Abstract
The utility model discloses finned heat exchanger drainage elbows.Heat exchanger elbow arrange limitation or user's operation it is improper etc. due to, cause bottom part copper pipe elbow internal drainage not clean.Remaining moisture, which freezes, when environment temperature is too low, in heat exchanger copper pipe is then easiest to the exposed elbow outside of bursting by freezing to influence the service life of unit.To overcome this drawback, drainage elbow is installed in finned heat exchanger water easy-storing position, thoroughly empties residual moisture.This solves finned heat exchangers to drain not clean problem, avoid winter often freezing elbow the case where occur, it has very positive realistic meaning to the normal use of finned heat exchanger.
Description
Technical field
The utility model is related to air-conditioning equipment accessories, and in particular to a kind of finned heat exchanger drainage elbow.
Background technology
With the development of economy, requirement of the mankind to living environment is higher and higher, to the quality of air-conditioning increasingly pay close attention to
Pay attention to.As the essential core component finned heat exchanger of central air conditioner system end prod, pass through circulating water or hot water
It exchanges heat with air, provides required temperature and humidity environment to the user.It is applied to office building, market more and more widely
Etc. the place for needing progress air conditioning.
But for cold and severe cold area, when winter compressor emergency shutdown, maintenance etc. need finned heat exchanger to drain, by
It arranges limitation or the reasons such as user's operation is improper in heat exchanger elbow, causes part copper pipe bend internal drainage not clean.If environment
Temperature is too low, and remaining moisture, which freezes, in heat exchanger copper pipe is then easiest to the exposed elbow outside of bursting by freezing, to influence user
It uses.
Invention content
To solve the above-mentioned problems, the utility model provides a kind of finned heat exchanger drainage elbow, and being easily installed makes
With, it is ensured that water, draining be not thoroughly clean for the arbitrary pipeline of heat exchanger.The technical solution adopted in the utility model is as follows：
A kind of finned heat exchanger drainage elbow, it is characterised in that：Including straight sections and bent portion, the tail of the straight sections
Portion is connected with needle-valve, and the needle-valve is connect with heat exchanger drainpipe when discharging water；
Bent portion branch since the intermediate position of straight sections is bent so that drainage elbow is in integrally H-shaped.
Above-mentioned finned heat exchanger drainage elbow, the centre-to-centre spacing between the straight sections nozzle and bent portion nozzle are straight tube
The length of 2.5-2.8 times of portion's caliber, the straight sections is 30-55mm.
The beneficial effects of the utility model are：Which is simple in structure, and control program is easy to implement, and needle-valve can be realized and be changed
The slowly varying guarantee flow of pressure in hot device is continuous, and bent portion structure smoothly greatly avoids ponding, the knot of the utility model
Structure solve the problems, such as heat exchanger draining be not thorough, drainage joint it is easily freezing.
Description of the drawings
Fig. 1 is the dimensional structure diagram of the utility model；
Fig. 2 is the positive structure diagram of the utility model；
In figure：1 it is needle-valve, 2 be bent portion, 3 is straight sections.
Specific implementation mode
The utility model is further explained below in conjunction with the accompanying drawings.
The present embodiment is a kind of finned heat exchanger drainage elbow comprising straight sections 3 and bent portion 2, the straight sections 3
Tail portion be connected with needle-valve 1, the needle-valve 1 is connect with heat exchanger drainpipe when discharging water, even if so design be directed to different size
Heat exchanger only need to change needle-valve 1 i.e. can be used, it is very convenient.The bent portion 2 is since the intermediate position of straight sections 3
Branch is bent so that drainage elbow is in integrally H-shaped.
Above-mentioned finned heat exchanger drainage elbow, the centre-to-centre spacing between 2 nozzle of 3 nozzle of the straight sections and bent portion is straight
The length of 2.5-2.8 times of 3 caliber of pipe portion, the straight sections 3 is preferably 35mm.Preferably, in the present embodiment, straight sections 3
The caliber of nozzle and bent portion 2 is 10mm, between centre-to-centre spacing be 25mm.
Claims (2)
