1. The urban construction system usually uses a large number of low-pressure cast steel gate valves and the development of environmental protection and energy conservation. The low pressure of using iron gate valves gradually turns to green plastic sheet valves, sanitary grade pipe fittings, transition metal sealing butterfly valves and line sealing butterfly valves. The pipeline for the development of oil and gas projects requires a large number of planar gate valves and ball valves. The above is a detailed introduction of the role of cast steel gate valves in urban development and construction.

The graded toothed roller crusher is powered by two electric motors,
which are decelerated by a reducer and then drive two parallel mounted toothed
rollers to rotate in opposite directions. When the material falls between the
two rollers of the graded crusher, the material is first screened with spiral
teeth or knife shaped teeth. Particles smaller than the discharge particle size
directly pass through without crushing, and enter the discharge chute. Under
the combined action of vertical stress or shear force, large pieces of material
are split by the teeth of the toothed roller Shearing and stretching are broken
and discharged from the discharge port.
Advantages of Powerful Double-Toothed Roll Crusher
1. The grading crusher crushes materials by shearing and stretching,
resulting in uniform particle size of the product after crushing, with low
levels of over particle size and overfilling.
2. The transmission device has a compact structure, flexible
operation, low noise, and high safety.
3. Adopting a hydraulic coupling and a "utility model"
safety coupling for dual overload protection, it is safe and reliable.
4. Adopting a "utility model" crusher tooth plate, the
tooth plates are arranged in a spiral manner, with good wear resistance and
long service life.
5. The body adopts a modular design, and the combination of various
units is convenient and fast, making it easy to disassemble and transport
underground and coal buildings.
6. The overall height is low, suitable for working environments with
limited space.
7. According to user requirements, speed sensors and PLC programming
can be installed to control the working status of monitoring equipment,
achieving remote control.
8. Adopting an automatic oil supply system to extend the service
life of bearings and reduce the intensity of daily maintenance work.

2. The other side of energy development is energy saving, so from the perspective of energy conservation, development of steam traps, and high development of subcritical and supercritical parameters.
3. The large-scale development of power station construction requires large-caliber, high-pressure relief valves and pressure reducing valves, as well as the need to quickly open and close valves.
4. The needs of the package engineering, supply valve through a single species species and specifications. Valve manufacturers need to provide a valve project all the increasing trend.
