Technical Field
[0001] The utility model relates to a gas pressure induction booster valve. Background Art
[0002] The booster gas path is the main part of the pipeline transportation process, and the booster gas path plays the role of plugging. The original booster pressure and flow rate are fixed. However, the pipeline transportation process is not static. If the plug column is too long, the pipeline pressure will increase. When it increases to the upper limit of the delivery pressure, pipe blockage will occur. Utility Model Content

[0006] A reserved port a and a flow hole a communicating with the cavity B are provided on the side wall of the cylinder body corresponding to the cavity B, and an L-shaped hole is provided on the side wall of the cylinder body corresponding to the cavity A. The flow hole B of the L-shaped hole is radial and the flow hole C is axial. The flow hole C faces the cavity A where the large end of the piston is located. The valve block is provided with a common hole and a hole corresponding to the flow hole B of the L-shaped hole. The common hole is communicated with the parallel flow hole a and the flow hole A respectively. The outlet of the cylinder body is connected in series with the first one-way valve, the second one-way valve and the ball valve in sequence.

[0008] Beneficial effects of the utility model: the booster valve of the utility model can automatically adjust the flow rate according to the pressure of the conveying pipeline. When the pipeline pressure increases and exceeds a set value, the booster flow rate will also increase, which can better form the bolt column and better promote material transportation.

[0012] Figure 3 It is a structural schematic diagram of the utility model in use state. DETAILED DESCRIPTION
[0013] The following examples are merely used to illustrate possible implementations of the present invention, but are not intended to limit the scope of protection of the present invention, so it is necessary to make it clear in advance.
[0014] like Figures 1 to 3 As shown, a gas pressure sensing booster valve of the utility model includes a spring pressure regulating sleeve 1, a spring 2, a piston 3, a gland 4, a cylinder body 5 and a valve block 6. One end of the spring 2 is connected to the bottom of the spring pressure regulating sleeve 1, and the other end is connected to the large end of the piston 3. The piston 3 is movably located in the cylinder body 5 under the action of the spring 2. The gland 4 is connected between the cylinder body 5 and the spring pressure regulating sleeve 1. The cylinder body 5 includes a cavity A51 for the piston to extend and retract, and a cavity B52 coaxially connected to the cavity A. The part of the piston close to the tail end is a reduced diameter section, and a small diameter section connected to the cavity A is relatively opened on the side wall of the cylinder body corresponding to the reduced diameter section. The side wall of the cylinder body corresponding to the cavity B52 is provided with a reserved port a55 and a flow hole a56 which are connected to the cavity B52. The side wall of the cylinder body corresponding to the cavity A51 is provided with an L-shaped hole 57. The flow hole B of the L-shaped hole is radial and the flow hole C is axial. The flow hole C faces the large end of the piston 3. The cylinder body 5 is provided with a reserved port B58 which is connected to the large diameter section of the cavity A of the cylinder body where the large end of the piston is located. The valve block 6 is provided with a common hole 61 and a hole 62 which is opposite to the flow hole B of the L-shaped hole. The common hole 61 is connected to the parallel flow hole a56 and the flow hole A54 through the throttle hole. The gas outlet of the cylinder body is connected in series with the first check valve 7, the second check valve 8 and the ball valve 9 in sequence.
[0015] When there is no induction detection (reserved ports a and b are blocked): the air inlet is throttled through the valve block, and the throttled air is discharged from the air outlet. After the pressure at the air outlet increases, the gas enters the cavity A where the piston big end of the cylinder body is located through the valve block. After the cylinder force is greater than the spring force, the piston opens, and the gas at the air inlet directly enters cavity B, and the air outlet discharges a large amount of air. After the pressure at the air outlet drops, it affects the air pressure of the valve block inlet cylinder. After the spring force is greater than the cylinder force, the valve core is closed, and only throttled air is discharged from the air outlet.
[0016] When there is induction detection (reserved port a and reserved port b are in working state): the air inlet is throttled through the valve block, and the throttled air is discharged from the air outlet. After the reserved port b of the rear booster valve detects the pressure increase of the reserved port a of the previous booster valve, the gas of the previous booster valve flows into the reserved port b of the rear booster valve through the reserved port a, pushing the piston of the rear booster valve to move, affecting its cylinder air pressure. After the cylinder force is greater than the spring force, the piston opens, and a large amount of air is discharged from the air outlet of the rear booster valve. After the reserved port b of the rear booster valve detects the pressure drop of the previous booster valve, it affects the air pressure of the cylinder inlet of the valve block of the rear booster valve. After the spring force is greater than the cylinder force, the piston of the rear booster valve is closed, and only throttled air is discharged from the air outlet. This connection of adjacent booster valves plays a leading role and can better push materials.
