Problems solved by technology

Since the high-pressure valve plate is divided into three independent discs by the notch, the bonding area between it and the bottom of the high-pressure chamber of the valve plate is relatively reduced, and the adhesion is also reduced. Insufficient valve clack closing time prolongs; or when one of the valve clacks is not completely closed, the other two valve clacks have been opened, which will easily cause water to flow back from the incompletely closed valve clack to the low pressure chamber, resulting in poor pressure stability

Embodiment 1

[0035] The preferred embodiment discloses a high pressure valve plate of a pressure stabilizing pump. Such as Figure 1 to Figure 4 As shown, the high-pressure valve plate 1 forms at least one groove 13 from the upper surface 11 to the lower surface 12, and a connecting sheet 14 with a set thickness remains between the groove 13 and the lower surface 12.

[0036] The connecting sheet 14 connects the adjacent discs together, effectively increasing the bonding area between the high-pressure valve sheet 1 and the bottom of the high-pressure chamber of the outlet pressure plate, and increasing the bonding force; the connecting sheet 14 makes each valve flap both They are connected to each other and can move independently, and the edge of the connecting sheet 14 is easy to produce effective deformation, and can be opened and closed accurately after the water in the pressurized chamber flows out, ensuring that the two adjacent valve discs are independent of each other and not in the...

Embodiment 2

[0043] The preferred embodiment discloses a valve plate pressure plate assembly. Such as Figure 5 to Figure 8 As shown, the valve plate pressure plate assembly includes a water outlet pressure plate 6 and various high-pressure valve plates 1 as described in the first preferred embodiment, and the high-pressure valve plate 1 is installed on the water outlet pressure plate 6 .

[0044] Preferably, a positioning boss 2 is provided on the lower surface 12 of the high-pressure valve plate 1, and the edge of the positioning boss 2 extends outward to form a rib 21; a positioning counterbore 61 and a positioning groove are provided on the water outlet pressure plate 6 62, the positioning counterbore 61 is compatible with the positioning boss 2, and the positioning groove 62 is compatible with the rib 21.

[0045] The cooperation of the positioning counterbore 61 and the positioning boss, as well as the cooperation of the positioning groove 62 and the rib 21 ensure that the high-pres...

Abstract

The invention discloses a high-pressure valve plate for a pressure stabilizing pump, a valve plate pressure plate assembly and a water purifier, belongs to the field of water purifiers and is designed in order to solve the problems of small adhesive force and the like of existing structures. At least one groove is formed in the high-pressure valve plate for the pressure stabilizing pump in the direction from the upper surface to the lower surface, and a connecting slice with a set thickness is reserved between the at least one groove and the lower surface. The valve plate pressure plate assembly comprises a water outlet pressure plate and the high-pressure valve plate mounted on the water outlet pressure plate. The water purifier comprises the valve plate pressure plate assembly. According to the high-pressure valve plate for the pressure stabilizing pump, the circumferential positioning accuracy of the high-pressure valve plate and the water outlet pressure plate is improved, the combination area of the high-pressure valve plate and the water outlet pressure plate is increased, a valve clack is more accurately opened and closed, and the probability that water in a high-pressure chamber leaks and flows back to a booster cavity is effectively reduced. According to the valve plate pressure plate assembly and the water purifier, the probability that water in the high-pressure chamber leaks and flows back to the booster cavity is effectively reduced, and the pressure stabilizing performance is better.

Description

technical field [0001] The invention relates to the field of water purifiers, in particular to a high-pressure valve plate of a pressure stabilizing pump, a valve plate pressure plate assembly including the high-pressure valve plate, and a water purifier including the valve plate pressure plate assembly. Background technique [0002] The pressure stabilizing pump is the power source of the water purifier, and its stabilizing performance has a great influence on the pre-membrane pressure of the reverse osmosis membrane in the water purifier, which in turn affects the water quality of the water purifier. At present, the pressure stabilizing pump of the water purifier is basically a swash plate pump, and the internal pressure of the three-chamber cycle is mostly used. The sealing performance of the high-pressure chamber plays a vital role in the pressure stabilizing performance of the entire stabilizing pump. The high-pressure valve plate and the pressure water plate form a val...
