Abstract
The invention proposes an in-line check valve. The in-line check valve comprises a main body with a hollow channel, a conducting device, an inlet pipe with a first channel, and an outlet pipe with a second channel; the first channel and the second channel are respectively conducted with the hollow channel of the main body; the conducting device includes a spring and a steel ball; one side of the spring is fixedly connected with the steel ball, and the other end is fixedly connected with the inner wall of the outlet pipe; and the steel ball is arranged in the matched place of the first channel with the hollow channel, and is contacted with the inner wall of the first channel. The in-line check valve is reversely obstructed under pressure loss through controlling movement of the steel ball when passing through liquid currents, is excellent in sealing performance, is compact in structure, and is safe and reliable.
Description
Technical field
The present invention relates to check valve field, particularly relates to a kind of straight check valve.
Background technology
Check valve is also known as check-valves or non-return valve.For oil stream reverse flow is prevented in hydraulic system, or it is used for
Compressed air reverse flow is prevented in pneumatic system；Check valve only allows liquid in hydraulic system along a side
To flowing, and it is unable to reverse flow, it is desirable to be liquid little by the pressure loss afterwards, when reversely obstructed
Wait its sealing property to get well, pressure crosses conference causes its sealing property to be deteriorated, so that its work is not sufficiently stable
It is reliable, and cost of manufacture is also high.
The content of the invention
In view of the shortcomings of the prior art, it is an object of the invention to provide a kind of compact conformation, sealing
Good, the safe and reliable straight check valve of energy.
The technical scheme is that what is be achieved in that：A kind of straight check valve, which includes hollow channel
Main body, conducting device, the inlet tube for having first passage and the outlet for having second channel；The first passage
Turned on the hollow channel of main body with second channel respectively；The conducting device includes spring and steel ball, described
The side of spring is fixedly connected with steel ball, and the other end is fixedly connected with outlet inside pipe wall, and the steel ball is arranged on
Contact at the cooperation of first passage and hollow channel and with first passage inwall.
Further, internal diameter of the internal diameter of the first passage and second channel less than hollow channel.
Further, the straight check valve also includes the collar；The collar is arranged on and is socketed in main body
A kind of straight check valve of the present invention, by the movement for controlling steel ball so that pressure when liquid stream passes through
Under loss, reversely obstructed, good seal performance, its compact conformation and safe and reliable.
Description of the drawings
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below will be to implementing
Example or accompanying drawing to be used needed for description of the prior art are briefly described, it should be apparent that, describe below
In accompanying drawing be only some embodiments of the present invention, for those of ordinary skill in the art, do not paying
On the premise of going out creative labor, can be with according to these other accompanying drawings of accompanying drawings acquisition.
Fig. 1 is a kind of cross section structure diagram of straight check valve of the invention；
Side views of the Fig. 2 for Fig. 1.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clearly
Chu, it is fully described by, it is clear that described embodiment is only a part of embodiment of the invention, rather than
Whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not making creation
Property work under the premise of the every other embodiment that obtained, belong to the scope of protection of the invention.
As shown in figure 1, a kind of straight check valve, main body 9 which includes hollow channel, conducting device 10,
The inlet tube 4 for having first passage 6 and the outlet 1 for having second channel 7；The first passage 6 and second is logical
Road 7 is turned on the hollow channel 8 of main body 9 respectively；The conducting device 10 includes spring 5 and steel ball 3,
The side of the spring 5 is fixedly connected with steel ball 3, and the other end is fixedly connected with outlet inside pipe wall 71, described
Steel ball 3 is arranged at the cooperation of first passage 6 and hollow channel 8 and is contacted with first passage inwall 61.
A kind of internal diameter of above-mentioned straight check valve, the first passage 6 and second channel 7 is logical less than hollow
The internal diameter in road 8；The steel ball 3 will be connected on first passage inwall 61 and straight check valve sealing, because
The internal diameter of this first passage 6 is less than 8 internal diameter of hollow channel；There are enough spaces in the hollow channel 8
Steel ball 3 is allowed to float.
A kind of above-mentioned straight check valve, the straight check valve also include the collar 2；The collar 2 is arranged on
On the main body 9,2 outer ring structure of the collar is hexagon for socket.
Wherein, the main body 9, inlet tube 4, outlet 1, steel ball 3 and the collar 2 before assembly, all enter
Went plating white zine and passivation so as to goodlooking, and can prevent aging.
When use, liquid stream enters first passage 6 from the entrance of inlet tube 4 and forms certain pressure
Steel ball 3 is inwardly advanced into a segment distance and is turned on hollow channel 8, then liquid stream is along hollow channel 8
Into second channel 7, last liquid stream flows out outlet 1 and enters external equipment.
A kind of straight check valve of the present invention, by the movement for controlling steel ball so that pressure when liquid stream passes through
Under loss, reversely obstructed, good seal performance, its compact conformation and safe and reliable.
Presently preferred embodiments of the present invention is the foregoing is only, it is not to limit the present invention, all at this
Within bright spirit and principle, any modification, equivalent substitution and improvements made etc. should be included in this
Within bright protection domain.
