Description

Inhalation valve

The utility model relates to a kind of on the blowdown pipe at gas pressure water tank top, is used for air-breathing and inhalation valve tonifying Qi.

The inventor's patent application (96209216.9) once proposed, and adopted and sprayed air supply tank is implemented automatic tonifying Qi to gas pressure water tank scheme.It has effectively overcome on general pneumatic installation water supply, and height establishes air supply tank, stop water pump implements the device miniaturization that can't realize on the old scheme of tonifying Qi and problem such as energy-conservation.

On this basis, spray the air supply tank upper vertical and erect lucite tube, then at its top by a kind of can be air-breathing again can tonifying Qi valve mechanism, when being connected with horizontal blowdown pipe 90 degree on gas pressure water tank top, this lucite tube will play sucking pipe, blowdown pipe, water level indicator tube, these three kinds of effects.Not only can save the water level indicating device of gas pressure water tank, whole automatic tonifying Qi and running that also can open-and-shut observation gas pressure water tank.

Usually can adopt the reverse parallel connection scheme of two general check valve.Promptly connect lucite tube and blowdown pipe, allow it play the tonifying Qi effect with an angie type lift check valve 90 degree; The parallel air-breathing safety check of using of inversion another on the next door of this valve; Then, two valve bottom conduit parallel connections.This scheme not only outward appearance is not beautiful, also because parallel pipeline is bigger in two interior valve setting height(from bottom)s, has increased the total height of equipment.In addition, general general check valve on the hot-water heating pipeline, relatively poor to the sealing of gas, often influence tonifying Qi efficient.

In view of above situation, the purpose of this utility model provides a kind of small-sized inhalation valve, come 90 degree to connect the horizontal blowdown pipe at gas pressure water tank top and the lucite tube that injection air supply tank upper vertical is erect with it, promptly save the water level indicating device of gas pressure water tank, observe whole automatic tonifying Qi process again at a glance, also improve tonifying Qi efficient.

The purpose of this utility model is achieved in that at the little valve inner of rectangle and sets up A, B two chambeies separately, bottom, two chambeies interconnects, top, A chamber is provided with the conical reaction trap that backs down with very little pressure reduction downwards, and the disc reaction trap upwards back down is set on top, B chamber, bottom and upper lateral part at this valve are provided with two connecting-tube nozzles respectively, and 90 degree connect lucite tube and blowdown pipe.As A, when bottom, B chamber is in negative pressure, ambient air backs down conical reaction trap, sucks through lucite tube and sprays blowdown pipe; Otherwise, when A, bottom, B two chamber are in malleation and rise near the gas pressure water tank top pressure, back down the disc reaction trap, be pressed into the gas pressure water tank tonifying Qi through blowdown pipe.

This combined type inhalation valve of the present utility model when the external diameter of organic glass tube is φ 20mm, has narrowed down to body size within 90 * 50 * 70mm, and its setting height(from bottom) only is half of general check valve reverse parallel connection scheme, reduces the about 150mm of device height.And the high sealing structure that interior two valve of valve body are taked makes tonifying Qi efficient, and promptly the ratio of the design aspirated volume of the air compensation of the gas pressure water tank of this valve of process and injection air supply tank has reached more than 95%.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is the sectional drawing according to the inhalation valve that the utility model proposes.

Fig. 2 is the air compensating system figure that adopts the gas pressure water tank of the utility model inhalation valve.

Below in conjunction with Fig. 1, describe structure in detail according to the inhalation valve that the utility model proposes.It comprises: valve body (1), the Aspirating valves part of forming by guide sleeve (2), spring (3), air suction valve (4) and air-breathing valve gap (6) etc., aeration valve part and welding tube head (13) and the cap nut (16) etc. formed by exhaust valve cap (10), tonifying Qi valve (11) and edge of a knife shape seal valve seat (14) etc.

Air aspiration cavity (A) and tonifying Qi chamber (B) are set up separately in the inside of rectangle valve body (1), and bottom, two chambeies interconnects; Then the right side in B chamber and following each protrude two connecting-tube nozzles (b) and (c) are set; Connecting-tube nozzle (b) will be through welding tube head (13) on the right, blowdown pipe (2.7) the welding (see figure 2) at along continuous straight runs and gas pressure water tank top; And in following connecting-tube nozzle (c), will insert the top of lucite tube (2.6), tighten up sealing with cap nut (16).

In the A chamber of valve body (1), be inserted in guide pipe (2), spring (3) and air suction valve (4) earlier afterwards, air-breathing valve gap (6) is tightened in this upper internal threaded hole, chamber, the inboard of the horizontal inlet hole (a) on top, heart hole therein again, put into filter screen (7), cover guard shield (8), constitute the air-breathing part of inhalation valve; Wherein, air suction valve (4) is the 60 degree circular cone valve that a kind of epimere is with O shape rubber seal (5), and the guide rod of its hypomere portion inserts in the center hole of guide sleeve (2), is in upwards closed condition by the weak elastic force of spring (3).

And in the B chamber of valve body (1), put into edge of a knife shape seal valve seat (14) and tonifying Qi valve (11) earlier, and tighten exhaust valve cap (10) at the interior threaded hole on this top, chamber then, constitute the tonifying Qi part of inhalation valve; Wherein, tonifying Qi valve (11) is a kind of disc valve, its bottom is provided with the rubber bushing (12) that compresses with bolt (15), the guide rod both sides on this valve top have vent slot, and be inserted in the center hole of exhaust valve cap (10), close edge of a knife shape seal valve seat (14) downwards by the deadweight of valve at ordinary times; Tighten plug screw (9) at the interior threaded hole on valve gap (10) center hole top at last, only putting, gas leaks from top.

Below in conjunction with Fig. 2, further introduce the working principle of inhalation valve.

In the drawings, the 2.1-inhalation valve, the 2.2-gas pressure water tank, the 2.3-feed water pump, 2.4-sprays blowdown pipe,

2.5-solenoid valve, 2.6-lucite tube 2.7-blowdown pipe.

Between the on-stream period of feed water pump (2.3), make when spraying the suction of blowdown pipe (2.4) water spray when opening solenoid valve (2.5), in lucite tube (2.6), produce vacuum, thereby ambient air is through the inlet hole (a) on the inhalation valve, back down air suction valve (4), enter A, bottom, B two chamber, spray in the air supply tank (2.4) from the lucite tube suction of connecting-tube nozzle (c).

Make injection pressure water in the injection blowdown pipe (2.4) when closing solenoid valve (2.5), compress air in it and during near the top air pressure of gas pressure water tank (2.2), back down the tonifying Qi valve (11) in the inhalation valve B chamber, from horizontal connecting-tube nozzle (b), through blowdown pipe (2.7), flow into the top of gas pressure water tank (2.2), till water level balances each other in water level in lucite tube and the gas pressure water tank.

Many weeks, the elasticity of water is very little, and is compressible hardly, and the elasticity of gas and compressibility are very big.Therefore, when opening solenoid valve (2.5), spray the air-breathing initial stage of air supply tank (2.4) water spray, the A of inhalation valve, bottom, B chamber pressure drop to from gas pressure water tank pressure suddenly and are lower than zero gauge pressure.Thereby cause the unexpected unlatching of circular cone valve (4) and the unexpected pass closed procedure of disk valve (11).At this moment, because disk valve (11) is pressed on suddenly on the edge of a knife shape valve seat (14) with very big upper and lower pressure reduction, prevented the refluence of gas in the gas pressure water tank at once, making the interior inhaled air of the actual volume of spraying air supply tank (2.4) nearly all is ambient air.But the process of closing water filling pressurized gas in solenoid valve (2.5), the injection air supply tank is more slowly.If the air suction valve of inhalation valve also adopts the same inversion valve of disc valve (11), though then can further reduce body size, but because valve below pressure rises slower, can not the be unexpected rubber bushing of disk valve (12) be compressed on the edge of a knife shape valve seat, the air that a part is being compressed discharges from (a) hole, reduces air compensation.So air suction valve of the present utility model has adopted the conical valve of 60 degree that has O shape rubber seal (5).Because its good to centrality upwards promotes valve by spring (3), is in already and closes sealing state, prevented effectively in the slow compression process to external leakage.Almost all be pressed into the gas pressure water tank tonifying Qi thereby spray air supply tank institute amount of air drawn, tonifying Qi efficient is brought up to more than 95%.

In addition, only depend on the disk valve (11) of deadweight lifting, when its below pressure rises to 80% when above, to valve opening direction air-flow in the same way of top pressure, lose sealing (salable fully) fully, equate just to stop to flow up to upper and lower pressure to adverse current.Therefore, the highest water level in the lucite tube (2.6) equals the water level of gas pressure water tank (2.2), has played the effect of water level indicator tube.
