Abstract
The utility model discloses a pressure control one-way valve. The pressure control one-way valve is composed of an external pipe, an internal round ball and a spring, wherein the left end and the right end of the external pipe are respectively provided with a port, the ports are connected with other pipes, and the round ball and the spring are placed inside the external pipe. When the pressure of air or liquid is larger than the elasticity of the spring, the round ball is pushed to move inward and compress the spring, and the pressure control one-way valve is opened. When the pressure of the air or the liquid is smaller than the elasticity of the spring, the round ball is pushed to one port of the external pipe to abut against the port of the pipe, the air or the liquid is stopped from flowing, and the pressure control one-way valve is in a closed state. Meanwhile, the elasticity of the spring can be adjusted to achieve the function that the air or the liquid under specific pressure can pass through the pressure control one-way valve.
Description
Technical field
The utility model relates to the one-way cock field, is a kind of elastic force by Regulation spring specifically, the pressure control one-way valve of required pressure size when reaching control gas or liquid by one-way cock.
Background technique
In present technology, most one-way cock can only be controlled the one-way flow of gas or liquid, and keying speed is slower, and gas-tight property is not strong, causes easily leakage.Be exactly the part rapid wear in addition, cause the working life of valve shorter, the waste resource.All there is above said problem in such as patent CN95209095.3, CN2309466Y etc.
The model utility content
The purpose of this utility model is to design a kind of pressure control one-way valve, realizes that the gas of control specified pressure size or liquid could unidirectional functions by valve.
In order to realize above-mentioned functions, the utility model will be by the following technical solutions:
The pressure control one-way valve, described pressure control one-way valve is made of external pipe, inner circular ball and spring, and two ends, the pipeline left and right sides, outside respectively are provided with the port that connects other pipeline, and ball, spring are placed in the inside of external pipe.
By the elasticity of spring self, shift ball onto take over the road port, make ball withstand pipe end, flowing of blocking-up gas or liquid makes the pressure control one-way valve be in closed condition.
When gas or fluid pressure during greater than the elastic force of spring, promote inwards mobile and Compress Spring of ball, cracking pressure control one-way cock is realized the one-way flow of gas or liquid.
When realizing the one direction ventilation, also can be by the elastic force of Regulation spring, required pressure when reaching control gas or liquid by one-way cock.
Adopt above technological scheme, usefulness of the present utility model is:
Respectively there is a port that connects other pipelines at the two ends, the left and right sides of pressure control one-way valve external pipe, and middle pipe section is a wide middle, and the pipeline that two ends are narrower, the diameter of ball are between wide pipeline and narrow pipeline.A spring is placed in the bottom of ball, and it promotes the power that ball is closed pipeline as providing.By the combination of external pipe, inner circular ball and spring, cooperate the elastic force of Regulation spring, required pressure when reaching automatic control gas or liquid by one-way cock.
Pressure control one-way valve of the present utility model only utilizes the combination of external pipe and inner ball and spring, realizes the gas of control different pressures or the function of liquid one way flow.And with the flow that can control according to the size of internal diameter of the pipeline gas or liquid.So both can reduce redundancy, save cost, can also simplify structure, the reduction manual operation.
Description of drawings
The structural representation of Fig. 1 pressure control one-way valve
Embodiment
The below is described further the utility model by reference to the accompanying drawings.
Description of reference numerals:
1---connecting port, the left side
2---connecting port, the right
3---external pipe
4---inner ball
5---contained spring
6---arrow represents the flow direction of one-way cock control gas or liquid
Referring to accompanying drawing 1.Elasticity by spring 5 self, shift ball 4 onto narrow pipe end place, make the pressure control one-way valve be in closed condition, the pressure that produces when the pressure of gas or liquid is during less than the elastic force of spring 5 self, ball 4 can't mobile Compress Spring 5, still withstand on the external pipe left port, shown in solid line among Fig. 1, thereby blocking-up gas or liquid is mobile.
When the pressure of gas or liquid during greater than the elastic force of spring 5, promote inwards mobile and Compress Spring 5 of ball 4, so that pressure valve is opened, realize the one-way flow of gas or liquid, shown in the dotted line among Fig. 1.
The user can determine required gas or the pressure of liquid according to the actual conditions of self, selects suitable spring, thereby realizes the gas of specified pressure size or the purpose that liquid just can be opened the pressure control one-way valve.
By the combination of external pipe, inner circular ball and spring, when realizing the one direction ventilation, can be according to the opening and closing of needed automatic pressure control valve door.
The utility model not only is confined to the structure shown in the figure, and its inner control gear can also change other shape into.Above 26S Proteasome Structure and Function all is considered as extension of the present utility model.In every case with the utility model structure or intimate technological scheme, all at protection domain of the present utility model.
