Description

(54) ПРЕДОХРАНИТЕЛЬНЫЙ КЛАПАН(54) SAFETY VALVE

водитс  настройка клапана на заданные пределы изменени  давлени  срабатывани .The valve is adjusted to the specified limits of the pressure response.

Предохранительный клапан работает следующим образом.The safety valve operates as follows.

При подаче в полость 11 управл ю ,щего давлени  поршень 7 управлени  настройкой перемещаетс  до упора во внутренний выступ гильзы 12, сжима  настроечную пружину 6. При этом давление рабочей жидкости, необходимое дл  срабатывани  предохранительного клапана, будет соответствовать усилию настроечной пружины 6, сжатой управл ющим давлением.When a control pressure is supplied to the cavity 11, the tuning control piston 7 moves up to the stop in the inner protrusion of the sleeve 12, compressing the tuning spring 6. In this case, the pressure of the working fluid required to operate the safety valve will correspond to the force of the tuning spring 6 compressed by the control pressure.

Под этим давлением рабоча  жидкость , переместив запорный орган 2, будет перетекать из полости 10 в полость 8 и далее на слив.Under this pressure, the working fluid, moving the closure body 2, will flow from the cavity 10 into the cavity 8 and further to the drain.

В том случае,, когда управл ющее давление не подаетс  в полость 11, поршень 7 находитс  в другом крайнем положении, упира сь в торец регулировочного винта 13, т.е. сжатие настроечной пружины 6 будет меньшш, а следовательно, и давление рабочей жидкости, требуемое дл  срабатывани  клапана, будет меньше.In the event that when the control pressure is not supplied to the cavity 11, the piston 7 is in a different extreme position, resting against the end of the adjusting screw 13, i.e. the compression of the adjusting spring 6 will be lower, and hence the pressure of the working fluid required to actuate the valve will be less.
