Description
Technical field
This utility model relates to a kind of hydraulic test, particularly relates to a kind of plugging pin oil cylinder valve block assembly。
Background technology
In impeller dynamic test, one of them important test event is to be placed into flow deflector in ultra-large type water tank to test。This superhuge water tank, wide 3 meters, long 6 meters, weigh 132 tons when storing full water。In test process, water tank may require that in the flat surface from surface uplift to 3.2m and falls after rise to ground from flat surface, and by water tank big and heavy for this span from surface uplift to plane on be very difficult thing, especially, after water tank is lifted to flat surface, how to be fixed in flat surface by such for such as water tank super large jumbo to be extremely difficult thing。
For this, applicant expects installing plugging pin oil cylinder in the corner, bottom of water tank, rise or in descent at water tank, plugging pin oil cylinder is retracted, after water tank is lifted to flat surface position, plugging pin oil cylinder is stretched out, enables the external part of plugging pin oil cylinder to be seated in flat surface so that water tank is fixing in flat surface。
For making plugging pin oil cylinder can carry out conversion of stretching out or retract, it is necessary to require that the valve block being connected with plugging pin oil cylinder has oil transportation direction handoff functionality, and for security consideration, in addition it is also necessary to plugging pin oil cylinder can be carried out self-locking。And existing valve block assembly does not also have such function。
Utility model content
Technical problem to be solved in the utility model is to provide a kind of plugging pin oil cylinder valve block assembly, and this valve block assembly can either conveniently carry out the switching in oil transportation direction, can realize the self-locking to plugging pin oil cylinder, with the deficiency overcoming prior art to exist。
For solving above-mentioned technical problem, this utility model adopts the following technical scheme that:
A kind of plugging pin oil cylinder valve block assembly, it is characterised in that: include valve block, be located at the check valve in valve block, solenoid directional control valve, hydraulic lock, the first unidirectional adjustable throttling, the second unidirectional adjustable throttling；
Described valve block has oil-feed P mouth, fuel-displaced A mouth, fuel-displaced B mouth and oil return T mouth；
Described oil-feed P mouth is communicated to the first hydraulic fluid port of described solenoid directional control valve through check valve, second hydraulic fluid port of described solenoid directional control valve is communicated to described fuel-displaced A mouth through one of them check valve of described hydraulic lock, described first unidirectional adjustable throttling, and the 3rd hydraulic fluid port of described solenoid directional control valve is communicated to described fuel-displaced B mouth through another check valve of described hydraulic lock, described second unidirectional adjustable throttling；4th hydraulic fluid port of described solenoid directional control valve connects described oil return T mouth。
In technique scheme, fuel-displaced A mouth and fuel-displaced B mouth are respectively used to reverse hydraulic fluid port and the forward hydraulic fluid port of connecting bolt oil cylinder；Achieve the switching to plugging pin oil cylinder oil transportation direction by arranging solenoid directional control valve in valve block, be can be implemented in after the external part of plugging pin oil cylinder stretches out by hydraulic lock and plugging pin oil cylinder is carried out self-locking。
Being additionally provided with overflow valve in described valve block, described check valve also connects the oil-in of described overflow valve, and the oil-out of described overflow valve connects described oil return T mouth。By arranging overflow valve, it is possible to achieve the hydraulic fluid pressure entering plugging pin oil cylinder is adjusted。
In a specific embodiment, described overflow valve is to insert formula overflow valve。
It addition, described valve block also has detection X mouth, detection Y mouth, detection M mouth, detection N mouth；Described check valve is respectively communicated with described detection X mouth and described detection Y mouth；Described first unidirectional adjustable throttling connection described detection M mouth, described second unidirectional adjustable throttling connection described detection N mouth。Described detection X mouth, described detection M mouth and described detection N mouth are all for Bonding pressure table, and described detection Y mouth is used for Bonding pressure sensor。As such, it is possible to each hydraulic pressure point of valve block assembly is carried out pressure detection, know the operation conditions of hydraulic block device。
By foregoing detailed description it can be seen that this utility model has simple in construction, convenient switching oil transportation direction and the plugging pin oil cylinder stretched out carries out self-locking and to the adjustable advantage of fuel transfer pressure。
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, this utility model is described in detail:
Fig. 1 is valve block assembly schematic diagram of the present utility model。
Detailed description of the invention
As shown in Figure 1, plugging pin oil cylinder valve block assembly of the present utility model, including valve block (in figure shown in dotted line), it is located at the check valve 11 in valve block, solenoid directional control valve 16, hydraulic lock 19, first unidirectional adjustable throttling the 271, second unidirectional adjustable throttling 272, inserts formula overflow valve 13。Hydraulic lock 19 is made up of two check valves, the forward hydraulic fluid port mutual induction of two check valves in hydraulic lock 19, as long as the forward hydraulic fluid port of one of them check valve has pressure to be opened, the pressure that the forward hydraulic fluid port of another one check valve also can be sensed simultaneously is opened, and namely hydraulic lock 19 has two check valves and opens the function simultaneously closed off simultaneously。
Described valve block has oil-feed P mouth, fuel-displaced A mouth, fuel-displaced B mouth, oil return T mouth, surveys X mouth, detection Y mouth, detection M mouth and detection N mouth。
Oil-feed P mouth is communicated to the first hydraulic fluid port of described solenoid directional control valve 16 and the oil-in of slotting formula overflow valve 13 through check valve 11, second hydraulic fluid port of solenoid directional control valve 16 is communicated to fuel-displaced A mouth through one of them check valve of hydraulic lock 19, the first unidirectional adjustable throttling 271, and the 3rd hydraulic fluid port of solenoid directional control valve 16 is communicated to fuel-displaced B mouth through another check valve of hydraulic lock, the second unidirectional adjustable throttling 272；4th hydraulic fluid port of solenoid directional control valve 16 connects oil return T mouth with the oil-out of slotting formula overflow valve 13。
Check valve 11 is also respectively communicated with detection X mouth and described detection Y mouth；First unidirectional adjustable throttling 271 also connects detection M mouth, and the second unidirectional adjustable throttling 272 also connects detection N mouth。
In technique scheme, fuel-displaced A mouth and fuel-displaced B mouth are respectively used to reverse hydraulic fluid port and the forward hydraulic fluid port of connecting bolt oil cylinder 22；Achieve the switching to plugging pin oil cylinder 22 oil transportation direction by arranging solenoid directional control valve 16 in valve block, be can be implemented in after the external part of plugging pin oil cylinder 22 stretches out by hydraulic lock 19 and plugging pin oil cylinder 22 is carried out self-locking。
By arranging slotting formula overflow valve 13, it is possible to achieve the hydraulic fluid pressure entering plugging pin oil cylinder 22 is adjusted。
Detection X mouth, described detection M mouth and described detection N mouth are all for Bonding pressure table 17, and detection Y mouth is for Bonding pressure sensor 14。As such, it is possible to each hydraulic pressure point of valve block assembly is carried out pressure detection, know the operation conditions of hydraulic block device。
