Abstract

The utility model provides an improved oil circuit block. Oil passing grooves are arranged on the two sides of the oil circuit block, and the oil passing grooves on one side of the oil circuit block are vertical to the oil passing grooves on the other side of the oil circuit block, the oil passing grooves at the same side of the oil circuit block are parallel to each other, and screw threads are arranged at the front ends of the oil passing grooves. The improved oil circuit block has the beneficial effects that: as the design of the oil passing grooves on the oil circuit block is changed, an oil pipe can be connected with the oil circuit block without being bent; oil leakage is prevented, and pressure loss caused by bending the oil pipe is avoided; and the improved oil circuit block has the advantages of simple structure, convenience for maintenance, low processing cost, high production efficiency and the like.

Description

A kind of improved manifold block

Technical field

The utility model relates to a kind of oil connection device, especially relates to a kind of anti-leakage of oil, the improved manifold block that the hydraulic fluid pressure loss is little.

Background technique

Like Fig. 1, the hydraulic station outside is provided with baffle plate, and most hydraulic stations were realized with being connected through the transition tube pipeline connector of external device in existing technology.Under this Placement, the operation of screwing of a plurality of transition tube pipeline connectors makes baffle plate generation deformation.Because baffle plate is the piece thin plate, after the generation deformation.The transition tube pipeline connector produces the leakage of oil point with crossing being threaded between the oil groove, causes the hydraulic system leakage of oil.

Like Fig. 2, also exist the manifold block that utilizes straight shape to cross oil groove to connect the situation of hydraulic station and external device.Though this linkage structure has solved the problem of hydraulic system leakage of oil, there is bending in oil pipe, causes hydraulic oil to have the pressure loss, and making oily temperature rise directly influences the work of hydraulic system.The harm of oil temperature rise:

The warm too high meeting of oil causes the hydraulic pressure oil viscosity to descend, and is easy to generate leakage, and volumetric efficiency is reduced;

The part of hydraulic system expands because of overheated; Owing to the linear expansion coefficient of each constituent element of system, be heated and radiating condition is not quite similar; Each several part expanded by heating situation is also not exclusively the same, thereby the distortion that produces is also different, may destroy the original normal matching gap of part of relative movement; Cause surface friction drag to increase, it is stuck that spool is prone to;

Also possibly destroy the oxidation stability and the thermostability of fluid;

Quicken the Sealing aged deterioration, the lost of life, the loss of seal performance is seriously leaked system; The oil temperature is too high, is easy to generate impurity etc.

Summary of the invention

The problem that the utility model will solve provides a kind of improved manifold block, effectively connects hydraulic station and external device; Characteristics with anti-leakage of oil, and the design that changes manifold block makes and do not need bending oil pipe again, avoided the pressure loss.

For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of improved manifold block, manifold block are provided with the rectangular each other oil groove of crossing, and cross the oil groove front end and have screw thread.

Further, crossing oil groove is parallel to each other.

Further again, also have screw on the manifold block.

Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, changed the design of oil groove excessively in the manifold block, oil pipe need not bending again and just can be connected with the mistake oil clot; Neither can produce the situation of leakage of oil, avoid again because the pressure loss that the oil pipe bending causes; Have simple in structurely, easy to maintenance, processing cost is low, the manufacturing efficiency advantages of higher.

Embodiment

As shown in Figure 3, the utility model provides a kind of improved manifold block, and manifold block 1 is provided with rectangular each other oil groove 2 excessively, crosses oil groove 2 front ends and has screw thread.

Crossing oil groove 2 is parallel to each other.

Also have screw 3 on the manifold block 1.

The working procedure of this instance: like Fig. 3; Perforate on baffle plate 5; Manifold block 1 is passed baffle plate be installed on the hydraulic system, the fluid in the hydraulic station passes through oil pipe 4, crosses oil groove 2 to external world's supply, has avoided being out of shape owing to baffle plate 5 phenomenon of the hydraulic system leakage of oil that causes.Cross the right angle type design of oil groove 2, make that oil pipe 4 need not can directly to be connected with manifold block 1 through bending operation again.

More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
