Abstract
The utility model discloses a kind of low pressure loss ball check valve, including valve body, ball and joint, ball is arranged in the cavity of valve body, the port of export of the dovetail connector on the right side of valve body, a circle non-return ring is provided with the inwall of valve body, non-return ring is more than the internal diameter of non-return ring and less than the external diameter of non-return ring close to the sealing surface that the one side of the port of export is ramp structure, the diameter of ball, the lattice block piece with through hole, positioned at connecting portion center is provided with joint, ball is located between non-return ring dative block piece.The utility model is smaller on the influence of the circulation footpath of whole medium, non-return time short low pressure loss.
Description
Technical field
The utility model is related to a kind of check-valves, more particularly, to a kind of low pressure loss ball check valve.
Background technology
Check-valves is also known as check valve or non-return valve, and its effect is to prevent the medium in pipeline from flowing backwards, and opening and closing element leans on medium flow field
Dynamic and strength is voluntarily turned on and off, to prevent the valve that medium flows backwards check-valves.Check-valves belongs to automatic valve class, main to use
In on the pipeline of medium one-way flow, only medium is allowed to be flowed to a direction, to try to avert accidents.
Due to the market demand, the application of present gas heater has been widely used, but is installing and safeguarding combustion
When gas water heater（Gas heater has three interfaces, respectively water inlet end, inlet end, water side）, due to installing and tieing up
Reason, the port of export for being connected to water heater of gas inlet end mistake, 0.2Mpa hydraulic pressure winks when causing to open water heater such as repair
Between entered gas pipeline by water heater；Cause gas pipeline and branch water inlet tube.Even it can make whole section branch road when serious
Gas pipeline is intake；User can not normally use combustion gas；Gas company wants section to stop the supple of gas or steam to draw water and suppressing supply, causes unnecessary
Heavy losses.
Because the combustion gas used belongs to low pressure（2-3Kpa）Source of the gas, common check-valves needs to consume excessive pressure to close
Sealing acting could be used, and crushing, which can excessively prevent pipeline export gaseous-pressure, to be caused tolerance not enough from meeting user's request or beat
Non-ignitable phenomenon.So being badly in need of the check-valves of a low pressure loss.
The content of the invention
Technical problem to be solved in the utility model, which is to provide a kind of circulation footpath on whole medium, influences smaller, non-return
The ball check valve of time short low pressure loss.
The utility model solve the technical scheme that is used of above-mentioned technical problem for：A kind of low pressure loss ball check valve, bag
Include valve body, ball and joint, described ball is arranged in the cavity of valve body, dovetail connector the right side of valve body the port of export,
It is provided with a circle non-return ring on the inwall of described valve body, described non-return ring is ramp structure close to the one side of the port of export
Sealing surface, the diameter of described ball, which is more than the internal diameter of non-return ring and is less than in the external diameter of non-return ring, described joint, to be provided with
Lattice block piece with through hole, positioned at connecting portion center, described ball is located between non-return ring dative block piece.
The further preferred scheme of the utility model：Described ball is NBR balls.Using NBR balls, the pressure loss is low
In 100pa.When right-hand member injects 0.2Mpa hydraulic pressure, it can move ball with moment, sphere contacts to sealing surface, which are played back, only to be acted on.
The further preferred scheme of the utility model：Described joint includes connecting portion and is arranged on connecting portion outer ring
Limit baffle ring, described connecting portion is stretched into valve body, is fixedly connected with the valve body, and described limit baffle ring is located at connecting portion close to interior
The end of side.It is fixedly connected with the valve body by connecting portion, by limit baffle ring come the limit to valve body, connecting portion link position
Position.
The further preferred scheme of the utility model：The inwall of described connecting portion is ramp structure.Fluid is reduced to pass through
The resistance received during the utility model.
Compared with prior art, the utility model has the advantage of during normal use, fluid flows by from left to right
Out-of-date, ball, due to the effect of lattice block piece, is that will not touch the inwall of joint, that is to say, that fluid is being capable of just normal open
Cross.Circulation footpath influence on whole medium is smaller, and the cross-sectional area and pipeline drift diameter of flow of media are basically identical.But working as has stream
Body from the right side turn left by when, due to ball light weight, moment can cause ball top to the sealing surface of valve body, moment non-return.To logical
The pressure medium demand crossed is small, and the corresponding crushing entirely managed is low, conventional below 500pa, the utility model be 150Pa with
Under.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawings, the utility model is described in detail.
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only to explain this
Utility model, is not used to limit the utility model.
As shown in Figure 1：A kind of low pressure loss ball check valve, including valve body 1, ball 2 and joint 3, ball 2 are arranged on valve body
In 1 cavity, joint 3, which is engaged on the port of export on the right side of valve body 1, the inwall of valve body 1, is provided with a circle non-return ring 4, non-return
Ring 4 is more than the internal diameter of non-return ring 4 and less than only close to the sealing surface 5 that the one side of the port of export is ramp structure, the diameter of ball 2
The lattice block piece 6 with through hole, positioned at the center of connecting portion 7 is provided with the external diameter of winding 4, joint 3, ball 2 is located at the dative of non-return ring 4
Between block piece 6.
Ball 2 is NBR balls.Joint 3 includes connecting portion 7 and is arranged on the limit baffle ring 8 of the outer ring of connecting portion 7, connection
Portion 7 stretches into valve body 1, is fixedly connected with valve body 1, and limit baffle ring 8 is located at end of the connecting portion 7 close to inner side.Connecting portion 7 it is interior
Wall is ramp structure.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Any modifications, equivalent substitutions and improvements made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
