Abstract
The utility model discloses integrated welded type ring casing pressure orifice plate, it comprises positive ring flange (1), positive ring casing (2), orifice plate (3), pad (4), negative ring casing (5) and negative ring flange (6), positive ring flange (1) and positive ring casing (2) are cast as one, negative ring flange (6) firmly causes one with negative ring casing (5), positive ring casing (2), symmetrical grooves (7) is established on the composition surface of negative ring casing (5), orifice plate (3) and pad (4) is put in groove (7), the negative ring casing (5) of positive ring casing (2) welding, being integrally formed of entirety welded type ring casing pressure orifice plate.The utility model structure is simple, and easy for installation, solid and reliable, measuring accuracy is high, and measuring media scope is large.
Description
Technical field
The utility model relates to ring casing orifice plate, is specifically related to integrated welded type ring casing pressure orifice plate.
Background technology
As everyone knows, ring casing orifice plate is mounted in ducted restriction device, then in conjunction with differential pressure transmitter, the pressure reduction before and after measuring diaphragm.After measured medium flows through ring casing orifice plate, cause a local contraction, flow velocity is concentrated, and flow velocity increases, and static pressure reduces, so produce a static pressure difference in the both sides, upstream and downstream of orifice plate, in certain funtcional relationship between this static pressure difference and flow, flow is larger, and the static pressure difference produced is larger, therefore by measuring the method for differential pressure, just flow can be recorded.
Ring casing pressure orifice plate is formed by installing orifice plate between positive ring casing and negative ring casing, belong to standard orifice plate, achieve ring casing pressure, improve measuring accuracy, required minimum rectilinear tubes segment length when shortening installation, ring casing orifice plate can the flow of measurement gas, steam, liquid and natural gas, is widely used in process control and the measurement in the fields such as oil, chemical industry, metallurgy, electric power, heat supply, water supply.But there is certain defect in them, be exactly after mounting positive ring casing and negative ring casing easily move up and down, security is poor, nor can measure the fluid of high pressure.
Summary of the invention
The purpose of this utility model is: provide integrated welded type ring casing pressure orifice plate, easy for installation, solid and reliable, adopts multiple spot ways of measure pressure, improves measuring accuracy, expands measuring media scope.
Technical solution of the present utility model is: this integrated welded type ring casing pressure orifice plate comprises positive ring flange, positive ring casing, orifice plate, pad, negative ring casing and negative ring flange, positive ring flange welds positive ring casing, the negative ring casing of negative ring flange welding, symmetrical grooves is established on the composition surface of positive ring casing, negative ring casing, orifice plate and pad is put in groove, the negative ring casing of positive ring casing welding, being integrally formed of entirety welded type ring casing pressure orifice plate.
The utility model has the advantages that: when 1, welded type ring casing orifice plate is installed, positive ring casing, negative ring casing, orifice plate and pad integralization, well can be fixed on orifice plate between positive and negative ring casing, avoid moving up and down; 2,
Ring casing and flange are cast as one, convenient, reliably, substantially increase work efficiency, also improve the security of ring casing orifice plate; 3, welded type ring casing orifice plate is considerably beyond traditional ring casing orifice plate in use differential pressure and pipe diameter usable range, reduces the pressure loss; 4, welded type orifice plate achieves the mode of multiple spot pressure, improves measuring accuracy and stability; 5, in the medium scope of application, also become relatively wider, can to the flow measurement of various liquid, gas and steam; 6, flange and ring casing are cast as one, and positive and negative ring casing is integrally welded, and positive and negative ring casing weld in an installation can sealed engagement more, makes ring casing orifice plate more safe and reliable, while also can measure the fluid of high pressure; 7, flange and ring casing are cast as integrated, therebetween up-hole plate and pad, then are welded together by positive and negative ring casing, can enhance productivity and can accelerate installation rate.
