  • the spool has the ability to rotate around the axis, as well as slightly change the angle relative to the vertical axis to ensure a snug fit to the seat. Since a flange 18 is made along the edge of the bypass hole 4 in contact with the sealing element 10, the reliability of closing the valve inlet channel is increased.
  • the locking mechanism is rotated using the flywheel 7.
  • the screw spindle 6, interacting with the internal thread of the sleeve 17 is moved up together with the spool.
  • the bypass hole 4 is opened and water from the system enters the internal cavity of the valve and then through the outlet nipple 3 into the fire hose.
  • the water flow rate is set by the height of the spindle 6.
  • the internal cavity of the upper part of the cover AND is made with the possibility of providing an increased stroke of the screw spindle 6 due to the presence of free space 16 for the thread to exit when the valve is opened, the spool rises to the maximum possible height (unlike from known valves). This allowed to reduce the dimensions of the valve body - both the height H and the outer diameter D.

Abstract

La vanne comprend un corps avec des tubulures d'entrée et de sortie), qui communiquent par l'intermédiaire de l'orifice de transfert dans un siège, et un mécanisme de coupure situé à l'intérieur du corps ayant la forme d'une tige filetée avec un volant monté sur une extrémité et une soupape à tiroir fixée à l'autre extrémité, la soupape à tiroir étant constituée d'un élément métallique en forme de disque et d'un élément d'étanchéité élastique qui obture l'orifice de transfert lorsque la vanne est en position fermée, ainsi qu'un couvercle ayant la forme d'une bride avec un trou traversant central et avec une douille comportant un autre élément d'étanchéité, qui sont situés dans la partie supérieure du couvercle, ladite partie supérieure étant constituée de saillies hexaédrique et cylindrique. Les axes de la tubulure d'entrée et de la tubulure de sortie sont orientés à un angle α = 90° - 130°. Le rapport de la hauteur h du corps au diamètre extérieur du corps satisfait la condition Н/D = 0,85 - 1,25, la cavité interne de la partie supérieure du couvercle ayant été réalisée de manière à permettre une course plus longue de la tige filetée lors de l'ouverture de la vanne. La conception de la vanne permet de réduire les dimensions et le poids.
