Description
Technical Field
The utility model relates to a pulse damper, more specifically the automatic control pulse damper who is used for the diaphragm pump that says so.
Background
The existing pulse damper needs to manually control an air inlet valve on the pulse damper, so that the operation is extremely inconvenient, and the pulse damper is easy to fail due to misoperation.
Disclosure of Invention
Because of the above-mentioned problem of prior art, the utility model provides an automatic control pulse damper, it can effectual solution above-mentioned problem.
The technical scheme adopted by the utility model for solving the technical problems is to provide an automatic control pulse damper, which comprises a shaft sleeve, a piston, an upper cover, a lower cover, a diaphragm and a clamping plate, wherein the shaft sleeve is arranged at the center of the top of the upper cover, and a counter bore is arranged at the center of the shaft sleeve; the piston is arranged in a counter bore of the shaft sleeve and can slide up and down; a diaphragm is arranged between the upper cover and the lower cover, and the space between the upper cover and the lower cover is divided into an air cavity and a fluid cavity by the diaphragm; the center of the diaphragm is fixedly connected with the end face of the piston through a clamping plate.
Furthermore, the shaft sleeve is provided with a first air inlet, a second air inlet, a first exhaust hole and a second exhaust hole; the first air inlet is communicated to the air cavity; and the air inlet hole II, the air outlet hole I and the air outlet hole II are communicated to the counter bore on the shaft sleeve.
Furthermore, a vent hole is formed in the piston; the vent hole is communicated to the air cavity.
The utility model has the advantages that: the utility model provides a pair of automatic control pulse damper has increased inlet port two and exhaust hole two and has passed through the upper and lower slip automatic control pulse damper's of piston admit air and exhaust on the axle sleeve, need not artifical manually operation.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic cross-sectional view of the present invention;
fig. 2 is a schematic sectional view of the bushing of the present invention;
fig. 3 is a schematic cross-sectional view of the piston of the present invention.
Detailed Description
The following further explains the specific embodiments of the present invention with reference to the drawings:
as shown in fig. 1, the utility model provides an automatic control pulse damper, which comprises a shaft sleeve 1, a piston 2, an upper cover 3, a lower cover 4, a diaphragm 5 and a clamping plate 6, wherein the shaft sleeve 1 is installed at the center of the top of the upper cover 3, and a counter bore 15 is arranged at the center of the shaft sleeve 1; the piston 2 is arranged in a counter bore 15 of the shaft sleeve 1 and can slide up and down; a diaphragm 5 is arranged between the upper cover 3 and the lower cover 4, and the diaphragm 5 divides the space between the upper cover 3 and the lower cover 4 into an air cavity 7 and a fluid cavity 8; the center of the diaphragm 5 is fixedly connected with the end face of the piston 2 through a clamping plate 6.
As shown in fig. 1 and 2, an air inlet hole i 11, an air inlet hole ii 12, an air outlet hole i 13, and an air outlet hole ii 14 are formed in the shaft sleeve 1; the first air inlet 11 is communicated to the air cavity 7; the second air inlet hole 12, the first air outlet hole 13 and the second air outlet hole 14 are communicated with a counter bore 15 on the shaft sleeve 1.
As shown in fig. 1 and 3, a vent hole 21 is formed in the piston 2; the vent hole 21 communicates to the air chamber 7.
The utility model discloses a working process includes: when the pressure of the liquid to be conveyed is too high, the diaphragm 5 drives the piston 2 to move upwards, when the liquid to be conveyed moves to a set stroke, the compressed air enters the air cavity 7 through the air inlet hole II 12 to compensate the pressure, when the pressure of the liquid to be conveyed is too small, the diaphragm 5 drives the piston 2 to move downwards, and when the liquid to be conveyed moves to the set stroke, the compressed air releases the pressure through the air outlet hole II 14.
The utility model provides a pair of automatic control pulse damper is equipped with two 12 of inlet port and two 14 in exhaust hole on the axle sleeve 1, plays the effect of automatic compensation pressure and release pressure to realize pulse damper's automatic control.
The above description is only a preferred example of the present invention and should not be taken as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention should be included in the scope of the present invention.
