Fig. 2 is the structural representation of this utility model diaphragm type pressure-stabilizing device.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Referring to Fig. 1, Fig. 2, this utility model provides a kind of diaphragm type pressure-stabilizing device, including air chamber base 1, the air chamber cover 2 that is placed on air chamber base, is provided with an air chamber diaphragm 3 in the space that described air chamber base 1 and air chamber cover 2 enclose, and air chamber diaphragm 3 is quality of rubber materials; Described air chamber cover 2 inwall and air chamber diaphragm 3 enclose a plenum space 4; Described air chamber cover 2 is provided with a valve assembly 5 connected with plenum space 4, can pour into air by valve assembly 5 in plenum space 4; Described air chamber base 1 inwall and air chamber diaphragm 3 enclose a hydroecium space 6; Described air chamber base 1 is provided with a union joint 7, and union joint 7 is provided with the through hole 8 connected with hydroecium space 6; One end port that described through hole 8 and hydroecium space 6 connect is provided with partition 9; Described partition 9 is provided with some equally distributed limiting holes 10, and limiting holes 10 and through hole 8 connect.
Described air chamber base 1 opening edge placement is provided with an annular groove 11; Described air chamber diaphragm 3 outer side edges is along being provided with an annular protrusion 12 matched with annular groove 11; Described air chamber diaphragm 3 cross section is bowl-shape.
Described air chamber base 1 is fixed by bolt 13 with air chamber cover 2.
A seal groove 14 it is provided with outside described union joint 7; Being provided with O 15 in described seal groove 14, O 15 is quality of rubber materials.
Described limiting holes 10 number ranges for 5 to 7.
Using method of the present utility model is as follows:
First stable-pressure device is connected on the outlet pipeline in membrane pump outlet system by union joint 7, owing to being provided with seal groove 14 outside union joint 7, O 15 is installed in seal groove 14, therefore under the effect of O 15, make the sealing between union joint 7 and outlet pipeline be protected, do not have the situation of fluid seepage.
The valve assembly 5 then passed through on air chamber cover is connected with external gas source, now external gas source is injected into the air of abundance by valve assembly 5 in plenum space 4, air pressure in plenum space 4 is approximately 5 to 6bar, and the air pressure in plenum space 4 forms balance with the flow stream pressure in hydroecium space 6.
When high pressure liquid stream flows through stable-pressure device, high pressure liquid stream can enter in hydroecium space 6 through limiting holes 10 by the track of through hole 8 on union joint, when the flow stream pressure of high pressure liquid stream is higher than the air pressure in plenum space 4, air chamber diaphragm 3 is moved to plenum space 4 direction by the extruding of high pressure liquid stream, now have more liquid stream and be stored in hydroecium space 6, and when the flow stream pressure in outlet system reduces, the gas of plenum space 4 is extruded to direction, hydroecium space 6 by pressure itself, make the liquid stream in hydroecium space 6 flow in outlet system compensate, play the effect of fluid pulse in stable outlet system.
When the air pressure in plenum space 4 is too more than flow stream pressure in hydroecium space 6, air chamber diaphragm 3 can be extruded towards through hole 8 direction by air pressure always, if port is not provided with partition 9 above through hole 8, air chamber diaphragm 3 part will be squeezed into through hole 8, this situation is as easy as rolling off a log causes that air chamber diaphragm 3 by the abrasion of through hole 8 port edges or is repeatedly stretched folding and breaks, air chamber diaphragm 3 is finally caused to use again, but this utility model is provided with partition 9 by one end port connected in through hole 8 and hydroecium space 6, and several equally distributed limiting holes 10 are set on partition 9, such structural design just can intercept air chamber diaphragm 3 by partition 9 and enter in through hole 8, prevent air chamber diaphragm 3 by the abrasion or folding by repeatedly stretching of through hole 8 port edges, and the limiting holes 10 connected with through hole 8 can make liquid stream flow out normally or flow into hydroecium space 6.
Air chamber base 1 is fixed by bolt 13 with air chamber cover 2, it is ensured that the steadiness connected between the two; And air chamber diaphragm 3 port edges is located just at air chamber base 1 and air chamber cover 2, and air chamber diaphragm 3 is quality of rubber materials, and therefore air chamber diaphragm 3 can play the effect of sealing, it is ensured that air chamber base 1 and the sealing after air chamber cover 2 assembling.
