Technical Field

The invention relates to an exhaust valve device, in particular to a precise composite intake and exhaust valve.

Background

The Chinese patent application publication No. CN104613207A discloses a 'pipeline exhaust valve', a valve body is arranged at the end part of a drain pipe, a water inlet and a water outlet which are connected with the end part of the drain pipe are arranged at the lower part of the pipeline exhaust valve, the pipeline exhaust valve comprises a gas collection device and a buoy exhaust device which are arranged in the valve body, the gas collection device is arranged at the lower part of the valve body, the float exhaust device is positioned on the upper part of the gas collecting device, the pipeline exhaust valve can collect and exhaust gas into a whole, and a gas collecting circular ring is arranged in the valve to concentrate bubbles in water flow passing through the valve and then discharge the bubbles, but the exhaust valve adopts the principle of the float and a lever, so that failure is easy to occur, in addition, when the air flow in the pipeline is overlarge, the float is easy to blow directly, so that an exhaust port is blocked, the exhaust port cannot be opened due to overlarge pressure difference between the inside and the outside, the reliability is poor, a Chinese utility model patent with the authorization publication number of CN206093156 discloses an 'pipeline automatic air inlet and exhaust valve', a float outer barrel is arranged in a valve body, a float ball is arranged in the float outer barrel, the top end of the float ball is provided with a float ball gland and a guide exhaust pipe, a plurality of guide exhaust pipe holes are arranged on the guide exhaust pipe from top to bottom, be equipped with the stand pipe of UNICOM's direction blast pipe in the middle of the top valve post of valve gap, be equipped with the exhaust inner tube on the valve post around the stand pipe, the exhaust violently pipe of UNICOM's exhaust inner tube is equipped with on the lateral wall at valve post top, can deflate rapidly through the outer barrel fence hole of floater when gas in the pipeline is too much, and also be equipped with the secondary vent hole through the centre of elastic sleeve when gas is less in the pipeline and go on deflating often, can also admit air rapidly when the pipeline produces the negative pressure, prevent that conduit from taking place to warp and breaking, the reliability is also stronger, but this kind of pipeline automatic air inlet and outlet valve's not enough has following several aspects:

firstly, the floater gland at the top of floater is the separation, and the direction blast pipe is easily lived by the incrustation scale and leads to malfunctioning after using a period of time, especially advances under the less condition of discharge gas volume, because the power that advances to exhaust and provide is very little, is rusted by the incrustation scale and leads to malfunctioning probability will increase.

Secondly, the floating ball seals the secondary vent hole on the elastic sleeve at the initial stage of rising, and the secondary vent hole on the elastic sleeve does not play the micro-exhaust role in reality.
