Detailed Description
The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. Based on the embodiments only in the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present invention.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be implemented in other ways different from the specific details set forth herein, and one skilled in the art may similarly generalize the present invention without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.
As shown in fig. 1-2, an impurity filtering structure of an exhaust valve 1 acts on the exhaust valve 1, the exhaust valve 1 includes a valve cavity 10, an exhaust port 11 is formed above the valve cavity 10, a sealing ring 12 is fixed at the exhaust port 11, a floating ball 13 is placed inside the valve cavity 10, a short connecting pipe 101 is communicated with a side of the valve cavity 10, the other end of the short connecting pipe 101 is communicated with a three-way pipe 102, the other joint of the three-way pipe 102 is respectively communicated with a screw thread ball valve 103 and a filter 104, the filter 104 is vertically arranged, a long connecting pipe 105 is communicated above the filter 104, the long connecting pipe 105 is vertically arranged, and the upper end of the long connecting pipe is communicated with a. A filter screen 14 is arranged in the inner cavity of the valve cavity 10 and on the periphery of the floating ball 13, the bottom of the filter screen 14 is connected with the valve cavity 10 through a vibrating device 15, the vibrating device 15 comprises a vertically arranged vibrating spring 151, and a resistance plate 152 is inserted and fixed in the middle of the vibrating spring 151.
The structure can be used in the operation process of the exhaust valve 1, the threaded ball valve 103 is opened to observe the flowing medium, if the flowing medium is water, the function of the exhaust valve 1 is proved to have no problem, namely, the gas is exhausted from the exhaust valve 1; if gas is flowing out, the venting function of the venting valve 1 proves to be problematic, i.e. the gas cannot be vented by the venting valve. The method is simple and visual, and can greatly improve the safety of the pipeline and reduce the loss.
Moreover, along with the operation of the exhaust valve 1, the liquid level inside the valve cavity 10 is constantly changed, and the medium is constantly flowed through the filter screen 14, so that impurities are blocked outside the exhaust valve 1 by the filter screen 14; and in the flowing process, the vibration device 15 can vibrate along with the water flow, so that the whole filter screen 14 is driven to vibrate, and impurities are prevented from being attached to the filter screen 14.
