Manual Diaphragm Valve factory Plastic diaphragm valve is a special form of shut-off valve. The biggest difference between the plastic diaphragm valve and other valves is that it adopts a structure without a stuffing box; the rubber diaphragm can completely isolate the corrosive medium in the flow channel from all the driving parts, thereby eliminating the usual "running, emitting, dripping" of the valve. , Leakage" and other drawbacks. Specifications Connection type: Thread/Welding Pressure of work: 1.0Mpa Dimension standard: GB, BS, ANSI, JIS Working temperature: 鈮?0鈩? 鈮?00鈩? 鈮?20鈩? 鈮?50鈩?/p> Valve Body Material: Plastic UPVC, CPVC, PVDF, PPH Diaphragm Material: EPDM+F46/FEP(F46)/PFA Size available: DN15-DN100 The use characteristics and working principle of plastic diaphragm valve (1) The soft rubber diaphragm valve can cut off the medium. (2) Because rubber has a certain degree of corrosion resistance, it is usually promoted and applied as a corrosion-resistant material, and continues to this day. (3) The flow path is simple, has a "self-cleaning" function, and can be used for dirty media. (4) It is suitable for the transportation of corrosive media and the adjustment of the flow rate. The flow parts are assembled by RPP or PVDF injection molded parts. They have excellent corrosion resistance, easy operation and light weight, and can replace stainless steel valves. (5) The diaphragm of the seal is made of F46 or PFA, the number of folding resistance is 鈮?200 times, and the corrosion resistance is equivalent to F4. (6) The use of screw lifting structure, large opening and closing torque, and good stability. (The working principle of the plastic diaphragm valve is shown in the right picture) A. The valve flap is opened, and the fluid enters the valve body with small flow resistance. B. The valve flap slowly closes downwards, the diaphragm starts to deform downwards, and the torque of handwheel rotation is small. C. The valve is closed and there is no leakage. After the diaphragm and the valve seat conflict, there is no need to tighten it forcefully. How to maintain valves 1. Leakage of valve body and valve cover: reason: 1. The casting quality of iron castings is not high, and there are defects such as blisters, loose structure and slag inclusion on the valve body and the valve cover. 2. Day freeze cracking; 3. Poor welding, there are defects such as slag inclusion, non-welding, stress cracks, etc.; 4. The cast iron valve is damaged after being hit by a heavy object. Maintenance method: 1. Improve the casting quality, and carry out the strength test in strict accordance with the regulations before installation; 2. For valves whose temperature is below 0掳 and 0掳, they should be kept warm or mixed with heat, and the valves that are out of service should be drained of stagnant water 3. The welding seam of the valve body and bonnet composed of welding shall be carried out in accordance with the relevant welding operation regulations, and the flaw detection and strength test shall be carried out after welding; 4. It is forbidden to push or put heavy objects on the valve, and it is not allowed to hit cast iron and non-metal valves with a hand hammer. The installation of large-diameter valves should be provided with a bracket.Manual Diaphragm Valve factory website:http://www.zzvalvecn.com/diaph....ragm-valve/manual-di
