Abstract
The utility model discloses a visual one-way valve for an injector, which comprises a valve body and a sealing structure movably matched with the valve body, wherein the sealing structure is arranged into a movable sealing column and a sealing ring movably arranged on the movable sealing column; the movable sealing column higher than the top surface of the connecting port is arranged in the valve body, so that the movable sealing column can be observed to move up and down in normal work; when the movable sealing column is stuck on the inner side wall of the valve body and cannot work, the movable sealing column is still, and the visual column can be directly and manually pressed to be separated from the valve body, so that the normal use is recovered, and the disassembly and the assembly are not needed.
Description
Technical Field
The utility model relates to a check valve field, especially a visual check valve for syringe.
Background
The check valve is widely applied in production and life, so the check valve can not be applied to viscous or sticky liquid, and a ball in the check valve can be stuck on an internal pipeline of the check valve after long-time use or not cleaned in time after use, so that the check valve can not work normally; in addition, in the prior art, whether the check valve normally operates or not can be observed by observing the water flow condition of the check valve, but the check valve cannot be determined to be in fault, each sealing point needs to be cleared, and even if the check valve cannot normally operate, the check valve needs to be repaired by being assembled and disassembled.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model aims to provide a visual one-way valve for an injector.
In order to achieve the purpose, the utility model discloses a following technical scheme, a visual check valve, including the valve body and with valve body clearance fit's seal structure, seal structure sets up to the movable seal post to and the activity sets up the sealing washer on the movable seal post, the movable seal post outside is provided with the spherical sealing face, the valve body inside wall respectively with sealing washer and spherical sealing face clearance fit.
Preferably, the movable sealing column is sequentially provided with a visual column, a spherical sealing surface and a spring stress column from top to bottom.
Preferably, the cross section of the valve body is in a convex shape, the top of the valve body is provided with a connector connected with a water pipe, and a guide convex ring is arranged on the outer side of the connector.
Preferably, the valve body inside wall is provided with the chamber that holds that corresponds visual post, sealing washer, spherical sealing surface and spring atress post respectively.
Preferably, the inner side wall of the valve body is provided with threads corresponding to the spring stress column.
Preferably, the top end of the visual column is higher than the top surface of the connecting port.
In the check valve technical field, with the foraminiferous base of valve body bottom surface screw-thread fit to and set up the reset spring that corresponds seal structure on foraminiferous base and be common technological means, consequently omit the structural description to base and reset spring in this application, on this basis, expand the theory of operation and the workflow of describing this application:
the connector is used for connecting a water inlet pipe, and water flows into the valve body of the one-way valve through the connector and flows out through the base with the hole; when water flows in, the water flow has acting force on the movable sealing column, so that the spring stress column compresses the reset spring; when water flow does not flow into the connecting port any more, the movable sealing column does not bear the acting force from the water flow, and the reset spring resets the movable sealing column.
When the connecting pipe connected with the connecting port is a transparent pipe, the top end of the visible column is higher than the top surface of the connecting port, on one hand, when water flows into the one-way valve body in a time interval, the visible column can be observed to move up and down in normal work, and whether the movable sealing column works effectively or not can be observed more conveniently; on the other hand, when the movable sealing column is stuck on the inner side wall of the valve body, the visual column can be directly and manually pressed to be separated from the valve body, and the valve can be recovered to be normally used without being disassembled and assembled.
The beneficial effects of the utility model are that: the movable sealing column is arranged in the valve body and is higher than the top surface of the connector, so that the movable sealing column can be observed to move up and down during normal work; when the movable sealing column is stuck on the inner side wall of the valve body and cannot work, the movable sealing column is still, and the visual column can be directly and manually pressed to be separated from the valve body, so that the normal use is recovered, and the disassembly and the assembly are not needed.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic cross-sectional structure diagram of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in figure 1, the visual one-way valve for the injector comprises a valve body 2 and a sealing structure movably matched with the valve body 2, wherein the sealing structure is a movable sealing column 4 and a sealing ring 3 movably arranged on the movable sealing column 4, a spherical sealing surface 42 is arranged on the outer side of the movable sealing column 4, and the inner side wall of the valve body 2 is movably matched with the sealing ring 3 and the spherical sealing surface 42 respectively.
At reset spring 5 activity in-process, because the route of the sealed post of activity 4 motion at every turn can produce certain deviation, lead to sealed face on the sealed post of activity 4 can't laminate with the check valve inside wall completely, consequently this application sets up sealed face into the sphere, makes it can laminate with the check valve inside wall in the activity process, reinforcing sealing performance.
Preferably, the movable sealing column 4 is sequentially arranged into a visible column 41, a spherical sealing surface 42 and a spring force bearing column 43 from top to bottom.
Preferably, 2 cross-sections of valve body set up to the type of protruding font, 2 tops of valve body set up to the connector 1 with water piping connection, the connector 1 outside is provided with direction bulge loop 11, and when the cover was equipped with the connecting pipe in the connector 1 outside, direction bulge loop 11 can prevent that the connecting pipe pine from taking off, also can prevent that rivers from flowing from the gap between connector 1 and the connecting pipe, reinforcing practicality.
Preferably, the inner side wall of the valve body 2 is provided with accommodating cavities respectively corresponding to the visible column 41, the sealing ring 3, the spherical sealing surface 42 and the spring stress column 43, so that the movable matching performance of the valve body 2 and the sealing structure is enhanced.
Preferably, the inner side wall of the valve body 2 is provided with a thread corresponding to the spring stress column 43, so that the valve body 2 is conveniently installed on the base in a threaded manner.
Preferably, the top end of the visual column is higher than the top surface of the connecting port 1, on one hand, when water flows into the one-way valve body in a time interval, the visual column can be observed to move up and down in normal work, and whether the movable sealing column works effectively or not can be observed more conveniently; on the other hand, when the movable sealing column is stuck on the inner side wall of the valve body, the visual column can be directly and manually pressed to be separated from the valve body, and the normal use is recovered without dismounting.
What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
