting extraneous water and air in valve surface often, in order to avoid damages of getting rusty, does not still improve the corrosion resistance and the high temperature resistance of valve, with and wear resistance, and the life-span is shorter.
The model utility content
In view of this, be necessary the valve that provides a kind of corrosion resistance, wear resistance, high temperature resistant property, working life all to improve.
The utility model is achieved in that a kind of valve, comprises valve body, valve gap, valve plate, and the inner and outer wall of described valve body all is provided with one deck ceramic layer.
Further, the inner and outer wall of described valve gap all is provided with one deck ceramic layer.
Further, the outer wall of described valve plate is provided with one deck ceramic layer.
The advantage of the valve that the utility model provides is: by the inner and outer wall at described valve body one deck ceramic layer is set all; The inner and outer wall of described valve gap all is provided with one deck ceramic layer; The outer wall of described valve plate is provided with one deck ceramic layer, improves corrosion resistance, wear resistance, the high temperature resistant property of valve, prolongs the working life of valve.
Description of drawings
Fig. 1 is an existing valve mechanism schematic representation described in the prior art;
Fig. 2 is the structural representation of the utility model valve.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
See also Fig. 1, Fig. 1 is an existing valve mechanism schematic representation described in the prior art.
Existing valve comprises valve body 1, valve gap 2, valve plate 3, valve rod 4, valve plate seal ring 5, gland 6, handwheel 7 and valve seals 8.The inside of valve body 1 is provided with bigger cavity, and there is unlimited opening at two ends, is convenient to entering and flowing out of fluid like this.Valve gap 2 is installed in the top of valve body 1, and valve gap 2 inside are provided with certain cavity, and the cavity of this cavity and valve body 1 inside mates mutually.Be provided with valve seals 8 between valve gap 2 and the valve body 1,, utilize the locking nut (not shown) that the three tightly is locked together in case fluid is revealed.The oral area of valve gap 2 upper ends is less, and the oral area inboard is provided with internal thread.
Bigger cavity central position at valve body 1 is equipped with valve plate 3, between the both sides of valve plate 3 and the valve body 1 valve plate seal ring 5 is installed, and valve plate 3 is flat tabular, and its size is bigger slightly than the cavity in the valve body 1, just in time can stop fluid to flow in valve body 1.Valve rod 4 is installed directly over the valve plate 3, and valve rod 4 is provided with outside thread.Valve rod 4 passes the oral area of valve gap 2 upper ends, and the internal thread of outside thread on the valve rod 4 and valve gap 2 oral areas is meshing with each other.
Be provided with gland 6 in valve gap 2 upper ends, gland 6 neutral positions are provided with center hole, gland 6 and valve gap 2 screw-threaded couplings.Gland 6 upper ends are provided with handwheel 7, and handwheel 7 centers are provided with elongated center-pole 7a, and center-pole 7a passes the center hole of gland 6, are connected and fixed with valve rod 4.
When rotation hand wheel 7, center-pole 7a drives valve rod 4 rotations, and under valve gap 2 oral area screw-thread fit, valve rod 4 rotations also move up and down, and drive moving up and down of valve plate 3 by moving up and down of valve rod 4 like this, finally realize the open and close of valve.
See also Fig. 2, Fig. 2 is the structural representation of the utility model valve.
Valve described in the utility model is to improve on existing valve mechanism basis, and it improves component and comprises: valve body 1 ', valve gap 2 ', valve plate 3 '.
Described valve comprises valve body 1 ', valve gap 2 ', valve plate 3 ', it is characterized in that, the inner and outer wall of described valve body 1 ' all is provided with one deck ceramic layer 9; The inner and outer wall of described valve gap 2 ' all is provided with one deck ceramic layer 9; The outer wall of described valve plate 3 ' is provided with one deck ceramic layer 9.
By inner and outer wall one deck ceramic layer 9 is set all at described valve body 1 '; The inner and outer wall of described valve gap 2 ' all is provided with one deck ceramic layer 9; The outer wall of described valve plate 3 ' is provided with one deck ceramic layer 9, improves corrosion resistance, wear resistance, the high temperature resistant property of valve, prolongs the working life of valve.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
