Abstract
The utility model discloses an air evacuation valve with a float ball provided with an ejector pin. The air evacuation valve comprises a valve body and a valve deck, wherein a central through cavity is formed in the valve deck; a protection cover is arranged on a center-stepped cavity port at the top of the valve deck; a micro-scale air evacuation valve deck is further installed on the valve deck; the side wall on the lower cavity port of the through cavity of the valve deck extends upwards to form a stepped cavity seat; the top end of the float ball is connected with a vertical ejector pin; an air outlet is formed in an air nozzle which is connected with the bottom of the float ball; the float ball is pressed against the top of the stepped cavity seat, and the air nozzle at the bottom of the float ball is movably connected with a slide hole of the step cavity seat; a mounting seat is installed in the central through cavity of the valve deck; a guide rod is movably connected with the center of the mounting seat; and a valve clack is installed at the lower end of the guide rod, and central through cavities are formed at the centers of the guide rod and the valve clack. The air evacuation valve with a float ball provided with an ejector pin is simple in structure and easy to realize so as to evacuate air timely and quickly, and the falling back accuracy of the float ball is improved, so that the air evacuation effect is excellent.
Description
Technical field
The utility model relates to the outlet valve field, is specially a kind of outlet valve of ball float band push rod.
Background technique
Water heating system generally adopts water as the medium of transferring heat, usually be dissolved with certain air in the water, when water temperature raises, gas in the water can be separated from water gradually, and get together gradually formation large bubble even gas column, therefore, generally need in the water heating system to adopt outlet valve that the gas in the water is discharged.Outlet valve is generally by valve body be arranged on float in the valve body etc. and consist of, gas enters the valve body and makes the float of blocking the valve body lower portion accent float to realize exhaust from the valve body lower portion accent, and the complete rear float of exhaust falls after rise under Action of Gravity Field blocks the valve body lower portion accent again.Sometimes water is brought in the outlet valve during outlet valve exhaust of prior art, and water also can make float float, thereby cause outlet valve to lose efficacy, when vent valve float falls after rise simultaneously sometimes the position can be offset the valve body lower portion accent, also easily cause outlet valve to lose efficacy.
The model utility content
The utility model purpose provides a kind of outlet valve of ball float band push rod, easily intake to solve the prior art outlet valve, and the problem that deviation causes outlet valve to lose efficacy appears in float falling position.
In order to achieve the above object, the technological scheme that adopts of the utility model is:
A kind of outlet valve of ball float band push rod, comprise the valve body with cavity, and flange is tightly connected at the valve gap at valve body top, valve gap has the center cavity, the top of valve gap has center step accent, and on the center step accent of valve gap the protective housing of blocking center step accent is installed, the micro-exhaust valve body that is communicated with the valve body cavity also is installed on the described valve gap, it is characterized in that: described valve body cavity bottom has the lower accent of undergauge, described lower accent sidewall extends upwardly to and consists of step chamber seat in the valve body cavity, step chamber seat top center is provided with slide opening, also comprise the ball float that is arranged on the hollow in the valve body cavity, the ball float top is connected with vertical push rod, ball float bottom be connected with ball float in the valve that is communicated with, be provided with a plurality of air outlets on the valve sidewall, described ball float is pressed in seat top, step chamber and blocks the slide opening of step chamber seat under the self gravitation effect, and the valve of ball float bottom is slidingly mounted in the slide opening of step chamber seat, be installed with fitting seat in the cavity of described valve gap center, the fitting seat central slide is equipped with along the guide rod that vertically stretches in the valve body cavity, lower end of the guide rod is connected with flap, and guide rod, the flap center is provided with the center cavity that enters for ball float top push rod, and the top of described ball float push rod is aimed at and close guide rod, the bottom accent of flap center cavity.
The outlet valve of described ball float band push rod, it is characterized in that: seat top, described step chamber also is provided with ring sealing base, the ring sealing base end face is shaped to the cambered surface with ball float bottom shape coupling, described ball float is pressed on the ring sealing base, is slidingly mounted in the seat slide opening of step chamber after the valve of ball float bottom passes ring sealing base.
The utility model is simple in structure, is easy to realize.The valve of ball float bottom is slidingly mounted in the slide opening of step chamber seat, gas is introduced in the ball float during exhaust, make ball float float, valve also rises along with ball float, until expose from the seat of step chamber the air outlet of valve sidewall, so just gas can be discharged, moisture in the gas is in the valve uphill process simultaneously, can or not enter in the valve body because Action of Gravity Field flows out downwards, avoid because the problem that buoyancy of water causes outlet valve to lose efficacy.The center cavity of guide rail, flap stretches into for the push rod at ball float top, like this after the ball float come-up, utilize to cooperate between push rod and guide rod, the flap center cavity and realize the location, ball float can be fallen after rise along the direction of guide rod, flap and push rod location, can when falling after rise, deviation not occur in the position.The utility model can in time be realized degassing function rapidly, and the validity of Effective Raise ball float when falling after rise, therefore has preferably exhaust effect.
