Description
Technical field
The utility model relates to a kind of GVU valve box structures.
Background technique
GVU clack box be equipped with electromagnetic valve component, as on LNG powered ship for control or reconcile gaseous propellant engine it
Preceding valve member and tubing device equipment, this kind of GVU valve box structure have the following problems: (1) since ship under sail shake greatly,
The gas supply tube end of electromagnetic valve component is all to directly adopt screw thread to dock with host in LNG powered ship GVU clack box at present, this
Connection structure is easy to fall off；(2) the gas supply tube end of electromagnetic valve component and host junction are shaken by long-time in GVU clack box
It is easy to happen the leakage of LNG gas even, cannot be excluded in time after leakage, influence LNG powered ship normal/cruise and fail- safe.
(3) when past host is shut down with gas, the extra LNG gas in steam line can be discharged, desorption tube is often placed into single
In pipeline, it is connected to the outer safe release region of ship side.
Summary of the invention
Purpose of the utility model is to solve above-mentioned technical problem, provide that a kind of structure is simple, is easy to be transformed, safety
Reliably, the long GVU valve box structure for LNG powered ship of service life of equipment.
Technical solution include be equipped with electromagnetic valve component cabinet, the electromagnetic valve component be equipped with air inlet pipe and with host air inlet
The air supply pipe of mouth connection, the bottom of box set air inlet, and top sets out air port, are additionally provided on the cabinet and host body connects
The sealing sleeve pipe connect, the sealing sleeve pipe are sleeved on outside air supply pipe, and the air inlet and the end of the sealing sleeve pipe are also connected with
There is backwind tube.
The gas supply pipe end is equipped with host air inlet connecting flange and corresponding gasket seal, the sealing sleeve pipe end
Equipped with host body connecting flange.
The air supply pipe is also connect through electromagnetic valve component with desorption tube, and the desorption tube outlet is located at the air outlet of cabinet
Place.
The bottom of the cabinet is equipped with shock bracket.
The utility model has the advantages that
1) end of import and sealing sleeve pipe is connected by backwind tube, is divided into two strands by the wind that air inlet enters, one
It is directly blown into cabinet, one is then sent into sealing sleeve pipe through backwind tube, blows the junction of air supply pipe and host air inlet
It send, when the leakage of host air inlet connecting flange position, the gas of leak site can be quickly blown to air outlet, cabinet is discharged
Outside, any security risk is avoided.
2) gas supply tube end is docked with the screw thread of host and is changed to flanged joint, junction under Long-term Vibration is avoided to occur to take off
It falls, further increases the security reliability of vessel motion.
3) the desorption tube nozzle of electromagnetic valve component is placed at the air outlet of cabinet, utilizes the airflow effects of box air outlet
Dilution pernicious gas rapidly, existing unsafe factor, improves precautionary measures when desorption tube being avoided to diffuse.
4) the utility model structure is simple, be easy to be transformed, security and stability is good.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Wherein, 1- host air inlet connecting flange, 2- host body connecting flange, 3- backwind tube, 4-GVU connecting flange,
5- electromagnetic valve component, 6- air supply pipe, 7- cabinet, 8- gasket seal, 9- desorption tube, 10- air inlet pipe, 11- sealing sleeve pipe, 12- into
Air port, 13- air outlet, 14- shock bracket.
Specific embodiment
Explanation is further explained to the utility model with reference to the accompanying drawing:
Referring to Fig. 1, cabinet 7 is provided with electromagnetic valve component 5, and it can be cabinet that the bottom of the cabinet 7, which is equipped with shock bracket 14,
7 dampings.The air supply pipe 6 that the electromagnetic valve component 5 is equipped with air inlet pipe 10 and connect with host air inlet, 7 bottom of cabinet
If air inlet 12, top sets out air port 13, and the sealing sleeve pipe 11 connecting with host body is also connected on the cabinet 7, described
Sealing sleeve pipe 11 is sleeved on outside air supply pipe 6, and one end of the sealing sleeve pipe 11 is connect through GVU connecting flange 4 with cabinet 7, another
End is connect through host body connecting flange 2 with host body, and the air inlet 12 and the end of the sealing sleeve pipe 11 are also connected with
There is backwind tube 3,6 end of air supply pipe is equipped with host air inlet connecting flange 1 and corresponding gasket seal 8, the air supply pipe 6
It is also connect through electromagnetic valve component 5 with desorption tube 9, the outlet of desorption tube 9 is located at 13 at the air outlet of cabinet 7.
Gas in air inlet pipe 10 through electromagnetic valve component 5, air supply pipe 6 through host air inlet connecting flange 1 be sent into host into
Port (not shown)；The ventilation of air inlet 12 of cabinet 7 is divided into two strands, one ventilation is sent into cabinet 7 again through air outlet 13
Discharge, another burst of ventilation are discharged by air outlet 13 again after backwind tube 3, sealing sleeve pipe 11 enter cabinet 7；When 6 end of air supply pipe
Host air inlet connecting flange 1 loosens, and when managing interior gases did escape, gas will not be retained but locally quickly by not open close
The wind entered is brought to air outlet 13 and is discharged.
When main shut-down system, the gas in air supply pipe 6 is discharged through electromagnetic valve component 5 by desorption tube 9, due to air outlet 13
Around desorption tube 9, and the presence of constant ventilation is improved there are unsafe factor when release can be effectively protected
The reliability of precautionary measures.
