CLOSING HOSE VALVE Russian patent published in 2018 - IPC F16K7/07 F16K7/04 

FIELD: valves production.

SUBSTANCE: invention relates to stop valves. Closing hose valve comprises additional diaphragm located between the elastic hose and body lower cover with the closed volume formation between the additional diaphragm and the body lower cover, additional device for the ambient air supply to the closed volume between the additional diaphragm and the body lower cover, attached to the additional diaphragm pressing element. In the cross-section both pressing elements have triangular shape and mounted on the diaphragms symmetrically opposite to each other so, that the pressing elements cross-section triangles bases are mated to the corresponding diaphragms surface, and the cross-section triangles vertices rest against the elastic hose opposite walls. As the diaphragms motion actuator, the driving air-gas medium is used, which enters the closed volumes between the body covers and the diaphragms from the main line through the driving air-gas medium supply devices. Closed volume between the elastic sleeve outer walls and the diaphragms is connected to the driving air-gas medium mainline by means of tube.

EFFECT: air supply devices and driving air-and-gas medium include corresponding pipelines with controlled by sensors taps.
