On the one hand for independently installed explosion-proof valve, restriction effect has further been reached, and make in pipe breakage, oil
Cylinder is unaffected, and further extends the service life of oil cylinder.On the other hand, in the installation and removal process of explosion-proof valve
In, system pressure is effectively guaranteed, greatly facilitates the workflow and safe and convenient of staff.Reach fine
Save the cost effect.
(5) a kind of explosion-proof valve module of Combined oil cylinder of the present invention, is mounted with overflow valve, on the one hand plays good system
Pressure maintaining effect；On the other hand, when the system pressure for flowing through valve group is excessive, overflow valve is jacked up, and a part of oil liquid flows through overflow
Valve plays the role of quick pressure releasing, ensure that the stabilization and balance of system pressure.When system breaks down, due to input
Hydraulic fluid port is plugged, and in oil cylinder maintenance, from when spare hydraulic fluid port oil inlet, flows through oil liquid, convenient oil cylinder maintenance by check valve；Normally
Under state, check valve oil circuit is open circuit.Meanwhile in failure since some explosion-proof valve action oil cylinder disconnects oil circuit,
Ball valve is opened, and opens oil circuit, oil liquid is made to circulate, and is used in maintenance, ball valve is in off state under normal circumstances, plays dual guarantor
Shield.
Detailed description of the invention
Fig. 1 the structural representation of present invention.
Specific embodiment
The implementation of technical solution is described in further detail with reference to the accompanying drawing.Following embodiment is only used for more clear
Illustrate to Chu technical solution of the present invention, and not intended to limit the protection scope of the present invention.
As shown in Figure 1, a kind of explosion-proof valve module of Combined oil cylinder, including oil cylinder 1, the first explosion-proof valve 21, the second explosion-proof valve
22, the first board-like ball valve 31, the second board-like ball valve 32, the first pressure measuring tie-in 41, the second pressure measuring tie-in 42, first pressure gauge 51,
Second pressure gauge 52, first pressure gauge switch 61, second pressure gauge switch 62, the first overflow valve 71, the second overflow valve 72, first
Ball valve 81, the second ball valve 82, the first check valve 91 and second one-way valve 92；
When rodless cavity oil inlet, oil liquid is flowed into through A mouthfuls of input oil port, flows through the first explosion-proof valve, board-like ball valve enters rodless cavity, effect
In oil cylinder, at the same time, the first pressure measuring tie-in in oil liquid valve block, first pressure gauge and first pressure gauge switch are opened, display
Oil circuit pressure changing value at this time monitors oil circuit pressure；Meanwhile when rod chamber oil inlet, oil liquid flows through B mouthfuls of input oil port inflows,
Principle is same.
Oil cylinder normal work in, if a certain instantaneous pressure table monitoring flow through system certain lateral pressure it is relatively high when,
Oil liquid can open overflow valve in outflow, so that part oil liquid goes out to flow out from overflow valve, play the role of quick pressure releasing, ensure that
Oil pressure in system protects cylinder pipe in the range of a normal table, extends cylinder pipe service life.
When oil cylinder breaks down, and external oil pipe ruptures, oil inlet and outlet is resulted in oil cylinder since explosion-proof valve acts at this time
Block, in order to which oil cylinder is using safe, at this point, in order to overhaul oil circuit other parts it is whether impaired when, from spare hydraulic fluid port T mouthfuls into
Oil flows through inside check valve oil cylinder, overhauls other oil circuit safe conditions.If other oil circuits are safe, new explosion-proof valve is installed at this time
Later, it can continue to use, such scheme plays maintenance effect well for the oil circuit inside valve block, and conveniently has
Effect, has saved cost.Meanwhile under normal circumstances, if under needing the situation of periodic maintenance inspection in operating condition, such scheme
It is same effectively convenient.
If a certain explosion-proof valve action oil cylinder therein or when failure block oil circuit under working condition, ball can be opened at this time
Valve flows back to oil cylinder as the circuit of oil liquid.This scheme is also suitable for using under the maintenance operating condition of oil cylinder.
Explosion-proof valve module of the invention, acts on oil cylinder, on the one hand ensures the operation of oil cylinder safety and steady, has ensured the person
On the other hand the safety of property effectively extends the service life of oil cylinder and hydraulic fluid port pipeline, has greatly saved manpower and material resources, save
Cost.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and deformations can also be made, these improvement and deformations
Also it should be regarded as protection scope of the present invention.
