Abstract
The utility model is two-purpose valve. Two ends of the liquid path of the valve body {11} is provided with an inserting inner cavity {12} without a flange tube; the inner wall of a port is provided with a conical groove {2}; a sealing ring {7} is arranged inside of the groove. A flange {9} and a sealing ring {7} are covered on a PVC without a flange tube {8} etc. The tube {8} is inserted in the cavity {12}; the flange {9} is connected with the flange {1} equipped on the valve; the sealing ring {7} is pressed into the conical groove {2} for being sealed; the valve can still be connected with a casting iron flange tube through the flange on the valve body, which is convenient and rapid for assembly and disassembly, of simple structure and easy processing.
Description
Technical field the utility model relates to the valve by the flange connections road.
Background technique has been widely used in water supply pipe at present because plastic tube low prices such as PVC do not have secondary pollution.And the present general valve that is connected with the cast iron flange pipe, be connected but relatively difficulty with plastic pipe such as PVC, normally stick with glue a PVC flange (its price is 3-5 a times of iron flange) at pvc pipe pipeline joint place, be connected with valve by this flange again, uneven slightly, will breaking or come unstuck in the gluing place of PVC flange and pvc pipe, have only when this phenomenon occurring pvc pipe is dismissed one section, and original PVC flange is also scrapped and can not be used.
Summary of the invention the utility model proposes a kind of Two purpose valve in order to solve the problem that is connected inconvenience of plastic tubes such as above-mentioned PVC and valve, both can be connected with flanged (FLGD) pipeline, can be connected quickly and easily with plastic tube such as flanged (FLGD) PVC not again.
A kind of Two purpose valve of the utility model, the two ends, fluid passage of its valve body have can insert can't blue pipe inner chamber, its port outer wall is provided with connecting flange; Have cone tank on the inwall of port, seal ring is housed in the groove.During connection, cover upper flange and seal ring on PVC etc. can't blue pipe insert pipe in the fluid passage inner chamber of valve body, and loose flange is connected with fastening flange on the valve, by loose flange seal ring is squeezed in the cone tank, make between valve body port and the pipe to seal.Owing to have flange on the valve body, thereby still can be connected with the cast iron flange pipe.
The utility model is owing to adopt flange crush seal circle to come directly fastening and sealing pvc pipe etc. can't blue pipeline, only need during connection pipe is inserted in the fluid passage of valve, tightening flange gets final product, not only charge and discharge operations is very convenient quick, safe and reliable, is convenient to maintenance, and loose flange cylinder iron flange get final product, not only economical with materials but also reduced cost was simple in structure, easily processing.
Description of drawings Fig. 1 is the utility model structural representation.
Embodiment is by shown in Figure 1, this Two purpose valve is made up of valve body [11], flashboard [3], valve rod [4], valve gap [5] and handwheel [6], the two ends, fluid passage of valve body [11] are provided with connecting flange [1], have screw on the flange, the two ends, fluid passage have can insert can't blue pipe inner chamber [12], have trumpet-shaped cone tank [2] on the port inner wall, end face is housed in the groove is trapezoidal seal ring [7].Can directly be connected with the cast iron flange pipe by the flange on the valve body [1].
When can't blue pipeline being connected with PVC etc., shown in dotted line position among the figure, on pipeline [8], put earlier loose flange [9] and seal ring [7], pipeline [8] is inserted in the fluid passage inner chamber [12] of valve body, loose flange [9] is connected by bolt [10] with fastening flange [1] on the valve, by loose flange [9] seal ring [7] is squeezed in the cone tank [2], make between valve body port and the pipeline to seal.
Claims (2)
