Abstract
The utility model relates to a float piston valve, which is suitable for closed or open liquid storage containers with all kinds of capacity. A piston valve is connected with a float to constitute the float piston valve, and the piston valve is composed of a valve body and a valve plug. The valve body is a multi-way pipe, and water enters the valve body from an upper end port and flows out from a side surface port. The inner part of the pipe hole of the lower end of the valve body is sheathed with the valve plug in a sliding mode, and the upper end head of the valve plug is provided with a conical lug boss which is matched with the neck port of the conical surface in the cavity of the valve body, so a gate flow sealing surface is formed. The lower end of the valve plug is connected with the float, and the valve plug is pushed through the buoyancy of the float to automatically seal the valve cavity neck port gate stream. The utility model has the advantages of simple structure, reliable control of gate flow, convenient maintenance and installation and low cost, and is not easily damaged and does not even need maintaining.
Description
The utility model relates to a kind of fluid valve, and particularly the fluid Automatic slucie valve is mainly used in the small-sized and Large Storage Tanks water container in family and public place, also can be used for industry storage liquid container automatically.
Existing float valve, the used float valve of water closet and roof tank for example, its structure adopts lever drives valve plug, and the lever the other end connects firmly ball float, and the lever middle part is with the moving fulcrum bar that is connected and fixed, and fixing rod is fixed on the storage liquid container wall.Because ball float drives valve plug by leverage, damage easily, cause out of control and can not automatic brake stream storage liquid, and install, maintenance is all inconvenient.
Technical solution of the present utility model is the buoyancy aid piston valve, connecting buoyancy aid by piston valve constitutes, piston valve is made of valve body and valve plug, valve body is many logical tubular bodies, the valve body upper end mouth of pipe is a water intake, the valve body side mouth of pipe is a water outlet, the valve plug sliding sleeve is in the valve body lower end pore, the valve plug lower end is stretched out outside the valve body lower end aperture and is connected with buoyancy aid, in the valve body chamber, a up-small and down-big conical surface eck is arranged between the valve body upper end mouth of pipe and the side mouth of pipe, the valve plug upper end is in the valve body chamber, there is a up-small and down-big conical boss its termination, and the eck conical surface is corresponding in valve plug boss conical surface and the valve body chamber coincide, and uses to constitute piston valve lock stream sealing surface.
Description of drawings is as follows:
Fig. 1 is the buoyancy aid piston valve construction schematic representation that has a buoyancy aid
Fig. 2 is the buoyancy aid piston valve construction schematic representation that has a plurality of buoyancy aids
The utility model further specifies as follows in conjunction with specific embodiments referring to accompanying drawing.
Embodiment 1 is the buoyancy aid piston valve of single buoyancy aid, connecting a buoyancy aid by piston valve constitutes, piston valve is made of valve body ［ 1 ］ and valve plug ［ 8 ］, valve body ［ 1 ］ is a logical tubular body more than, its upper end mouth of pipe ［ 2 ］ is a water intake, valve body ［ 1 ］ the side mouth of pipe ［ 5 ］ is a water outlet, valve plug ［ 8 ］ sliding sleeve is in valve body ［ 1 ］ lower end pore ［ 6 ］, valve plug ［ 8 ］ lower end is stretched out outside the pore ［ 6 ］ and is connected with buoyancy aid ［ 7 ］, between valve body ［ 1 ］ the upper end mouth of pipe ［ 2 ］ and the side mouth of pipe ［ 5 ］, in the valve body chamber a up-small and down-big conical surface eck ［ 3 ］ is arranged, valve plug ［ 8 ］ upper end is in the valve body chamber, there is a up-small and down-big conical boss ［ 4 ］ its termination, boss ［ 4 ］ conical surface is corresponding with neck ［ 3 ］ conical surface to coincide, and uses to constitute piston valve lock stream sealing surface.
On conical boss ［ 4 ］ the side conical surface of valve plug ［ 8 ］ groove around boss ［ 9 ］ is arranged, setting-in annular sealing strip ［ 10 ］ in the groove ［ 9 ］, Stamping Steel Ribbon is the circular section rubber strip.
Buoyancy aid ［ 7 ］ is the hollow thin walled shell, and two ends are sphere, the middle circle cylinder.
On conical boss ［ 4 ］ the side conical surface of valve plug ［ 8 ］ groove around boss ［ 9 ］ is arranged, setting-in annular sealing strip ［ 10 ］ in the groove ［ 9 ］, Stamping Steel Ribbon is the circular section rubber strip.
Buoyancy aid ［ 7 ］ is the hollow thin walled shell, and two ends are sphere, the middle circle cylinder.
The utility model advantage is that it is simple in structure, and automatic brake stream and unlatching control are reliable, not fragile, and installation, maintenance conveniently even need not keeped in repair, and be cheap, applicable to the closed of various capacity or top open-type storage liquid container.
