Abstract
The utility model discloses a tee bend switching -over overflow valve, including casing, switching -over seat, pivot and handle, be provided with into oil pipe, play oil pipe, overflow pipe and base on the casing, it sets up on the base respectively to advance oil pipe, play oil pipe and overflow pipe, the handle passes through the pivot with the switching -over seat is connected, be provided with a plurality of through -holes on the switching -over seat, the lower extreme of pivot be provided with with through -hole complex link hole, advance oil pipe, go out and be provided with between oil pipe and the overflow pipe the switching -over seat, it is a plurality of the through -hole corresponds respectively advance oil pipe, go out oil pipe and overflow pipe. The utility model discloses a manual switching -over seat of setting in the oil circuit can be with the unnecessary flow low pressure off -load of one or more constant delivery pump when the system requirements low discharge to reach energy -conserving purpose, simple structure, convenient to use.
Description
Technical field
This utility model relates to a kind of overflow valve, refers more particularly to a kind of triplet commutation overflow valve.
Background technology
Fixed dilivery hydraulic system Application comparison in engineering machinery is extensive, requirement due to machine operating mode, when machine is in action at a slow speed or during relatively large load less to the traffic demand of hydraulic system, but quantitative system provides constant flow, therefore generation is had more than needed by the flow in system, the most just require by overflow valve or constant difference overflow valve, flow unnecessary for the one or more dosing pumps in system will be overflowed back fuel tank, but the most still can cause the bigger pressure loss, therefore, just requiring can be by flow Low-pressure load discharge unnecessary for one or more dosing pumps when system requirements low discharge, thus reach certain energy-saving effect.
Utility model content
The purpose of this utility model is that provides a kind of simple in construction, practical and convenient triplet commutation overflow valve to solve the problems referred to above.
This utility model is achieved through the following technical solutions above-mentioned purpose:
This utility model includes housing, inverting seat, rotating shaft and handle, oil inlet pipe, flowline, overflow pipe and base it is provided with on described housing, described oil inlet pipe, flowline and overflow pipe are separately positioned on base, described handle is connected with described inverting seat by described rotating shaft, multiple through hole it is provided with on described inverting seat, the lower end of described rotating shaft is provided with the linked hole coordinated with described through hole, described inverting seat it is provided with, multiple described through holes corresponding described oil inlet pipe, flowline and overflow pipe respectively between described oil inlet pipe, flowline and overflow pipe.
Further, described inverting seat and described inner walls are provided with positioner, and described positioner includes positioning spring and steel ball, and described steel ball is connected with described location spring, described inner walls is provided with the locating slot coordinated with described steel ball, and described locating slot is arranged on the top of oil pipe.
Further, multiple described through holes are three, and the aperture ratio of three described through holes is 1:2:3, three described through hole 120 ° of parallel distributions each other.
Further, described housing and described base are bolted.
Specifically, it is provided with sealing ring between described inverting seat and described housing.
The beneficial effects of the utility model are:
This utility model by flow Low-pressure load discharge unnecessary for one or more dosing pumps, thus can reach energy-conservation purpose when system requirements low discharge by the manual reverse of direction seat being arranged in oil circuit, and simple in construction is easy to use.

Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings:
Such as Fig. 1, shown in 2 and 3, this utility model includes housing 1, inverting seat 8, rotating shaft 2 and handle 3, oil inlet pipe 6 it is provided with on housing 1, flowline 7, overflow pipe 5 and base 9, oil inlet pipe 6, flowline 7 and overflow pipe 5 are separately positioned on base 9, handle 3 is connected with inverting seat 8 by rotating shaft 2, multiple through hole 81 it is provided with on inverting seat 8, the lower end of rotating shaft 2 is provided with the linked hole 82 coordinated with through hole 81, linked hole 82 is unidirectional linked hole, when turning handle 3 time, the liquid of oil pipe can only switch into flowline 7 or overflow pipe 5, oil inlet pipe 6, inverting seat 8 it is provided with between flowline 7 and overflow pipe 5, the most corresponding oil inlet pipe 6 of multiple through holes 81, flowline 7 and overflow pipe 9.
Inverting seat 8 and housing 1 inwall are provided with positioner, and positioner includes positioning spring 83 and steel ball 84, and steel ball 83 is connected with location spring 84, and housing 1 inwall is provided with the locating slot coordinated with steel ball 83, and locating slot is arranged on the top of oil pipe.
Multiple through holes 81 are three, and the aperture ratio of three through holes 81 is 1:2:3, three through hole 120 ° of parallel distributions each other, by selecting the through hole 81 of different pore size ratio to meet the demand to oil circuit flow.
Housing and base are bolted, and are provided with sealing ring between inverting seat and housing, reduce oil circuit and reveal.
This utility model by flow Low-pressure load discharge unnecessary for one or more dosing pumps, thus can reach energy-conservation purpose when system requirements low discharge by the manual reverse of direction seat being arranged in oil circuit, and simple in construction is easy to use.
These are only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, should be included in protection domain of the present utility model.
