  1, observe the surface process.

  Good all-copper faucet its surface will have exquisite technology, generally after polishing, electroplating treatment, so the surface looks more crystal bright, in the purchase can be in the case of sufficient light to see the quality of its surface plating process, if it looks shiny as a mirror is a good indication of its surface process, if its surface looks less shiny, or etching, oxidation spots, etc., it is recommended not to Buy, because the plating process is not guaranteed, and good all-copper faucet surface plating and a certain thickness, at present, the international standard of faucet plating thickness is 8 microns, good up to 12 microns, and poor quality copper faucet surface plating is only 3-4 microns, so in the purchase to try to let the businessman to show the relevant data is good.

  2, observe the cross-sectional interface.

  Many copper faucets on the market are often copper plating treatment on the surface, and its internal material is not copper material, so in the purchase must pay more attention to carefully observe the faucet section interface whether the copper body material, so when you buy you can use a knife in the faucet section interface scrape to see how its internal material.

  3, faucet valve spool purchase.

  In the purchase of all-copper faucet must not forget to select its spool, good faucet spool is generally based on ceramic material, its sealing performance is good, wear-resistant, so in the purchase of faucet must ensure that its spool material, if bad selection, it is recommended to let the businessman to show relevant evidence, and the terms of purchase into the contract, in order to be prepared for the subsequent use of the process of protection.

        Kaiping all-copper faucet manufacturers

  4, more hand touching.

  In order to ensure that the faucet purchased for all-copper material, so in the process of purchase is recommended to touch the faucet surface with your hands as much as possible, and copper material after plating its products with a heavy feel with your hands, its surface resistance, if the touch up its surface is smooth, it means that it is not copper material, it is recommended not to buy.

  5, knocking to hear the sound.

  In the purchase of all-copper faucet, in order to determine whether its material is copper, so in the purchase of its surface can be tapped by hand, and then listen to the sound emitted by the buckle faucet, such as tapping sound crisp, it is stainless steel, such as tapping sound dull, it means that it is copper material.

  6, bubbler purchase.

  In the selection of all-copper faucet, also have to consider the quality of its bubbler, generally good bubbler using ABS environmentally friendly engineering plastic material, which effectively filters the sound of running water, so that the water flow produces more bubbles, water splash will not splash, but also to achieve the effect of energy saving, if its no bubbler or its material is not good bubbler faucet, it is recommended not to buy.

  7, check the accessories.

  In the purchase of all-copper faucet, you also need to check the accessories, good accessories are also generally made of copper, other materials, although the surface of the plating process, but in the process of use its color will become lighter and more yellow, and will also be ooze, affecting the use and also affect the beauty.

Analysis of main technical performance of brass valve in valve industry


Today, Xiaobian will analyze the main technical performance of brass valve from seven aspects: light performance, sealing performance, flow medium, opening and closing force and moment, opening and closing speed, action sensitivity and reliability, and service life. I hope it will help you to know the products of brass valve manufacturers.

Classification and characteristics of pneumatic ball valve


[student question] classification and characteristics of pneumatic ball valve? [answer] pneumatic ball valve can be divided into o-ball valve and v-ball valve. The o-ball valve adopts floating structure, the ball core is precision casting, the outer surface is plated with hard chromium, the valve seat is made of reinforced polytetrafluoroethylene, the port of flow is the same as the pipe diameter, the flow capacity is great, the flow resistance is very small, and there is no leakage when it is closed, it is generally used as on-off valve, especially suitable for high viscosity, v-ball valve adopts fixed structure, the ball core has V-notch, which can realize shearing. Fiber, granular media. According to different process equipment, pneumatic or electric actuator can be selected to form pneumatic ball valve and electric ball valve respectively. If the pneumatic ball valve is to achieve proportional adjustment, it must be equipped with valve positioner. If the electric ball valve is to achieve proportional adjustment, it must be equipped with electronic electric actuator or servo amplifier. From the material, it can be divided into: carbon steel ball valve, stainless steel 304 ball valve, 316 ball valve and copper ball valve According to the pressure, it can be divided into: high pressure ball valve and low pressure ball valve High pressure pneumatic ball valve: mainly used in oil, natural gas, hydraulic oil, construction machinery and other industries Low pressure pneumatic ball valve: mainly used in corrosive pipelines such as water! Precautions and model of knife gate valve in use: the opening and closing part of knife gate valve is ram, the movement direction of ram is perpendicular to the fluid direction, manual knife gate valve can only be fully opened and fully closed, and cannot be adjusted and throttled. The ram has two sealing surfaces. The two sealing surfaces of the most commonly used mode gate valve form wedge and wedge angle, which vary with the valve parameters, usually 50. The wedge-shaped knife gate valve RAM can be made into a whole, which is called rigid ram. It can also be made into a ram that can produce slight deformation, so as to improve its processability and make up for the deviation of the sealing surface angle in the processing process. This kind of gate When the plate is called elastic ram knife gate valve closed, the sealing surface can only be sealed by the medium pressure, that is to say, the sealing surface of the ram is pressed to the valve seat on the other side by the medium pressure to ensure the sealing of the sealing surface, which is self sealing. Most knife gate valves adopt forced sealing, that is, when the valve is closed, the gate shall be forced against the valve seat by external force to ensure the sealing of the sealing surface. This type of valve shall be installed horizontally in the pipeline generally. The above contents are sorted out according to the problems encountered in the actual work of the trainees for reference. If there are any problems, please communicate and correct them in time.
