Description

The automatic control float operated valve for the un-limited high & lower liquid level}

TECHNICAL FIELD The present invention relates to a float-operated unlimited high and low level control system-automated valve. It is created by buoyancy and can control unlimited high and low level intervals by single operation float, and it is used for automatic level control system in open or pressurized closed tanks handling various liquids (especially high temperature, corrosive, high flammability). The present invention relates to a float-operated unlimited high and low water level control system that can be applied to large diameters and high pressures, and to tanks that are swinging.

In the conventional float valve, it is natural that the disc of the valve must press down the valve seat to reliably prevent the leakage, but the existing patent (Korean Patent No. 181762), which is a pre-invention, obtained by the pressure drop. Some of the higher pressures) are those of Patent 3, which are not applicable to large diameters and high pressures due to their structural characteristics. An invention was achieved that could solve both performance and defects.

The present invention not only solves the shortcomings described above, but also has been created for the purpose of pioneering higher-order use, and lists the problems and improvements that are problems in the existing float-operated valve.

Challenge 1: Constraints in the formation of toilet seat pressure to prevent leakage.

Challenge 2: Constraints on greater valves and greater pressure.

Challenge 3: Constraints on the maximum buoyancy composition of the float due to the pressure resistance constraints of the spring-spring.

Task 4: Simplify existing valves and invent a fussing-spring device.

Task 5: The necessity of the method of transmitting the precise current water level signal of unlimited long and short intervals without the electric source and the unique structure and function of the equipment.

[Solution of technical problem to be achieved]

In the existing mechanism configuration in which the spring-spring for forming the toilet seat pressure is formed in one body closely with the valve body, the valve and the working pressure of a larger diameter are used. There is a limit that cannot be developed due to constraints such as insufficient pressure of the toilet seat, which is required for heat and temperature. In other words, the bulky spring-spring device required for the desired large valve could not be configured in one body with the valve body.

In the construction method of the new mechanism for solving the constraint of the toilet seat pressure, which is the technical problem 1 described above, a footing-spring mechanism made of the shoe name as the maximum buoyancy forming device in the float is provided. The design principle has been established so that the constraints can be sufficiently and unlimitedly eliminated by a new configuration which is separated from the valve body and separated at a suitable distance as shown in FIG. 1. That is, if the comparative relationship between the force as FIG. 1 and FIG. 3, which is the patent of the present applicant, is replaced by "I" in FIG. 2 and "A" in FIG. 2, the footing-spring reaction force R1 is shown in FIG. Assuming that the interval of l2 is the same as that of the existing patent and the newly filed "B" in FIG. 2, the mechanical relationship is explained so that R1 acts with a force inversely proportional to the interval between l1 'of the likelihood and l1 of the left view. do. In other words, It is compared with the existing one. Therefore, if the existing and new have the same strength of spring-spring, the reaction force of the spring-loading spring of R1 will be able to exert a pressure force on the same toilet seat with a large force doubled in inverse proportion. Buoyancy can be considered in the same proportions in size and buoyancy. Therefore, according to this method, it is possible to solve all of the above-mentioned problems, the limitations 1, 2, 3, etc., so that the pressure can be applied to a sufficient seat even in a valve that is much larger than a conventional valve. As the design principle is established, in addition to the certainty of leak prevention and the improvement of the allowable pressure, the saturation temperature of the applied liquid corresponding to the improved pressure is also improved.

The configuration of the float-operated unlimited high and low level control system automation valve according to the embodiment of the present invention will be described in detail as follows. First, the float-operated unlimited high and low level control system automation valve according to the present invention is described. From the configuration disclosed in the Applicant's 1998 Patent No. 181762, "Float-operated high and low level automatic control valve," it greatly simplifies the complex body of the valve and eliminates various constraints incurred in manufacturing, as well as a large load. It is characterized in that the maximum limit of the valve due to pressure is maximized. This float-operated unlimited high and low level control system automation valve is formed on the upper end of the valve body 100, arm (Arm, 22) ) And the one side end through-hole of the arm 22 is slidably coupled, the tank bottom in a vertical downward (垂直 下 向) The rod (141) installed on the shaft of the longitudinal rod (縱軸 捧, 5) and the longitudinal rod (5), which is installed to the swing arm (140) inside the valve body (100) and By operation of the float 41, including an actuating float 8 which flows due to buoyancy according to the water level, and a non-gravitized float 41 containing water and air at a predetermined mixing ratio. In the valve for adjusting the water level, Bolted to one end of the arm 22, the axis of the longitudinal rod upper end portion 20 including a through hole in the center (縱軸 捧 上 上部 軸 受, 20), and the upper end of the longitudinal shaft rod It is coupled to the trigger pin 21 of the lower end of the bearing 20, the trigger blade (19) having a departure stop 12 in the lower portion, and the departure stop 12 of the trigger blade (19) Pushing spring outer cylinder 13 is provided with a protrusion (突起 部) (18) is formed on one side of the upper end is caught; A spring spring inner cylinder 16 and a spring spring inner cylinder 16 formed to be inserted into the inside of the spring spring outer cylinder 13 to be slid, and the spring spring inner cylinder 16 and the outer cylinder 13 are elastically provided. A spring for the inner cylinder eruption, which is provided in the pushing spring 15 for supporting and the upper end shaft bearing 20 of the longitudinal axis rod, for elastically supporting the outer upper end surface of the inner spring 16 of the spring spring. The configuration of such a spring spring is to increase the allowable limit of the valve to the load pressure of the existing small capacity, as well as the large capacity fluid storage tank. In addition, one side of the arm 22 is provided. It is fixed to the worm (Worm, 33), the worm wheel (Worm-wheel, 34) and the worm gear box (Worm-gear box, 30) containing the worm wheel shaft 35, and the worm of the worm gear box (30) A sprocket wheel 32 installed on the shaft leading to The link-chain 28, which is formed by suspending the weight 29 having a fixed weight on the other end, is fixed to the working float 8 via one wheel 32, and the other end is further fixed. This is applied to a known signal transmitter by applying the rotational force of the worm wheel shaft 35 in accordance with the rise and fall of the operating float (8) to convert the water level by forward and reverse rotation of the worm wheel shaft (35) analog and digital. A mechanical configuration that allows marking in a manner that prevents the risk of explosions and fires resulting from the tiny sparks inherent in electrical or electronic configurations indicating the level of water in tanks storing extremely flammable materials. And, sliding along the outer circumferential surface of the rod 141, the lever cross-coupling number (9) provided with a connecting shaft 10 on one side, and the connecting shaft 10 is hinged to one side The longitudinal rod It is preferable to connect the rod 141 and the longitudinal rod 5 by providing a cross longitudinal shaft 6 fixed to the shaft fixing bolt 7 at 5. An upper collar (25) to prevent separation of the longitudinal rod (5) and an outer cylinder collar (13-1) for pushing up the lower surface of the foot spring spring (13) when the water level rises; The upper and lower level set collars (Callar) 3 and the lower limit level set collars (Callar, 39) are fixed to the predetermined positions of the longitudinal rods 5 with set bolts 4 and 26. This is the operation float 8. Is to be able to flow smoothly between the upper limit level set collar 3 and the lower limit level set collar 39 along the outer peripheral surface of the longitudinal rod (5). In addition, the various collars (Callar, 25, 13-1, 3, 39) is to have a variety of polygonal shape, it will serve as a stop stop.

Looking at the organic operating relationship of the float-operated unlimited high and low level control system automation valve configuration as described above are as follows.

As the water level in the tank rises, the actuation-float 8 touches and holds the upper water level setting collar 3 fixed to the set bolt 4 at a predetermined position at the upper end thereof. The cross longitudinal axis number 6, which is fixed to the fixed bolts 7 by 5, rises, and the lever cross axis number 9 hinged to the cross axis 10 by the connecting shaft 10 is fixed. Sliding flows along the outer circumferential surface of the rod 141. Subsequently, when the actuating float 8 rises to a predetermined level, the outer cylinder push-up collar 13-1 causes the pressing spring outer cylinder 13 to pressurize. As the wing 19 of the trigger is extended to the outside by the rising of the footing spring outer cylinder 13, the compression of the footing spring 15 is caused. The footing spring is caused by the compression force of the footing spring 15. The inner cylinder 16 is pressurized and thus the inner The spring 17 for the extraction is compressed, and the upper surface of the inner spring 16 of the foot spring is caught by the jaw 14 of the wing 19 of the trigger that is being lifted, thereby suppressing the lift. The pressure of 15 increases gradually as the buoyancy rises in the actuating float 8. As a result, the tank is subjected to a compressive force until a predetermined " maximum buoyancy force " is established in the actuating float 8 by raising the level of the tank. At this point, the outer cylinder 13 of the footing spring is also raised along with the footing spring. When the protrusion 18 provided on the outer circumferential surface of the upper end of the outer cylinder 13 is opened by pressing the wing 19 of the trigger, the foot spring spring inner cylinder 16 is released from the jaw 14 of the wing 19 of the trigger being supported. The outer cylinder 13, the longitudinal rod 5 and the rod 141 at the same time cause a sharp rise at a slight spacing. This rise causes the hook-spring to stand by. The roller 124 is placed on the dynamic curved surface of the hook wedge, and the large force of the foot spring 15 is transmitted to the disc disc 101 of the valve as described above. (seat 102) has an unprecedented strong occlusion It will be used for.

When the water level is lowered, as shown in FIG. 3, the bottom surface of the actuating float 8, which is lowered along with the water level, presses the lower limit water level setting collar 39 downward, and the vertical rod 5 is downward. The swing arm 140 is rotated to push the hook lower end 132 to the end of the lower limit water level adjusting screw 144 that is inserted into the swing arm lower arm 147 and the mechanical dynamics of the hook wedge. The roller 124 and the lever 120 which were placed on the curved surface are dropped at the same time. At this time, since the disk 101 is spaced apart from the sheet 102, the fluid is supplied to the inside of the tank. In this way, the organic operation of the above components is repeatedly performed, and the tank The level in the water is automatically kept constant by the operation of the float.

Without limiting the electrical source of the above-mentioned technical problem 5, it is possible to precisely transmit the current level signal of unlimited long intervals from the upper limit to the lower limit in the tank so that it can be known in the field or in the control room. In conjunction with other systems, it is a current level signal transmission facility that can be used as a purely mechanical device in a tank to allow automatic control of the associated system. This is described as a pure mechanical example of the configuration and the action of adopting a combination of a worm-gear device and a link-chain 28.

As shown in Figs. 1 and 4, an example in which the link-chain 28 is attached to the actuating float 8 and is installed on the angle 22 by hooking the hook 27 at the corner of the actuated float is shown. Hook the sprocket-wheel sprocket (32) inserted into the worm shaft (33) of the box (gear-gear box 30) and at the other end attach a proper weight-weight (Tension-Weight 29). Suspend and extend the shaft 35 of the worm wheel 34 to the coil-spring 36 or other universal joints to act as a flexible-coupling 36. Thus, any conventional signal transmission device is allowed to penetrate through the three shafts outside the tank by inserting the sealing bushing 37 into the flange top of the valve or the tank wall plate. When connected to a device to transmit the current level signal, the pitch of each link-chain word As the worm wheel rotates accurately and repeatedly, the suspension level can be transmitted to the outside of the tank even at an unlimited depth in relation to the number of revolutions according to the depth. Can be used as a signal.

The invention patent (Korean Patent No. 181762), which I had acquired, was lost only for the reason it was disclosed before application, but this float-operated valve makes it possible to apply to larger valve diameters under high pressure and high temperature which was impossible with this patent. A fundamental new mechanism of construction of the system and the invention of the new fuxing-spring facility which makes it possible to implement it were also invented.

In other words, the reliable closing ability required for the valve is the most basic condition. To this end, it is necessary to rely on the pressing force by the disk on the toilet seat surface, which is the principle of construction within the dehydration limit of the pushing spring, which is a component close to the valve body in the floating valve of my previous patent. Thus the buoyancy of the working float is also to be established within that range. The effective buoyancy that is ultimately transmitted to the valve disc is that some of the maximum buoyancy thus obtained is used, and heavy fuming-spring devices cannot be applied to the valve body. There was no.

The above-mentioned type of spring-spring type in the existing patent valve is available in medium and small size valves, but in order to use for large diameters and high pressures, the push-spring device structure which is closely integrated with the valve body is impossible in many ways. Heavy structural limitations, elasticity constraints of the spring-spring, ultrahigh-pressure contact friction between the surface between the upper plate 223 and the lower plate 224, hand wear, excessive complexity, etc.) In view of this, the present patent application holds the seating-spring device in a remote position by isolating it from the main body, and by applying the invention of the newly-developed present pushing-spring device, the seat is sufficient for a large diameter and high pressure valve as described above. As a new membership was created to secure the pressure of the Section 3 can be solved all at once. Conventional float-valve has been limited to low pressure limited to medium and small diameter due to lack of pressure in the seat, the present invention solves such a problem to expand the constraint range of the large diameter, that is, the large diameter industry greatly. Pressure-resistant, heat-resistant, corrosion-resistance, impact resistance, flammable safety, applicability to rocking tanks, unlimited upper and lower limit 2-point water level control possibility, control system Almost all-purpose and almost maintenance-free structure with the possibility of sending out precise suspension level signal for automation etc. Float-operated unlimited high and low water level control which is economical as it can be made by a simple single valve installation It relates to the effectiveness of system-automated valves.
