New bypass hydraulic control pressure relief valve improved after the market

It is reported that the design and manufacture of three diameter 80mm, 150mm, 300mm pressure relief valve, nominal pressure 1.6MPa, used in tap water, metallurgical cooling circulating water, petrochemical cooling circulating water pipe system, after nearly 1 year of operation proved that the valve Flexible action and adjustable closing time. As to complex pipe network system, the water hammer elimination effect is good, and the problems of long time of slow closing of the two-stage shut-off valve and reversal of backwater impact are solved completely. Description of valve structure and performance of the design method is feasible, accurate parameter selection. Bypass hydraulic control relief valve installed in the main pipeline Check Valve outlet side of the bypass pipe, with the check valve used in conjunction with the use of pressurized liquid in the pipeline to achieve the drive and automatic control, completely solve the traditional two-stage shutdown Valve to eliminate water hammer pressure when the pump rotor rotor parts to reverse the problem. Due to its adjustable closing time, it is applicable to a variety of complex pipelines to eliminate water hammer pressure. It is a new type of pressure relief valve with extended application value.

Mechanical Diaphragm Dosing Pump, is characterized by the mechanically driven diaphragms which have replaced the previous structure type,it's an Easy Operation Dosing Pump. Which means: the working chamber of the pump liquid end is caused from the diaphragm, the diaphragm periodic motion produces the elastic deformation, throught this deformation the diaphagm will be reciprocating motion and reach the pump quantitative dosing, the accuracy of this dosing will be + 1%. The mechanical diaphragm is for precise and accurate metering control, operation remains reliable even when the main voltage fluctuations, the character of hermetically sealed and resistant materials allow diaphragm dosing pumps to convey aggressive media with ease, which also make it convenience to used in chemical and petrochemical, pharmaceutical, cosmetic and food production industry. then the adjustment of the stroke length allows the operator to make accuracy modulation. However, there are different control types which make easy process integration.
