FIELD: machine engineering.
SUBSTANCE: device comprises a body 6 with a flange 9, a flip cover 7, a detachable opening and closing unit 8 of the flip cover 7. The body 6 is made in the form of a cross piping connection. The flip cover 7 is formed as a convex elliptical bottom with a sealing element, is located in the cavity 45 of the body 6, is provided with a perforated sector 26, a pivotable perforated sector 29 and a bracket with a roller slider 31. The perforated sector 26 is rigidly attached to the elliptical bottom. The roller slider 31 cooperates with a guide 11 rigidly attached to the body 6.
EFFECT: simplifying the design, ensuring the start and reception of the flow projectile into the control device during the process of checking fluid flow measurement means with a unidirectional pipe-piston verification installation in tight conditions, simplifying the maintenance of the installation.
