Abstract
The utility model relates to an integrated tee joint with a check valve. The integrated tee joint with the check valve comprises a tee joint pipe body and the check valve which is arranged at a joint end of the tee joint pipe body, wherein the check valve consists of a guiding plate, a valve rod, a spring, a valve plate, a sealing ring and a sealing press plate, a valve body of the check valve and the tee joint pipe body are integrated, a valve cavity outlet of the check valve is connected with one joint of the tee joint pipe body, a valve cavity inlet of the check valve is used for tightly pressing the sealing ring and a stepped hole plane of a cavity wall through the sealing press plate, and the valve plate is used for tightly pressing the sealing ring through the spring, so that holes in the sealing press plate are normally sealed. The integrated tee joint disclosed by the utility model has the beneficial effects that the check valve and the tee joint are integrated, the structure is compact, the components are fewer, the raw materials are saved, installation links are avoided, the reliability of the sealing performance is improved, and the volume space of a water feeding pump room is also effectively contracted.
Description
Technical field
The utility model relates to the fire water supply equipment technical field, is specially in a kind of fire-fighting pump-feeding room pipe the disjunctor threeway with safety check.
Background technique
The fire supply pump house is the important water supply equipment that modern high-rise building provides fire-fighting water.Fire water pump and stand by pump are connected between fire protection pipeline and pond with parallel form in the fire supply pump house, during emergency repair, and fire water pump work, stand by pump is ready, in case fire water pump breaks down, enables immediately stand by pump.In order to prevent that one while pumping water, current are from another pump line road refluence back pool, therefore safety check is installed respectively so that current are implemented to unidirectional control on the water outlet pipeline of two pumps.As everyone knows, the equipment of speedily carrying out rescue work has the characteristic of " maintain an army for a thousand days use military forces for the moment ", to the normality maintenance in fire-fighting pump-feeding room, is therefore necessary act equally, wherein to fire water pump and stand by pump serviceable condition with machine testing, be exactly one of important inspection project.For the ease of detecting, in the pipe-line system of fire supply pump house, be specially provided with for detection of by-pass line, it is realized by the three-way union that is separately positioned on fire water pump and stand by pump top, an interface of this three-way union connects the water outlet of pump, an interface connects safety check, and another one interface connecting bypass detects pipeline.In the pipeline of existing feedwater pump house, safety check and threeway are two separate control units and pipe connector, between them, are connected in series by fastening piece, Sealing, thereby belong to the package assembly of loose shape.Not only component are various, the fastening piece consumption large for this structure, trouble is installed, and the sealability of installing between junction surface is unreliable, coaxality is installed and can not get abundant assurance, also the volumetric spaces of invisible gaining water-supplying pump house.
Summary of the invention
The purpose of this utility model is to provide a kind of threeway of disjunctor with safety check, makes up the technical deficiency of existing safety check and threeway assembly and connection structure.
To achieve these goals, the utility model Bian gets following technological scheme and implements: a kind of threeway of disjunctor with safety check, comprise threeway body and the safety check that is arranged on threeway body one interface end, safety check is comprised of positioning disk, valve rod, spring, valve plate, seal ring, sealing clamp, and the setting circumference of positioning disk is provided with a plurality of axial holes; Valve rod and valve plate are connected as a single entity, and it is characterized in that:
The valve body of described safety check and threeway body are linking body structure, its valve pocket outlet is joined with the interface in the threeway body, and the valve pocket import realizes the normality sealing by the step hole plane on sealing clamp compression seal circle and chamber wall and valve plate by the hole on seal ring shutoff sealing clamp;
Described spring is nested with in the valve rod outside, and valve rod penetrates in the pilot hole in positioning disk, makes spring one end against valve plate, and the other end is against positioning disk.
Useful contribution of the present utility model is: safety check and threeway is integrated, and not only component save material less, and have removed fixing link, have increased the reliability of sealability, have also effectively concentrated the volumetric spaces of feedwater pump house.
Therefore, the utlity model has the advantages such as reasonable in design, compact structure, easy for installation, good airproof performance, pump house volume be little.
The accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
In accompanying drawing 1: 1 threeway body, 2 safety check, 201 positioning disks, 202 valve rods, 203 springs, 204 sealing clamps, 205 seal rings, 206 valve plates.
Embodiment
As shown in Figure 1, the utility model comprises threeway body 1 and is arranged on the safety check 2 of threeway body 1 one interface end, safety check 2 is comprised of positioning disk 201, valve rod 202, spring 203, valve plate 206, seal ring 205, sealing clamp 204, and the setting circumference of positioning disk 201 is provided with a plurality of axial holes; Valve rod 202 and valve plate 206 are connected as a single entity, the valve body of safety check 2 and threeway body 1 are linking body structure, its valve pocket outlet is joined with the interface in threeway body 1, and the valve pocket import realizes the normality sealing by the step hole plane on sealing clamp 204 compression seal circles 205 and chamber wall and valve plate 206 by the hole on seal ring 205 shutoff sealing clamps 204; Spring 203 is nested with in valve rod 202 outsides, and valve rod 202 penetrates in the pilot hole in positioning disk 201, makes spring 203 1 ends against valve plate 206, and the other end is against positioning disk 201.
The utility model is arranged on safety check 2 interface end of threeway body 1, and the valve body of safety check 2 and threeway body 1 are designed to linking body structure, not only component save material less, and removed fixing link, increase the reliability of sealability, also effectively concentrated the volumetric spaces of feedwater pump house.
