2022-07-15 Copper valve can bring a lot of convenience in the process of use, but in daily life, if it leaks, what is the reason?In fact, this leakage phenomenon is caused by a variety of reasons, not only because of the loss of media, but also the potential safety hazards to the surrounding equipment and pers

2022-05-04 The design concept of "clamp type" connection is to reduce "live joint" in concealed parts and increase "dead joint", so as to prevent all kinds of vibration and other environmental effects from leaving hidden water leakage.

2022-05-04 How many kinds of fire valves are there? Fire valve is used to control fluid flow, pressure and direction of the device referred to as valve. The controlled fluid can be liquid, gas, gas-liquid mixture or solid-liquid mixture. The valve is usually composed of valve body, valve cover, valve seat, opening and closing parts (disc, plug body, gate, butterfly plate, diaphragm, etc.), driving mechanism (stem and valve driving device driving it), sealing parts (packing, gasket, etc.) and fasteners, etc. The control function of the valve depends on the driving mechanism or fluid to drive the lifting, sliding, swinging or rotary movement of the hoist to change the size of the flow channel area.

2022-05-04 Brass materials are called special brass if they are a variety of alloys composed of more than two elements. Such as lead, tin, manganese, nickel, iron, silicon, copper alloy. Brass has strong wear resistance. Special brass is also called special brass, which has high strength, high hardness and strong chemical corrosion resistance. And the mechanical properties of cutting are also outstanding. Seamless copper pipe drawn from brass has soft quality and strong wear resistance. Brass seamless pipe can be used for heat exchanger and condenser, low temperature pipeline, submarine transportation pipe. Manufacture sheet, strip, bar, pipe, casting parts, etc. Copper content is 62% - 68%, plastic is strong, and pressure resistant equipment is manufactured.
