Abstract
The present invention relates to a vertical pipe with a downflow water flow static pressure cutting-off device, which belongs to the technical field of heating and air conditioning in buildings. The present invention has the technical scheme that certain of water flow quality is ensured in the vertical pipe, and the static pressure of the downflow water flow in the vertical pipe is eliminated simultaneously. The present invention can damage water check formed in the downflow water flow in the vertical pipe; a stabilize and effective air column is formed from top to bottom at the shaft center of the vertical pipe; thereby, the transfer of the static pressure of the downflow water flow in the vertical pipe is cut off, and the pressure oscillation at the bottom of the vertical pipe is eliminated. The present invention can realize that heating or air conditioning pipe networks in high zones can be directly connected with heating or air conditioning pipe networks in lower zones in high buildings, and can be used in other vertical pipes with the requirement of cutting off hydrostatic pressure.
Description
The invention belongs to standpipe current control technology, relate generally to the structure of downflow flowing static pressure cutting-off device in the standpipe.
The static pressure of current can be delivered to the bottom of standpipe by the pipeline current in the known standpipe.In order to cut off the static pressure of downflow flowing in the standpipe, conventional art adopts through the recovery tank overflow pipe and controls the way of the discharge in the standpipe, is desirably in and forms the moisture film fluidised form in the standpipe, makes that hydrostatic pressure is cut off in the standpipe.
So far as I know following document has argumentation in various degree to this.
[1]. Lu Yaoqing; " heating ventilator design manual "; Beijing.China Construction Industry Press.In December, 1987; The 335th page.
[2]. Lu Yaoqing; " practical heat supplying air conditioning design manual "; Beijing.China Construction Industry Press.In June, 1993; The 137th page.
[3]. TaiYuan Industry University etc.; " building plumbing system engineering "; New one edition; Beijing.China Construction Industry Press.In November, 1993; The 108th page.
[4]. Liu Mengzhen; Highrise building does not have the water tank system and inquires into; " HVAC "; (4) phase in 1997.The 26-29 page or leaf.
But when the used standpipe flow of existing Heating, Ventilation and Air Conditioning (HVAC) Technology (two water tanks, single recovery tank, exhaust cut-off device etc.) is big, The membrane flow mode instability of down-flow water causes the hydrostatic pressure fluctuation of riser bottom, and the heating effect in the low district of impact must not Often Jiang Gao district pipe network does not thoroughly separate in system with low district pipe network.
In document [3], introduced the research experiment situation of the water movement state in the soil stack, analyzed the fluidised form of water movement in soil stack and the Changing Pattern of pressure.Illustrated that the fluidised form of water is relevant with the factors such as geometric properties of the roughness of flow, water quality (contained amount of solid and viscosity in the water), tube wall, the water-filling rate of standpipe, the inlet of intaking, provided the flow when being the water film flow state in the standpipe, whole current limliting speed, the result of calculation of the design formulas of whole limit for length's degree and cast iron standpipe.The special standpipe of employing and horizontal arm connection fittings are arranged, with the interference that prevents and alleviate the current opposition periosteum stream that horizontal arm flows into and the trial of destruction in the existing living drainage system.But do not see having formed the solution of water plug in the standpipe.
The objective of the invention is to propose to have the standpipe structural concept of downflow flowing static pressure cutting-off device, make the interior flowing water down of standpipe form the moisture film motion state.
The object of the present invention is achieved like this, the standpipe that has downflow flowing static pressure cutting-off device, comprise the standpipe body, the standpipe that links is is with it imported and exported union end, be positioned at and leave the diversion component that is beneficial to circulation road under the water inlet that flowing water under the standpipe is the moisture film fluidised form and fixedly links between body inducer center and inboard wall of tube body with body, and the parts of the above-mentioned parts that are connected and fixed.Wherein, described diversion component is a tubular cylinder.Like this, water inlet is easy to form dirty membranaceous fluidised form under the effect of tubular cylinder diversion component, pressure free current moving; Purpose of the present invention is achieved.
Tubular cylinder of the present invention can be a solid cylinder, as Cylinder or multiedge cylinder; Also can be two sections pipeline sections that diameter is different that connect by reducer pipe; Can also be with standpipe in wall energy be maintained fixed spacing, have the shape tube on multiedge cylinder surface; Can resemble one " the inverted funnel of going up end closure " again, the upper end of this " funnel " or outer wall can connect a short tube, and its inner chamber is communicated with atmosphere, also can not connect.It is dirty that they all can make water be film stream shape along the inwall of standpipe and the passage between the diversion component outer wall, on the central axis of standpipe, form an air column naturally, guarantee that the air water border is orderly in the standpipe, controlled the fluidised form of water, make full use of the film circulation outlet capacity of standpipe.
The hypomere of standpipe of the present invention also is equipped with the U-shaped water sealing (sealing water) pipe, with assurance system logical atmosphere when superpressure and superpressure not when the return pipe net valve maloperation of low district.
The solution of the present invention can be realized by the apparatus structure of following four kinds of shapes respectively.
