Abstract
The utility model discloses a novel ball float type air valve. The novel ball float type air valve structurally comprises a movable baffle (1) with holes, fixing part screws (2), guide rails (3), a stainless steel floating ball (4), screw caps and a locking washer device (5), wherein the guide rails (3) are arranged inside the valve, and the guide rails and the floating ball are connected through the screw caps and the locking washer device. A floating ball hole (6), guide rail holes (7) and small exhaust vents (8) formed in the outer sides of the guide rail holes are formed in the middle of the movable baffle (1). The novel ball float type air valve is designed in order to achieve exhausting in two stages, in the initial stage of exhausting, air has high exhaust velocity, in the later stage of exhausting, the air has low exhaust velocity, and the structure can not affect the intake process.
Description
Technical field
The utility model relates to long apart from fields such as transmission & distribution Hydraulic Projects.
Background technique
Water delivery engineering, due to a varied topography, needs pumping plant, the gate valve arranged along the line, easily causes the unexpected variation of in-pipe flow speed, forms water hammer.And the considerable damage of water hammer accident makes protecting water hammer become indispensable key component in the water delivery engineering construction.At present, the protecting water hammer device mainly comprises surge tower, air valve, water-hammer arrester, air tank, controllable check valve etc.
Air valve is a kind of for preventing that pipeline from producing the Special valve of negative pressure in the water hammer process, and simple structure, less investment, easy for installation are widely used in engineering.But the conventional air valve is when solving the negative line pressure problem, and exhaust causes larger water hammer malleation often because the pass valve is too fast latter stage, to pipeline, brings side effect.
The utility model focuses on the internal structure of optimizing traditional float-ball type air valve, makes it in use, plays two graduated discharge effects, the first stage Quick air-discharge, second stage is exhaust at a slow speed, and two stages were controlled the running orbit of ball float in valve simultaneously, makes air discharge more stably air valve.
The model utility content
The utility model provides a kind of novel float-ball type air valve that guide rail is housed, and purpose is that air valve can carry out two graduated discharges when water hammer occurs, and the first stage is Quick air-discharge, and second stage is exhaust at a slow speed, reduces the side effect that the water hammer malleation is brought; Control the running orbit of ball float, the ball float ambient air pressure balance in maintaining valve simultaneously.
For achieving the above object, a kind of float-ball type air valve that guide rail is housed according to the utility model mode of execution is provided, on its structure, guide rail has been installed, i.e. removable baffle plate (1) with holes and guide rail (3).Open ball float hole (6) in the middle of removable baffle plate (1) with holes, respectively open some small de-air hole (8) in removable baffle plate (1) guide rail hole (7) outside with holes, the shape of small de-air hole (8) is not limit, guide rail (3) is two, be symmetrically arranged, between guide rail (3) and ball float (4), adopt cap screw and lock washer device (5) to be connected and fixed.
This guide rail (3) that float-ball type air valve of guide rail is housed is arranged in valve, fixing with cap screw and lock washer device (5) between ball float (4) and guide rail (3), ball float (4) connects and composes a mobile unit jointly with cap screw and lock washer device (5), and ball float (4) slides up and down in valve by guide rail (3).Removable baffle plate (1) with holes is arranged on ball float (4) top, can together slide up and down with ball float, fixed component screw (2) is installed on guide rail (3) top and in order to prevent removable baffle plate (1) with holes, can only arrives a certain position by down sliding, this positional distance air valve outlet bottleneck is not more than half of ball float (4) radius.
Ball float hole (6) diameter in the middle of removable baffle plate (1) with holes is less than ball float (4) diameter, and removable baffle plate (1) with holes is less than the area in the middle ball float hole of removable baffle plate (1) with holes (6) in the area sum of the small de-air hole (8) in guide rail hole (7) outside.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, the utility model is a kind of float-type air valve, comprising removable baffle plate (1) with holes, fixed component screw (2), guide rail (3), ball float (4), fixedly cap screw and the lock washer device (5) of ball float (4) and guide rail (3).
Air valve is connected with pipeline, air valve inner float ball (4) under normal state in the valve inner bottom part.When startup or termination of pumping, manifold pressure increases suddenly, in air valve, with pipeline connecting part air pressure, increase, now ball float (4) is subject to upwarding pressure and starts to rise, due to guide rail (3) being housed, ball float (4) central authorities in valve all the time in the process risen, the skew of having avoided the variation due to the valve internal pressure to produce, in valve, air is evenly discharged all the time fast, until ball float (4) rises to removable baffle plate (1) with holes, locates.When the air valve internal pressure and ambient pressure is poor while diminishing, the ball float hole (6) that air valve inner float ball (4) rises in the middle of removable baffle plate (1) with holes is located, because the aperture, ball float hole (6) in the middle of removable baffle plate (1) with holes is less than the diameter of ball float (4), ball float (4) can be fully by the sealing of the ball float hole (6) in the middle of removable baffle plate (1) with holes, now removable baffle plate (1) with holes rises together with ball float (4), in valve, air is discharged air valve by the small de-air hole (8) of removable baffle plate (1) both sides with holes, playing exhaust later stage air walks unhurriedly and discharges the effect of air valve.While in valve, with external air pressure, reaching balance, ball float (4) and removable baffle plate (1) with holes arrive the partition place of valve outlet port bottleneck, and now air no longer discharges in valve.
When the pressure in pipe is less than extraneous barometric pressure, the pipeline outer air enters into valve body by removable baffle plate (1) with holes, and now ball float (4) descends with removable baffle plate (1) with holes simultaneously.On the top of guide rail (3), fixed component screw (2) is installed, removable baffle plate (1) with holes drops to herein and stops gliding, and ball float (4) continues to descend, until valve body inner air and outer air pressure reaches balance.
