Description

Technical Field

[0001] The utility model relates to the technical field of drain equipment, in particular to a drain equipment for reducing vibration of a steam pipeline. Background Art

[0002] When a steam pipe is transporting steam, some of the steam will form condensed water on the inner wall of the pipe. If the condensed water is not drained in time, it will mix with the steam and easily form water hammer in the pipe, impacting the pipe and causing it to vibrate. The conventional solution is to connect a drain device to the pipe to drain the condensed water in the pipe in time.

[0003] Currently, the most common steam trap equipment on the market is steam trap, which has a metal valve shell as the main body and a float installed inside. There is a temperature-sensitive air valve on the top of the valve shell that automatically exhausts air through a temperature-sensitive liquid, and a steam trap at the bottom. There are some functional deficiencies in actual use and there is room for improvement. For example, condensed water can only enter the steam trap when it flows. During the flow, water vapor in the pipeline mixes and flows, and the steam trap between pipelines is heavier than the pipeline. It is very easy to vibrate at the connection between the pipeline and the steam trap, and it does not have the function of bottom support to prevent vibration.

[0004] Now, a new type of steam pipe vibration reducing drainage equipment is proposed to solve the above problems. Utility Model Content

[0007] The anti-vibration structure of the supporting pipeline includes a tubular support rod, which is arranged below the valve housing, and the bottom of the tubular support rod is fixedly connected to a contact plate, an extension rod is vertically inserted into the top of the tubular support rod, and a plurality of positioning holes are arranged inside the extension rod, a positioning bolt is inserted into the top of one side of the tubular support rod, a fork-shaped support rod is fixedly connected to the top of the extension rod, and both sides of the top of the fork-shaped support rod are respectively fixedly connected to a pipe mouth support bracket, and the front and rear ends of the pipe mouth support bracket are respectively provided with fixing screw eyes, and the top of the pipe mouth support bracket is sleeved with a top pressure cover, and the front and rear ends of the top pressure cover are respectively inserted with fixing screws.

[0008] Preferably, the tubular support rods are symmetrically distributed about a vertical center line of the valve housing, and the extension rods can slide up and down along the inside of the tubular support rods.

[0009] Preferably, the positioning bolts penetrate the interior of the tubular support rod and extend into the interior of the positioning holes, and the positioning holes are arranged at equal intervals.

[0014] Preferably, the outer diameter of the sealing plug is the same as the inner diameter of the sewage elbow and the downwardly extending straight pipe, and the sealing plug can slide up and down along the interior of the downwardly extending straight pipe and the sewage elbow.

[0015] Compared with the prior art, the utility model has the following beneficial effects: the steam pipe vibration reducing drainage device not only realizes the bottom support anti-vibration function, realizes the water stagnation reminder function, but also realizes the automatic sewage discharge function;

[0016] (1) By providing a tubular support rod, a contact plate, a positioning bolt, an extension rod, a positioning hole, a fork-shaped support rod, a pipe mouth support bracket, a fixing screw eye, a top pressure cover and a fixing screw, when in use, the condensate inlet is connected to the steam pipe, and the steam and condensate enter the valve shell together. The manual air bleed valve on the valve cover is opened, and a large amount of cold air or non-condensable gas is discharged from the valve shell under the push of steam and condensate. After that, the air bleed valve is closed. At this time, the steam trap mouth is in a closed state. As time goes on, the condensate flowing into the valve gradually increases, and the stainless steel hollow float floats up. The condensate is pressed into the condensate upwelling pipe along the steam trap mouth and discharged outward through the condensate discharge pipe. As the condensate decreases, the stainless steel air float floats up. After the center float touches the bottom, it blocks the drain valve mouth and the drainage stops. When installing the valve housing and other components, two sets of tubular support rods can be set up at the bottom of the valve housing. The contact plate at the bottom of the tubular support rod contacts the ground to form a support. The extension rod is pulled up to make the pipe mouth support bracket on the fork-shaped support rod support the bottom of the condensate inlet and condensate discharge pipe. Then, the positioning bolts are driven into the tubular support rod. The positioning bolts are inserted into the corresponding positioning holes to fix the height of the extension rod. The top gland is inserted into the pipe mouth support bracket, and the fixing screws are driven into the two ends of the top gland. The fixing screws are inserted into the fixing screw eyes to form a support at the bottom of the drain valve, reduce the probability of vibration of the pipe and valve at the docking position, and realize the function of bottom support anti-vibration.

[0017] (2) By setting up an external flow meter, controller and buzzer, when in use, condensate is pressed into the condensate upwelling pipe along the drain valve mouth and discharged outward through the condensate discharge pipe. The frequency of drainage depends on the amount of steam. When the drainage is stagnant for a long time, it means that the steam is suspended or there is a problem with the valve, which requires timely maintenance. When the drainage is stagnant, the external flow meter does not sense the liquid flow for a long time, and the buzzer inside the controller immediately sounds, prompting the operator to check in time, thus realizing the function of water discharge stagnation reminder;

[0018] (3) By providing a drain elbow, a downward straight pipe, a micro-electric cylinder and a sealing plug, when in use, foreign matter such as scale on the inner wall of the pipe will enter along with the condensed water, so the drainage equipment needs to be drained regularly to avoid internal blockage. The micro-electric cylinder is connected to the control terminal and can be remotely operated online. The micro-electric cylinder retracts to retract the sealing plug into the downward straight pipe, and the drain elbow is connected to the inside of the valve housing, and the sewage is discharged. When the micro-electric cylinder extends upward, the sealing plug enters the pipe mouth of the drain elbow, forming a blockage to prevent steam from escaping, thereby realizing the function of automatic draining.

[0033] Working principle: When the utility model is in use, first, the condensate inlet 2 is connected to the steam pipe, and the steam and condensate enter the valve housing 1 together, and the manual air release valve arranged on the valve cover 13 is opened. After a large amount of cold air or non-condensable gas is discharged from the valve housing 1 under the push of steam and condensate, the air release valve is closed. At this time, the steam trap mouth 20 is in a closed state. As time goes on, the condensate flowing into the valve gradually increases, and the stainless steel hollow float 14 floats up. The condensate is pressed into the condensate upwelling pipe 19 along the steam trap mouth 20 and is discharged outward through the condensate discharge pipe 15. As the condensate decreases, the stainless steel hollow float 14 touches the bottom and blocks the steam trap mouth 20, and the drainage stops. When installing the valve housing 1 and other components, two groups of tubular support rods 3 can be set up at the bottom of the valve housing 1, and the contact plate 4 at the bottom of the tubular support rods 3 contacts the ground to form a support, and the extension rod 6 is pulled up to make the pipe mouth support bracket 9 on the fork-shaped support rod 8 support the bottom of the condensate inlet 2 and the condensate discharge pipe 15, and then the positioning bolts 5 are driven into the tubular support rod 3, and the positioning bolts 5 are inserted into the corresponding positioning holes 7 to fix the height of the extension rod 6, and the top pressure cover 11 is inserted into the pipe mouth support bracket 9, and the fixing screws 12 are driven into the two ends of the top pressure cover 11, and the fixing screws 12 are inserted into the fixing screw eyes 10, so that the bottom of the steam trap can be supported, and the probability of vibration of the pipeline and valve at the docking position is reduced. Condensate is pressed into the condensate upwelling pipe 19 along the drain valve mouth 20 and discharged outward through the condensate discharge pipe 15. The frequency of drainage depends on the amount of steam. When the drainage is stagnant for a long time, it means that the steam is suspended or there is a problem with the valve, and timely maintenance is required. When the drainage is stagnant, the external flow meter 16 does not sense the liquid flow for a long time, and the buzzer 18 inside the controller 17 immediately sounds, prompting the operator to check in time. Along with the condensate, there are also foreign objects such as scale on the inner wall of the pipe, so the drain equipment needs to be drained regularly to avoid internal blockage. The micro-electric cylinder 23 is connected to the control terminal, which can be operated remotely online. The micro-electric cylinder 23 retracts to retract the sealing plug 24 into the downward straight pipe 22, and the sewage bend pipe 21 is connected to the inside of the valve housing 1, and the sewage is discharged. When the micro-electric cylinder 23 extends upward, the sealing plug 24 enters the pipe mouth position of the sewage bend pipe 21, forming a blockage to prevent steam from running out.
