Abstract
The invention discloses a pneumatic oil injection cut-off valve which comprises a valve body. A valve rod is arranged in the valve body, a cylinder is arranged on top of a valve cover through a bolt, a press cover presses a shaft end sealing assembly in the valve cover, and the valve cover presses a middle sealing assembly on the upper end face of a cone sleeve. An oil injection nozzle is arranged at the lower end of the valve body through a locking nut, a connecting rod and the valve rod of the cylinder are connected through threads, the oil injection nozzle is arranged at the lower end of the valve body, a cone at the lower end of the valve rod is inserted into an inner cone hole of the oil injection nozzle, and the oil injection nozzle is fixed at the lower end of the valve body through the locking nut. The pneumatic oil injection cut-off valve is compact in structure and convenient to operate and does not spray oil in an oil injection process. Oil does not trail or drip after oil injection is finished, and requirements for a mass production line are met.
Description
Technical field
The invention belongs to a kind of stop valve, be specifically related to a kind of pneumatic oiling stop valve.
Background technique
Workpiece on some automatic production line need be finished quantitative oiling under vacuum state, this operation oiling frequency height can not oil spout in the oiling process, oil dripping not after oiling finishes.
Existing fuel feeding valve is normal oil spout in the oiling process, and oiling finishes the oily line hangover in back, oil dripping, can not satisfy the oiling required precision, and the noise height, vibration is big, the life-span is low.
Summary of the invention
The present invention proposes in order to overcome the shortcoming that exists in the prior art, and its objective is provides a kind of pneumatic oiling stop valve.
Technological scheme of the present invention is: a kind of pneumatic oiling stop valve, comprise valve body, be provided with valve rod at body cavity, cylinder is installed on the top of valve gap by double-screw bolt, gland is pressed on shaft end seal spare in the valve gap, and valve gap is pressed on the middle part black box on the upper-end surface of tapered sleeve.Pump nozzle is installed on the lower end of valve body by locking nut, be spiral marking connection between the cylinder column of cylinder and the valve rod, valve body is installed on the connecting plate, is formed with axial oil groove at the outer surface of valve rod, side at valve body 1 forms the oiling entrance, and oiling entrance 14 is vertical with valve rod 2.
The inner chamber of described valve body forms big hole, taper hole and small sircle hole from top to bottom respectively.
Has the gap between the inner conical surface of the male cone (strobilus masculinus) of described tapered sleeve and the taper hole of valve body.
Compact structure of the present invention, easy to operate does not trail after not oil spout in the oiling process, oiling finish, oil dripping not, the response frequency height, and noise free, friction, reliable, but continuous operation adapt to the needs of producing line in enormous quantities.

Embodiment
Below, with reference to drawings and Examples pneumatic oiling stop valve of the present invention is elaborated:,
As shown in Figure 1, 2, a kind of pneumatic oiling stop valve comprises valve body 1, is provided with valve rod 2 at valve body 1 inner chamber, forms big hole 16, taper hole 17 and small sircle hole 18 from top to bottom respectively at the inner chamber of valve body 1.Cylinder 3 is installed on the top of valve gap 8 by double-screw bolt 4, valve gap 8 is pressed on middle part black box 10 on the upper-end surface of tapered sleeve 11, gland 7 is pressed on shaft end seal spare 9 in the valve gap 8, pump nozzle 5 is installed on the lower end of valve body 1 by locking nut 6, is spiral marking connection between the cylinder column 4 of cylinder 3 and the valve rod 2.Valve body 1 is installed on the connecting plate 15.
Shown in Fig. 3,4, form circular cone 19, its cone angle alpha=30 degree in the lower end of valve rod 2, be formed with axial oil groove 20 at the outer surface of valve rod 2.
As shown in Figure 5, flange is formed at the top of tapered sleeve 11, cone 21 is formed at the bottom.
As shown in Figure 6, flange is formed at the top of pump nozzle 5, cone is formed at the bottom, forms internal taper hole 22 in cone, cone angle beta=23 degree in it.The circular cone of valve rod 2 lower ends is inserted in the internal taper hole 22 of pump nozzle 5.Side at valve body 1 forms oiling entrance 12, and oiling entrance 12 is vertical with valve rod 2, has the gap between the inner conical surface of the male cone (strobilus masculinus) of the cone 21 of tapered sleeve 11 and the taper hole 17 of valve body 1.Valve rod 2 is H6/f5 with the cooperation between the aperture 18 of valve body 1.The axial position of valve rod 2 can be adjusted by locking nut 6.
The material of pump nozzle 5 is red copper, and can change by dismounting locking nut 6.
Middle part black box 10 comprises pressing plate and filler, and shaft end seal spare 9 is made up of stuffing box packing.
Working procedure of the present invention is:
Start cylinder, the cylinder bar drives valve rod and rises, the circular cone of valve rod lower end and pump nozzle are broken away from and produce the gap, oil enters in the valve body by the oiling entrance and flows to pump nozzle, the realization oiling along gap and the axial oil groove on the valve rod between the inner conical surface of the male cone (strobilus masculinus) of tapered sleeve and the taper hole of valve body.
Compact structure of the present invention, easy to operate does not trail after not oil spout in the oiling process, oiling finish, oil dripping not, adapts to the needs of producing line in enormous quantities.
