[0002] In a purified water preparation system, a sampling valve is a crucial and essential component. This is because there are extremely strict requirements for water quality in pharmaceutical production. To ensure that the quality of purified water always meets relevant standards and regulations, pharmaceutical manufacturers need to regularly and regularly conduct comprehensive and in-depth sampling and testing of the water quality of purified water production.

[0003] Traditional methods for sampling purified water mostly use a chuck interface sampling valve. However, during the actual operation of opening the valve for sampling, due to the too high internal water pressure, water often splashes outwards. This water splash not only wets the surrounding environment but may also cause sample contamination. To avoid the adverse effects brought by these problems, it is usually necessary for the staff to wipe it in time. Moreover, after the use of the output port of the sampling valve, it is exposed to the outside for a long time and is prone to dust accumulation, which brings inconvenience to the subsequent sampling and cleaning work of the staff.

Specific embodiments

[0024] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] The first embodiment

[0026] Please refer to Figure 1 、 Figure 2 、 Figure 3 , wherein, Figure 1 is a schematic structural view of the first embodiment of a sanitary sampling elbow provided by the present utility model; Figure 2 is Figure 1 a schematic structural view of another perspective shown; Figure 3 is Figure 1 a schematic cross-sectional view of the bellows shown. A sanitary sampling elbow includes: a connecting chuck 1;

[0027] a pipe body 2, the pipe body 2 is fixedly connected to one side of the connecting chuck 1, and a capillary channel head 21 is fixedly installed at the output end of the pipe body 2;

[0028] a retaining ring 3, the retaining ring 3 is fixedly installed on the outer side surface of the pipe body 2, a bellows 31 is fixedly installed on one side of the retaining ring 3, a protective ring 32 is fixedly installed at one end of the bellows 31, a rotating seat 34 is fixedly installed on one side of the protective ring 32, a rotating shaft 35 is fixedly installed on the inner side surface of the rotating seat 34, a rotating plate 36 is rotatably connected to the outer side surface of the rotating shaft 35, a torsion spring 37 is fixedly installed on one side of the rotating plate 36, one end of the torsion spring 37 is fixedly installed on one side of the inner side surface of the rotating seat 34, a cover plate 38 is fixedly installed at one end of the rotating plate 36, and a rubber pad 39 is arranged on one side of the cover plate 38;

[0029] a spring 5, the spring 5 is arranged on the inner side surface of the bellows 31 and sleeved on the outer side surface of the pipe body 2.

[0030] The input and output ports of the pipe body 2 are bent at 45 degrees, so as to facilitate insertion into the sampling bottle.

[0031] A gasket 11 is fixedly installed on the other side of the connecting chuck 1.

[0032] A moving ring 33 is fixedly installed at one end of the inner side surface of the protective ring 32, and the inner side surface of the moving ring 33 is attached to the outer side surface of the pipe body 2.

[0033] The spring 5 is arranged between the moving ring 33 and the retaining ring 3.

[0034] A limiting ring 4 is fixedly installed on the outer side surface of the pipe body 2, and the limiting ring 4 is arranged on one side of the moving ring 33.

[0035] When the elasticity of the spring 5 is in use, it always pushes the protective ring 32 downward, so that the protective ring 32 drives one side of the moving ring 33 to abut against one side of the limiting ring 4. The limiting ring 4 can prevent the protective ring 32 from falling off from the upper surface of the pipe body 2;

[0036] A corrugated pipe 31 is sleeved on the outer side surface of the pipe body 2. In this way, when in use, it can also play a role in protecting the pipe body 2;

[0037] One end of the torsion spring 37 is connected to the rotating plate 36, and the other end is connected to the inner side surface of the rotating seat 34, so that the elasticity always drives the cover plate 38 and the rubber pad 39 to press on one end of the protective ring 32.

[0038] The working principle of a sanitary sampling elbow provided by the present utility model is as follows:

[0039] When in use, the user connects the connecting chuck 1 and the sampling chuck, and the sealing gasket 11 plays a sealing role. When sampling is needed subsequently, the user rotates the rotating plate 36, so that the rotating plate 36 drives the cover plate 38 to rotate. At this time, the rotating plate 36 drives the torsion spring 37 to twist and store energy until the cover plate 38 drives the rubber pad 39 to be perpendicular to the pipe body 2. Then the user abuts the mouth of the sampling bottle against one side of the rotating seat 34 and is located between the rotating plate 36 and the protective ring 33. Then the user pushes the sampling bottle, so as to drive the protective ring 33 to move upward, so that the spring 5 and the corrugated pipe 31 contract until the end of the pipe body 2 with the capillary channel head 21 is inserted into the inner side surface of the sampling bottle. Then the user opens the valve to allow the liquid to enter the inner side surface of the sampling bottle.

[0040] Compared with the related technology, a sanitary sampling elbow provided by the present utility model has the following beneficial effects:

[0041] By setting a capillary channel head 21 at the output end of the tube body 2, when in use, sufficient capillary force is generated to control the characteristics of the water flow, achieving a slow, uniform and anti-splash liquid output effect. And by setting a protective ring 32 and a cover plate 38 on the outer sides of the tube body 2 and the capillary channel head 21, when not sampling, the output end of the tube body 2 and the capillary channel head 21 can be protected to prevent dust from accumulating on the output end of the tube body 2 and the capillary channel head 21, so that the staff does not need to clean the sampling port during subsequent sampling.

[0042] Second Embodiment

[0043] Please refer to Figure 4 , based on a sanitary sampling elbow provided in the first embodiment of the present application, another sanitary sampling elbow is proposed in the second embodiment of the present application. The second embodiment is only a preferred manner of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0044] Specifically, the difference of a sanitary sampling elbow provided in the second embodiment of the present application is that, for a sanitary sampling elbow, a threaded groove 6 is opened on one side of the cover plate 38, and a threaded ring 61 is threadedly connected to the inner side surface of the threaded groove 6.

[0045] The threaded ring 61 is fixedly installed on one side of the rubber pad 39.

[0046] The working principle of a sanitary sampling elbow provided by the present utility model is as follows:

[0047] After long-term use, when the aging of the rubber pad 39 reduces the fitting effect with the protective ring 33, the user can rotate the threaded ring 61 to make the threaded ring 61 threadedly connected to the inner side surface of the threaded groove 6 until it is disassembled, and then replace the rubber pad 39.

[0048] Compared with the related art, a sanitary sampling elbow provided by the present utility model has the following beneficial effects:

[0049] Through the cooperation of structures such as the threaded groove 6 and the threaded ring 61, after long-term use, when the rubber pad 39 ages, the user can rotate the threaded ring 61 to make the threaded ring 61 threadedly connected to the inner side surface of the threaded groove 6, so as to replace the rubber pad 39, which is convenient for the user to use.

[0050] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly.
