In recent years, from the tightly closed valve after the show, the Industrial Valves is replaced by the disc above the medium flow direction into the valve cavity, then under medium pressure utility, close the valve of the force is small, and the strength of the valve, the valve stem diameter can detract from accordingly. 。 At the same time, under the media effect, this type of valve is also relatively narrow clerestory. So by the end of valve position of the whole paper, should by the disc stroke to vote. When the media by the disc into the below 6, operating force needed to overcome resistance, is stem and packing friction with the initiation of thrust by medium pressure, close the valve force stronger than open the valve, so it's bigger, the diameter of the stem or stem top bending failure happens. By the end of the valve opens, the opening of the disc height, one hundred percent to one hundred percent of nominal diameter 25 ~ 30, traffic has reached maximum, to express the valve has reached the whole paper. 3, tightly closed, tightly closed between friction force is small, the survival of the fixed number of year is longer than the other. Speckle tube by the valve has the following advantages: 1, simple structure, production and maintenance more convenient. 2, uncomfortable to use in large Marine valve with particles, viscosity, easy to medium of coke. in China 'three for' had rules, by the end of valve flow, one sees fit and use from top to bottom. By the valve ownership forced tightly closed valve, the valve is closed, it is important to increase on the disc pressure force, to force the tightly closed surface is not leaking. Stem has up and down movement way, the lever ( The valve stem up and down, the handwheel is not up and down) , there are up and down rotating lever ( The handwheel with spin up and down together, the stem nut is located in the body) 。 The valve is only suitable for use in the whole paper and seated, to adjust and throttling is not allowed. 2, small office tour, opening and closing time is short. The lack of the valve as follows: 1, the fluid resistance is big, open and close the required force is larger. 3, poor regulation performance. Based knowledge a: q: striped tube by the valve opening and closing of the valve is the plug valve, tightly closed like the simplest surface or cone, the disc along the fluid core line of linear motion. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
