Description
Technical field
The utility model relates to rapid pipe joint technical field, particularly a kind of rapid pipe joint spool.
Background technique
Rapid pipe joint is a kind of quick connection or disconnects the device that pipeline realizes fast assembling-disassembling, is widely used in the field such as building, industrial and mineral hydraulic tools, oil, metallurgy, water power, boats and ships and engineering machinery.Existing a kind of rapid pipe joint is made up of negative joint and male connector, the inside of negative joint and male connector is respectively equipped with spool, described spool one end is respectively equipped with O RunddichtringO, negative joint housing circumference uniform distribution one group of steel ball, change female connector body circumference uniform distribution steel ball center of circle size by the mobile of outer lock set, lock or exit male connector.When pipeline disconnects, the housing of negative joint housing and male connector is formed with the O RunddichtringO on the spool of its inside and spool respectively and seals, hinder fluid flow.When pipeline needs to connect, promoting outer lock set pushes in negative joint by male connector, and male connector unclamps overcoat after inserting, and overcoat returns to original position locking male connector by contained spring, pipeline connects, and fluid circulates between negative joint housing and spool, between male connector housing and spool.
In above-mentioned rapid pipe joint spool, because O RunddichtringO is frequently by fluid scouring, cause O RunddichtringO easily to be washed out by fluid, affect the reliability that rapid pipe joint uses.Existing O RunddichtringO is generally nitrile rubber, and wear-resisting property is limited and elasticity is poor, does not have enough resiliently deformable spaces during the work of O RunddichtringO, and O RunddichtringO easily irreversible deformation occurs after using a period of time, causes sealing effect poor.
Summary of the invention
In order to overcome the defect of prior art, the utility model provides following technological scheme:
A kind of rapid pipe joint spool, it comprises insert body, described insert body upper end is provided with valve seat groove, insert body lower end is provided with step one from bottom to top successively, step two and step three, groove is formed between step one and step two, seal ring is provided with in described groove, the outside of seal ring is provided with seal ring protective sleeve, described seal ring protective sleeve upper end is sleeved on the outside of step one and step two, the lower end inside of seal ring protective sleeve is provided with two continuous print step surfaces, the outside of described seal ring upper end is provided with the projection matched with above-mentioned two continuous print step surfaces, described step one upper-end surface is provided with groove, described seal ring lower end is provided with the triangular hill with above-mentioned fit depressions, curve bath is provided with inside described seal ring, outside described seal ring, lower end is provided with a chamfering.
Further, outside described seal ring, the chamfering of lower end is 45 degree.
Further, described seal ring adopts urethane rubber material.
Further, described seal ring protective sleeve is withheld on step one and step two by eight equal parts mould, and withholds into step two 0.5mm.
Further, described seal ring protective sleeve adopts iron material matter to make.
The beneficial effect that the utility model brings is:
1, owing to being provided with seal ring protective sleeve, and the continuous step surface of seal ring protective sleeve lower end inside is sleeved on the continuous step surface of seal ring upper end, the triangular hill of seal ring lower end is installed in the groove of step one upper-end surface, therefore seal ring is not easy to be washed out by fluid, improves the reliability of rapid pipe joint work;
2, described seal ring is urethane rubber, improve the wear resistance of seal ring, resistance to pressure and elasticity, distortion when space between the triangular hill of the curve bath inside seal ring and the space of groove and seal ring lower end and the groove of step one works to seal ring provides space, easily shape is recovered, therefore good sealing effect after making sealed ring deformation.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the structure enlarged diagram of part A in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
As Fig. 1, shown in Fig. 2, a kind of rapid pipe joint spool, it comprises insert body 1, described insert body upper end is provided with valve seat groove 2, insert body lower end is provided with step 1 from bottom to top successively, step 24 and step 35, groove 6 is formed between step one and step two, seal ring 7 is provided with in described groove, the outside of seal ring 7 is provided with seal ring protective sleeve 8, described seal ring protective sleeve 8 upper end is sleeved on the outside of step 1 and step 24, the lower end inside of seal ring protective sleeve 8 is provided with two continuous print step surfaces, the outside of described seal ring 7 upper end is provided with the projection matched with above-mentioned two continuous print step surfaces, described step 1 upper-end surface is provided with groove 31, under described seal ring, 7 ends are provided with the triangular hill with above-mentioned fit depressions, curve bath 71 is provided with inside described seal ring 7, outside described seal ring 7, lower end is provided with the chamfering of 45 °.
Described seal ring 7 adopts urethane rubber material.Described seal ring protective sleeve 8 adopts iron material matter to make.
Described seal ring protective sleeve 8 is withheld on step 1 and step 24 by eight equal parts mould, and withholds into step two 0.5mm.
The advantage that embodiment described in the utility model has is: owing to being provided with seal ring protective sleeve, and the continuous step surface of seal ring protective sleeve lower end inside is sleeved on the continuous step surface of seal ring upper end, the triangular hill of seal ring lower end is installed in the groove of step one upper-end surface, therefore seal ring is not easy to be washed out by fluid, improves the reliability of rapid pipe joint work; Described seal ring is urethane rubber, improve the wear resistance of seal ring, resistance to pressure and elasticity, distortion when space between the triangular hill of the curve bath inside seal ring and the space of groove and seal ring lower end and the groove of step one works to seal ring provides space, easily shape is recovered, therefore good sealing effect after making sealed ring deformation.
The above; be only embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the utility model; the change can expected without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
