Abstract
A kind of breather valve with emergency cut-off structure is the utility model is related to, valve love housing upper surface is communicated with breather valve, and valve is loved enclosure interior and loved provided with valve, and valve love lower section is provided with gravitation ball, and gravitation ball is connected by connecting rod and valve love.Control valve is balanced or waved by gravitation ball and loves open and-shut mode, and when tank body run-off the straight or gravitation ball stress causes valve love to close when there is accident, avoids industrial chemicals leakage from bringing potential safety hazard and environmental pollution.
Description
Technical field
A kind of breather valve is the utility model is related to, particularly a kind of breather valve with emergency cut-off structure, belongs to chemical industry
Plant equipment accessory fabricates field.
Background technology
Chemical tank easily leaks in run-off the straight and security incident from the valve port of breather valve, causes safety hidden
Suffer from.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of breather valve with emergency cut-off, is put down by gravitation ball
Control valve love open and-shut mode is weighed or waves, when tank car tilts or accident occurs, gravitation ball is sagging so that valve love closing, avoiding
Chemical product leaks.
To solve problem above, concrete technical scheme of the present utility model is as follows：A kind of exhaling with emergency cut-off structure
Valve is inhaled, valve love housing upper surface is communicated with breather valve, and valve is loved enclosure interior and loved provided with valve, and valve love lower section is provided with gravitation ball, gravity
Ball is connected by connecting rod and valve love.
Junction is fallen in love with valve below described breather valve holds position of opening corresponding.
Loved with junction below breather valve in same level, the lower surface of valve love less than valve the upper surface of described valve love
The lower surface of housing.
What the utility model was brought has the beneficial effect that：Open and-shut mode is loved by gravitation ball balance control valve, works as Tank tilting
Or occur gravitation ball during accident it is sagging so that valve love close, avoid chemical products from leaking.
Brief description of the drawings
Fig. 1 is the structural representation of the breather valve with emergency cut-off structure.
Wherein, 1- valves love housing, 2- breather valves, the love of 3- valves, 4- gravitation balls, 5- connecting rods.
Embodiment
As shown in figure 1, a kind of breather valve with emergency cut-off structure, valve love housing 1 upper surface is communicated with breather valve 2,
The inside of valve love housing 1 is provided with valve love 3, and the lower section of valve love 3 is provided with gravitation ball 4, and gravitation ball is connected by connecting rod 5 with valve love 3.
The described lower section junction of breather valve 2 is corresponding with valve 3 upper end position of opening of love.
The upper surface of described valve love 3 is less than with the lower section junction of breather valve 2 in same level, the lower surface of valve love 3
Valve loves the lower surface of housing 1.
For chemical tank car in smooth-ride or parking, gravitation ball 4 is in the state perpendicular to ground, valve love 3 and breather valve 2
UNICOM's state is remain, occurs Tank tilting or security incident during traveling, gravitation ball 4 occurs back and forth or left and right and waved,
Waving for gravitation ball 4 drives the movement of valve love 3 so that perforate and the junction position of breather valve 2 of valve love 3 interlock, i.e., valve love 3 and
Breather valve 2 disconnects, and prevents chemical substance from being leaked from breather valve.
Above-described is only preferred embodiment of the present utility model.It should be pointed out that the ordinary skill people for this area
For member, on the premise of the utility model principle is not departed from, some variations and modifications can also be made, also should be regarded as belonging to this
The protection domain of utility model.
