Acting hydraulic valve

hydraulic valve block is a pressure oil operations automation components used, which is controlled by pressure control valve pressure oil is usually used in combination with electromagnetic pressure valve can be used for remote control station oil, gas and water pipeline system off. Commonly used in clamping, control, lubrication oil passage. There are direct acting and pilot type of points, the use of pilot type.
Acting hydraulic valve manifold are used to control the flow direction of the hydraulic system in the oil or adjusting the pressure and flow, so it can be divided into directional valve, pressure valve and flow valve three categories. A shape of the same valve, can be because of the different mechanisms of action, and have different functions. Pressure valve and flow valve with a through-flow cross-section of throttling control the pressure and flow system, and directional valve replacement through the use of flow paths which control the direction of flow of oil. That is, although there are a variety of hydraulic valves of different types, among them still maintain some basic points in common.

The importance of the hydraulic valve

hydraulic valve block manifold do not flip gate (ie handwheel down), otherwise it would be retained in the valve cover long-term media space, easily corroded valve stem, and for certain process requirements are taboo. At the same time replace the packing very inconvenient.
1, the valve to be installed vertically on a horizontal pipe, do not tilt in all directions.
2, lift check valve, when the valve is installed to ensure that its vertically to lift flexible.
3, swing check valve, when installed to ensure its pin level to swing flexible.
4, stem gatehydraulic valve manifold, do not install in the ground, otherwise due to moisture and corrosion exposed stem.

About pump

Hydraulic pump means usually, hydraulic valve, fuel tank, electrical boxes and other parts combination. Wherein the pump means includes a motor and pump, it is a source of hydraulic power station, the mechanical energy is converted to pressure hydraulic oil can. Hydraulic valve manifold assembly and from the hydraulic valve, the hydraulic fluid to implement its direction, pressure and flow regulation. Steel plate welded into the tank is half-closed container, fitted with grease filter, air filter, etc., which is used to store, cooling and filtering oil. Electrichydraulic hose assemblybox is a hydraulic station power distribution systems and interface with the plant electrical control system, you can set only the external lead terminal plate can also be supporting the full range of electrical control.
Traditional hydraulic station generally use open tank, hydraulic pump can be arranged beside the tank, above and below the liquid level inside the tank, thereby forming a side mounted, the set of horizontal, vertical hydraulic station on the set. Cooling hydraulic station can be divided into natural cooling and forced cooling. Natural cooling without additional cooling equipment, relying on natural air convection and heat exchange tank. General requirements for the tank volume large enough. Forced cooling methods include air, water, refrigerant refrigeration and other forms. Generally in accordance with the work requirements of the rational use ofmetric hydraulic hose fittings hydraulic station, forced cooling can effectively control fluid temperature, and can reduce the fuel tank volume requirements.

Features hydraulic cutting machine

Features hydraulic cutting machine is: When punching through the cutter head is momentarily acting on the workpiece, the pressure within the fuel tank does not reach the rated pressure, the pressure will be in contact with the (cut work material) of the time increases, until solenoid valve receives a signal, reversing valve, cutting head starts reset; when the pressure inside the fuel tank into the cylinder due to limited time, pressure oil, may not reach the rated pressure set value; that is,He said that the system pressure does not reach the design value, hose cutting machine has been completed.

Classification of hydraulic valves

hydraulic valve blockcontrol method according to classification: manual, electric, hydraulic control
By function: flow valve (throttle control valve, bypass flow valve), the pressure valve (relief valves, pressure reducing valves, sequence valves, unloading valves), directional valve (electromagnetic valve, a manual shift to the valve, check valve, check valve)
According to the installation point: plate valve, in-line valve, the valve stack, Cartridge Valve, valve cover
By manipulation of points: manual valves, motorized valves, electric valves, hydraulic valves, electric hydraulic valve manifold.

hydraulic machines Works

hydraulic machines Works
(1) hydraulic system compact, easy to install, assemble short cycle.
(2) If the hydraulic system has changed, when changing conditions require changes in components, High Pressure Block easily and quickly assembled.
(3) realize the connection between the elements ductless eliminate leakage due to tubing, reusable hydraulic hose fittings pipe joints caused by vibration and noise.
(4) the entire system configuration flexibility, neat appearance, easy maintenance.
(5) standardized, universal and high degree of integration.
