Definitions

  • the present disclosure relates to fire protection systems and, more particularly, to a trim manifold assembly that controls the operation of the control valve of a sprinkler system for various fire protection systems.
  • Fire protection systems come in several forms. For example, deluge fire protection systems totally flood the protected area with pressurized fire suppressant, such as water by way of non-limiting example, with the system designed to empty until the control valve is closed by a release system, such as a hydraulic, pneumatic, electric, or manual release system. These deluge systems are often used in an area in which a fire may spread rapidly or in an area that contains combustible material, solutions, or the like. Other fire protection systems cycle between an actuated and non-actuated state and, in some cases, only deliver water to the effected area when activated by a heat sensor.

Additionally, the complexity of the trim piping may result in installation errors that can impair proper operation. Moreover, the trim piping can be cumbersome in size and weight such that use in tight spaces is inhibited and/or prohibited.
  • a trim manifold assembly is utilized to facilitate control of the control valve in a fire protection system.
  • the trim manifold assembly utilizes a manifold block with numerous passageways to provide desired flow communication between various components, such as automatic and manual valves, check valves, inlet and outlet ports, and sensor ports, by way of non- limiting example.

  • Trim manifold assembly 22 may be manually operated as opposed to automatic actuation, discussed above.
  • the manual operation varies from the automatic operation only in the terms of the initiation of the operation.
  • the operator opens emergency relief valve assembly 104, which reduces the fire suppressant pressure from prime input passage 62 and prime-line output passage 84.

  • Trim manifold assembly 22 allows for the pressure alarms coupled to first and second alarm passages 136, 138 to be tested without activating valve 24.
  • Alarm test valve assembly 66 can be opened, which results in fire suppressant in prime input passage 62 flowing past seat seal 66a and into alarm test valve passage 64. The fire suppressant will then enter drain check valve assembly 126 between seat seal 126a and stem seal 126b. This traps the pressure in this chamber and thus prevents the operation of PORV 108.
  • the fire suppressant travels through drain check valve assembly 126 to first and second alarm passages 136, 138.

  • Check valve assembly 80 in prime-line check valve passage 78 can protect the prime pressure in priming chamber 46 of valve 24 from being reduced as a result of varying supply pressures of the fire suppressant and/or operation of alarm test valve assembly 66.
  • prime-line check valve assembly 80 lets the fire suppressant go past seat seal 80a as the pressure overcomes the force of the biasing spring 80d.
  • spring 80d causes seat seal 80a to close and, as a result, retain the pressure in prime-line check valve passage 78.
  • prime-line check valve assembly 80 protects the pressure in priming chamber 46 of valve 24 from being subjected to varying pressures as a result of potentially varying supply pressure of the fire suppressant. Additionally, this also protects priming chamber 46 from being subjected to varying pressures as a result of operation of alarm test valve assembly 66.
  • Drain check valve assembly 126 is configured to allow the pressure in first and second alarm passages 136, 138 to be drained through PORV passage 106 while not causing the operation of PORV 108.
  • alarm test valve assembly 66 when alarm test valve assembly 66 is opened, fire suppressant from prime input passage 62 flows through manifold 60 to the port between seat seal 126a and stem seal 126b.
  • the fire suppressant pressure is checked from PORV sensing port 108c by drain check valve assembly 126 which is a drip check valve.
  • Drain port (orifice) 126c of drain check valve assembly 1 26 is sized such that it is sufficient to drain the pressure from first and second alarm passages 136, 138 through PORV passage 106 while not causing the operation of PORV 108.
  • Drain check valve assembly 126 allows the fire suppressant to flow into first and second alarm passages 136, 138 at a first flow rate while also allowing fire suppressant to flow out of first and second alarm passages 136, 138 through drain port 126c at a second flow rate substantially less than the first flow rate. This prevents operation of PORV 108 and thus operation of fire protection system 20 when testing the pressure alarms.
