Abstract
The utility model discloses a thermal static draining valve which is characterized as follows: A washer parentheses 2 and an immovable slide sheet parentheses 3, equipped with an opening parentheses 13 are in turn equipped below a filter mesh parentheses 11 in a body parentheses 1. A mobile slide sheet parentheses 4 is equipped to correspond to the immovable slide sheet parentheses 3 and with an opening parentheses 14 consistent with the opening parentheses 13 and connects a rotary rod parentheses 5 which connects a position limit gland parentheses 8 located at the bottom of the body parentheses 1 and is equipped with a memory alloy torsional spring parentheses 6 one end of which direct connects the body parentheses 1 and the other end of which connects the body parentheses 1 via an offset spring parentheses 7. The utility model may follow the temperature change to drive the slide sheet for rotation by the fit between the above two springs so as to realize the final purpose to control the valve for opening and closing. The utility model is characterized in a little number of parts, simple structure, stable performance and high reliability. Moreover, because the memory alloy torsional spring is solid element and carries a high sensitivity and a rapid reaction, the utility model can stop the leakage and save a large amount of energy.
Description
Technical field:
The utility model relates to a kind of heat supply field drain valve, especially a kind of hot static(al) formula drain valve.
Background technique:
Industrial, in the heating field, adopt usually steam as conduct heat or the work done medium to reach the purpose of heating and production, run well in order to make heating system, energy saving according to different operating conditions, needs to adopt different types of drain valve.Expansion of liquids formula drain valve is comparatively typically a kind of in the art, and this drain valve is a heat responsive element with the topping up bellows, by the opening and closing of expanding with heat and contract with cold control valve of liquid.Although this traditional drain valve is widely used, also there is following several of main problems:
1. in use fatiguability is impaired for bellows, causes managing interior work done dielectric leakage and total failure;
2. bellows element structure and manufacturing process are comparatively complicated, so cost is higher;
3. bellows is on the low side as thermosensitive element sensitivity, is applicable to ± temperature range more than 10 ℃.
Summary of the invention:
The utility model is at the deficiencies in the prior art, and a kind of hot static(al) formula drain valve of simple in structure, reliable performance is provided.
Technical solution of the present utility model is: a kind of hot static(al) formula drain valve, be provided with valve body 1, valve body 1 is provided with inlet 9 and outlet 10,9 places are provided with filter screen 11 at inlet, it is characterized in that: below valve body 1 inner filtration net 11, set gradually packing ring 2 and reach fixedly slide plate 3, fixedly slide plate 3 is provided with port 13, correspondingly with fixing slide plate 3 are provided with moving slide plate 4, moving slide plate 4 is provided with and port 13 corresponding to ports 14, be connected to swingle 5 with moving slide plate 4, swingle 5 joins with the spacing gland 8 of valve body 1 bottom; Be fixed with memory alloy torsion spring 6 on swingle 5, an end of memory alloy torsion spring 6 directly joins with valve body 1, and its other end joins by bias spring 7 and valve body 1.
The line of described memory alloy torsion spring 6 directly is 1.5-3.5mm, and external diameter is 10-20mm, and the number of turns is the 4-7 circle; The line of described bias spring 7 directly is 1-3mm, external diameter 6-10mm, and free length is 7-20mm.
The utility model is along with variation of temperature, and cooperatively interacting by two kinds of springs drives slide plate and rotate, thus the switching of control valve.This device component are few, and are simple in structure, stable performance, reliability height; And because the memory alloy torsion spring is that solid-state components and sensitivity are higher, reaction is fast, does not have leakage problem, can save a large amount of energy.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment:
Below in conjunction with description of drawings embodiment of the present utility model.As shown in Figure 1, 2: a kind of hot static(al) formula drain valve, be provided with valve body 1, valve body 1 is provided with inlet 9 and outlet 10,9 places are provided with filter screen 11 at inlet, filter screen 11 is fixed in the valve body 1 by snap ring 12, it is characterized in that: below valve body 1 inner filtration net 11, set gradually packing ring 2 and reach fixedly slide plate 3, fixedly slide plate 3 is provided with port 13, correspondingly with fixing slide plate 3 are provided with moving slide plate 4, moving slide plate 4 is provided with and port 13 corresponding to ports 14, be connected to swingle 5 with moving slide plate 4, swingle 5 joins with the spacing gland 8 of valve body 1 bottom; Be fixed with memory alloy torsion spring 6 on swingle 5, an end of memory alloy torsion spring 6 directly joins with valve body 1, and its other end joins by bias spring 7 and valve body 1.
Described memory alloy torsion spring 6 best lines directly are 1.5-3.5mm, and external diameter is 10-20mm, and the number of turns is the 4-7 circle.Described bias spring 7 best lines directly are 1-3mm, external diameter 6-10mm, and free length is 7-20mm.
This valve serviceability temperature scope is 30-200 ℃.During drain valve work, steam or water 9 enter in the valve body 1 and directly contact with memory alloy torsion spring 6 from entering the mouth, when being higher than on the setting temperature, water temperature in the valve prescribes a time limit, memory alloy torsion spring 6 is heated, overcome the resistance rotation of bias spring 7, drive moving slide plate 4 rotations, staggered mutually in the port 13 and the position of port 14, valve closing.Reduce under the setting temperature in limited time when water temperature, memory alloy torsion spring 6 shrinks and circles round, and under bias spring 7 bias force effects, moving slide plate 4 resets, and makes port 13 consistent with the position of port 14, with valve open.Drain valve is discharged to low-temperature circuit with the cryogenic media in the valve from valve opening and heats like this, thereby guarantees that loop temperature is constant.Bias spring 7 places minimum working torsional angle with memory alloy torsion spring 6 during installation, makes the memory alloy torsion spring keep certain pretightening force.
Be 16 atmospheric industrial heating equipment for vapor pressure for example, needing operating temperature is 100 ℃ drain valve, then should select for use line directly to be 2mm, and spring inside diameter is 7mm, and the number of turns is the memory alloy torsion springs of 4 circles; Line directly is 1.2mm, external diameter 6mm, and free length is the bias spring of 8mm.When water temperature reaches the setting temperature upper limit (100 ℃) memory spring be heated the rotation angle offset spring be elongated 15mm, this moment the valve Close All, when water temperature dropped to setting temperature lower limit (80 ℃), memory spring shrank, and opens at bias spring effect lower valve.When water temperature raise again, valve was closed again, and so repeatedly, valve normally moves, and steam-heating system is worked in the best condition.
