Abstract
The utility model discloses a hydraulic forcible pipeline stop valve, which mainly comprises leads (1), a spool (2), hydraulic oil (3), a valve body (4), a lead-sealing box (5), a hydraulic oil pump (6), an oil tank (7) and set screws (8), the oil tank (7) is fixed on the hydraulic valve body (4), the lead-sealing box (5) and the leads (1) are arranged on the top of the oil tank (7), and the hydraulic oil pump (6) is fixed on the top of the valve body (4). After being forced to be closed, the spool presses a metal pipeline until the metal pipeline is forcedly squeezed to deform to be closed. When the spool is opened again, the pipeline cannot be restored, and needs to be replaced. The lower half part of the valve body (4) and the head of the spool (2) can be respectively replaced, so that the hydraulic forcible pipeline stop valve can be adapted to metal pipelines with various diameters. After the structure is adopted, the hydraulic forcible pipeline stop valve prevents potential safety hazards which can be caused when conventional pipeline valves cannot be closed due to damage, has the characteristics of simple structure, long service life and the like, and is safe and reliable to use.
Description
Technical field
The utility model relates to a kind of stop valve, particularly a kind of novel cutoff valve that can force the various metallic conduits of stopping.
Background technique
At present, known stop valve is by valve body, valve gap, spool, valve seat, operating device and sealing fastener group and form.In the use, the valve member of valve more or less always occurs leaking and can't closing problem, especially at chemical field anti-riot, fire prevention, anti-poisoning control are caused difficulty, accident frequently takes place, for this reason, many manufacturers can force stop valve by the movable hydraulic pipeline that uses at the problems referred to above exploitation is a kind of, but do not find comparatively reasonably solution so far as yet.
The model utility content
In order to overcome the above-mentioned disadvantage that existing valve exists, the purpose of this utility model provides a kind of simple and reasonable, and effectively stopping leaks the hydraulic pipeline pressure stop valve of metallic conduit.
The technical solution adopted for the present invention to solve the technical problems, it mainly contains lead-in wire, spool, hydraulic oil, valve body, lead-in wire sealing case, hydraulic-pressure pump, fuel tank, retaining screw formation, fuel tank is fixed on the hydraulic valve, the fuel tank top is furnished with sealing wire box and lead-in wire, oil hydraulic pump, fuel tank is fixed on the valve body top, and pipeline must be changed pipeline again with irreversible when opening spool again after the spool positive closing.After adopting said structure, solve existing pipeline valve and damaged the safety of bringing in the time of to close and draw trouble, had characteristics simple in structure, safe and reliable.

Embodiment
Fig. 1, Fig. 2, Fig. 3, Figure 4 shows that specific embodiments of the present invention, it mainly contains lead-in wire (1), spool (2), hydraulic oil (3), valve body (4), lead-in wire sealing case (5), hydraulic-pressure pump (6), fuel tank (7), retaining screw (8) formation, fuel tank (7) is fixed on the hydraulic valve (4), the fuel tank top is furnished with sealing wire box and lead-in wire, oil hydraulic pump (6) is fixed on the valve body top, when spool positive closing back valve core roof pressure metallic conduit makes to forcing extrusion-deformation to be closed.Pipeline must be changed pipeline again with irreversible when opening spool again.The Lower Half of valve body (4) and the head of spool can change to adapt to the use of various different-diameter metallic conduits respectively.After adopting said structure, solved existing pipeline valve and damaged the safety of bringing in the time of can not closing and draw trouble, have simple in structure, safe and reliable, characteristics such as the life-span is long.
