Abstract
The invention relates to a transmitting type impeller of a heat meter flow gauge, consisting of a transmitting plate (1), vanes (2), a hub (3), a shaft sleeve (4) and reinforcing ribs (5), wherein the surface of the transmitting type impeller is metallized; the transmitting plate can serve as a flow sensor and a transmitter of flow signals; the transmitting plate, the vanes, the hub and the reinforcing ribs are integrally poured and molded by engineering plastics and ceramic materials for a shaft sleeve; and the transmitting plate is in a strip shape, is arranged between two vanes and is fixedly connected with lateral sides of the vanes, and the transmitting plate plane is vertical to the axis of the shaft sleeve. The transmitting type impeller serving as a core component of the heat meter flow gauge has the advantages of high impeller uniformity, good dynamic balance and simple processing technique.
Description
One, technical field
The present invention relates to the hot metering field of building and heating, is a kind of writing style impeller of heat meter flow.
Two, background technology
The metering of building and heating heat is an important energy saving environmental practice, just can realize the metering of heating heat by calorimeter is installed in the user heating pipeline.Be used for the mechanical type calorimeter of building and heating heat metering, propeller flowmeter is installed in it, and the impeller of propeller flowmeter be its critical component.What the calorimeter propeller flowmeter of prior art adopted is the blade wheel structure of multithread bundle or single channel, though this propeller flowmeter has quantification stability and accuracy advantage of higher, but the propeller flowmeter of this structure is easily stopped up by the foreign material of heating hot water, thereby causes calorimeter failure rate height, error in dipping is big, the life-span is short.Prior art also has a kind of novel calorimeter, it is at the susceptible to plugging technological deficiency of mechanical type calorimeter, a kind of brand-new design theory of calorimeter has been proposed, adopt three big SST technology of symmetrical structure, straight-through pipeline and transverse axis impeller system, be subjected to foreign material blocking problem in the water thereby make the SST calorimeter solve flowmeter effectively.Application number is 200620136106.5 to disclose " a kind of flowmeter impeller ", and this impeller is the flowmeter impeller of SST calorimeter.The flowmeter impeller of SST calorimeter has solved the coupled problem that flow sensing and flow are posted a letter, and promptly embeds the silicon steel sheet of posting a letter on the impeller of flowmeter, makes impeller can respond to flow rate of fluid and the wheel speed signal can be sent again.Yet this impeller exists some shortcomings, shows as: the silicon steel sheet of posting a letter of embedding makes that the uniformity coefficient of impeller descends, the transient equilibrium variation; In addition, in order to embed the silicon steel sheet of posting a letter, add in the impeller injection moulding and need carry out quadric injection mould man-hour, complex process, difficulty of processing increase, chilling temperature is high and cause the impeller distortion after the injection moulding.The present invention is directed to the deficiency of this impeller of prior art, propose a kind of writing style impeller of heat meter flow.
Three, summary of the invention
The present invention is made up of letter board, blade, wheel hub, axle sleeve and reinforcement.Plating metal on surface is taked on the surface of writing style impeller; Letter board not only as the inductor of flow, but also as the sender unit of flow signal.Why letter board can be as the sender unit of flow signal, its principle just has been to utilize its plating metal on surface, with the axially perpendicular area of axle sleeve the otherness of three-dimensional area distributions on big and this direction, provide the no magnetic induction LC oscillating circuit to measure the signal generating source of flow signal; Letter board, blade, wheel hub, reinforcement adopt the integral molded plastic moulding with engineering plastics, axle sleeve stupalith; Letter board is a strip plate, and the plane of its plate and axle sleeve axially perpendicular fixedlyed connected between two blades and with the side of blade; Letter board is that the center is symmetrical distribution with the axle sleeve; Reinforcement is the strip plate, and fixedlying connected with the blade middle part respectively in the two ends of its plate, plays the intensity that increases blade.
The present invention is made up of letter board, blade, wheel hub, axle sleeve and reinforcement, and plating metal on surface is taked on its surface; Letter board, blade, wheel hub, reinforcement adopt the integral molded plastic moulding with engineering plastics, axle sleeve stupalith; Letter board not only as the inductor of flow, but also as the sender unit of flow signal.The present invention has impeller uniformity coefficient height, good, the simple advantage of processing technology of dynamic balance as the core component of heat meter flow.
