Abstract
The utility model discloses a wet-type concrete sprayer air inlet valve, which comprises an oil cylinder and an air valve, wherein a piston rod of the oil cylinder is connected with a gag lever post of a spring holder of a buffer, a shell of the baffler is connected with the piston rod of the air valve, the spring holder is installed in the shell, and two sides of the spring holder are respectively provided with springs. The piston rod of the oil cylinder drives the spring holder of the baffler to move, the shell of the baffler drives the piston rod of the air valve to move, since both the left side and the right side of the spring holder of the baffler are provided with the springs, under the baffle effect of the springs, the movement and the reversing of the air valve are enabled to be stable, and simultaneously the service life of the air valve is prolonged. The air inlet valve is used in wet-type concrete sprayers.
Description
Technical field
The utility model relates to a kind of wet concrete sprayer suction valve.
Background technique
The utility model is a Mine Tunnel Construction wet concrete sprayer suction valve; Adopt now the dry type concrete sprayer to carry out roadway construction in the Mine Tunnel Construction, dust, noise are big, pollute surrounding environment, and it is healthy to influence the staff; Rebound of shotcrete rate height causes the material significant wastage, and concrete strength is not high, has potential safety hazard.
Summary of the invention
The purpose of this utility model provides a kind of wet concrete sprayer suction valve, and described wet concrete sprayer suction valve is by the conversion of oil cylinder by the piston rod control gas circuit of buffer drive air valve, stable working; Adopt wet concrete sprayer to spray the concrete operation and can effectively reduce dust, noise, the protection personnel are healthy; Reduce the rebound of shotcrete rate, economical with materials; Improve sprayed concrete strength, improve the roadway support level.
A kind of wet concrete sprayer suction valve comprises oil cylinder and air valve, and the piston rod of oil cylinder is connected with the position-limited lever of the spring seat of buffer, and the housing of buffer is connected with the piston rod of air valve; Spring seat is loaded in the housing, and the both sides of spring seat respectively are provided with spring.
The utility model is made of air valve, oil cylinder and buffer; The piston rod of oil cylinder drives the spring seat motion of buffer, and the buffer housing drives the piston rod movement of air valve; Because the and arranged on left and right sides of the spring seat of buffer all is provided with spring, under the buffer function of spring, the motion, commutation that make air valve are steadily; Prolonged the life-span of air valve simultaneously.
Description of drawings
Fig. 1 is the utility model schematic representation.
Embodiment
Further specify the utility model below in conjunction with drawings and Examples.
A kind of wet concrete sprayer suction valve comprises oil cylinder 1 and air valve 3, and the piston rod of oil cylinder 1 is connected with the position-limited lever of the spring seat 4 of buffer 2, and the housing 7 of buffer 2 is connected with the valve rod 8 of air valve 3; Spring seat 4 is loaded on 7 li of housings, and the both sides of spring seat 4 are respectively equipped with spring 5 and spring 6 (see figure 1)s.During work, the piston rod of oil cylinder 1 drives spring seat 4 to left movement, and spring seat 4 pressure springs 5 move to left spool 9 by the valve rod 8 that housing 7 drives cylinder again, and the suction port 12 of air valve 3 is communicated with left air outlet 10; When the piston rod drive spring seat 4 of oil cylinder 1 moved right, spring seat 4 pressure springs 6 and the valve rod 8 that drives cylinders by housing 7 moved to right spool 9, and the suction port 12 of air valve 3 is communicated with right air outlet 11; Since the buffer function of spring, when the left and right motion of air valve commutates, stable action, noise free; Also prolonged simultaneously the life-span of air valve.
