Embodiment：

As shown in figure 1, cooling water recirculation system 100 includes filter 110, cooling device 120, sealing device 130, entered Waterpipe 140 and outlet conduit 150；Filter 110 is arranged on abyssopelagic, and water inlet pipe is passed through with the cooling device 120 Road 140 is connected；Outlet conduit 150 is connected with cooling device 120.Outlet conduit 150 and inlet channel 140 are by piping unit 160 are spliced, and sealing device 130 is arranged on the junction of piping unit 160.The cooling water recirculation system 100 is mainly used in Cooling device 120 in cooling to industrial equipment, figure is schematic diagram, according to different application scenarios, the tool of cooling device 120 Body structure is different.

As shown in Fig. 2 sealing device 130 includes sleeve 132, two press sections 134, two seals 136；Two sealings Part 136 is separately mounted to the two ends in sleeve 132, and two press sections 134 are connected by screw at the two ends of sleeve 132, and will Seal 136 is compressed.

As shown in Figures 2 and 3, the inwall of sleeve 132 is provided at both ends with to be provided with baffle plate 1322, baffle plate 1322 and supplies pipeline The through hole that unit 160 is passed through；The end face of sleeve 132 is provided with screwed hole.Seal 136 is overall in coniform, middle provided with circle Shape through hole；Seal 136 is arranged between the inwall of the outer wall of piping unit 160 and sleeve 132, and the big end of seal 136 Towards baffle plate 1322, the middle part of seal 136 is provided with the through hole with the outer circumference surface cooperation of piping unit 160.Press section 134 Including extrusion body 1342 and adpting flange 1346, both are integrally formed.The entirety of extrusion body 1342 is cylindrical, and centre is set It is equipped with coniform endoporus；The taper of the endoporus is equal with the taper of seal 136；It is provided with the middle of adpting flange 1346 and supplies pipeline The through hole that unit 160 is passed through.

Such as Fig. 2 and Fig. 3, press section 134 first, is arranged peace by whole seal 136 when being assembled with piping unit 160 Mounted in the end for two piping units 160 for needing to connect, and ensure the big end of the conical bore of extrusion body 1342 towards connection end 162；Seal 136 is arranged to the end for the piping unit 160 for needing to connect installed in two, and ensures the circle of seal 136 Poppet surface and the female cone hole face of extrusion body 1342 coordinate；Then, the leading to through baffle plate 1322 by a piping unit 160 Hole, another piping unit 160 being attached thereto passes through the through hole of another baffle plate 1322, it is ensured that junction is located at two baffle plates Between 1322；In addition, gap should be left between the end face of adpting flange 1346 and sleeve 132, the end face of extrusion body 1342 Gap should be left between baffle plate 1322；Finally, adpting flange 1346 is connected with sleeve 132 by screw.

Due to being provided with gap, the end face and baffle plate of extrusion body 1342 between adpting flange 1346 and the end face of sleeve 132 Gap is provided between 1322, therefore when tightening the screw on adpting flange 1346, press section 134 is transported towards the direction close to roller It is dynamic.Now, the female cone hole face squeeze sealing member 136 of extrusion body 1342 so that the elastic deformation force of seal 136 is increasingly Greatly, it thereby may be ensured that good sealing.

Such as Fig. 2, Fig. 3 and Fig. 4, preferably, being additionally provided with multiple convex portions 164 in the end of piping unit 160.Convex portion 164 extend annular in shape along the excircle of piping unit 160, and the section of convex portion 164 is in semicircle shape.The endoporus table of seal 136 Face is provided with the groove matched with convex portion 164.During installation, convex portion 164 is caught in groove, and ensure the big end end of seal 136 Gap is left between face and baffle plate 1322.In addition, being provided with elastic packing between the end face of adpting flange 1346 and sleeve 132 Pad 138.Due to the presence of convex portion 164 and groove, when tightening the screw on adpting flange 1346, between convex portion 164 and groove Contact stress can be increasing, further increase sealing effectiveness.

Such as Fig. 5, filter 110 includes the first filter element 112, the second filter element 114 and connecting pipe 113.The One filter element 112 is connected with the second filter element 114 by connecting pipe 113, the second adjacent filter element 114 passes through even Adapter road 113 is connected.

First filter element 112 is made up of filter element body 116 and filter 118, and filter element body 116 is by general Thread a pipe to block and be made.The one end of first filter element 112 is used to be tightly connected with inlet channel 140 (Fig. 1), and the other end passes through close Envelope flange 1162 is sealed.Filter 118 can use filter of the prior art, filter 118 and filter element body 116 Connection.The water filtered by filter 118 is entered in filter element body 116, enters further into (the figure of inlet channel 140 1) in.

Second filter element 114 is substantially similar to the structure of the first filter element 112, and difference is, its two ends is all by close Envelope flange 1162 is sealed.

Such as Fig. 6, preferably, the delivery port in outlet conduit 150 is that position is provided with check valve 152.Due to being provided with Check valve 152, seawater can only flow out from outlet conduit 150 and can not flow backwards；Fish can also be avoided to enter cooling water circulation In system 100 (Fig. 1).

Because filter 118 is after used one end time, can there be more silt on screen pack so that filter 118 Permeability receive influence.In order to remove the silt on screen pack, it is necessary to regularly replace screen pack.But change the work of screen pack Make comparisons complexity, it is difficult to which realization is automatically controlled, and the cost for operation of manually plunging into the commercial sea is very high.In order to solve this problem, this practicality is new Type has carried out further optimization to filter 110.

Such as Fig. 6, the first stop valve is provided with the connecting pipe of the filter element 114 (Fig. 5) of outlet conduit 150 and second 115, the delivery port of the outlet conduit 150 is provided with the second stop valve 117；Set in the water inlet of the inlet channel 140 It is equipped with the 3rd stop valve 119.

When needing to clean filter 118, it is only necessary to open the first stop valve 115, simultaneously close off the second cut-off The stop valve 119 of valve 117 and the 3rd, the seawater of outlet conduit 150 can only be flowed out by filter 118, so as to by screen pack On silt wash out.After filter 118 has been cleaned, the first stop valve 115 is closed, while opening the He of the second stop valve 117 3rd stop valve 119, now, seawater are flowed into inlet channel 140 from filter 118, are flowed out from outlet conduit 150.Separately Outside, cooling water recirculation system 100 (Fig. 1) is also provided with control system (not shown), because the open and close of stop valve is grasped Make simple, can be controlled by control system, therefore without operation of manually plunging into the commercial sea.

It should be noted that the first stop valve 115, the second stop valve 117, the 3rd stop valve 119 and check valve in Fig. 6 152 be schematic diagram, does not represent its planform.

Preferred embodiment of the present utility model is the foregoing is only, the utility model is not limited to, for For those skilled in the art, the utility model can have various modifications and variations.It is all in spirit of the present utility model and former Within then, any modification, equivalent substitution and improvements made etc. should be included within protection domain of the present utility model.
