Embodiment Construction

[0013] Setting: when the ambient temperature reaches the transformation temperature of the memory alloy spring, it is 35°C.

[0014] After the sprinkler fire valve of the present invention is assembled at normal temperature, the handle (9) is rotated to drive the bias spring adjustment cap (18) to move down in the same direction, giving the bias spring adjustment cap ( 18) Apply pressure to move the magnetic ring sleeve (12) downward, so that the magnetic core assembly drives the pressure relief hole plugging pad (6) to block the pressure relief hole (2) and diaphragm downward Bracket (19), until the valve does not leak under normal conditions, at this time, rotate the handle positioning cap (17) to move down, lock the handle (9) and do not move, at this time, the switch controls the barrel (21) move down synchronously with the magnetic ring sleeve (12), so that the temperature control spring (16) is in a compressed state, and at the same time, the anti-blocking spring (5) als...

Abstract

The invention relates to a temperature-controlled spraying fire valve capable of compensating the memory alloy spring deformation error, and belongs to the technical field of spraying fire valves with controllable assembling errors and based on memory alloy springs. The temperature-controlled spraying fire valve comprises a temperature control part, a valve switch part, an error compensation part and a spraying fire-fighting part. In a normal state, a handle of the error compensation part adjusts the valve through a bias spring adjustment cap, pre-pressure of a bias spring in the valve switch part enables a pressure relief port blocking pad in a magnetic execution assembly to close the valve exactly, the valve is water-tight, meanwhile a memory alloy spring in the temperature control part is pressed, when the ambient temperature reaches the memory alloy transformation temperature, the memory alloy spring recovers, a switch control barrel moves upwards to open the valve, meanwhile the bias spring recovers to a compressed state, when the valve leaks water or an elastic diaphragm is not liable to recover to the original position in the normal state, the bias spring can be adjusted through the handle, and pre-pressure applied to the bias spring adjustment cap is used for reducing the error brought by materials and the ageing phenomenon of memory alloy or the part processing error or the assembling error of the elastic band of the diaphragm.

Description

technical field [0001] The temperature-controlled sprinkler fire valve that can compensate the deformation error of the memory alloy spring belongs to the temperature-controlled fire valve, especially relates to the technical field of the temperature-controlled sprinkler fire valve based on the memory alloy spring whose deformation error can be compensated. Controlled fire valve. Background technique [0002] At present, the temperature-controlled sprinkler fire valve based on the memory alloy spring and the magnetic actuator, such as the application number 201010156537.9 for the invention patent application named "Passive Automatic Fire Spray Valve", due to the material of the memory alloy or the memory alloy spring The deformation error caused by aging caused by plastic deformation and the processing error of the parts make the action of the memory alloy spring easy to make mistakes, such as: water leakage caused by the lax valve switch at normal temperature, and the valve...
