The embodiment of the application improves on the basis of the conventional stop valve, the filter 400 is additionally arranged, the filter 400 is utilized to purify the fluid in the pipeline by using the materials such as the filter element 420 of the filter 400, and the filter 400 has certain permeability, so that excessive pressure loss can not be generated, and the purification of the internal environment of the pipeline can be realized on the basis of ensuring the smoothness of the fluid; in addition, the upstream pipe 110 and the downstream pipe 120 are provided with plugging members corresponding to the filter 400, and in the installed state, the filter 400 is plugged into the end regions of the upstream pipe 110 and the downstream pipe 120 to realize the pipe penetration, and in fig. 5, when the filter 400 needs to be removed for cleaning, the upstream water stop 210 and the downstream water stop 310 are abutted against the pipe orifice due to the elastic connection property, so that the upstream pipe 110 and the downstream pipe 120 are respectively plugged, that is, the shut-off is realized by standing a horse while the filter 400 is removed, and the shutdown treatment of the liquid cooling system is not required. Therefore, by combining the structural characteristics, the embodiment of the application has remarkable practicability.

Referring to fig. 4, the filter 400 includes a filter cartridge 410 and a filter element 420, the filter element 420 is disposed in the filter cartridge 410, the filter element 420 may be filled with a porous medium, a filter screen, and other materials having a filtering effect, and the filter element 420 itself has a certain permeability, so that a large pressure loss is not caused to a pipeline, a purifying effect can be achieved to fluid in the pipeline, impurities in the pipeline can be intercepted, and when the impurities in the pipeline need to be cleaned, the cleaning to the internal environment of the pipeline can be completed by removing the filter 400 for cleaning and reinstalling.

As a cylindrical structure, two ends of the filter cartridge 410 are open, one end of the filter cartridge 410 is abutted against the upstream water stop 210, the other end is abutted against the downstream water stop 310, the circumferential surfaces of the edge regions of the two ends of the filter cartridge 410 are respectively provided with a hollow structure 430, the pipe body 100 is communicated with the inside of the filter cartridge 410 through the hollow structure 430, in the actual use process, fluid in the upstream pipeline 110 can enter the filter 400 through the hollow structure 430 at one end of the filter cartridge 410, and then enter the downstream pipeline 120 through the hollow structure 430 at the other end of the filter cartridge 410, so that the through and the filtering of the upstream pipeline 110 and the downstream pipeline 120 are realized.

In order to improve the plugging success rate, the problem of leakage caused by the inability to quickly assemble and disassemble the filter 400 is prevented, the filter cartridge 410 has a cylindrical structure, the upstream plug-in port 111 and the downstream plug-in port 121 have circular hole structures, and the plugging of the circular body is favorable for realizing quick plugging without considering the azimuth condition. The outer diameter of the filter cartridge 410 is adapted to the caliber of the upstream plug interface 111 and the caliber of the downstream plug interface 121, and the sizes and dimensional tolerances of the filter cartridge 410, the upstream plug interface 111 and the downstream plug interface 121 are designed in advance to ensure that the filter cartridge 410 is not easy to leak out due to oversized gaps after being plugged into the upstream pipe 110 and the downstream pipe 120.

Referring to fig. 4 and 5, the shut-off principle of the embodiment of the present application is that, when the filter 400 is removed, the upstream water stop 210 abuts against the upstream plug port 111 to block the upstream pipeline 110, and the downstream water stop 310 abuts against the downstream plug port 121 to block the downstream pipeline 120. The basis of realizing the foregoing operation is that the plugging area of the upstream water stop 210 is larger than that of the upstream plug interface 111, and the plugging area of the downstream water stop 310 is larger than that of the downstream plug interface 121, for this reason, in the embodiment of the present application, the end portion of the upstream pipe 110 is provided with the upstream sealing plate 130, and the upstream plug interface 111 is formed in the middle of the upstream sealing plate 130; the end of the downstream pipe 120 is provided with a downstream sealing plate 140, and the downstream plug-in port 121 is formed in the middle of the downstream sealing plate 140; up to this point, both the upstream plug interface 111 and the downstream plug interface 121 may be set small enough to be effectively plugged by the corresponding water stop.

It is added that the end surfaces of the upstream water stop member 210, the downstream water stop member 310, and the end surfaces of the two sides of the filter cartridge 410 are perpendicular to the flowing direction of the filter cartridge 410, and intercept the fluid in the direction perpendicular to the traveling direction of the fluid, so as to achieve the highest possible intercepting efficiency.

The upstream water stop 210 and the downstream water stop 310 are both in a truncated cone structure, and the outer diameter of the upstream water stop 210 gradually increases along the direction from the other end of the upstream pipe 110 to the upstream plug port 111; the outer diameter of the downstream water stop 310 gradually increases along the direction from the other end of the downstream pipe 120 to the downstream plug connector 121. Compared with the setting such as the shutoff plate, the round-table-shaped shutoff structure can provide higher compressive strength in the abutting process of the filter cylinder 410, reduce the deformation risk of the water stop member, and can reduce the space for fluid to flow as much as possible, so that the fluid can travel along the inclined planes of the upstream water stop member 210 and the downstream water stop member 310, and the influence on the flow velocity is reduced.

Referring to fig. 4, regarding the installation structure of the upstream sealing member 210, the upstream sealing portion 200 further includes an upstream bracket 220 and an upstream elastic member 230, wherein the upstream bracket 220 is fixedly disposed at a position of the upstream pipe 110 away from the upstream plug port 111, the upstream elastic member 230 connects the upstream bracket 220 and the upstream sealing member 210, and the upstream elastic member 230 is disposed to extend along the length direction of the upstream pipe 110, so that the upstream sealing member 210 can rebound along the length direction of the upstream pipe 110; similarly, the downstream sealing part 300 further includes a downstream bracket 320 and a downstream elastic member 330, where the downstream elastic member 330 is extended along the length direction of the downstream pipe 120, and the downstream sealing member 310 can rebound along the length direction of the downstream pipe 120. The upstream water stop 210 always has a tendency to abut against the upstream plug interface 111 and the downstream water stop 310 always has a tendency to abut against the downstream plug interface 121 under the influence of the extrusion action of the filter 400 and the reaction force of the respective elastic members, so that the filter 400 can be effectively pressed by the first trend, and the corresponding pipelines can be quickly plugged by the upstream water stop 210 and the downstream water stop 310 when the filter 400 is detached, so that a substantial basis is provided for online detachment of the filter 400.

Specifically, the upstream elastic member 230 and the downstream elastic member 330 are both springs, and in order to provide good guiding and external protection for the springs, the upstream elastic member 230 and the downstream elastic member 330 are each sleeved with a guide cylinder 500, one end of the guide cylinder 500 in the upstream pipe 110 is fixedly connected with the upstream support 220 (or integrally formed with the upstream support 220), and the distance from the guide cylinder to the upstream sealing plate 130 is greater than the thickness of the upstream water stop 210, so as not to prevent the upstream water stop 210 from collapsing when being abutted by the filter cylinder 410; similarly, one end of the guide cylinder 500 in the downstream pipe 120 is fixedly connected to the downstream support 320 (or integrally formed with the downstream support 320), and the distance from the guide cylinder 500 to the downstream sealing plate 140 is greater than the thickness of the downstream sealing member 310. The inner diameter of the guide cylinder 500 should be larger than the outer diameters of the upstream elastic member 230 and the downstream elastic member 330 to ensure proper expansion and contraction of the upstream elastic member 230 and the downstream elastic member 330.

The embodiments of the present utility model have been described in detail with reference to the accompanying drawings, but the present utility model is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present utility model. Furthermore, embodiments of the utility model and features of the embodiments may be combined with each other without conflict.
