Abstract

A valve with fluid block and bleed functions has inlet parts 2, 3, 4 and an outlet part 11 as well as blocking parts 6A, 6B and bleed part 7. At least one of the blocking and bleed parts is removably connected to the remainder of the valve. At least one of the inlet and outlet parts includes a removable flange portion.

Description

Field of Invention
The invention relates to valves for use in hydraulic applications.
Background to Invention
Valves are known for use in hydraulic systems in order to control fluid flow. When there is a requirement to remove a component of the system, for instance, for maintenance purposes, the section of the system containing the component must first be isolated and secondly the pressure within the system must be safely reduced or vented. To carry out these actions, a valve with a combination of block and bleed functions is required.
Currently available valves having fluid block and bleed functions are of a one piece body construction and include a flanged inlet or outlet (or both) to connect the valve to the hydraulic system. If a different flange rating or valve combination is required, a completely new valve body must be stocked or manufactured. As a result there is a high inventory cost as well as a long lead-time because of the complexity of changing the valve.
Statement of the Invention
According to one aspect of the present invention, there is provided a valve having fluid block and bleed functions, the valve comprising inlet and outlet parts, a blocking part and a bleed part, at least one of said blocking and said bleed parts being removably connected to the remainder of the valve.
In another aspect of the present invention, there is provided a valve having fluid block and bleed functions, the valve comprising inlet and outlet parts, a blocking part and a bleed pad, at least one of the inlet and outlet pads including a removable flange portion.
Preferably the inlet part includes a removable flange.
Preferably the inlet part includes housing with which the flange is in sealing engagement, the housing being provided with an insert which retains the flange in said sealing engagement.
Preferably the housing is in sealing engagement with the bleed part.
Preferably said bleed part is in sealing engagement with a blocking part.
Preferably said inlet, said blocking part and said bleed part have aligned bores extending thereth rough.
Preferably said pads are connected together by means of elongate fasteners extending from the outlet part through intervening pads to said inlet pad.
Preferably said elongate fasteners are secured to said housing of said inlet pad.
The present invention also provides a method of modifying the functionality of a valve in accordance with the present invention, the method including removing one of said pads from the valve and replacing it with another such part compatible with the valve.
Brief Description of Drawings
The accompanying drawings are as follows:-Figure 1 illustrates a first embodiment in accordance with the present invention; Figure 2 illustrates a second embodiment in accordance with the present invention; and Figure 3 illustrates the third embodiment in accordance with the present invention.
Detailed Description of the invention
The present invention will be described, by way of examples only, with reference to the accompanying drawings.
Referring to Figurel of the accompanying drawings, there is illustrated a valve 1 having a double block and bleed functionality. The valve is provided with a flange 2 which, in use, is sealed to a hydraulic system by, for instance, a gasket (not shown). Flange 2 is provided with holes 13 which can be utilised to firmly attach the valve to the hydraulic system.
Flange 2 forms pad of an inlet of which the other major components are a housing 4 and an insert 3. Insert 3 acts to retain the flange by means of a shoulder portion 3A engaging with a corresponding stepped portion of the flange. Insert 3 is retained within housing 4 by means threaded portions 4B provided on these components.
Insert 3 includes an internal hexagonal feature in its bore which is used to rotate the insert and thereby to firmly retain the flange in position.
A dowel pin 5, located in flange 2, locates in housing 4 and prevents rotation therebetween.
Valve 1 includes a blocking part 6A located adjacent the inner face of the inlet. Blocking part 6A is in the form of a ball valve module which locates radially on the insert, the insert housing carrying an 0-ring 6B which provides sealing engagement with module 6A. Ball valve module 6A houses a ball 8 and seals 9 and functions as a conventional ball valve.
Located adjacent ball valve module 6A is a needle valve module 7 which locates radially on module 6A, the latter being provided with an 0-ring 6A which provides sealing engagement between module 6A and module 7.
Needle valve module 7 incorporates a needle valve 10 which can be closed down on a radial hole extending perpendicularly from the central bore of the valve. A cross drilled hole joins said radial hole to a further radial hole spaced at 900 circumferentially from said first mentioned hole.
Located adjacent needle valve module 7, on the opposite side to ball valve module 6A, is a further ball valve module 6B. Located adjacent to further ball valve module SB, on the opposite side to needle valve module 7, is a top plate 11. Top plate 11 is provided with bolts 12 which extend through said top plate 11, ball valve modules 6A and 6B, needle valve module 7 and engage in screw threads in housing 4.
Top plate 11 forms the outlet to the valve and incorporates a threaded section 1 1A to enable the valve to be connected to the hydraulic system.
Referring to Figure 2 of the accompanying drawings, a valve 14 is similar to the valve shown in Figure 1 except that one of the ball valve modules is not present. The valve of Figure 2 has a single block and bleed functionality.
Referring to Figure 3 of the accompanying drawing, a valve 15 according to the present invention is similar to that described above in relation to the valve of Figure 1, that is to say, it has a double block and bleed functionality. The valve of Figure 3 differs from that of Figure 1 only in that the flange 16 replaces flange 2, flange 16 having a different pressure rating and or being of different dimensions.
