Description
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of ball valve that is entirely welded and fixed.
Background technique
At present, at electric power, waterpower, petrochemical industry, on the pipeline of metallurgy industry, all can use fixing ball valve, cut-out for liquid in pipeline, the structure of existing fixing ball valve comprises: valve body, be arranged on left valve gap and the right valve gap and the Stuffing box that is arranged on valve body upper end of the left and right sides of valve body, described valve body and left valve gap, it between right valve gap and Stuffing box, is split-type structural, at described valve inner, be arranged on spheroid and seat ring, at valve body, left valve gap, in right valve gap and seat ring, be respectively provided with runner, described spheroid is connected with the lower end of valve rod, the upper end of described valve rod is connected with valve rod driving device.Existing fixing ball valve, unreasonable structure, sealing effect is bad, and medium easily leaks outside, and can not realize fast opening and closing.
Model utility content
Technical problem to be solved in the utility model is: what a kind of good sealing effect was provided is welded and fixed ball valve entirely.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: be entirely welded and fixed ball valve, comprise: valve body, be arranged on left valve gap and the right valve gap and the Stuffing box that is arranged on valve body upper end of the left and right sides of valve body, described valve body and left valve gap, between right valve gap and Stuffing box, be all welded to connect, at described valve inner, be arranged on spheroid and seat ring, at valve body, left valve gap, in right valve gap and seat ring, be respectively provided with runner, described spheroid is connected with the lower end of valve rod, the upper end of described valve rod is connected with valve rod driving device, the triangular sealing ring that is provided with preloading spring and cooperatively interacts with spheroid at described seat ring, the place, three angles of described triangular sealing ring is arc shaped surface, on described spheroid, be provided with Decompression valves.
In order to solve the problems of the technologies described above better, the further technological scheme that the utility model adopts is: the lower end of described Stuffing box is provided with four and opens snap ring.
The utility model has the advantages that: the above-mentioned ball valve that is entirely welded and fixed, rational in infrastructure, easy to operate, good seal performance, medium, without leaking outside, can be realized fast opening and closing.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model is welded and fixed ball valve entirely.
In figure: 1, valve body, 2, left valve gap, 3, right valve gap, 4, Stuffing box, 5, spheroid, 6, seat ring, 7, valve rod, 8, preloading spring, 9, triangular sealing ring, 10, Decompression valves, 11, four open snap ring.
Embodiment
Below in conjunction with the drawings and specific embodiments, describe in detail particular content of the present utility model.
As shown in Figure 1, entirely be welded and fixed ball valve, comprise: valve body 1, be arranged on left valve gap 2 and the right valve gap 3 and the Stuffing box 4 that is arranged on valve body 1 upper end of the left and right sides of valve body 1, described valve body 1 and left valve gap 2, between right valve gap 3 and Stuffing box 4, be all welded to connect, in described valve body 1 inside, be arranged on spheroid 5 and seat ring 6, at valve body 1, left valve gap 2, in right valve gap 3 and seat ring 6, be respectively provided with runner, described spheroid 5 is connected with the lower end of valve rod 7, the upper end of described valve rod 7 is connected with valve rod driving device, the triangular sealing ring 9 that is provided with preloading spring 8 and cooperatively interacts with spheroid 5 at described seat ring 6, the place, three angles of described triangular sealing ring 9 is arc shaped surface, on described spheroid 5, be provided with Decompression valves 10.
The above-mentioned ball valve that is entirely welded and fixed, drives spheroids 5 to rotate around axis by valve rod driving device actuate valve stem 7, when spheroid 5 runners and valve body 1, left valve gap 2 and right valve gap 3 runners are when perpendicular, and valve closing.When spheroid 5 runners are connected with right valve gap 3 runners with valve body 1, left valve gap 2, valve opening.
In the present embodiment, the lower end of described Stuffing box 4 is provided with four and opens snap ring 11, plays well fixing and sealing effect.
Between described valve body 1 and left valve gap 2, right valve gap 3 and Stuffing box 4, be all welded to connect, can effectively prevent that medium from leaking outside, rational in infrastructure.
The place, three angles of described triangular sealing ring 9 is arc shaped surface, and material adopts AED, the temperature that ability is 200 ℃, and sealing surface and spheroid 5 contact position employing line surface of contact, good sealing effect.
During valve opening, preloading spring 8 pretension seat rings 6 and spheroid 5, be close to triangular sealing ring 9 and spheroid 5 surfaces, two way sealed, and the lumen of spheroid 5 is by Decompression valves 10 releasing pressure automaticallies.Equally, during valve closing, two sides have pressure medium to do the used time, and both sides seat ring 6 is pushed respectively spheroid 5 both sides to, can realize two way sealed.
