Abstract
The invention relates to a steam integral balance flow meter. The steam integral balance flow meter comprises a sensor body, a bracket, a differential pressure transmitter, a pressure-leading short tube, a three-valve manifold, a root valve and a cooling tube, wherein a porous disk throttle rectifier is arranged in the sensor body; the sensor body is provided with a pressure-leading hole which is communicated with the porous disk throttle rectifier; the differential pressure transmitter is fixed to the sensor body through the bracket; one end of the cooling tube is connected with the differential pressure transmitter through the three-valve manifold, and the other end of the cooling tube is connected with one end of the root valve through a choke plug; and the other end of the root valve is connected with the pressure-leading hole through the pressure-leading short tube. The steam integral balance flow meter has the advantages that the measurable degree of the steam integral balance flow meter is higher than that of the common balance flow meter, the damage to the differential pressure transmitter caused by long-term measurement of high-temperature steam is greatly reduced, the safe use of throttling elements is ensured, the service life of the meter is prolonged, and the measurement and the measurement accuracy of flow low-range ends are ensured.
Description
Technical field
The present invention relates to a kind of flowmeter, particularly disclose a kind of steam integration balance flow meter.
Background technology
Steam is the most widely used heat-carrying working medium, is important secondary energy.Along with the quickening of social development and process of industrialization, the measurement of steam flow has a large capacity and a wide range, and guarantees the accurate measurement of steam flow, all significant to the strengthening management of steam, fair trade, energy savings, the aspect such as increase economic efficiency.Measure the steam of high temperature, if being equipped with differential pressure transmitter as common balance flow meter then can not work under hot conditions for a long time, because the maximum temperature that differential pressure transmitter can bear generally is no more than 130 ℃, and this a kind of special media of steam, it self temperature all will be higher than 130 ℃, does not make steam directly by differential pressure transmitter, if work under hot conditions for a long time if do not add any protection, be certain to damage differential pressure transmitter, the normal production of impact measured; Between sensor body and differential pressure transmitter, install drainer additional, though can solve the problem that common balance flow meter can not at high temperature be worked for a long time like this, its mounting structure is huge, if in narrow space, installs being inconvenient to.
Summary of the invention
The object of the invention is to overcome the defective that exists in the prior art, a kind of degree of measurement height is provided, improves serviceable life, guarantees the steam integration balance flow meter of measuring accuracy.
The present invention is achieved in that a kind of steam integration balance flow meter, establish the sensor body of porous disc throttling rectifier in comprising, support, differential pressure transmitter, the impulse short tube, three valve groups, root valve, described sensor body is provided with the tracting pressuring hole that is connected with porous disc throttling rectifier, it is characterized in that: also comprise cooling tube, described differential pressure transmitter is fixed on the sensor body by support, one end of described cooling tube links to each other with described differential pressure transmitter by three valve groups, the other end of described cooling tube is by silently linking to each other with described root valve one end, and the described root valve other end links to each other with described tracting pressuring hole by the impulse short tube.
The angle of described impulse short tube place axis and described support place axis is at 45 ° or 60 °.
Described support place axis is mutually vertical with described cooling tube place axis.
Be provided with the impulse bend pipe between the silently described and root valve.
The invention has the beneficial effects as follows: it is can degree of measurement higher than common balance flow meter aspect vapour survey; the damage that when greatly having reduced long-term measurement high-temperature steam differential pressure transmitter has been caused; this is because dispose cooling tube before steam enters differential pressure transmitter; be equivalent to traditional condenser; the cooling tube top has one silently; during installation; close first root valve; turn on silently and afterwards cooling tube is filled water; this has just played the effect of protection restricting element; improve the serviceable life of instrument error pressure transmitter, also guaranteed at high temperature for a long time demand of security measurement simultaneously.
