Abstract
FIELD: mechanical engineering; protection of systems against excessive pressure. SUBSTANCE: connected to housing 1 is breakable rod 6 with weakened section 7 whose head 9 is engageable with bush 10 of rod 4 taking up action of working medium through bellows 5 located coaxially relative to rod 4. Rod is rigidly connected with sleeve 11 on whose rim spring 2 rests through separator 14. In case of rise of pressure of working medium, rod 4 moves making cylindrical members 13 shaft radially and enter bore 16 of housing; in this case, compressive force of spring closes to housing and rod 4 is acted on by entire force of bellows 5. Bush 10 of rod catches head 9 of breakable rod 6 which is broken in weakened section 7 at rated pressure. After relieving the pressure, rod 4 moves towards breakable rod under action of compressive force of bellows 5 and cylindrical members 13 escape from bore 16 and again rest on head of sleeve 11. For replacement of breakable rod 6, disconnect it from housing, withdraw head 9 and insert new rod 6 having connected it with housing. EFFECT: enhanced reliability of valve operation since there is no need to disassemble its components for replacement of breakable rod. 3 dwg
