Problems solved by technology
[0003] Butterfly valve not only has simple structure, small size, light weight, low material consumption, small installation size, small driving torque, easy and fast operation, but also has good flow regulation function and closing and sealing characteristics. Currently common butterfly valves, valves The seat and the valve body adopt an integral structure with interference fit. In order to ensure the sealing performance, they cannot be replaced. If there is leakage and damage, the valve body and the valve seat can only be replaced together. The maintenance cost is too high, and it is difficult for the manufacturer to recycle. Reuse, causing a large number of casting valve bodies to be scrapped, the cost is too high

Embodiment Construction
[0028] In order to understand the present application, the present application will be described in connection with the accompanying drawings and specific embodiments.
[0029] It is to be understood that the words "first", "second", "third" are used to limit the components, just to facilitate the difference of the above components, if not separately declared, there is no special meaning, Therefore, it is not understood to limit the scope of the present application. In the description of the present application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise specifically defined.
[0030] refer to figure 1 In this embodiment, the two-way equipped ultra-low temperature pure metal sealed butterfly valve, including: valve body 1, valve seat 2, valve stem 3, butterfly 4, and combined sealing structure 5. The valve seat 2 is located in the valve body 1. The valve stem 3 is located in the valve body 1, and through the valve seat 2, the valve stem 3...

The invention discloses a bidirectional isobaric ultralow-temperature pure metal sealing butterfly valve. The bidirectional isobaric ultralow-temperature pure metal sealing butterfly valve comprises a valve body, a valve seat, an energy storage type sealing ring, a four-piece ring, a compression spring and the like, the valve body and the valve seat are designed in a split mode, so that the valve seat is provided with piston follow-up for compensation sealing, replacement is convenient, and the maintenance cost is reduced; meanwhile, an energy storage type sealing ring combined sealing structure is arranged between the valve body and the valve seat, and the group of sealing materials, namely high-temperature-resistant materials, are replaced, so that an ultralow-temperature butterfly valve is converted into a high-temperature-resistant two-way pressure butterfly valve, and the application range of the valve is greatly widened through conversion of the combined sealing structure; and different main body materials can be selected to meet the use under any working condition. Due to the fact that the butterfly valve has the advantages of being small in size and light in weight, and due to the two-way isobaric design, other valve types are replaced, cost is reduced, and energy is saved.
Description
Technical field [0001] The present application relates to the field of valve technology, in particular to a two-way equipotent ultra-low-temperature pure metal sealed butterfly valve. Background technique [0002] Butterfly valve is also a turbable valve, is a simple adjustment valve that can be used for the switch-controlled butterfly valve controlled by the pipe medium means a disc, rotating around the valve shaft to achieve open and closing. A valve, valve can be used to control air, water, steam, various corrosive media, mud, oil, liquid metal, and radioactive medium and other types of fluids. The cut and throttling effects are mainly cut on the pipeline. Butterfly valve The shutter is a disc-shaped butterfly plate that rotates around its own axis to achieve the purpose of opening and closing or adjustment. [0003] Butterfly valves are not only simple, small, lightweight, material consumption, small installation size, small driving force, easy operation, fast operation, can ...
