FIELD: agricultural engineering. SUBSTANCE: bearing bracket 2, seat insert 3 and guide members 8 of gate valve 1 are reliably clamped by means of spring members 4 on milking line 5. Spring members act onto guide members 8 first support points 9 of which rest on seat insert 3 and second support points 10, on hose attachment part 11 which can be fitted in seat insert 3. Owing to correct selection of points of application of spring member forces and position of support points 9 and 10 high clamping forces can be built to secure seat insert 3 and bearing bracket 2 on milking line 5. Hose attachment part 11 is exposed to reduced sealing forces with no influence on manufacturing and wear tolerances. EFFECT: improved reliability of operation. 6 cl, 3 dwg |
