In a siphon tube (1) of a reservoir, even when a front end of tube (1) is in the vicinity of the bottom of the reservoir, there is no fear that slurries are sucked by tube (1) which: reaches the bottom of the reservoir to draw a liquid contained therein out of the reservoir is characterized by a liquid-inlet opening (3) directed normal to a longitudinal axis of tube (1) Tube (1) has its front end formed into: an inverted T-shape provided with opposite end openings in a laterally extending portion thereof, each of which openings forms the liquid-inlet opening (3); or, an L-shaped curved form a front end of which forms an opening directed normal to the longitudinal axis of tube (1); or, is closed with a cap so that an opening is disposed adjacent to an upper surface of the cap to serve as the liquid-inlet opening.

A connector comprises a synthetic resin plug 11 fitted to an opening portion 1a of a container 1 that stores a liquid, and a socket 13 for connection to the plug 11. The plug 11 comprises, a lid body 14 secured in a fluid tight manner to the opening portion 1a, a plug portion 16 provided on the lid body 14 and connectable to the socket 13, and a siphon tube 17 extending downward from a lower portion of the lid body 14 such that when the lid body 14 is secured to the opening portion 1a, a lower end is arranged near a bottom of the container 1. The siphon tube 17 comprises a tube integrally formed with the lid body 14. As a result, when the liquid inside the container 1 is drawn out, gas leakage from the siphon tube 17 can be reliably prevented, so that erroneous detection of an nullemptynull detection can be reliably prevented and the liquid completely used up.

A replaceable orifice unit is disposed outside a pressure or a flow regulator valve, and therefore easy in maintenance, requires the smallest possible number of components, is compact in construction to save space, free from any fear that fluid impurities in a fluid circuit bank up against an upstream side of an orifice piece (2) of the unit, advantageous in replacing one type of chemicals flowing through the circuit with another type, and also advantageous in manufacturing cost. The replaceable orifice unit is constructed of a tube member (1), in which the orifice piece (2) assuming two symmetrically arranged similar triangular shapes in longitudinal cross section is fixedly mounted. Formed between vertexes of the triangle shapes is an orifice (2a). An O-ring is coaxially disposed between the tube member (1) and the orifice piece (2) to prevent the fluid from passing through therebetween.

In a joint structure for coupling a first component (21) to a second component (22) in a joint portion of a fluid flow passage, the second component (22) has a portion thereof inserted into the first component (21) to engage with the first component (21). The second component (22) is provided with a flange portion (26), which is disposed adjacent to a bottom surface of the first component (21) and welded or bonded to the bottom surface, so that these components (22, 21) are coupled with each other in an easy and a fluid-tight manner in a condition in which they are prevented from rotating relative to each other without using any locking pin. There is no fear that the components (22, 21) dissolve in a fluid or gaseous material passing through the fluid flow passage. The joint structure is easy in maintenance.

A plug portion 23 which engages to a socket 13, to which a liquid transport hose and a gas transport hose 7 are connected, is provided to a plug 12 which closes an aperture portion which is formed in a container. A liquid conduit 26 on the side of the plug 12 which is communicated to a liquid conduit 56 on the side of the socket 13 is formed on the inner side of the plug portion 23, while a gas conduit 41 on the side of the plug 12 which is communicated to gas conduits 52 and 63 on the socket side is formed on the outer side of the plug portion 23. By this construction, it is possible to anticipate simplified and reduced cost manufacture for a connector which excels in convenience due to having a plurality of conduits.
