The grouting spray gun has an advanced design, a compact and simple structure, a small size and light weight; a plurality of one-way stop valves are arranged inside the grouting spray gun to satisfy mixing quality; the spray gun does not need to be cleaned by other chemical liquid; after grouting, a gun cleaning gas source ball valve is opened, and the operating handle is rotated by 180 degrees to automatically clean the spray gun for about two minutes, so that the spray gun is not blocked.
Description
Technical field
The present invention relates to a kind of grouting pump in engineering, particularly relate to a kind of slip casting spray gun for the pneumatic Double-liquid mud-injection pump of No clean.
Background technology
Grouting pump is widely used in the grouting for water blocking of the job locations such as mine, tunnel, water conservancy, subway, building, bridge, filling space, reinforces the engineering such as roof, fragmentation.Existing grouting pump has following shortcoming or deficiency:
1, volume is large, weight is large, carrying inconvenience.
2, function singleness, accommodation is narrow.
3, slip casting spray gun easily blocks, and not easy to clean.
4, in the environment changed greatly in inflammable and explosive, temperature humidity, security is poor.
Summary of the invention
The present invention, in order to solve weak point of the prior art, provides a kind of and not easily blocks, is convenient to the slip casting spray gun for the pneumatic Double-liquid mud-injection pump of No clean cleared up.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: for the slip casting spray gun of the pneumatic Double-liquid mud-injection pump of No clean, comprise valve casing 1, valve casing 1 top is provided with the air inlet pipe joint 2 be connected with the gas outlet of air driven pump assembly, valve casing 1 front end is provided with discharge nozzle joint 3, valve casing 1 rear end is provided with feed pipe joint 4, being provided with for controlling the stifled governor motion of the gentle circulation of stream, being provided with the operating grip 5 of control and regulation mechanism outside valve casing 1 in valve casing 1.
Described feed pipe joint 4 is provided with two, described governor motion comprises the spool 6 be located at respectively in two feed pipe joints 4 and two valve rods 7 be slidably connected with valve casing 1, adjacent valve rod 7 arranges with spool 6 is coaxial and is provided with the first Compress Spring 8 between valve rod 7 rear end and spool 6 front end, two valve rods 7 stretch out between the front end outside valve casing 1 and are connected with one piece of baffle plate 9, the second Compress Spring 13 is provided with between baffle plate 9 and valve casing 1, valve casing 1 front end there are upper connective plate 10 and lower linking plate 11, be rotatably connected to one between upper connective plate 10 and lower linking plate 11 and push up the cam 12 of press-fit with baffle plate 9, the rotating shaft 37 of operating grip 5 is fixedly connected with cam 12.
Adopt technique scheme, the present invention adopts extra quality cylinder uprightly synchronously to drive, and stress condition is good, and single plunger double acting makes volumetric efficiency increase substantially, and realizes continuous plasma discharge, and run fluctuation little, air consumption is low, safe and reliable, and energy-saving effect is remarkable.The present invention is widely used in the grouting for water blocking of the job locations such as mine, tunnel, water conservancy, subway, building, bridge, filling space, reinforces the engineering such as roof, fragmentation.Advanced design of the present invention, reasonable compact, small in volume, inside establish the unidirectional retaining valve of multichannel, meet mixing quality, without other chemical liquid cleaning spray guns, open after slip casting completes and wash rifle air source ball valve, rotating operating handle 180 degree, cleaning about two minutes is just passable automatically, can not block up rifle.The present invention and Pneumatic grouting pump with the use of, all can use various chemical raw material and urethane raw, can continued operation and intermittently operated, need not clean, compare with domestic like product, advantage is: volume is little, lightweight simple to operate, real No clean, can cannot not park stickyly rifle head after end of operation for a long time.
Accompanying drawing explanation
Fig. 1 is the structural representation of slip casting spray gun assembly in the middle of the present invention;
Fig. 2 is the upward view of Fig. 1.
Detailed description of the invention
As depicted in figs. 1 and 2, slip casting spray gun for the pneumatic Double-liquid mud-injection pump of No clean of the present invention, comprise valve casing 1, valve casing 1 top is provided with the air inlet pipe joint 2 be connected with the gas outlet of air driven pump assembly, valve casing 1 front end is provided with discharge nozzle joint 3, valve casing 1 rear end is provided with feed pipe joint 4, being provided with for controlling the stifled governor motion of the gentle circulation of stream, being provided with the operating grip 5 of control and regulation mechanism outside valve casing 1 in valve casing 1.Be provided with framework outside air driven pump assembly and material cylinder assembly, air driven pump assembly outside is provided with protective cover.
Feed pipe joint 4 is provided with two, described governor motion comprises the spool 6 be located at respectively in two feed pipe joints 4 and two valve rods 7 be slidably connected with valve casing 1, adjacent valve rod 7 arranges with spool 6 is coaxial and is provided with the first Compress Spring 8 between valve rod 7 rear end and spool 6 front end, two valve rods 7 stretch out between the front end outside valve casing 1 and are connected with one piece of baffle plate 9, the second Compress Spring 13 is provided with between baffle plate 9 and valve casing 1, valve casing 1 front end there are upper connective plate 10 and lower linking plate 11, be rotatably connected to one between upper connective plate 10 and lower linking plate 11 and push up the cam 12 of press-fit with baffle plate 9, the rotating shaft 37 of operating grip 5 is fixedly connected with cam 12.
The course of work of the present invention is: spool 6 is provided with O type circle, can helical pitch seal in the valve opening of feed pipe joint 4, during slip casting, under the effect of slurry pressure, spool 6 is opened automatically, under having the promotion of the first Compress Spring 8 during not slip casting, spool 6 resets, sealing effectiveness is fine, and valve rod 7 is provided with the sealing function rising between O type circle and valve casing 1 and close source of the gas, and the rotating shaft 37 of operating grip 5 is fixedly connected with cam 12.When slip casting, two kinds of different slurries enter respectively by a feed pipe joint 4, first operating grip 5 is revolved turnback, band moving cam 12 rotates, under the effect of the second Compress Spring 13, promote baffle plate 9 to move forward, baffle plate 9 drives two valve rods 7 to move forward, and valve rod 7 resets and closes the path of air inlet pipe joint 2, and the pressure of slurry promotes spool 6 and moves forward the active force overcoming the first Compress Spring 8, slip casting passage is opened, and slurries are sprayed by discharge nozzle joint 3.After slip casting, then operating grip 5 is reversely rotated 180 degree, utilize the centering error of cam 12 to promote baffle plate 9, valve rod 7 is compressed into, open rapidly source of the gas and automatically blow off the inner all residues of valve casing 1, make the first Compress Spring 8 pressed spool 6 simultaneously, long-term press seal effect is played to spool 6.
