Description

Drain valve having sight glass

The present invention relates to a drain valve having a sight glass, and more particularly, a drain valve connected to an alarm valve installed in a fire extinguishing system installed in a building is integrally formed with a test valve and at the same time therein is embedded a sight glass therein. It relates to a drain valve having a sight glass that can be seen.

In general, a fire extinguishing system is installed in a building to prepare for a fire, and a sprinkler system is known as being installed and used the most among such fire extinguishing facilities. When the sprinkler system is always filled with pressurized water at a predetermined pressure inside the pipe, and the thermal part of the sprinkler head is opened due to a fire, the pressurized water of the pipe is discharged and an oil / water detector is activated to generate an alarm. The device is driven so that the water is sprayed continuously through the sprinkler.

Conventionally, as shown in FIG. 1, a sprinkler installation for a general collective house is provided with several sprinkler heads 1 for each arc of each floor of the collective house, and in each arc, each head 1 is provided with a sprinkler pipe (1). ') Is connected to the secondary side of the running water detection device 3, and the digestion water pipe 2 is connected to the primary side of the running water detection device 3, and each pipe 2 is connected to the ground floor of the collective house. It is arrange | positioned and is connected to the water storage tank 6 through the pressurized water pump 4 and the pressure retention pump 5 in the strata. Moreover, the pressure tank 7 and the pressure switch 8 which can detect the pressure drop in the said piping 2 through the pressure tank 7 are connected to the said piping 2. In the drawing, reference numeral 9 is an auxiliary water tank of the digestive water disposed on the roof.

In the sprinkler installation, the entire pipe is filled with water during the boundary operation, and a positive pressure (0.1 MPa or more at the farthest point from the pressure pump 4) is applied by the pressure maintaining pump 5, and a house P In the event of a fire, the nozzle of the sprinkler head 1 ″ is automatically foamed by heat, and the extinguishing water filled in the pipe 1 'is discharged from the head 1 ″. In any house P, the reed switch of the water flow detection device 3 is turned on, and a fire alarm or the like occurs accordingly. In addition, the pressure switch 8 detects the drop in the pressure inside the tube based on the foaming of the head 1 ", and turns it on, and the pressurized water pump 4 is started based on this ion, and the water tank into the pipe 2 is turned on. The extinguishing water in (6) is pressurized and returned, and then the extinguishing water is waterproofed from the sprinkler head 1 "to perform extinguishing activity.

On the other hand, the installation of the conventional water flow detection device has a problem of freezing in the winter when installed in the generation balcony, there is a problem that it is difficult to change the installation location of the test device for testing the flow inspection device when the balcony expansion. In addition, since the running water detection device is installed inside each household, it is inconvenient for the worker to enter the generation where the running water detection device is installed to test the operation state. It was possible only, and there was a problem that can not be tested if all residents of the household went out.

In order to solve this problem, Utility Model Registration No. 20-0414294 filed 'Alarm Valve Drain Connector with Test Orifice and Transparent Checking Hole'.The test valve of the sprinkler facility was installed in the alarm valve chamber to install the sprinkler system. The test can be performed at any time at any time, so that the water discharged from the test valve can be checked directly with the naked eye during the test, and the main configuration will be described with reference to FIGS. 2 and 3. When the internal pressure of the branch pipe line 20 is greater than the set pressure in the direction of the discharge port on the side of the vehicle, a drain valve 30 for discharging water to the outside is provided, and the body 40 and the drain are discharged from the drain valve 30. It consists of a confirmation window 50 for visually checking the water discharged when the valve is opened, and an orifice 60 connecting the test valve output side and the body.

However, the body 40 is connected to the drain valve 30, and the confirmation window 50 must be separately assembled to the body 40, and the orifice connector 40a must be formed on one side of the body 40. There was a problem that the number is increased and the number of work.

That is, the body 40 to be combined with the drain valve 30 should be manufactured separately and combined, and a separate confirmation window coupling structure should be formed on the body, and the orifice connector 40a should be separately formed on the body 40. Therefore, the work maneuver is increased and the connection between the drain valve 30 and the body 40 has to be watertight, so there is a problem that workability is very poor.

The present invention has been made in order to solve the problems according to the prior art described above, the drain valve is connected to the alarm valve is installed, but the test valve is formed integrally with the test valve and installed inside the sight glass to observe the interior Its purpose is to provide a drain valve with a sight glass that can be utilized as a simple and monitoring window.

The drain valve having a sight glass according to the present invention is connected to an alarm valve for water flow detection, the drain valve flowing water, the drain valve is installed on the side of the drain valve for drainage at the connection portion of the alarm valve And, a test valve for draining the water of the bypass pipe connected from the sprinkler is installed on the upper side, the drain valve body is characterized in that the sight glass for observing the inside is installed.

Here, the sight glass is characterized in that it is installed back and forth to observe both before and after.

Further, the front and rear of the drain valve body is formed with a straight line, characterized in that the packing, the sight glass, and the bushings are assembled in order in the front and rear holes, respectively.

The drain valve having a sight glass according to the present invention has a built-in drain valve and test valve integrally, so that the construction is simple, the construction cost is saved, and the weight is light, and the handling is smooth.

In addition, the drain valve having a sight glass according to the present invention integrates a test valve and a sight glass function into the drain valve, and the piping configuration is simple. End-of-pipe installation of pipes in the valve drain line eliminates water damage from discharge.

In addition, the drain valve having a sight glass according to the present invention can check the presence or absence of the test pressure in the monitoring window attached to the front and back, can also be utilized in the secondary pressure retreat, the orifice inner diameter is the same as the inner diameter of the sprinkler head test valve It plays the same role as opening, and provides the effect without fear of freezing.
