Description

Self-flow valve control injection barrel

technical field

The utility model belongs to the field of barrel packaging, in particular to a self-flow valve-controlled injection molding barrel.

Background technique

At present, the injection-molded barrels used for the maintenance of large passenger and freight vehicles and engineering vehicles, containing more than 10 liters of lubricating oil or antifreeze, are composed of a barrel body and a barrel cover. The side wall and the lid are rotary bodies with circular grooves, which are formed by the tearing ring, the outer edge, the top surface of the lid, the inner edge, and the overlapping surface connected end to end, and the groove is surrounded by the inner edge and the overlapping surface , the bottom surface is the stacking surface, and the inner diameter of the groove is slightly larger than the outer diameter of the bottom of the barrel. The bottom of the upper injection molded barrel can be stacked in the groove of the lower injection molded barrel cover and is limited by the inner edge. There is a concave platform on the edge of the surface, and a telescopic tube for pouring out the oil is welded in the concave platform. There is a pull ring tearing film inside, and a tearing outer cover is welded on the outside at the same time. The stretching of the telescopic tube can make the telescopic tube The spout protrudes from the top surface of the lid to reduce oil spillage on the groove during the pouring operation.

Before the oil is filled in the existing injection barrel, it is necessary to pull off the tear cap, then stretch the telescopic tube, and unscrew the tear cap, then hold the pull ring, tear off the tear film of the pull ring, and then fill it. Operation, in the low temperature environment in winter, the stretching tube is hardened at low temperature to make the above stretching operation more difficult, affecting normal use.

For the above-mentioned existing injection molding barrel, when the oil in the barrel is to be poured out and filled to the engine filling port, it is impossible to directly align or insert the telescopic tube into the engine filling port for filling, because there will be a When the oil injection barrel is tilted at a small angle, the oil inside will overflow from the telescopic tube; so the current conventional filling operation is to use a funnel for auxiliary diversion filling, insert the funnel into the engine filling port and hold it by one person Hold the funnel, and another person performs the pouring and filling operation; when pouring, it is often due to improper operation, such as tilting the packaging barrel before it is aligned with the funnel, or the angle of inclination is too large and the speed is too fast, causing the oil to spill out of the funnel ;During the filling process, due to the vacuum caused by the reduction of oil in the barrel, the oil is sucked back and the oil is splashed out of the funnel; the filling port of some engines is on the side of the engine and the distance from the plane of the engine compartment is relatively long However, the funnel cannot be inserted, and the filling port of the engine can only be poured and filled from a distance, which makes it easier for the oil to spill out of the filling port of the engine; If the filling operation is stopped midway, the existing method is to stop toppling and lift the injection barrel halfway, and this process will cause oil to be spilled and cause waste.

The filling operation with funnel auxiliary filling or direct dumping is performed by the operator holding the injection barrel weighing more than ten kilograms. At the same time, the operator needs to control the pouring speed at any time according to the liquid inlet status of the funnel or the engine filling port. And to adjust the filling flow, it is conceivable that the filling operation is very laborious.

The cooler of the automobile engine is a circulation system with a capillary structure. It is required to fill the antifreeze at a slow speed and flow. Otherwise, the air in the cooler will be difficult to discharge and the filling operation will not be possible. At the same time, the antifreeze will overflow. The above described slow flow filling operation is more time-consuming and laborious than the conventional filling operation.

Since there is a groove on the barrel cover, and the telescopic tube for pouring out the oil is arranged on the bottom surface of the groove, at the end of pouring and filling, a part of the oil remains in the cavity formed by the groove and the side wall of the barrel mouth It is impossible to pour out all the injection molding barrels, and the residual oil can only be poured out by prying off the barrel lid; however, the standard for the buckle and seal between the barrel body and the barrel lid used to pack lubricating oil or antifreeze is very high, and the difference between the two The fit of the barrel is set to interference fit, and it is very laborious to pry off the lid, so most users have no choice but to give up the residual oil, resulting in waste.

For each existing injection molding barrel, the oil that is wasted (including residual oil) during one filling operation is about 0.3kg, and each vehicle is maintained once a month. According to the current national large-scale passenger, freight vehicles and engineering vehicles If the total amount is calculated as 100 million vehicles, 360,000 tons of oil will be wasted due to the use of existing injection barrels in the country every year, causing large-scale environmental pollution at the same time.

In summary, the existing injection barrels have the following disadvantages and deficiencies:

a. During conventional oil filling, it is necessary to use a funnel for auxiliary filling, which may easily cause oil flushing and waste. Vacuum will be generated in the barrel, which will cause oil suction and impact, resulting in different degrees of oil waste. It is not easy to implement remote filling and The filling operation is stopped halfway. During the filling process, the operator needs to monitor the liquid flow throughout the process, which is labor-intensive and labor-intensive. The slow-speed and slow-flow filling operation is even more laborious;

b. There is residual oil in the injection barrel at the end of the filling operation, which is inconvenient to recycle, resulting in waste of oil;

c. There are complicated auxiliary operation procedures before the filling operation.

detailed description

The technical scheme of the utility model will be described in detail below in conjunction with the accompanying drawings. The filling described herein generally refers to the operation process of transferring oil from a certain container to another container or device, and the described filling method generally refers to How to implement the operation method of the above oil transfer; hereinafter, the features, graphics or elements of the same structure are represented by the same reference numerals.

As shown in Figure 1, the existing injection-molded barrel is composed of a barrel body T and a barrel cover G buckled together. The barrel body is in the shape of a cone, and there are mouth edges 1 for sealing and side skirts 2 for increasing the rigidity of the barrel body. The barrel lid is a rotary body provided with a circular groove 3, which is formed by the tearing ring 4, the outer edge 5, the cover top surface 6, the inner edge 7, and the overlapping surface 8 connected end to end, and the groove 3 is formed by the inner edge 7 Surrounded by the stacking surface 8, the bottom surface is the stacking surface 8, and the inner diameter of the groove is slightly larger than the outer diameter of the bottom of the barrel. The bottom of the upper layer of injection molded barrels can be stacked in the groove of the lower layer of injection molded barrel cover and from the inner edge 7 limit position, a recessed platform 9 is provided at the edge of the lid stacking surface, and a telescopic tube 10 for pouring out the oil is welded in it, and a pull ring tear film 11 is arranged at the mouth, and a tear film 11 is welded on the outside at the same time Crack outer cover 12, as shown in Figure 2, elongate telescoping tube can make the spout of telescoping tube stretch out cover top surface 6, to reduce oily liquid overflowing on the groove when pouring out operation. When pouring out the oil in the bucket and filling it into the engine filling port, it is impossible to directly align or insert the telescopic tube 10 into the engine filling port for filling, because the injection-molded oil filled with the oil will be filled. When the liquid barrel is tilted at a small angle, as shown in Figure 3, the oil inside it overflows from the telescopic tube 10 and overflows along the outer edge 5 of the barrel cover, and cannot approach the engine filling port at all, so funnels are used now Auxiliary diversion filling; because the bung is provided with groove 3, cover top surface 6, outer edge 5, and inner edge 7, after dumping at an optimal angle, a residual concave cavity 13 as shown in Figure 4 is formed. The internal oil cannot be completely poured out to become residual oil.

In order to solve the above-mentioned shortcomings and deficiencies of the existing injection molding barrels, the utility model provides a self-flowing valve-controlled injection molding barrel. The overall technical solution is: a liquid outlet hole and a The air inlet hole of the waterproof and breathable membrane, and the liquid outlet hole and the air inlet hole are distributed symmetrically. Place the injection barrel so that the liquid outlet is facing down, and place the injection barrel on the engine compartment in a horizontal position and fix it (the valve is closed at this time, and the oil in the barrel does not overflow), so that the injection barrel is at a position relative to the engine filling port. High liquid level, insert the outlet end of the soft conduit into the engine filling port (the outlet end of the soft conduit is an oil outlet that can move freely), then the inner cavity of the injection barrel and the outlet end of the flexible conduit form a differential pressure system, and then open the valve ,Using the pressure difference in the system to make the oil in the barrel self-flow into the engine filling port through the soft conduit; for different filling methods, it can be realized by controlling the valve operation: when it is necessary to stop the filling operation in the middle, close the valve to stop the filling ; When the slow-speed and slow-flow filling operation is required, the oil flow in the soft conduit can be changed by reducing the valve opening to reduce the diversion cross section.

The function of the flexible conduit is to make its outlet end equivalent to the freely movable oil outlet of the injection barrel, replacing the fixed outlet of the existing injection barrel, so as to solve the problem that the outlet of the existing injection barrel cannot be directly aligned or the shortcoming of inserting the engine filling port, and also solves the direct alignment or insertion operation of the remote filling port (the described soft conduit with a certain length is guided to the remote filling port for direct alignment or insertion operation ), the function of the valve is to cooperate with the needs of the filling operation steps to implement opening or closing actions and flow control actions.

Example 1: The first self-flowing valve-controlled injection molding barrel is composed of a barrel body and a barrel lid. The form of the barrel body is: as shown in Figure 5, the barrel between the mouth edge 1 and the side skirt 2 The mouth side wall 14 is provided with a septum hole 15, which is provided with a septum composed of a push-off film connected with 16 and a tear ring film 17, and the periphery of the tear ring film is connected with the hole wall; the preferred square diaphragm in this embodiment Hole 15, its diaphragm is a hinged diaphragm, and the hinged diaphragm is composed of a square push-off film 16 (thickness is 1.5-3.5mm) connected with a square annular tearing ring film 17, and the three parts of the tearing ring film are The thickness of a ring edge is relatively thin (thickness is 0.15-0.3mm, easy to be torn), and the thickness of one ring edge a is thicker (about 0.35-0.6mm); The distance is H; a film-cutting valve with a film-cutting function is connected to the outer end face of the diaphragm hole, and the film-cutting valve is provided with a film-cutting device and a catheter nozzle. The preferred embodiment of the present embodiment is a cam extrusion-cutting type slide valve 18, as shown in Figure 6 , which is assembled by valve body 19, cam 20, camshaft 21, and handle 22. The valve body is a square cavity with one side open, and its inner cavity size is the same as that of diaphragm hole 15. The conduit mouth 23 that cavity body is communicated with, the other side is provided with guide hole 24; Handle and cam are provided with flat key hole 25, and one end of cam is provided with the valve plug 26 equal to conduit mouth inner hole diameter, and the two ends of camshaft are provided with There is a flat key 27; the assembly form of the cam squeeze-cut spool valve 18 is as follows: the cam is placed in the inner cavity of the valve, and the valve plug 26 is aligned with the inner hole 29 of the catheter nozzle, and the camshaft 21 is inserted from the outer end of the guide hole 24 Insert until connecting the flat keyhole of the cam, and put the handle 22 on the end of the camshaft; It is welded and bonded with the barrel body T by an ultrasonic process. After welding, the inner cavity of the cam squeeze-cut spool valve is shown in FIG. Shown, the cam, the camshaft and the handle are connected as a whole and can slide axially (shown by the arrow in the figure), and when the valve plug 26 of the cam is inserted into the inner hole 29 of the catheter nozzle when it is pushed to slide in the direction of the catheter nozzle, the cam The squeeze-cut spool valve is closed, otherwise it is opened; as shown in Figure 7 and Figure 8, an air inlet 31 with a step is arranged on the side wall 14 of the barrel mouth opposite the diaphragm hole, and its centerline reaches the plane of the barrel mouth The distance is h, and one layer of waterproof and breathable membrane 32 is hot-pressed on the steps (this membrane can freely permeate gas and prevent liquid from penetrating, and it is used to balance the vacuum negative pressure in the barrel when filling oil); as shown in Figure 9 As shown, the barrel cover G is a rotating body formed by connecting the tearing ring 4, the outer edge 5, the cover top surface 6, the inner edge 7, and the overlapping surface 8 end to end. The tearing ring 4 and the outer edge 5 have a very thin wall thickness. The tearing edge 33 is connected so that the tearing ring can be separated along the tearing edge, and the tearing ring is provided with opening and tearing ears 34; as shown in Figure 10, a soft catheter 30 with a certain length is connected at the mouth of the catheter, After the barrel body is filled with oil, the soft conduit 30 is coiled on the side skirt step 36 formed by the barrel mouth side wall 14 and the side skirt 2 and the barrel cover G is fastened so that the cam The squeeze-cut spool valve 18 and the soft conduit 30 are packaged in the annular cavity 34 formed by the side skirt step 36 , the tear ring 4 , and the barrel mouth side wall 14 .

The diaphragm holes and valves set on the above-mentioned barrel body, when the diaphragm is not torn, the inner cavity of the barrel body is equivalent to the barrel body without diaphragm holes, and the sealing performance of the inner cavity has nothing to do with the valve. After filling the oil, ensure that it does not leak; and when the diaphragm is torn off, the inner cavity of the barrel body is connected with the inner cavity of the valve body, so that the diaphragm hole becomes a liquid outlet hole.

For the first type of self-flowing valve-controlled injection molding barrel with oil, when filling oil, tear off the opening ear of the barrel cover to separate the tear ring from the barrel cover (this auxiliary operation is very simple and fast) to expose the valve and As shown in Figure 11, place the injection molding barrel horizontally so that the diaphragm hole 15 and the cam squeeze-cut spool valve 18 are at a low liquid level, and the air inlet is at a high liquid level, and keep the injection molding barrel horizontally. The posture is freely placed on the engine compartment and fixed (the operator no longer needs to lift and hold the injection barrel during the subsequent filling operation), and because the soft conduit has a certain length, it can be very conveniently guided to the engine filling port and inserted (The same applies to the situation with a remote filling port), the above operation of turning over, placing the injection barrel and inserting the soft pipe into the engine filling port, because the diaphragm is in a complete state (not torn), so there is no oil spillage in the soft pipe .

Turning the handle 22 drives the cam 20 to rotate, and the long edge 37 of the cam profile pushes and pushes the membrane 16 so that the diaphragm is torn along the three thinner ring sides, and the thicker ring side a continues to be connected, so that the diaphragm is separated by the connected ring side The fulcrum is opened like a hinge so that the inner cavity of the bucket body communicates with the valve cavity, as shown in Figure 12, pulling the handle 22 (shown by the arrow in the figure) drives the valve plug 26 on the cam 20 to slide to the right, and the cam squeezes the sliding plug The valve 18 is opened. At this time, since the injection molding barrel is at a high position, a differential pressure system is formed between the inner cavity of the injection molding barrel and the outlet end of the soft conduit, and the oil in the barrel is automatically injected into the engine through the soft conduit by using the pressure difference in the system. In the mouth; the vacuum negative pressure generated due to the reduction of oil in the barrel during the filling process is balanced by the waterproof and breathable membrane of the air inlet hole at a high liquid level sucking the air outside the barrel (this balance process is during the entire gravity filling process continuous), so there will be no oil suction impact and waste; when it is necessary to stop the filling operation halfway, as shown in Figure 13, just push the handle 22 (shown by the arrow in the figure) to drive the valve plug on the cam 20 26 slides to the left, so that the valve plug 26 is inserted into the inner hole 29 of the catheter nozzle, and the cam extrusion type slide valve 18 is closed, and the filling operation can be stopped; The opening distance between 26 and the inner hole 29 of the conduit nozzle can reduce the diversion section of the cam squeeze-cut spool valve 18 to change the oil flow in the flexible conduit. In this embodiment, the opening of the hinged diaphragm can also be made smaller by rotating the handle. achieve the same effect.

As shown in Figure 14, when the injection barrel is placed horizontally, its diaphragm hole 15 is at the lowest position, and the residual cavity 38 is above it, so the oil in the barrel can be filled at one time without residual oil.

In the above filling operation, the injection barrel is placed on the engine compartment in a horizontal posture. After the self-flow filling starts, the operator does not need to lift the injection barrel, and can leave the filling site until the self-flow filling is completed. The filling operation is the same as holding a plastic injection barrel weighing more than ten kilograms at any time to monitor the liquid inlet status of the funnel or engine filling port and artificially control the pouring speed and flow rate, so as to realize the self-flowing oil filling operation in an unattended manner (no The human-on-duty filling method is especially suitable for slow-speed and slow-flow filling operations), which will greatly reduce the labor intensity of the operator and achieve the purpose of saving labor.

Since the valve and soft conduit are the core components of the self-flowing valve-controlled injection molding barrel, they must be delivered to the end user together with the injection molding barrel, so they can be used as a set of independent accessories for the end user when they are sold. This collocation mode is likely to cause confusion or even loss of distribution in the warehousing and logistics links; therefore, in this embodiment 1, the valve is preferably connected to the diaphragm hole of the drum body. After filling the oil, the drum body and the drum lid are fastened, and the valve It is accommodated together with the flexible conduit in the annular cavity formed by the side skirt step, the tear ring, and the side wall of the barrel mouth, ensuring that each injection barrel is equipped with a set of valves and flexible conduit.

Of course, the diaphragm hole can also be set to the structural form of a quick-change interface (such as a Luer connector), which is arranged on the side wall or bottom of the barrel body, and a receiving groove is set at the barrel cover or the bottom of the barrel body. Assemble the valve and flexible conduit in the form of accessories, and seal them in the holding tank with a self-adhesive protective film. When filling oil, take the valve and flexible conduit out of the containing tank and connect them to the diaphragm hole of the barrel body. Reach the filling function and the overall effect of the overall technical solution of the utility model.

A circular diaphragm hole is provided, as shown in Figure 15, which is a Luer taper hole 39, and the small end is provided with a septum that can be torn by connecting the tearing ring film 17 with the push-off film 16, and the periphery of the tearing ring film It is connected with the hole wall; an air inlet 31 with a step is arranged on the barrel mouth side wall 14 opposite to the diaphragm hole, and a layer of waterproof and breathable membrane 32 is hot-pressed on the step (this membrane can freely permeate gas and prevent liquid from penetrating). However, it is used to balance the vacuum negative pressure in the barrel when filling the oil); as shown in Figure 16, a valved flexible conduit F connected with a valve is set, and the valve is provided with a Luer connector 40, and the Luer connector The ends are evenly provided with diversion holes 41 and ejector pipes 42, and the valves of the soft conduits with valves described in this embodiment are selected from existing ball valves 43; The rotating body formed by end-to-end rotation along the top surface of the lid, the inner edge, and the overlapping surface. The tearing ring is provided with opening and tearing ears 34; Assemble the soft conduit with valve in the form of an accessory, and seal it in the containing groove with a self-adhesive protective film.

The Luer taper hole with the diaphragm set on the above barrel body, when the diaphragm is not torn, the inner cavity of the barrel body is equal to the barrel body without the Luer taper hole, after the self-flow valve-controlled injection molding barrel is filled with oil, it is guaranteed that it will not Leakage; and when the septum is torn, the Luer cone with the septum becomes the outlet hole.

The Luer connector is a pipe joint with a 6/100 taper and has a frictional self-locking function. It is used in conjunction with a tapered Luer taper hole, and is usually used in occasions that require quick connection.

For the second type of self-flowing valve-controlled injection barrels filled with oil, when filling oil, tear off the self-adhesive protective film and take out the flexible conduit with valve from the containing tank, tear off the opening ear of the barrel cover to make the tear ring Separate from the barrel cover to expose the diaphragm hole, insert the Luer connector 40 into the diaphragm hole 39, as shown in Figure 18, make the ejector tube 42 at the end close to the ejector membrane 16, pinch the ball valve 43 and squeeze the Luer connector firmly , so that the push-off film 16 is squeezed and separated along the tear ring film 17, and the Luer connector is continued to be pushed to make the outer tapered surface fit and self-lock with the Luer taper hole of the diaphragm hole. At this time, the guide on the Luer connector The orifice 41 is just aligned with the inner wall of the barrel; the separated push-off film 16 floats in the oil in the barrel, and because its diameter is larger than the inner hole diameter of the push-off pipe and has a certain thickness, after the oil in the barrel has flowed out, it will The pushed pipe is blocked in the barrel and will not be injected into the engine filling port with the oil; close the valve, place the injection barrel horizontally so that the diaphragm hole faces downward, and place the injection barrel freely on the engine compartment in a horizontal position and fix it. Make the injection barrel at a high liquid level relative to the engine filling port, insert the outlet end of the soft conduit into the engine filling port, then the inner cavity of the injection molding barrel and the outlet end of the soft conduit form a differential pressure system, as shown in Figure 19, open the ball valve 43 , using the pressure difference in the system to make the oil in the barrel pour into the engine filling port through the flexible conduit 30; other filling operation methods and functional effects are exactly the same as those described in Embodiment 1, and will not be repeated here.

As can be seen from Examples 1 and 2, it is practical to set diaphragm holes distributed opposite to each other on the barrel body of the injection molding barrel and hot-pressed air inlet holes with waterproof and breathable membranes, and to connect soft conduits and use the horizontal injection molding barrel method for self-flow filling. The new core technology scheme, its conventional filling, remote filling, mid-stop filling, slow flow filling and other operation methods are very simple, fast and convenient, and realizes no oil spilling during the filling process and waste; no vacuum negative pressure in the barrel will not cause oil back suction and splashing; the oil in the barrel can be filled at one time without residual oil.

Since the self-flowing valve-controlled injection molding barrel has the diaphragm hole arranged on the barrel body, there is no need to arrange a telescopic tube on the barrel lid, which reduces the complicated auxiliary operation procedures existing in the existing injection molding barrel before the filling operation.

In summary, the differential pressure self-flow valve-controlled filling method and the self-flow valve-controlled injection barrel of the present invention solve all the shortcomings and deficiencies of the existing injection barrels, and at the same time, unattended filling operations can be implemented.

The self-flowing valve-controlled injection molding barrel of the utility model has a diaphragm hole on the barrel body. When the diaphragm is not torn, the inner cavity of the barrel body is the same as that of the existing injection molding barrel without a diaphragm hole. The sealing performance of the injection molding barrel is the same as that of the matching valve. Sealing is irrelevant, the valve is only used when filling, and when filling oil, the pressure on the valve is very low (the self-weight pressure of the oil in the barrel), so the requirements for the matching valve are very low, as long as it reaches No leakage is enough.

Therefore, for the second type of self-flowing valve-controlled injection molding barrel, the valve matched with the soft conduit with valve can be any of ball valve, butterfly valve, gate valve, globe valve, plug valve, diaphragm valve, slide valve, pinch valve A sort of.

For the valve matched with the flexible conduit with valve, the ideal solution is to use a pinch valve, which is to clamp the pipe clamp or roller clamp on the outside of the flexible conduit, and squeeze the flexible conduit to make it cut off, otherwise it will be turned on; The tube clamp has self-locking ratchets, and the roller tube clamp is the same as the roller flow regulator on the medical infusion set; the pinch valve is low in cost, simple in structure and convenient for popularization and application.

The film-cutting valve described in the first self-flowing valve-controlled injection barrel has both a film-cutting function and a valve function. For those skilled in the art, many corresponding types of valves can be found to be applied to the film-cutting valve. It is the same as the technical design principle of the utility model, and should also belong to the protection scope of the utility model.

Therefore, the cut-film valve may be any one of a ball valve, a disc valve, a plug valve, a slide valve, a gate valve, and a cone valve.

The film-cutting valve is a cam extrusion-cutting type spool valve 18, as shown in Figure 6, which is assembled by a valve body 19, a cam 20, a camshaft 21, and a handle 22, and one side of the valve body is open. Square cavity, the size of the inner cavity is the same as the diaphragm hole 15, a catheter nozzle 23 is provided on one side, and a guide hole 24 is provided on the other side; the handle and the cam are provided with a flat keyhole 25, and the contour surface of the cam is provided with a long edge 37. Short edge 28, one end of which is provided with a valve plug 26 equal to the inner hole of the conduit nozzle, and the two ends of the camshaft are provided with flat keys 27; In the body cavity, and align the valve plug 26 with the inner hole 29 of the catheter nozzle, insert the camshaft 21 from the outer end of the guide hole 24 to the flat keyhole connecting the cam, and put the handle 22 on the end of the camshaft to form a cam squeeze-cut sliding plug valve.

The film-cutting valve is a push plug valve 49, as shown in Figure 20, it is assembled by a valve body 19, a rotary valve plug 46, and a hand wheel 47, and the valve body is a circular valve with one side open. Cavity, one side of which is provided with a catheter nozzle 23 communicating with the cavity, the back of the open surface of the valve body is provided with a guide hole 24, the handle is provided with a flat keyhole 25, and one end of the rotary valve plug 46 is a hollow bell-shaped body. The wall is provided with a waist-shaped valve plug hole 48, and the other end is connected to the valve plug shaft, and the shaft end is provided with a flat key. Through the guide hole 24, set the hand wheel 47 on the valve plug shaft to form a push-type plug valve; turning the hand wheel can make the rotary valve plug 46 rotate in the circular valve cavity, and the waist-shaped valve plug hole and the inner hole of the catheter mouth 29 When aligned, the push-type cock valve is turned on, otherwise it is closed; as shown in Figure 21, the open surface of the push-type cock valve 49 is face-to-face with the barrel surface provided with a circular diaphragm hole, and ultrasonic waves are used to The process welds it to the barrel body, connects the flexible conduit 30 at the conduit nozzle 23 and coils it on the side wall of the barrel mouth; The wheel can make the rotary valve plug 46 slide axially inward, thereby pushing the circular diaphragm and separating it from the diaphragm hole (the principle of cutting the film is similar to that of Embodiment 2); are exactly the same, and will not be repeated here.

After the self-flow filling starts, as the oil in the barrel decreases, the inner cavity of the barrel will generate a vacuum negative pressure. Since the waterproof and breathable membrane can freely pass through the gas and prevent the liquid from penetrating, the air outside the barrel is sucked in through the waterproof and breathable membrane of the air intake hole. In order to balance the vacuum negative pressure in the bucket, preferably, the waterproof and gas-permeable membrane is a hydrophobic polytetrafluoroethylene waterproof and gas-permeable membrane.

In order to guide the flexible conduit to the fuel filler port of the engine, the length of the flexible conduit is 100-800mm and the diameter is 8-16mm.

Since the barrel body is a cone, in order to make the air intake hole at the highest position when the injection barrel is placed horizontally, it is best to set it at the large end of the barrel body, and the distance h from the center line to the barrel mouth plane is 10-20mm.

In order to facilitate the smooth tearing of the tearing ring film, the thickness of the tearing ring film of the diaphragm hole is 0.1-0.3mm, the thickness of the push-off film is 1.5-3.5mm, and the distance from the centerline of the diaphragm hole to the barrel mouth plane is The distance H is 15-50mm.
