Abstract
The utility model relates to a throttling-type overflow device, which comprises a throttling orifice plate, wherein the throttling orifice plate is arranged in a pipeline or on a valve body inlet; the center shaft position of the throttling orifice plate is provided with a round hole smaller than the internal diameter of a pipeline or a valve body outlet; and the outer peripheral side of the throttling orifice plate is in tight fit with the inner wall of the pipeline or the inner wall of the valve body inlet. According to the throttling-type overflow device disclosed by the utility model, the overflow self-closing function is realized by the throttling orifice, and the throttling-type overflow device has the advantages of simple structure, easiness in installation and stable and reliable mechanism work performance and does not need to be regulated.
Description
Technical field
The utility model belongs to the pipeline valve equipment technical field, relates to the fluid line overflow means, particularly a kind of throttle type overflow means such as gas, liquid.
Background technique
Raising along with economic development and living standards of the people, city and industrial fuel gas are increasingly extensive, combustion gas becomes indispensable dependence in people's life, but people understand not comprehensive to the safe handling combustion gas, even the use of combustion gas is not had the consciousness of safety precaution, thereby unnecessary loss and accident have been caused.Natural gas companies is generally heightened supply gas pressure for guaranteeing air feed at present, and the characteristics of gas self-closing valve are autoshutdowns when pressure surpasses setting pressure.The gas voltage adjusting device is different because of environment, pipeline gas high voltage supply phenomenon easily occurs, in the repairing process, then must at first cut off source of the gas, if the user does not have timely or forgets valve before the valve of closing burner, the kitchen range, when air feed again, will cause because of artificial fuel gas divulges, and personnel and social safety around the entail dangers to.The gas self-closing valve that uses at present is varied, has directly to cross drift angle and close, and also has induction pressure to close etc.Be the safety problem that can solve a part of gas pipeline technically, but not comprehensive and more single, work in the range of pressure values of setting in the time of can only dispatching from the factory in producer, exceed or be difficult to reach the purpose that realizes autoshutdown when being lower than setting value; Like this in real life, when in a single day the higher flexible pipe end of pipeline gas self closing stop valve outlet end comes off or breaks, and be higher than the working pressure scope and not during ultrahigh pressure when pipeline pressure, present gas self-closing valve is in not closed condition, the personnel that very easily cause injure and property loss, and the sense of insecurity of society.
The model utility content
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, a kind of throttle type overflow means is provided, this device realizes that less than the throttle orifice of gas or liquid outlet diameter overcurrent is self-closing by internal diameter, it is simple in structure, be easy to install, and do not need to regulate mechanism's stable and reliable working performance.
The purpose of this utility model solves by the following technical programs:
This throttle type overflow means comprises being arranged in the pipeline or the restricting orifice of valve body inlet that the central shaft position of described restricting orifice offers the circular hole less than pipeline or valve outlet internal diameter.
Further, the outer circumferential side of above-mentioned restricting orifice and inner-walls of duct or valve body inlet inwall closely cooperate.
The utlity model has following beneficial effect:
Throttle type overflow means of the present utility model is simple in structure, is easy to install, and need not to regulate mechanism's stable and reliable working performance.
Description of drawings
Fig. 1 is overall structure schematic diagram of the present utility model (being installed in pipeline or the valve body);
Fig. 2 is that the utility model is installed in the structural representation in the valve body.
Wherein, 1 is restricting orifice; 2 is circular hole.
Embodiment
Referring to Fig. 1 and Fig. 2, throttle type overflow means of the present utility model comprises and is arranged in the pipeline or the restricting orifice 1 of valve body inlet, and the central shaft position of this restricting orifice 1 offers the circular hole 2 less than pipeline or valve outlet internal diameter.The outer circumferential side of described restricting orifice 1 and inner-walls of duct or valve body inlet inwall closely cooperate.
What need statement is, the utility model throttle type overflow means required for protection can not only be installed in as shown in Figure 2 the valve body, and it also can be installed in any pipeline for delivery of fluid forms such as gas or liquid, can realize its function equally.
Claims (2)
1. a throttle type overflow means is characterized in that, comprises being arranged in the pipeline or the restricting orifice (1) of valve body inlet, and the central shaft position of described restricting orifice (1) offers the circular hole (2) less than pipeline or valve outlet internal diameter.
2. throttle type overflow means according to claim 1 is characterized in that, the outer circumferential side of described restricting orifice (1) and inner-walls of duct or valve body inlet inwall closely cooperate.
