High efficiency and speed exhaust valve

Abstract

The invention relates to a high efficiency and speed exhaust valve. A valve body is internally provided with a floating ball, and the upper part of the floating ball is fixedly provided with a guide rod; the guide rod extends out of a valve cover upwards, and is connected with the valve cover in an up-and-down sliding manner; a second rod is slidably connected with a U-shaped block; an auxiliary spring located between the two ends of the U-shaped block is fixed between the connection position between a first rod and the second rod, and the lower end of the U-shaped block, and a support frame is fixedly provided with a stop block located on the side, deviating from the opening of the U-shaped block; and the lower part of the side face, deviating from the opening, of the U-shaped block is provided with an inclined plane toward the opening direction of the U-shaped block downwards; the stop block is provided with a spacing hole with an opening facing the U-shaped block, and the interior of the spacing hole is slidably connected with a stop pin; the end, deviating from the U-shaped block, of the stop pin is in contact with the inclined plane, and the U-shaped block is provided with a control rod fixedly; and the upper inner wall of the valve cover is fixedly provided with a valve seat. The opening-closing time of the valve is shortened, and the service life of the valve is prolonged effectively; and the valve seat can be repaired or replaced when the valve seat is worn severely.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a high-efficiency high-speed exhaust valve. Background technique [0002] The exhaust valve is used in the exhaust of independent heating systems, central heating systems, heating boilers, central air conditioners, floor heating and solar heating systems. Because water usually dissolves a certain amount of air, and the solubility of air decreases with the increase of temperature, so in the process of circulation, the gas is gradually separated from the water, and gradually gathers together to form large water bubbles or even air columns, because there is water supplement, so the gas is often exhausted. The discharge of gas depends on the exhaust valve to discharge it. The exhaust valve generally uses a floating ball to realize automatic exhaust. The exhaust valve needs to be opened and closed frequently, and it is easy to cause wear at the valve core thimble, which will reduce t...

AI Technical Summary

Problems solved by technology

The exhaust valve generally uses a floating ball to achieve automatic exhaust. The exhaust valve needs to be opened and closed frequently, which is easy to cause wear at the thimble of the valve core, resulting in reduced sealing performance of the exhaust valve and water leakage. At the same time, the exhaust valve Generally, the volume is relatively large, and it is not convenient to install and use.
