Cone valve is a suitable for high head, large flow conditions, no vibration, no cavitation operation, continuous discharge flow control of new valve products. Due to the use of inverted conical plunger spool named, referred to as the cone valve. Because of its excellent energy dissipation effect, it is also called energy dissipation valve. Cone valve in addition to the end of the channel is provided with a conical valve core, all the moving parts are set in the valve flow channel outside, so that the valve body internal flow is usually smooth, large flow and pressure drop loss is small, the entire working range will not produce cavitation and vibration, and in the small flow still has good flow control effect. The conical valve developed by our company has a fixed inverted conical structure. It is supported by hydraulic design and four guide wing blades used to reduce vibration. The flow rate is controlled by the front and back movement of the external movable casing. The valve body is respectively provided with metal-to-metal valve seats and supplementary soft sealing valve seats, which constitute a composite valve seat to ensure sealing performance. When discharged into the atmosphere, the water flow spreads at a wide cone angle and breaks down into a thin spray pattern, expending energy in the air. Usually according to the actual needs, can be required to control the water flow area, then install a different form of deflector at the outlet, which can not only mix the air with sufficient water, but also concentrate the flow. The results of the cone valve test showed no significant vibration, and the discharge coefficient was around 0.9 with or without the shroud when the fixed cone was fully open. ZF cone valve is mainly used in hydropower stations, reservoirs and urban water supply and drainage areas.

Product overview: This product is used for the highest point on the sewage pipe or a place with closed air to exclude the gas in the sewage pipe to dredge the pipe. Make the pipeline run normally, if not installed this valve, the pipeline will appear closed air, so that the flow rate of sewage by air resistance, and even interrupted. Working principle: when the sewage in the pipe moves, the valve flap stops at the lower part of the fixed door frame. When the air is exhausted, the sewage enters the valve to float the ball first and pass it to the valve until it is closed. The naturally occurring gas inside the tube will be concentrated to the upper part of the tube to a considerable extent, and the valve hole will be discharged.

CARx Composite Exhaust Valve The valve body is barrel-shaped, and the internal parts of the valve include stainless steel float ball, lever and disc. The valve is installed at the outlet of the pump or in the water distribution pipeline to exclude the air in the pipe to improve the efficiency of the pipeline and the water pump. When negative pressure is generated inside the tube-once. This valve quickly sucks in outside air to prevent damage to the pipeline due to negative pressure. Composite exhaust valve for the highest point on the pipeline or a closed place, the gas in the tube to clear the pipeline, to achieve normal work. If the exhaust valve is not installed, the liquid flowing in the pipe will generate dynamic heat and cause gas to form a short circuit, which will make the water outlet capacity of the pipe fail to meet the requirements. Secondly, the pipe will have negative pressure when the pipe is running and the pump will stop, which will cause the pipe to vibrate or rupture. The exhaust (suction) valve quickly sucks air into the pipe to prevent pipe vibration or rupture. Its working principle is: When the water injection in the pipe starts, the valve flap is in the open position to perform a large amount of exhaust. When the air is exhausted, the valve is filled with water, the float rises and drives the valve flap to close, and the exhaust is stopped. When the water in the pipe is transported normally. If a small amount of air collects in the valve to a considerable extent, the water level in the valve drops, and the air is discharged from the small hole. When the water pump stops, the water in the pipe is empty or negative pressure is generated in the pipe. At this time, the plug head is quickly opened to inhale air to ensure the safety of the pipeline. Medium temperature: 0-80 ℃.

The adjustable pressure relief valve is a special valve installed on the water supply and drainage system pipeline of high-rise buildings to reduce the inlet pressure to a certain outlet pressure. The valve relies on its own energy to keep the outlet pressure stable at the set value, that is, the outlet pressure does not change due to the change of inlet pressure and flow rate. A self-cleaning filter screen is installed at the inlet of the valve control system to make the specific gravity larger by using fluid characteristics, larger diameter suspended particles will not enter the control system, to ensure that the system circulation unimpeded, so that the valve can operate safely and reliably. The system is sensitive and has a long service life.

Installed in high-rise buildings, fire water supply systems and other water supply systems on the pipeline, when the pressure in the water supply pipeline exceeds the set pressure of the pressure relief valve, the pressure relief valve automatically opens for rapid pressure relief to protect the safety of the pipeline, and can also be used as a holding valve to ensure the water supply pressure upstream of the main valve. Can accurately maintain the same security set pressure, one and overpressure, pressure relief valve quickly open, timely pressure relief. Close smooth and reliable, eliminate the pressure after-wave.

200X pressure reducing valve is an intelligent valve that uses the energy of the medium itself to adjust and control the pipeline pressure. 200X pressure reducing valve is used for domestic water supply, fire water supply and other industrial water supply systems. By adjusting the decompression pilot valve, the outlet pressure of the main valve can be adjusted. The outlet pressure does not change due to changes in inlet pressure and inlet flow. The outlet pressure is safely and reliably maintained at the set value, and the set value can be adjusted as needed to achieve the purpose of decompression. The valve has accurate decompression, stable performance, safety and reliability, convenient installation and adjustment, and long service life.

500X pressure relief/holding valve is composed of main valve, pilot valve, needle valve, ball valve, micro filter and pressure gauge, hydraulic control pipe system. The use of hydraulic automatic operation, that can be used as a pressure relief valve can also be used as a holding valve. When the pressure relief valve is used, it can maintain the pressure of the water supply circuit below the set safety value and maintain the upstream water supply pressure of the main valve o. Its working principle, when the pilot valve is adjusted to the pressure relief state, the water flows to the outlet through the needle valve, the main valve control room, ball valve A, pilot valve and ball valve B, and the main valve is open at this time. When the inlet pressure exceeds the safety value set by the pilot valve, the pressure relief pilot valve will automatically open, and part of the water will be released through the ball valve c to relieve the pressure of the pipeline.
