Hydraulic valves

Hydraulic distributor: device, principle of operation, scope of application

A hydraulic distributor is an auxiliary type device that changes the vector direction when liquid moves in a system of production units and mechanisms. The meaning of this special device is that in order to activate certain mechanisms, it is necessary to monitor the accuracy and sequence of fluid flow changes. The most common ways to connect the device are: flanged, threaded, butt. A hydraulic distributor can be used for various types of liquids, but the main use of the equipment is for the redistribution of flow, pressure parameters and the level of oil compositions.

More often, the structural device of the devices includes several elements: a housing, different types of valves, clamps and control units, distribution channels.

The principle of operation

According to the principle of operation, the electric distributor goes through the following stages:

1. The unit is switched on, after which the DC electromagnet located on the housing begins to act on the pusher and the finger.
2. The pusher then transmits the impact to the ball valve, which is pressed against the seat.
3. The hydraulic motor begins to function: it removes liquid from the working system, displacing it into the drain tank.
4. In the opposite direction, the liquid returns when electricity is not supplied to the electromagnet. As a result, the composition enters the working line of the power unit.
5. The working tank is closed using a non-return valve, as a result, the liquid does not have the ability to move in the system of production mechanisms.

Regardless of which kind of hydraulic distributor you decide to buy, any model will have the same principle of operation.

Types and classification of hydraulic valves

There are several different classifications that divide devices into types. Depending on which type of control you choose – electric, hydraulic, mechanical or manually operated, the price for the hydraulic distributor will differ significantly.

According to the number of external contours of the hydraulic lines, the devices are classified into: two and three-line, according to the number of positions of the locking device there are: two and three-position products.

The most common classification divides the equipment into three types:

• The spool is a popular variety with an elementary device, it includes a cylindrical spool configuration, the movement of which changes the flow vector of the liquid medium.
• The crane distributor of the hydraulic system – with the main element in the form of a crane plug, which is responsible for the distribution of flows by turning. An important condition is the complete tightness of the system.
• Valve – works due to the presence of a valve – a reliable element, compared with a spool, since it can function at high pressure parameters of the working fluid.

Scope of application

The fields of application are multifaceted and cover various areas of industry and the national economy, since the use of such an aggregate is considered a necessary condition in any hydraulic systems.

It is advisable to buy a hydraulic distributor for:

• Installation in machines and equipment;
• Arrangement of freight transport;
• Maintenance of special equipment used in the construction and mining industries;
• Installations in crane units, manipulators, lifting mechanisms;
• Agricultural machinery and equipment.
