Abstract

The utility model discloses a heat supply and temperature control regulating valve with shape memory alloy, which is provided with a valve body, wherein both ends of the valve body are connected with a pipe which forms a given angle with the vertical direction, the pipe is communicated with a heating power pipeline, and a U-shaped shape memory alloy is added in the valve body and is connected to a fixing seat below the valve body. The fixing seat is connected to the lower part of the valve body, and both ends of the memory alloy are respectively connected with valve covers of which the size is matched with that of the pipe. The control valve can give the characteristic temperature of the shape memory alloy according to needs, automatically control temperature, save energy, and also nicely regulate indoor temperature. The control valve has two valve covers, so the utility model has the advantages of double opening and closure, fast switch-off, small pressure and long service life. The memory alloy and the plastic valve covers have both corrosion resistance and no rustiness, so the eternal excitability of the valve can be kept, and the valve has simple structure, low cost and easy generalization.

Description

Marmem heat supply temperature regulating and controlling valve

Technical field the utility model relates to a kind of heat supply temperature control valve, is a kind of marmem heat supply temperature regulating and controlling valve specifically.

The temperature of the heat supply that background technique is present often needs to regulate, especially the area of central heat supply, temperature is higher near main line, and the room temperature height not only wastes energy, also unfavorable to health, have in same building, because of keeping supplying layer earlier, upper strata temperature height and lower floor does not also reach temperature required, temperature regulating and controlling valve is very necessary, existing thermostat valve has structure such as spring complicated, and cost is higher, is difficult for extensive use.

The summary of the invention the purpose of this utility model is to provide a kind of marmem heat supply temperature regulating and controlling valve, and it is simple in structure, and control is reliable.

The technical solution of the utility model is as follows:

This regulating and controlling valve is that a valve body is arranged, two ends of valve body connects the pipe in vertical direction with given angle, this pipe is communicated with heat distribution pipeline, add one " U " shape marmem in the valve body, this memory alloy is connected on the fixed base under it, fixed base is connected in valve body lower portion, and the two ends of this memory alloy respectively connect the valve gap that a size cooperates with aforementioned tube.

Above-mentioned marmem is a nitinol.

Above-mentioned valve gap is that engineering plastics are made.

Above-mentioned its angle of pipe in vertical direction with given angle is the 23-30 degree.

Advantage of the present utility model is: 1, this control valve can be set the characteristic temperature of marmem as required, temperature is higher than feature and causes the memory alloy distortion to cold and hot repeatedly positive and negative 1 degree of fixed temperature, demonstrate the ability of remembering original shape under the hot state of cold-peace respectively, drive valve gap and block the two sides pipeline, just can turn-off water inlet or backwater, temperature is lower than feature and just opens A.T.C for fixed temperature, energy saving can also well be regulated room temperature.2, the valve gap of this control valve is two, twoly opens two closing, and turn-offs soon, and pressurized is little, and prolonged working life.3, memory alloy of this device and plastics valve gap are all corrosion-resistant, not corrosion, and the lasting sensitivity of energy maintaining valve is installed slow depressor in the influent stream body pipeline leading portion assembly of this valve before this valve is installed, can make this valve more sensitive reliable; Engineering plastics can be forever indeformable, can forever use.4, simple in structure, cost is low, is easy to promote, and especially is fit to the unified installation in building unit, and high-rise building regulating course and layer heating temperature balance are particularly evident.

Description of drawings Fig. 1 is the utility model cross-sectional view.

The utility model is described in further detail below in conjunction with accompanying drawing for embodiment.

Can see that by Fig. 1 the utility model is higher than the structure of characteristic temperature situation, this regulating and controlling valve is that a valve body 1 is arranged, two ends of valve body connects the pipe 2 in vertical direction with 30 degree angles, this pipe is communicated with heat distribution pipeline, add one " U " shape shape-memory nitinol 3 in the valve body, this memory alloy is through on the fixed base 4 under it, and it is fixing with the binding agent bonding, fixed base is connected in valve body lower portion, it is the lower connecting plate of valve body that the two ends of this memory alloy respectively connect the engineering plastics valve gap 5,6 that a size cooperates with aforementioned tube 2.

When temperature is higher than to fixed temperature, open the shape memory alloy deformation both sides, structure presents austenite phase state, and valve gap is moving thereupon, seals 2 mouthfuls of two side pipes, when temperature is lower than to fixed temperature, marmem restores to the original state, and its structure presents the martensitic phase state, and valve block is moving thereupon, valve gap leaves the above-mentioned mouth of pipe, can intake.
