Water inlet valve, flow rate calculating and calibrating method and flow rate calculating and calibrating device

Abstract

The invention relates to the field of valve bodies and provides a water inlet valve, a flow rate calculating and calibrating method and a flow rate calculating and calibrating device. The water inletvalve comprises a valve body, wherein a central channel is arranged in the middle of the valve body; a flow rate control device is arranged on the outer side of the central channel and comprises a flow rate seat; a plurality of flow rate columns are arranged on the flow rate seat and are made of elastic material; a water passing area is arranged between the flow rate seat and the central channel;the valve body is matched with a rubber sheet; and a hollow water passing gap is formed among two adjacent flow rate columns, the flow rate seat and the rubber sheet and communicates with the water passing area. A flow rate and pressure characteristic analyzing system and calculating method combine the variable and constant elements of the water inlet valve. The variable is the water passing areabetween the heights of different flow rate columns of the flow rate seat and the rubber sheet under different pressures and aims to analyze and master the flow rate variation values within different pressure scopes. A model disclosed by the invention can be used in a computer or independently.

Description

technical field [0001] The invention belongs to the field of valve bodies, and relates to a water inlet valve, in particular to a water inlet valve, a flow calculation and verification method and a calculation and verification device. Background technique [0002] The water inlet valve is a common valve body, usually only has two working states of fully open or fully closed, and cannot be used to adjust the flow; while domestic water inlet valves that can be used to adjust the flow are mostly imported from Europe, the United States or Japan And production, only existing, designed valves can be used. At present, our country lacks a lot of theoretical aspects such as designing the structure of valves and calculating the flow of control valves, and it is impossible to truly realize the assembly line of independent research and development, independent calculation, and independent production. Although the demand for domestic valves is getting higher and higher, some profits are ...

At present, our country lacks a lot of theoretical aspects such as designing the structure of valves and calculating the flow of control valves, and it is impossible to truly realize the assembly line of independent research and development, independent calculation, and independent production. Although the demand for domestic valves is getting higher and higher, some profits are still Flowing abroad, the cost cannot be reduced
