Abstract
The utility model discloses a cut-off type plug. The cut-off type plug comprises a cylindrical body and a sealing part, one end of the sealing part is a cut-off plane, the other end of the sealing part is a sealing end, the cut-off plane of the sealing part is connected with one end of the cylindrical body, and the sealing end of the sealing part is a spherical surface. The cut-off type plug has the advantages that the sealing end of the cut-off type plug is the spherical surface, the spherical surface is in line contact sealing with the conical surface of an auxiliary hole, and the requirement for machining the sealing end of the cut-off type plug is lowered; the spherical surface has the self-alignment performance, and therefore the sealing end of the cut-off type plug can be sealed more reliably. Compared with an existing structure, the cut-off type plug is low in machining difficulty, high in production efficiency, low in cost and high in sealing reliability.
Description
Technical field
The utility model relates to a kind of screw plug device, especially relates to a kind of cutting type screw plug device.
Background technique
In Hydraulic Industry field, the application of screw plug is very extensive, and various hydraulic products all can be used.Screw plug generally includes cutting type screw plug and common screw plug, and common screw plug is detachable, but cost is higher, and cutting type screw plug is compared with common screw plug, and non-dismountable, cost is lower.Cutting type screw plug is mainly used in the various occasions that need sealing technology hole at present, is used for carrying out disposable sealing, does not need dismounting.
Existing cutting type screw plug is employing conical surface sealing structure generally, concrete structure as shown in Figure 1, its working principle is: screw plug is slowly screwed in auxiliary hole (conical surface tapped hole), when the screw plug conical surface contacts with the tapped hole conical surface, reach certain torque force, thereby produce enough shearing stress, at the section cut-out screw plug of cutting type screw plug.There is following problem in existing cutting type screw plug: the conical surface of cutting type screw plug contacts sealing with the conical surface employing face of auxiliary hole, this kind of sealing means has very high processing request to the conical surface of cutting type screw plug, cost is higher, and cutting type screw plug course of working easily produces substandard products, affect sealability reliability, increase leakage of oil probability.
Summary of the invention
Technical problem to be solved in the utility model is to provide that a kind of difficulty of processing is low, and cost is lower, and the high cutting type screw plug of sealing reliability.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of cutting type screw plug, comprise cylindrical body and sealed department, one end of described sealed department is section, the other end of described sealed department is sealed end, the section of described sealed department is connected with one end of described cylindrical body, and the sealed end of described sealed department is sphere.
Between described cylindrical body and described sealed department, be provided with joint, one end of described cylindrical body is connected by joint with the section of described sealed department.
Compared with prior art, the utility model has the advantage of by the sealed end of cutting type screw plug slowly lemon enter in auxiliary hole (conical surface tapped hole), when sealed end contacts with the auxiliary hole conical surface, reach certain torque force, thereby produce enough shearing stress, now the section of cutting type screw plug cuts off, and the sealed end of cutting type screw plug of the present utility model is sphere, between sphere and the conical surface of auxiliary hole, be line contact sealing, the processing request of the sealed end of cutting type screw plug is reduced; And sphere has self-alignment, the sealing of the sealed end of cutting type screw plug is more reliable like this, and the utility model is compared with existing structure, and difficulty of processing is lower, and manufacturing efficiency is higher, and cost is lower, and sealing reliability is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of the cutting type screw plug of prior art;
Fig. 2 is the structural representation of cutting type screw plug of the present utility model;
Fig. 3 is the plan view of cutting type screw plug of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
Embodiment: as shown in Figures 2 and 3, a kind of cutting type screw plug, comprises cylindrical body 1 and sealed department 2, one end of sealed department 2 is section 21, the other end of sealed department 2 is sealed end 22, and the section 21 of sealed department 2 is connected with one end of cylindrical body 1, and the sealed end 22 of sealed department 2 is sphere.
In the present embodiment, between cylindrical body 1 and sealed department 2, be provided with joint 3, one end of cylindrical body 1 is connected by joint 3 with the section 21 of sealed department 2.
Working principle of the present utility model is: by the sealed end of cutting type screw plug 22 slowly lemon enter in auxiliary hole 4 (conical surface tapped hole), when sealed end 22 contacts with auxiliary hole 4 conical surfaces, reach certain torque force, thereby produce enough shearing stress, now the section 21 of cutting type screw plug cuts off, the sealed end 22 of cutting type screw plug of the present utility model is sphere, between sphere and the conical surface of auxiliary hole 4, is line contact sealing.
Claims (2)
1. a cutting type screw plug, it is characterized in that comprising cylindrical body and sealed department, one end of described sealed department is section, and the other end of described sealed department is sealed end, the section of described sealed department is connected with one end of described cylindrical body, and the sealed end of described sealed department is sphere.
2. a kind of cutting type screw plug according to claim 1, is provided with joint between the cylindrical body described in it is characterized in that and described sealed department, and one end of described cylindrical body is connected by joint with the section of described sealed department.
