Abstract
The invention relates to a gas flow blocking valve which comprises a pipe body, a baffle, a plurality of springs and a spring support.The spring support is fixed into the pipe body and provided with a liquid circulating hole.One end of each spring is fixed to the spring support, and the other end of each spring is fixed to the baffle.The inner wall of the pipe body is circumferentially provided with a groove.The thickness of the baffle is smaller than the width of the groove.The baffle is installed in the groove and tightly pressed to one side of the groove through extrusion of the springs.The baffle makes the springs contract under pressure of liquid, and the baffle moves to the other side of the groove to form a liquid channel.The gas flow blocking valve is simple in structure, the valve can selectively release liquid in a water pipe and block gas flow, and the valve is high in practicability and beneficial to application and popularization.
Description
Technical field
The present invention relates to a kind of valve, particularly relate to a kind of airflow-resistive valve.
Background technology
Existing water ga(u)ge or water meter all can rotate thus driving the change of reading under the effect of current or air-flow, that is, None-identified liquid stream or air-flow, therefore, when water pipe exists air-flow, can cause that the reading of water ga(u)ge or water meter is bigger than normal, beyond actual discharge. For water users, the rates ground of Running-water Company is the reading of water meter, if there is air-flow, then water users is accomplished by paying the water rate that the water yield more actually used than oneself is high, causes the air flow rate expense outside user amount paid.
Under room temperature state, the density of water is greater than atmospheric density, and in the long-pending horizontal pipe of same cross-sectional, pressure produced by the flowing material that density is big wants big, and water density is more than atmospheric density, and therefore, the pressure of water is greater than the pressure of air.
Summary of the invention
The technical problem to be solved is to provide a kind of airflow-resistive valve, and selectivity is by liquid stream and stops air-flow.
The technical solution adopted for the present invention to solve the technical problems is to provide a kind of airflow-resistive valve, including body, catch, some springs and spring support, described spring support is fixed on tubular body, spring support is with liquid stream through hole, described some spring one end and spring support are fixed, the other end and catch are fixed, described inboard wall of tube body, circumferentially have groove, the thickness of described catch is less than the width of groove, catch is installed on inside grooves, by the squeezing action of spring and groove one side compression, described catch makes spring contraction under flow stream pressure effect, catch moves formation flow channel to groove opposite side.
As one of the present invention preferred embodiment, sealed by sealing ring when described catch and groove one side compression.
As another preferred embodiment of the present invention, described some springs are uniformly distributed along the circumference of catch.
As another preferred embodiment of the present invention, described some springs are set to one, and a described spring one end is fixed with the center of spring support, the other end is connected with the center of catch.
As another preferred embodiment of the present invention, this airflow-resistive valve is arranged at inside pipe joint.
Beneficial effect
In the present invention, catch is installed in the groove of inboard wall of tube body, and is sealed with body by the squeezing action of spring. When tubular body is by liquid stream, the pressure that catch is produced by liquid stream is more than the active force of spring, and spring compresses, and forms path, thus ensureing passing through of liquid stream between catch and body; When tubular body exists air-flow, the pressure that catch is produced by air-flow is less than the active force of spring, and spring will not be compressed, and forming sealing closed circuit, passing through thus blocking air-flow between catch and body.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of the present invention.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is expanded on further. Should be understood that these embodiments are merely to illustrate the present invention rather than restriction the scope of the present invention. In addition, it is to be understood that after having read the content that the present invention lectures, the present invention can be made various changes or modifications by those skilled in the art, and these equivalent form of values fall within the application appended claims limited range equally.
A kind of airflow-resistive valve as shown in Figure 1, including body 1, catch 2, some springs 3 and spring support 4.
It is internal that spring support 4 is fixed on body 1, and spring support 4 is with liquid stream through hole, it is ensured that liquid stream normal through. Some spring 3 one end are fixed with spring support 4, and the other end is fixed with catch 2, and some springs 3 are uniformly distributed along the circumference of catch 2. As preferably, spring 3 is set to one, and the center of one end and spring support 4 is fixed, and the center of the other end and catch 2 is fixed.
Body 1 inwall, circumferentially having a groove 5, the thickness of catch 2 is less than the width of groove 5, and it is internal that catch 2 is installed on groove 5, and by the squeezing action of spring 3 and groove 5 one side compression, adopts sealing ring 6 to seal when catch 2 and groove 5 one side compression. Utilize pressure that unit are liquid stream the produces characteristic more than stream pressure, by selecting suitable spring 3, make the pressure that catch 2 is produced by spring 3 by the squeezing action power of catch 2 less than liquid stream, it is simultaneously greater than the pressure that catch 2 is produced by air-flow, so that translate to groove 5 opposite side at flow stream pressure effect lower stop piece 2, spring 3 compresses, flow channel is formed between catch 2 and body 1, liquid stream can be normal through, air-flow can not make spring 3 compress, for sealing structure between catch 2 and body 1, block air-flow and pass through.
This airflow-resistive valve is to be arranged at inside pipe joint and to be advisable, conveniently remove and install, and pipe joint can be metal, plastics or other materials. This airflow-resistive valve arrangement is simple, it is adaptable to the use that the fluid of all density variations dams, for instance main water metering, gasoline metering etc., practical, is conducive to popularization and application.
