Lianke Valve globe check valve factory for fire protection

(1) T-strainer are mainly divided into straight-through T-strainer , positive baffle T-strainer , and reverse-baffle T-strainer , Because this product is very similar to the word “T”,  so named as T-strainer. The so-called baffle strainer means that the inlet and outlet of the strainer are at 90°, so how to distinguish the positive and negative baffles, when the valve is not installed, we can judge the positive and negative baffles through the filter screen , If the fine mesh of the strainer screen is on the outside, this is the anti-baffle strainer, and the corresponding side is the inlet. If the fine mesh of the strainer screen is measured inside, this is the positive baffle strainer, and the corresponding side is the import.                (2) Of course, there is a simpler method, which is to distinguish its inlet and outlet positions through the flow direction arrows on the valve body.                

A-First of all, we need to understand the main components of the pinch valve, the valve body, hose, up and down the strip, the left and right guide rod, the size of the stem and handwheel.Main components such as picturesB-When we turn the handwheel clockwise, the big/small stem rotates at the same time to drive the upper and bottom pressing rod to move up and down along the guide rod, so as to press the sleeve to close, otherwise open.C-We operate the pinch valve need to pay attention to the following details.Because the bearing pressure of the sleeve is very low and the torque of the valve is very small, when closing the pinch valve, the operator can feel the right amount of resistance when rotating the handwheel to achieve the closing effect. Do not force and many people to assist the operation or use other tools to close to avoid damaging the sleeve and the inner parts of the valve.D-Advantages of pinch valve as below1-The pinch valve can be installed in the pipeline at will, don’t have flowing direction limited.2-The pinch valve maintenance cost is very low. we dont need to replace seat and packing, only need to replace the hose.3-Because the sleeve is consumable, so we need to replace the hose regularly. According to the number of switching, it is usually 3-6 months. When replacing the hose, put butter on the valve stem to lubricate it.4-We could choice the different material of sleeve according to the medium, for example, we use the NR if the medium is the abrasive materials, diluted acids,alkali &chemical application. We will choice the EPDM if the medium is industrial chemical applications.

From July 23 to 24, 2022, the expert review team of pressure pipeline components from Hangzhou Special Procuratorate visited our company Lianke Valve Co., Ltd. to comprehensively audit the "Special Equipment (TS) factory prefabricated pipe section" certification. After two days of strict review, the experts gave us many valuable opinions. Their rigorous work style and professional knowledge have benefited us a lot.Under the joint efforts of all LIANKE people, we have established a quality assurance system and compiled the quality Manual, Procedure Document, Management System, Operation Instruction and quality record form for the manufacturing of pressure pipeline components. The document level of the system is clear, and responsibilities and responsibilities are clear. The content of the manual, element control and process quality control basically cover the quality control link of the whole process of component manufacturing of the company, which conforms to the requirements of TSG07-2019 "License Rules for Production and Filling Units of Special Equipment".Lianke Valve Co., Ltd. mainly produces pipe clamp valve, fluorine lined ball valve, fluorine lined butterfly valve, fluorine lined diaphragm valve, fluorine lined gate valve, fluorine lined check valve, fluorine lined globe valve, fluorine lined basket filter, fluorine lined Y-type filter and various pipeline filters, welcome customers to consult and cooperate!
