Problems solved by technology

[0008] There is another disadvantage in the manufacture of housings designed to accommodate elastic rings
Such a housing has a geometry that matches that of the elastic ring and is therefore particularly complex to manufacture, especially if the ring has a polygonal cross-section

Embodiment Construction

[0029] figure 1 Shown is a gate valve 1 comprising a sealing assembly according to the invention. The valve 1 is intended to be mounted on a fluid conduit and comprises a body 20 delimiting a housing housing the shutter 10 . According to principles known per se, the shutter 10 is correspondingly movable between an open position and a closed position to allow flow Q to pass between the inlet section 20A and the outlet section 20B delimited by the body 20 or Fail.

[0030] According to the present invention, figure 1 The valve 1 shown in includes a first sealing assembly 101 and a second sealing assembly 102 operable to achieve a fluid seal on opposite sides L1 , L2 of the shutter 10 . To this end, a first sealing assembly 101 and a second sealing assembly 102 are operatively mounted respectively upstream and downstream of the shutter 10 with respect to a flow direction 200 defined by the body 20 of the valve 1 .

[0031] shown as an example only figure 1 In the preferred e...

Abstract

The present invention relates to a sealing assembly for an industrial gate valve and a valve comprising such sealing assembly. The present invention relates to industrial gate type sealing valves forlow and high pressure. In particular, the present invention relates to a sealing assembly and to a gate valve comprising such an improved sealing assembly. The sealing assembly ensures excellent sealing performance at low and high pressures by exclusively using thermoplastic material sealing elements, completely eliminating the drawbacks which afflict the sealing systems of known type, in particular in relation to the reliability of the sealing elements made of elastomeric material.

Description

technical field [0001] The invention relates to the manufacturing field of industrial gate valves. In particular, the present invention relates to a seal assembly for a gate valve. The invention also relates to an industrial valve comprising at least one first sealing assembly according to the invention. Background technique [0002] In general, a gate valve includes at least one body and at least one gate shutter, also referred to as a slab. The valve body defines a cavity for the passage of fluid between the inlet section and the outlet section. The shutter is usually preferably moved by a mechanical actuator between a closed position in which the shutter prevents fluid from reaching said outlet section and an open position in which the inlet and outlet sections are in communication . The gate valve also includes a seal assembly interposed between the valve body and the shutter to achieve a fluid seal when the shutter is in the aforementioned open position. [0003] T...
