Definitions

  • the present invention relates to fluid a shut-off valve, and to the method for its production.
  • the on/off type being a valve able to intercept fluid by rotating the valving element from its open to its closed position through an angle generally of 90°.
  • intermediate positions are not used, as the form of the valving element, together with the internal profile of the valve, do not enable the flow rate to be proportioned on the basis of the rotation of the valving element.
  • Ball and tapered plug valves are of this type. An example of these valves is described in US 3,687,416.
  • valves use a valving element symmetrical about its axis of rotation.
  • An object of the present invention is to provide a valve, in particular of the tapered plug type, which has better characteristics than those of the known art. Another object is to prevent liquid stagnation within the valve interior. Another object is to reduce the operating torque required to open and close the valve.
  • a fluid shut-off valve comprising a valve body and a control element for said valve rotatable within said body in order to control the flow of said fluid, characterised in that said control element includes a C-shaped recess such as to present only an upper horizontal first portion connected to a vertical lateral second portion which is connected in its turn to a lower horizontal third portion.
  • valve formed from only two parts, consisting of a valve body and a control element for said valve, in accordance with claim 1.
  • a process for producing a valve in accordance with claim 1 characterised by comprising a stage of forming an inner rigid plastic core of said control element and a stage of co-moulding said control element with an elastic plastic material.
  • the present invention provides a valve, defined as a curtain valve, in which the control element used to intercept the fluid is of a shape not symmetrical about its axis of rotation.. It hence ensures that fluid
  • FIG 3 is a front view of the valve valving element;
  • Figure 4 is a side view of the valve valving element.
  • a valve according to the present invention consists of two parts: a valving element 1 , or valve control element, and a valve body 2.
  • the valve body 2 presents an inlet connector 3, an outlet connector 4, and a seat in which the valving element 1 is positioned. It also comprises a stop 6.
  • the valving element 1 comprises upperly an operating handgrip 7,
  • the handgrip 7 includes suitable means (an internal recess) to cooperate with the stop 6 such that the valving element can rotate only through 90°, to open and close the valve.
  • the structure 9 has a C-shaped lateral recess such that it presents an upper horizontal first portion 11 lying below the series of
  • the first portion 11 is connected laterally to a vertical lateral second portion 12, connected in its turn to a lower horizontal third portion 13.
  • the cone frustum 8 hence presents an empty space 14, defined by the portions 11 -13, to allow fluid passage, and has only one shoulder 12: the corresponding shoulder symmetrical
  • the lower horizontal third portion 13 presents a slight inclination towards the mouth of the C, i.e. it has a greater thickness in the region in which it is connected to the second portion 12 than at its opposite end.
  • the first portion 11 has a greater thickness in the region in which it is connected to the second portion 12 than at its opposite end.
  • the inclination of the third portion 13 enables the fluid to flow out when the valving element 1 is in its closed position, so preventing liquid stagnation in its interior.
  • the series of projections 9 comprises a first projection 20 or lip having an overlying first diameter and an underlying second diameter, the overlying first diameter being greater than the underlying second diameter.
  • the first projection 20 is arranged to cooperate with a recess 21 positioned above the seat 5, and having a diameter slightly greater than said overlying first diameter of the first projection 20.
  • the series of projections 9 comprises a second and a third projection 22 separated from each other by a recess 23.
  • the projection 22 and the recess 23 ensure upward fluid tightness.
  • the dimensions of the valving element 1 and body 2 are such as to ensure an interference fit, to maintain the valve sealed. According to the present invention, those surfaces of the valving element 1 which are in contact with the body 2 are very reduced because of the C-shaped lateral recess, and are such as to ensure
  • a projection 20 is used cooperating with the recess 21.
  • a common split ring can be used.
  • the dimensions of the valving element are such as to ensure a dead seal angle of not less than 15°, the "dead angle" being defined as that portion of rotation within which the valve, when in its closed position, interrupts flow without any seepage.
  • the action of the fluid pressure is exerted on the surface of the valving element defined by the surfaces 11 -13, hence, if the valving element is constructed of a plastic/elastic material, the deformation of the valving element facilitates and improves the valve seal, which is already provided by the interference fit between the valving element and the valve body.
  • the preferred material for construction of the valving element is a
  • the many such materials include ABS, polyurethane, nylon, polypropylene, hostaform, PTFE, acetal resins.
  • the exterior of the valving element 1 with the exception of the aforespecified, and also including the second and third projection 22, is covered with a layer 31 of elastic and/or rubbery material.
  • the many usable materials include: HNBR rubber, NBR rubber, fluorinated rubber, santoprene, soft polyurethane.
  • the preferred material for the valve body 2 is metal of brass, bronze, steel or cast iron type, or plastic.
  • valve consists of two main components, independently of the material chosen for forming these components. This is because of the shape of the valving element 1 and of that of its housing within the valve body 2.
  • the valving element 1 is formed of thermoplastic material, it consists of a core formed of rigid load-bearing material, and an outer conical sealing shell of soft thermoplastic material. These two materials are moulded and rigidly joined together by hot co-moulding (multi-injection) such as to form a single piece.
  • the material chosen to form the valve body can be metal or plastic; if plastic materials are chosen, these must be sufficiently rigid. If the
  • valving element 1 and the valve body 2 are formed of metal, a precise fit for the surfaces must be chosen, however if the valve body is formed of plastic/elastic material and the valving element of metal, the fit must be an interference fit.
  • thermoplastic materials for forming the components makes the valve totally recyclable, it being possible to replace the valving element if damaged.
