Detailed Description
The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings and the detailed description, but those skilled in the art will understand that the following described embodiments are some, not all, of the embodiments of the present invention, and are only used for illustrating the present invention, and should not be construed as limiting the scope of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1
Referring to fig. 1, a speed-adjustable handheld grouting device with a non-return function according to an embodiment 1 of the present invention includes: syringe 1, hose 2, flow rate regulator 3, non-return device 4 and rigid tube 5.
Specifically, one end of the hose 2 is connected with the output end of the injector 1 in a plug-in connection manner; the flow rate regulator 3 is sleeved on the hose 2, and the flow rate regulator adopts a common flow rate regulator structure; the backstop 4 is connected with the hose 4; the tube 5 is connected to the end of the hose 2 remote from the syringe 1. The hard tube is pegged graft with hose one end, can change the hard tube of different length or diameter according to particular case during the use, improves the flexibility of using.
During actual operation, the devices are configured in relative quantity according to initial setting time of cement paste and total grouting square amount. After the cement paste is debugged, the tank is fully pumped by an injector, the hose is connected, the grouting hole is reserved in the embedded part after the hard tube is inserted, the cement paste is pushed into the concrete structure main body, when the cement paste is obtained again, the injection and the hose are disconnected, the cement paste is pumped again, the cement paste is injected repeatedly, and the cement paste injected into the grouting hole after the injector is pulled out cannot flow back due to the action of the non-return device.
To explain further, referring to fig. 2, the non-return device 4 includes a flow pipe 41, an arc groove 42 is provided on the inner wall of the bottom of the flow pipe 41, a ball 43 is movably provided in the arc groove 42, an accommodating pipe 44 is provided on the top of the flow pipe 41, and the accommodating pipe 44 is inclined along the direction of the fluid flow; one end of the accommodating pipe 44 extends into the flow pipe 41, the top end of the ball 43 extends into the accommodating pipe 44, and the ball 43 can enter the accommodating pipe 44 by the thrust of the fluid. When the ball is used, the ball is flushed into the accommodating pipeline under the continuous grouting pressure, and the small ball falls back into the circulating pipeline after no grouting pressure exists, so that the non-return function is realized.
For better use of the embodiment, the two ends of the arc-shaped groove 42 are divided into a flat end 45 and a lower end 46, the flat end 45 is disposed near the inlet of the circulating pipe 41, the lower end 46 is disposed away from the inlet of the circulating pipe 41, and the lower end 46 is chamfered along the flowing direction of the fluid. Because the low-end blocking area is small, the ball body can conveniently slide into the accommodating cavity from the low end, and meanwhile, the mud can conveniently flow. A spring 47 is arranged in the accommodating pipeline 44, the spring 47 and the accommodating pipeline 44 are positioned on the same axial line, one end of the spring 47 is fixedly connected with the top end of the pipeline 44, and the other end of the spring 47 is a free end. When the grouting pressure is not available, the ball body can be rebounded to the arc-shaped groove by the spring rapidly, and the non-return purpose is achieved.
Example 2
The speed-adjustable handheld grouting device with the non-return function provided by the embodiment 2 of the utility model is basically the same as the embodiment 1, and the difference is that the non-return device 4 is a non-return valve.
The utility model is not limited to the above alternative embodiments, and any other various forms of products can be obtained by anyone in the light of the present invention, but any changes in shape or structure thereof, which fall within the scope of the present invention as defined in the claims, fall within the scope of the present invention.
