Abstract
The utility model provides a novel pipe no-stop seal device which comprises an operation handle, four guide rods, a silk pole, a guide sleeve, a main shaft, a transmission shaft, a seal head, a pipe, a splint valve, a connecting box and a bypass. The utility model is characterized in that the utility model has four guide rods, wherein the outer wall of one guide rod is provided with a footage signal, the upper end of the main shaft is provided with a dial fork. The utility model has the advantages of stable and reliable operation, accurate and clear mark, and simple switch between the processes descending the seal head and folding the seal head.
Description
Technical field:
The utility model relates to a kind of maintenance unit of delivery line, particularly a kind of new pipeline online plugging device.
Technical background:
A kind of in the existing pipeline online plugging device, be the applicant with name be called " pipeline online plugging device ", application number is that 98211978.x is applied for, its composition by operating grip, guide rod, screw mandrel, guide sleeve, main shaft, transmission shaft, block head, pipe fitting, sandwich valve, connect case, bypass etc. and constitute.This technology in use has following some deficiency: 1, the guide rod of blocking device only is provided with two, and in operating process, because of moment of torsion is bigger, guide rod is easy to generate torsional deformation, and the shutoff operation can not be carried out smoothly; 2, do not establish the drilling depth indication device on the blocking device, understand the position that block head descends, need operator to go to measure with the tape measure of carrying, this not only carries the tape measure trouble, and artificial tape measure is also not too accurate; 3, blocking device is in the conversion of decline block head and gathering block head two operation process, need operator to come striking gear to achieve the conversion of operation with an interim instrument, effort and loaded down with trivial details is obvious in operation, this mode of operation is very original, does not meet the requirement of modern industry.
Summary of the invention:
The purpose of this utility model is that at the existing deficiency of above-mentioned blocking device, and it is reliable, convenient simple and direct to propose a kind of stable operation, shows clear accurate new pipeline online plugging device.
Can realize the purpose of this utility model by following technical proposals, a kind of new pipeline online plugging device, comprise operating grip, guide rod, screw mandrel, guide sleeve, main shaft, transmission shaft, block head, pipe fitting, sandwich valve, connect case, bypass, it is characterized in that, guide rod is formed by four, wherein the outer wall of a guide rod is provided with the drilling depth sign, is provided with a shift fork in the upper end portion of main shaft.
Shift fork is made of shift fork dish and shifting fork piece, and screw mandrel is enclosed within the shift fork.
Four its cross sections of guide rod are arranged as a square.
Effect of the present utility model is: 1, stable operation is reliable, this is, has established four guide rods on blocking device, and four guide rods are an arranged in squares on its cross section, form a stable mechanical relationship, or else can occur the situation of guide rod torsional deformation in operation; 2, sign is accurately clear, can accurately grasp the drilling depth situation, and this is, have at least one to be provided with drilling depth and to indicate (also claiming to indicate bar) on the blocking device in set four guide rods, where block head drops to, and accurate response comes out on the sign bar, no longer needs go to measure with tape measure; 3, the conversion of decline block head and gathering block head two operation process is convenient simple and direct, and this by mobile plectrum, can conveniently realize decline block head and the conversion of drawing block head two operation process in because be provided with a shift fork on the main shaft of blocking device.
Below in conjunction with embodiment and accompanying drawing the utility model is further set forth:
Description of drawings:
Accompanying drawing 1 is a schematic representation of the present utility model;
