Embodiment Construction
[0027] A specific implementation of the one-way control exhaust valve of the present invention is given below. The one-way control exhaust valve of the present invention is as follows: figure 1 As shown, it includes a gas inlet 1 and a gas outlet 2, the gas inlet 1 is used to connect with the pipeline, the gas outlet 2 communicates with the outside atmosphere, the gas inlet 1 is provided with a sealing ball 3, and the sealing ball 3 The gas inlet 1 is isolated from the external atmosphere, the sealing ball 3 is connected to a push rod 4, and the push rod 4 is controlled by an electronically controlled swing mechanism, where the electronically controlled swing mechanism is a central control lock 5, The electronically controlled pendulum mechanism can control the push rod 4 to drive the sealing ball 3 to move so that the gas inlet 1 communicates with the outside atmosphere.
[0028] In this embodiment, the electronically controlled pendulum mechanism is a central control lock 5,...

The invention discloses a one-way control exhaust valve, which comprises a gas inlet and a gas outlet, wherein the gas inlet is connected with a pipeline; a sealing ball is arranged at the gas inlet; and the gas inlet is isolated from outer atmosphere through the sealing ball. The exhaust valve is characterized in that: the sealing ball is connected with a push rod; the push rod is controlled by an electrically-controlled oscillating bar mechanism; and the electrically-controlled oscillating bar mechanism can be used for controlling the push rod to drive the sealing ball to move, so that the gas inlet is communicated with the outer atmosphere. The technical problem that an automatic exhaust valve only can automatically exhaust according to internal air pressure and atmosphere but cannot meet requirements under other conditions in the prior art is solved, and the exhaust valve is a controllable one-way control exhaust valve.
Description
technical field [0001] The invention relates to an exhaust valve, in particular to a one-way control exhaust valve. Background technique [0002] The exhaust valve is an exhaust device installed in the water tank or pipeline system. In the water tank or liquid pipeline system, the gas pressure in the system will change due to drainage, water intake or temperature changes. In order to ensure the normal operation of the system, it is necessary to Exhaust or intake treatment. For example, in a large water tank or water pipe, the internal gas pressure increases when water enters, and exhaust gas is required to ensure normal intake. [0003] Chinese patent document CN201513613U discloses an automatic intake and exhaust valve. A conduction pipe is arranged on the water tank. The upper end of the conduction pipe communicates with a valve body. An air intake steel ball, an exhaust round hole is set on the inner wall of the valve, and the position of the exhaust round hole is highe...
