Abstract
The utility model relates to a draw-off pipe-cleaning device. A pressure spring type discharge valve is installed on the draw-off pipe-cleaning device. A hollow drilling central rod [4] is composed of a valve seat [1], a valve barrel [5], and a protective cover [7]; a spring [6] which is sheathed with the tail part of the central rod [4] is provided with a barrier spring [3]; the front end of the spring [3] props a valve [2] to make the valve [2] blocked on the draw-off hole of the valve seat [1]. When the draw-off pipe-cleaning device is blocked, the draw-off valve can be opened automatically to make the fluid stream and the gas stream in the pipe expedite continuously, so that the caused accident of the pipe-cleaning device can be avoided so as to prevent stopping production. The utility model has the safe and protective effect on the operation of cleaning pipe; the utility model can make the probability of the accident and the stop production greatly reduced; the labor strength of the constructors can be broken down.
Description
The utility model is the equipment that pipeline takes out stains, and relates to the field of preventing and kill off of pipe-line system and general dirt.
Pipe-line system is often used the pigging pipeline at present, and mechanical tube cleaner wherein is when work, and the regular meeting that is hampered takes place to stop up and cutout, is called the pigging fault on the engineering.Its consequence is that pipeline builds the pressure, and easily causes pipeline breaking.Handling the pigging fault must stop production, and brings greater loss to production.
The purpose of this utility model is a kind of drainage type wiper of design, and when wiper was hampered obstruction, in time earial drainage was avoided building the pressure, stopping.
The technical scheme that addresses this problem is exactly that an eduction valve is installed on mechanical tube cleaner.The structure of this eduction valve can be in a variety of forms, but the simplest be compressed spring type, as shown in Figure 1.Promptly the cavity center that constitutes at valve seat [1], valve cylinder [5] and protecting cover [7] is worn center-pole [4], its front end passes the centre bore of valve seat [1], the rear end puts spring abutment [6], spring [3] afterbody is contained on the spring abutment [6], front end heads on valve [2] and gets lodged on the discharge orifice of valve seat [1], valve cylinder [5] leaves a plurality of holes on every side, and the protecting cover of afterbody [7] is twisted solid on valve cylinder [5], and spring abutment [6] links with spiral shell with valve cylinder [5] afterbody and connects.
Valve seat [1] end face becomes wheel wheel shape, and the front end face of valve [2] is flattened on the double-ring contact-making surface of valve seat [1] from valve seat [1] inboard.Whole eduction valve is owing to working in the defeated medium of pipe, so should adopt corrosion resistant material or anti-corrosion top layer.Certainly, the medium difference is also different to anti-corrosion requirement.
The principle of this eduction valve is to utilize the elastic force of spring that the discharge orifice on the valve seat [1] is blocked when operate as normal, and the wiper front and back are isolated, and forms certain pressure reduction, and wiper can advance with medium.When wiper is hampered obstruction, build the pressure when to a certain degree also the top is not walked, under the situation that is no more than the pipeline maximum allowble pressure, make eduction valve open earial drainage, the protection pipeline is not damaged.The key here is the design of pressure that eduction valve is opened, and in fact the pepeline characteristic of each bar pipeline has nothing in common with each other, so this force value can be not identical yet.When reality is used, as long as change the spring [3] of different elastic force, can satisfy the needs of different pipeline piggings fully, in other words or the seriation eduction valve of configuration different pressures setting value, the seriation spring of configuration different pressures setting value forms tandem product.
The combination of this eduction valve and existing machinery wiper easily resembles shown in Figure 2ly, as long as eduction valve is installed in the center of pipe cleaner rubber cup, connected mode is a convenience with the spiral shell button.Certainly can directly be welded on the leather cup dish.
Eduction valve mainly plays the safeguard protection effect to pigging operation, on the wiper it is housed, and the probability of fault and stopping production greatly reduces, and workmen's labour intensity also alleviates for it, and can be more relieved bold have thrown in operation.
The utility model is simple, reliable, install additional on wiper conveniently, is one perfect preferably to mechanical tube cleaner, can overcome the deficiency of existing wiper.
