Title: Pressure relief valve (embodiments) and valve assembly containing said valve
Inventor: VULKAN OMER
IPC: F16K17/04
Filed: 2015-11-04
Granted: 2019-10-07
Abstract: FIELD: machine building. 
     SUBSTANCE: invention relates generally to pressure relief valves, in particular, to pressure release valves for steam fuel systems. Pressure release valve (10) is designed to control the fluid flow between the first fluid passage (12a) and the second fluid passage (12b). Pressure relief valve comprises housing (14), diaphragm element (24) movably fixed inside housing and having hole (18) for fluid medium, first deflecting element (20) for forced movement of diaphragm element in first direction and sealing element (26) movably installed in housing and made with possibility of reversible sealing of hole (18) for fluid medium. When pressure in second fluid passage (12b) exceeds first predetermined threshold value, diaphragm element (24) is pressed to first diverting element (20), and sealing element (26) is first forced to move to fluid medium opening (18) and then comes out of contact with fluid medium opening, providing fluid communication between the second fluid passageway (12b) and the first fluid passageway (12a) by means of a fluid hole. When pressure in second channel (12b) for fluid medium decreases below second predetermined threshold value, sealing element (26) comes out of contact with diaphragm element (24), providing fluid communication between the first fluid passage and the second fluid passage by means of a fluid port. Also provided is a valve assembly comprising a pressure release valve (10) and valve (60) driven from outside. 
     EFFECT: technical result is elimination of insufficient pressure, as well as delay of valve release at excess pressure, wherein each of these actions begins from initial closed position, wherein as soon as the sealing element stops interacting with the diaphragm element under insufficient pressure conditions, this allows the fluid medium to flow from the first hole to the second hole through the fluid medium hole.
