The technological scheme that provides according to the utility model, described particle-resistant High Pressure Difference angle valve, comprise valve body, valve gap, valve rod and valve seat, valve gap is fixedly mounted on the valve body, at the valve body internal fixation valve seat is installed, in valve gap, be plugged with valve rod, in the valve pocket of valve body, be provided with the particle-resistant sleeve, the bottom of described particle-resistant sleeve is seated on the valve seat, be provided with gland on particle-resistant sleeve top, gland and valve seat are fixed in the particle-resistant sleeve in the valve pocket of valve body, are fixedly connected with the particle-resistant spool in the bottom of valve rod, and described particle-resistant spool cooperates with valve seat.
On valve rod, be socketed with filler, on the valve rod below the filler, be socketed with the filler spacer, be socketed with matrix liner on the valve rod of filler spacer below, on the valve rod above the filler, be socketed with the filler gland.On the outer wall of filler gland, be provided with an O type circle, on the endoporus perisporium of filler gland, be provided with the 2nd O type circle.
On particle-resistant sleeve endoporus wall body, offer chute in the annular.
Described particle-resistant spool is the flat body structure of segmentation.
Between particle-resistant sleeve and gland, be provided with the balanced seal ring.
The utility model has satisfied the conveying requirement of the granule medium under the different condition, and prolonged the working life of valve, the medium that can satisfy fully under the particle High Pressure Difference operating mode is regulated and the switch requirement, has saved spare part cost and maintenance cost, without any need for safeguarding and buy spare part.

Embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure, the utility model mainly is made of parts such as valve body 1, valve gap 2, particle-resistant spool 3, valve rod 4, valve seat 5, particle-resistant sleeve 6, gland 7, balanced seal ring 8, straight pin 10, an O type circle 31, the 2nd O type circle 32, matrix liner 33, filler 34, filler spacer 35, filler gland 36, hold-down grid 37, stud 38, locking nut 39, belleville spring 40, stud 51, hexagon nut 52, valve washer 53 and valve gap packing rings 54.
This particle-resistant High Pressure Difference angle valve, comprise valve body 1, valve gap 2, valve rod 4 and valve seat 5, valve gap 2 is fixedly mounted on the valve body 1 by stud 51 and hexagon nut 52, the bottom end of valve gap 2 is provided with valve gap packing ring 54, on valve gap 2, be installed with hold-down grid 37 by stud 38 and locking nut 39, on the stud below the locking nut 39 38, be socketed with belleville spring 40, at valve body 1 internal fixation valve seat 5 is installed, be provided with valve washer 53 at valve seat 5 bottom ends, in valve gap 2, be plugged with valve rod 4, in the valve pocket of valve body 1, be provided with particle-resistant sleeve 6, the bottom of described particle-resistant sleeve 6 is seated on the valve seat 5, be provided with gland 7 on particle-resistant sleeve 6 tops, gland 7 is fixed in particle-resistant sleeve 6 in the valve pocket of valve body 1 with valve seat 5, and the particle-resistant spool 3 that has been threaded in the bottom of valve rod 4 is fastening by straight pin 10, can gain in strength, described particle-resistant spool 3 cooperates with valve seat 5.
On valve rod 4, be socketed with filler 34, on the valve rod below the filler 34 4, be socketed with filler spacer 35, be socketed with matrix liner 33 on the valve rod 4 of filler spacer 35 belows, on the valve rod above the filler 34 4, be socketed with filler gland 36.On the outer wall of filler gland 36, be provided with an O type circle 31, on the endoporus perisporium of filler gland 36, be provided with the 2nd O type circle 32.
