KR20040110953A - Anti-freezing pipeline attached mechanism for preventing the freezing without discharging water of pipelines in midwinter - Google Patents

Abstract

PURPOSE: An anti-freezing pipeline attached mechanism is provided to prevent the freezing without discharging water from a water pump, a heating pipeline and a pipeline for connecting with a cooling spring cooler, etc. in winter or vacation time, to promote work efficiency by reducing the time required for discharging and filling water and to have the effect on safety by protecting high-priced components, equipment, etc. CONSTITUTION: A pipeline is installed through the steps of perforating many holes(2) on a pipe(1) installed to a part which is exposed to the outside or easy to be frozen, fixing a nut connection(4) having fastening threads(3) to the hole(2) by a welding unit(5) and installing an anti-freezing attached mechanism(6) to the nut connection(4) at regular intervals. The anti-freezing attached mechanism(6) comprises the steps of fastening a case(7) and a cap(11), forming fastening threads(13,14) on the upper and lower ends of the case(7), inserting a lifting stopper(8) fixed with rubber O-rings(10,10') to retreated grooves(9,9') in the case(7), then installing a spring(15) to bear the appointed pressure, fastening a cap(11) having a fastening thread(12) with a fastening thread(13) of the case(7), and fastening a fastening thread(14) of a case(7) to a nut connection(4) of a pipe(1). If the water in the pipe(1) froze, the lifting stopper(8) of the anti-freezing attached mechanism(6) lifts up to form a space which houses and regulates the increased volume caused by frozen pipe to prevent the weak part of the pipe(1) or a water pump from freezing to house and adjust the expanded volume.

Description

Freezing Piping Attachment {omitted}

TECHNICAL FIELD The present invention relates to a freeze protection pipe attachment device, and in particular, a pipe pipe, a connection part, a connection device, etc. in a cold winter season, without draining water contained in a pipe pipe used for connection to a water pump, a heating system, or a cooling sprinkler. It relates to a freeze protection pipe attachment to prevent the freeze.

Conventionally, during a cold winter season or a vacation period, water contained in a pipe connected between a water pump and a heating system or a sprinkler freezes to prevent freezing of various piping devices or pipes, and the water is returned again during operation. Because we have to repeat the process of filling Very inconvenient to use, long working time, there was a problem that must consume a lot of water.

If the water was not drained, weak pipes, critical connections and water pumps would freeze, resulting in more maintenance time, cost and inconvenience.

The present invention has been created to solve the above problems,

Its purpose is to prevent freezing of water pumps, heating pipes, and cooling sprinkler connecting pipes during cold winter seasons or vacations without repelling them, and to avoid refilling water during operation.

In order to achieve this purpose, a space for accommodating and adjusting the water should be formed even if the water in the piping pipe 1 freezes and expands in volume. The freeze protection accessory 6 is provided with a lifting stopper and a spring that can withstand a certain pressure in the case to which the cap is fastened. The space is formed by pushing the lifting stopper, so that the volume can be accommodated and adjusted.

In the installation of piping pipes,

Holes 2 are drilled in a number of places of the piping pipe 1 installed in places exposed to outside or freeze, and a nut connection 4 having a fastening thread 3 formed therein is formed on the welds 5. Etc., and the nut connection part 4 is fastened and installed at the nut connection part 6, and is installed while maintaining a constant interval (approximately installed at intervals of about 1 m when the pipe diameter is 20 mm). The device 6 is formed by separating the case 7 and the cap 11 to be fastened and assembled, and the case 7 is provided with fastening mounts 13 and 14 formed on the upper and lower end sides, and the case 7. An elevating stopper 8 having rubber o-rings 10 and 10 'mounted therein is inserted into the recess 9, 9', and a spring 15 capable of withstanding a constant pressure is inserted therein. On the upper side, the cap 11 having the fastening 12 formed on the inner side is fastened to the upper fastening side 13 of the case 7 and the lower end of the case 7 is fastened. 14 is formed to be fastened and assembled to the nut connection portion 4 of the piping pipe (1), so that the water in the piping pipe (1) freezes, when the volume increases, the lifting stopper (8) of the freeze protection accessory (6) It is an accessory for preventing the freezing of wind, forming a space while raising and lowering, and allowing the volume to be accommodated and adjusted so as to prevent freezing of the weak spot of the piping pipe 1 or the water pump 20 and the like.

The operation of the present invention configured as described above is as follows.

When the water is not frozen as shown in Fig. 3, the spring 15 of the case 7 pushes the lifting stopper 8 on which the rubber o-rings 10 and 10 'are mounted so as to withstand a constant pressure. Space will be created or water will not enter.

However, when the water is frozen as shown in Figure 4, it is usually necessary to increase the volume of the water by 1.1 times, and this space is required so that the weak spot of the pipe 1 or the water pump 20, etc. are not damaged. Therefore, as the water freezes as shown in FIG. 4, the volume increases, pushing the lifting stopper 8 of the freezing attachment device 6, and at this time, since a certain pressure or more occurs, the spring 15 is hardened and thus a necessary space is formed. The frozen water is introduced into the weak pipe of the pipe 1 or the water pump 3, and the like does not damage and freezes.

As described above, the configuration of the present invention is simple, easy to use, can reduce the cost by reducing a lot of sewage, reduce the work time and replenishment work time to reduce the work efficiency, installation is easy It is a very useful invention with a safe effect that can protect difficult and expensive parts and devices.
