Description

Technical Field

[0001] The utility model relates to the technical field of bio-liquid fuel filling equipment, in particular to a pipeline butt joint for bio-liquid fuel filling. Background Art

[0002] Bio-liquid fuel filling machines are used to fill trucks with bio-liquid fuel. With the increasing emphasis on environmental protection, the market for bio-liquid fuel filling machines is growing, and more and more bio-liquid fuel filling machines are appearing in gas stations in many cities. The emergence of bio-liquid fuel filling machines has solved the problems of difficult, slow and tiring bio-liquid fuel filling, greatly improved the bio-liquid fuel filling efficiency, and also made contributions to environmental protection.

[0003] When filling bioliquid fuel into a storage tank, an existing bioliquid fuel filling machine (such as a flexible bioliquid fuel explosion-proof filling machine disclosed in application number 201220227374.3) first connects the output pipeline of the tanker truck with the input pipeline of the storage tank through a flange connection, then opens the valves on the output pipeline and the input pipeline, and uses the pump on the tanker truck to pump the bioliquid fuel loaded on the tanker truck into the storage tank. After filling, the valves on the output pipeline and the input pipeline are closed, and the output pipeline is disconnected from the input pipeline. However, if the worker forgets to close the valve on the input pipeline due to negligence, the bioliquid fuel in the storage tank may easily come into contact with air and deteriorate. Utility Model Content

[0004] The purpose of the utility model is to overcome the above-mentioned technical deficiencies and propose a pipe joint for filling bio-liquid fuel, so as to solve the technical problem that the input pipe of the storage tank in the prior art does not have a self-sealing function. When the bio-liquid fuel is filled into the storage tank, it is easy for the worker to forget to close the valve on the input pipe due to negligence, resulting in the bio-liquid fuel in the storage tank coming into contact with air and deteriorating.

[0005] In order to achieve the above technical objectives, the technical solution of the present utility model provides a pipe joint for filling bio-liquid fuel, comprising:

[0006] A self-sealing pipeline comprises a housing, a plugging member, and an elastic member. The housing has a cavity and is provided with a liquid inlet and a liquid outlet communicating with the cavity. The liquid outlet is used to communicate with an input pipeline of a storage tank. The plugging member and the elastic member are both disposed in the cavity. The elastic member is connected to the plugging member and the housing so that the plugging member seals the liquid inlet.

[0007] The push-in pipeline includes a push-in pipe, one end of which is used to communicate with the output pipeline of the tanker truck, and the other end is used to be detachably pushed into the cavity along the liquid inlet to communicate with the cavity.

[0008] Furthermore, a plurality of flow holes are provided on the side wall of the other end of the pushing tube. When the other end of the pushing tube pushes into the cavity, each of the flow holes is communicated with the cavity.

[0009] Furthermore, each of the flow holes is opened in a circumferential direction.

[0010] Furthermore, the self-sealing pipeline also includes a liquid inlet pipe, one end of which is connected to the liquid inlet.

[0011] Furthermore, the self-sealing pipeline also includes a first flange, which is fixedly sleeved on the other end of the liquid inlet pipe.

[0012] Furthermore, the self-sealing pipeline also includes a liquid outlet pipe, one end of the liquid outlet pipe is connected to the liquid outlet, and the other end of the liquid outlet pipe is used to communicate with the input pipeline of the storage tank.

[0013] Furthermore, the self-sealing pipeline also includes a second flange, which is fixedly sleeved on the other end of the liquid outlet pipe and is detachably fixed to the flange at the end of the input pipeline of the storage tank via the second flange.

[0014] Furthermore, the blocking member is a columnar structure, and the end of the blocking member close to the liquid inlet is an arc-shaped structure.

[0015] Furthermore, the elastic member is a spring.

[0016] Furthermore, the entry pipe also includes a third flange and a fourth flange. The third flange is fixedly mounted on one end of the entry pipe and is detachably fixedly connected to the flange at the end of the output pipe of the tanker truck via the third flange. The fourth flange is fixedly mounted at the middle part of the entry pipe. When the other end of the entry pipe is inserted into the cavity, it is detachably fixedly connected to the first flange via the fourth flange.

[0017] Compared with the prior art, the beneficial effects of the present invention include: when it is necessary to fill the storage tank with bio-liquid fuel, the other end of the push-in tube is manually pushed into the cavity along the liquid inlet, so that the other end of the push-in tube is connected to the cavity, and the output pipeline of the tank truck is connected to the input pipeline of the storage tank. In the process of the other end of the push-in tube pushing into the cavity, the push-in tube pushes the blocking part and squeezes the elastic part, and the elastic part accumulates the compressed elastic potential energy, and then opens the valves on the output pipeline and the input pipeline, and uses the pump on the tank truck to pump the bio-liquid fuel loaded in the tank truck. The material is pumped into the storage tank. After filling, the valves on the output pipeline and the input pipeline are closed, and the other end of the input pipe is drawn out of the cavity along the liquid inlet. At this time, the elastic member releases the compressed elastic potential energy and re-seals the blocking member at the liquid inlet. The bio-liquid fuel filling pipe joint has a self-sealing function. When the bio-liquid fuel is filled into the storage tank, the blocking member can be sealed at the liquid inlet under the action of the elastic member, thereby avoiding the situation where the bio-liquid fuel in the storage tank is exposed to air and deteriorates due to the worker's negligence of forgetting to close the valve on the input pipeline.

[0024] When it is necessary to fill the storage tank with bio-liquid fuel, the other end of the push-in tube 210 is manually pushed into the cavity 111 along the liquid inlet 112 in a detachable manner, so that the other end of the push-in tube 210 is connected with the cavity 111, thereby achieving the docking of the output pipeline of the tanker and the input pipeline of the storage tank. In the process of the other end of the push-in tube 210 pushing into the cavity 111, the push-in tube 210 pushes the blocking member 120 and squeezes the elastic member 130. The elastic member 130 accumulates compressive elastic potential energy, and then opens the valves on the output pipeline and the input pipeline, and uses the pump on the tanker to pump the bio-liquid fuel loaded on the tanker into the storage tank. In the process, after the filling is completed, the valves on the output pipeline and the input pipeline are closed, and the other end of the push-in tube 210 is drawn out of the cavity 111 along the liquid inlet 112. At this time, the elastic member 130 releases the compressed elastic potential energy and re-seals the blocking member 120 at the liquid inlet 112. The bio-liquid fuel filling pipeline joint has a self-sealing function. When the bio-liquid fuel is filled into the storage tank, the blocking member 120 can be sealed at the liquid inlet 112 under the action of the elastic member 130, thereby avoiding the situation where the worker forgets to close the valve on the input pipeline due to negligence, resulting in the bio-liquid fuel in the storage tank coming into contact with air and deteriorating.

When the other end of the push-in tube 210 pushes into the cavity 111, the other end of the push-in tube 210 will abut against the blocking member 120 and push the blocking member 120. Conversely, the blocking member 120 will block the other end of the push-in tube 210. The flow holes 211 are provided on the side wall of the other end of the push-in tube 210, so that the push-in tube 210 can be connected with the cavity 111 via each of the flow holes 211.

[0026] As a preferred embodiment, please refer to Figure 2 and Figure 3 Each of the flow holes 211 is opened in a circumferential direction, so that the bio-liquid fuel in the inlet tube 210 can evenly enter the cavity 111 from the inlet tube 210 .

[0030] As a preferred embodiment, please refer to Figure 2The self-sealing pipeline 100 also includes a second flange 170, which is fixedly mounted on the other end of the liquid outlet pipe 160 and is detachably connected to the flange at the end of the input pipeline of the storage tank via the second flange 170, so that the connection between the liquid outlet pipe 160 and the input pipeline of the storage tank is detachable, which facilitates the maintenance of the input pipeline of the storage tank.

[0031] As a preferred embodiment, please refer to Figure 2 and Figure 3 The blocking member 120 is a columnar structure, and the end of the blocking member 120 close to the liquid inlet 112 is an arc-shaped structure, which can improve the blocking effect of the blocking member 120 on the liquid inlet 112.

When the other end of the push-in pipe 210 pushes into the cavity 111, it is detachably fixedly connected to the first flange 150 via the fourth flange 230, which facilitates the detachable connection between the push-in pipe 210 and the liquid inlet pipe 140.

[0034] In order to better understand the present invention, the following Figure 1 - Figure 3 The working principle of the technical solution of the utility model is described in detail:

[0035] When it is necessary to fill the storage tank with bioliquid fuel, the other end of the push-in tube 210 is manually slid along the liquid inlet pipe 140 into the cavity 111, and the fourth flange 230 is detachably fixed to the first flange 150. At this time, each of the flow holes 211 is connected to the cavity 111, so that the output pipeline of the tanker truck and the input pipeline of the storage tank are connected. In the process of the other end of the push-in tube 210 pushing into the cavity 111, the push-in tube 210 will push the blocking member 120 and squeeze the elastic member 130. The elastic member 130 accumulates compressive elastic potential energy, and then opens the valves on the output pipeline and the input pipeline, and uses the pump provided by the tanker truck to fill the tanker truck. The loaded bio-liquid fuel is pumped into the storage tank. After filling, the valves on the output pipeline and the input pipeline are closed, and the other end of the push-in tube 210 is drawn out of the cavity 111 along the liquid inlet pipe 140. At this time, the elastic member 130 releases the compressed elastic potential energy and re-seals the blocking member 120 at the liquid inlet 112. The bio-liquid fuel filling pipeline joint has a self-sealing function. When the bio-liquid fuel is filled into the storage tank, the blocking member 120 can be sealed at the liquid inlet 112 under the action of the elastic member 130, thereby avoiding the situation where the worker forgets to close the valve on the input pipeline due to negligence, resulting in the bio-liquid fuel in the storage tank coming into contact with air and deteriorating.

[0037] (1) Manually slide the other end of the push-in tube 210 along the liquid inlet tube 140 into the cavity 111, and make the fourth flange 230 and the first flange 150 detachably fixed. At this time, each of the flow holes 211 is connected to the cavity 111, realizing the docking of the output pipeline of the tanker truck and the input pipeline of the storage tank. In the process of the other end of the push-in tube 210 pushing into the cavity 111, the push-in tube 210 pushes the blocking member 120 and squeezes the elastic member 130, and the elastic member 130 accumulates compressive elastic potential energy;

[0038] (2) The other end of the push-in tube 210 is pulled out of the cavity 111 along the liquid inlet tube 140. At this time, the elastic member 130 releases the compressed elastic potential energy and re-seals the blocking member 120 on the liquid inlet 112, thereby achieving self-sealing of the liquid inlet 112.

[0039] (3) The bio-liquid fuel filling pipe joint has a self-sealing function. When the bio-liquid fuel is filled into the storage tank, the sealing member 120 can be sealed at the liquid inlet 112 under the action of the elastic member 130, thereby preventing the bio-liquid fuel in the storage tank from being deteriorated due to contact with air due to the worker's negligence and forgetting to close the valve on the input pipe.
