DETAILED DESCRIPTION

[0023] Refer to the attached Figures 1 to 9 The content shown, an exemplary process that can be obtained by this application is to facilitate cleaning is:

[0024] A pipeline valve comprises two valve shells 05 which can be detachably connected together by bolts. After the two valve shells 05 are buckled, a valve plate 01 is rotatably connected to the middle part. A runner 03 is fixedly connected to the upper end of the valve plate 01. Filters 02 are formed on both sides of the valve plate 01. The virtual planes where the two filters 02 are located are perpendicular to the valve plate 01. When in use, the runner 03 is rotated to drive the valve plate 01 to rotate and open, so that the medium in the pipeline flows from right to left. At this time, the filters 02 on both sides of the valve plate 01 can be perpendicular to the flow direction of the medium to filter out impurities in the medium. When the medium is gas, the filter 02 can be made of special materials. When the medium is liquid, the filter 02 can block impurities in the liquid. After a period of use, the valve shell 05 can be opened to expose the two filters 02, so that the impurities blocked on the two filters 02 can be cleaned.

[0025] See attached Figures 1 to 9 The content shown, an exemplary process of dispersing internal pressure of the present application is:

[0026] The middle part of the valve housing 05 is formed with a gate cavity 13, in which a gate plate 14 capable of sealing the valve housing 05 is in sliding contact, the outer end of the gate plate 14 passes through the gate cavity 13 and is rotatably connected to a threaded rod 15, a threaded sleeve 16 is fixedly connected to the outer wall of the valve housing 05, and the threaded rod 15 is connected to the threaded sleeve 16; when closing the valve, the valve plate 01 is rotated to seal the inside of the valve housing 05, at this time, due to the effect of the medium on both sides of the valve plate 01, the pressure of the medium acts on the valve plate 01, and when the pressure acts for a long time or the pressure on both sides is different, it is easy to This causes the valve plate 01 to deform. Therefore, after the valve is closed, the present application can rotate the threaded rod 15 to make the threaded rod 15 enter the threaded sleeve 16, so that the threaded rod 15 drives the gate plate 14 to slide from the gate chamber 13 into the valve housing 05 to seal the valve housing 05, thereby using the two gate plates 14 to block the medium on both sides of the valve plate 01, so that the medium on both sides of the valve plate 01 and between the two gate plates 14 can be kept static, so that the pressure exerted on the valve plate 01 by the medium on both sides of the valve plate 01 is kept consistent, thereby avoiding deformation of the valve plate 01.

[0027] See attached Figures 1 to 9 The content shown, an exemplary process of obtaining the added medium of this application is:

[0028] A feed hole 19 is provided at the upper end of the valve housing 05 on the right side. The feed hole 19 is a stepped structure. A steel ball 20 capable of blocking the feed hole 19 is fixedly connected to the inner wall of the feed hole 19 through a tension spring, and an input pipe 21 is detachably connected to the outer end of the feed hole 19. The medium is transported to the inside of the valve housing 05 on the right side through the input pipe 21, and the pressure of the medium can be used to push the steel ball 20 away, so that the steel ball 20 pulls the tension spring to leave the feed hole 19, so that other media can enter the medium in the valve housing 05, thereby increasing the types of media. When the types of media are not increased, the tension spring can be restored to drive the steel ball 20 to block the feed hole 19, so that the medium normally flowing in the valve housing 05 will not leak out.

[0029] See attached Figures 1 to 9 The content shown in the figure can provide an exemplary process for discharging the internal medium of the present application:

[0030] A discharge hole 17 is formed at the lower end of the gate plate 14 on the left side, and a stopper 18 is slidably connected in the discharge hole 17 to block the discharge hole 17 from the left end, and a spring is fixedly connected between the stopper 18 and the gate plate 14; after closing the valve, the valve housing 05 can be blocked from both sides of the valve plate 01 by the two gate plates 14, so that the valve is closed, and then the valve plate 01 is rotated to the open state, and gas can be filled into the valve housing 05 from the input pipe 21. After the gas enters the valve housing 05, the two gate plates 1 The medium between the two gate plates 14 is discharged from the discharge hole 17 on the gate plate 14 on the left side. After the medium enters the discharge hole 17, it can push the plug 18 outward to compress the spring of the plug 18, so that the plug 18 can leave the discharge hole 17 and the remaining medium can be cleared out from between the two gate plates 14. The space around the valve plate 01 inside the valve can be emptied to avoid the medium from contacting the valve plate 01 for a long time to cause corrosion to the valve plate 01, and to avoid the liquid medium from being affected and frozen around the valve plate 01, causing the valve to be unable to open.

[0031] See attached Figures 1 to 9 The content shown in the figure can provide an exemplary process for reducing the operation of the present application:

[0032] An inner hole 06 is opened in the side wall of the lower end of the valve housing 05. The two inner holes 06 in the two valve housings 05 can be connected when the two valve housings 05 are buckled together, and the openings of the two inner holes 06 are located between the two gate plates 14; after the rotating valve plate 01 is closed, the medium in the valve housing 05 on the right side can be squeezed into the inner hole 06 as the gas enters the valve housing 05 on the right side without operating the valve plate 01 to rotate, and the medium flows into the valve housing 05 on the left side through the inner hole 06, and then is discharged from the discharge hole 17 on the gate plate 14 on the left side, so that the two valve housings 05 in the valve after closing can be connected.

[0033] See attached Figures 1 to 9 The content shown in the figure can obtain an exemplary process of avoiding leakage of the present application:

[0034] A sliding cavity 07 connected to the inner hole 06 is provided in the side wall of the lower end of the valve housing 05, and a baffle 08 capable of blocking the inner hole 06 is slidably contacted in the sliding cavity 07. The outer end of the baffle 08 is fixedly connected to a round rod 09 passing through the side wall of the valve housing 05, and a spring is fixedly connected between the round rod 09 and the outer wall of the valve housing 05; when the valve plate 01 is rotated to close the valve, due to the action of the spring, the spring can drive the round rod 09 to slide outward, and the baffle 08 is used to slide in the sliding cavity 07 to block the inner hole 06, so as to avoid the two inner holes 06 being connected to each other and causing medium leakage between the valve housings 05 on the left and right sides. When it is necessary to empty the medium inside the valve, the round rod 09 can be squeezed inward so that the round rod 09 drives the baffle 08 to slide inward and no longer blocks the inner hole 06, so that the valve housings 05 on the left and right sides can be connected to each other when air is introduced, so that the medium is discharged.

[0035] See attached Figures 1 to 9 The content shown, an exemplary process that can achieve automatic connection of this application is:

[0036] A slide rod 11 is slidably connected to the outer wall of the valve housing 05, and a slanted block 10 contacting the outer end of the round rod 09 is fixedly connected to the rear end of the slide rod 11. A tension spring is fixedly connected between the slide rod 11 and the outer wall of the valve housing 05, and a top column 12 for pushing the slide rod 11 is formed on the lower side of the outer end of the gate plate 14; after closing the valve, the threaded rod 15 is rotated to enter the threaded sleeve 16, so that the gate plate 14 moves to block the valve housing 05, and the gate plate 14 drives the top column 12 to push the slide rod 11, so that the slanted block 10 at the rear end of the slide rod 11 contacts the outer end of the round rod 09 with its own inclined surface to push the round rod 09 inward, so that the baffle 08 no longer blocks the inner hole 06, so that the two inner holes 06 are connected after being aligned, and the two valve housings 05 can be connected for use;

[0037] The round rod 09 and the inclined block 10 are both made of wear-resistant materials, which can reduce wear, increase usage strength and extend service life.

[0038] See attached Figures 1 to 9 The content shown in the figure shows that an exemplary process for improving the filtering capability of the present application is:

[0039] The surface of the filter 02 is formed with a plurality of thorns 04 protruding from the surface of the filter 02. When the valve is used on a pipe for conveying domestic sewage, the hair and hair debris in the sewage can be blocked by the filter 02. At the same time, the plurality of thorns 04 can be used to improve the blocking of wool and hair, thereby improving the filtering capacity.

[0040] See attached Figures 1 to 9An exemplary process for quickly opening the application is as follows:

[0041] The input pipe 21 is externally connected to an air source and a water source. The air source can use its own pressure to drain the medium in the two valve housings 05 to protect the valve plate 01. When the water source is introduced, the valve plate 01 can be flushed by the clean water entering between the two valve housings 05, or the valve plate 01 can be cleaned by mixing a detergent into the clean water.
