Abstract
The invention discloses a polytetrafluoroethylene valve clack assembling device which comprises a connecting rod and a force transmission cylinder. One end of the connecting rod is fixedly connected with the upper end of the force transmission cylinder which is in a hollow cylinder shape. The lower end face of the force transmission cylinder is provided with two symmetrical concave arcs. The two symmetrical concave arcs and protrusions in the middle of the surface of a valve clack are matched in shape. The arc faces of the two symmetrical concave arcs are in complete contact with the protrusions in the middle of the surface of the valve clack. The connecting rod is fixed on a power mechanism. The polytetrafluoroethylene valve clack assembling device has the advantages that compared with the prior art, an existing machining procedure and an existing machining mode do not need to be changed, extra training for an operator is of no need, production cost does not need to be increased, the stress area of the assembling device and the valve clack is increased, the resistance performance of the valve clack is effectively improved, the structure is simple, manufacturing is convenient, and application and promotion in the industry can be well achieved.
Description
Technical field
The invention belongs to centre-pivoted butterfly valve processing technique field, relate in particular to a kind of polytetrafluoroethylene (PTFE) flap assembling device.
Background technology
Centre-pivoted butterfly valve is a kind of parts that are used for realizing pipe-line system break-make and flow-control, in many fields such as oil, chemical industry, metallurgy, water power, obtains applying very widely.The architectural feature of centre-pivoted butterfly valve is that rotating shaft core, butterfly plate center, body center are on same position.
Flap is a vitals of centre-pivoted butterfly valve always, and traditional flap is metal manufacture, and the installation of metal flap often adopts and utilizes the mounting means in Metallic rod jacking valve seat.Development along with centre-pivoted butterfly valve industry, for adapting to the flap of various application scenarios, also produced out, comprising the flap that utilizes polytetrafluoroethylene (PTFE) to make, yet, because the particularity of polytetrafluoroethylene (PTFE) flap material adopts traditional flap mounting means, may cause cut to flap surface, destroy even completely, and then cause the wasting of resources and cost to increase.
It is in centre-pivoted butterfly valve industry, to expect the technical barrier of solution that how that the flap of polytetrafluoroethylene (PTFE) manufacture is quick, safety is assembled on valve seat always.
Summary of the invention
The object of this invention is to provide a kind of polytetrafluoroethylene (PTFE) flap assembling device, with solve in prior art, exist can not the flap of polytetrafluoroethylene (PTFE) manufacture is quick, safety be assembled to the problem on valve seat.
For realizing object of the present invention, the invention provides a kind of polytetrafluoroethylene (PTFE) flap assembling device, described assembling device comprises connecting rod and power transmission cylinder, described connecting rod one end is fixedly connected with described power transmission cylinder upper end, it is hollow barrel-type that described power is transmitted cylinder, its lower surface is with two sections of symmetrical concave arcs, the shape of described two sections of symmetrical concave arcs matches with the boss shapes at middle part, described flap surface, and the cambered surface of described two sections of symmetrical concave arcs contacts completely with the lug boss at middle part, described flap surface; Described connecting rod is fixed on actuating unit.
Wherein, described actuating unit is hydraulic cylinder or pneumatic cylinder.
Beneficial effect of the present invention is, compared with the prior art, without changing existing manufacturing procedure and processing mode, to operating personnel without additionally training, without increasing production cost; Increase the lifting surface area of assembling device and flap, effectively improved the drag performance of flap; Simple in structure, easy to make, be conducive to industrially apply.
Accompanying drawing explanation
Fig. 1 is structural representation a of the present invention;
Fig. 2 is structural representation b of the present invention;
Fig. 3 is structural representation c of the present invention;
In figure, 1-connecting rod, 2-power is transmitted cylinder.
The specific embodiment
In order to make object of the present invention, technical scheme and beneficial effect clearer, below in conjunction with embodiment, the present invention is further elaborated.Should be understood to specific embodiment described herein only in order to explain the present invention, be not limited to protection scope of the present invention.
Fig. 1, Fig. 2, Fig. 3 are respectively and observe from different perspectives structural representation of the present invention.
As shown in Figure 1, Figure 2, Figure 3 shows, the invention provides a kind of polytetrafluoroethylene (PTFE) flap assembling device, with solve in prior art, exist can not the flap of polytetrafluoroethylene (PTFE) manufacture is quick, safety be assembled to the problem on valve seat.
The invention provides a kind of polytetrafluoroethylene (PTFE) flap assembling device, described assembling device comprises connecting rod and power transmission cylinder, described connecting rod one end is fixedly connected with described power transmission cylinder upper end, it is hollow barrel-type that described power is transmitted cylinder, its lower surface is with two sections of symmetrical concave arcs, the shape of described two sections of symmetrical concave arcs matches with the boss shapes at middle part, described flap surface, and the cambered surface of described two sections of symmetrical concave arcs contacts completely with the lug boss at middle part, described flap surface; Described connecting rod is fixed on actuating unit.
Wherein, described actuating unit is hydraulic cylinder or pneumatic cylinder.
When using, described connecting rod is fixed on actuating unit, also can utilizes artificial strike that power is provided, the cambered surface of two sections of symmetrical concave arcs contacts with the bossing face at middle part, flap surface completely, increase lifting surface area, then, provide power that described flap is squeezed in valve seat, the inside at middle part, flap surface is rotating shaft, this location comparison is firm, utilize this position, can be stressed even, more guaranteed the security of processing.
Beneficial effect of the present invention is, compared with the prior art, without changing existing manufacturing procedure and processing mode, to operating personnel without additionally training, without increasing production cost; Increase the lifting surface area of assembling device and flap, effectively improved the drag performance of flap; Simple in structure, easy to make, be conducive to industrially apply.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
