Description

Technical Field

[0001] The utility model belongs to the technical field related to bellows, and particularly relates to a valve type bellows with an oil leakage detection function. Background Art

[0002] Bellows refers to a tubular elastic sensitive element connected by foldable corrugated sheets along the folding and stretching direction. Bellows are widely used in instruments and meters. Their main purpose is to be used as a measuring element of pressure measuring instruments to convert pressure into displacement or force. The wall of the bellows is thinner and the sensitivity is higher. The measuring range is from tens of Pa to tens of MPa. The open end of the bellows is fixed, the sealed end is in a free state, and an auxiliary spiral spring or reed is used to increase the elasticity.

[0003] However, the existing bellows do not have the function of leak detection for the liquid flowing inside the bellows. Therefore, when the bellows are installed on the corresponding equipment for oil transmission, it is impossible to ensure whether there is oil leakage during the transmission process. At the same time, when the bellows are used, it is not convenient to quickly seal the bellows, so it is not convenient to quickly cut off the internal space of the bellows. To this end, we provide a valve-type bellows with oil leakage detection function to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a valve type bellows with an oil leakage detection function. By placing a hollow ball block in the valve body, the interior of the bellows body can be easily isolated. At the same time, oil leakage arc strips are installed at the positions of the two ends of the bellows body, which can facilitate observation of whether there is oil leakage at the pipe mouth position of the bellows body.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is a valve type bellows with an oil leakage detection function, comprising a bellows body; a valve body is fixed at the middle position of the bellows body, a hollow ball block with an orifice facing the same direction as the bellows body orifice is arranged inside the valve body, an upper portion of the valve body peripheral side is fixedly connected with an axis block, a connecting column rotatably connected to the axis block through a bearing is fixed on the peripheral side of the hollow ball block, a rotating plate is arranged directly above the connecting column, oil leakage arc strips are arranged at the left and right port positions of the bellows body, and the oil leakage arc strip is connected to the lower peripheral side of the bellows body port, and an arc opening is opened on the inner side surface of the oil leakage arc strip.

[0007] The utility model is further configured that an outer spiral tube is fixedly connected to the lower portion of the peripheral side of the valve body, and a threaded cover is spirally arranged at the lower end portion of the outer spiral tube.

[0008] The present utility model is further configured such that connecting bars are fixed to the opposite end faces of the two oil leakage arc bars, and sleeve rings sleeved on the corrugated pipe body are fixed to the other ends of the connecting bars.

Specific Embodiment

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0027] Embodiment 1

[0028] Please refer to Figures 1 to 6 , the present utility model is a valve-type bellows with an oil leakage detection function. By having the hollow ball block 4 located in the valve body 2, it is convenient to partition the interior of the bellows body 1. At the same time, by installing the oil leakage arc strip 3 at both ends of the bellows body 1, it is convenient to observe whether there is oil leakage at the pipe orifice position of the bellows body 1.

[0029] Specifically, a corrugated pipe body 1; a valve body 2 is fixed at the middle position of the corrugated pipe body 1. A hollow spherical block 4 with an orifice having the same orientation as the pipe orifice of the corrugated pipe body 1 is arranged inside the valve body 2. An axle block 202 is fixedly connected to the upper part on the circumferential side of the valve body 2. A connecting column 401 rotatably connected to the axle block 202 through a bearing is fixed on the circumferential side of the hollow spherical block 4. A rotating plate 6 is arranged directly above the connecting column 401. Oil leakage arc strips 3 are arranged at both the left and right port positions of the corrugated pipe body 1, and the oil leakage arc strips 3 are connected to the lower week side of the port of the corrugated pipe body 1. An arc opening 303 is formed on the inner side surface of the oil leakage arc strip 3.

[0030] The operation process of this embodiment is as follows: Through the setting and use of the above structure, since the valve body 2 is fixed at the middle position of the corrugated pipe body 1, when the corrugated pipe body 1 is blocked, the rotating plate 6 can be controlled to rotate. Thus, the rotating plate 6 will drive the hollow spherical block 4 to rotate and move inside the valve body 2 through the connecting column 401, and then drive the hollow spherical block 4 to stagger inside the valve body 2, so as to facilitate the blocking work of the corrugated pipe body 1. At the same time, when the corrugated pipe body 1 is in use, since the oil leakage arc strip 3 abuts against the bottom position of the port of the corrugated pipe body 1, when oil leakage occurs at the port position of the corrugated pipe body 1, the oil will flow into the inner position of the arc opening 303, and the staff can observe whether there is oil in the sliding opening, and judge whether there is oil leakage in the corrugated pipe body 1 in this way.

[0031] Furthermore, an external screw pipe 201 is fixedly connected to the lower part on the circumferential side of the valve body 2. A threaded cover 5 is spirally arranged at the lower end of the external screw pipe 201. Connecting strips 301 are fixed on the opposite end faces of the two oil leakage arc strips 3. The other ends of the connecting strips 301 are both fixed with collar rings 302 sleeved on the corrugated pipe body 1. Since the collar rings 302 are sleeved on the corrugated pipe body 1, the collar rings 302 will limit the oil leakage arc strips 3. At the same time, when it is necessary to drain the sewage inside the valve body 2, the threaded cover 5 can be unscrewed at the position of the external screw pipe 201 to open the external screw pipe 201, and then the sewage inside the valve body 2 will be discharged from the pipe orifice position of the external screw pipe 201.

[0032] Embodiment 2

[0033] Please refer to Figure 2 、 Figure 3 、 Figure 4 and Figure 6 , on the basis of Embodiment 1, through the cooperation of the strip-shaped block 403 and the concave opening 603, it is ensured that the hollow spherical block 4 is stably located in the valve body 2.

[0034] Specifically, a moving hole 404 is formed in the middle position of the upper end surface of the connecting column 401. An activity port 402 is formed at the bottom of the moving hole 404, and the diameter of the activity port 402 is smaller than the diameter of the moving hole 404. A rotating rod 601 passing through the inside of the moving hole 404 is fixed in the middle of the lower end surface of the rotating plate 6. A circular plate 602 slidably connected to the inner side surface of the activity port 402 is fixed to the lower end surface of the rotating plate 6. A strip-shaped block 403 is fixed to the inner side surface of the activity port 402 below the circular plate 602, and four strip-shaped blocks 403 are evenly arranged in a ring along the inner side surface of the activity port 402. Notches 603 are formed at the positions corresponding to the strip-shaped blocks 403 on the circumferential side of the circular plate 602. A spring 604 is fixed to the lower end surface of the circular plate 602, and the lower end surface of the spring 604 is fixedly connected to the bottom surface of the moving hole 404.

[0035] The operation process of this embodiment is as follows: When it is necessary to control the rotation of the hollow ball block 4, the user needs to move the rotating plate 6 downward. Then, the rotating plate 6 drives the circular plate 602 to move downward inside the activity port 402 through the rotating rod 601, so that the strip-shaped block 403 is inserted into the notch 603. At this time, after rotating the rotating plate 6, the rotating plate 6 will drive the connecting column 401 to rotate through the circular plate 602, and thereby drive the hollow ball block 4 to rotate inside the valve body 2. At the same time, after releasing the rotating plate 6, the spring 604 at this time will push the circular plate 602 upward, so that the strip-shaped block 403 disengages from the inside of the notch 603. Then, the rotation of the rotating plate 6 will not drive the connecting column 401 to rotate, ensuring that the hollow ball block 4 is stably located in the valve body 2.
