Abstract

The utility model discloses a shape memory alloy heating temperature controlling-adjusting wedge valve, which comprises a transverse tubular valve body communicated with a heating pipeline, a longitudinal tube vertically connected with a transverse tube, a wedge nail through the longitudinal tube, a shape memory alloy spring at the upper of the nail, a deflected spring at the lower of the nail, a plug or a cover at the top of the longitudinal tube, a plurality of blades uniformly distributed in the transverse tube and an axle rod at the middle of the blade wheel. The valve can be made from the shape memory alloy with short heating drive stroke and low cost to reduce the price. The shape memory alloy is resistant to corrosion to keep the sensitivity of the valve. The water and gas pressures have little effect on the drive of the valve and the valve can be made into different apertures. The valve can be detached and maintained freely and can exchange elements easily, with long service life. The valve is suitable for unified installment in one building unit.

Description

Marmem heat supply temperature regulating and controlling wedge valve

Technical field

The utility model relates to a kind of thermostat valve, is a kind of marmem heat supply temperature control valve specifically.

Background technique

Present heat supply temperature needs to regulate, especially the area of central heat supply, higher from the general heat supply temperature of the near building of main line, the floor heatsink temperature height of first heat supply in Stall, its room temperature is higher, and the temperature height not only wastes energy, health also there is adverse effect, the pipeline temperature of first heat supply in the building that has surpasses preference temperature, and the floor of back heat supply does not reach temperature required, and temperature controlling device is very necessary.Energy saving, harmonious relation between supply and demand, simultaneously the user keeps suitable steady temperature heating, be benefit the nation, favorable to the people major issue.Existing marmem heat supply temperature regulating and controlling valve, as the patent No. be 200520145651.6 and application number be 200720012130.2, because of being subjected to the influence of hydraulic pressure air pressure, the flexibility that influences the valve driving in various degree, bigbore valve is influenced heavier, and the cost of production height is difficult for promoting.

Summary of the invention

The purpose of this utility model is to provide a kind of marmem heat supply temperature regulating and controlling wedge valve, and its cost is low, and multiple bore control is highly sensitive.

The technical solution of the utility model is as follows:

This valve is that the transversal tubular valve body is arranged, and it is communicated with heat supplying pipeline; Vertically pipe is connected with transverse pipe is vertical, vertically runs through the wedge nail in the pipe, and shape memory alloy spring is equipped with on the top of this nail, and a bias spring is adorned in the bottom of above-mentioned wedge nail, vertically the top of pipe dress plug or lid; The blade that the dress angle all claims in transverse pipe, dress axostylus axostyle in the middle of the blade wheel.

Above-mentioned shape memory alloy spring is the spring that Ti-Ni marmem is made.

Above-mentioned wedge nail is to make of good heat resistance, water-tolerant, thermoplastic engineering plastic molding and forming that crocking resistance is high.

Above-mentioned blade is four, is half garden shape, and it is to make of good heat resistance, water-tolerant, crocking resistance high thermoplastic engineering plastic or polyurethane elastomer molding and forming.

Advantage of the present utility model is: 1, this valve can be set the marmem characteristic temperature as required, temperature is higher or lower than feature and causes the cold and hot driving of shape memory alloy spring for fixed temperature 1-2 degree, be fit to applying shape memory alloy heat and drive the short material of stroke, this material price is lower, and this valve is that 200720012130.2 valve reduces cost 1/3rd than application number.2, the lasting sensitivity of the corrosion-resistant not corrosion energy of the marmem of this device maintaining valve.3, because the structural design of this valve, water, atmospheric pressure are minimum to the driving influence of this valve, and this valve can be made multiple bore.4, the building unit is high-rise installs this device reduction reforming cost with low layer on the water return pipeline of double vertical stringing, transform simple to operation.5, the two ends of this device are plug or lid, and blade wheel is through on the fixed axostyle, and the two ends of axostylus axostyle are with fixedly shutoff of closure nut, dismounting at any time, keep in repair, change part and make things convenient for long service life.This valve is fit to the unified installation in building unit, and the pipeline of single vertical stringing is transformed still and can be installed, and heat supply upgoing type and descending type can be installed and used, layer and layer, and chamber and chamber heating temperature balance are particularly evident.

Description of drawings

Fig. 1 is the utility model overall structure generalized section.

Embodiment

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

This valve is that transversal tubular valve body 8 is arranged, and it is communicated with heat supplying pipeline; Manage 2 longitudinally and be connected with transverse pipe is vertical, vertically run through thermoplastic engineering plastic wedge nail 4 in the pipe, one way Ti-Ni marmem spring 3 is equipped with in this portion of nailing on, a bias spring 5 is adorned in its underpart, there is projection 1 at the middle part, and in order to fix two springs, vertically plug or lid are adorned in the top of pipe; Four blades 6 that the dress angle all claims in transverse pipe, it is half garden shape, dress axostylus axostyle 7 in the middle of the blade wheel, the two ends of axostylus axostyle are with fixedly shutoff of closure nut; Above-mentioned blade is to make of the high thermoplastic engineering plastic of good heat resistance, water-tolerant, crocking resistance.

When being higher than to fixed temperature, temperature causes the shape memory alloy spring expansion, upspring, bias spring is applied biasing force and shrinks, promoting the wedge nail drives in transverse pipe, be pushed in the transverse pipe, follow closely the blade that blocks rotation status in this pipe, stop operating by wedge, the inner gateway of transverse pipe is blocked, turn-offed water inlet, backwater.When being lower than to fixed temperature, temperature causes shape memory alloy spring unloading work done, after the suffered biasing force unloading of bias spring spring function, upspring, restore to the original state, promote the wedge nail and outside transverse pipe, drive, blade in the transverse pipe recovers rotation under the pressure of water, gas, open water inlet, backwater.
