Bozhko UDC 621.646.616.001.24 One can analyze a ball-seating valve containing fluoroplast seals in order to determine the design features of the parts and the conditions for assembly and use. A basic condition in assembling such a valve (Fig. 1) is that the rubber seal 3 is completely tight and the plug 1 is in contact with the seal 2 (in the closed position) for relatively low pressures in the working medium. The rubber sealing rings of circular cross section (for self-sealing) are recommended [1] to be used with a preliminary strain in the ring e ‡ e¢ , in which e¢ is dependent on the shape of the groove (e¢ = 0.025 for a rectangular groove or one simi- 0 0 0 lar to it). The minimum initial gap between the pipe 4 and the seal 2 is Δ = 0.025d, in which d is the cross sectional diameter of the rubber ring. If the seals are stored for t days before use (or until the pressure rises for a self-sealing system), it is necessary to pro-
