Problems solved by technology

[0003] like figure 1 As shown, when the low-pressure chamber absorbs water from the water storage chamber, the discharge check valve can only ideally cover the drain hole to seal it, and this kind of seal is a face seal, which is prone to leakage; after the booster pump has been in operation for a long time, Dirt and impurities will be deposited on the discharge check valve, and even microorganisms will grow on the sealing surface of the discharge check valve, resulting in the sealing surface not being tightly closed. pump drainage efficiency

Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings.

[0014] like Figure 2-4 As shown, the convex discharge check valve with sealing ribs of the present invention has a spherical crown, and surrounds the drainage hole 3 of the high-pressure chamber 2 of the diaphragm chamber 1, and is divided into three valve discs 4, and the periphery of the lower surface of each valve disc is formed Sealing ribs 5. Preferably, the height of the sealing rib is 0.2-0.7 mm.

[0015] The center of the high pressure chamber is provided with a triangular column hole 6, and the center of the convex discharge check valve is provided with a triangular prism 7, and the triangular prism 7 is pressed into the triangular column hole 6 to assemble the convex discharge check valve into the high pressure chamber .

[0016] like Figure 5 As shown, after the convex discharge check valve is installed in the high pressure chamber, due to the convex e...

Abstract

The invention discloses a convex discharging check valve with sealing ribs. The convex discharging check valve is in a ball coronary shape, wraps a water discharging hole of a high-pressure cavity of a diaphragm chamber and is partitioned into three valve clacks, and the sealing ribs are formed on the peripheral edges of the lower surfaces of all the valve clacks. According to the convex discharging check valve with the sealing ribs, surface sealing is changed into line sealing through the sealing ribs, the sealing degree is increased, the influences on the sealing performance due to the fact that dirt and impurities deposit on sealing surfaces and even microorganisms grow on the sealing surfaces are reduced, high-pressure water is prevented from flowing to a low-pressure cavity to the maximum when the low-pressure cavity conducts water sucking action from a water storage cavity, and pump drainage efficiency is improved.

Description

technical field [0001] The invention belongs to the field of reverse osmosis booster pumps, in particular to a convex discharge check valve with sealing ribs. Background technique [0002] The structure of the existing reverse osmosis booster pump is embodied in that the diaphragm chamber has a low pressure cavity, a high pressure cavity and a water storage cavity, the high pressure cavity is a central concave spherical surface with drainage holes distributed, and the discharge check valve is located in the high pressure cavity and surrounds the high pressure cavity. Drainage hole, there are water suction holes distributed on the low pressure chamber, and the suction check valve covers the suction hole. Under the action of the balance wheel driven by the motor, the water in the water storage chamber is sucked into the low pressure chamber through the water suction hole, and the water is pressed to the high pressure chamber, and the high pressure cavity discharge. [0003]...
