The internal structure of combined valve

     Chinabase Machinery is a group of manufacturing facilities, offering one-stop solution for mechanical power transmission products in China. We can supply a full-range of power transmission products, such as chains, sprockets and plate wheels, pulleys, gearboxes, motors, couplings, gears and racks. Our product range also covers locking assemblies (clamping elements/locking device), taper bushes, QD bushes, bolt-on hubs, torque limiters, shaft collars, motor bases and motor slides, chain detachers, chain guides, universal joint, rod ends and yokes. 

    China couplings manufacturer & exporter, we specialize in: chain couplings, Jaw couplings, flexible couplings, HRC couplings, NM couplings, MH couplings, Pin coupling, Spacer Coupling, Flange Coupling, Sleeve Coupling, nylon sleeve coupling.

    Principle of automatic control 

   1 Combined type pressure reducing valve:

Combined type pressure reducing valve is a valve regulator valveself regulating by pressure or in complex condition, maintain time toproduce variations in the inlet pressure and flow pressure and flowstability. The full realization of self control, debugging is simple,reliable operation.

   2 Double feedback switch principle, combined type pressure reducing valve：

Feedback system of combined valve is the valve outlet pressurechanges according to the signal to control the flow area (throttlecone opening) independent system. The pressure relief valve is equipped with a mutual system with dual feedback spare, enable the A system operation mode disables the B system can achievethe purpose of reducing valve less downtime.

   3 The combined valve recoil sewage works:

   Operating hydropower station is complex, especially the quality is directly related to the safe operation of equipment. The higher water content of the hydropower station, in addition to the valve flowposition of stainless steel and welding nickel base alloy abrasion proof, recoil sewage device valve can effectively preventcongestion feedback control system, so that the pressure relief valve to maintain good working condition in water sediment debris.

   4 The combined valve outlet pressure locking principle:

    Each qualified decompression valve were subjected to 1.5 times thepressure more than 60 minutes, stop valve defects, even through the continuous operation of more than ten years does not appearWater Leakage fault rupture. The outlet pressure within the locking device to prevent feedback system from accidental damage, in the main under the piston pressure loss, outlet pressure to maintain theP2 value of rigid safety protection device.
