Abstract
The utility model relates to a separated type elbow pipe flow meter, which belongs to a flow metering device. The utility model is composed of upper and lower elbow pipe sensors, thread connecting parts and two flanges, the upper and lower elbow pipe sensors are connected oppositely and fixed together through screws, ends of the two connecting parts are respectively welded with the two flanges, the other ends are respectively connected with the both ends of the two elbow pipe sensors through a conical pipe thread, and sealing rings are arranged on the connection surface of the upper and lower elbow pipe sensors and on the connection surface of a thread connecting part and the upper and lower elbow pipe sensors. After being arranged on the process pipe line through flanges, the disassembly and assemble of the utility model are easy, being convenient for the measurement of the inner surface geometric parameter through traditional measuring tools to make accurate measurement, and convenient for the regular removal of the inside fouling such as silicate, and guaranteeing the long-term, steady and reliable running of the flow meter.
Description
Technical field
The utility model relates to a kind of flow measurement device, refers in particular to a kind of split type elbowmeter.
Background technology
Elbowmeter is a kind of novel flow instrument, and its most crucial part is the primary element that is called Bending Tube Sensor.Original primary element all is whole, is welded in behind the process pipeline not removablely, and fouling that long-time running caused and booty are piled up the influence of flowmeter measuring accuracy very important.The geometric parameter of primary element inside surface and precision are to cause the major reason of error in dipping.The geometric parameter of the Bending Tube Sensor inside surface of former integral body can only be by the geometric parameter of outside surface, artificially considers the thickness of foul accumulation horizons such as wall thickness and fouling and obtains indirectly, is subjected to many condition restriction (as evenness of wall thickness etc.) and is difficult to reach promising result.
Summary of the invention
The purpose of this utility model provides a kind of split type Bending Tube Sensor of detachable one-tenth separate unit, so that the geometric parameter of its inside surface is detected and makes accurate measurement by traditional appliance, regularly remove inner foulings such as silicate, long-term, the stable and operation reliably of dependable flow meter.
Technical solution adopted in the utility model is: a kind of split type elbowmeter, constituted by last Bending Tube Sensor 1, following Bending Tube Sensor 2, threaded connector 4 and ring flange 5, Bending Tube Sensor 1 and following Bending Tube Sensor 2 butt joint backs are fixed together by an attachment screw 3 on it, one end of two threaded connectors 4 welds together with two ring flanges 5 respectively, and the other end is the two ends bolt by taper-thread and two Bending Tube Sensors respectively.
On the joint face of last Bending Tube Sensor 1 and following Bending Tube Sensor 2 O-ring seal is installed, on the joint face of threaded connector 4 and upper and lower Bending Tube Sensor 1,2 the O RunddichtringO is installed, to guarantee its sealing property.
The beneficial effects of the utility model are: because Bending Tube Sensor is taked upper and lower two docking modes, its two ends are earlier by threaded connector and ring flange welding, by ring flange Bending Tube Sensor is installed on process pipeline again, make its partition and assembling easily, be convenient to the geometric parameter of its inside surface be detected and make accurate measurement by traditional appliance, regularly remove inner foulings such as silicate, long-term, the stable and operation reliably of dependable flow meter.Owing to O-ring seal is installed, make its good seal performance again at the joint face of upper and lower Bending Tube Sensor and the joint face of threaded connector and upper and lower Bending Tube Sensor.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is done to describe in further detail.
As shown in Figure 1 and Figure 2, a kind of split type elbowmeter, constituted by last Bending Tube Sensor 1, following Bending Tube Sensor 2, threaded connector 4 and ring flange 5, Bending Tube Sensor 1 and following Bending Tube Sensor 2 butt joint backs are fixed together by an attachment screw 3 on it, one end of two threaded connectors 4 welds together with two ring flanges 5 respectively, and the other end is the two ends bolt by taper-thread and two Bending Tube Sensors respectively.
In order to guarantee sealing, on the joint face of last Bending Tube Sensor 1 and following Bending Tube Sensor 2 O-ring seal is installed, on the joint face of threaded connector 4 and upper and lower Bending Tube Sensor 1,2 the O RunddichtringO is installed.
Because convenient partition of the utility model and assembling, expanded the application of elbowmeter greatly, reduced the degree of purity requirement of elbowmeter to measuring media, improved the interchangeability of elbowmeter, can guarantee that elbowmeter reuses under high precision and prolonged serviceable life, it has a extensive future.
