Examples

Referring to fig. 1, the present invention provides a valve station 10 that can be connected to a pipe of a heating apparatus including the pipe and the valve station 10 only through a first connection 11 and a second connection 12. The valve station 10 of the present invention includes a first connection part 11 and a second connection part 12, and a first stop valve 30, a second stop valve 40, a filter 60, a drain valve 80, and a check valve 20 are integrated on the body of the valve station between the first connection part 11 and the second connection part 12. The first connection 11 and the second connection 12 are used for connecting pipes of a heating device.

Therefore, when the valve station 10 of the present invention is connected to a pipe of a heating apparatus, only the first connection portion 11 and the second connection portion 12 need to be connected to the pipe, thereby solving the problem of inconvenient installation of the valve station 10.

As shown in fig. 1, the valve station 10 is a tubular body, and a first connecting portion 11 and a second connecting portion 12 are disposed on both sides of the valve station 10, wherein the first connecting portion 11 is a medium inlet end, and the second connecting portion 12 is a condensed water outlet end. The first stop valve 30 is provided near the first connection portion 11, the second stop valve 40 is provided near the second connection portion 12, and the trap 80 and the filter 60 are provided between the first stop valve 30 and the second stop valve 40. The output end of the trap 80 after being drained is provided with a filter 60 for filtering contaminants in the condensed water. At the inlet end of the trap 80, a check valve 20 is provided, the check valve 20 being disposed in the interior of the tubular valve station 10, the check valve 20 being disposed such that condensate passing through the trap 80 does not flow back.

Further, a blowdown relief valve 70 is communicated with the end of the filter 60, and the blowdown relief valve 70 can lead out the dirt filtered by the filter 60. When the dirt needs to be discharged, the first stop valve 30 and the second stop valve 40 are closed, then the blowdown relief valve 70 is opened, the first stop valve 30 is opened, the filter screen of the filter 60 can be flushed without any erosion by the muddy water shocking of the steam and the condensed water, and the accumulated dirt is discharged.

Specifically, the drain valve 80 includes a drain structure 81, and the drain structure 81 is fixedly connected to the valve station 10 by bolts, wherein the number of the connected bolts is not limited, and in the present embodiment, the number of the bolts is two. When the hydrophobic structure 81 needs to be replaced, the first stop valve 30 and the second stop valve 40 are closed, the blowdown relief valve 70 is opened, the pressure in the valve station is relieved, and the hydrophobic structure can be replaced quickly.

As shown in FIG. 3, trap 80 is a Venturi trap with a venturi tube disposed within a hydrophobic structure 81, wherein the bore of the venturi tube is selected according to the steam pressure and the volume of water to be removed, such that the Venturi valve is adaptable to heating devices of different steam pressures and different volumes of water to be removed.

An emergency drain valve 50 and a test valve 90 are also integrated on the valve station 10. When it is desired to test the state of trap 80, the state of trap 80 can be detected through the outlet of test valve 90 by closing first stop valve 30 and second stop valve 40, opening test valve 90, and opening first stop valve 30. When the water outlet pipe connected with the second connecting part 12 is blocked or repaired, the emergency water discharge valve 50 is opened to discharge the condensed water after water drainage.

Specifically, all the valve bodies in the utility model are supported by stainless steel, and specifically, the valve bodies in the utility model are supported by medium-temperature candle stainless steel, so that the valve bodies are corrosion-resistant and scouring-resistant, and the service life of the valve bodies is prolonged.

It should be understood that the technical solutions and the inventive concepts according to the present invention may be equally replaced or changed by those skilled in the art, and all such changes or substitutions should fall within the protection scope of the present invention.
