DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

(Example 1-1) The static pressure supply device of the present invention includes a static pressure vessel 100 forming a receiving space S1 with a press block 200; a first coupling unit 311; a second coupling unit 312; A first valve 300 for selectively opening and closing the first to third coupling ports by the first knob 320,

And a first connection pipe (331a) for connecting the accommodation space (S1) and the first coupling hole (311).

In an internal container for receiving a fluid, the fluid contained in the container causes pressure drop and vacuum generation inside the container depending on the use of the fluid, and pressure drop and vacuum cause resistance of the fluid discharge. To solve this problem, the container must maintain constant static pressure irrespective of fluid use.

The present invention is an invention for maintaining the pressure inside the container at a constant pressure without affecting fluid use. The static pressure vessel in which the fluid is received combines a pressurized block inside. The pressure block is moved inside the static pressure vessel.

The fluid supply of the accommodation space and the fluid discharge of the accommodation space are made up of a first connection pipe. That is, the first connection pipe supplies the fluid from the outside to the accommodation space, and also discharges the fluid in the accommodation space to the outside.

The first connection pipe is engaged with the first valve. The valve forms a first engagement hole, a second engagement hole, and a third engagement hole. The first coupling hole is coupled with the first coupling hole, the second coupling hole supplies the fluid from the outside, and the third coupling hole supplies the fluid in the water hole to the pressure supply device.

The first valve is equipped with a knob, the first actuation of the knob communicates the first engagement aperture and the second engagement aperture, the second actuation of the knob communicates the first joint and the third engagement aperture, The third operation closes the first to third engagement openings.

The fluid filling of the static pressure vessel connects the first coupling port with the first coupling port, and couples the fluid supply device (K) with the second coupling port, and the knob of the first valve is formed by the first operation. This causes the fluid of the fluid supply device to be charged into the accommodation space through the second connection pipe, the first valve, and the first connection pipe.

The process of supplying the fluid in the accommodation space to the pressure supply device P causes the knob of the first valve to perform the second operation because the fluid in the accommodation space communicates with the pressure supply device P, . Since the accommodation space maintains the static pressure, the pressure supply device is supplied at a constant pressure.

In order for the constant-pressure vessel to supply a constant pressure, the volume must be variable depending on the amount of fluid used. This is possible by moving the press block. That is, as the amount of fluid used is increased, the amount of movement of the press block increases, and the volume of the accommodating space gradually decreases.

(Example 1-2) The static pressure supply device of the present invention includes an O-ring 211, which is coupled to the press block and is in close contact with the inside of the static pressure vessel, in Example 1-1.

The pressure block is moved inside the static pressure vessel. The fluid in the receiving space can flow out between the contact surfaces of the static pressure vessel and the pressure block. The contact surface of the pressure block joins the O-ring to prevent fluid outflow. The O-rings are formed in plural and preferably 2 to 4 pieces.

(Embodiment 1-3) The static pressure supply device of the present invention includes the elastic plate 212 of Embodiment 1-1, which is coupled to the pressure block and is in close contact with the inner surface of the static pressure container.

An elastic plate is coupled to one side and / or the other side of the pressing block. The elastic plate is formed of rubber. The elastic plate is in close contact with the inner diameter of the static pressure vessel in an elastically deformed state. The direction of the elastic deformation changes according to the downward movement and the upward movement of the press block. The elastic plate is to prevent the fluid in the receiving space from flowing out through the pressure block.

(Embodiment 1-4) The static pressure supply device of the present invention is the static pressure supply device according to Embodiment 1-1, including a weight block 221 coupled to one side of the pressure block; Or a weight can (222).

In order to keep the pressure of the accommodation space constant, the press block is moved along the inside of the static pressure vessel. To apply a constant pressure, the press block is formed of a heavy metal. To increase the amount of pressurization, a weight block or a weight tank is coupled to the upper side of the pressurizing block. The weight block can control the load by a combination of a plurality of blocks, and the weight canteen can adjust the load according to the amount of water in the canteen.

In order to fixably connect the press block and the weight block, the press block forms a protruding bar at the center, and the weight block forms a hole for engaging the protruding bar inside. A male thread is formed on the outside of the projecting rod, and a coupling hole is internally threaded. Or with a separate nut to join the projecting rod.

The combination of the weight tube and the pressing block is fixed by a clip formed on the pressing block. The weight canteen forms a cap and the cap supplies or discharges water. The weight canteen is transparent and the amount of water inside can be visually confirmed. Weight You can check the amount of water on scale by forming a scale on the outer surface of the water bottle.

(Embodiment 1-5) The static pressure feeder of the present invention includes, in Embodiment 1-1, a separation chamber 121 coupled to the static pressure vessel opening and forming an air outlet 122.

In the process of filling the fluid in the accommodation space, when the fluid of the capacity or more is supplied, the press block may be released to the outside of the static pressure container. In order to prevent this, the separation chamber is coupled to the opening of the static pressure vessel. When the space between the escape opening and the press block is closed, the pressure of the closed space can be increased by the rise of the press block in the filling process. To prevent this, an air outlet is formed in the escape chamber. Therefore, the atmospheric pressure is always maintained between the escape prevention port and the pressure block.

(Examples 1-6) The static pressure supply device of the present invention includes the joining means 123 that is coupled to the outer surface of the escape chamber and the opening of the static-pressure container, in Example 1-5.

If the amount of fluid to be filled is excessive during the fluid filling process of the accommodation space, the pressure block may be released to the outside of the static pressure vessel, and if the pressure of the accommodation space is high, Can be separated. In order to prevent this, the departure prevention port and the static pressure vessel are fixed by a coupling means.

(Examples 1-7) In the static pressure supply device of the present invention, in the 1-6 embodiment, the engaging means is formed of any one selected from a screw connection, a groove and a projection.

The coupling means form a threaded connection. That is, the male thread is formed on the outer diameter of the release retainer, and the female screw is formed on the inner surface of the constant-pressure vessel to be screwed. Or grooves and projections are formed and fastened by fitting.

In addition to the threaded engagement and groove-to-projection engagement described previously, various engagement means may be employed, which are equivalent to combining the two configurations.

(Examples 1-8) The static pressure feeder of the present invention includes the pressure removal tool 111 formed through the side surface of the static pressure vessel in Embodiment 1-1.

When the amount of the fluid in the receiving space exceeds a certain amount during the process of filling the fluid in the receiving space, the fluid should be stably discharged to the outside. To this end, a pressure relief valve is formed on the side of the static pressure vessel. A pressure relief port is formed on the top of the static pressure vessel, and the pressure block passes over the static pressure vessel section, and when the receiving space reaches the pressure relief port, the fluid in the air port space is discharged to the pressure relief port. Therefore, the charging amount of the accommodation space can be forcibly controlled.

(Examples 1-9) The static pressure feeder of the present invention includes the warning horn 112, which is coupled to the pressure relief port, in Examples 1-8.

When the fluid in the accommodation space is a gas, noise is generated by the warning horn mounted on the pressure relief port when the gas leaks into the pressure relief port. This can infer that the user is over-stressed by sound.

(Example 2-1) In the static pressure supply device of the present invention, the static pressure container and the first connection pipe are formed in plural, and the chamber 410, to which the plurality of first connection pipes are coupled, And a first connection pipe (331b) for connecting the chamber and the first coupling hole.

If the diameter of the static pressure vessel is large, a large amount of fluid can be accommodated. However, if the diameter of the static pressure vessel is increased, the outer diameter of the press block must be increased, and the diameter of the O-ring coupled to the press block must be increased.

There is a limit to the accuracy of the inner diameter machining of a cylinder having a large diameter. Also, the sealing effect of large-diameter O-rings is not high. That is, a problem of productivity may arise. In order to prevent this, the inside diameter of the static pressure vessel of the static pressure feeder is formed with a small diameter. There are limits to the capacity of small diameter static vessels. Therefore, a plurality of static pressure vessels are used for increasing the capacity. A plurality of static pressure vessels shall be operated at the same pressure. A plurality of static pressure vessels are used to form the same pressure. Each of the static pressure vessels is formed with a first connection pipe. The first connection tubes communicate with one chamber. Thus, the chamber and the plurality of static pressure vessels can maintain the same internal pressure. The first connection of the first valve is engaged with the chamber.

(Embodiment 2-2) The static pressure supply device of the present invention includes, in Embodiment 2-1, a carrier 420 that receives the static pressure vessel, the first valve, and the chamber.

The plurality of static pressure vessels and chambers form a substantial space and are of a weight. Also, if the pressure supply is fixed, the static pressure vessel must be moved. To secure a massive static pressure vessel and mobility, the carrier houses a plurality of static pressure vessels, a chamber and a first valve. The plurality of static pressure vessels and the chambers are formed in one case or integrated into one band.

(Embodiment 2-3) The static pressure supply device of the present invention includes, in Embodiment 2-2, a horizontal support 430 mounted on the carrier and formed in plural.

To ensure carrier mobility, a castor is mounted on the bottom of the carrier. Brakes are mounted to selectively move and secure the casters. The movement of the caster can be selected by operating the brake. The carrier is kept horizontal with the ground. If the level is not maintained, the moving block is eccentrically moved, so that fluid outflow occurs. To prevent this, install a horizontal support on the carrier.

The horizontal supports form three supports and height adjustment screws. The three supports are fixed to the ground, and the height adjustment screws can be leveled.

(Embodiment 2-4) The static pressure supply device of the present invention includes, in Embodiment 2-3, a leveling system 440 mounted on the carrier.

To measure the level of the carrier, the carrier is equipped with a leveling system. Adjust the height adjustment screw mounted on the carrier horizontal support and judge the horizontal level of the leveling system. Since the 2-axis leveling system is used for the leveling system, it is possible to adjust the vertical and horizontal levels around the ground.

 (Example 3-1) A fluid supply device using the static pressure supply device of the present invention includes a body part 710 which houses therein a fluid supply pipe 701 and accommodates the main valve 702 for controlling fluid supply pipe opening and closing; A control unit 720 for controlling the opening and closing of the main valve, and a second connection pipe 332 for communicating the fluid supply pipe 701 with the second coupling member 312 of the static pressure supply devices, .

When a certain pressure is applied to the pressure supply device P to which the pressure is charged, the fluid enters the pressure supply device from the fluid supply device after the fluid supply device is coupled. The present invention is a constitution in which the body part is combined with a fluid supply device, and the body part forms a fluid supply pipe. The fluid supply pipe has a second connection pipe on one side and a nozzle on the other side. The fluid supply pipe is formed with a main valve and opens and closes the fluid inlet of the fluid supply pipe. One side of the second connection pipe is coupled with the body portion, and the other side is coupled with the first valve.

The fluid supply device P is coupled to the body portion, the body portion is coupled to the second connection pipe, the second heat pipe is coupled to the first valve, the first valve is coupled to the first connection pipe, The tube is combined with a static pressure vessel.

When all the conduits are in the open state, the static pressure vessel and the fluid supply device are moved until the same pressure is formed. However, if the pressure of the static pressure vessel and the fluid supply device are the same, no fluid movement occurs. Therefore, the pressure is supplied by the pressure supply device and the pressure balance by the set pressure of the static pressure vessel.

The static pressure vessel is formed in a cylinder shape, and the pressure is given by the weight of the pressure block. That is, it acts as a Pascal principle. The diameter of the static pressure vessel is fixed and the pressure is calculated by weight / area by the weight of the pressure block. That is, the fluid is supplied at the pressure set when the main valve is opened, and the fluid movement stops at the pressure balance. This can grasp the suspended state of the fluid flow from the stop of the pressurized block. Conventional devices measure the pressure supplied by measuring a pressure gauge. However, since the present invention supplies pressure from a preset pressure, the present invention has an advantage that even a person without technical knowledge can supply pressure.

(Example 3-2) The fluid supply device using the static pressure supply device of the present invention is the same as the fluid supply device using the static pressure supply device according to the practical example 3-1 except that both sides communicate with the pressure supply device P and the control part, And a pressure measuring pipe 730 for transmitting the pressure of the pressure supply device to the control unit 720 that actuates the pressure sensor 720.

In the case of Example 3-1, the condition of the fluid in the constant-pressure vessel is not considered. In the case of the gas, in Example 3-1, no problem occurs, but in the case of a fluid such as oil, an error occurs in which the self weight of the oil is not taken into consideration. Therefore, in the case of fluid such as oil, the pressure to be supplied must be measured.

In Example 3-2, a fluid supply pipe and a separate pressure measurement pipe are formed in the body part nozzle. The fluid supply pipe is for supplying fluid to the pressure supply device, and the fluid measurement pipe is for measuring the pressure of the pressure supply device. That is, the pressure generated by the supplied fluid is measured through a separate channel. The fluid introduced into the pressure measuring tube measures the pressure in the control part and blocks the main valve according to the measured signal.

The invention of Embodiment 3-4 interlocks the fluid pressure entering the pressure measuring pipe with the relief valve. The relief valve does not operate before a certain pressure, but the relief valve operates at a certain pressure. When the relief valve operates, fluid is ejected, and the ejected fluid is again connected to the rotary cylinder. Therefore, the rotary cylinder is rotated, and the rotary cylinder is engaged with the main valve to shut off the main valve. This has the effect that it can be operated without a separate electronic device, and the pressure setting can be precisely realized by adjusting the opening / closing pressure of the relief valve.

(Embodiment 3-5) In Embodiment 3-2, the fluid supply device using the static pressure supply device of the present invention is characterized in that the control portion includes a relief valve 761 in which the charging port is connected to the pressure measurement pipe 730, A pinion 764 rotatably engaged with the pinion gear, a pinion 764 rotatably coupled with the pinion gear, a pinion 764 coupled to the pinion, .

Embodiment 3-5 The control part of the invention transfers the pressure of the pressure measuring pipe to the relief valve. The relief valve does not operate to the set pressure, but operates when the set pressure is reached. When the set pressure is reached, fluid is ejected and the ejected fluid is supplied to the linear cylinder. The linear cylinder forms a radial tooth on the rod, and the radial tooth rotates the pinion. The pinion is connected to the main valve and rotates the main valve. Therefore, there is an effect that the main valve can be shut off by using the internal pressure of the pressure supply device.

When the set pressure is reached, fluid is ejected and the ejected fluid is supplied to the linear cylinder. The rod of the linear cylinder actuates the link and rotates the main valve by the rotational movement of the link. Therefore, there is an effect that the main valve can be shut off by using the internal pressure of the pressure supply device.

Embodiment 3-7 The control part of the invention operates the linear cylinder with the pressure of the pressure measuring pipe. The pressure inside the linear cylinder acts on the piston. The force acting on the piston is converted into a compression load on the spring, and the deflection according to the load changes depending on the shape of the spring and the material condition. That is, the rod displacement value of the linear cylinder is changed in accordance with the pressure of the fluid supplied to the linear cylinder. The displacement of the rod rotates the main valve through the conversion means. The converting means corresponds to a mechanical structure for converting a normal linear motion into a rotational motion, and preferably includes a rack and a pinion, and a link drive.
