Description

Technical Field

[0001] The utility model relates to the technical field of combined large-displacement steam traps, and specifically relates to a combined large-displacement steam trap. Background Technique

[0002] The combined large-displacement steam trap is a device specially designed to effectively drain the condensate in the steam system while preventing steam leakage. This kind of steam trap usually has a large displacement and can meet the discharge requirements of large-flow condensate.

[0003] In the prior art, most of the combined large-displacement steam traps are connected to the condensate pipeline through flanges and bolts to quickly drain the condensate in the steam system and automatically prevent steam leakage to the greatest extent.

[0004] However, in the prior art, the combined large-displacement steam trap is connected to the condensate pipeline through a flange. Tools are needed to install multiple bolts on the flanges of the steam trap and the condensate pipeline to fix the connection between the steam trap and the condensate pipeline. It is necessary to repeatedly screw multiple bolts with workpieces, which is very cumbersome and seriously affects the installation efficiency of the combined large-displacement steam trap. Content of the Utility Model

[0005] The purpose of the utility model is to provide a combined large-displacement steam trap to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: a steam trap body, with flanges connected to both sides of the steam trap body. A support ring is arranged at the rear end of the flange. Multiple groups of first springs are arranged around the outside of the support ring. Two groups of clamping rings are connected to the outside of the first springs. The two groups of clamping rings are respectively located at the upper and lower ends of the flange; and a first fixing block, with a plug-in block arranged at the bottom of the first fixing block. A fixing groove is opened in the middle of the plug-in block. A slot is opened at the top of the second fixing block. A telescopic groove is opened outside the slot. Multiple groups of second springs are arranged outside the telescopic groove. A fixed plug is connected to the inside of the second spring.

[0007] Preferably, the outside of the clamping ring surrounds the flange. There is a distance equal to the thickness of a flange between the outside of the clamping ring and the flange. The flange of the condensate pipeline can be inserted into the two groups of clamping rings.

[0008] Preferably, annular grooves are opened around the inside of the flange. Insert rings are arranged on the inside of the clamping rings. The insert rings can be inserted into the annular grooves to fix the clamping rings on the flange and prevent the clamping rings from swinging left and right on the flange.

[0009] Preferably, on both sides of the clamping ring located at the upper end of the flange, there are first fixing blocks, and on both sides of the clamping ring located at the lower end of the flange, there are second fixing blocks. The plugging block at the bottom of the first fixing block can be plugged into the slot opened at the top of the second fixing block.

[0010] Preferably, a sealing gasket is arranged in the middle of the inner side of the clamping ring, and the sealing gasket can seal the joint between the hydrophobic valve flange and the condensate pipeline.

[0011] Preferably, a connecting block is connected to the middle of the outer side of the fixed plugging block. The connecting block extends out from the inside of the second fixing block. Pulling the connecting block outwards can make the fixed plugging block disengage from the fixed slot.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] For a combined large-displacement hydrophobic valve proposed by the present utility model, first pull the connecting block to drive the fixed plugging block to contract towards the outside of the telescopic slot, so that the fixed plugging block disengages from the fixed slot opened in the middle of the plugging block, canceling the fixation of the plugging block. Then pull the two clamping rings outwards, align the flanges on both sides of the hydrophobic valve body with the flanges of the condensate pipeline, and then release the pulled clamping rings. The first spring connected to the rear end of the clamping ring pulls the clamping ring to contract through the contraction force, clamping the connection between the flange and the condensate flange. At the same time, the insertion ring inside the clamping ring is inserted into the ring groove opened on the outside of the flange to limit the clamping ring to prevent it from swinging left and right. When the clamping ring contracts to clamp the connection between the flange and the condensate flange, pull the connecting block again to drive the fixed plugging block to contract into the telescopic slot. At this time, the plugging block at the bottom of the first fixing block on both sides of the upper clamping ring is plugged into the slot opened at the top of the second fixing block on both sides of the bottom clamping ring. Then release the pulled connecting block, and the second spring in the telescopic slot pops the fixed plugging block into the fixed slot opened in the middle of the plugging block through the tension, fixing the plugging block in the slot and fixing the expansion and contraction of the two clamping rings, so that the clamping ring firmly clamps the connection between the flange and the condensate flange.
