Abstract
The utility model belongs to the technical fields of valves, particularly relates to a stop device for gas or liquid and mainly solves the problems that in the current valve, the reaction speed is low and the reaction time is long when gas or liquid is stopped from flowing, so that the aim of quickly stopping a conveying system in time cannot be achieved. The utility model has the technical scheme that the stop device for gas or liquid comprises a main cavity, a secondary cavity communicated with the main cavity, a tamper, a push-and-pull rod and an elastic baffle, wherein the temper is arranged in the secondary cavity; the push-and-pull rod is arranged at one side of the edge of inner wall of the secondary cavity and extends to the outside of the secondary cavity; the elastic baffle is arranged at one side of the inner wall of the secondary cavity; two ports of the main cavity are opened; the diameter of the upper port is smaller than that of the lower port; a right port of the secondary cavity is closed; and the diameter of the temper is great than that of the upper port. The stop device has the advantages of simple operation, high reaction speed, high work efficiency, strong controllability, and the like.
Description
Technical field
The utility model belongs to valve technology field, is specifically related to a kind of gas, liquid by device.
Background technique
Valve is the controlling component in the fluid delivery system, have by, adjusting, water conservancy diversion, prevent functions such as adverse current, voltage stabilizing, shunting or overflow pressure release, shortcomings such as but existing valve exists working stroke long when the blocking-up gas-liquid, and operation is slow, and closed needed time is long, valve can satisfy the demand of blocking-up in the ordinary course of things, but under the state of emergency, as gasoline, when methane gas etc. catch fire, need rapidly transporting system to be blocked, this moment, valve just can not be satisfied the demand.
Summary of the invention
The purpose of this utility model is to have when the blocking-up gas-liquid flows at present valve that reaction velocity is slow, the reaction time is long, can not satisfy the problem of in time blocking transporting system fast, and provide a kind of reaction velocity gas, liquid fast, that can block transporting system quickly to end device.
The utility model is to address the above problem the technological scheme of taking to be:
A kind of gas, liquid are by device, the secondary cavity that comprises main cavity, communicates with main cavity, wherein: it also includes obstruction, pull bar, elastic baffle, described obstruction is located in the secondary cavity, pull bar is located at secondary cavity inner wall edge one side and extends to the outside of secondary cavity, and described elastic baffle is arranged on secondary cavity inner wall one side; The two-port of described main cavity is an open type, and the diameter of upper end-hole is less than the diameter of lower end mouth; The right output port of described secondary cavity is closed; The diameter of described obstruction is greater than the diameter of upper end-hole.
Wherein said obstruction is a kind of in spheroid, hemisphere, cone or the cylindrical body.
The utility model adopts technique scheme, utilize external force to promote pull bar, make pull bar promotion obstruction cross elastic baffle and enter main cavity, utilize the pressure of the fluid of the continuous circulation of lower end mouth that obstruction is shut upper end-hole, in time block the mobile of main cavity inner fluid fast thereby reach.Advantage such as therefore, compared with prior art, the utlity model has that simple to operate, reaction velocity is fast, high working efficiency and controllability are strong.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
