Abstract
The utility model discloses an elbow valve for farm irrigation. The elbow valve comprises a valve body, wherein a water-inlet cavity of the valve body is vertical to the central line of a water-outlet cavity of the valve body; a spiral valve stem hermetically connected with the valve body in a threading way is positioned on the central line of the water-inlet cavity; the bottom of the spiral valve stem is connected with a disc type valve core; the water-inlet cavity is connected with a rotatable connecting pipe through a flange; an annular groove of which the outer diameter is equal to or smaller than the inner diameter of the water-inlet cavity is formed in the inner side of the upper end of a lower flange disc; a clamping ring matched with the annular groove is arranged on the periphery of the upper end of the rotatable connecting pipe; an annular sealing surface is arranged on the upper end surface of the clamping ring; the annular sealing surface and the upper end surface of the lower flange disc are positioned on the same plane; an annular sealing cushion is arranged between an upper flange disc and the lower flange disc; the inner diameter of the annular sealing cushion is not greater than that of the annular sealing surface of the clamping ring. The elbow valve has the characteristics of low manufacturing and mounting cost, long service life, low maintenance cost and the like.
Description
Technical field
The utility model relates to a kind of field irrigation bending head type valve.
Background technique
The water spray elbow of the valve that field irrigation is at present used and valve top is split type, need to install and could use through combination, installation cost is higher, also easily occurs installation quality problem simultaneously, and valve generally adopts butterfly valve, grown service time afterwards because poor sealing phenomenon easily appears in wear reason, thereby cause leaking, shortened working life, increased maintenance cost, because valve is split type with water spray elbow, increased raw-material consumption in working process simultaneously.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of field irrigation bending head type valve, and it has the features such as make and installation cost is low, long service life, maintenance cost are low.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
Comprise the valve body that water-inlet cavity and water chamber center line are perpendicular, the spiral valve rod being tightly connected with valve body screw thread is positioned on the center line of water-inlet cavity, the bottom of spiral valve rod is connected with disc type spool, water-inlet cavity be rotatably connected pipe flange and be connected: in inner side, lower flange upper end, be provided with the annular groove that external diameter is equal to or less than water-inlet cavity internal diameter, be rotatably connected pipe upper end periphery and be provided with the snap ring suitable with annular groove, snap ring upper-end surface is provided with lower flange upper-end surface and is positioned at conplane annular sealing surface, between upper flange plate and lower flange, be provided with Gask-O-Seal, Gask-O-Seal internal diameter is not more than the annular sealing surface internal diameter of snap ring.
The utility model further improves and is:
Lower flange bottom connects guide pipe, is rotatably connected pipe and is positioned at guide pipe, and be slidably matched with guide pipe.
Valve body, upper flange plate, lower flange, be rotatably connected pipe and guide pipe be PVC＝polyvinyl chloride material.
Gask-O-Seal is annular rubber cushion.
The beneficial effect that adopts technique scheme to produce is:
Comprise the valve body that water-inlet cavity and water chamber center line are perpendicular, make it to have the combination function of valve and water spray elbow, for level sprinkling irrigation, than the mode of early gate and the installation of water spray bend-head combination, save material and mounting cost, improved the reliability of product; In inner side, lower flange upper end, be provided with the annular groove that external diameter is equal to or less than water-inlet cavity internal diameter, be rotatably connected pipe upper end periphery and be provided with the snap ring suitable with annular groove, can make to be rotatably connected rotate relative with valve body of pipe, the change to water spraying direction while irrigating to complete; Snap ring upper-end surface is provided with lower flange upper-end surface and is positioned at conplane annular sealing surface, between upper flange plate and lower flange, be provided with Gask-O-Seal, Gask-O-Seal internal diameter is not more than the annular sealing surface internal diameter of snap ring, to complete pipeline water route inner chamber and outside sealing, spiral valve rod makes disc type spool and Gask-O-Seal valve seat form sealing pair by rotating down pressing, sealability butterfly valve is before reliable, long service life, therefore, it has the features such as make and installation cost is low, long service life, maintenance cost are low.
