Description
Technical field
The present invention relates to effusion meter manufacture field, in particular to a kind of critical speed flowmeters and tubing.
Background technology
Critical speed flowmeters operation principle is according to gas dynamics, when gas passes through critical flow nozzle, nozzle
Upstream and downstream stream pressure ratio is reached under conditions of a certain special value, and in nozzle throat critical stream mode is formed, and air-flow reaches most
Big speed (velocity of sound).The gas mass flow for flowing through nozzle also reaches maximum.Now only with nozzle entrance at stagnation pressure
It is relevant with temperature, and do not affected by state change downstream.When measuring natural gas for example with critical speed flowmeters, gas
By orifice plate, upstream pressure is more than about one times of downstream pressure, reaches critical gas flows.In critical gas flows, at flow velocity section minimum,
The flow velocity of natural gas is equal to the velocity of sound in natural gas at such a temperature.Now, upstream pressure, the speed at flow velocity section minimum are increased
Degree does not increase, and only increases the density and flow of gas, therefore can calculate outflow using upstream pressure.
Existing effusion meter needs pipeline to remove when orifice plate is exchanged for, also to remove instrument mounted thereto
Box, high labor intensive, complex operation and to operator require it is higher, change while easily leak, if toxic gas
Increased the danger coefficient of operator.
