Overview of static balance valve and dynamic balancing valve works and differences

Dynamic balance valve is divided into flow (flow dynamic control valve) and pressure control two, according to the actual needs of choice. Dynamic balance valve is used to solve the balance of branch pressure balance caused by the frequent action of temperature control valves at the end of each station. The static difference is that: static balance valve need to be a one-time debugging through a dedicated smart meter lock, the system's total water control in a reasonable range Dynamic balance valve is divided into flow (flow rate dynamic control valve) and differential pressure control, according to The actual needs of choice. Dynamic balance valve is used to solve the balance of branch pressure balance caused by the frequent action of temperature control valves at the end of each station. The static difference is that static balance valve needs a dedicated smart meter after a one-time debugging lock, the system's total water control within a reasonable range, but each change requires re-locking the valve through the instrument, the dynamic is self-force Do not have to be so troublesome, relying on the media network itself to adjust the media pressure changes automatically constant flow, the static cost of the project to be slightly cheaper. Dynamic balancing valve works: By changing the balance valve spool flow area to adapt to the valve before and after the change, so as to achieve the purpose of controlling the flow. Dynamic balance valve can be installed in the water supply pipe can also be installed in the return pipe. When the system fluid working pressure exceeds the allowable working pressure radiator, for safety reasons, the dynamic balance valve should be installed in the water supply pipe. Static balance valve, also known as balancing valve, manual balancing valve, digital lock balance valve, two-position control valve, used to solve the pipeline design branch pressure balance problem. Static balancing valve works by changing the valve core and seat gap (opening), to change the flow resistance through the valve in order to achieve the purpose of regulating the flow of its object is the system resistance, to the new amount of water In accordance with the design of the proportion of balanced distribution, each branch at the same time increase or decrease at the same time, still meet the needs of the current part of the climate load demand, play a role in thermal equilibrium. Static balance valve can be installed in the water supply pipe can also be installed in the return pipe, generally to be installed in the return pipe, especially for high temperature loop, for ease of debugging, but also installed in the return pipe, the installation of the balance valve No need to set stop valve for return pipe. Both static balance valve or dynamic balance valve, itself is the impedance element, especially the dynamic balance valve, requiring the system when the optional pump must consider the balance valve caused by the additional head.

Construction Hoist Part

Construction hoist is vertical transport machinery driving by pinion and rack, mainly used on construction site for transportation of personal and materials. As a permanent or sub-permanent external elevator, it also applies to store house, dock, high tower, high chimney, etc.

There are single cage and double cages hoist. According to the need gets rid of one cage of double cages the hoist will be changed to single cage hoist. SC Construction Hoist is equipped with reliable electrical and mechanical safety device. It is efficient and safety vertical transporting equipment.

BQ supplying all kinds of construction hoist spare parts, including Construction Hoist Mast Section, Passenger Hoist Cage, Construction Hoist Anchorage Frame, Anti Fall Safety Device, Construction Hoist Overload Protector, Construction Hoist Reducer, Sliding Contact Line, Construction Hoist Motor, Passenger Hoist Rope Pulley, Construction Hoist Roller, Electromagnet Brake, etc.
