Be provided with shock ring on the top of the outer shroud on upper strata and the bottom of lower floor's outer shroud.
Advantageous effect: the utility model provides a kind of outer internal resistance constant current level pressure automatic flow-stop device of leading, comprise housing, being provided with in housing can be along the axially movable spool of housing, spool comprises outer shroud and interior pressure valve dish, outer shroud is arranged on the periphery of interior pressure valve dish, is connected by connecting tendon between interior pressure valve dish and the outer shroud, forms water passage between interior pressure valve dish and the outer shroud, outer shroud and inner walls close contact, the structure of interior pressure valve dish for water intake or the water outlet of housing being shut.
The utility model is installed in the water inlet of resident family's heating installation, when the user discharges water in the caliduct or heating installation when damaging explosion, structure of the present utility model can be shut supply channel automatically, one can prevent that artificial situation about discharging water in the heating installation from occuring, two when the heating installation explosion, also can stop timely supplying water, avoid heating water to waste or flood other property of bubble.
Concrete advantage of the present utility model is as follows:
1: few pressure shades;
2: do not affect flow;
3: the autoshutdown sealing.
4: member is simple, and without frictional loss, the life-span is permanent.
Description of drawings:
Fig. 1 is main structure schematic representation of the present utility model;
Fig. 2 is the main structure schematic representation of the utility model spool part;
Fig. 3 is the stereogram of Fig. 2;
Fig. 4 is the schematic representation of spool when being double layer construction.
Mark 1 among the figure: housing, 2: spool, 3: outer shroud, 4: interior pressure valve dish, 5: connecting tendon, 6: stiffening rib, 7: water passage.
Mode of execution:Below in conjunction with embodiment and experimental technique the utility model is described further:
Lead internal resistance constant current level pressure automatic flow-stop device outside the utility model is a kind of, comprise housing 1, being provided with in housing 1 can be along housing 1 axially movable spool 2, and the arrow shown in the alphabetical A is the axial of housing 1 among the figure; Spool 2 comprises outer shroud 3 and interior pressure valve dish 4, outer shroud 3 is arranged on the periphery of interior pressure valve dish 4, be connected by connecting tendon 5 between interior pressure valve dish 4 and the outer shroud 3, formed water passage 7 between interior pressure valve dish 4 and the outer shroud 3, outer shroud 3 and housing 1 inwall close contact, the structure of interior pressure valve dish 4 for water intake or the water outlet of housing 1 being shut, what letter b and C represented respectively among Fig. 1 is exactly water outlet and water intake.Outer shroud 3 plays spacing effect so that spool 2 can move axially in housing 1 in housing 1.
The gross weight of spool 2 is at 0.25 ~ 1 kilogram, like this will be so that heating system hydraulic pressure when normal, and interior pressure valve dish 4 can be suspended in the housing 1 and can not shut water outlet or water intake.
Effect was best when the connecting tendon 5 between connection outer shroud 3 and the interior pressure valve dish 4 was four, both can guarantee at this moment that join strength also can guarantee suitable water amount, and these four connecting tendons 5 equidistantly arrange on the circumference of outer shroud 3.
Spool 2 is two kinds of structural types, a kind of is Fig. 1 and single layer structure shown in Figure 3, at this moment, the upper and lower surface of interior pressure valve dish 4 is provided with seal rubber pad, top seal rubber pad is to make sealing effect better when shutting filling pipe end, following seal rubber pad is when shutting water intake, makes sealing effect better; And at this moment, also be equipped with shock ring in the upper and lower of outer shroud 3, the effect of shock ring be when interior pressure valve dish 4 is shut rapidly water intake or water outlet, prevent the lower inwall of 3 pairs of housings 1 of outer shroud or on the bump of inwall, thereby protection outer shroud 3 and housing 1 are not damaged.
The another kind of structural type of spool 2 is the structure of Dual-layer, as shown in Figure 4, every one deck has an outer shroud 3 and interior pressure valve dish 4, up and down separately corresponding setting of two outer shrouds 3 and interior pressure valve dish 4, be exactly specifically, the outer shroud 3 of the outer shroud 3 corresponding lower floors on upper strata, the interior pressure valve dish 4 of the interior pressure valve dish 4 corresponding lower floors on upper strata; Be connected by stiffening rib 6 between the outer shroud 3 on upper strata and the outer shroud 3 of lower floor; Top at the interior pressure valve dish 4 on upper strata is provided with seal rubber pad, is provided with seal rubber pad in the bottom of the interior pressure valve dish 4 of lower floor, and the interior pressure valve dish 4 on upper strata is used for shutting water outlet, and the interior pressure valve dish 4 of lower floor is used for shutting water intake.Be provided with shock ring on the top of the outer shroud 3 on upper strata and the bottom of lower floor's outer shroud 3.
The utility model is installed in the feed-water end of resident family's heating installation in use, the water outlet of housing 1 connects the feed-water end of heating installation, and at this moment, spool 2 is in the water inlet, when water inlet, water feeding pressure gradually changes, spool 2 being held up by water feeding pressure gradually, dead-weight balanced with spool 2 behind stable water pressure, the water of heating flows to water outlet through the water passage 7 of spool 2, spool 2 neutral position in housing 1 under the support of water inlet is in the aqueous suspension state, and at this moment, water intake and water outlet all work; And if have the people from heating installation, to discharge water, perhaps heating installation is because when unartificial damage and explosion, because hydraulic pressure instantaneous variation in the heating installation, at this moment, water feeding pressure moment increase, spool 2 is pushed spool 2 to rapidly the water outlet of housing 1 under the impact of water intake hydraulic pressure, 4 moments of interior pressure valve dish are shut water outlet, so just effectively prevented the behavior that artificially heating installation is discharged water, also so that when the heating installation explosion, prevent that heating water runs off in vain.
When pipeline need be repaired or cut off the water, the pressure reduction of water intake and water outlet reduced about 0.01 kg/ cm
2The time, spool 2 just begins to move down action automatically, and water intake is carried out shutoff, has stoped the heating water in the whole building pipeline to be bled off in vain, has avoided waste.
