Self-pressure control valve for the occasion

Self-operated differential pressure control valve is not applicable to the heat source as the main variable flow control system, when the system takes the heat source as the main variable flow control (inverter, reduce the number of circulating pump, change the smaller circulating pump, etc.) to reduce the system flow, the tube Network pressure will be reduced, heat network near the end of the user due to the pressure becomes smaller, differential pressure valve will automatically open the valve spool to maintain the original pressure is constant, the flow changes are only remote users, remote users serious lack of traffic . Near-end users and remote users can not be the same as the total flow changes and can not maintain the balance of hydraulic conditions, heat network dynamic hydrodynamic imbalance. On the contrary, the circulating pump reduces the outdoor temperature, the need to increase the circulating water, the user does not change the valve opening, the user pressure differential pressure control valve due to self-control, so that users can not increase traffic. Therefore, self-operated pressure control valve is not applicable to the heat source for the variable flow control system. Self-operated pressure control valve for users to take the initiative to change the flow of heat network operation. Heat network flow changes depending on the user's heat requirements, heat source changes and regulation of the user-based, the user needs how much heat, the heat source to provide how much calories. When the user indoor temperature reaches the design value, the indoor thermostat automatically shut down small, the user back pressure decreases, the differential pressure increases, the differential pressure valve will work with the thermostatic valve, automatically close the valve port to constant user pressure. Then the inverter based on perceived user needs, automatic adjustment frequency pump operation, so as to achieve variable flow energy-saving operation. Users to take the initiative to change the flow of a prerequisite, the user must install thermostatic valves and other self-control device, heat inlet to install self-contained pressure control valve can be achieved. Indoor installation of thermostatic valve, heat inlet to install self-contained pressure control valve, heat pump circulating pump frequency control. This user-driven variable flow variable flow mode of operation is the future direction of development, but also the most energy-efficient. This article Keywords: control valve

Precast Concrete Magnet is configured with a big neodymium block magnet in to a steel house.the neodymium block magnet is very big of size which is very large.Magnet for precast concrete, is a magnetic tool to hold concrete formwork. There are two hex bolt and a round handle button on the top of the precast concrete magnet, the hex bolt is for fixed with adapter and handle button is for push to use.

How to use precast magnet box? People who use this magnet need to find some shuttering adapter to suit the precast magnet box onto the concrete framework, this framework could be made of plywood,wood, iron steel, aluminum... Then push the round handle button on the top, the block magnet in steel box will sink and contact and catch with iron steel part. After setting the magnet to the formwork,The concrete will be formed trimly just as the precast framework likes.

 If someone want to remove the concrete magnet, he need to find a crowbar and pry up the round handle button and the block magnet will return to its position and not catch the iron steel.

Using the concrete formwork magnet is very convenient, construction workers could build a concrete  formwork on a ground ,and fit two hex bolt with the adapter onto the  the concrete formwork. There is another means of using the concrete formwork magnet,workers could hold the concrete formwork on a hydraulic platform,build and stock the concrete walls,and using forklift and crane to carry the walls while using them.

What are the advantages of using precast concrete magnet in modern architecture construction? By using the concrete magnet, the concrete could form very trimly of sizes for building constructions. By using the concrete magnet, the construction process could be much quicker as workers could stock concrete walls and use these concrete walls to build architecture. The repute of the construction company will be much better and customer will happy to pay the money for the timely construction works. By using the magnet for precast concrete, there will be less concrete works in dangerous high situations, worker could finish their work more safely and construction could save more insurance cost and give higher salary to the workers.

By using concrete formwork magnet,the workers could save more time while build constructions, after using concrete formwork magnet, there will be less risk or danger during the constructing process. In a word, the concrete formwork magnet could enhance the speed of build while inform more security,the workers could make more money from the construction and businessman could earn more money from their business.

The concrete formwork magnet is strong magnetism,please keep the electrical product and card away from it,also, while using the concrete formwork magnet do not put your hand or feet or any part of body under the magnet,it will cause injure.
