Abstract
The utility model provides an automatic exhaust valve used for a water supply system, comprising a valve body, a valve cover and a sliding block, wherein the sliding block is arranged in the valve body in a floating way; the valve body is internally provided with a fixed plate; the sliding block is connected with a fixed baffle plate by penetrating through a connecting rod of the fixed plate; the valve cover is provided with an exhaust channel matched with the fixed baffle plate of the sliding block as well as an exhaust port communicated with the exhaust channel; and the bottom of the valve body is also provided with an interface connected with a water pipe. When gas is generated in the water pipe of the water supply system, the gas enters the exhaust valve, so that the sliding block in the valve body descends and then the gas can be exhausted through the exhaust channel and the exhaust port; and after the gas is exhausted, the sliding block ascends under the action of buoyance to close the exhaust channel, therefore the function of automatic exhaust is realized.
Description
Technical field
The application relates to a kind of automatic control pressure vent, relates in particular to a kind of automatic control pressure vent that is used for the water heating system water system.
Background technique
In water system commonly used, for example in the water system of water heating system, can use outlet valve usually, be used for the air in the discharge conduit.The form that original outlet valve adopts spring to be connected with slide block usually, thus make slide block after exhaust, to reset, however this outlet valve can be received the restriction of telescopic spring usually, and get rusty easily, working life is short.
The model utility content
The purpose of this utility model provides a kind of automatic control pressure vent, and the mode that this automatic control pressure vent adopts floating slider can realize automatic vent under the situation that does not adopt spring members.
The technical solution of the utility model is as follows:
A kind of automatic control pressure vent that is used for water system, comprise valve body, valve gap and slide block, wherein, the slide block floating ground is arranged at valve inner, is provided with fixed plate in the valve body, and slide block is connected with fixed dam by the connecting rod that passes fixed plate, valve gap has exhaust passage of matching with the fixed dam of slide block and the relief opening that is communicated with the exhaust passage, and the bottom of valve body is provided with the interface that is connected with water pipe.
Wherein, slide block is made of plastics.
Wherein, described valve body all is by being threaded with described valve gap and described valve body with water pipe.
The technique effect that the utility model is obtained:
Automatic control pressure vent in the utility model, when gas occurring in the water pipe in the water system, gas enters outlet valve makes the slide block in the valve body descend, thereby gas can be discharged by exhaust passage and relief opening, discharging rear slider when gas rises under buoyancy function, close the exhaust passage, thereby realize self-bleeding function.
