Abstract
The invention discloses a hydraulic forcible pipeline stop valve. The hydraulic forcible pipeline stop valve mainly comprises leads (1), a valve core (2), hydraulic oil (3), a valve body (4), a lead sealing box (5), a hydraulic oil pump (6), an oil tank (7) and fixing screws (8); the oil tank (7) is fixed to the hydraulic valve body (4); the lead sealing box and the leads are arranged on the top of the oil tank; the hydraulic oil pump (6) is fixed at the top end of the valve body. After the valve core is closed forcibly, the valve core presses a metal pipeline until the metal pipeline is forcedly extruded to deform and close. When the valve core is opened again, the pipeline cannot be restored and is required to be replaced. The lower half part of the valve body (4) and the head part of the valve core can be respectively replaced, so that the hydraulic forcible pipeline stop valve can be adapted to metal pipelines with different diameters. After the adoption of the structure, potential safety hazards caused when the existing pipeline valves cannot be closed due to damage are avoided; the hydraulic forcible pipeline stop valve has the characteristics of simple structure, safety and reliability in use, long service life and the like.
Description
Technical field
The present invention 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 use, the valve member of valve more or less always there will be and leaks and cannot closing problem, especially at chemical field, anti-riot, fire prevention, anti-poisoning control are caused to difficulty, accident frequently occurs, for this reason, many manufacturers for the problems referred to above exploitations is a kind of can the movable hydraulic pipeline mandatory stop valve using, but not yet find so far comparatively reasonably solution.
Summary of the invention
The above-mentioned disadvantage existing in order to overcome existing valve, the object of this invention is to provide one simple and reasonable, and effectively stopping leaks the hydraulic pipeline mandatory 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 hydraulic valve, top of oil-tank is furnished with sealing wire box and lead-in wire, oil hydraulic pump, fuel tank, is fixed on valve body top, and in the time again opening spool after spool positive closing, pipeline must be changed pipeline again by irreversible.Adopt after said structure, solved the safety of bringing when existing pipeline valve damage can not be closed and drawn trouble, there is feature simple in structure, safe and reliable.
Brief description of the drawings
Fig. 1 be the cross-section structure of the present invention when closed look intention,
Fig. 2 be the cross-section structure of the present invention while opening look intention,
Fig. 3 be side sectional view of the present invention,
Fig. 4 be side of the present invention sectional structure look intention,
Embodiment
Fig. 1, Fig. 2, Fig. 3, Figure 4 shows that specific embodiment of the invention scheme, 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 hydraulic valve (4), top of oil-tank is furnished with sealing wire box and lead-in wire, oil hydraulic pump (6) is fixed on valve body top, presses metallic conduit make to forcing extrusion-deformation to be closed when spool positive closing back valve core top.While again opening spool, pipeline must be changed pipeline again by irreversible.The Lower Half of valve body (4) and the head of spool can change to adapt to respectively the use of various different-diameter metallic conduits.Adopt after said structure, solved the safety of bringing when existing pipeline valve damage can not be closed and drawn trouble, there is the features such as simple in structure, safe and reliable, life-span length.
