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-60 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, conventional valve block structure is by valve gap in the market, valve block, valve group becomes, but because the valve block controlling in this valve group to commutate is metal circular thin slice, 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 valve block high-frequency vibration (frequency of impact is 18.3HZ), circle sheet creates strong noise, 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-60 Pneumatic breaking pickaxe valve group, adopt the annular valve body of waist-drum-shaped, 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-60 Pneumatic breaking pickaxe valve group, comprise a upper end cover, annular plate valve cabinet is provided with below described upper end cover, annular base body is provided with below described annular plate valve cabinet, described upper end cover lower end is provided with the inner chamber through described annular plate valve cabinet and stretches into the axle portion of the endoporus of described annular base body, described axle subordinate side is arranged with the annular valve body that can slide along axle portion, described annular plate valve forms the first air chamber between side and described upper end cover cashier's office in a shop, forms the second air chamber on the downside of annular plate valve cabinet and between annular base body; Described annular plate valve is provided with the shoulder hole of connection first air chamber and the second air chamber cashier's office in a shop, the middle part of described annular valve body is provided with annular protrusion, the lower surface of described annular protrusion coordinates with the hole platform of the endoporus of annular base body, forms the 3rd air chamber between described annular base body and annular protrusion; Described annular protrusion also can fluctuate along described axle portion between the 3rd air chamber and the macropore of described shoulder hole.
Further, the sidepiece of described annular plate valve cabinet is provided with the cross through hole passing to described first air chamber.
Further, described upper end cover is provided with air admission hole, and described annular plate valve is provided with the vertical through holes being communicated with air admission hole and the second air chamber cashier's office in a shop.
Advantage of the present invention is: TPB-60 Pneumatic breaking pickaxe valve group adopts the annular valve body of waist-drum-shaped, rational in infrastructure, and use reliable, effectively solve the problem that valve block is yielding and easily break, long service life, work noise is little.This annular valve body has two-way salient shoulder type circular seal anchor ring and upper end cover, the sealing surface of annular base body keeps good sealing, simultaneously because annular valve body adopts two lining shoulder guiding, improve annular valve body stationarity at the volley, thus improve the commutating frequency of valve, make the frequency of impact of breakup pick reach 23.33HZ, effectively improve the operating efficiency of breakup pick.
