2.8 Brief about Invention The plastic removal valve (1) for containers for transporting and storing liquids, the valve being designed as a butterfly or ball valve, has a valve housing (2) with an inlet nozzle (7), which can be connected to the outlet nozzle (15) of a liquid container (16), and with an outlet nozzle (9), which is welded to the male part (23) of a Kamlok coupling for the connection of a removal hose. The valve housing (2) consists of a high-density polyethylene (HDPE) and the male part (23) of the Kamlok coupling consists of a glass-fibre-reinforced high-density polyethylene. The hardness of the high-density polyethylene material of the Kamlok-coupling male part (23) welded to the outlet nozzle (9) of the valve housing (2) , said hardness being produced by the mixture of glass fibres, allows an sealed connection between the removal valve (1) and an emptying hose, the connection end of which is fastened to the Kamlok-coupling female part, which is clamped firmly on the male part by means of clamping levers articulated on it.

(The most relevant patents/applications are discussed as under) :
  Application No. Summary
2.10.1  US3988000 A mechanically packed gasket is supported circularly concentric on the operator shaft of a butterfly valve in a wedged interfit with an inwardly chamfered end of the shaft journal. With gasket pressure of magnitudes greater than line pressure, leakage of gas from the valve passage past the actuator is prevented. At the same time, gasket pressure against the operator shaft prevents leakage to atmosphere of any gas content inadvertently obtaining access to the shaft surface either by leakage into the vane cavity through porosity of the vane or through functional failure of other shaft seals. Located outward of the shaft journal in a leakage path parallel to that of the gasket is a lubricant packing construction enabling in-service maintenance to be performed against the journal in the event line content leakage should be encountered there.

 

2.10.2 US4133513 A butterfly valve assembly includes a two-section housing in which a resilient liner is seated. The liner includes diagonally opposed collars, with a bushing being bonded within each collar. A gate is rotatably mounted within the liner and includes closure, stem and stub shaft portions of integral, one-piece construction. The gate is formed of plastic and includes a metallic reinforcing shaft extending completely therethrough. The closure includes bearing surfaces extending around the stem and stub shaft, and sealing surfaces extending between the bearing surfaces. The sealing and bearing surfaces are of continuous uninterrupted spherical configuration. The liner includes seating surfaces which extend between annular surfaces of each collar. The seating surfaces and the annular collar surfaces are of continuous uninterrupted spherical configuration. Flat surface portions are disposed on the bearing surfaces and extend around the stem and stub shaft portions.

 

2.10.3  US7219652 A bearing support device includes a rotor, a bearing member, and a bearing holding member. The rotor rotates about a rotation center axis. The bearing member rotatably supports the rotor within a bearing hole passing through the bearing member. The bearing holding member holds the bearing member in a secure manner within a fitting hole that passes through the bearing holding member along the center axis of the rotor via an engagement force produced by tightly fitting the bearing member. The rotor and bearing member are made of a resin. An engagement section is provided for tightly fitting the bearing member into the fitting hole relative to the bearing hole to enable an engagement force produced by the tight fitting to act in a direction that does not affect an inner diameter dimension of the bearing hole.
