Abstract
The invention provides a kind of controllable check valve, including valve body, several backstops and swivel joint, several described backstops lay respectively at the corresponding opening part of described valve body, when the sealed end of backstop stretches into corresponding opening, it can be sealed, it is attached by elastic construction between other end base and described valve body inner shell or the base of another backstop of backstop, wherein there is the external channel that one or more described opening communicates therewith not coaxial, the external channel of this opening is provided with corresponding swivel joint, when swivel joint rotates in external channel, the sealed end of backstop with opening fitted seal can be touched, and by valve inner described in described backstop sealed end fight back, make seal failure.The invention provides the benefit that: when running into check-valves and needing to release liquid, it is only necessary to rotates outside handle, makes seal failure, at this moment just can let the liquid out, the state of change non-return, satisfied being actually needed in particular cases.
Description
Technical field
The invention relates to a kind of check-valves, especially relates to a kind of controllable check valve.
Background technology
Existing check-valves major part can control the liquid flowing in some direction well, can only flow to can not flow out in the direction, but sometimes in order to easy to maintenance, or releasing hydrops, there will be the situation needing to be released by the liquid of the direction, at this moment, common check-valves all can not solve this problem, it is impossible to meets being actually needed in particular cases.
Innovation and creation content
The purpose of the invention is to provide a kind of simple in construction, safe and reliable controllable check valve.
nullThe technical scheme of the invention is: a kind of controllable check valve，Including valve body、Several backstops and swivel joint，Several described backstops lay respectively at the opening part that described valve body is corresponding，The sealed end of described backstop matches with corresponding opening shape，When this end stretches into corresponding opening，It can be sealed，It is attached by elastic construction between other end base and described valve body inner shell or the base of another backstop of described backstop，Wherein there is the external channel that one or more described opening communicates therewith not coaxial，This opening out-of-alignment external channel is provided with corresponding swivel joint，Described swivel joint can rotate in external channel，Described swivel joint is provided with an eccentric lobe near one end of opening，When described swivel joint rotates in external channel，Described eccentric lobe can touch the sealed end of the backstop with opening fitted seal，And by valve inner described in described backstop sealed end fight back，Make seal failure.
Preferably, described swivel joint is for being removably mounted on described valve body.
Preferably, described swivel joint also includes the rotary body fixing with eccentric lobe, and described eccentric lobe is not coaxial with described rotary body, and described eccentric lobe is the cylindrical structure of the radius partial application obliquely along end face, and other end and described rotary body are fixed.
Preferably, the base dimensions of described backstop is more than the size of respective openings, and when the sealed end of described backstop stretches into corresponding opening, described base will be stuck in corresponding opening inner side, and form sealing by sealing member with described valve interior wall.
Preferably, described swivel joint is provided with hollow channel, with the channel connection in described valve body.
The invention has the advantage that and has the benefit effect that
Owing to adopting technique scheme, when running into check-valves and needing to release liquid, have only to the handle outside rotating, making described swivel joint drive eccentric lobe to rotate, described eccentric lobe can touch the sealed end of the backstop with opening fitted seal, and by valve inner described in described backstop sealed end fight back, make seal failure, at this moment just can let the liquid out, change the state of non-return, meet being actually needed in particular cases.
Accompanying drawing explanation
Fig. 1 is the structural representation of the invention；
Fig. 2 is the structural representation of swivel joint in the invention；
Fig. 3 be in the invention eccentric lobe along Fig. 2 M to structural representation.
Detailed description of the invention
Below in conjunction with the drawings and the specific embodiments, the invention is described further.
Such as Fig. 1, shown in 2, the invention includes valve body 1, two backstops and swivel joint, said two backstop lays respectively at opening A2 and the opening B3 place of described valve body 1, the sealed end 4 of described backstop matches with corresponding opening shape, when this end stretches into corresponding opening, it can be sealed, it is attached by spring between the base of one of them backstop and the base of another backstop, or the base of two backstops is all connected respectively through the spring inner shell with described valve body 1 or the connector that is fixed on inner shell, backstop is made to be subject to the trend to the motion of respective openings direction, opening can be answered to seal by automatic phasing.
The external channel that described opening A2 communicates therewith is not coaxial, described swivel joint is arranged in the passage outside described opening A2, described swivel joint can rotate in the channel, described swivel joint is provided with an eccentric lobe 6 near one end of opening A2, when described swivel joint rotates in passage, described eccentric lobe 6 can touch the sealed end 4 of the backstop with opening A2 fitted seal, and valve body 1 described in described backstop sealed end 4 fight back is internal, makes seal failure.
As shown in Figure 3, described swivel joint also includes the rotary body 7 fixing with eccentric lobe 6, described eccentric lobe 6 is not coaxial with described rotary body 7, and described eccentric lobe 6 is the cylindrical structure of the radius partial application obliquely along end face, and other end is fixed with described rotary body 7.When swivel joint rotates, described eccentric lobe 6 will contact with sealed end 4 gradually, and presses gradually, and sealed end 4 heads in respective openings the most at last, makes seal failure.
The base 5 of described backstop is sized larger than respective openings A2 or the size of opening B3, when stretching into corresponding opening A2 or opening B3 when the sealed end 4 of described backstop, described base 5 will be stuck in inside corresponding opening A2 or opening B3, and form sealing by packing ring with described valve body 1 inwall.
Described swivel joint is connected with outer handle, can be externally controlled the rotation of described swivel joint.
Described swivel joint is provided with hollow channel, the channel connection with in described valve body 1, facilitates liquid to flow.
When normally using, liquid can only enter from the passage outside opening A2 or opening B3, it is impossible to flows out.When running into check-valves and needing to release liquid, have only to the handle outside rotating, described swivel joint is made to drive eccentric lobe to rotate, described eccentric lobe can touch the sealed end of the backstop with opening A fitted seal, and by valve inner described in described backstop sealed end fight back, make seal failure, at this moment just can let the liquid out, change the state of non-return, meet being actually needed in particular cases.
The invention has been described in detail by above example, but described content is only the preferred embodiment of the invention, it is impossible to be considered the practical range for limiting the invention.All equalizations made according to the invention application range change and improvement etc., all should still belong within the patent covering scope of the invention.
