Definitions

  • the present invention relates to the technical field of mechanics, pneumatics and solution filling machines, since it provides a one-piece threaded volumetric valve. BACKGROUND OF THE INVENTION
  • the filling of a container consists in the transfer of the solution from the tank that contains it to it. What distinguishes one technology from another, is the way in which the exact volume of product to be transferred is determined, there are various systems and different technologies, which could be classified as follows:
  • Level filling they are suitable for fine and sparkling products (such as cleaning solutions).
  • Pressure filling it is achieved by controlling the flow of the product through the pipe.
  • the product remains in the manifold that feeds the tubes and a computer calculates the flow time of the required product, based on manifold pressure, nozzle size, and required filling volume.
  • Diaphragm pump it is suitable for corrosive chemicals, abrasive materials, and delicate liquids (such as blood, insulin and plasma). This fully enclosed system eliminates air bubbles in small fillings and allows precise filling.
  • Rotary trowel »da tianpo pxasión they are suitable for filling high viscosity products.
  • the nozzle is opened to the product for a specific amount of time to achieve adequate filling volume. Proper filling depends on three critical areas, filling time, product flow pressure, and filling speed.
  • Piston filler they are ideal for filling a wide range of products. These fillers, which have been designed to be robust, however, are manufactured with precision for a long trouble-free operation. The viscosity of the products can vary from 1 to 100,000 centipoise and higher. Piston fillers, also known as volumetric, are driven by a pneumatic piston, their operation is very simple.
  • a volumetric valve is the result of joining a hydraulic valve and a Woltman counter in the same body complemented with a device that allows you to manually select the amount of liquid that you want to apply and the valve will close automatically when the preset volume has passed;
  • the equipment has a cylinder, this cylinder is filled and emptied with the product, when the piston is actuated, it retracts creating a suction which causes the cylinder to fill when the piston returns displaces the product towards the container.
  • This type of filling is indicated in dense, thick products, with seeds or pulp, creams, mixtures, pasta, sauces, among others. They are very versatile and easy to use, making them an ideal option. They exist in several models and They have various combinations and measures, some have a product tank on top, in other cases the product is taken directly from the tambo or bucket to be transferred, to name a few.
  • the valve body is prestressed on a spring assembly in one direction, where the spring assembly is supported on a spring seat, the axial position of which is fixed by an expander.
  • the spring seat or the expander is placed in a threaded coupling with a fixed housing element.
  • the expander consists of a ball, which is pressed on a hole in the housing forming an elastic caulking action, which is arranged at a distance from a threaded section.
  • the dosing valve is on a fixed frame, to prevent it from moving, however, it is a device that has many components, and is not one piece, which can divide the piston and the cylinder that contains the product thanks to a threading, which is why it is a more complex device than the one of the present invention, lacks fastening means between the valve and the spring or frame, which are of simple removal for maintenance or replacement fast
  • the packaging cartridge has an inner end face that is in contact with the protrusion surface, and a threaded cylindrical surface on the outside to engage with the coupling threads in the recess of the cylindrical fluid pump.
  • the end face of the packaging cartridge has a serrated portion on the periphery of the inner edge thereof.
  • a ring-shaped seal is disposed in the toothed portion creating an effective seal at high pressure between the nut of the packaging cartridge and the cylinder means of the fluid pump.
  • a front bushing is designed to increase the volumetric efficiency of the pump head.
  • the three aforementioned documents do not describe that the piston and the cylinder containing the product to be dosed, are joined by means of a thread, which facilitates the maintenance and / or cleaning of the equipment in a quick and simple way; as well as another substantial difference is that the valve object of the present invention is simple and of reduced number of parts or parts that make up the threaded volumetric valve of a piece unlike existing valves; there is no evidence in the documents of a valve that is joined by a thread and is correctly aligned for the dosage of the product.
  • Figure 1 shows a top perspective view of the one-piece threaded volumetric valve.
  • Figure 2 shows a side view of the threaded volumetric valve of a piece.
  • Figure 3 shows a perspective view of the explosion of the threaded volumetric valve of a piece.
  • the one-piece threaded volumetric valve is formed by a piston (4) which can be pneumatic, hydraulic or electric, and which has a threaded base (9) at its front end which is fixed by fastening mechanisms (not illustrated) which may be bolts, rivet screws, presses, magnetic means and / or the combination of the foregoing; said threaded base (9) is fixed by means of the thread to a cylinder (5) in such a way that it allows the piston (4) to remain perfectly aligned with the cylinder (5) avoiding variations in the operational movement that decrease the performance of work.
  • a plunger (13) is fixed to the piston (4) by means of a copy (12) which is preferably threaded, said copying this configuration allows the plunger (13) to have a movement from one end to another inside the cylinder (5 ), and in this way perform the filling and expulsion of a solution.
  • the embolus (13) has at its periphery / at least one seal (14) which can be of the "o ring” type which is a circular ring, "chevron” type, so the seals of several lips are known, and can be Teflon, silicone, synthetic rubber, fluorinated polymer elastomer, nitrile rubber and / or the combination of the above, where Teflon is preferably used for food grade applications.
  • the cylinder (5) has a product inlet / outlet outlet (15) on the front, which is preferably a clamp-type connection and is connected by means of fastening means (11) which are preferably clamp-type clamps, to a supply valve (10), preferably of the clamp type, by means of which the product is supplied to the cylinder (5) for filling and expelling the solution, this by means of a product hopper that is installed in the upper part (not illustrated), and that, when the piston (4) is activated, retracts the plunger (13) by sucking the solution from the product hopper, the product passes through a non-return valve (16) preferably of the clamp type and which is fixed by clamping means (11), in the upper part of the supply valve (10), where, the product passes through an inlet (10a) towards the cylinder (5), once it is filled with the quantity required, the non-return valve (16) closes so that the solution passes by the outlet (10b) of the supply valve (10).
  • a supply valve (10) preferably of the clamp type
  • the piston (4) has a structure (7) installed at the rear end which can be made of aluminum, iron, steel stainless and / or the combination of the above, and is configured to fix a guide (2) on its back through which a rod (6) passes which is designed to install a stop (3) and a end on one end.
  • crank (1) at the opposite end this assembly allows the rod (6) to be adjusted by means of the crank (6) according to the volume required to fill in the cylinder (5), since by means of the stop ( 3) a piston stroke (8) is controlled allowing to increase or decrease the filling volume.
  • Example 1 use of the one-piece threaded volumetric valve.
  • the filling volume adjustment is made by means of the crank (1) to control the length of the piston stroke (8) by means of the rod (6)
  • a hopper or product container is installed in the upper part of the non-return valve (16) through which the product will pass to the inlet (10a) of the valve supply (10) that will take the product inside the cylinder (5) once the piston (4) is operated, which will retract the plunger (13), once the cylinder (5) is loaded, said piston will move forward to eject the solution through the outlet (10b) of the supply valve (10).
