Metallurgical manufacturing of steel casting parts has strong adaptability and variability, and different chemical composition and organizational control can be selected to adapt to the requirements of various projects; mechanical properties and serviceability can be selected in a large range through different heat treatment processes, And has good welding performance and processing performance. In addition, the isotropy of the cast steel material and the overall structure of the cast steel parts are strong, thus improving the engineering reliability. Combined with advantages such as weight-saving design and short lead time, it has a competitive advantage in terms of price and economy.
In the investment casting industry, steel castings are the most used castings in the manufacturing industry, and are widely used in equipment, agricultural machinery, machining, and automobile industries. Metal castings can produce parts with complex shapes, but there are also requirements for the design of the product structure. In the case of meeting the requirements of use, it should also try to comply with the casting process. For example, in the structural design, care should be taken not to have thin walls, which may easily lead to dissatisfaction with pouring or product deformation; for example, try not to have sharp corners, try to use radian transitions; and try not to appear small and deep blind holes, It will cause great trouble for foundry sand cleaning. Of course, there are many other structural problems. We will improve and optimize the product structure according to the customer's drawings without changing the customer's functional use, so as to maximize the product qualification rate and production efficiency. In some cases where the structure cannot be changed, we will also perform some follow-up processing after casting according to actual problems, so that the expected results can also be achieved.

A variety of alarm valve applications and construction of the three major advantages
Alarm valve is the automatic sprinkler system to turn on or off the water, and start the alarm device. In sprinkler system, the alarm valve is a vital component, its role in three: turn on or off the water, the output alarm signal and prevent the water back to the water supply, and through the alarm valve on the system water supply and alarm Device inspection. Alarm valve according to the system is divided into different types of wet alarm valve, dry alarm valve and deluge valve. 1. Wet alarm valve for wet sprinkler system. Its main function is: When the nozzle is turned on, the wet valve can open automatically, and make the water flow into the hydraulic alarm to send the alarm signal. 2. Dry alarm valve for dry sprinkler system. Its valve flap divides the valve into two parts, the outlet side is connected with the system piping and the nozzle, the compressed air is filled in the inlet, and the inlet side is connected with the water source. Dry valve on both sides of the pressure and water pressure on the valve flap torque control valve flap closed and opened, generally can be divided into differential dry-type alarm valve and closed-type dry alarm valve two. 3. Deluge valve for rain sprinkler system, pre-action sprinkler system, water curtain system and water spray off system. The inlet side of this valve is connected to a source of water and the outlet side is connected to a system line and a showerhead, generally empty, only inflated in the preaction system. Deluge valve open by a variety of fire detection device control.
