Description
Technical field
The utility model is related to a kind of check-valves, more particularly to a kind of check-valves on vertical pipe.
Background technology
Check-valves refers to be flowed in itself by medium and automatic open and close flap, for preventing the valve of medium refluence, also known as
Non-return valve, check valve, reflux valve and counterbalance valve.Check-valves belongs to a kind of automatic valve, and its Main Function is to prevent medium from falling
Flow, prevent pump and drive motor from inverting, and vessel media is released.
The structure of traditional check-valves as shown in figure 1, the movement locus of its flap 1 is rotate-stationary mode, while in valve body
Cavity also due to this motion mode can compare it is big, the volume of corresponding whole valve body than larger, and can use this
The check-valves of movement locus is planted, it is only used for the installation on horizontal pipe when being installed, and is carried out on vertical pipe
During installation, the flap of this movement locus due to the influence of medium, and can cause to open and close difficulty, therefore, have for installation direction
Certain limitation.
Utility model content
The technical problems to be solved in the utility model be to provide a kind of small volume, can 360 ° of directions arbitrarily install for hanging down
Check-valves on straight pipeline.
In order to solve the above technical problems, the technical solution of the utility model is：A kind of check-valves on vertical pipe,
Its innovative point is：Including
One valve body, the valve body includes upper valve body setting up and down, lower valve body, has one to hold upper valve body in the upper end of lower valve body
Embedded groove, while there is the projection in an insertion lower valve body groove, the upper and lower common shape of valve body in the lower end of upper valve body
Into the passage for holding flow of media；
One opening/closing component, the opening/closing component is located in valve channel including one and can be reciprocal along the bearing of trend of passage
The valve rod of motion, one are arranged on the flap of valve rod lower end and a valve seat being arranged in lower valve body, the sealing surface of the flap
Sealing surface with valve seat is collectively forming sealing pair；
One positioning component, the positioning component includes a positioning disk for being used to carry out valve rod location and installation, the positioning disk
Install in lower valve body and be located between the projection of upper valve body and the groove of lower valve body, have one to hold valve in the centre of positioning disk
The through hole that bar is passed through, while the surrounding positioned at through hole on positioning disk is additionally provided with what several ring-shaped distributed appearance media passed through
Runner；
One reset assembly, the reset assembly includes a back-moving spring for being sleeved on valve rod outer end, the two of the back-moving spring
End is against the end of positioning disk and the end of flap respectively.
The utility model has the advantage of：In the utility model, it is improved by the structure to traditional check-valves,
The movement locus of flap is changed into along the linear motion of channel direction by traditional rotary motion, so as to pipeline installation side can not be received
To limitation, can arbitrarily be installed with 360 ° of directions, overcoming traditional structure has the limitation of installation direction, sealed reliable, Er Qiefa
The movable cavity that valve needs can also reduce, and corresponding whole valve volume can also diminish.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the schematic diagram of traditional check-valves.
Fig. 2 is the schematic diagram of the check-valves on vertical pipe of the present utility model.
Specific embodiment
The following examples can make professional and technical personnel that the utility model is more fully understood, but therefore will not
The utility model is limited among described scope of embodiments.
A kind of super-silent negative-pressure air fan as shown in Figure 2, including
One valve body, the valve body includes upper valve body 5 setting up and down, lower valve body 1, has one to hold in the upper end of lower valve body 1
The groove of the insertion of valve body 5, while there is the projection in an insertion groove of lower valve body 1, upper valve body 5, lower valve in the lower end of upper valve body 5
Body 1 is collectively forming the passage 7 for holding flow of media.
One opening/closing component, the opening/closing component is located in valve channel 7 including one and can be reciprocal along the bearing of trend of passage 7
The valve rod 6, one of motion is arranged on the valve seat 8 that the flap 2 and of the lower end of valve rod 6 is arranged in lower valve body 1, the sealing of flap 2
Face is collectively forming sealing pair with the sealing surface of valve seat 8.
One positioning component, the positioning component includes a positioning disk 4 for being used to carry out valve rod 6 location and installation, the positioning disk 4
Install in lower valve body 1 and be located between the projection of the lower end of upper valve body 5 and the groove of the upper end of lower valve body 1, in the central part of positioning disk 4
Position has the through hole that an appearance valve rod 6 is passed through, while the surrounding positioned at through hole on positioning disk 4 is additionally provided with several distributions annular in shape
The runner 9 that passes through of appearance medium.
One reset assembly, the reset assembly includes a back-moving spring 3 for being sleeved on the outer end of valve rod 6, the two of the back-moving spring 3
End is against the end of positioning disk 4 and the end of flap 2 respectively.
It is improved by the structure to traditional check-valves, the movement locus of flap is changed into by traditional rotary motion
Along the linear motion of channel direction, so as to can not be limited by pipeline installation direction, can arbitrarily be installed with 360 ° of directions, overcome
The movable cavity that traditional structure has the limitation of installation direction, sealed reliable, and flap and needs can also reduce, corresponding whole valve
Door body product can also diminish.
It should be understood by those skilled in the art that, the utility model is not restricted to the described embodiments, above-described embodiment and
Principle of the present utility model simply is illustrated described in specification, on the premise of the utility model spirit and scope are not departed from,
