Abstract
The present invention relates to a kind of TPB-40 Pneumatic breaking pickaxe valve group, comprise a valve seat, be buckled in the valve gap on described valve seat, and be positioned at the valve body of described valve base cavity, the inside of described valve seat is provided with three sections of reducing holes, the hole platform that described valve body is positioned at mider hole is socket-connected by the axle portion of its lower end and bottom hole, described valve body is provided with the vertical through holes being communicated with upper hole and bottom hole, the sidepiece of described valve seat is provided with the cross through hole passing to described mider hole, the sidepiece of described valve gap is provided with the breach communicated with the upper hole of described valve seat, the gap in order to air inlet is left between described valve gap and described valve body.This TPB-40 Pneumatic breaking pickaxe valve block structure is reasonable, and use reliable, effectively solve the problem that valve block is yielding and easily break, long service life, work noise is little.
Description
Technical field
The present invention relates to the reversal valve group that a kind of Pneumatic breaking pickaxe uses, be specifically related to a kind of TPB-40 Pneumatic breaking pickaxe valve group.
Background technology
Mainly breakup pick is in the course of the work for the effect of valve group, control airflow-reversing, thus reach hammer body and can carry out the impact pick rod that moves up and down, reach working effect, valve block structure conventional is in the market become by valve gap, valve block, valve group, but due to its structure of valve block controlling to commutate in this valve group be the sheet metal of thinner thickness.This valve block easily produces distortion and slight crack in high-frequency impact use procedure, affect air flue commutation sealing effectiveness and affect operating efficiency, and due to the vibration of valve block high-frequency, circle sheet creates strong noise, and Long-Time Service has had a strong impact on the healthy of operator.
Summary of the invention
In view of this, the object of this invention is to provide a kind of TPB-40 Pneumatic breaking pickaxe valve group, adopt the valve body of the valve bush type of high shape for hat, effectively overcome the defect that valve block is yielding and easily break, and noise when reducing disintegrating machine work.
The present invention adopts following scheme to realize: a kind of TPB-40 Pneumatic breaking pickaxe valve group, comprise a valve seat, be buckled in the valve gap on described valve seat, and be positioned at the valve body of described valve base cavity, the inside of described valve seat is provided with three sections of reducing holes, the hole platform that described valve body is positioned at mider hole is socket-connected by the axle portion of its lower end and bottom hole, described valve body is provided with the vertical through holes being communicated with upper hole and bottom hole, the sidepiece of described valve seat is provided with the cross through hole passing to described mider hole, the sidepiece of described valve gap is provided with the breach communicated with the upper hole of described valve seat, the gap in order to air inlet is left between described valve gap and described valve body.
The advantage of this invention is: this TPB-40 Pneumatic breaking pickaxe valve group, adopt the valve body of the valve bush type of high shape for hat, effectively solve the problem that valve block is yielding and easily break, rational in infrastructure, use reliable, long service life, work noise is little, valve body has two-way circular seal anchor ring simultaneously, and moving up and down of valve body adopts axle portion guiding, ensure that the two way seal anchor ring of valve body at the volley and the sealing surface of valve seat and valve gap keep good sealing, thus ensure that normal work and the operation of breakup pick.
Accompanying drawing explanation
Fig. 1 is TPB-40 Pneumatic breaking pickaxe valve block structure schematic diagram of the present invention.
Fig. 2 is the A-A cross-sectional view of Fig. 1.
Fig. 3 is the breakup pick structural representation with this invention valve group.
Detailed description of the invention
For making object of the present invention, technical scheme and advantage clearly understand, below by specific embodiment and relevant drawings, the present invention will be described in further detail.
As depicted in figs. 1 and 2, a kind of TPB-40 Pneumatic breaking pickaxe valve group, comprise a valve seat 2, be buckled in the valve gap 7 on described valve seat 2, and be positioned at the valve body 6 of described valve seat 2 inner chamber, the inside of described valve seat 2 is provided with three sections of reducing holes (1, 4, 8), the hole platform that described valve body 6 is positioned at mider hole 4 is socket-connected by the axle portion of its lower end and bottom hole 1, described valve body 2 is provided with the vertical through holes 9 being communicated with upper hole 1 and bottom hole 8, the sidepiece of described valve seat 2 is provided with the cross through hole 3 passing to described mider hole, the sidepiece of described valve gap 7 is provided with the breach 10 communicated with the upper hole 8 of described valve seat, the gap in order to air inlet is left between described valve gap 7 and described valve body 6.
As shown in Figure 3, be the breakup pick structure diagram with this TPB-40 Pneumatic breaking pickaxe valve group, comprise cylinder 13, hammer body 12 and handle body 11, described valve gap 7 upper end connection handle body 11, described valve seat 2 lower end connects cylinder 13.
The course of work of TPB-40 Pneumatic breaking pickaxe valve group of the present invention: during breakup pick work, the gap → vertical through holes 9 between the breach 10 → valve gap 7 of gas on valve gap 7 and valve seat 2, promotes hammer body 12 and moves downward, start stroke.During backhaul, Compressed Gas backs down valve body 6, and valve body 6 moves, and gas, through the gap → cross through hole 3 between breach 10 → valve body 6 and valve seat 2 → enter cylinder 13, promotes hammer body 12 moves, starts backhaul.
Above-listed preferred embodiment; the object, technical solutions and advantages of the present invention are further described; be understood that; the foregoing is only preferred embodiment of the present invention; not in order to limit the present invention; within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
