Abstract
The utility model discloses a throttle ring device of a waste heat boiler, which comprises a throttle ring shell, wherein the throttle ring shell consists of a transverse pipeline and a straight pipeline which are communicated with each other; the front end of the transverse pipeline is communicated with a container; the internal wall of the transverse pipeline is provided with a position-limited platform on which a throttle ring with an opening at the middle part is arranged; the rear part of the throttle ring is provided with a fastening ring; the rear end of the transverse pipeline is provided with a plug cover which pushes the fastening ring firmly; the straight pipeline is communicated with the pipe wall of the transverse pipeline which is arranged at the rear part of the throttle ring; and the fastening ring is provided with an opening which is communicated with the straight pipeline. The throttle ring can be replaced and taken out of the transverse pipeline; when the boiler runs, the flux of each circuit under different working conditions is measured and recorded, the throttle ring is subsequently analyzed and designed; and when the throttle ring needs to be replaced, the boiler only needs to be stopped temporarily, the fixed device of the throttle ring is disassembled and a new throttle ring can be then assembled.
Description
Technical field
The utility model relates to a kind of waste heat boiler parts, specifically is the throttle device of waste heat boiler.
Background technology
In the waste heat boiler design, in order to guarantee that the waste heat energy in safe operation of the boiler and the flue gas effectively reclaims, the boiler endless form need adopt forced circulation, and the heating surface of a boiler needs promise to do a shunt circuit composition, the working medium flow that how to guarantee each loop satisfies the safe operation of the boiler requirement, need each loop flow is carried out reasonable distribution, each loop will be provided with the resistance coefficient that the different throttle of diameter is adjusted each closed circuit this moment.Traditional design is that throttle all is fixedly welded on tube interior, just can not change after its installation again.Can't regulate accurately the flow of each heating surface of boiler.Pipe must be severed as just changing, retube again and throttle, very trouble.
Summary of the invention
The purpose of this utility model provides a kind of throttle device of waste heat boiler, when needs are regulated throttle, pipe need not be severed, and directly takes out the throttle replacing from the throttle housing and gets final product, and is very convenient.
The technical solution of the utility model is as follows:
A kind of throttle device of waste heat boiler, it is characterized in that: include the throttle housing, described throttle housing is made up of the horizontal pipe and the straight length of mutual UNICOM, described horizontal segment front end and collection case UNICOM, described horizontal segment inwall has limiting stand, the throttle of perforate in the middle of being equipped with on the described limiting stand, be placed with dead ring behind the throttle, described horizontal segment rear end is equipped with gag and holds out against dead ring, the horizontal segment tube wall UNICOM at described straight length and throttle rear has perforate to communicate with straight length on the described dead ring.
Described throttle device is characterized in that: described gag is a fastening bolt, and described firm bolt is threaded with the horizontal segment rear end, between fastening bolt and the dead ring gasket seal is arranged.
Throttle of the present utility model can take out, change from horizontal segment, has thoroughly solved this and has perplexed the difficult problem of waste heat boiler design and use for a long time, is the inside that throttle is fixed on the horizontal segment pipe by hold down gag.When boiler operatiopn, earlier the flow in each loop under the different operating modes is measured and record, then throttle is analyzed design, as need change throttle only need of short duration blowing out just the throttle fixture unload, load onto new throttle again and get final product.
Description of drawings
The utility model is described in more detail below in conjunction with drawings and embodiments.
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Referring to accompanying drawing.
A kind of throttle device of waste heat boiler, include the throttle housing, described throttle housing 2 is made up of the horizontal pipe and the straight length of mutual UNICOM, described horizontal segment front end and collection case 1 UNICOM, described horizontal segment inwall has limiting stand, the throttle 3 of perforate in the middle of being equipped with on the described limiting stand, be placed with dead ring 4 behind the throttle 3, described horizontal segment rear end is equipped with fastening bolt 6 and holds out against dead ring 4, between firm ring 4 and the fastening bolt gasket seal 5 is arranged, the horizontal segment tube wall UNICOM at straight length and throttle 3 rears has perforate to communicate with straight length on the described dead ring 4.
Claims (2)
1. the throttle device of a waste heat boiler, it is characterized in that: include the throttle housing, described throttle housing is made up of the horizontal pipe and the straight length of mutual UNICOM, described horizontal segment front end and collection case UNICOM, described horizontal segment inwall has limiting stand, the throttle of perforate in the middle of being equipped with on the described limiting stand, be placed with dead ring behind the throttle, described horizontal segment rear end is equipped with gag and holds out against dead ring, the horizontal segment tube wall UNICOM at described straight length and throttle rear has perforate to communicate with straight length on the described dead ring.
