Protective case is sealed, seal protection cover, which is rubber or latex or silica gel material, seal protection cover, makes spring isolating seal, the cavity of bonnet
Interior at least one stop-leak compound storage chamber of setting, stop-leak compound storage chamber include fuel filler neck, and conical bottom, taper is arranged in stop-leak compound storage chamber
Oil outlet, the gap between oil outlet outlet baffle and diaphragm is arranged in bottom bottom, and right baffle-plate and right shell body form communication port,
It forms the right baffle-plate of communication port and smooth filleted corner is arranged for right shell body edge and bull nose reduces the cavitation influence of flow media.
Further, the longitudinally disposed pleated structure of seal protection cover.
Further, stop-leak compound storage chamber is two, relative to lead screw setting substantially symmetrical about its central axis.
Further, automatic pressurizing device is arranged in stop-leak compound storage chamber, pressurizes to the stop-leak compound in stop-leak compound storage chamber.
Compared with prior art, the beneficial effects of the utility model are：It is reasonable in design, better tightness, spring
Seal protection cover is arranged in circumference, and the leakproofness for making valve more comprehensively, has corrosivity or high temperature or contains impurity or have electrochemistry anti-
It is used in the liquid medium answered, also spool part can be protected to be not exposed to corrode, protect the core component of valve, extend spool and valve
Service life；Stop-leak compound storage chamber is set at the sealing between spool spool part and valve cavity, and stop-leak compound storage chamber includes
Fuel filler neck, stop-leak compound storage chamber are arranged conical bottom, and conical bottom bottom is arranged oil outlet, oil outlet outlet baffle and diaphragm it
Between gap, the stop-leak compound placed in stop-leak compound storage chamber conduct oneself with dignity and Self-pressurizing agri under can be flowed to conical bottom, and from fuel-displaced
Mouth is continuously gushed out, with the rotary lubrication and sealed valve core component of lead screw, even if making up impurity under high pressure wears spool
Artificial frequently check and the labour of filling seal grease is saved in sealing between valve body and the leakage generated；Right baffle-plate and the right side
Baffle forms communication port, and smooth filleted corner and bull nose is arranged in the right baffle-plate and right shell body edge for forming communication port, reduces flowing
The cavitation of medium influences, and increases the valve body service life, reduces noise.
