Abstract
The utility model provides a kind of isolating valve of hydraulic system accumulator, including：Valve rod, spool, sealing element, nut, it is characterised in that：The valve rod is cylinder, is placed in the valve body of cylindrical type；The nut is mounted at the half outside valve body；The sealing element is mounted on the lower section of nut for sealing ring；The spool is arranged on the bottom of valve body, is provided with hydraulic pressure oil hole.On a control block, control block surface and inside process hole and oil circuit with different function, are connected with the oil inlet pipe and flowline of accumulator for isolating valve inserting provided by the utility model.The one open-one close of isolating valve just completes the switching of control block internal oil passages, realizes putting into operation and being isolated for accumulator.Ensure online be isolated when accumulator breaks down, do not need to shutdown processing.
Description
Technical field
The utility model is related to hydraulic system technical field, more particularly to a kind of isolating valve of hydraulic system accumulator.
Background technology
Accumulator is one of equipment of hydraulic system indispensability, plays absorption system pressure fluctuation and stocking system hydraulic energy
Important function, working performance directly affect the reliability of hydraulic system.Accumulator usually connect with the connection of system and
Two ways is bypassed, part accumulator is mounted in bypass, installs accumulator can be realized in cut-off gate isolation and online processing additional
Defect, but for the accumulator for being serially connected in system, part is not filled isolating door or cannot be met using simple shut-off valve
It is required that the failure that processing accumulator occurs can only be shut down.
Invention content
The utility model provides a kind of isolating valve, can be cut for the control block internal oil passages of installation accumulator by valve realization
Conducting is changed, by isolating valve inserting to the side of control block, spool cooperates with oil circuit completes oil circuit conversion.
To achieve these goals, the utility model provides following technical scheme：A kind of isolation of hydraulic system accumulator
Valve, including：Valve rod, spool, sealing element, nut, the valve rod are cylinder, are placed in the valve body of cylindrical type；Described
Nut is mounted at the half outside valve body；The sealing element is mounted on the lower section of nut for sealing ring；The spool
The bottom of valve body is arranged on, is provided with hydraulic pressure oil hole.
Preferably, accumulator is mounted in pre-designed control block, control block is processed with different function
Oil circuit, the connection with accumulator, system oil-way and isolating valve.The effect of isolating valve realizes that spool is unique by spool completely
Structure can realize the switching of control block internal oil passages, and then accumulator is isolated.
By implementing above technical scheme, there is following technique effect：It disclosure satisfy that the accumulation of energy being serially connected in system oil-way
When device breaks down, by the closing of isolating valve, it can realize and flow through the medium of control block around accumulator, complete cycle or reach
To specific purposes.
Description of the drawings
Fig. 1 is the isolating valve structure diagram of the utility model.
Fig. 2 is hydraulic system accumulator provided by the utility model and isolation valve assembly figure.

Pipe, 108, isolating valve, 109, control block.
Specific embodiment
In order to be better understood from the technical solution of the utility model, the utility model is described in detail below in conjunction with the accompanying drawings and provides
Case study on implementation.
The utility model embodiment provides a kind of isolating valve of hydraulic system accumulator, including：Valve rod, spool, sealing element,
Nut, the valve rod are cylinder, are placed in the valve body of cylindrical type；The nut is mounted on the half outside valve body
Place；The sealing element is mounted on the lower section of nut for sealing ring；The spool is arranged on the bottom of valve body, is provided with
Hydraulic pressure oil hole.
In the above-described embodiments, more specifically, as shown in Fig. 2, control block is by processing the internal oil circuit for forming perforation,
Accumulator then stands upside down installation on a control block, and isolating valve inserts on a control block, and accumulator is realized using the switch of isolating valve
Isolation.System coming oil arrives flowline again through oil inlet pipe to accumulator when isolating valve is opened, and accumulator comes into operation.Isolating valve closes
System coming oil arrives flowline again through oil inlet pipe around accumulator when closing, and accumulator is isolated at this time, with ensure accumulator online every
From being safeguarded.
In isolating valve installation control block, ensure that valve is in closed state, accumulator not yet fills, and the oil outlet of control block is sealed
It closes, the compressed air of certain pressure is passed through at oil inlet, check at accumulator without gas overflowing, secondly connect accumulator
It is closed at mouthful, checks that oil outlet has gas overflowing, show that isolating valve can realize the online isolation features of accumulator.
The isolating valve of a kind of hydraulic system accumulator provided above the utility model embodiment has carried out detailed Jie
It continues, for those of ordinary skill in the art, based on the idea of the embodiment of the present invention, in specific embodiment and using model
There will be changes are placed, in conclusion the content of the present specification should not be construed as a limitation of the present invention.
