Embodiment Construction

[0018] This embodiment proposes a light-weight composite general-purpose valve group of a large-scale anchor winch pump station, and its structure is shown in the figure.

[0019] Combining and optimizing the previous multiple valves into a valve group, so that the product is lighter than before, smaller in size, easier to install, and reduces vibration and noise problems during startup. By adopting a special valve block hole design, Different combinations of plug-in overflow valve, plug-in two-position three-way electromagnetic reversing valve, plug-in check valve, damping plug and plug are used to meet the requirements of double-pump isolation, safety protection, Unloading start and double pump synchronous control and other functions. The versatility of this valve group is reflected in the fact that it can control pump groups with different control functions. 2. The main overflow valve 4 is installed behind the one-way valve 3, so that double pumps or multi-pumps can share ...

Abstract

The invention discloses a large anchor and mooring machine pump station lightweight composite general valve group, which comprises two groups of control oil ways arranged in parallel, and each control oil way is composed of a general valve block, a first one-way valve, a first overflow valve, an electromagnetic directional valve, a second overflow valve and a second one-way valve which are connected in sequence; the electromagnetic directional valve is a two-position three-way electromagnetic valve and is inserted into the general valve block through threads, and the first one-way valve, the second one-way valve, the first overflow valve and the second overflow valve are connected with the general valve block through pipe joints and threads. The universality and interchangeability are greatly enhanced, meanwhile, the weight and the size of the product are reduced by about one third through the modularized and integrated optimization design, the light weight effect is achieved, and installation and use are more convenient. Due to the fact that the pipe hole of the valve block is optimized, noise and vibration are reduced.

Description

technical field [0001] The invention relates to a composite general valve group, in particular to a lightweight composite general valve group for a pumping station of a large windlass windlass, belonging to the technical field of ship brake control. Background technique [0002] With the continuous and rapid development of the shipbuilding industry, the market has higher and higher requirements for hydraulic systems, and the requirements for marine products are developing towards generalization, modularization, light weight, miniaturization, energy saving and noise reduction. There will be two or more pump sets in the hydraulic system of the anchor winch equipment, usually two sets. Hydraulic system through hydraulic pump [0003] Discharge high-pressure oil to drive the actuator to work, and set a safety valve so that when the pressure in the hydraulic system pipeline exceeds the set working pressure, the hydraulic oil is discharged into the oil tank to prevent the pipelin...
