Abstract
The utility model discloses a check valve, which comprises a valve body (1), a spring (2) and a ball spool (3). One end of the spring (2) is connected with the valve body (1), and the other end of the spring (2) is connected with the ball spool (3). An oil outlet channel (4) is arranged on the valve body (1). The check valve further comprises a retaining block (5) for abutting against the ball spool (3). The retaining block (5) and the valve body (1) are connected in detachable mode. The use cost of the check valve is low.
Description
Technical field
The utility model relates to the parts on a kind of hydraulically balanced valve, specifically is a kind of one-way valve.
Background technique
The one-way valve of existing technology comprise be located in the valve piece through hole and with spherical valve core, spring and valve body that valve piece inwall offsets, be provided with axial hole in the described valve body; One end of said spring is connected with valve body, and the other end of said spring is connected with spherical valve body.There is following defective in the one-way valve of said structure in the using process of reality: because the rigidity of spherical valve body is strong; And the poor rigidity of valve piece; Therefore use is prone to make the wearing and tearing of valve piece and causes one-way valve to lose efficacy for a long time, so just necessary replacing valve piece, thereby the increase that brings user cost.
The model utility content
The technical problem that the utility model will solve is, overcomes the defective of above existing technology, provides a kind of user cost low one-way valve.
The technological scheme of the utility model is, a kind of one-way valve is provided, and comprises valve body, spring, spherical valve core; One end of said spring is connected with valve body, and the other end of said spring is connected with spherical valve body; Described valve body is provided with oil discharge passage; It comprises that also one is used for the block that offsets with spherical valve core, is provided with an axial oil inlet passage in the described block; Described block is removable the connection with valve body.
After adopting above structure, the utility model compared with prior art has the following advantages:
Be provided with in the utility model one-way valve and be used for the block that offsets with spherical valve core, therefore avoided offseting of spherical valve body and valve piece, only use after the wearing and tearing more that shift block gets final product therefore for a long time, so user cost is very low.
As improvement, described three oil discharge passages are evenly distributed on the outer peripheral surface of valve body, have guaranteed the oil pump capacity that one-way valve is bigger like this.
Description of drawings
Fig. 1 is the structural representation of the utility model one-way valve.
Fig. 2 is the structural representation of the utility model one-way valve valve body.
Shown in the figure 1, valve body, 2, spring, 3, spherical valve body, 4, oil discharge passage, 5, block, 6, oil inlet passage.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
Like Fig. 1, shown in Figure 2, a kind of one-way valve of the utility model comprises valve body 1, spring 2, spherical valve core 3; One end of said spring 2 is connected with valve body 1, and the other end of said spring 2 is connected with spherical valve body 3; Described valve body 1 is provided with oil discharge passage 4; It comprises that also one is used for the block 5 that offsets with spherical valve core 3, is provided with an axial oil inlet passage 6 in the described block 5; Described block 5 is removable the connection with valve body 1, and in the present embodiment, block 5 is a snapping with valve body 1.
The quantity of said oil discharge passage 4 is three; Described three oil discharge passages 4 are evenly distributed on the outer peripheral surface of valve body 1, and oil discharge passage 4 is on the axial direction.
Below only be described, but can not be interpreted as it is restriction claim with regard to the most preferred embodiment of the utility model.The utility model is not limited only to above embodiment, and its concrete structure allows variation.In every case the various variations of in the protection domain of the utility model independent claims, being done are all in the protection domain at the utility model.
Claims (2)
1. an one-way valve comprises valve body (1), spring (2), spherical valve core (3); One end of said spring (2) is connected with valve body (1), and the other end of said spring (2) is connected with spherical valve body (3); Described valve body (1) is provided with oil discharge passage (4); It is characterized in that: it comprises that also one is used for the block (5) that offsets with spherical valve core (3), is provided with an axial oil inlet passage (6) in the described block (5); Described block (5) is removable the connection with valve body (1).
2. one-way valve according to claim 1 is characterized in that: the quantity of said oil discharge passage (4) is three; Described three oil discharge passages (4) are evenly distributed on the outer peripheral surface of valve body (1).
