Brief description of the drawings
Fig. 1 is that the structure that the utility model has pressure charging valve in the dry net cleaning device of the paper machine of automatic oil draining pressure charging valve is shown
It is intended to.
Fig. 2 is the diagrammatic cross-section of A-A in Fig. 1.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.
As illustrated in fig. 1 and 2, the utility model provides a kind of paper machine with automatic oil draining pressure charging valve dry net cleaning dress
Put, the dry net cleaning device of the paper machine with automatic oil draining pressure charging valve include a control device (not shown), pressure charging valve 10,
Draining valve 20 and the cleaning shower nozzle (not shown) for being connected to pressure charging valve 10, the pressure charging valve 10 and draining valve 20 are all connected to described
On control device, the pressure charging valve 10 is provided with an oil discharge outlet 11, and the draining valve 20 is arranged at the oil discharge outlet 11, described
Draining valve 20 controls the open and close of the oil discharge outlet of pressure charging valve 10.
The pressure charging valve 10 includes main part 12 and the connector 13 being installed on main part 12, high pressure water outlet piece 14, low
Water inflow 15 is pressed, the main part 12 includes cylinder body 121, is installed in the cylinder seat 122 and valve element 123 of the both sides of cylinder body 121, the valve
Core 123 is installed in cylinder body 121 and extended in two cylinder seats 122.The oil discharge outlet is arranged on the top surface of cylinder body, and passes through pipe
Road is connected in fuel tank, and the draining valve is installed in the oil discharge outlet position, so as to the oil of oil discharge outlet is expelled in fuel tank or
Closing oil discharge outlet avoids hydraulic oil from discharging.The bottom of the main part 12 is provided with some shockproof pin 124, so that pressure charging valve 10
Installation is more firm.
Delivery port 141 and outlet conduit 142 are provided with the high pressure water outlet piece 14.Set on the low pressure water inflow 15
There are water inlet 151 and inlet channel 152, be provided with a chamber in the cylinder seat 122, the inlet channel 152 is provided with two pipelines
It is respectively communicated with being provided with low pressure check valve 30 in the pipeline in two chambers, and between inlet channel 152 and chamber.The outlet pipe
Two pipeline communications are also equipped with road 142 in being provided with height in the pipeline in two chambers, and between the outlet conduit 142 and chamber
Press check valve 40.
The connector 13 is arranged on the top surface of main part 12, and it is used to connect external fuel tank, is set on connector 13
Have oil inlet 131 and an oil-out 132, it is described enter oil product 131 and oil-out 132 be all connected on the valve element 123.The valve element
A pilot hole (not shown) is provided with 123, is provided with a reversal valve in valve element 123, hydraulic oil enters to from the oil inlet 131
In valve element 123, and valve element 123 is promoted to run, so as to which the commutation of reversal valve can be realized.Hydraulic oil promotes valve element 123 to run to the left
When, the low pressure water in inlet channel 152 is entered in cylinder seat chamber from left side low pressure check valve 30, and unidirectional by left side high pressure
Valve 40 is entered in outlet conduit 142, then is discharged from delivery port 141；When hydraulic oil promotes to the right the operation of valve element 123, low pressure water
Enter outlet conduit 142 through right side low pressure check valve 30, high pressure check valve 40, then discharged from delivery port 141.
Due to having a segment distance between cleaning shower nozzle and dry net, so as to start the run signal of dry net cleaning with starting high pressure
Water valve carries out cleaning and one section of delay be present, it is impossible to start water under high pressure at once, therefore, the control device is provided with a delay time,
When control device sends run signal, the draining valve, which receives run signal and opens oil discharge outlet, carries out oil extraction, now, increases
Pressure valve is in oil extraction state, normal operation but can be in low-pressure state, after setting delay time and reaching, closing draining valve, makes
Pressure charging valve is completely into normal operating condition.So as to avoid the timely return in valve element end, lead to not normal startup pressure charging valve
Problem.
In summary, the utility model is existed by adding a draining valve at pressure charging valve oil discharge outlet with automatically controlling pressure charging valve
Oil extraction is carried out when starting every time, reduces loss of the hydraulic oil pressure to seal, extends the service life of seal.The same time
Processing time has been saved, has improved the security of staff's operation.It is of the present utility model practical, there is stronger popularization to anticipate
Justice.
