Embodiment

[0029] like figure 1 As shown, it is an embodiment of the high temperature resistant valve of the present invention. This embodiment includes a valve body 1, the valve body 1 is a hollow rectangular structure, and its middle part is filled with a lining 2 made of refractory castable material. A vent hole 3 is opened in the middle of the lining 2, and a rotating shaft 4 runs through the vent hole 3, and a blade 5 is fixed on the rotating shaft 4, and the blade 5 is adapted to the vent hole 3. The rotating shaft 4 drives the vane 5 to rotate to realize the on-off of the valve. This inner lining 2 formed of refractory castable has excellent resistance to flex cracking and dynamic fatigue, relatively low coefficient of thermal expansion and contraction, simple construction, high temperature resistance not lower than 1000 degrees Celsius, and comprehensive performance is more obvious than other similar products improve. During the construction process, it is necessary to strictly...

Abstract

The invention provides a high-temperature-resistant valve, which solves the problems of complex structure and poor sealing performance of the valve in the prior art. The high temperature resistant valve includes a valve body, the interior of the valve body is filled with a lining made of refractory castable material, a vent hole is opened in the middle of the lining, a rotating shaft runs through the vent hole, and the rotating shaft A vane is fixed on the top, and the vane is adapted to the air hole, and the rotating shaft drives the vane to rotate to realize the on-off of the valve. The high temperature resistant valve of the present invention is simple in structure, easy to use, can guarantee good sealing performance in a relatively high temperature working environment, and has good practicability.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a high temperature resistant valve with simple structure, convenient use and good sealing effect. Background technique [0002] Ordinary gate valve products, due to structural material problems, cannot withstand high temperatures and have a short service life, which cannot meet long-term effective and stable use. Some manufacturers even add insulation blocks, fillers or high-temperature-resistant rubber for sealing, which cannot meet environmental protection requirements in high-temperature environments. The following are the problems that exist in a large number of commonly used gate valves at present: [0003] First of all, in terms of sealing performance, the use effect is not ideal. Due to the elasticity of the material and other reasons, the flatness that should be achieved during the construction process cannot be guaranteed, resulting in uneven deformation of the sealing s...
