Abstract

The utility model relates to a high-level heating backwater buffering and air exhausting device, which comprises a buffer, a non-return air exhausting valve, and an air separator. The utility model has the structure that a butterfly valve connected with a horizontal water return pipe is arranged on the inlet side of the buffer, and the upper part of the buffer is provided with the non-return air exhausting valve; a vertical water return pipe is arranged between the bottom of the buffer and the upper part of the air separator through a flange, the upper part of the buffer and the top of an air collecting channel in the air separator are connected with an air exhausting connecting pipe, and the outlet opening at the bottom of the air separator is connected with a water return main pipe through a flange. The utility model is arranged on a section of vertical water return pipeline between the highest level return point of a high-level heating system and the position 2 meter being lower than a water return kinetic pressure line. The structure is simple, the running is reliable and the thermal efficiency is high.

Description

High-rise heating water return buffering exhaust apparatus

The utility model relates to a kind of turn back a little backwater buffering exhaust apparatus to one section vertical return pipe between following 2 meters of the backwater dynamic pressure line of Heating System of High Residential Buildings highest order that is installed on.

The Heating System of High Residential Buildings that has in the prior art is provided with pressure-reducing valve, because the movable parts of pressure-reducing valve internal mechanism unavoidably are subjected to the erosion of heat medium water, initiating system fault and heating accident happen occasionally because impurity silts up.Have, the high-rise heating of heating of existing pair of water tank high level and cutout all is top unlatchings, directly contacts with atmosphere, has caused system's oxygen candle problem again, and the high-rise thermal efficiency that heats of heat exchanger is low in addition, loss is insoluble problem greatly always.

The purpose of this utility model is at existing some shortcomings in the existing Heating System of High Residential Buildings, and has designed a kind of high-rise heating water return buffering exhaust apparatus of open and close check air bleeding valve automatically that has in current heating systems.

For achieving the above object, the utility model has adopted following technical scheme: high-rise heating water return buffering exhaust apparatus comprises buffer (1), check air bleeding valve (2) and steam separator (3), its concrete structure is: import one side of buffer (1) is provided with butterfly valve (6) and links to each other with horizontal return pipe, and the top of buffer (1) is provided with check air bleeding valve (2); Link by flange (7) and vertically arranged return pipe (4) between the top of bottom and steam separator (3), gas skirt 13 tops in the top of buffer (1) and the steam separator (3) are connected with exhaust cross over pipe (5), and the outlet bottom the steam separator (3) is passed through flange (7) and linked to each other with the backwater main.

Characteristics of the present utility model are: (1) is with the relief valves designs that adopts in the existing system, change into and have the backwater buffering exhaust apparatus of the check air bleeding valve of open and close automatically, it is reliable, has avoided because impurity silts up and the generation of initiating system fault and heating accident.(2) operating thermal efficiency height, this device directly utilize the heat medium water heating of heat supply network, the additional heat loss in efficiency of having avoided Heating System of High Residential Buildings to adopt thermal converter to bring.(3) discharge of the gas of this device is to discharge system via automatic open and close non-return valve, has overcome in the prior art directly to contact system's oxygen candle problem of being brought with atmosphere.(4) key technical problem of this device is, because when the pressure of the gas of discharging in water and flow are very little, the performance of non-return valve will reach to close wants sternly, opens to press and want little requirement, for check exhaust valve opening pressure accurate, close tight reliable, the check air bleeding valve made can be conveniently from the buffer field-strip and can independent pressure testing.This device simplicity of design, easy for installation, safe and reliable to operation, be suitable in current heating systems, installing and using.

Below in conjunction with specific embodiment and accompanying drawing the utility model is further described.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the cutaway view of check air bleeding valve among Fig. 1.

Fig. 3 is the vertical view of Fig. 2 middle valve plate and rubber cushion.

Fig. 4 is the cutaway view of steam separator among Fig. 1.

With reference to Fig. 1,4, high-rise heating water return buffering exhaust apparatus comprises buffer 1, check air bleeding valve 2 and steam separator 3, and its concrete structure is: import one side of buffer 1 is provided with butterfly valve 6 and links to each other with horizontal return pipe, and the top of buffer 1 is provided with check air bleeding valve 2; Link by flange 7 and vertically arranged return pipe (4) between bottom and the top of steam separator 3, the top of buffer 1 and steam separator 3 interior gas skirt 13 tops are connected with exhaust cross over pipe 5, and the outlet of steam separator 3 bottoms is passed through flange 7 and linked to each other with the backwater main.

With reference to Fig. 2,3, check air bleeding valve 2 mainly is made of with rubber cushion 12 upper valve body, following valve body and valve block 9, be provided with seal gasket 12 below the valve block 9, screw 11 is fixed on down seal gasket 12 1 ends on the valve body, upper valve body is fixing by bolt 10 with following valve body, and the exhaust outlet of check air bleeding valve 2 also is provided with dust cap 8.

This device is installed by system's last time (backwater is last), and it is particularly suitable for directly connecting with the journey heating system with " household heating ".This device is installed in turning back a little to one section vertical return pipe between following 2 meters of the backwater dynamic pressure line of system's highest order.Horizontal return pipe is installed by tangential angle at peak and buffer top cylinder inwall, makes the backwater current do centrifugal rotational flow along the buffer inwall after flowing into buffer.When the backwater current under the self gravitation effect, drop to cone and the second line of a couplet return pipe part after, will quicken centrifugal rotation more.The backwater current are exactly to lean on to finish the buffer deceleration process with interior wall friction in this centrifugal rotation, have also partly finished the course of work of gas-water separation simultaneously.For thoroughly finishing gas-water separation, this device is equipped with steam separator under backwater dynamic pressure line, one vertical gas skirt is set in the centre of steam separator, force current dirty along tube wall, in the time of near current arrive near the steam separator bottom, current have elder generation laterally to change the mobile steering procedure of the water that changes again downwards, and the gas that floats along tube hub in gas of shaking off out in this course and the second line of a couplet return pipe all compiles in the gas skirt at steam separator center.The gas reusing cross over pipe that is pooled to the gas skirt top is concentrated this part gas buffer upward, again by the check air bleeding valve above the buffer to airborne release.
