Abstract

The utility model discloses a three-way joint of a branch pipe with a cut-off valve, which belongs to a fixture of a civil architecture pipeline or an agricultural irrigation pipe passage and is composed of a main pipe and a branch pipe, wherein the main pipe and the branch pipe are mutually matched and connected. The utility model is characterized in that the branch pipe is provided with the cut-off valve directly, and the caliber of the branch pipe of the three-way joint can be the same as the caliber of the main pipe or can be different from the caliber of the main pipe. The utility model has the advantages that design is simple and slickness, the size of water supply quantity can be adjusted flexibly according to a water need rule, purposes of water saving, energy saving and material saving are achieved really, pipeline design is simplified and investment in pipeline laying technology is saved.

Description

Prop up the tee union of pipe racks block valve

Technical field

The utility model belongs to a kind of water supply line accessory, especially a kind of branch pipe tee connection link.

Background technique

The feed piping development is swift and violent, but various pipe fitting joint all separates with block valve; Water saving is a new technology, especially in the industrialized agriculture water-saving irrigation, major part still is broad irrigation, and agricultural irrigation conduit is a lot, and particularly the always just simple threeway of droping irrigating pipe or four-way come branch, it is simple and crude to agricultural irrigation conduit is arranged, discharge water simultaneously during irrigation, can not be according to the crop law of needing the water, free adjusting water output size, take their own roads, wasted power, material resources and water resources.

Summary of the invention

The purpose of this utility model provides the tee union of a kind of pipe racks block valve, reduce pipe fitting joint and separated the combination cost that brings with block valve, having solved especially can be according to law of needing the water, free adjusting water output size reaches water saving, energy-conservation, the pipe laying technology of saving material and reducing investment outlay really.

The tee union that the purpose of this utility model is achieved in that a pipe racks block valve is by being responsible for and arm is formed, and the person in charge and arm are kissed mutually and connect, and directly arm is provided with cut-off valve; The arm bore of tee union be responsible for can adopt identical or inequality.

The utility model directly is provided with cut-off valve on arm, simplicity of design and ingenious, can simplify piping, construction, use, change and repair are conveniently, reduce manpower, save water resources, have free adjusting water output size, soil moisture is remained in the optimum plant growth scope, help improving the yield and quality of crop.Can science, rationally use water resources, the purpose of reach significant water saving, energy-conservation, saving of labor, increasing production, increase income.

The figure explanation

Accompanying drawing 1 is the tee union structural representation of a pipe racks block valve:

Accompanying drawing 2 is the stem structure schematic representation of a pipe racks block valve;

The threeway agent structure schematic representation of 3 pipe racks block valves of accompanying drawing.

Accompanying drawing acceptance of the bid keep the score state as follows:

1---be responsible for; 2---arm; 3---block valve: 4---valve rod; 5---valve gap; 6---axial sealing ring; 7---radial direction seal ring; 8---handgrip; 9---locker; 10---the internal thread buckle; 11---the circular cone seal cartridge; 12---the riffled tube straight coupling; 13---through flow hole.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

The tee union of a pipe racks block valve as shown in Figure 1 is made up of the person in charge 1 and arm 2, and the person in charge 1 connects with arm 2 kisses, at arm 1 and the person in charge's 2 engagements cut-off valve 3 is set directly, and arm 2 bores of tee union can be identical or inequality with the person in charge 1.

Embodiment one: the cut-off valve 3 that directly is provided with at arm 1 and the person in charge's 2 engagements adopts ball valves, the spool of ball valve adopts column type valve rod 4, valve rod 4 upper ends are handgrip 8, handgrip 8 belows are valve gap 5, establish locker 9 at the edge of valve gap 5, be provided with the radial direction seal ring 7 more than at least one below valve gap 5, the through flow hole 13 that passes valve rod 4 is established in valve rod 4 lower ends, is provided with symmetrical a pair of axial sealing ring 6 with through flow hole 13 axis normal directions; On the person in charge 1 two end interfaces, internal thread buckle 10 is set, lock water pipe at internal thread buckle 10 liner circular cone seal cartridges (11), arm 2 bores can be identical or inequality with being responsible for 1, and two end interfaces are established outside thread, are connected with riffled tube straight coupling (12).

Embodiment two: other are identical with embodiment one, mainly adopt tube-like interface on the interface of the person in charge 1 and arm 2, are responsible for and adopt anchor ear locking on 1, the circular snap lock of employing on the arm 2.

The utility model simplicity of design and ingenious can be simplified piping, and construction, use, change and repair are convenient, reduce manpower, save water resources, have free adjusting water output size, soil moisture is remained in the optimum plant growth scope, help improving the yield and quality of crop; Can science, rationally use water resources, the purpose of reach significant water saving, energy-conservation, saving of labor, increasing production, increase income is a water saving new technology good assistant of modern installations agricultural water-saving irrigation.
