Abstract
A diaphragm booster pump pressure regulation device is disclosed by the utility model and is arranged on a pump bonnet. A cavity is provided on the pump bonnet. A diversion intake connected to a pump body-type cavity and a diversion outlet connected to a water outlet of the pump and around the diversion intake are provided at bottom of the cavity. The utility model is characterized in that a pressure adjustment holder is fixed in the cavity with tap holes on top and a holder cavity at bottom; adjusting bolts are screwed in the a tap hole; and a spring pad connected to top of the adjusting bolt, a spring arranged on the spring pad and a spring pocket propped up by the spring are provided in the holder cavity; a rubber gasket is arranged at bottom of the cavity, circumference of the rubber gasket is compacted by the pressure adjustment holder and center of the rubber gasket is compacted by the spring pocket to seal the diversion intake and the diversion outlet. The diaphragm booster pump pressure regulation device has the advantages of no leakage, stable pressure regulation and large pressure regulation scope and so on, and is simple in structure.
Description
Technical field
The utility model relates to diaphragm booster pump, especially its regulator.
Background technique
At present, the diaphragm booster pump that uses on the market have the band regulator and not with regulator.Be not a rating value with the shortcoming of the suction booster of regulator for maximum outlet pressure in use, unadjustable, the user need change the pump that maximum outlet pressure must change other models and just can satisfy the demands.Though the suction booster of band regulator can be regulated maximum outlet pressure, this device O of employing type circle seals more, and shortcoming is after long-time the use, O type circle is aging, under high pressure water leakage phenomenon takes place in this device easily, and the pressure regulation instability, and the adjustable pressure scope is little.
The model utility content
Goal of the invention of the present utility model provides the regulator of the diaphragm booster pump that a kind of antileaking, pressure regulation are stable, range of regulation is big and simple in structure, to overcome the deficiency that prior art exists.
In order to realize the foregoing invention purpose, the technical solution adopted in the utility model is:
A kind of regulator of diaphragm booster pump, be arranged on the pump cover, has the cavity that is positioned on the pump cover, cavity bottom has the water conservancy diversion water outlet around the diversion intake that the mouth of a river is pumped in the diversion intake that is communicated to respectively in the pump case die cavity and connection, it is characterized in that: described cavity internal fixation has pressure regulating seat, pressure regulating seat top has tapped hole, the bottom has a chamber, spiral shell has the adjusting bolt in the tapped hole, be provided with in the seat chamber and be connected the spring pad of regulating on the bolt end, be installed in the spring on the spring pad, and the spring housing of replacing by spring, the bottom of cavity is provided with rubber gasket, the neighboring area of this rubber gasket is compressed by pressure regulating seat, and middle section is compressed with sealing diversion intake and water conservancy diversion water outlet by spring housing.
Adopt technique scheme, adopt rubber gasket to replace original O type circle, during work, when the hydraulic pressure in the pump case die cavity was higher than spring and withstands the pressure of rubber gasket, water was promptly discharged from aperture, thereby makes the hydraulic pressure in the pump case die cavity keep constant.Available adjustment bolt Regulation spring withstands the maximum value that the pressure size of rubber gasket is come the hydraulic pressure in the control pump shell mould chamber in the use.The maximum outlet pressure adjustable extent of this device is 40PSI～155PSI.Therefore,
The utlity model has advantages such as antileaking, pressure regulation is stable, range of regulation is big, and simple in structure.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is elaborated:
Fig. 1 colludes the schematic representation of diaphragm booster pump;
Fig. 2 colludes the side view of Fig. 1;
Fig. 3 be Fig. 2 A-A to sectional view;
Fig. 4 be Fig. 2 B-B to sectional view;
Embodiment
Diaphragm booster pump as depicted in figs. 1 and 2, constitute by motor 1 and pump cover 2, wherein the regulator of diaphragm booster pump is arranged on the pump cover 2, as shown in Figure 3 and Figure 4, have a cavity 21 on the pump cover 2, cavity 21 bottoms have the diversion intake 22 in the die cavity 11 that is communicated to motor 1 respectively and are communicated with pumps the mouth of a river 23 and around the water conservancy diversion water outlet 24 of diversion intake 22.By bolt pressure regulating seat 25 is arranged in this cavity 21, pressure regulating seat 25 tops have the tapped hole 26 that constitutes by embedding nut, and the bottom has a chamber 27.Spiral shell has the bolt 28 of adjusting in the tapped hole 26.Be provided with in the seat chamber 27 and be connected the spring pad of regulating on bolt 28 terminations 29, the spring housing 31 that is installed in the spring 30 on the spring pad 29 and replaces by spring 30, the bottom of cavity 21 is provided with rubber gasket 32, the neighboring area of this rubber gasket 32 is compressed by pressure regulating seat 25, and middle section is compressed with sealing diversion intake 22 and water conservancy diversion water outlet 24 by spring housing 31.In order to have good sealing effect, the circumferential cross-section of described water conservancy diversion water outlet 24 is designed to trapezoidal, make the 33 one-tenth tapers of upwards shrinking of block piece between diversion intake 22 and the water conservancy diversion water outlet 24, have seal ring 34 between the periphery of cavity 27 bottoms and the pressure regulating seat 25 in addition.
Diaphragm booster pump (family expenses ultra-filtration water purifier or household reverse osmosis water purifier) in system is installed, turn and regulate bolt and put up with and the maximum outlet pressure of pump can be adjusted to the required hydraulic pressure of system's (family expenses ultra-filtration water purifier or household reverse osmosis water purifier), be intensified pressure clockwise, counterclockwise for reducing pressure.During work, when the hydraulic pressure in the pump case die cavity was higher than spring and withstands the pressure of rubber gasket, water was promptly discharged from aperture, thereby made the hydraulic pressure in the pump case die cavity keep constant.
Claims (3)
1, a kind of regulator of diaphragm booster pump, be arranged on the pump cover, has the cavity that is positioned on the pump cover, cavity bottom has the water conservancy diversion water outlet around the diversion intake that the mouth of a river is pumped in the diversion intake that is communicated to respectively in the motor die cavity and connection, it is characterized in that: described cavity internal fixation has pressure regulating seat, pressure regulating seat top has tapped hole, the bottom has a chamber, spiral shell has the adjusting bolt in the tapped hole, be provided with in the seat chamber and be connected the spring pad of regulating on the bolt end, be installed in the spring on the spring pad, and the spring housing of replacing by spring, the bottom of cavity is provided with rubber gasket, the neighboring area of this rubber gasket is compressed by pressure regulating seat, and middle section is compressed with sealing diversion intake and water conservancy diversion water outlet by spring housing.
