Abstract

In factories dealing with fluid materials (various factories, nuclear power plants, etc.), various piping materials are connected vertically and horizontally, and valves and devices installed therein are numerously connected. Among them, valves are worn out frequently and must be replaced frequently. Replacement work replaces old or broken spots in unexpected places, and stopping the flow of fluid material can cause the entire line of the plant to shut down. It is often necessary to cut off both ends and replace with new ones. The present invention provides an enormous time for stopping a conventional valve by replacing the valve if the valve (which includes lamps, etc.), which is a problem in a factory handling such a fluid material, can be quickly replaced in a short time. In order to prevent the loss of oil and various losses, it will bring a profit to the production.The flanges of the left and right pipes, which are connected to the flanges on the left and right ends of the valve, are tapered so that the valves can be easily pulled out to the upper side or the side. The connection device is developed to be able to remove the conventional closed end.

Fluid material, valves.

According to the present invention, when installing a valve or the like in a fluid pipe, the pipe is cut and attached to the both ends of the flange at right angles to each other. It is inserted and bolted, so the packings may be stretched or corroded to remove the valves for long periods of time, so these flanges are not separated. Innovative new methods of replacing valves, etc., have been desired in factories that use fluids, such as the use of fluids.

The present invention is to develop a method and an apparatus capable of replacing a valve or the like installed in the pipe in a very short time as a technical problem.

A.Configuration

下俠)의 테이퍼(TAPER)형으로 부착하고 좌우 파이프 내단에 부착하는 프랜지도 이와 부합(符合)하는 각도의 테이퍼형으로 부착하여 밸브등을 끼워 넣어 연결하기 쉽고, 빼내기도 용이하게 하는 기본 기술 사상과 그 장치를 제1, 제2, 제3의 실시예 별로 상술한다.In the description of the configuration of the present invention, the left and right flanges attached to both ends of the valve and the like are shown in the upper and lower straits.

The basic technology that attaches in the taper shape of the lower part and attaches the flange to the inner end of the left and right pipes is tapered at the matching angle so that valves can be inserted and connected easily. And the apparatus will be described in detail for each of the first, second and third embodiments.

First embodiment

In Fig. 1, the flange 6 attaches the right flange 2 and the left flange 3 to the left and right ends of the valve 1 in the form of a tapered upper and lower narrow, and is attached to the inner ends of the left and right pipes 4 and 5 ( 7) the inner surface thereof is fixed in a tapered shape at an angle that perfectly matches the outer surface of the left and right flanges 2 and 3 of the valve 1, so that the lower end 6 'of the flanges 6 and 7 as shown in FIG. 7 ') to the right and left mouthpieces 8' and 8 "of the bottom plate 8 with bolts 8" 'and 8 "" and flanges 2, 3 and 6 and 7 As shown in FIG. 1, the bolts 6 'and 7' are fastened as shown in FIG. 1, and the boss 9 is downwardly protruded from the bottom of the valve 1, and a vertical downward spiral hole is drilled therein. At the center of the 8), align the central through hole 10 corresponding thereto, insert the washer 12 into the bolt 11, and upwardly insert the washer into the central through hole 10 and insert the washer 13 thereon. Thread the nut (14) and fix it to the bolt (11) with a pin (15) The tip of the bolt 11 with the washer 16 inserted was screwed into the downward spiral hole in the boss 9.

Second embodiment

In this embodiment, the valve replacement device constructed in the first embodiment is installed in a horizontally laid position so that the valve can be removed horizontally from the front.

In FIG. 5, the right and left flanges 18 and 19 of the valve 17 are attached in a tapered shape with a wide front and a narrow back, and the flanges 22 and 23 inside the left and right pipes 20 and 21 are formed of the valve flange. Attached in a tapered shape at an angle corresponding to the outer surface, the lower ends of these flanges 22, 23 are extended downward to form left and right heel 24, 25 and left and right on the upper surface of the bottom plate 26 connecting the lower inner surface. Protruding the dolce 27 (28) and the guide rollers (29, 30) on the upper surface of the valve 17 is provided with a track for exclusive use of the valve 17 that can smoothly retract horizontally to the front and rear will be.

Third embodiment

In this embodiment, the left and right flanges 32 and 33 of the valve 31 are attached at right angles to both ends of the valve 31, and the flanges 34 (35) at the inner ends of the left and right pipes are also attached to the pipe at right angles. The valve 31 is actuated by dropping the space by using various tapered packing materials.

That is, as shown in Fig. 8, the outer surface of the left and right flanges 32 and 33 of the valve 31 is thick and the lower side of the packing 32 '(33') is thinner so that the outer surface of the left and right flanges 32 and 33 is in the upper and lower sides. Tapered shape and thinner and thicker packings 34 and 35 are installed on the inner surface of the flanges 34 and 35 at the inner ends of the pipes so that the inner spaces are vertically narrowed to the left and right flanges of the valve 31. It is easy to insert and remove the valve by matching the packing 32 'and 33' with the tapered angle that is adhesively installed in the upper and lower narrow sides, and the left and right ends of the supporting plate 36 at the lower end of the flange 34 (35) by mouth. The configuration of connecting and elevating the valve 31 to the tip of the bolt 37 according to the first embodiment.

B. Operation

In the case of configuring the valve replacement device as shown in FIG. 1, to remove the valve 1, first, loosen the bolts 6 ′ and 7 ′ and connect the flanges 2 and 3 with the flanges 6 and 7. When the nut is rotated to the left with the spar, the valve 1 acts to push up the boss 9 strongly in the state that it is in the spiral hole in the boss 9 at the tip of the bolt 11, so that the valve 1 is as shown in FIG. It rises upward and its strength is so strong that it wins the adhesive force between the inner surface of the flanges 6 and 7 and the outer surface of the flange 2 and the outer surface of the flanges 2 and 3. It is easy to be put out and when assembling the valve 1 into the position as shown in FIG. Since the spiral of the tip of the bolt 11 is gradually deepened into the spiral hole of the boss 9, the bar A bolt 11 having a rear end hanging on the floor plate 8 serves to pull down the boss 9.

The drop fitting to a predetermined position and the flange (2) (6), the flange (3) (7) by tightening the bolts (6) (7), respectively, bringing the effect of significantly shortening the valve replacement time.

As shown in FIG. 5, the apparatus of the first embodiment is laid horizontally, and the guide rollers 27 and 28 of two rows are installed to install the track to advance and retract the valve horizontally. Turn left) and bolt 11 pushes boss 9 to the side. At this time, valve 29 moves smoothly through guide rollers 29 and 30 and approaches boss 9 to assemble the helix. Put the pipe 11 at the tip of the bolt 11 and turn the nut 14 to the right, so the bolt 11 pulls the valve 17. Therefore, the bolt 11 can be pulled to a predetermined position to quickly replace the valve to be fastened with the bolts on the left and right sides. .

Packings 34 'and 35' attaching the outer surfaces of the packings 32 'and 33' to the tapered shape of the upper and lower straits in the space attached to the right angle and avoiding the tapered configuration of the flanges as shown in FIG. The outer surface of the upper and lower side can be configured to slide out and the nut 38, the bolt 37 can be rotated left and right to quickly replace the valve.

If the valve replacement device is installed according to the present invention, the work can be completed in a very short time at the time of replacement, and thus the downtime of the work line can be shortened to a minimum, and thus the productivity increase effect can be sufficiently compensated.
