Abstract

The utility model relates to the technical field of manufacture of ventilation pipe fittings in building pipelines, and in particular relates to a rectangular isometric non-return tee joint with an overturning plate. The rectangular isometric non-return tee joint comprises a tee joint shell 1, baffles 2, a main shaft 3 and an overturning plate 4, and is characterized in that the sizes of openings of branching pipes of the tee joint shell 1 are the same, the main shaft 3 is arranged at an included angle of the branching pipes in the tee joint shell1, the overturning plate 4 is arranged on the main shaft 3 and can rotate around the center of the main shaft, and the baffles are respectively arranged at the ends of the branching pipes of the tee joint shell 1. Compared with the prior art, the rectangular isometric non-return tee joint can prevent fluid from flowing back and also has the advantage of playing a role in reducing pressure on the valve of a front back-up system branch air pipe of the tee joint, thus protecting the equipment and being safe and reliable. For a ventilation pipeline system with relatively simple requirements, the rectangular isometric non-return tee joint can substitute for the valve of the branch air pipe, thus saving cost, being simple in manufacture and convenient to use, and having a good market prospect.

Description

The isometrical non-return threeway of a kind of side's rectangle with tipping platform

[technical field]

The utility model relates to the ventilation duct accessory manufacture technology field in architecture pipe, the specifically isometrical non-return threeway of a kind of side's rectangle with tipping platform.

[background technique]

Threeway is pipe fitting, pipe joint, is again pipe fitting threeway or tee pipe fitting, and tee union is used in main pipeline and wants the branched pipe place.Three are connected with dividing of isometrical and reducing, and the adapter end of equal tee is identical size; The supervisor of the threeway of reducing takes over measure-alike, and the adapter size of arm is less than supervisor's adapter size.Threeway is a kind of pipe fitting for the pipe branch place.

In the air pipeline system, usually to use threeway, especially, in thering is the air pipeline of standby system, often need the front standby system branch road of threeway in closed condition.In the prior art, generally adopt the mode that adds valve on the standby system arm to realize, pour in down a chimney to prevent fluid.But the effect of water conservancy diversion is only played in the threeway in this technology, and, at the valve front end of spare duct, pipeline, always in high pressure conditions, exists larger potential safety hazard, safe and reliable not.

[model utility content]

The purpose of this utility model is exactly in order to solve deficiency of the prior art and defect, and a kind of novel structure is provided, safe and reliable, can effectively prevent that fluid from refluxing and the cost-saving isometrical non-return threeway of side's rectangle with tipping platform.

The isometrical non-return threeway of a kind of side's rectangle with tipping platform, comprise three-way body 1, baffle plate 2, main shaft 3 and turnover panel 4, it is characterized in that the described three-way body 1 arm mouth of pipe is measure-alike, the interior branched pipe of three-way body 1 angle is provided with main shaft 3, establish turnover panel 4 on main shaft 3, described turnover panel 4 can rotate around the alignment of shafts, and described three-way body 1 branched pipe termination is baffled respectively.

The interior branched pipe of described three-way body 1 angle is provided with main shaft 3, in branched pipe, with respect to the main shaft opposite side, is provided with baffle plate, and turnover panel turns to the baffle plate place around the alignment of shafts to be stopped.

Compared with the existing technology, it has advantages of when preventing the fluid backflow can also play decompression to the valve on standby system branch wind pipe before threeway to the utility model, thereby plays the technique effect of having protected equipment, safe and reliable.And, for the simple air pipeline system of relative requirement, the utility model also can replace the valve of branch wind pipe to use, cost-saving, and make simply, easy to use, market prospects are good.

[embodiment]

Below in conjunction with accompanying drawing, the utility model is described in further detail, is very clearly the structure of this device and the principle people professional concerning this.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

The utility model is the isometrical non-return threeway of a kind of side's rectangle with tipping platform, comprise three-way body 1, the housing 1 arm mouth of pipe is measure-alike, the interior branched pipe of housing 1 angle is provided with main shaft 3, main shaft 3 peripheral hardware turnover panels 4, housing 1 branched pipe termination is baffled 2, and turnover panel 4 can rotate around main shaft 3, and turnover panel 4 can stop operating when main shaft 3 turns to baffle plate 2.

The isometrical non-return threeway of side's rectangle with tipping platform as shown in Figure 1, 2.When fluid, by an arm during by threeway, turnover panel 4 makes main shaft 3 rotate under the effect of hydrodynamic pressure, finally under the stopping of baffle plate 2, stops, and plays the effect that prevents that the fluid backflow from entering another arm; When contrary in fluid flow direction and Fig. 1, main shaft 3 slightly can be changed, be made main shaft 3 pass housing 1 from top, and be made into the handle of easy-to-operat, manually adjust turnover panel and cut off a certain branch road.
