The direct-connection heating and return water pressure stabilizing device is characterized in that the water inlet pipe and the water outlet pipe are coaxially arranged, the water outlet pipe penetrates through the expansion bin and is installed on the expansion bin in an inserting mode, and a taper-shaped end cap is fixedly installed at the upper end of the water outlet pipe; the upper end of the expansion bin is fixedly connected with a casing pipe, the casing pipe is a threaded pipe with a spiral groove formed in the inner wall, the lower end of the casing pipe is installed in the upper bin wall of the expansion bin in an inserting mode, an end cover is fixedly installed at the upper end of the casing pipe, the water inlet pipe is installed on the end cover in an inserting mode, and the water inlet pipe and the casing pipe are coaxially arranged; a plurality of penetrating holes are formed in the pipe wall of the water outlet pipe located in an inner cavity of the expansion bin or an inner cavity of the casing pipe. The direct-connection heating and return water pressure stabilizing device well solves the problem of high-rise return water decompression in a direction-connection heating system of a high-rise building, when decompression is carried out, a water current is stable, a stable partly-filled pipe flow state can be formed, operation noise is low, pressure fluctuation is small and gas is not carried.
Description
Technical field
The utility model relates to a kind of high-rise heating equipment, is a kind of direct connection heating backwater stable-pressure device specifically.
Background technology
The heating demand in existing high district also has low district's heating demand in the high rise building heating system, in order to take into account the heating in high district, low district, adopts following several structure usually, and the high district of the first and low district adopt the separate heating system of two covers respectively.High district heating system has higher pressure, so that hot water arrives the room of eminence, and then refluxes; Low district heating system then adopts lower pressure, in order to avoid high pressure damages radiator.The method of this district heating though can satisfy the requirement of high low area heating, needs to build two cover heating systems, and equipment investment is big, the operation and maintenance cost height.The way that another kind is comparatively economic is that low district's heating system and thermal source is direct-connected, and high the district established pump pressurization heating, incorporates in the return pipe in low district after the backwater process water tank decompression in high district again.Though this scheme is comparatively economical, need place two attemperaters at high building, the repeatedly turnover in water tank of supplying water, thermal losses is bigger, and waste is serious, and the water level in the water tank is difficult to control, also makes troubles to operational management.Chinese patent 97230200 " skyscraper does not have the exhaust cut-off device of water tank direct connection heating " provides the third solution, force (forcing) pump will be given high district after will hanging down the hot water pressurization in district, height district backwater after the radiator heat release enters the pressure release of exhaust cut-off device, returns in the low district water return pipeline with the partly-filled pipe-flow form then.This scheme need not to arrange high-rise water tank, has reduced construction costs, also can reduce thermal losses.But problems such as because the defective in the exhaust cut-off device design, ubiquity spilling water, operation noise are big, non-full pipe fluidised form shakiness, return pipe pressure oscillation, and the use of these exhaust cut-off devices makes gas sneak into the thermal source pipe network easily, influences heating effect.
Summary of the invention
The purpose of this utility model is to overcome the defective that above-mentioned prior art exists, and provides a kind of and can form stable non-full pipe fluidised form, moves the direct connection heating backwater stable-pressure device that noise is little, pressure oscillation is little, not gas-entrained.
For achieving the above object, the utility model is by the following technical solutions:
Direct connection heating backwater stable-pressure device described in the utility model comprises water inlet pipe, outlet pipe, is arranged on the expansion storehouse between water inlet pipe and the outlet pipe, it is characterized in that: the coaxial setting of described water inlet pipe and outlet pipe, outlet pipe runs through and is inserted on the expansion storehouse, and the upper end of outlet pipe is installed with the taper end cap; The upper end fixed connecting sleeve in expansion storehouse, described sleeve pipe are that inwall has the spiral fluted screwed pipe, and the lower end of sleeve pipe is inserted in the last bulkhead in expansion storehouse, and the upper end of sleeve pipe is installed with end cap, water inlet pipe be inserted on the end cap and with the coaxial setting of sleeve pipe; The tube wall that is arranged in the outlet pipe of expansion storehouse inner chamber or cannula cavity is provided with a plurality of through holes.
Be fitted with respiratory siphon on the described end cap.
The tube wall of described outlet pipe is provided with helicla flute.
After adopting technique scheme, this direct connection heating backwater stable-pressure device has solved the problem of direct connection heating system for high-rise building backwater pressure release on the middle and senior level well, waterflow stabilization during pressure release, can form stable non-full pipe fluidised form, the operation noise is little, pressure oscillation is little, not gas-entrained.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model.
The specific embodiment
The utility model will be further described below in conjunction with the drawings and specific embodiments.
As shown in drawings, direct connection heating backwater stable-pressure device described in the utility model comprises water inlet pipe 1, outlet pipe 2, is arranged on the expansion storehouse 3 between water inlet pipe 1 and the outlet pipe 2, described water inlet pipe 1 and outlet pipe 2 coaxial settings, outlet pipe 2 runs through and is inserted on the expansion storehouse 3, and the upper end of outlet pipe 2 is installed with taper end cap 4; The upper end fixed connecting sleeve 5 in expansion storehouse 3, described sleeve pipe 5 is that inwall has the spiral fluted screwed pipe, the lower end of sleeve pipe 5 is inserted in the last bulkhead in expansion storehouse 3, the upper end of sleeve pipe 5 is installed with end cap 6, water inlet pipe 1 be inserted on the end cap 6 and with sleeve pipe 5 coaxial settings, also be fitted with respiratory siphon 8 on the described end cap 6.The tube wall that is arranged in the outlet pipe 2 of expansion storehouse 3 inner chambers or sleeve pipe 5 inner chambers is provided with a plurality of through holes 7.
In addition, as another embodiment of the present utility model, in order to obtain better water conservancy diversion erasure effect, the tube wall of described outlet pipe 2 is provided with helicla flute.
During use, water inlet pipe 1 is connected to the return pipe of high-rise radiator, outlet pipe 2 is connected to the return pipe of low layer radiator.The backwater of high-rise radiator elevated pressures enters after the water inlet pipe 1, broken up by taper end cap 4, the water impact that scatters is to the inwall of sleeve pipe 5, helicla flute rotation along sleeve pipe 5 inwalls descends, form whirlpool shape descent waterflow, the current that descend enter after the expansion storehouse 3, the space sudden enlargement, the pressure of current is released, hydraulic pressure reduces, will enter in the inner chamber of outlet pipe 2 by the through hole 7 on the outlet pipe 2 after water level in the expansion storehouse 3 reach a certain height, finally incorporate in the low layer return water system by outlet pipe 2.
