Description

Water automatic stop arrangement on a kind of solar energy

Technical field

The utility model relates to liquid level automatic control valve, water automatic stop arrangement on specifically a kind of solar energy.

Background technology

The solar water heater that uses generally all has water inlet pipe, overflow pipe two tubes at present, needs the Artificial Control valve in last water process.Treat full back waterborne if the untimely water supply valve door of closing can cause the waste of running water.In addition, cut off the water, close penstock and also can cause the aqueous reflux in the water tank to go into pipe network system, both polluted the pipe network water source, can cause again that water heater high temperature is empty to be shone, after pouring into low-temperature cold water, can cause water heater to damage if be not related to if just meet in the last water process.The ZL99227330.7 patent disclosure the automatic water control valve of a kind of solar water heater water tank, its structure is that spool is arranged in the valve body, the lower end of valve rod and spool and rubber cushion connect, the upper end and the float of valve rod join, spool is an oviduct, have two parallel arms and water tank to join on the valve body, cover plate is established on valve body top, and the circle centre position of cover plate adds guide plate.This automatic water control valve is arranged on the outside, concordant with tank top of water tank, can control automatically the state of filling up water case.But its structure relative complex is installed inconvenience to some extent, uses to also have certain limit that lacks.

The utility model content

The purpose of this utility model just provides water automatic stop arrangement on a kind of solar energy simple in structure, easy for installation, to overcome the deficiency of existing apparatus, satisfies the use needs of solar water heater.

The utility model is achieved in that to be welded with on interior bucket inwall carries frame, carries and is connected to lifting chain bar on the frame, and the upper end of chain bar is articulated in the end of rotating the arm of force, and the other end of the rotation arm of force and the valve rod end that the water supply valve door stretches out are affixed; Bucket was suitable for reading in overflow pipe stretched into, and had able to turn on or off delivery port in interior bucket bottom.

Adopt this structure, pull the former spanner of water supply valve door, open valve, give the solar water heater water filling.At this moment, be fixed in the rotation arm of force on the valve rod and horizontal direction and the vertical direction of hanging down all has certain included angle.After water was full, the backwater that flows out from the overflow pipe of solar water heater entered interior bucket.The deadweight of ponding produces downward active force by the end that the chain pole pair rotates the arm of force in the bucket.Owing to the long rotation arm of force can produce leverage, therefore, less ponding can produce the bigger rotation arm of force in the bucket, and when water accumulating volume in the bucket was enough to drive the rotation of water supply valve family of power and influence bar, staving descended, and rotates the arm of force simultaneously and rotates, and closure valve stops to go up water.Can by open interior bucket bottom delivery port ponding bled off after, pull spanner when using next time again, opens the water supply valve door, goes up water once more.

The simple frame for movement of the utility model utilization realizes the last water automatic stop of solar energy, has characteristics simple in structure, durable, with low cost; Because the utility model can directly be installed at the indoor of solar energy user, and, only need the rotation arm of force is installed on the valve rod, no matter need not pipeline is changed, therefore, be the user for new installation solar energy, still existing solar energy user's transformation, installation of the present utility model is all very convenient, therefore, very is suitable for large tracts of land and promotes.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

Below in conjunction with Fig. 1 the utility model is described in detail

The water automatic stop arrangement is to be welded with to carry frame 9 on interior bucket 2 inwalls on this solar energy, carries and is connected to lifting chain bar 5 on the frame, and the upper end of chain bar is articulated in the end of rotating the arm of force 6, and the other end of the rotation arm of force and the valve rod end that the water supply valve door 7 on the upper hose 8 stretches out are affixed.Bucket 2 was suitable for reading in the overflow pipe 4 of solar water heater stretched into, and had able to turn on or off delivery port in interior bucket 2 bottoms.This delivery port can be the outlet pipe that valve is housed, and last this delivery port of water front opening bleeds off the ponding in the interior bucket.During last water, delivery port is closed, to store the water that overflow pipe overflows.

For the purpose that the ponding in the bucket in reaching can be emitted automatically, the delivery port of interior bucket 2 preferably sets out water hole 11 at the bottom of bucket, and the screw rod top that wears in the hole is provided with the cover plate 10 of belt glue pad, at the bottom of stretch out barrel the lower end, and is fixed with locating part 14 by nut 12.Locating part 14 can be the thin slice of belt glue pad not, also can be the hack lever structure.Adopt this structure, under gravity effects such as cover plate 10 self and screw rod, cover plate 10 sealing delivery ports.And after the ponding in the interior bucket reached constant weight, behind the valve-off, the supported underneath thing was touched in the staving of decline bottom, with the screw rod jack-up that makes progress, opened apopore 11, emitted barrel an interior ponding, prepared against next use.By the fixing locating part 14 of nut 12, be in order to prevent that cover plate 10 and screw rod from deviating from apopore 11 under a top of supporter.

In order to make the utility model more attractive in appearance, easier for installation, preferably interior bucket 2 is set in the outer bucket 1, overflow pipe 4 is fixed on the lid 3 of outer bucket 1, bucket 1 in the mouth of pipe is aimed at.The bottom of bucket 1 has scupper 13 outside.This structure, when interior bucket 2 descended under the effect of ponding gravity, the bucket end of outer bucket 1, touched in the screw rod lower end, opens apopore 11, and ponding flows in the outer bucket 1, flows out from scupper 13 again.

In the utility model use, the rotation arm of force 6 of control water supply valve door closure is when heeling condition goes to level, chain bar 5 also descends thereupon, for adapting to this decline process, chain bar 5 is preferably joined by chain, bar and constitutes, so that when descending, chain bar 5 can bend to some extent, reaches ascending, descending purpose freely.

The utility model should note making bottom and the lower support thing surface of the interior bucket 2 when being in water state that the unsettled of certain distance arranged when mounted, drops to can be with the height of valve closing the time to guarantee staving, and barrel end of interior bucket 2 just can touch at the end, is supported.
