Abstract
The invention discloses a mechanical water-break self-closing valve which comprises a valve body (2) with a hollow cavity body, a water inlet (1), a water outlet (6) and a valve cover (8). The water inlet (1) and the water outlet (6) are formed in the valve body (2), the valve cover (8) is combined with the valve body (2), the water inlet (1) is arranged to be lower than the water outlet (6), and the mechanical water-break self-closing valve further comprises a draw rod (13) which is arranged in the cavity body of the valve body. A spring (7) is sleeved on the draw rod, the lower end of the draw rod is connected with a valve plug (5), the outer diameter of the valve plug (5) is equal to the inner diameter of the cavity body of the valve body, the position of the valve plug on the draw rod is limited through a fastening part, and a notch is arranged on the draw rod. The notch can be clamped with a movable spring bolt (9) of a lock (11) arranged on the valve cover. In the process of water breaking, the spring rebounds, the draw rod shifts downwards, the valve plug is pushed to the bottom end to seal the water outlet, the movable spring bolt is clamped in the notch, a whole mechanism is locked, a water running phenomenon is prevented, and water use safety is ensured.
Description
Technical field
The present invention relates to the water valve technical field.
Background technique
Forget to close or do not tighten to cause the more than phenomenon of current often to occur because of water tap in life, bring certain economic loss and potential safety hazard.As follows in the research of self-closing valve for water cut direction both at home and abroad at present: as to be mainly to be controlled to be the master with circuit at home; Abroad take pure mechanism structure as main, and mechanism is loaded down with trivial details, and achievement in research rests on the model machine of laboratory mostly, and distance practical, industrialization on a large scale also has a certain distance.
Summary of the invention
The invention technical problem to be solved is to provide a kind of simple in structure, highly sensitive mechanical type self-closing valve for water cut.
The invention is for solving the problems of the technologies described above, by the following technical solutions:
A kind of mechanical type self-closing valve for water cut, the valve gap that comprises hollow cavity valve body, is opened in water intake on valve body and water outlet, is combined with valve body, water intake is lower than the water outlet setting; Also comprise the pull bar that is arranged in the valve body cavity, sheathed spring on described pull bar, pull bar lower end connecting external diameter is equal to the valve plug of valve body cavity internal diameter, limits valve plug position on pull bar by fastening piece; Also be provided with breach on described pull bar, breach can with the movable dead bolt of the lockset that arranges on valve gap buckle mutually.
Further, described valve body and valve gap screw by thread seal.
Further, during normal water flowing, hydraulic pressure pushes up valve plug above water outlet, the gravity sum balance of the elastic force of hydraulic pressure and spring and pull bar.
Further, when cutting off the water supply, recoil of spring, pull bar are to bottom offset, and valve plug is positioned at below water outlet, and movable dead bolt is buckled in breach.
Further, also be provided with the key that control activity dead bolt stretches out and retracts on described lockset.
In the normal water supply situation, this valve just is equivalent to a common water tap, and when cutting off the water when cutting off the water supply suddenly, valve plug is automatic and quick closes water outlet, when again again during water, the water leaking phenomenon can not occur, and barrier has been demonstrate,proved water safety.
The mechanical type self-closing valve for water cut of the invention realize to be controlled based on mechanical structure fully, and utilizes mechanically common structure spring and pull bar to realize, and is simple in structure; And this valve has been removed the circuit control section, has saved the unstability of electric power resource and automatical control system.In addition, the buckle structure of the breach of movable dead bolt and pull bar, mechanical sensitivity is high.
Description of drawings
Fig. 1 is the mechanical type self-closing valve for water cut surface structure schematic diagram of the invention preferred embodiment;
Fig. 2 is the structural representation of the mechanical type self-closing valve for water cut of the invention preferred embodiment;
Embodiment
In conjunction with Fig. 1 and Fig. 2, the mechanical type self-closing valve for water cut of the present embodiment comprises hollow cavity valve body 2, the valve body upper end open; Be opened in water intake 1 and water outlet 6 on valve body, water intake 1 arranges lower than water outlet 6.Valve body 2 upper ends and valve gap 8 screw by thread seal, are provided with lockset 11 on valve gap.Pull bar 13 is set in the valve body cavity, sheathed spring 7 on pull bar, the pull bar lower end is multidiameter shaft, on little journal axle, connecting external diameter is equal to the valve plug 5 of valve body cavity internal diameter, limits valve plugs positions on pull bar by pad 4, nut 3.Also be provided with breach on pull bar, breach can with the movable dead bolt 9 of the lockset 11 that arranges on valve gap buckle mutually.
During normal water flowing, hydraulic pressure with valve plug 5 tops to water outlet 6 tops, the gravity sum balance of the elastic force of hydraulic pressure and spring 7 and pull bar 13.When cutting off the water supply, hydraulic pressure is vanishing at short notice, at this moment, spring 7 resiliences, pull bar 13 is to bottom offset, and valve plug 5 is pulled to the bottom, has sealed water outlet, and movable dead bolt 9 is buckled in breach, and integrated model is lockable.When water again, because pull bar is lockable, hydraulic pressure can not be with valve plug jack-up, the phenomenon of can not metalling run out.When the needs water, the key 12 of twisting on lockset 11, lock body is opened, and movable dead bolt 9 is regained, the water jack-up valve plug that makes progress, water pressure and pull bar, spring reach balance again, and water outlet is opened, and the water route is unimpeded, normal water supply.
