Detailed description of the invention
With specific embodiment, this utility model is further described below in conjunction with the accompanying drawings, sees Fig. 13:
Spraying machine pressure regulator valve, is provided with into water with the surge pipe 2 being arranged on backwater body 1, backwater body 1 including backwater body 1
Mouthfuls 3 with outlet 4, water inlet 3 is provided with valve seat 5, is provided with to coordinate with valve seat 5 blocks water inlet 3 in described backwater body 1
Spool 6, the other end of the valve rod 7 that one end apical grafting is connected on spool 6 or with spool 6 extend in surge pipe 8, outside surge pipe 8
Being bolted with pressure adjusting roller 9, the top of pressure adjusting roller 9 is bolted with pressure adjusting lever 10, is provided with pressure regulation between pressure adjusting lever 10 and spool 6
Spring 11, pressure adjusting roller 9 lateral wall is provided with pressure scale dish 12, and the lateral wall of backwater body 1 or surge pipe 2 is provided with finger at pressure
Tuning drive gear 13 on graduated disc 12, can drive pressure adjusting lever 10 compression pressure spring when pressure adjusting roller rotates forward or backwards
11, change the compression spring 11 active force to valve rod 7, and then play regulation hydraulic pressure purpose, the active force of compression spring 11 with
Scale on pressure scale dish 12 is corresponding, when this utility model is connected on spraying machine use, as pressure spring sets pressure
During for 4Ma, tuning drive gear 13 also indicates that the 4MPA position on pressure scale dish 12；The adjustment of spray gun causes the hydraulic pressure in pump big
When 4MPA, press water overcomes the active force of pressure spring 11, is backed down by spool 6, press water outlet 4 from backwater body 1
Flowing out, when the pressure reduction in pump is stabilized to 4MPA or below 4MPA, compression spring 11 acts on spool 6 fight back on valve rod 7
Making itself and valve seat 5 fitted seal, water inlet 3 is closed.
It is provided with water seal seat 14 between above-mentioned backwater body 1 and surge pipe 2 and is fixed the pressing plate 15 of water seal seat 14, pressure
It is set with water seal 16 on valve rod 7 between plate 15 and water seal seat 14, is provided with O between water seal seat 14 and backwater body 1, incites somebody to action back
The inner chamber of water body 1 seals off with the inner chamber of surge pipe 2, makes water cannot enter in surge pipe 2 from backwater body 1.
It is provided with latch bracket 17, the other end of pressure spring 11 and pressure between one end and the valve rod 7 of above-mentioned pressure spring 11
Spring top 18 it is provided with between draft control lever 10.
On the medial wall of above-mentioned pressure adjusting roller 9, circumference is arranged at intervals with draw-in groove 19, and the lateral wall of surge pipe 2 is provided with cocker
Shell fragment 20 in draw-in groove 19, the medial wall of pressure adjusting roller 9 has been radially arranged stroke limit bar 21 and maximum pressure gag lever post 22,
Stroke limit bar 21 and maximum pressure gag lever post 22 are the screw being screwed onto on pressure adjusting roller 9, on the lateral wall of surge pipe 2 outwards
Extending to be formed and limit the boss 23 that stroke limit bar 21 rotates with maximum pressure gag lever post 22, described shell fragment 20 is arranged on boss
On 23 or shell fragment 20 is fixed on the bottom of surge pipe 2 and shell fragment 20 top extend into pressure adjusting roller 9 in be positioned at the footpath outside boss 23
On direction, when pressure adjusting roller 9 rotates, shell fragment 20 is stuck on the draw-in groove 19 of pressure adjusting roller 9, and pressure adjusting roller 9 rotates forward to maximum pressure
During value, now tuning drive gear 13 points to the maximum pressure value of pressure scale dish 12, and maximum pressure gag lever post 22 is stopped by boss 23,
Make pressure adjusting roller 9 can not continue to rotate forward；When pressure adjusting roller 9 rotates backward to minimum pressure values, i.e. tuning drive gear 13 points to pressure
During the zero graduation of graduated disc 12, stroke limit bar 21 is stopped by boss 23, makes pressure adjusting roller 9 can not continue to rotate backward.
