Described valve rod 24 to be placed through in described valve pocket 11 and can to move up and down in this valve pocket 11; Described spring seat 5 is fixedly connected with described valve rod 24 by the transition cone block 6 of two halves structure, and the described transition cone outer poppet surface of block 6 and the inner cone surface engagement of described spring seat 5 are processed, to ensure certain area of contact.Described spring 8, by being fixed on spring seat 5 on described valve rod 24 by this valve rod 24 upwards ejection, making the valve head conical surface of described valve rod 24 bottom match with the conical surface of described valve seat 9 and contacts, and described first inner cavity chamber 110 and the second inner cavity chamber 100 are cut off; The valve head conical surface of described valve rod 24 and the cone match of described valve seat 9 are processed, can reach sealing contact.
Described moving electromagnetic valve receives the start signal of described marine diesel engine control system, high-pressure air imported to the chamber 401 between described valve gap 4 and piston 23 by described air outlet hole 210 and inlet hole 200, the air pressure acted on this piston 23 overcomes the spring force of described spring 8, and make this piston 23 promote described valve rod 24 to move downward, thus described valve rod 24 is departed from valve seat 9, and be communicated with described first inner cavity chamber 110 and the second inner cavity chamber 100, thus described main starting valve is in open mode.Described moving electromagnetic valve receives the shutdown signal of described marine diesel engine control system, cut off the high-pressure air entering described inlet hole 200, described spring 8 drives described valve rod 24 to move upward by described spring seat 5, make the valve head conical surface of described valve rod 24 and the conical surface close contact of described valve seat 9, and described first inner cavity chamber 110 and the second inner cavity chamber 100 are cut off, thus described main starting valve is in closed condition.
Described locking mechanism is arranged on described valve gap 4, and this locking mechanism comprises check lock lever 1, sleeve 31, push rod 2 and snubber 3.Described check lock lever 1 is threaded connection 1 top of described piston 23, this check lock lever 1 periphery has upper groove 101 and low groove 102.Described sleeve 31 is welded and fixed with described valve gap 4, is provided with screw thread in its endoporus; Described push rod 2 seesaws wherein by being threaded into this sleeve 31, and the top of this push rod 2 can be inserted in described upper groove 101 or low groove 102, realizes locking and the unblock of described main starting valve respectively.Described snubber 3 is fixed on the side of described valve gap 4, is provided with bulb P, and the periphery of described push rod 2 is provided with arc groove, and the bulb P of this snubber 3 can slip in this arc groove.
The working principle of diesel engine for ship main starting valve of the present invention is as follows:
When diesel engine long-term inoperative time, main starting valve is in locking state, the step of locking main starting valve is as follows: manually by check lock lever 1 and piston 23 screwed tight, simultaneously by the screw thread of push rod 2 precession sleeve 31, now the top of push rod 2 can be inserted in the upper groove 101 of check lock lever 1, push rod 2 is in the process of precession sleeve 31, the bulb P of snubber 3 slips into the bottom of the arc groove of push rod 2, now bulb P is in releasing orientation, and diesel engine centralized control system can receive a current index signal being in locking state.
When diesel engine needs to start, high-pressure air enters in the first inner cavity chamber 110 by starting air manifold, and one high-pressure air has entered in moving electromagnetic valve by the air outlet hole 210 of valve body 20 simultaneously, is in wait state.Main starting valve completes unblock by following unlocked step: manually push rod 2 is screwed out sleeve 31, push rod 2 top is exited from the upper groove 101 of check lock lever 1, again check lock lever 1 is manually upwards screwed out, after throwing off with the screw thread of piston 23, again by push rod 2 precession sleeve 31, the top of push rod 2 is made to be inserted in the low groove 102 of check lock lever 1, now main starting valve has unlocked, the bulb P of snubber 3 slides into top from the bottom of the arc groove of push rod 2 simultaneously, bulb P is in impaction state, and diesel engine centralized control system receives a current index signal being in released state.
After diesel engine centralized control system has given moving electromagnetic valve start signal, the high-pressure air waited in a moving electromagnetic valve just enters in the chamber 401 between valve gap 4 and piston 23 by the inlet hole 200 of valve gap 4, the spring force promotion valve rod 24 being overcome spring 8 by the pressure acted on piston 23 is moved downward, now valve rod 24 and valve seat 9 are thrown off, starting valve is in open mode, waits for that the high-pressure air in the first inner cavity chamber 110 enters into by the second inner cavity chamber 100 starting air manifold leading to each cylinder.After playing moving electromagnetic valve and receive shutdown signal from diesel engine centralized control system, play moving electromagnetic valve the high-pressure air acted on piston 23 is cut off, now spring 8 is with ovable valve stem 24 to move upward by spring seat 5, now valve rod 24 the valve head conical surface overlap with the conical surface of valve seat 9, namely main starting valve is in closed condition.
If main starting valve does not use for a long time, repeat locking step and main starting valve is locked, avoid human operational error to be opened by main starting valve, to protect the safety of diesel engine.
Be more than a best embodiment of the present invention, can not limit the scope of the invention with this.What protection scope of the present invention also comprised other is apparent conversion for those skilled in the art and substitutes.
