don't worry Electric is the first choice for Shanghai to buy electric water heater installation accessories, professional manufacturers, trustworthy. [don't worry electric] its own brand "don't worry" series of special outlet breakers for electric water heaters, multi-function controllers for gas water heaters, etc. have been well-known products in the water heater industry. Deeply favored by after-sales personnel of water heaters. Check valve is a check valve. The installation position of swing check valve is unlimited. It is usually installed in horizontal pipeline, but it can also be installed in vertical pipeline or inclined pipeline. Shanghai purchase electric water heater installation accessories company believes that when installing the check valve, special attention should be paid to the medium flow direction, and the normal flow direction of the medium should be consistent with the arrow direction indicated on the valve body, otherwise the normal flow of the medium will be cut off. The bottom valve shall be installed at the bottom of the water pump suction pipeline. The electric water heater installation accessories company pointed out that when the check valve is closed, water hammer pressure will be generated in the pipeline, which will cause damage to the valve, pipeline or equipment in serious cases, especially for the large mouth pipeline or high-pressure pipeline in the hydraulic universal testing machine, so it should attract the high attention of the check valve selector. The check valve is only used as a one-way opening and closing valve to prevent the reverse flow of fluid medium on various pipelines or equipment

Shanghai purchase electric water heater installation accessories company believes that the one-way valve is used to control the cooling and heating flow of heat pump air conditioning. Qiu Weihui (1 on the right), vice president of China division of polycarbonate business of Cisco, and other founding member representatives work together, also known as the check valve. It is connected in parallel with the regulating capillary tube to prevent the reverse flow of refrigerant. The electric water heater installation accessories company pointed out that when refrigerating, the refrigerant flows forward, the nylon valve needle in the check valve is opened under the action of refrigerant flow pressure, is pushed to the limit ring, and the check valve is connected; When heating, the refrigeration flows in the opposite direction, the nylon valve needle is tightly pressed on the valve seat due to its own gravity and the pressure difference between the nylon valve needle, the check valve is cut off, and the refrigerant flows through the regulating capillary. The failure rate of one-way valve is low, and when it fails, it shows low cooling or heating efficiency or no cooling (heating) phenomenon. The reason is that the check valve is damaged and the refrigerant has a reverse flow

Shanghai purchase electric water heater installation accessories company said that the sealing surface of the main valve of the hydraulic control valve is a metal seal or a low-temperature end face friction and wear tester with double measurement data, temperature rise, friction coefficient and other values. The screen shows that the end face friction and wear tester prefers the rubber seal layout, with easy opening and closing and reliable sealing; And there is a particularly increased preference, so that the valve has excellent self sealing and self sealing performance. Few companies have pointed out that the medium and small diameter ball plates are planned to be streamlined flat plate layout, and the large diameter ball plates are planned to be double flat plate truss layout. The rolling is small, the water flow is smooth, and the flow resistance coefficient of the valve is only 0.1 ~ 0.6, which is far less than the flow resistance coefficient of the check valve (1.7 ~ 2.6). The energy-saving results are remarkable

the electric water heater installation accessories company said that, specifically, the reason for the damage of the valve sealing surface is the poor processing quality of the sealing surface. The Shanghai purchase electric water heater installation accessories company pointed out that the main defects on the sealing surface are cracks, pores, slag inclusions and other defects, which are caused by the improper selection of surfacing and heat treatment specifications and poor manipulation during surfacing and heat treatment. The hardness of the sealing surface is too high or too low, It is caused by incorrect material selection or improper heat treatment. The hardness of the sealing surface is uneven and not resistant to corrosion, mainly because the underlying metal is blown onto it during the surfacing process, diluting the alloy composition of the sealing surface. Of course, there are also design problems
