Abstract
The invention relates to a pressure adjusting type pressure stabilizing diaphragm pump which comprises a pump head cap, a pump head end cap matched with the pump head cap, a water inlet-and-outlet piece embedded in the pump head cap and a support plate used to support the pump head cap and the pump head end cap, wherein a balance valve is arranged between the pump head cap and the water inlet-and-outlet piece, and extends into the pump head cap to be connected with the pump head end cap; the joint of the balance valve and the pump head end cap is provided with an adjusting piece which supports the balance valve. When fluid flows from one side of a balance valve high-pressure chamber to one side of a constant pressure chamber, the water pressure of the high-pressure chamber changes and the gap between the balance valve and an annular seal of the pump head cap changes accordingly, thereby ensuring that the fluid pressure inside the constant pressure chamber is always in a constant state; therefore, the diaphragm pump can output constant pressure, which ensures the purification effect of a reverse osmosis water treatment system and prolongs the service life of the diaphragm pump.
Description
Technical field
The present invention relates to a kind of pressure regulating type stabilivolt membrane pump.
Background technique
Along with improving constantly of people's living standard, to the attention of health, people are also more and more higher to the requirement of potable water.Various water purification products are popularized gradually in places such as family, office, factories, the application of the water purification product of especially reverse osmosis, ultrafiltration, nanofiltration type is maximum, simultaneously, the water purification product requirement of types such as reverse osmosis, ultrafiltration, nanofiltration has certain water feeding pressure, but each local pressure of supply water is also unstable, cause water feeding pressure not meet the demands, for this reason, the water purification product of these types is installed diaphragm pump and is used for supercharging.The special-purpose diaphragm pump of the existing RO water purification machine of existing market, generally be divided into two kinds: a kind of is the plain edition diaphragm pump, and along with the increase of water feeding pressure, the also corresponding equal proportion of its delivery pressure increases, but output hydraulic pressure is linear change with incoming pressure, can't export constant compression force.Because reverse osmosis, ultrafiltration, nanofiltration element require to use in certain pressure range, hypotony does not then reach usage requirement.In the process of drainage, because of can being stranded in gradually, the impurity that filters causes obstruction on the barrier film, make high-pressure water flow in the intracranial hyperbaric chamber of pump on the diaphragm pump, can't unimpededly flow in the pump housing, cause local high-pressure water flow to be stranded in this hyperbaric chamber, form the back-pressure phenomenon, cause causing between pump head lid and the pump head end cap the excessive and situation of generation seepage of pressurized easily, shortened the working life of diaphragm pump; Another kind is a stabilized pressure pump, it as the patent No. a kind of diaphragm pump of constant pressure type of 200610104087.2, its patent mainly is equipped with a connecting pipe road between the hydraulic pressure outfall of pump head lid and water intake, its connecting pipeline mutually the position of intersection more is provided with a backflow buffering annular groove at pump head lid internal pressure-regulating groove with relief hole for having the flexible tube of detouring.Unnecessary hydraulic pressure from pump head lid inner high voltage hydroecium, earlier after the backflow buffering annular groove that detours, in regular turn by this hydraulic pressure outfall be disposed to outside the high pressure hydroecium arrive the water intake of pump head lid via this connecting pipeline again after, directly enter in the interior low pressure hydroecium of pump head lid, flow back to the road to constitute a pressure release closed recirculating that is formed by the high pressure hydroecium in the pump head lid, hydraulic pressure outfall, connecting pipeline, water intake and low pressure hydroecium, and then make the turnover water pressure invariableness.But, just can't play the effect of voltage stabilizing when intake pressure during greater than certain value.Reverse osmosis membrane is the core clean unit of reverse osmosis water treatment system, and the reverse osmosis membrane of every kind of specification all has the preceding pressure of a constant film, could guarantee the life-span of water purification effect and reverse osmosis membrane.So because the defective of existing product on the market, delivery pressure is non-constant, and pressure condition is not corresponding with the delivery pressure of pump before the film of each model reverse osmosis membrane, cause the preceding pressure transient of film, purifying effect descends, and the life-span of reverse osmosis membrane reduces.
Summary of the invention

Goal of the invention of the present invention is achieved in that a kind of pressure regulating type stabilivolt membrane pump, the pump head end cap that comprises pump head lid, is complementary with the pump head lid, be flush-mounted in water inlet and outlet spare that pump head covers and the dunnage that is used to support pump head lid and pump head end cap, it is characterized in that: be provided with equilibrium valve between described pump head lid and the water inlet and outlet spare, this equilibrium valve stretches into the pump head lid and is connected with the pump head end cap.
Described equilibrium valve and pump head end cap joint are provided with the pressure regulation part of balance support valve.
The adjusting element that described pump head end cap and can drive the action of pressure regulation part is connected.
Described equilibrium valve, pump head lid and water inlet and outlet spare form the hyperbaric chamber, and equilibrium valve, pump head lid and dunnage form the constant voltage chamber, fluid from the hyperbaric chamber one effluent to the constant voltage chamber.
Described equilibrium valve is through dunnage, and the side that dunnage is connected with the pump head end cap is provided with fixed block, and fixed block is flush-mounted on the equilibrium valve.
Be provided with Sealing between described equilibrium valve and the pump head lid.
Described pressure regulation part is a spring.
Described adjusting element is a nut.
The present invention improves the diaphragm pump of prior art, has set up equilibrium valve in diaphragm pump, and the present invention is had the following advantages:
(1) utilizes the dynamic balance principle of hydraulic pressure, when fluid by equilibrium valve hyperbaric chamber one effluent to constant voltage chamber one side, hyperbaric chamber hydraulic pressure change, the gap of equilibrium valve and pump head bezel ring, shape sealed mouth changes thereupon, to guarantee that constant voltage chamber hydrodynamic pressure is in a constant state all the time and remains unchanged, thereby make diaphragm pump can export constant compression force, guaranteed the purifying effect of reverse osmosis water treatment system, prolonged the working life of diaphragm pump.
(2) be provided with the pressure regulation part of balance support valve in equilibrium valve and pump head end cap joint, the pump head end cap is connected with an adjusting element, and this adjusting element is an adjusting nut.Adjusting element drives the action of pressure regulation part, by the rotation adjusting element, can obtain one group of constant output pressure value, can satisfy the preceding pressure condition of film of the reverse osmosis membrane of different size, different flow.
