Description

Hydraulic control one-way valve mounting seat

Technical Field

The utility model relates to a hydraulically controlled check valve correlation field specifically is a hydraulically controlled check valve mount pad.

Background

The pilot operated check valve is a valve which can make the check valve reversely flow by controlling the pressure of fluid. The valve plays a more important role in the hydraulic support equipment of the coal mine machinery. The hydraulic control one-way valve is different from a common one-way valve in that a control oil way is added, when the control oil way is not communicated with pressure oil, the hydraulic control one-way valve works like the common one-way valve, and the pressure oil only flows to an oil outlet from an oil inlet and cannot reversely flow. When control pressure is input into the control oil path, the piston mandril moves rightwards under the action of pressure oil, and the one-way valve is jacked open by the mandril, so that the oil inlet and the oil outlet are communicated. If the oil outlet is larger than the oil inlet, the oil can flow reversely. On-site practice proves that the hydraulic control one-way valve is easy to have problems in the use and maintenance process, and the following matters are taken as notice: it must be ensured that the pilot operated check valve has sufficient pilot pressure and absolutely no loss of pilot pressure is allowed. Care should be taken whether the control pressure meets the requirement for reverse opening. If the control of the hydraulic control one-way valve is led from the main system, the influence of the pressure change of the main system on the pressure of the control oil way is analyzed so as to avoid the misoperation of the hydraulic control one-way valve; according to the position of the hydraulic control one-way valve in the hydraulic system or the flow resistance after the hydraulic control one-way valve reversely flows out of the oil cavity.

The existing hydraulic control one-way valve mounting seat is complex in structure, needs more parts during mounting, is low in efficiency during actual assembly, and is not fast and convenient enough; therefore, the market urgently needs to develop a hydraulic control one-way valve mounting seat to help people solve the existing problems.
