Description

expansion strainer {A expansion strainer}

The present invention relates to a telescopic strainer, and more specifically, it is very easy to replace a large meter, so it can solve the chronic problems that occur during replacement, and can filter foreign substances contained in tap water supplied from a water supply source, It relates to a telescopic strainer capable of rapidly discharging foreign substances to the outside.

In general, a water meter is installed in the middle of a pipe that supplies tap water from a water source to measure the amount of tap water supplied to multiple facilities and buildings.

When the pipe and the water meter are directly connected and installed, the tap water moves in a mixed state while moving through the pipe, and the water meter malfunctions frequently due to this foreign material. A strainer having a sieve member inside is installed so that tap water can be supplied to multiple facilities and buildings.

As prior art of the strainer, there are Republic of Korea Patent Publication No. 10-0485303 and Republic of Korea Patent Publication No. 10-0787838, and a sieve member is separately coupled and installed to enable separation and replacement in the internal installation space of the main body as a configuration, The sieve member is manufactured by firmly installing a sieve on the upper and lower fixing members, and as a coupling part with the main body, airtight maintenance members are installed on both sides to maintain airtightness between the inlet and the outlet with the sieve as the center of the sieve member. A step is formed inside the central flange portion of the main body and a packing is inserted into the step as an upper portion of an upper fixing member having a handle on the upper portion, and the finishing member is fastened and fixed from the upper portion, and one side of the body is the end The opposing coupling part is integrally configured to have a flange part in the other side coupling part longer than the other side coupling part, and the meter is directly coupled to the opposing coupling part so that it can be used.

The strainer of the prior art has to replace the water meter coupled to the opposing coupling part every 6 years, but the counter coupling part and the meter are in close contact for a long time, making it difficult to separate and difficult to assemble.

And, when the strainer is blocked by foreign substances, the finishing member is separated from the main body in a state in which tap water flowing at high pressure is cut off, and then the strainer is drawn out to remove the foreign material, and the state of the strainer member again After checking, it is necessary to replace it or install it again in the internal installation space of the main body, which increases the working time and cost, and there is a problem that the work is cumbersome and difficult.

A rubber packing 340 is configured to provide a sealing force between the upper fixing plate 320 and the closing cover 170 .

One or several discharge holes 331 are formed in the lower fixing plate 330 to match the shape of the sieve 310 so that foreign substances A deposited on the sieve 310 toward the ball valve 150 can be discharged. .

7 is a view showing the configuration of a ball valve,

The configuration of the ball valve 150 is to form a discharge regulator 151 in the shape of a sector in front of the ball valve 150 as in Korean Patent No. 10-2053423 so that a person other than an administrator cannot arbitrarily operate it. Therefore, a detailed description of the configuration will be omitted in the present invention.

That is, the ball valve 150 cannot rotate the discharge control body 151 without using the dedicated lever 500 because the discharge control body 151 has a sectoral shape, and cannot be arbitrarily operated by a person other than the manager. it is a structure

8 is a view showing another embodiment of the telescoping strainer,

The telescopic strainer 100 configured to drain foreign substances and tap water to the lower part by configuring the ball valve 150 in the lower part of the body 110 is easy to install on the ceiling, but when installed on the floor, the ball valve 150 There is a disadvantage that the installation space has to be formed widely because the outlet part of the outlet part must be installed so that it does not touch the floor, and the existing strainer installed so that the lower part of the body 110 touches the floor is installed in the configuration of the ball valve 150 configured in the present invention. Since there is not enough space to replace the work, to compensate for this, the ball valve 150 is coupled to the lower part of the main body 110 as in another embodiment of the present invention and the elbow 154 is further configured to be rotated. .

The body 110 is formed with a nut hole 111 so that the socket 152 can be screwed to the lower bottom to install the ball valve 150 .

The socket 152 has a bolt portion 152a formed at the front, and a locking frame 152b formed at the rear side.

The locking frame (152b) is configured with a nut 153 at the front, and an elbow 154 screwed with the nut 153 at the rear.

The nut 153 is axially rotated at the center of the socket 152 to position the ball valve 150 in a direction desired by the user, and to be caught by inserting the locking frame 152b of the socket 152 inside. To form a locking jaw (153).

Between the nut 153 and the elbow 154, a leak-proof packing 155 is configured to be sealed so that water leakage does not occur.

When the ball valve 150 is screwed to the end of the elbow 154, another embodiment of the present invention is completed.

The telescopic strainer 100 configured in this way is fixed by loosening the bolt 400 fastened to the coupling 220 of the connecting means 200 when replacing the old water meter 10 or the fixed water meter 10 The coupling 220 is separated from the flange 210, and at the same time, the sealing force of the packing 230 between the fixed flange 210 and the coupling 220 is released, and the expansion and contraction pipe 160 is connected to the fixed pipe 130 ) side, the expansion and contraction pipe 160 is separated from the water meter 10, so that the water meter 10 can be replaced conveniently and quickly.

And the present invention is a dedicated lever 500 in which the administrator keeps the ball valve 150 installed at the bottom without the operation of removing the closing cover 170 when foreign substances A are deposited on the sieve member 300 installed inside. ) to provide the convenience of use that can quickly discharge foreign substances (A) deposited on the sieve member 300 to the outside.

In addition, the present invention can be installed in a narrow installation space by further configuring the elbow 154 so that the ball valve 150 can be installed in the lower part of the body 110, and can be replaced with an existing strainer.

And in the present invention, the ball valve 150 can be axially rotated at the center of the socket 152 so that the user can position the ball valve 150 in a desired direction.

The above is merely a preferred embodiment formed as an improvement of the present invention, and is not intended to limit the present invention by any means. should be included within the scope of protection.
