Abstract
The utility model discloses a check valve. The check valve comprises a valve body, a connector, a valve plug and a spring, wherein the valve body is axially connected with the connector via a screw; the valve plug and the spring are arranged in a through hole of the valve body; a slide bar is arranged at one end of the valve plug, is inserted in the through hole of the valve body and can slide axially; the cross section of the slide bar is provided with at least a notch; a plug is arranged at the other end of the valve plug; the slide bar is sleeved with the spring; a through hole of the connector is plugged by the plug via elastic pressure. The check valve has good using effects.
Description
Technical field
The utility model belongs to a kind of valve field, is specifically related to a kind of one-way valve.
Background technique
As shown in Figure 4, traditional manually operated valve is all generally the spool of ball structure is realized runner circulation and obturation by spring, but this structure makes ball easily and spring departs from, and its track departs from duct, thereby cannot realize the circulation of runner with inaccessible, so using effect is not good.
Model utility content
(1) technical problem that will solve
The technical problems to be solved in the utility model is to improve circulation and the inaccessible function of spool to runner in one-way valve.
(2) technological scheme
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of one-way valve, comprises valve body, joint, spool and spring; Described valve body with joint screw axis to being connected, described spool and spring are arranged in the through hole of valve body, described spool one end is the sliding bar that cross section has a breach at least, described sliding bar is plugged in the through hole of valve body and can slides axially, the other end is plug, described spring housing is connected on sliding bar, makes the through hole of plug packed joint by elastic pressure.
The notch geometry of described sliding bar is fan-shaped.
One end of described plug is provided with sealing head and screw, and described sealing head is axially disposed within on plug, and is fixedly connected with by screw, and described sealing head coordinates the through hole of packed joint.
The material of described spool is stainless steel.
Described joint through hole be provided with circular arc chamfering, described sealing head and circular arc chamfering coordinate and contact.
(3) beneficial effect
One-way valve of the present utility model, the through hole by spool by joint is set and removable, thereby prevent spool dislocation, its motion track departs from through hole, has therefore improved using effect.
Brief description of the drawings

Fig. 2 is the sectional view of 2 breach of A-A in Fig. 1;
Fig. 3 is the sectional view of 1 breach of A-A in Fig. 1;
Fig. 4 is the structural representation of the one-way valve of conventional art;
In figure, 1 is that valve body, 2 is that joint, 3 is that spool, 4 is that spring, 5 is that sliding bar, 6 is that plug, 7 is that through hole, 8 is that breach, 9 is that sealing head, 10 is that screw, 11 is circular arc chamfering.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
A kind of one-way valve as shown in Figure 1-Figure 3, comprises valve body 1, joint 2, spool 3 and spring 4; Described valve body 1 with joint 2 screw axis to being connected, described spool 3 and spring 4 are arranged in the through hole 7 of valve body 1, described spool 3 one end are the sliding bar 5 that cross section has a breach 8 at least, by breach 8, make to form duct between breach 8 and the through hole 7 of valve body 1, described sliding bar 5 is plugged in the through hole of valve body 1 and can slides axially, and the other end is plug 6, described spring 4 is socketed on sliding bar 5, makes the through hole 7 of plug 6 packed joints 2 by elastic pressure.After liquid flows into the through hole 7 of joint 2, contact and back down with plug 6, spool 3 is moved backward along the through hole 7 of valve body 1, thereby Gu Yetiliurukongdao enters the through hole 7 of valve body 1, when after flow of fluid, described spring 4 resets, and described spool 3 axially resets along through hole 7, because spool 3 is plugged in through hole 7 all the time, therefore can prevent spool dislocation, its motion track departs from through hole, has therefore improved using effect.
The breach 8 of described sliding bar 5 is shaped as fan-shaped.
One end of described plug is provided with sealing head 9 and screw 10, the material of sealing head 9 is rubber, and described sealing head is axially disposed within on plug, and is fixedly connected with by screw 10, described sealing head 9 coordinates the through hole 7 of packed joint 2, improves the sealing effect of sealing head 9 by this structure.
The material of described spool 3 is stainless steel.
Described joint 2 through hole 7 be provided with circular arc chamfering 11, described sealing head 9 and circular arc chamfering 11 coordinates and contacts, and increased surface of contact, this structure can prevent that sealing head 9 from damaging, and has also further improved sealing effect.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
