Abstract
The utility model discloses a shape memory alloy heat supply temperature control adjusting gate valve which comprises a 'cross' shaped valve body, namely that a vacuum valve is inserted into a horizontal pipe, the middle part of the vacuum valve is communicated with the horizontal pipe, and both ends of the horizontal pipe are communicated with a heat supply pipe; heat resistant gate plates are arranged on both ends of the vacuum valve; single-pass shape memory allow springs are relatively arranged on top of the gate plates; pipe plugs are arranged on the outer ends of the springs; bulges are arranged on the middle parts of the gate plates; return springs are arranged inside interior valve bodies of the bulges. The utility model can set single-pass shape memory alloy characteristic temperature as required; shape memory alloy is corrosion and rust resistant, thereby the persistent susceptiveness of the valve can be maintained; due to the structural design of the valve, shearing force is overcome, the impact of hydraulic pressure on a switch of the valve is low, and no gradual pressure and assistant power are needed, thereby the cost is lowered. The utility model also has the advantages of being capable of free assembling and disassembling, convenient maintenance and replacement, and long service life. Moreover, because the utility model uses the single-pass shape memory alloy instead of double-pass shape memory alloy, the cost is greatly lowered, and the valve is led to easy promotion.
Description
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 temperature of first heat supply in Stall is higher, the temperature height not only wastes energy, and health is also had adverse effect, and the pipeline temperature of first heat supply in the building that has surpasses preference temperature, the floor of back heat supply does not reach temperature required, and temperature controlling device is very necessary.Existing marmem heat supply temperature regulating and controlling valve, as the patent No. is 200520145651.6, need with marmem be round trip, volume is bigger, and is also heavier, and the market price of existing marmem is higher, particularly the two-way shape memory alloy is more expensive, be one-way shape memory alloy price 4-5 doubly, with the valve body cost height of two-way shape memory alloy, be 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 gate valve, and its cost is low, and control is reliable.
The technical solution of the utility model is as follows:
This valve is that " ten " font valve body is arranged, and promptly vacuum valve inserts in the transverse tube, is communicated with transverse tube in the middle of it, and the transverse tube two ends are communicated with heat supplying pipeline; The two ends of vacuum valve have heat-resisting brake lining respectively, on the top of brake lining the one-way shape memory alloy spring are housed respectively, this spring outer end dress plug; There is projection at the brake lining middle part, reinstalls a spring in the inboard valve body of above-mentioned projection.
Above-mentioned one-way shape memory alloy spring is the spring that titanium nickel one-way shape memory alloy is made.
Above-mentioned heat-resisting brake lining is semicircular.
Above-mentioned heat-resisting brake lining is to be made by the nylon-66 that glass fibre strengthens.
The return spring of being adorned in the above-mentioned protruding inner valve body is coated with the corrosion-resistant metal layer.
Advantage of the present utility model is: 1, this valve can be set one-way shape memory alloy characteristic temperature as required.2, the lasting sensitivity of the corrosion-resistant not corrosion energy of the marmem of this device maintaining valve.3, owing to the structural design of this valve, what overcome is shearing force, and hydraulic pressure is little to the open and close influence of valve, need not delay pressure and power-assisted and reduce cost.4, the two ends of the vacuum valve of this device are plugs, and dismounting at any time, to keep in repair, change part convenient, long service life.This valve greatly reduces with the marmem of one-way shape memory cost of alloy than round trip, makes this valve be easy to promote, and particularly regulates the heat supply temperature between the floor in Stall.
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.
Can see structure of the present utility model by Fig. 1, this valve is that " ten " font valve body is arranged, and promptly vacuum valve 4 inserts in the transverse tubes 5, and 6 are communicated with transverse tube in the middle of it, and the transverse tube two ends are communicated with heat supplying pipeline; The two ends of vacuum valve have heat-resisting brake lining 2 respectively, and it is made by nylon-66, and titanium nickel one-way shape memory alloy spring 1 is housed respectively on the top of brake lining, this spring outer end dress plug; There is projection 3 at brake lining middle part, in the inboard valve body of above-mentioned projection brake lining about respectively dress be coated with the return spring 7 of corrosion-resistant metal layer, the protruding outside of brake lining is that cylindrical inboard is semicircular.
Cause the one-way shape memory alloy spring to fixed temperature and expand when temperature is higher than, upspring, when its elastic pressure during greater than the elastic force of return spring, two brake linings 2 that promote vacuum valve move and close up to the centre, turn-off water inlet; When temperature is lower than to fixed temperature, one-way shape memory alloy spring unloading acting at the effect lower brake pad return of return spring, is opened water intake.
