Locking device

Shut-off devices are a type of pipeline valve that is an element of the level indicator. Locking devices of the level indicator are always produced in a set of two cranes – lower and upper, DN20, installed on the boiler (tank, container, vessel, reservoir) through the connection (flange, CAPC). Level indicator-a device containing a viewing glass and designed to monitor the level of liquid in closed vessels (boilers, heat exchangers, tanks for various purposes). The level indicator is a structure consisting of shut-off devices of a crane or valve type and an oil seal Assembly, through which a level indicator (for example, 12kch11bk) or a transparent glass tube is connected. The operation of the liquid level indicator is based on the principle of communicating vessels. The level of liquid coming from the working container through the locking devices to the level indicator corresponds to the level of liquid in the container.

THE SHUT-OFF DEVICE LEVEL INDICATOR 12нж13бк

12нж13бк

12nzh13bk-shut - off device of the level indicator of the valve type. The 12nzh13bk shut-off device consists of an upper fitting valve (mounted in the upper part of the container), a lower fitting valve (mounted in the lower part of the container) and a test-discharge tap (built into the lower locking device). As a level indicator, a 12kch11bk water indicator frame is usually used (at a pressure of up to 4.0 (40) MPa (kgf / cm2)) or a quartz tube with a diameter of 20 mm (at a pressure of up to 3.0 (30) MPa (kgf / cm2)). 12nzh13bk is installed on tanks, boilers for visual determination of the liquid level. The operation of the shut-off device is based on the principle of communicating vessels, so the level of liquid coming from the working container to the level indicator corresponds to the level of liquid in the container. The locking device 12nzh13bk is manufactured with a nominal diameter-DN20.

2nzh13bk1-shut-off device of the level indicator of the valve type. As a level indicator, a 12kch11bk water indicator frame is usually used (at a pressure of up to 4.0 (40) MPa (kgf / cm2)) or a quartz tube with a diameter of 20 mm (at a pressure of up to 3.0 (30) MPa (kgf / cm2)). 12nzh13bk1 is installed on tanks, boilers for visual determination of the liquid level. The operation of the shut-off device is based on the principle of communicating vessels, so the level of liquid coming from the working container to the level indicator corresponds to the level of liquid in the container. The locking device 12nzh13bk1 is manufactured with a nominal diameter of-DN20.

LOCKING DEVICE 12нж29нж

12нж29нж

12nzh29nzh locking device. The equipment is intended for equipping the level indicators of block-complex equipment when operating in open areas. The shut-off device is a set consisting of two shut-off valves UV 24004 DN 15mm with a check valve and one shut-off drain valve UV 22010 DN 6mm. The method of connecting the UV 24004 valve to the tank is flanged according to GOST 12821-80, to the level indicator-with a special flange; the UV 22010 valve to the level indicator-with a coupling. UV 22004 valves must be installed horizontally relative to the spindle axis. The valves of the shut-off device are controlled manually using handwheels. The locking device 12nzh29nzh is made with a nominal diameter of DN15.
