| The check valve is one kind of dependence medium this from but the flowing the
automatic start, shuts the valve petal to use for to prevent the
medium counter the automatic valve. First, the company promotes the following three kind of structure type check valve 1st, turns on lathe opens the type check valve The main model has H44F46 and the H74F46 single-lobe turns on lathe opens the type series and the H76F46 double petal turns on lathe opens the type series, their valve petal is revolves outside the place (to sell) the rotation of axis to open, to shut, prevents the medium to flow backwards. H44F46 and the H74F46 check valve's characteristic is: (sells) the axis and the valve petal design is a body, sets off FEP (to sell) the axis crustification completely in the special scoop channel which between the valve chest and the valve cover forms, opens shuts nimbly, the seal is reliable, moreover, H72F46 and H76F46 make check valve's characteristic are: Besides the valve chest, the valve petal, the recoil check spring complete packing anti-corrosive fluorine plastic, the rational design the spring, has also enabled the valve petal also to have the enough seal in the low pressure region to compare the pressure, the guarantee seal reliability. 2nd, fluctuation vertical check valve The main model has H40F46, H42F46 and H72F46 rise and fall the vertical check valve, H40F46 is one kind of new structure, the valve petal is a spheroidal, their common characteristic is the lining fluorine valve petal makes the vibratory movement along the valve chest circuit spool thread. 3rd, elevating check valve The main model has H41F46 to go nonstop to the elevating check valve, its unique feature is the lining fluorine valve petal is vertical to the valve chest import and export spool thread, no matter what vibratory movement. Second, design standard Follows GB/T the 13932, GB12235, GB12236, API6D standard. | H76F446 The double petal opens the type check valve H41F446 Elevating check valve H42 (H40) F446 Rises and falls the vertical check valve |
