Description
клапана обеспечивает нормальное положение запорного органа, т. е. открытое.the valve ensures the normal position of the valve, i.e. open.
При заполнении оросительной сети вода из корпуса 1 противоударного клапана через отсечное устройство поступает в баллон 5, происходит зар дка противоударного «лапана. Пока давление в сети еще мало, отсечное устройство открыто на большее проходное сечение , и происходит быстрое заполнение баллона . С посто нным увеличением давлени в сети увеличиваетс давление на поршень И (фиг. 2), и запорный орган 12, перемеша сь, уменьшает проходное сечение. Так происходит автоматическа настройка противоударного клапана на давление в оросительной сети со временем, обеспечивающим наименьший выброс воды при зар дке.When the irrigation network is filled, water from the case 1 of the shockproof valve enters the cylinder 5 through a shutoff device, and the shockproof valve is charged. While the pressure in the network is still low, the shut-off device is open to a larger flow area, and the cylinder is quickly filled. With a constant increase in the pressure in the network, the pressure on the piston AND (Fig. 2) increases, and the valve body 12, mixing, reduces the flow area. This is the automatic adjustment of the shock-proof valve to the pressure in the irrigation network over time, ensuring the lowest water discharge during charging.
При резком повышении давлени в оросительной сети противоударный клапан срабатывает .With a sharp increase in pressure in the irrigation network, the shockproof valve is activated.
При постепенном увеличении давлени сверх предельного рабочего поршень 11 преодолевает сопротивление пружины 14 и полностью закрывает проходное сечение, происходит сброс избыточного давлени , так как давление в баллоне 5 больше не повышаетс . Измен жесткость пружины 14 при помоши тарированного винта 15, можно измен ть предельное рабочее давление в оросительном трубопроводе .With a gradual increase in pressure over the limit of the working piston 11 overcomes the resistance of the spring 14 and completely closes the flow area, the excess pressure is released, as the pressure in the cylinder 5 does not increase. By varying the stiffness of the spring 14 with the aid of the calibrated screw 15, it is possible to vary the limiting working pressure in the irrigation pipe.
Предлагаема конструкци позвол ет улучшить качественные характеристики самонастраивающегос противоударного клапана на различных рел :имах.The proposed design allows to improve the quality characteristics of the self-adjusting shock-proof valve on various relays.
