Abstract
The utility model relates to a detachable water distribution flow equalization device, which is characterized in that a pipe connection connected with a heat exchange pipe is installed in an inlet heater; a flow equalization pipe on which a plurality of small holes are formed is connected to the port of the pipe connection; an overhaul hand-hole is formed on a header cylinder body corresponding tothe flow equalization pipe; the length of the flow equalization pipe exceeds that of the cylinder body wall of the corresponding overhaul hand-hole; the end part of the flow equalization pipe and thepipe connection are in threaded connection; and the other end of the flow equalization pipe is a closed end provided with a connector suitable for being screwed on a sleeve. The utility model can effectively avoid the heat exchange pipe damage due to insufficient cooling; and when the device is demounted or overhauled, the overhaul hand-hole is opened, and the flow equalization pipe is removed through using the matched sleeve to unscrew a thread, therefore, the use is convenient; and the flow equalization pipe can still be taken out even when sunk into the heater.
Description
Technical field
The utility model relates to the heat energy utilization technology, relates in particular to the current equalizer of boiler or heat exchanger.
Background technology
Boiler or heat exchange equipment feedwater (recirculated water) are limit by the equipment self structure, may there be same heat exchange structure local supply (recirculated water) mass flow discrepancy, thereby cause the part heat exchanger tube to damage, both influenced the normal operation of equipment, cause certain potential safety hazard again because of cooling off inadequately.
The current equalizer of prior art adopts fixedly usually, and shortcoming is dismounting and the maintenance that is unfavorable for current equalizer.The detachable current equalizer of employing is also arranged, but often exist suitable operating pressure lower, current equalizer sinks into can't take out in the inlet header case easily when operate miss takes place, thereby causes new potential safety hazard.
Summary of the invention
The utility model main purpose is: overcome the deficiencies in the prior art, thereby develop a kind of detachable current equalizer easy to maintenance.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: detachable moisture is joined current equalizer, it is characterized in that: the pipe joint that connects heat exchanger tube is housed in the inlet header case, port at pipe joint connects the current-sharing pipe that has a plurality of apertures, has the maintenance hand hole on the corresponding collection case of current-sharing pipe cylindrical shell; The length of described current-sharing pipe surpasses the barrel wall of corresponding maintenance hand hole.
The technical solution of the utility model can also be further perfect, as preferably, adopts between the end of described current-sharing pipe and the pipe joint to be threaded, and the other end of current-sharing pipe is a blind end, and described blind end is provided with and is suitable for the connector that sleeve is screwed.
Therefore, the beneficial effects of the utility model are: the current-sharing effect is fairly obvious, can prevent effectively that heat exchanger tube is because of cooling off the destruction of causing inadequately.When dismounting or maintenance, open the maintenance hand hole, unscrew with supporting sleeve pipe and can take out current equalizer, easy to use.Because the current-sharing length of tube is longer, and entered collection case cylindrical shell position, so when dismounting, it is interior and can't take out that current-sharing Guan Buhui is absorbed in the collection case.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
The specific embodiment
Below by embodiment also in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment:
Detachable current equalizer as shown in Figure 1, by inlet header case 1, the import header pipe joint 2 that is used to connect heat exchanger tube is housed on the inlet header case, adopt welding between pipe joint and the inlet header case, entrance point at pipe joint 2 is equipped with current-sharing pipe 3, current-sharing Guan Weiyi end links to each other with pipe joint that the other end seals, have the tube connector of a plurality of apertures on the tube wall, blind end is provided with and is suitable for the connector 5 that sleeve is screwed, current-sharing pipe 3 adopts with pipe joint and is threaded, on current-sharing pipe 3 corresponding collection case cylindrical shells, have maintenance hand hole 4, in working order maintenance hand hole sealing down.The length of current-sharing pipe surpasses the barrel wall of corresponding maintenance hand hole.After feedwater (recirculated water) enters the inlet header case, enter heat exchanger tube through pipe joint, thereby the exchange heat pipe plays the current-sharing effect by current equalizer.
When dismounting or maintenance, open the maintenance hand hole, entangle connector 5, unscrew the screw thread of current-sharing pipe 3, can take out the current-sharing pipe with supporting sleeve.Because the current-sharing length of tube is longer, and entered collection case cylindrical shell position, so when dismounting current-sharing pipe, it is interior and can't take out that current-sharing Guan Buhui is absorbed in the collection case.
The utility model can be widely used in all kinds of boilers or heat exchange equipment.
