Because the za comprised exist at the same time and make the pressure maintaining pressure too fast, after initiation impact vibration and noise, we of the hydraulic circuit is improved. When the stem K have stem pressure oil, the oil due to stem the piston push rod, the ejector push open the unloading valve core, the main valve core to open at the same time, through to two his P1, P2, free flow of oil can be in this two party aspirant, unloading valve reduces the hydraulic impact, make the performance of the hydraulic control one-way valve is safe, but there are still in the large flow rate high pressure system impact or noise. Once the Ann circuit implemented with high pressure, high flow hydraulic controlled check valve as improvements, the final results can be satisfied with the requirement, do not affect restrict the speed of the piston. Q: hydraulic controlled check valve and throttle valve and it should use a: hydraulic controlled check valve in the hydraulic circuit application is very extensive, but in the application of this valve, Marine valve should be fully test about the valve's unique place, otherwise it will cause the loop variable, especially in a high pressure system, hydraulic control one-way Industrial Valves reverse pressure P2 before opening the mouth, as shown in figure 1 a, in order to reduce the pressure of hydraulic system of the stem, hydraulic shock and noise, think appropriate and use the unloading valve core hydraulic control one-way valve, as shown in figure 1 b. As shown in figure 2 a shows the holding circuit, because the system mediator in the process of pressure due to high pressure, the oil compression, expansion pipe, components such as elastic variant can be stored the + 羭, at the time of pressure relief, kidney volume suddenly released, and in the reversing valve, from one place to the left because of cavity pressure on the hydraulic cylinder, the cavity pressure has been rising at present, as shown in figure 1 b method of unloading valve and main valve open almost at the same time, make the oil cavity pressure on suddenly after hydraulic controlled check Industrial Valves free to back to the oil. Because of the high pressure large flow hydraulic controlled check valve caused the pressure too fast, make impact increases, therefore in the loop with a throttle valve ( As shown in figure 2 b) , thus make the hydraulic controlled check valve unloading valve open first, then open the main valve, stem due to throttle valve have sufficient flow range, can guarantee the safe minimum flow, convenient adjustment, small leakage, temperature and pressure influence is small, so after the piecewise flow valve, stem oil pressure on the hydraulic cylinder cavity time also extended accordingly, transfer pressure experienced will also strengthen, get back on the hydraulic shock and noise of each element. Commonly used in hydraulic control one-way valve pressure, pressure relief, lock loop. 。 Unloading valve can get improved, improves the performance of the hydraulic controlled check valve of the hydraulic controlled check valve is a unique place, when the hydraulic controlled check valve K are in a no pressure oil, oil pressure oil can only flow from oil P1 mouth to mouth (P2), not the reverse. 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. Second, if the valve has been selected by design unit of our company model, please order according to the valves parameters directly with our sales center.
