Description
Известны устройства дл замены обратного клапана в ремонтируемом кране газопровода, наход щегос под давлением с использованием устанавливаемого на обратном клапане кожуха и пропускаемой него отвертки. Отличительной особенностью предлагаемого устройства дл замены обратных клапанов при ремонте крана газопровода, наход щегос под давлением, вл етс то, что в нем дл перемещени кожуха применен полый шпиндель, снабженный снаружи резьбой и внутри пружиной, воздействующей на упорный дл обратного клапана niaрикоподщипник . Такое выполнение предлагаемого устройства имеет целью облегчить попадание резьбы устанавливаемого обратного клапана в резьбу щпиндел крана.Devices are known for replacing a check valve in a repaired valve of a gas pipeline, which is under pressure using a casing mounted on the check valve and a screwdriver to be passed through it. A distinctive feature of the proposed device for replacing non-return valves when repairing a gas valve that is under pressure is that it uses a hollow spindle to move the casing, which is externally threaded on the outside and acting on a spring that acts on the valve support valve. This embodiment of the proposed device is intended to facilitate the penetration of the thread of the installed check valve into the thread of the valve pin.
На фиг. 1 изображена схема устройства дл замены обратного клапана в ремонтируемом кране газопровода; на фиг. 2 - схематично изображена головка предлагаемого устройства.FIG. 1 shows a diagram of a device for replacing a check valve in a gas pipeline being repaired; in fig. 2 - schematically shows the head of the proposed device.
Корпус устройства состоит из двух соосных втулок I 2, соединенных дуговыми полосами 3, располол енными относительно друг друга под углами в 120°. Втулка / служит дл придани направлени снабженному наружной резьбой полому щпинделю 4, несущему на конце, обращенном к крану, кожух, надвигаемый на обратный клапан 5, а втулка 2 крепитс к ремонтируемому крану (на чертеже не показано).The housing of the device consists of two coaxial bushings I 2, connected by arc strips 3, which are disposed relative to each other at angles of 120 °. The sleeve / serves to give a direction to a male thread 4, supplied with an external thread, bearing on the end facing the valve, a casing pulled in by a check valve 5, and sleeve 2 is attached to the valve being repaired (not shown).
В полости щпиндел помещена спиральна пружина 6, воздействующа через тарелку 7 на щарикоподщипник 5, в который упираетс обратный клапан 5. При замене обратного клапана в ремонтируемом кране газопровода через полость шпиндел и пружину пропускают отвертку , вывертывают обратный клапан из крана и на его место устанавливают новый клапан, который при вращении щпиндел преодолевает давA coil spring 6 is inserted in the cavity of the pinch, acting through the plate 7 on the ball bearing holder 5, against which the check valve 5 abuts. a valve which, when rotating the pin of a rod, overcomes by giving
