It is a, 24. magnetic core sealing drums, 25. lock screws.
Specific embodiment
It sets: as 35 DEG C when environment temperature reaches the transformation temperature of memory alloy spring.
After assembling spray fire valve of the present invention at normal temperature, the handle (9) are rotated, drive the biasing bullet
Spring adjustment cap (18) lower movement in same direction, presses to the bias spring adjustment cap (18), make the magnet ring set (12) to
Lower movement makes the core assembly that the stifled pad (6) of the relief hole be driven to block the relief hole (2) and diaphragm support downwards
(19), until valve is water-tight under normal conditions, move down it at this point, rotating the handle positioning cap (17), described in locking
Handle (9) it is motionless, moved down at this point, the switch control bucket (21) is synchronized in company with the magnet ring set (12), make the temperature control
Spring (16) is in pressured state, meanwhile, the anti-clogging spring (5) also moves down and is in pressured state, and bias spring (20)
In slave mode.
When the environment temperature of temperature control spring (16) local environment reaches transformation temperature, the temperature control spring (16) is extensive
Multiple memory, is elongated to reset condition, switch control bucket (21) described in generated outburst power drive moves up, and drives the magnetic suddenly
Ring set (12) moves up, and the stifled pad (6) of the relief hole, which is also servo-actuated, to be moved up, and opens valve, makes shower water from the valve body (1) left side
Water inlet flows into, and after the entering pressure hole (3), is downwardly towards going out on the right of the valve body (1) from the relief hole (2)
The mouth of a river, once environment temperature just returns to normal less than 35 DEG C.If at this point, due to the material of the temperature control spring (16), aging
Or part is loosened due to mismachining tolerance, when valve being caused to close not tight and leak, needs to back-out lock screw (25) again again
Rotating handle (9) as described above adjusts the precompression for giving the bias spring adjustment cap (18) again, until valve is water-tight
Until, if be not easy to be restored to origin-location after finding the diaphragm (4) elasticity variation, need to reversely rotate the rotating handle
(9), to reduce the pressure that the stifled pad (6) of the relief hole imposes on the diaphragm (4) under normal conditions, position is moved up, directly
Until the original state for restoring the diaphragm (4).
