Embodiment Construction

[0027] The following examples can enable those skilled in the art to understand the present invention more comprehensively, but the present invention is not limited to the scope of the described examples.

[0028] like Figure 3-Figure 8 A new type of blocking valve is shown, including

[0029] A valve body 11, the valve body 11 has a flow channel 12 for the flow of the medium, and at the same time, the valve body 11 also has a liquid inlet and a liquid outlet connected to the flow channel 12 respectively.

[0030] A bonnet 13, the bonnet 13 is installed on the right end of the valve body 11 and cooperates with the valve body 11, and has a groove on the valve body 11 for the installation of the bonnet 13, between the bonnet 13 and the valve body 11 A sealing ring 15 is also provided, and the upper end of the valve cover 13 is fixed to the valve body 11 through the cover plate 14, and the cover plate 14 and the valve cover 13 are fixed by bolt connection, and an eyebolt 16 is ...

Abstract

The invention relates to a novel plug valve, which comprises a valve body, a valve cover, and an opening and closing assembly. A flow channel for a medium to flow is arranged in the valve body, and meanwhile, a liquid inlet and a liquid outlet communicating with the flow channel are further formed in the valve body; the valve cover is arranged on the right end of the valve body and is mutually matched with the valve body, meanwhile, a groove for installing the valve cover is formed in the valve body, and the upper end of the valve cover and the valve body are fixed through a cover plate; and the opening and closing assembly comprises a valve seat arranged on the valve body and a plug board located in the valve body, a sealing surface of the valve seat and a sealing surface of the plug board jointly form a sealing pair, and the plug board is arranged in the valve body through a swing mechanism. The novel plug valve provided by the invention has the advantage that by adopting a working mode of swinging the plug board, the switchover of two different working conditions can be realized without the need for repetitively disassembling and assembling parts, so that convenience is realized.

Description

technical field [0001] The invention relates to a plugging valve, in particular to a new type of plugging valve which can switch between hydraulic test and normal working conditions without repeatedly dismantling parts. Background technique [0002] As one of the most important cut-off valves, plugging valve plays an important role in the fields of electric power and aerospace. As an important component of thermal power generation equipment, the blocking valve realizes the functions of medium transmission and cut-off, and its sealing performance directly affects the safe and reliable operation of thermal power generation equipment. Studying the influencing factors and influencing laws of the sealing characteristics of typical plugged valves has guiding significance for the structural design of valve sealing pairs, so as to improve the sealing performance and reliability of valves. [0003] At present, traditional plugging valves such as figure 1 As shown, it includes a val...
