Abstract

A 45° angle valve with internal/external closure and manual actuation comprises a main body formed by a valve with a single cast receiving body which projects internally, forming a communicating chamber with an outlet positioned at an angle of 45° relative to the centre and an inlet aligned with the centre, to which body a seat is externally coupled and attached to a 45° adapter positioned opposite the outlet, while internally the chamber has a chromium closing and grinding counter-seat attached to a longitudinal grinding shaft sliding through a connecting hole that is arranged at the other end of the outlet and has a diameter that abruptly increases on the outside, forming a socket accepting a square rubber ring, above which is located packing pressed into a box coupled to the collar of the receiving body, attached by screws and located in the interior of a castle; the castle has on its outside a numerical scale and a pointer, below which there is an inspection port aligned with a retainer arranged inside the castle. The side of the retainer opposite the valve has a bushing accepting the longitudinal grinding control shaft, which is attached to an actuation handle formed by transmission rods arranged equidistantly at 120° from each other, including at the top a protection nut, and the actuation handle is locked by a locking nut, while the longitudinal grinding control shaft arranged at the end opposite the counter-seat has a control wheel.

Description

"45 ° ANGLE VALVE WITH INTERNAL / EXTERNAL CLOSING AC ION ADA MANUALLY".

This patent relates to a "MANUALLY DRIVEN IN / EXTERNAL CLOSED 45 ° ANGLE VALVE", which has been designed to actuate angularly at 45 ° for better equipment maintenance through its manual opening and closing system, where the drive handle consists of 120 ° equidistant shanks allowing a perfect rotation of the longitudinal grinding camshaft.

The high pressure valves used in conductive piping, mainly of caustic mixture of bauxite pulp and lime, with high temperature for the extraction of alumina, are totally free of protective shielding, which has caused many accidents with the operators due to leakage of liquid contained in the pipeline or cleaning products when repairs are required.

Another drawback encountered in these valves is related to their system of gaskets used between the valve body, as they do not prevent the displacement of the main shaft causing a very large eccentricity between the reducer and the valve, and the current valves allow the material when stopping. penetrate the bonnet damaging this part of the pump that does not have a grinder.

Another point that should be highlighted is related to the closing and opening of the valves that is performed through a handle arranged below the steering wheel, it happens that their profiles are exactly identical, this configuration makes the handle activation difficult, since the As the operator rotates through beaters, these valves invariably align, causing accidents with the operator's hands.

Faced with this and others not mentioned drawbacks, the inventor developed the "45 ° ANGLE VALVE WITH INTERNAL / EXTERNAL CLOSURE ACTIVATED

MANUALLY "comprised of a main body formed from a valve, is comprised of a fused single receiver body that internally projects a communicating chamber with a 45 ° outlet from the center and a center aligned inlet, where an external seat is coupled. while internally provided with a chrome locking and grinding counter seat, it is fixed to a longitudinal grinding axis which slides through the connecting hole disposed at the opposite end of the outlet, and the connecting hole externally has its diameter abruptly increased. forming a cavity for packing a square rubber ring, above which are compressed gaskets through a prime gasket, which is packaged inside a bonnet which is coupled to the collar of the receiving body and fixed by screws, being the castle externally provided with a numeric scale with a marker pointer below which There is a tilting inspection door which is aligned with a retainer internally disposed in said bonnet whose opposite end of the valve incorporates a bushing that holds said longitudinal-grinding camshaft, which is fixed to a drive handle formed by rods. 120 ° equidistant drive which incorporates from the top a protective nut fixed by bolts, the drive handle being locked by a lock nut, while the longitudinal grinding camshaft at the opposite end of the counter seat holds a steering wheel.

In order to obtain a perfect understanding of what has been developed, illustrative drawings are attached to which numerical references will be made together with a detailed description where:

Figure 1 shows a cross-sectional view of the internally closed valve and a reducer driven by an electric / hydraulic motor.

Figure 2 shows a cross-sectional view of the closed valve, internal, and a pneumatic-controlled gear unit.

Figure 3 shows a cross-sectional view of the internally closed valve and a gearbox controlled by a handwheel.

Figure 4 shows a front view of the valve with internal closure.

Figure 5 shows a cross-sectional view of the externally closed valve and a gearbox controlled by a handwheel.

As the drawings and their details show, we can see that the "MANUALLY ACTIVATED INTERNAL / EXTERNAL CLOSURE 45 ° ANGLE VALVE" characterized by a main body (1) formed from a valve (2), which consists of a body single fused receiver (3) which internally projects a communicating chamber (4) with an outlet (5) at 45 ° from the center and a center-aligned inlet (6), where an external chrome seat (7) is coupled while internally it is provided with a chrome locking and grinding counter seat (8), which is fixed to a longitudinal grinding axis (9) which slides through the connection hole (10) disposed at the opposite end of the outlet (6), whereby the connecting hole (10) externally has its diameter abruptly enlarged forming a conveying cavity (11) for packing a ring of square rubber (12), above which gaskets (13) are compressed through a gasket (14), it is packed inside a bonnet (15) which is coupled to the collar (16) of the receiving body (3) and fixed by bolts (17), the bonnet (15) being externally provided with a numerical scale (18) with marker pointer (19) below which a tilt inspection door (20) is aligned with a retainer (21) internally disposed in said bonnet (15) whose opposite end to the valve (2) incorporates a bushing (22) that holds said longitudinal grinding camshaft (9), which is attached to a drive handle (23) formed by conduction rods (24) equidistantly arranged at 120 °, which incorporates from the top a protective nut (25) fixed by screws (26). the drive handle (23) being locked by a locking nut (27), while the longitudinal grinding camshaft (9) at the opposite end to the counter seat (8) has a steering wheel (28).

Based on what is described and illustrated, it is clear that the "45 ° ANGLE VALVE WITH INTERNAL / EXTERNAL CLOSURE COUPLED TO A BLOCKED REDUCER DRIVED THROUGH CROWN AND HYDRAULIC MOTOR CONTROLLED WITH SUPPORT PNEUMATIC SUPPORT It features a unique fused receiver body with 45 ° output while the inlet is center-aligned, and a revolutionary bonnet system that internally incorporates a retainer housed below the gaskets that maintains the concentricity of the grinding longitudinal axis as well as prevent the passage of material from the receiving body into the bonnet, so the operator can work safely once the packing compartment is reached through the inspection and there is no need to disassemble the equipment for exchange.

Entering a scale enables the operator to know with certainty whether the valve is open or closed, as the pointer positioned over a high number indicates that it is open and over the number zero that it is closed, This practice provides greater safety in equipment maintenance.

Another very important factor is the bonnet shield and the lubrication of the grinding longitudinal axis that prevent products from accumulating inside, which allows the shaft handling after maintenance without. any change.

All this combined with a manually operated opening and closing system via a handwheel and a drive handle that features a new arrangement where the driving rods are arranged equidistantly at 120 °, allowing them to rotate through beaters facilitating drive without causing accidents due to its configuration that does not allow alignment with the steering wheel.

Another great advantage found in the equipment is related to the seat and counter seat, which are made of chrome steel CR 40 and induction hardened, this treatment allows them to be reused and tempered again without losing their mechanical characteristics, and also against seat positioned inside the chamber so that it does not obstruct the passage of material.

It is also worth remembering that the actuation of the lock nut allows the longitudinal axis to turn crazy, facilitating the internal manual grinding of the valve to remove the embedded material inside and, consequently, reducing the physical effort of the operator, for example. It fits perfectly within the criteria that define the patent for invention. The following are their claims.
