Description

Level-adjustable piston-type combined automatic valve

The utility model is a kind of novel piston formula combination self-acting valve.Can regulate the structure of liquid level height and simplification water tank especially easily.Be suitable for the level control of various automatic loading water system water tank, water tower etc.

What existing water tank or water tower adopted is that Metal Ball even compresses the ball valve that valve carries out level control by a cross bar.What sell on the market is exactly the ball valve of this pattern.The control liquid level is just to design fixed liquid level height when building water tank, can not regulate arbitrarily, builds an intake pipe above the water tank, and ball valve is installed on the intake pipe, builds an outlet pipe below, and installation one goes out water one-way valve, thereby the liquid level of finishing water tank is controlled automatically.This water tank is made complicated, high material consumption.Because this ball valve poor stability often can not reach the effect of sealed valve.Cause a large amount of water to diffuse out from water tank.According to investigations, the most now water tank in the whole nation all has casual water phenomenon, causes the water resource waste of thousands of tons.

Task of the present utility model provides a kind of brand-new piston type combination self-acting valve, and it can make the manufacturing of water tank simplify, and level control is flexible, and stability is strong, eliminates the purpose that water tank overflows water.

Task of the present utility model is finished as follows: adorn the Metallic cylinder of opening several paddle holes on the wall in the valve body of a garden type, a ring-like mouth less than cylinder sleeve body diameter is inwardly formed at the top of cylinder sleeve, edge one circle rubber ring in ring-like mouthful.The cylinder sleeve outer has the silk mouth to be connected with valve body.Be convenient to dress like this, tear open., there is connecting rod in top generation, and the piston of have three road collar extensions, loading onto elastic piston ring places in the cylinder sleeve.Connecting a metal bracelet on the connecting rod of piston is connected with the ball float on top.Adorning small spring formula water inlet one-way valve, valve body lower portion on the valve body has silk mouthful to link to each other with the shared water pipe of turnover.Need when water tank water intake, piston body drops to inferior part of the cylinder block at built-in spring and action of gravity, and the water inlet on the cylinder wall is communicated with water tank, and baby check valve is closed.Water enters valve body from passing in and out shared water pipe, through paddle hole, the ring-like mouth in cylinder sleeve top enters water tank, rises to when giving fixed position when the water surface, ball float drives piston and rises to cylinder sleeve top, paddle hole on the cylinder sleeve is cut off, because the hydraulic pressure that has the airtight acting cylinder of three road elastic piston rings to put interior collar extension rubber ring and piston ramp contacting point greatly reduces, only a small amount of buoyancy that needs ball float to drive just can be airtight fully, at this moment, water tank reaches to give decides liquid level, and water inlet is turn-offed.Hydraulic pressure reduces in the shared water pipe of turnover, in water tank under the hydraulic action, spring one-way valve opens on the valve wall, water in the water tank enters water pipe through one-way valve, liquid level in the water tank also descends thereupon, and under gravity and extension spring effect, piston also descends thereupon, expose the paddle hole on the cylinder body, the water in the water tank mainly in cylinder body top collar extension, paddle hole, enter water pipe.So like this, back and forth constantly, reach the water tank level control action.Owing to adopt the piston type combination brake switch and proporting, compare with ordinary ball valve, reached the liquid level can regulate, simplify water tank structure, stable strong, conserve water resource and raw-material purpose.

Below with reference to accompanying drawing model utility is described in further detail.

Fig. 2 is the sectional view that figure one removes ball float and connection chain.

Fig. 3 is the side view that figure one removes ball float connection chain and internally installed pull-spring.

Fig. 4 is the plan view that figure one removes ball float, connection chain and internally installed pull-spring.

Fig. 5 is the piston ring schematic representation.

Fig. 6 is the piston schematic representation.

Describe in detail according to detail and the working condition that the utility model proposes below in conjunction with Fig. 1.

With reference to figure one, this combination brake switch and proporting piston (5), cylinder body (8), the valve body (10) by ball float (1), connection chain (3), Dai Yousan road piston ring (7), one-way valve (12) is formed.Piston among the figure (5) is in the rising closed position.

Valve body (10) side one one-way valve (12), the acting as of one-way valve (12): when the hydraulic pressure in the combination brake switch and proporting was lower than hydraulic pressure outside the combination brake switch and proporting, one-way valve (12) was opened, otherwise, then under the effect of spring (14), close.The cylinder body (8) in valve body (10) hole of built-in generation (9), inboard, cylinder body (8) upper end open place studs with rubber ring (6), the built-in piston of cylinder body (8) (5), the outer top of piston (5) is for there being three road piston rings (7), and piston (5) internally installed pull-spring (16) links with cylinder body (8) bottom.When liquid level is lower than predetermined altitude, piston (5) drops to cylinder body (8) bottom under extension spring (16) and action of gravity, valve opening is when liquid level reaches predetermined altitude, piston (5) rises to cylinder body (8) top, valve closing under the effect of ball float (1).

Whole cylinder body (8) internal surface and piston (5) ramp should polish.

Claims (1)

1, one by ball float (1), the liquid level adjusting piston formula combination brake switch and proporting that connection chain (3), piston (5), cylinder body (8), valve body (10), one-way valve (12) are formed, it is characterized in that: valve body (10) side one one-way valve (12), the cylinder body (8) in valve body (10) hole of built-in generation (9), inboard, cylinder body (8) upper end open place stud with rubber ring (6), the built-in piston of cylinder body (8) (5), the outer top of piston (5) for having three road piston rings (7), piston (5) internally installed pull-spring (16) to link with inferior part of the cylinder block.
