Background technique
Present most of central heating system all exists assignment of traffic uneven basically, causes the not hot problem of part heating system.The problem not hot for heating system adopts following two kinds of measures at present: the one, because heating area is larger, heating pipe is long, heat range of heat is larger, the architecture heating system near apart from thermal source supplies, backwater pressure reduction is large, flow velocity is fast, room temperature is higher, the architecture heating system far away apart from thermal source supplies, backwater pressure reduction is little, flow velocity is slow, room temperature is lower, and a lot of heating plants are not heat problem of understanding system, and systemic circulation pump duty and Yang Cheng are strengthened, the result causes the operation power consumption to strengthen, and pipeline and radiator booster, quick-fried accident appear in system.The 2nd, adopt artificial regulative mode, close the near heating system backwater of narrow spacing thermal source and come the regulating system flow equilibrium.Generally speaking this dual mode is all undesirable, is difficult to realize that each regional flow of heating system and the rationalization of pressure reduction distribute.
The model utility content
Technical problem to be solved in the utility model provides a kind ofly can regulate each regional system flow automatically according to return water temperature, to satisfy each regional flow equilibrium of large-scale heating system, make the self-supporting temperature-sensing valve of the identical heating special use of each heating zone supply water temperature.
Adopt following technological scheme for solving technical problem of the present utility model:
A kind of self-supporting temperature-sensing valve comprises main valve, and a hydraulic control valve is established in described main valve upper end, and the main valve lower end connects outlet pipe, and a type liquid expansion temperature controller is set on the described outlet pipe, and described type liquid expansion temperature controller is connected with the hydraulic control valve pipeline.
Establish a piston brace rod in the described main valve, a rise pole is established in described piston brace rod upper end, a lower dolly bar is established in the lower end, establish a large piston on the described piston brace rod, establish a small piston between piston brace rod and the lower dolly bar, between small piston and the valve body lower cover spring is housed.
Described hydraulic control valve is established a housing, described housing is provided with water intake and water outlet, establish an adjustable lever in the described housing, described adjustable lever is provided with adjustment hole, described housing one end is established an end cap, described adjustable lever one end passes end cap, and the other end is connected with the piston of oil hydraulic cylinder, and described adjustable lever passes on the end of end cap and is set with elastic member.
Described type liquid expansion temperature controller is provided with housing, in the described housing swelling liquid is housed, and the outlet pipe of described main valve passes housing.
The housing of described type liquid expansion temperature controller is provided with thermometer and pressure gauge.
The utility model is comprised of main valve, hydraulic control valve, type liquid expansion temperature controller three parts, can be installed on the water return pipeline of each branch road of large-scale centralized heat supply, can automatically regulate each regional system flow according to return water temperature, to satisfy each regional flow equilibrium of large-scale heating system, when return water temperature is higher than the self force type temperature regulating valve setting temperature, modulating valve turns down automatically, circling water flow rate diminishes, circling water flow rate became large when return water temperature was lower than the self force type temperature regulating valve setting temperature, make each heating zone supply water temperature identical, to reach energy-conservation purpose.From national winter heating scope, North of Yangtze River is in the winter time heating all, heating area is larger, each district heating time is different, have about the shortest 90 days, also have about 200 days, the energy consumptions such as the annual coal that consumes, rock gas, water, electricity, labour cost and machinery are very large, adopt self force type temperature regulating valve to come large-scale heating system of balance can save 5% energy consumption every year, from management, after self force type temperature regulating valve is installed in each zone of large-scale heating system, need not the people manage, enter normal dimensions behind the 5-8 and repair maintenance.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in the figure, the special-purpose self-supporting temperature-sensing valve of a kind of heating, a hydraulic control valve 22 is established in main valve 21 upper ends, and main valve 21 lower ends connect outlet pipe 20, one type liquid expansion temperature controller 14 is set on the outlet pipe 20, and described type liquid expansion temperature controller 14 is connected by connecting tube 24 pipelines with hydraulic control valve 22.
The type liquid expansion temperature controller 14 that is installed on the outlet pipe 20 of main valve is provided with housing 13, in the housing 13 swelling liquid is housed, and the outlet pipe 20 of described main valve passes housing 13 and is connected with the oil hydraulic cylinder 11 of hydraulic control valve.Thermometer 15 and pressure gauge 16 are housed on the housing 13 of type liquid expansion temperature controller.
During use self-supporting temperature-sensing valve is assembled in the workshop, after finishing, assembling does pressure and temperature adjusting and the test of large and small Flow-rate adjustment, the normal pressure test is 0.8～1.6 MPa, humid test is 30 ℃～60 ℃, flow test decides according to valve aperture and user heating area, be 10,000 square metres such as the user heating area, this valve port directly should be Φ 100mm, and peak rate of flow is set as 30m
3, minimum discharge is 20m
3Self-supporting temperature-sensing valve is installed on the return pipe of each regional system, heating plant is sent 65 ℃～70 ℃ hot water into user's radiator by the heating water supply line when system moves, heat radiation enters heating plant by return pipe heats again, approximately 40 ℃～45 ℃ of return water temperatures.When return water temperature reaches 35 ℃～45 ℃ of setting temperatures, swelling liquid is heated the volume change greatly in the type liquid expansion temperature controller, the swollen liquid of splashing promotes the hydraulic control valve piston by connecting tube, close hydraulic control valve water intake 5 and open simultaneously water outlet 6, large piston 18 pressure drops, small piston 19 moves up under the promotion of elastic member 17 and hydraulic pressure, and simultaneously large piston 18 moves up, and at this moment the heating system circling water flow rate diminishes.When the return pipe temperature drops to setting temperature, type liquid expansion temperature controller 14 interior swelling liquid volumes diminish, hydraulic control valve elastic member 10 promotes hydraulic control valve piston 8 and moves, hydraulic control valve water intake 5 is opened, water outlet 6 is closed, and at this moment water pipe is communicated with main valve, and large piston 18 promotes small piston 19 and moves down under pressure, at this moment circling water flow rate becomes large, and self force type temperature regulating valve is finished the purpose of use.At the self force type temperature regulating valve that install in each zone of large-scale heating system, regulate voluntarily according to return water temperature, regulate temperature and flow equilibrium to reach whole systems.
The utility model main valve adopts the mode of large and small piston, and the source pressure of large piston is the pressure of supply water of getting in the heating system supply channel, and the pressure of small piston is the discharge pressure in the heating system outlet pipe.Hydraulic control valve is by the control of the temperature of the outlet pipe in the type liquid expansion temperature controller, the splashing swollen and shrink the piston operation that promotes hydraulic control valve, the flow of hydraulic control valve opening and closing main valve of swelling liquid.
