Abstract

The utility model relates to a water heating self-control valve composed of a circular tube 1 and an expansion and shrinking capillary core 2 arranged in the tube; the utility model is expanded to close when contacted with water; the utility model discharges air when contacted with air. The utility model can replace an air valve of the existing heater; installation ways and positions are not changed. The utility model has the advantages of simple structure, constant volumes, low cost, etc., which realizes automatic air discharge as well as prevents hot water from being stolen to use from the air valve.

Description

The hot-water heating internally piloted valve

The utility model is a kind of mechanical device, promptly a kind of hot-water heating internally piloted valve.

Regular meeting produces gas in the hot-water heating equipment operation, and these gases such as untimely emitting then can cause current to be obstructed, thus the influence heating.Therefore, in heating equipment, all outlet valve to be installed.Present outlet valve has automatic control pressure vent and manual exhaust valve.The automatic vent valve arrangement is complicated, and cost is higher, can not close immediately when exhaust finishes, and also can spray some water, thereby is not suitable for installing in the room.What install in the room is a manual outlet valve, also cries and runs wind, generally is positioned on the angle of central heating plate.During exhaust, turn on, after gas has been put, close immediately before the water spray and get final product by the people.This outlet valve volume is little, and cost is low, is used widely., this valve also exists many shortcomings: the one, can not automatic vent, and on a circulation loop, there is user's family unmanned, will cause blocking-up, influence heat supply.In addition, existing race wind also can be used to usurp hot water, causes irrational waste.

The purpose of this utility model is that a kind of chance gas of development is promptly opened, and meets water and promptly closes, and can not usurp hot water, and be difficult for sticking with paste the extension incrustation scale, and volume is little, and cost is low, can replace a kind of internally piloted valve of existing manual exhaust valve.

Technological scheme: this outlet valve also is a pipe, and an end has the screw thread that is connected with central heating plate, and different is to be plugged with a swollen capillary core that contracts in the pipe.

The said swollen capillary core that contracts can be a bamboo reel.

The outlet valve that adopts such scheme to make, be fixed on the warmer, aerogenesis in the warmer can be discharged by capillary tube, meet water then around the capillary tube material expand and close, hang incrustation scale but also be difficult for sticking with paste, this existing race wind structure is also simple, cost is also low, and appearance similar, still is installed on the original position, thereby popularize easily, market prospects are very considerable.

Introduce two kinds of embodiments below in conjunction with accompanying drawing.

Fig. 1 is first kind of embodiment's a plan view, and Fig. 2 is its left view.

Fig. 3 is second kind of embodiment's a plan view, and Fig. 4 is its left view.

Fig. 5 is the scheme of installation of this product.

Pipe 1, the swollen capillary core 2 that contracts, anti-logical sheet 3, race wind 4, plug 5 are arranged among the figure.

As shown in Figure 1 and Figure 2, this internally piloted valve is as long as have pipe 1 and the swollen capillary core 2 that contracts to get final product work.The swollen capillary core that contracts can be used bamboo making, also can make of other materials.When meeting water, promptly inflatable, water goes out not go.Run into gas and then can in pore, go out, thereby play the effect of venting.

Fig. 3, Fig. 4 introduction be that this internally piloted valve is positioned on the situation on the plug 5, plug is mounted in the part on the central heating plate, will notice that wherein internally piloted valve packs in plug the inside, is difficult for like this being removed.In the swollen capillary core front of contracting, be provided with anti-logical sheet, can prevent that the people from inwardly pricking the hole, makes capillary core ineffective.Anti-logical sheet can also replace with the through hole of bending.The outside is equipped with equally and is run wind 4, can prevent infiltration.Adopt this structure, get final product automatic vent, can prevent that again the people is for usurping hot water.

As shown in Figure 5, this valve is installed on the last angle of central heating plate, promptly existing position of running the wind installation then gets final product proper functioning.

Claims

1, a kind of hot-water heating internally piloted valve also is a pipe, and an end has the screw thread that is connected with warmer, it is characterized in that: be plugged with a swollen capillary core that contracts (2) in the said pipe (1).

2, hot-water heating internally piloted valve according to claim 1 is characterized in that: the said swollen capillary core that contracts can be a bamboo reel.
