Description
Technical field
The present invention relates to a kind of cleaning equipment auxiliary equipments, more specifically, it relates to a kind of minimum living of jetting machine
Pressure device.
Background technique
Using jetting machine in the process if you need to suspend halfway, need to retain certain pressure in jetting machine upper pump casing,
It can Quick water exit when to restart.But lack self-relieving structure or dress after hydraulic giant is closed in existing jetting machine
It sets, upper pump casing remaining internal pressure is excessive after closing rifle, and there are the risks of booster, and excessively high internal pressure grasps trigger when shooting again
It being greatly increased as power, when shooting, is more painstaking, and because of introducing external pressure after shooting again, pressure oscillation is larger, can generate bright
Aobvious kick, it is on slippery ground to easily lead to hydraulic giant, and water spraying direction deviates, thus the safety in utilization of existing jetting machine compared with
Difference.The utility model patent of Publication No. CN202032138U discloses a kind of low pressure holding of cleaner on November 9th, 2011
Valve, overflow valve are fixed in the pump housing, and low-pressure retaining valve, which covers, forms bayonet, form card column on low pressure holding valve body, the card column blocking
In bayonet, low pressure holding valve body and low pressure holding
Valve deck is placed in the pump housing；The water inlet of low pressure holding valve body against overflow valve overflow valve valve rod and match in the conical surface
It closes, is cased with the first O-ring in the conical surface portion groove of low pressure holding valve body, pressure maintaining spring one end active force is in pump housing inner wall, the other end
Active force is in the top of low pressure holding valve rod, and low pressure holding spring one end active force is in low pressure holding valve rod, other end active force in small pressure
Circle, small pressing ring sleeve form through slot, low pressure holding valve rod and low pressure holding on low pressure holding valve rod on low pressure holding valve rod
The second O-ring is clamped between valve body, low pressure holding valve rod sleeve is in low pressure holding valve body and protrudes into overflowing for overflow valve
It flows in valve valve rod.It installs more efficient and convenient；Low pressure holding valve rod can not only play the role of release, but also play control switch
Effect.But the utility model by through slot pressure release on low pressure holding valve rod when, be only high pressure water is discharged into the pump housing this more
In closed environment, pressure release effect is limited.
Summary of the invention
Lack self-relieving structure or device after hydraulic giant is closed in existing jetting machine, after the rifle of pass in upper pump casing remaining
Pressure is very big, influences the safety in utilization of jetting machine, to overcome this defect, the present invention provides can be automatic after a kind of pass rifle
Eliminate upper pump casing remaining internal pressure, the minimum living pressure device of the better jetting machine of safety.
The technical scheme is that a kind of minimum living pressure device of jetting machine, set on the upper pump casing of jetting machine
In, which includes pressure retaining valve, further includes that piston, mandril and the microswitch that can be triggered by mandril, piston, mandril are sliding
