Generally speaking, most of the crushing valve conveying pipelines use connecting devices such as welding or flanges to connect long-distance pipelines, and use valves for opening and closing control or flow regulation. The disadvantages of poor versatility and inability to connect fixed pipelines are very inconvenient. Let's learn about the production method of pipeline crushing valves for hydraulic elevators!

Technical implementation elements:

The purpose of this utility model is to provide a pipeline rupture valve for a rail-type hydraulic lift in order to solve the problems raised in the above-mentioned background technology.

In order to achieve the above-mentioned purpose, the utility model has a valve core with a first connecting pipe and a second connecting pipe on the left and right ends respectively, and the first connecting pipe and the second connecting pipe are of the same structure and size, And two arc grooves are symmetrically opened on the upper and lower sides inside the first connecting pipe and the second connecting pipe, and the other end of the arc plate is fixedly connected through the arc groove and extends to the arc groove at equal intervals. The three adjustment screws on the upper and lower outer sides of the first connecting pipe and the second connecting pipe are provided with compression springs on the stopper located on the outer side of the adjustment screw and below the stopper. The other end of the pipe is provided with an annular groove on the inner side of the above-mentioned installation plate, the inside of the above-mentioned annular groove is evenly and equally spaced with 6 first circular holes, and the other end of the above-mentioned second connecting pipe is fixedly connected to the installation plate. On the disk 2 , a ring-shaped convex plate is fixedly arranged at a position corresponding to the ring-shaped groove on the above-mentioned mounting disk 2 .

Preferably, an anti-corrosion coating is fixed on the inner surface of the circular arc plate.

The anti-corrosion coating is fixed on the inner surface of the arch plate where the crushing valve is installed, which can effectively prevent corrosion and play a protective role.

Preferably, in the inside of the first connecting pipe and the second connecting pipe, three threaded holes are fixedly arranged at positions corresponding to the arc grooves, and an internal thread suitable for the adjusting screw is opened inside the threaded holes.

The crushing valve is arranged inside the first connecting pipe and the second connecting pipe, three threaded holes are fixedly arranged at the positions corresponding to the arc grooves, and internal threads suitable for adjustment screws are set up in the inside of the threaded holes, so that the adjustment of the adjustment screws is fixed. made easy.

Preferably, one end of the compression spring is fixed on the outer surface of the first connecting pipe and the second connecting pipe, and the other end of the compression spring is fixed on the bottom of the stop rod.

The above describes the manufacturing method of the pipeline breaking valve for hydraulic elevator, and does not limit the present invention. The present invention is described in detail with reference to the above-mentioned embodiments. technical means, or equivalently replace part of its technical features
