The utility model is achieved through the following technical solutions:
A kind of braiding packing, including rubber strip, and the first braiding packing and second being wrapped in outside the rubber strip are compiled Packing is knitted, the first braiding packing and the second braiding packing are staggered, and the second braiding packing is set to the first braiding The outside of packing is both provided with card slot at the upper and lower surface location of the rubber strip, and third volume has been embedded in the card slot Packing is knitted, the third braiding packing extends to the outside of the card slot, and the first braiding packing is compressed on the third and compiles The surface of packing is knitted, the third braiding packing is solid construction.
Preferably, in the inside of the rubber strip, there are two grooves for setting above and below, and increasing is provided in the groove Add the inner core item of rubber strip elastic deformation ability, the inner core item is hollow-core construction, between the inner core item and the groove Interference fit, the density of the inner core item are more than the density of the rubber strip, and the inner core item is rubber material, empty by being arranged Heart slot so that the upper and lower end of rubber strip is easily deformable, after flexible deformation, can cover it in valve rod and packing with better seal Between.
Preferably, in the tension item for being internally provided with more increase tensile strength of the rubber strip.
Preferably, the tension item is more helically wound copper wires compositions, a diameter of 0.2mm of single copper wire~ 0.45mm can increase the tensile strength of rubber strip by tension item, avoid being pulled off, and in assembly, need to wind the present apparatus, Caused leak-preventing ability is deteriorated after being stretched to avoid rubber strip by tension item.
Preferably, the side of the rubber strip is provided with concave portion, is provided with and matches in the other side of the rubber strip The female parts for closing the concave portion coordinate female parts by concave portion so that after the completion of winding, allow adjacent rubber Preferably fitting is formed between item.
Preferably, the rubber strip is solid construction.
The utility model has the beneficial effects that:The present apparatus when in use, passes through the second braiding packing and valve rod and packing set Between be in contact, complete outermost sealing, after the second braiding packing generates abrasion, pass through the first braiding packing and third The cooperation of braiding packing can form Subloop Protect, avoid that leakage phenomenon occurs, while third braiding packing is along rubber strip Direction setting, therefore the effect laterally stopped can be played, the first braiding packing of cooperation and the second braiding packing reach more Good sealing effect, the structure of the present apparatus is relatively simple, and cost is more cheap, is suitble to promote the use of.
