Quantitative pressure suction valve

Abstract

The invention discloses a quantitative pressure suction valve which comprises a valve body. A water inlet and a water suction outlet are formed in the two sides of the valve body, a water pressure diaphragm piece is fixed in the upper end of the valve body, and a center flow guide hole is formed in the center of the water pressure diaphragm piece. A sealing column used for blocking the center flow guide hole is pressed at the top of the water pressure diaphragm piece, a downward pressing piece used for pressing the sealing column downwards is installed in an upper cover, an air pressure diaphragm piece is installed in the lower end of the valve body, and an upward ejecting piece used for ejecting the sealing column upwards is installed at the upper end of the air pressure diaphragm piece or between the air pressure diaphragm piece and the sealing column. According to the quantitative pressure suction valve, use of multiple plastic parts such as a water tank and a floating ball is eliminated, and a large amount of material cost can be saved for enterprises and the country; no floating ball is used, and the problems of the defects of congenital air leakage, water inflow and sinking of floating balls are solved; use of a large part of rubber pipes can be reduced, and peculiar smells can be obviously reduced; the quantitative pressure suction valve can rotate by 360 degrees in all directions and do not leak water; the quantitative pressure suction valve can be suitable for various RO reverse osmosis machine types; and pollution caused by long-time contact of water and air can be eradicated.

Description

technical field [0001] The invention relates to a valve, in particular to a quantitative suction pressure valve. Background technique [0002] The valve is a pipeline accessory used to open and close the pipeline, control the flow direction, adjust and control the parameters of the conveying medium. In the wading industry, the internal structure of the traditional pipeline machine has the following defects: [0003] 1. Many plastic parts such as water tanks and floating balls need to be used, and the material cost is relatively high; [0004] 2. The congenital air leakage and water sinking defect of the floating ball has not been resolved; [0005] 3. A large number of rubber hoses used inside have obvious odor phenomenon at high temperature, which has a certain impact on the body; [0006] 4. The pipeline machine cannot be tilted, and the water flow will not stop if the micro-ultrasonic machine is tilted a little bit, which will cause great losses to home decoration; ...

AI Technical Summary

Problems solved by technology

[0003] 1. Many plastic parts such as water tanks and floating balls need to be used, and the material cost is relatively high;

[0004] 2. The congenital air leakage and water sinking defect of the floating ball has not been resolved;

[0005] 3. A large number of rubber hoses used inside have obvious odor phenomenon at high temperature, which has a certain impact on the body;

[0006] 4. The pipeline machine cannot be tilted, and the water flow will not stop if the micro-ultrasonic machine is tilted a little bit, which will cause great losses to home decoration;

[0007] 5. The traditional structure can only be equipped with one type of RO reverse osmosis, and ultrafiltration machines with high water pressure and commercial machines cannot be used;

[0008] 6. The traditional structure is a pressureless open structure, which will be exposed to dust and bacteria in the air, and there will be pollution from air and water contact
