It is CN103090143A that State Intellectual Property Office discloses publication number on May 8th, 2013, patent name is the threeway in ceramic solar energy heat-collection system, the Patent Application Publication of elbow, it relates to the threeway in ceramic solar energy heat-collection system, the material of elbow, structure, purposes and usage, the fast fitting of existing threeway cast iron and the fast fitting of elbow cast iron all do not have interior step there is no the spacing interior step after pipeline inserts, when practical application, once insertion depth is deep, pipeline can seal or approach the outlet of sealing fluid, the turnover mouth of pipe external diameter of ceramic solar plate has certain error, adopt threeway or the elbow inside of rubber material manufacture to have pair influx pipe insertion depth to there is the interior step of position-limiting action, avoided the excessively dark possibility of influx pipe insertion depth, the tolerance differences that rubber material has the outside dimension of the welding thin-wall stainless steel of the various places as influx pipe of the turnover mouth of pipe external diameter of certain elasticity to ceramic solar plate, market purchasing, each plant produced has good adaptability.
Above-mentioned patent documentation, although there is such or such advantage, does not possess adaptive switched function, therefore the technological scheme of above-mentioned patent and the technological scheme of this patent are completely different.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of oil pipe with adaptive switched function adaptive switched threeway.
For achieving the above object, the technological scheme that the utility model adopts is:
The adaptive switched threeway of oil pipe, it is by circular tube shaped valve body, sealed cover, screw and ball sealer form, the upper end of described circular tube shaped valve body is female adapter, the lower end of circular tube shaped valve body is male connection, described female adapter is connected with the end thread of oil pipe respectively with male connection, screw is fixed on sealed cover in circular tube shaped valve body, sealed cover is provided with upper end liquid entering hole, described circular tube shaped valve body is provided with sidewall liquid entering hole and lower end liquid port, in described circular tube shaped valve body, be provided with the alley being communicated with sidewall liquid entering hole and upper end liquid entering hole, described ball sealer is located in alley, lower end liquid port is communicated with alley.
Described upper end liquid entering hole is located at the right side of the axis of circular tube shaped valve body, and described sidewall liquid entering hole is located on the left surface of circular tube shaped valve body.
The external diameter of described circular tube shaped valve body is identical with the external diameter of oil pipe.
Described circular tube shaped valve body and ball sealer are to be made up of stainless steel material.
The beneficial effects of the utility model: owing to adopting above-mentioned structural type, under the effect of hydraulic pressure, the feed liquor that can realize sidewall liquid entering hole and upper end liquid entering hole switches.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
In figure: 1, circular tube shaped valve body; 2, ball sealer; 3, sidewall liquid entering hole; 4, upper end liquid entering hole; 5, lower end liquid port; 6, alley; 7, axis; 8, female adapter; 9, male connection; 10, oil pipe; 11, oil pipe; 12, sealed cover; 13, screw.
Embodiment
As shown in Figure 1, the adaptive switched threeway of oil pipe, it is to be made up of circular tube shaped valve body 1, sealed cover 12, screw 13 and ball sealer 2, the upper end of described circular tube shaped valve body 1 is female adapter 8, the lower end of circular tube shaped valve body 1 is male connection 9, and described female adapter 8 is connected with the end thread of oil pipe 10 and oil pipe 11 respectively with male connection 9.The external diameter of described circular tube shaped valve body 1 is identical with the external diameter of oil pipe 10 and oil pipe 11.Screw 13 is fixed on sealed cover 12 in circular tube shaped valve body 1, sealed cover 12 is provided with upper end liquid entering hole 4, described circular tube shaped valve body 1 is provided with sidewall liquid entering hole 3 and lower end liquid port 5, in described circular tube shaped valve body 1, be provided with the alley 6 being communicated with sidewall liquid entering hole 3 and upper end liquid entering hole 4, described ball sealer 2 is located in alley 6, and lower end liquid port 5 is communicated with alley 6.Described upper end liquid entering hole 4 is located at the right side of the axis 7 of circular tube shaped valve body 1, and described sidewall liquid entering hole 3 is located on the left surface of circular tube shaped valve body 1.
Working principle: when liquid is in upper end liquid entering hole flows into circular tube shaped valve body, ball sealer seals sidewall liquid entering hole, when liquid is in sidewall liquid entering hole flows into circular tube shaped valve body, under hydraulic pressure, ball sealer is by the sealing of upper end liquid entering hole, and the liquid flowing in circular tube shaped valve body is all discharged from lower end liquid port; Ball sealer can not roll out from sidewall liquid entering hole and upper end liquid entering hole.Back out screw 13 sealed cover 12 is pulled down, can from alley, take out by ball sealer 2, sealed cover 12 adopts removable form, exactly for ball sealer being put into alley.
