In order to realize above-mentioned technical characteristic, draw purpose of the utility model is realized as follows: a kind of governor master matches
Pilot valve oil leak monitoring and collection device, it includes main with shell, and the master is equipped with main with valve deck, institute with the top braces of shell
It states the main center with valve deck and main dispensing spool is installed, the inside of the main dispensing spool is equipped with guidance valve core, is guiding
The outside of valve core is set with guiding valve bushing by being slidably matched, and the guidance valve liner is fixed on the inside of main dispensing spool,
Multiple guiding valve valve core pistons are provided on the guidance valve core, two annular chambers of the master with valve deck match valve with main respectively
Guiding valve control chamber and guiding valve pressure oil source chamber are formed between the outer wall of core, the master matches the top annular chamber of valve deck, and position
Leaked fuel collection chamber is formed in the top of guiding valve pressure oil source chamber；Leakage oil collection pipe is connected on the leaked fuel collection chamber.
The guiding valve valve core piston is slidably matched with guidance valve liner composition, is provided on the guiding valve valve core piston
Seal groove is equipped with sealing ring on the seal groove.
The horizontal segment of the leakage oil collection pipe uses transparent communicating pipe, is equipped with flowmeter on the transparent communicating pipe.
The other end of the leakage oil collection pipe is led in oil return tank of speed controller.
The utility model has the advantages that:
1, simple in construction, easy to disassemble and assemble: only one leaked fuel collection chamber, and skirt need to be set on guiding valve pressure oil cavity top
Road can realize the collection to leakage of oil in guiding valve action process, collecting is detachable to oil return box.
2, principle is simple: main with leaked fuel collection chamber and leakage oil collection pipe is increased above guiding valve pressure oil source chamber, preventing
Leakage of oil spills into main on valve deck in guidance valve core action process.Visual pipe and flowmeter are arranged on leakage oil collection pipe to supervise
Leakage is surveyed, guides sealing condition for quickly judging.
3, practical: to increase governor main control valve operational reliability, master can be assessed by the monitoring to oil leak amount and matched
The sealing state of pressure valve guiding valve.Leakage of oil by leakage oil collection pipeline recycling after, can avoid oil leaking pollution environment the problem of.
4, application space is extensive: can be widely applied to turbine-generator units or water pump turbine-generator units and fills with guiding valve
The speed-regulating system set.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is the utility model of the whole structure diagram.
In figure: main to match valve deck 2, main dispensing spool 3, guidance valve liner 4, guidance valve core 5, guidance valve core with shell 1, master
Piston 6, transparent communicating pipe 7, flowmeter 8, leakage oil collection pipe 9, leaked fuel collection chamber 10, guiding valve pressure oil source chamber 11, guiding valve
Control chamber 12, sealing ring 13.
Specific embodiment
The embodiments of the present invention is described further with reference to the accompanying drawing.
Referring to Fig. 1, a kind of governor master matches guiding valve oil leak monitoring and collection device, it includes main with shell 1, described
The main top braces with shell 1 are equipped with master with valve deck 2, and the master is equipped with main dispensing spool 3, institute with the center of valve deck 2
The inside for stating main dispensing spool 3 is equipped with guidance valve core 5, is set with guidance by being slidably matched in the outside of guidance valve core 5
Valve liner 4, the guidance valve liner 4 are fixed on the inside of main dispensing spool 3, are provided with multiple guidance on the guidance valve core 5
Valve core piston 6, two annular chambers of the master with valve deck 2 form guiding valve control between the outer wall of main dispensing spool 3 respectively
Chamber 12 and guiding valve pressure oil source chamber 11, the master matches the top annular chamber of valve deck 2, and is located at guiding valve pressure oil source chamber 11
