CN201078543Y - Improved simple Tunion of branch pipe with block valve - Google Patents

Abstract

The utility model discloses a modified simple type tee coupling with a branch pipe attached with a block valve, which belongs to the fittings of pipelines for civil construction or agricultural irrigation. The utility model is composed of a main pipe and a branch pipe and the two are jointed with each other in coincidence; block valve bodies are directly arranged on the branch pipe; the branch pipe caliber of the tee coupling is able to be identical with or different from the main pipe. The utility model is characterized in that: valve rods of the block valves are connected with the block valve bodies through bolts. The utility model has the advantages of convenient disassembly and maintenance, safe and reliable operation and broad market prospect.

Description

Prop up the simple and easy tee union of modified model 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

In the water saving new technology, special branch technique in the industrialized agriculture water-saving irrigation, the tee union of the pipe racks block valve of my invention adopts block valve is set on arm, but being connected between valve gap and the valve body adopts seizing type to connect or be threaded, patent as my application, the patent No. is: 200520015355.4, like this, under certain position and certain pressure, or with the valve rod rotation, valve gap can be dashed by the hydraulic pressure in the pipe and fly.

Summary of the invention

The purpose of this utility model provides a kind of low cost, prevents that valve gap is managed under the inner high voltage power towards flying the simple and easy tee union of modified model of a pipe racks block valve.

The simple and easy tee union of modified model 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 valve rod of cut-off valve adopts wedge-shaped structure, directly is connected with screw with valve base.

The utility model directly is provided with cut-off valve on arm, the valve rod of cut-off valve adopts wedge-shaped structure, directly is connected with nut with valve base, and it is more firm to have a connection, and sealability is better, and change and repair are convenient, operates reliably, safety, and cost is lower.

Description of drawings

Accompanying drawing 1 is the simple and easy tee union structural representation of modified model of a pipe racks block valve;

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 body; 6---handgrip; 7---buckle; 8---screw.

Embodiment

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

The simple and easy tee union of modified model of a pipe racks block valve as shown in Figure 1 is made up of the person in charge 1 and arm 2, buckle 7, the person in charge 1 connects with arm 2 kisses, with being responsible for 2 engagements cut-off valve 3 is set directly at arm 1, arm 2 bores of tee union can be identical or inequality with being responsible for 1; The valve rod 4 of cut-off valve 3 adopts the handgrip 6 of " 7 " font, valve rod 4 is an integral structure with handgrip 6, valve rod 4 is a wedge-shaped structure, like this, sealability is better between valve rod 4 and the valve body 5, and valve rod 4 bottoms adopt direct screw 8 to be connected with valve body 5 bottoms, easy accessibility, easy to maintenance, operation is reliable, safety, and cost is lower.Be a water saving new technology good assistant of modern installations agricultural water-saving irrigation.
