Description

COMBINED VALVE BLOCK FOR CONTROLLING FLUID
The present invention relates to a combined valve block for controlling a fluid, and more particularly to, a combined valve block for controlling a fluid in which flow path grooves and cross grooves of a flow path plate and an adjustment path are separately manufactured for different flows of the fluid and a distance between flows is minimized by combining and assembling a flow rate plate, the flow path plate, and the adjustment path, thereby minimizing a dead volume of the fluid that occurs in a distance between valves and achieving smooth flows.
In general, a flow control valve for controlling a flow operates according to a pressure difference. Among many flow valves operating according to the pressure difference, a valve including a hemispherical yieldable membrane is disclosed in the prior patents US No. 2,980,385 of E.J. Hunter, US No. 3,493,008 of P.J. Scaglione, US Serial No. 08/545,890 of S. Perez, and US No. 2,980,385 of Hunter. Since a wall of the valve is relatively thick, when a pressure in a concave portion of the valve is quite high, the membrane is not locked in a flow outlet. However, an excessive thickness of the wall prevents the valve from reacting with respect to a minor pressure difference, the valve may be permanently closed without discharging a flow required when the valve is slightly opened, or a very small amount of flow may be discharged.
The US No. 3,493,008 of P.J. Scaglione discloses a valve including a disk type cup and a valve active device including a metallic bellow that is welded, sealed, and flexible. A wall of the metallic and flexible bellow easily reacts according to a pressure difference in both sides of the wall and thus the wall is crushed when an inner pressure is higher than an outer pressure. Thus, it is required to devise a bellow having a more resistive wall when operating at a high pressure, and thus a valve having a low sensitivity according to a minor pressure change is obtained.
Meanwhile, the disk type cup is basically hard. A sealing apparatus of the disk type cup loses efficiency when a flow in a pipe carries impurities along with a valve sheet. In addition, a substantial loss of load occurs due to a valve structure.
In the conventional technology operating according to a pressure difference, the valve mainly has a complex structure which causes a considerable load loss, and has a very small flexibility with respect to a flow pressure in the pipe. In other words, such a valve is designed to adjust a flow within a small range of pressure and thus loses efficiency with respect to a considerable pressure change in the pipe.
The US Serial No. 08/545,890 of S. Perez discloses a differential valve that is sensitive to a minor pressure change and is resistive with respect to a considerable operating pressure, which includes few elements and thus can be very simply devised. The differential valve shows a hard valve body including a flow inlet opening and a flow outlet positioned to almost cross the flow inlet opening. The valve body includes a main cavity between a flow inlet and the flow outlet, and a valve sheet in a boundary of the main cavity and the flow inlet. The valve body includes a control flow outlet pipe connected to a control flow transmission means of the valve. The valve includes an elastomeric body positioned in the main cavity of the valve. The elastomeric body is hollow and has axial end portions in which one of the axial end portions is opened and a center opening portion is provided in another axial end portion.
The center opening portion transmits the control flow inlet to the main cavity. The flow has the same property as that of a flow of a network in which the valve operates.
Although the last type valve is useful and simply devised, the valve cannot use a control flow that is indispensable to an automatic control apparatus or an apparatus which needs to control a great amount of control flow by using a weak signal if the control flow is different from the flow of the network. Although the present invention includes some elements disclosed in the US Serial No. 08/545,890, the present invention includes a control flow inlet mean independent from a main flow of the network, thereby obtaining actuating dynamics for a valve completely different from the valve of the conventional technology.
However, a hole disposed in a sealing wall of the elastomeric body of the valve has a predetermined cross-section, and thus the above element problematically cannot change a flow. Even though the flow is changed, it is difficult to problematically adjust a minute flow.
In addition, it is difficult to control the minute flow to a minimum movement distance by using a great number of valves, which problematically causes a frequent occurrence of a dead volume.
The present invention provides a combined valve block for controlling a fluid in which flow path grooves and cross grooves of a flow path plate and an adjustment path are separately manufactured for different flows of the fluid and a distance between flows is minimized by combining and assembling a flow rate plate, the flow path plate, and the adjustment path, thereby minimizing a dead volume of the fluid that occurs in a distance between valves and achieving smooth flows.
The technical goal of the present invention is not limited thereto.
According to an aspect of the present invention, there is provided a combined valve block for controlling a fluid including: a flow rate plate formed in a plate shape, comprising through holes formed to penetrate from the outside of one side surface to another side surface and a plurality of fluid tubes connected to an entrance of the through holes of the other side surface; a first sheet stacked on one side of the flow rate plate, comprising through holes formed in the same locations of the plurality of through holes, and formed in a sheet shape; a flow path plate stacked in one side of the first sheet and coupled thereto, comprising a plurality of through holes penetrating from one side to another side at the same locations as those of the plurality of through holes and a plurality of flow path grooves formed in one side surface in a length direction; a second sheet stacked on one side of the flow path plate and comprising a plurality of through holes in the outside at the same locations as those of the plurality of through holes of the flow path plate; and an adjustment plate stacked on one side of the second sheet, comprising a plurality of pores on a front surface at a uniform space, a plurality of cross grooves in another side surface to cross the plurality of flow path grooves of the flow path plate, an inlet hole and an outlet hole formed in an outer side surface, and a plurality of valves coupled to one side surface.
The first sheet may seal between the flow rate plate and the flow path plate to enable the fluid not to flow between the flow rate plate and the flow path plate.
The plurality of flow path grooves formed in one side surface of the flow path plate may be formed in a length direction and shorted in one end side of the flow path plate, and the flow path groove in the outermost side may extend to an edge side of the flow path plate.
The second sheet may seal between the flow path plate and the adjustment plate and simultaneously enable the plurality of flow path grooves and the plurality of cross grooves to operate hydraulically or pneumatically and open and close.
Two of the plurality of pores of the adjustment plate may be diagonally formed to form a module, the two pores configured as the module may be formed along the plurality of cross grooves, and one of the two pores configured as the module may be formed to penetrate the plurality of cross grooves.
As described above, the present invention is advantageous that flow path grooves and cross grooves of a flow path plate and an adjustment path are separately manufactured for different flows of the fluid and a distance between flows is minimized by combining and assembling a flow rate plate, the flow path plate, and the adjustment path, thereby minimizing a dead volume of the fluid that occurs in a distance between valves and achieving smooth flows.
The present invention is also advantageous that a line through which a flow flows is configured to fully drain an internal fluid by providing an inclination to the line, and a control block is configured to freely take in and out the fluid according to shapes of flow path grooves and cross grooves, thereby preventing fluids from being mixed and minimizing a dead zone in a fluid flow.

The present invention will now be described more fully with reference to the accompanying drawings. In the drawings, like reference numerals denote like elements. While describing the present invention, detailed descriptions about related well known functions or configurations that may blur the points of the present invention are omitted.
FIGS. 1 and 2 are diagrams of a combined valve block for controlling a fluid according to an embodiment of the present invention. The combined valve block for controlling the fluid includes a flow rate plate 10 in which a plurality of through holes 1 are formed outside from one side surface to another side surface and a plurality of fluid tubes are connected to an entrance of the through holes 1 of another side, a first sheet 20 stacked on one side of the flow rate plate 10, a flow path plate 30 stacked on one side of the first sheet 20 and in which a plurality of flow path grooves 31 are formed in one side surface in a length direction, a second sheet 40 stacked on one side of the flow path plate 30, and an adjustment plate 50 stacked on one side surface of the second sheet 40 and in which a plurality of cross grooves 51 and a plurality of pores 52 are formed.
The flow rate plate 10 is formed in a plate shape, includes the through holes 1 formed to penetrate from the outside of one side surface to another side surface, and the plurality of fluid tubes connected to the entrance of the through holes 1 of the other side surface. The fluid injected through the through holes 1 has a uniform amount when flowing to one side due to a size of the through holes 1, and thus a quantitative amount of fluid is supplied to the flow path plate 30 and the adjustment plate 50.
As shown in FIG. 3, the first sheet 20 stacked on one side of the flow rate plate 10 is formed in a plate shape, and is formed of a sealable material such as rubber, vinyl, or plastic, for sealing between the flow rate plate 10 and the flow path plate 30.
As shown in FIGS. 4 and 7, the through holes 1 are formed in the first sheet 20 at the same locations as those of the through holes 1 of the flow rate plate 10 through which the fluid injected through the through holes 1 of the flow rate plate 10 flows and is supplied to the flow path plate 30.
The plurality of through holes 1 are formed in the flow path plate 30 at the same locations as those of the through holes 1 of the first sheet 20, and the plurality of flow path grooves 31 are formed in one side surface in the length direction. Internal locations of the flow path grooves 31 are shorted in one side of the flow path plate 30 at a uniform space such that the fluid may not flow.
In this regard, one end side of the flow path grooves 31 formed in one end side of the flow path plate 30 is formed in a diagonal direction such that the flow path grooves 31 correspond to the pores 52 at a dislocated location of the adjustment plate 50 stacked on one side surface other than the pores 52 at a corresponding location thereof.
The flow path groove 31 disposed at the outermost among the flow path grooves 31 at one end side of the flow path plate 30 extends in a longitudinal direction of one end side.
The second sheet 40 is stacked on one side surface of the flow path plate 30, seals between the flow path plate 30 and the adjustment plate 50, includes the through holes 1 corresponding to the through holes 1 formed in the flow path plate 30, and enables the fluid to flow to the cross grooves 51 of the adjustment plate 50.
The second sheet 40 seals between the flow path plate 30 and the adjustment plate 50 and simultaneously enables the flow path grooves 31 and the cross grooves 51 to operate hydraulically or pneumatically and open and close.
The adjustment plate 50 is stacked on one side surface of the second sheet 40, and includes the pores 52 formed to penetrate from one side surface to another side surface. The two pores 52 are adjacent to each other and are configured as a module. The pores 52 configured as the module are arranged in the diagonal direction. The cross grooves 51 are formed across the flow path grooves 31 of the flow path plate 30 in another side surface. The lower pore 52 of the pores 52 configured as the module is formed to penetrate the cross grooves 51. A plurality of inlet and outlet holes that are connected to the cross grooves 51 are formed in an outer side surface.
A plurality of valves 60 are coupled to one side surface of the adjustment plate 50, and are coupled to the pores 52 to allow the second sheet 40 to close and open the cross grooves 51 and the flow path grooves 31 at a fluid or gas pressure such that the fluid may flow in a desired direction.
The valves 60 may use solenoid valves 60 or diaphragm valves 60.
An inlet hole and an outlet hole are formed in an outer side of the flow path plate 30 of the present invention configured above so that the fluid that passes through the flow path grooves 31 of the flow path plate 30 may be injected and discharged.
A method of controlling a flow of the fluid through the valves 60 according to the present invention configured above is as follows.
If the fluid is supplied to the cross grooves 51 of the adjustment plate 50 through the flow rate plate 10, the first sheet 20, the flow path plate 30, and the second sheet 40 by connecting the fluid tubes to the through holes 1 of the flow rate plate 10, the second sheet 40 reciprocally moves between the flow path grooves 31 and the cross grooves 51 through the valves 60 coupled to one side surface of the adjustment plate 50, the fluid flows by control of the valves 60, and thus the flow is controlled.
The controlled fluid may be mixed with another fluid that is discharged or injected through the inlet and outlet holes formed in the outer side surface of the adjustment plate 50.
The present invention configured above is advantageous that flow path grooves and cross grooves of a flow path plate and an adjustment path are separately manufactured for different flows of the fluid and a distance between flows is minimized by combining and assembling a flow rate plate, the flow path plate, and the adjustment path, thereby minimizing a dead volume of the fluid that occurs in a distance between valves and achieving smooth flows.
The present invention is also advantageous that a line through which a flow flows is configured to fully drain an internal fluid by providing an inclination to the line, and a control block is configured to freely take in and out the fluid according to shapes of flow path grooves and cross grooves, thereby preventing fluids from being mixed and minimizing a dead zone in a fluid flow.
The above-described combined valve block for controlling a fluid is not limited to the configurations and operating methods of the embodiments described above. The above embodiments may be configured such that various changes may be made by wholly or partially combining the embodiments alternatively.
