Embodiment
Below, structure of the present invention and running principle will be described with reference to the drawings.
Fig. 1 shows the front elevation of the structure of reduction valve according to the embodiment of the present invention.Fig. 2 shows the side view of the structure of reduction valve according to the embodiment of the present invention.Fig. 3 shows the sectional view of the structure of reduction valve according to the embodiment of the present invention, and wherein reduction valve is in dish closed state.Fig. 4 shows the sectional view of the structure of reduction valve according to the embodiment of the present invention, and wherein reduction valve is in dish opening state.
As shown in the figure, in reduction valve 1 according to the present invention, diaphragm type cylindrical filter 4 is arranged in the fluid inlet apertures 3 of valve body 2.Filter 4 is externally installed around dish 6 with the shape of tubular, here description dish 6 subsequently.In other words, filter 4 has the cylindrical form of hollow, and in this cylindrical form, holding tray 6.
And, control fluid and be arranged on movably On/Off hole 7 to the mobile dish 6 of exit orifice 5 from inlet hole 3, making to coil 6 can vertically move up and down.The springs 8 that dish 6 is installed in dish lower end are bias voltage upwards flexibly.The upper end of dish 6 is connected to piston 9.
The upper end of piston 9 is connected to the lower end of diaphragm 11, and this diaphragm 11 is passed the pressure actuated of fluid that control valve 10 introduces, and this control valve 10 is arranged on the upper end of valve body 2.
That is to say, fluid can flow to control valve 10 by the control lead 12 being communicated with a side of inlet hole 3.And control valve 10 can be incorporated into the fluid with the force value of being preset by adjusting knob 13 in the diaphragm chamber 14 forming on the top of valve body 2.
In the upper end and the contact segment between diaphragm 11 of piston 9, mounting safety valve 15 makes as shown in the figure, when the pressure of the inlet fluid of introducing by the first side (being inlet hole 3) equals or exceeds preset reference pressure, safety valve 15 guides to hydrodynamic pressure in sensing pipe 18, and fluid flows through the second side (being exit orifice 5); The diaphragm 11 that moves up thus, and therefore discharge the unnecessary pressure that surpasses preset reference pressure.
In exit orifice 5, pressure meter 16 is installed, and this pressure meter 16 detects the pressure of the fluid of discharging by the second side.Pressure meter 16 is incorporated in the runner of exit orifice 5, and making does not need pressure meter 16 to be arranged on relief line individually.
In the lower end of valve body 2, expulsion valve 17 is installed, and this expulsion valve 17 is discharged the residuary waters of staying in valve body 2 or is discharged the air that the fluid from valve body 2 produces.In expulsion valve 17, on the outer circumferential face of valve body 17c, be formed with male thread portion 17a, this valve body 17c is engaged and is locked to valve chest 17d by thread type, make valve body 17c can be in response to the operation of Joystick 17b closure or openness runner.Here, as shown in Figure 5, in a part for whole length of the valve body 17c of expulsion valve, form male thread portion 17a, the valve body 17c that prevents thus expulsion valve is by wrongly installed or lose.
The reduction valve 1 with said structure can be used in the relief line of engine generator of ship effectively, especially, filter 4, safety valve 15, pressure meter 16 and expulsion valve 17 integrate and forming unit with reduction valve 1, make the mounting zone of reduction valve to be minimized by reducing the volume of product, and can realize light and the simple installation process of equipment therefor in relief line.
In the initial period, reduction valve 1 of the present invention is standby with closed state.When fluid flows in valve by inlet hole 3 (i.e. the first side), fluid flow to control valve 10 by control lead 12, and inlet fluid flow to diaphragm chamber 14 with the default head pressure value of control valve 10.Therefore, diaphragm 11 moves downward because hydrodynamic pressure moves downward and make piston 9, and the dish 6 being connected with the lower end of piston 9 is promoted by piston 9, therefore, by spring 8 flexibly upwards the dish 6 of bias voltage move downward.Therefore, as shown in Figure 4, reduction valve 1 is unlocked, and fluid is discharged into the second side to preset head pressure by exit orifice 5.
In the present invention, filter 4 is installed in reduction valve 1, and making does not need individually filter to be arranged in the front and rear of relief line.And pressure meter 16 is installed in the exit orifice 5 of valve body 2, makes to be easy to measuring pressure.And, for discharge the expulsion valve 17 of residual water and air from the inside of valve body 2, be arranged on the lower end of valve body 2, make to remove the factor that can disturb the operation of reduction valve 1.And, in a part for the valve body of expulsion valve, be formed with male thread portion 17a, make when the expulsion valve 17 of valve body 2 inside is opened, expulsion valve 17 can not removed completely, therefore, can prevent that expulsion valve 17 is lost in ship.And when the pressure of inlet fluid surpasses preset pressure, safety valve 15 can automatically discharge the pressure exceeding, and realizes thus the Safety function of reduction valve.
Although for illustrative object discloses embodiments of the present invention, it will be understood by those skilled in the art that and do not departing under scope and spirit of the present invention as disclosed in the claim appended, various modification, to increase and replace be possible.
Industrial applicibility
As mentioned above, the present invention relates to a kind of reduction valve.Especially, while reduction valve of the present invention being installed in the relief line at ship, weight, quantity and the mounting zone that can make to be arranged on the device in relief line minimize, and can reduce production costs, and can also improve the efficiency of management.Therefore, reduction valve of the present invention can be used in the haulage device for example in ship with limited mounting zone effectively, and can effectively be suitable for shipbuilding industry.
