At this moment can be rotated bolt 401 keeps it fixed with fixing head 405,401 other end embedment pressure cabin of bolt, 4 outer wall stress, by valve deck
403 are fixed on 6 upper end of water inlet pipe, so that safety valve is closed, it is convenient that spring 2 is safeguarded and adjusted.
Further, the caliber of water inlet pipe 6 is less than the caliber of delivery pipe 5, when the pressure medium in water inlet pipe 6 is excessive, punching
When valve opening lid 403 releases stress, interior media enters pressure chamber 4, then is discharged by delivery pipe 5, because the caliber of delivery pipe 5 is greater than
The caliber of water inlet pipe 6, so that the big pressure medium in water inlet pipe 6 does not cause huge impact to pressure chamber 4, just by delivery pipe 5
Discharge pressure cabin 4, so that pressure chamber 4 be protected not destroyed by the big pressure medium in water inlet pipe 6.
Working principle: firstly, turning moveable cap 201, moveable cap 201 is moved down, holddown spring 2, and moveable cap 201 is upward
When mobile, pull-off spring 2 is turned after the elastic force of spring 2 is adjusted to suitable size by moveable cap 201, by water inlet 601 and high
Pressure vessel or pipeline connection, then discharge outlet 501 is connect with the support container of pressure medium or pipeline, when high-pressure bottle or pipeline
When internal pressure reaches the value of setting, the pressure of spring 2 can not compress valve deck 403, and internal pipe pressure medium enters water inlet
Pipe 6 washes valve deck 403 open, after pressure medium enters pressure chamber 4, then is discharged by delivery pipe 5, discharge after a certain period of time, high-pressure bottle
Or the internal pressure of pipeline reduces, spring 2 compresses valve deck 403 again, and closed safe valve turns bolt 401 when safety valve is closed
Can be fixed by valve deck 403, safety valve can also be fastened not against spring 2, when internal pipe pressure can not automatically turn on safety valve,
Starting bar 3 is pulled to prop cross bar 301, cross bar 301 drives top cover 105 to rise, and top cover 105 pulls main shaft 104 and valve rod 102,
To manually opened valve deck 403.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
