Like the existing gate valve of Fig. 1; Comprise valve body 1 ', valve gap 2 ', valve plate 3 ', valve rod 4 ' and opening device 5 '; Said valve gap 2 ' is located at valve body 1 ' top; Valve gap 2 ' adopts flange to connect with being connected of valve body, and said valve body 1 ' part vertically offers the fluid passage 6 ' that connects medium, and said fluid passage has water intake 11 ' and water outlet 12 '; Said valve plate 3 ' is located between interior water intake 11 ' of valve body fluid passage and the water outlet 12 '; Said valve rod 4 ' one end passes valve gap 2 ' and is connected with valve plate 3 ', and said opening device 5 ' is located on the free end of valve rod 4 ', also is provided with the flange plate 7 ' that is connected usefulness with pipeline on two free ends of said valve body 1 ' periphery water intake and water outlet.During work, the keying that utilizes the up-down of flashboard to come control valve, thus realize switching on or off of pipeline medium.Its valve gap of above-mentioned gate valve adopts flange to connect with being connected of valve body, and flange connects and must connect the hole through a plurality of bolts, and fitting operation is complicated, the inconvenience dismounting, wastes time and energy, and is subject to the restriction in place during installation.
The model utility content
To the problems referred to above, the utility model propose a kind of simple and compact for structure, volume is little, installation and removal are laborsaving fast, do not receive place restriction, long service life, the novel flange gate valve of good seal performance.
For solving this technical problem; The utility model is taked following scheme: a kind of novel flange gate valve, comprise valve body, valve gap, valve plate, valve rod and opening device, and said valve gap is located at the valve body top; Said valve body part vertically offers the fluid passage that connects medium; Said fluid passage has water intake and water outlet, and said valve plate is located between interior water intake of valve body fluid passage and the water outlet, and said valve rod one end passes valve gap and is connected with valve plate; Said opening device is located on the free end of valve rod; The said valve body position that is connected with valve gap is provided with internal thread, and that end that said valve gap is connected with valve body is provided with the outside thread that is complementary with the valve body internal thread, and said valve gap is located at the valve body top through the external thread rotary on it.
Further improvedly be: be provided with stuffing box packing between said valve rod and the valve gap, and the below that is positioned at stuffing box packing between said valve rod and the valve gap also is provided with at least one O RunddichtringO.
Further improvedly be: said opening device is handwheel or handle.
Through adopting the aforementioned techniques scheme; The beneficial effect of the utility model is: this novel flange gate valve; Being connected between said valve body and the valve gap adopts and is threaded; Under the situation that does not change original design standard of valve and external dimension, just can link together gate valve body and valve gap quick mounting easily through thread connecting mode; Have simple and compact for structure, advantages such as volume is little, installation and removal are laborsaving fast, long service life, and it does not receive the place restriction when installing, requires low, easy to maintenance to the coaxality between pipeline.Further improvedly be: be provided with stuffing box packing between said valve rod and the valve gap, and the below that is positioned at stuffing box packing between said valve rod and the valve gap also is provided with at least one O RunddichtringO, through the effect that the O RunddichtringO reaches double seal is set; The sealability of valve rod is improved; Reinforced the sealing defence line of gate valve, the O RunddichtringO has also reduced the frictional force of valve stem seal face simultaneously, and keying moment is reduced; Has laborsaving, the good airproof performance of keying, the advantage of long service life.
