Volcanic rock material is a very popular new construction technology, but in the production, we must dry it according to its certain method, and fix the stone on the building through metal pendant to form a stone decorative curtain wall. Generally, the way of hanging stones can be divided into six types. Today, Xiaobian will give you a detailed introduction. First, the steel pin dry hanging method This method, also known as the pin method, is the earliest and most succinct method in the dry hanging stone process. The steel pin type is connected on both sides and connected on four sides. The structural feature is that two adjacent stone panels are fixed on the same steel pin, the steel pin is fixed on the connecting plate, and the connecting plate is fixed to the skeleton. Second, the back bolt type hanging method The volcanic rock material is bolted to the back of the stone. The anchor is used to connect the metal parts to the keel on the wall. It is a relatively advanced stone dry hanging process in the world. It is a post-cut anchor and a rear branch. The system together constitutes the dry hanging system of the curtain wall. Third, the trough type hanging method The principle is similar to that of the single-limb short-slot dry hanging method, except that the long-length card strip is used to open the groove. In the unit type stone curtain wall, this dry hanging method is more used. Fourth, small unit dry hanging method The detachable building curtain wall, which is connected by metal hooks and various single plates with metal hooks and columns and beams, is called a small unit building curtain wall. Although the stone in the small unit dry hanging method is connected to the skeleton through the aluminum alloy strip, the difference is that the adjacent stone is independent and connected with the skeleton (aluminum alloy main beam). This connection completely changes the traditional hanging. Physical properties, design methods, processing methods and construction techniques of stone curtain walls. Five, short-legged dry hanging method This method is an improved practice of short-sole single-slots. The two adjacent stone panels are fixed together on a "dry" shaped card strip. The "dry" shaped strips are also made of stainless steel or aluminum alloy, preferably fixed to the skeleton. Yes. Sixth, volcanic rock material single-limb short groove dry hanging method In this method, two adjacent stone panels are fixed together on a "T" shaped card strip, and the "T" shaped strip is made of stainless steel or aluminum alloy, and the strip is fixed to the skeleton. Valves are found in virtually every industrial process, including water and sewage processing, mining, power generation, processing of oil, gas and petroleum, food manufacturing, chemical and plastic manufacturing and many other fields.

People in developed nations use valves in their daily lives, including plumbing valves, such as taps for tap water, gas control valves on cookers, small valves fitted to washing machines and dishwashers, safety devices fitted to hot water systems, and poppet valves in car engines.
In nature there are valves, for example one-way valves in veins controlling the blood circulation, and heart valves controlling the flow of blood in the chambers of the heart and maintaining the correct pumping action.
Valves may be operated manually, either by a handle, lever, pedal or wheel. Valves may also be automatic, driven by changes in pressure, temperature, or flow. These changes may act upon a diaphragm or a piston which in turn activates the valve, examples of this type of valve found commonly are safety valves fitted to hot water systems or boilers.
More complex control systems using valves requiring automatic control based on an external input (i.e., regulating flow through a pipe to a changing set point) require an actuator. An actuator will stroke the valve depending on its input and set-up, allowing the valve to be positioned accurately, and allowing control over a variety of requirements.
