Background technique
Supporting heating system in high-rise building, generally comprise low district (low pressure) heating system of promising low layer resident family heating and be height district (high pressure) heating system of high-rise buildings heating, and the return water system of high district heating system is that to carry out step-down direct-connected by being arranged on cistern free and the low return water system of distinguishing heating system in tall building at present mostly.And the cistern free direct connection heating system on tall building belongs to open system, communicate with atmosphere, thus all there is more serious oxidation corrosion situation in e-quipment and pipe of heating system etc., thereby be not suitable for promoting the use of.
Disclose a kind ofly be used to carrying out the direct-connected variable flow pressure control device of high low area heating system step-down in Chinese patent database, its structure includes main casing, upper cover, sealing cap, piston plate, regulator plate, Regulation spring, adjusting guide rod, opens and closes spring and sealing drum etc.This variable flow pressure control device is to utilize waterpower self-characteristic, employing mechanical device to realize current recloser and automatic reducing pressure stabilizing operation forward.But find in actual use; this variable flow pressure control device exists a more serious problem to turn-off exactly difficulty; this be because the backwater of high district heating system the jet of gushing from the water intake of main casing one side to the straight-through water outlet mouth of opposite side (communicating with low district heating system) can the baffle seal cylinder smooth decline; make variable flow pressure control device can not implement effective shutoff; can not cut off high district and low sound zone system, cause the pressure of low district heating system after shutting down constantly to raise.
The model utility content
The purpose of this utility model just is to provide a kind of height nip pressure regulation straight-through device, with the step-down direct connection device that solves existing high low area heating system can not reliable turn-off problem.
the utility model is achieved in that a kind of height nip pressure regulation straight-through device, upper, be provided with the abdomen dividing plate in the housing of under shed, described housing is divided into the zone of high pressure that joins with height district heating system and the low pressure area that joins with low district heating system, have the pressure release cone mouth that is communicated with described zone of high pressure and described low pressure area on described abdomen dividing plate, be provided with the pressure regulation cone blocking of controlling openings of sizes in described pressure release cone mouth, lower end in described pressure regulation cone blocking is connected to connecting rod, the lower end of the described connecting rod plug of taking over a job, described piston is arranged in the lower end cap inner chamber that joins with described housing end opening, being connected in the bottom of described lower end cap can be to the lower driving interface of water filling in lower end cap, upper end in described pressure regulation cone blocking is connected to locating column, the abutment sleeve that is connected to suitable for reading at described housing, the upper end of described locating column is stretched in the lower end mouth of described abutment sleeve, cross-under has the adjusting screw rod that limits described locating column lifting height in described abutment sleeve, be provided with Returnning spring in described abutment sleeve, the lower end of the described Returnning spring described locating column of socket also leans upper-end surface in described pressure regulation cone blocking.
Be provided with the ring cowling that the described pressure release cone mouth of capping is used on described pressure regulation cone blocking.
Upper end at described abutment sleeve is sealed with upper end cap.
Have water intake on the described housing sidewall of described zone of high pressure, have water outlet on the described housing sidewall of described low pressure area.
The utility model is communicated with zone of high pressure and low pressure area by the pressure release cone mouth on housing abdomen dividing plate, and the backwater of high district heating system is effectively reduced pressure by the jet in the pressure release cone mouth; Simultaneously, by adjusting the height of adjusting screw rod, the raising height of pressure regulation cone blocking is adjusted, adjusted thus the openings of sizes of pressure release cone mouth, thereby reach the purpose of adjusting the jet flow size.When heating system has a power failure, by pressing down of Returnning spring and high pressure water, make the shutoff of pressure regulation cone blocking on the pressure release cone mouth, realize that the shutoff formula seals firmly; When restoring electricity, the heating water of pumping, lifts the pressure regulation cone blocking with piston jack-up by lower driving mouth, automatically opens the pressure release cone mouth, recovers the direct-connected work of jet decompression of normal height nip.
The utility model utilizes the hard sealing of pressure regulation cone blocking on the pressure release cone mouth, and the step-down direct connection device of height nip is turn-offed firmly, turn-offs reliable in action, and decompression is adjusted convenient, can satisfy the use needs of various tall buildings.The utility model can be widely used in large mountain area heating system and all variable flow systems, constant flow water system, closed system and the deaerating type of cycles etc. of heating system, air-conditioner water system, the ground discrepancy in elevation of tall building.
