Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to valves, and more particularly to valves having a valve body with multiple internal fluid ducts. These fluid ducts open on the same side of the valve body through orifices that can receive threaded connecting pipes.

BACKGROUND OF THE INVENTION Valves with connecting orifices are usually provided with threaded sockets, in which various types of threads (metric, BSP, NPT, etc.) are commonly used. If a valve manufacturer wishes to sell such valves in different countries, the valves can be manufactured in many models with different threads or supplied with a set of adapters. Either. This increases both the cost of the valve and the overall size of the valve.

Furthermore, due to the stress placed on the threads of the valve orifice when the connecting tube is tightened to the valve body, the synthetic materials often used for the valve body are not strong enough for the use of threads, making it difficult to replace metal threads. It is virtually essential to use it. Therefore, it would be desirable to provide a valve having a structure that solves these problems.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an improved valve having a valve body in which the threaded fluid outlet socket is located in a separate metal plate.

SUMMARY OF THE INVENTION In order to achieve this and other objects, the present invention comprises a valve body means with an internal fluid duct, the internal fluid duct being connected via an orifice to a surface of the valve body means. A valve is provided having a metal plate in contact with the valve body, the plate having a threaded fluid passage socket projecting from at least one side of the plate and aligned with the orifice.

Embodiment A valve embodying an example of the present invention is shown in FIGS. 1 to 3.
As shown in the figure. The valve has a valve body 1 made of synthetic material with a plurality of internal fluid ducts 2, each of which opens into a face 3 of the valve body 1.

A metal plate 5 is placed in contact with the surface 3 and is provided with a fluid passage socket or protrusion 6 formed by drilling a threaded hole 4. In the valve body 1,
At the duct opening of the duct 2, that is, the orifice 7,
A recess 8 is provided which is designed to receive a respective one of the projections 6. Each of these recesses 8 has an annular groove 9 in which a resilient O-ring 10 is accommodated. The O-ring 10 grips the outer surface of each of the protrusions 6, and when the plate 5 is attached to the valve body 1 and the holes 4 are aligned with each of the ducts 2, the protrusions 6 and the ducts 2
forming a fluid seal between the

The metal plate 5 is provided with a longitudinal reinforcement 11. By extending the two right-angled horizontal ribs 12 at both ends of the plate 5,
A lateral lug 13 is formed which is substantially parallel to the main plane of the plate 5. These lugs 13 are connected to two end cover plates 15
and 16, these cover plates 15 and 16 are attached to the valve body 1, thereby fixing the plate 5 thereto.

A first variant shown in FIGS. 4 and 5 uses a metal plate 17 with a threaded protrusion, which is reinforced with longitudinal ribs 27 and with valve fastening fixing bolts 18. It is firmly fixed to the base 1b of the body 1. The base 1b of the valve body 1 is configured to accommodate the rib 27. Board 1
7 does not require lugs 13 and uses holes 19 that accept fixing bolts 18. Furthermore, when the plate 17 is attached to the base 1b, the protrusion 6b faces outward from the valve body 1.

A second variant, shown in FIGS. 6 and 7, concerns valves arranged side by side. This variant uses a metal plate 24 with lugs, threaded projections and longitudinal reinforcements, which metal plate 24 is placed on the valve body of another valve or on both sides of the valve body 1. It has right angled lugs 25 designed to engage a respective one of the slots formed in the end elements.

In a valve assembly of the type shown in FIGS. 4 and 6,
The valve body 1 may consist of two parts 1a and 1b.

The configuration provided by the present invention allows the valve body to be made from synthetic materials for specific applications. Furthermore, because the coupling plate can be installed and replaced as an integral unit, adaptation to the standard threads specified in different regions of the world is very easy and at the same time it can be adapted to the required Provides a threaded connection having a length.

It will therefore be appreciated that in accordance with the present invention there is provided an improved valve having a valve body in which the threaded fluid passageway socket is provided in a separate metal plate.
