Water seal valve for working pressure 1.6 ~ 10.0MPa, operating temperature 0 ~ 425 ℃ thermal power plant backwater condensing system and oil, chemical and atmospheric requirements of the pipeline to cut off or connect the media, the applicable medium: water, oil Products, steam and non-corrosive gases. First, the characteristics and uses 1, S / Z series of opening and closing flexible, rapid, reliable seal, usually with double gate elastic seal; 2, the product structure is simple, compact and reasonable, easy maintenance, long service life; 3, The opening and closing device for the pipeline must be in the fully open or fully closed state and can not be used for regulating the flow rate. 4. There are two ways of connecting the valve: flange and welding. The driving mode is manual and electric, and the structure is complicated. Valve sealing surface configuration can be divided into wedge gate valve and parallel gate valve, wedge gate valve single gate type, double gate type and elastic gate type. Parallel gate-type gate valve can be divided into single gate and double gate type. According to the thread position of the stem division, can be divided into Ming rod valve and dark rod gate valve two. Second, the design and manufacture of water seal valve design and manufacture: GB12234 flange size: GB9113JB7490 pressure temperature: JB / T74GB9131 structure length: GB / T12221 test and test: JB / T9092GB13927 Third, the main performance specifications Nominal pressure Body strength test 1.01.62.54.06.410.0 Sealing test 1.52.43.86.09.615.0 Sealing test 1.11.82.84.47.011.0 Gas seal test 1.11.82.84.47.011.0 Scope of application Product type Applicable temperature (℃) Applicable medium Carbon steel type ≤425 water, steam, oil, non-corrosive gas alloy type ≤540 Fourth, the main parts and materials Product Type Part Name Valve body, valve cover, bracket Valve stem gate, flap, sealing surface Seat sealing surface Stem Nut Packing Alloy Steel (I) WCBCr5Mol20Cr1Mo1VA Cobalt Base Alloy Carbide Aluminum Bronze Flexible Graphite Carbon Steel Type (C) WCB1Cr13 or 2Cr13Cr13 Type Stainless Steel or Carbide Stainless Steel Aluminum Bronze Flexible Graphite
LED Track Line Lights
What is linear track lighting?
LED Track line lights are commercial track lights, suitable for supermarkets, stores, exhibitions and other places. Combinable with Cob Spotlight, ambient and accent lighting are on the same track for easy installation. And the flexibility is also very strong to move on the track. It is different from other led linear lights in that it is very invisible because it is an LED Linear Light embedded in the track. The light efficiency is 110-130lm/w, Flicker-free driver, THD<15%, the color rendering index can reach up to 97. Compared to other LED Track Lights, this Led Track Linear Light will cost less. So if you are looking for cost-effective and good quality LED Track Lights, you can choose this product.
There are 3 different types of this led track lighting:
1. PC Led Track Linear Light: Its beam angle is 120 degrees, and the diffuser is made of an imported PC that doesn't turn yellow easily.
2. Grille Linear Track Light with straight blade louver: Its beam angle is 24°, 50°, 60°, 90°, UGR<19. It can better protect human eyes.
3. PMMA Linear Track Light with Micro Prismatic Optic: UGR>19 anti-glare, the lens is very beautiful and delicate.
They can match the following brand tracks:
These lights come in 4 sizes: 2ft, 3ft, 4ft, and 5ft. There are 4 wattages: 10w, 20w, 30w, and 40w.
The main specifications are 2ft, 10w; 2ft, 20W; 3ft, 20W; 3ft, 30W; 4ft, 30W; 4ft, 40W; 5ft, 30W; 5ft, 40W.
