Air switch and filter combination

An air switch comprises a switch body having a recess thereon and a switching member having an output connection port. The recess is connected to vacuum and pressure outlets through passages in the switch body. The vacuum passage is connected to a port on the wall of the recess while the pressure passage is connected to a partially circularly extending channel on the recess wall. The switching member is rotatably received in the recess and includes a radially extending channel on its inner wall. Positioning of the switching member in the vacuum or pressure modes places the member channel in fluid communication with either the vacuum port or the channel on the recess wall. When in the vacuum mode, the pressure channel is vented to the atmosphere and when in the pressure mode, the vacuum is similarly vented. When in the minimum pressure mode, a portion of the pressure is vented to the atmosphere although this pressure venting is reduced to zero when the switching member is in the maximum pressure mode. In a preferred construction, the switch is operable only when a vacuum filter connects the source of vacuum to the switch body.

1488705 Valves IMPERIAL CHEMICAL INDUSTRIES Ltd 23 May 1975 [25 June 1974] 28099/74 Heading F2V In a valve, particularly for laboratory glassware, the valve member comprises a mandrel 11 around which are placed 0-ring seals 12, 13, 14, 15 located in grooves and the whole is enclosed in a plastics sleeve 16. The O-rings press the sleeve into sealing contact with the bore 5 and the spaces between form passageways through which a port 2 may be connected with a port 3 or 4 when the valve member is moved axially by rotating a cap 17. In another embodiment, Fig. 2 (not shown), the 0-rings 13, 14 are replaced by a single O- ring (23) placed obliquely around the mandrel. In this embodiment flow is controlled by rotating the valve member by a cap as in Fig. 1. The small axial movement of the valve member is insufficient to affect flow. In a further embodiment, Fig. 3 (not shown), generally similar to that of Fig. 2, only a short length of the cap and valve body are screw threaded and on assembly the cap is screwed to a point at which the threads dis-engage so that on rotation there is no axial movement of the valve member. In a yet further embodiment, Fig. 4 (not shown), for a simple two-way valve similar to that of Fig. 1, the cap is a sliding fit on the body and is operated by push/pull. In all the embodiments the O-rings may be of rubber and the sleeves of polyethylene, nylon, a fluorine-containing polymer such as PTFE, heat-shrinkable polypropylene or heat-shrinkable tetrafluorethylenehexafluoropropylene copolymers. The thickness of the sleeve is preferably at least 0À3 mm. and not more than 0À63 mm. The body may be made of glass or rigid thermoplastic material, reinforced, e.g. with glass fibres.

Plug valve

1488706 Valves IMPERIAL CHEMICAL INDUSTRIES Ltd 23 May 1975 [25 June 1974] 28100/74 Heading F2V In a valve, particularly for laboratory glass ware, the valve member comprises a mandrel 31 around which is placed a plastics sleeve 34 having ridges 35 overlying rubber inserts 32 which help to press the ridges into sealing contact with a bore in a valve body 41. Annular grooves 33 provide a key for the sleeve which is moulded on to the mandrel. The spaces between the ridges form passageways through which a port 44 may be connected with a port 42 or 43 when the valve member is moved axially by rotating a cap 45. In another embodiment, Fig. 3 (not shown), the two middle ridges of Figs. 1 and 2 are replaced by a single ridge (64) placed obliquely around the mandrel. Flow is controlled by rotating the valve member by a cap (56) which does not transmit axial movement to the member. In a further embodiment, Fig. 4 (not shown), for a simple two-way valve, similar to that of Fig. 2, the cap is a sliding fit on the body and is operated by push/pull. In a yet further embodiment, Fig. 5 (not shown), for a straight-through two-way valve, there are two circumferential ridges, one on each side of the aligned ports, and flow is controlled by two axially arranged ridges joining the circumferential ridges. These axial ridges are so spaced circumferentially that flow is controlled by rotating the valve member. In all the embodiments, the sleeve may be of PTFE, polyethylene, nylon, polypropylene or tetrafluorethylene - hexafluoropropylene copolymers. The body may be made of glass or rigid thermoplastic material reinforced, e.g. with glass fibres. The free diameter of the valve member may be about 0À015 inch greater than the bore diameter.

本发明涉及用于高效液相色谱分析法的高压控制阀，该高压控制阀包括定子(112)，在该定子中设计有多个端口(118)(或许在此有误解：图1和3的118不对应于图3的118)，每个端口(118)均由一个通道构成，该通道在一端与各自一个端口连接件相连并且在另一端在定子(112)的定子端面(114)上具有预定的端口开口横截面(116)，所述高压控制阀还包括转子(106)，该转子具有与定子端面(114)相互作用的转子端面(110)，并且在转子端面中具有至少一个或多个凹槽(108)，所述凹槽根据转子(106)相对于定子(112)的转动位置在至少一个预定的操作位置上(这是一种限制，MBB技术在一个特定位置连接3个端口)以压力密闭的方式连接两个预定的端口开口横截面(116)，其中所述转子(106)和定子(112)在端口开口横截面(116)和凹槽(108)之外的区域内借助转子端面(110)和定子端面(114)彼此以密封的方式挤压。根据本发明，转子(106)和定子(112)至少在转子端面(110)和定子端面(114)的区域内由坚硬材料尤其是金属、玻璃或陶瓷构成。而且，转子(106)或与该转子(106)连接且包括转子端面(110)的构件安装成使得其能相对于定子(112)摆动和倾转(安装成使得其能相对于转动轴线摆动，以便在操作时始终以平面方式且以恒定的表面压力抵接定子表面)。可选地，定子(112)或与该定子(112)连接且包括定子端面(114)的构件(112b)也能安装成使得其能相对于(106)摆动或倾转(如上所述但相反)。

Two-shutter valve

A valve including a body that defines first and second ducts that open out into a third duct. The first duct is provided with a first shutter and the second duct is provided with a second shutter connected to drive means arranged to move the shutters in a normal mode of operation in which the second shutter is in the closed position and the first shutter is adjustable in position between an open position and a first closed position, a stop mode in which the second shutter is in its closed position and the first shutter is in its first closed position, and a secondary mode of operation in which the second shutter is in its open position and the first shutter is in a second closed position.

Multi-track rotary valve in combination with a pressure reducer and method for operating the combination

A method for operating a multi-track rotary valve having plural tracks for the separate introduction to vessels of at least 3 feed streams and the separate recovery from the vessels of at least 3 product streams and for simultaneous change of the flow paths of the streams. At least one stream is selected and maintained at lower pressure than the other streams so that any leakage flows from the other streams to the at least one selected stream.
