Detailed description of the invention
With specific embodiment, the present invention is described in further detail below in conjunction with the accompanying drawings, but not as a limitation of the invention.
As it is shown in figure 1, the water pressure test of the present invention seals means of deflation, for the water pressure test of parts, described parts can be such as the end cap of flame-proof type explosion-proof motor, it is also possible to the equipment needing the water pressure test for other or parts.The present embodiment illustrates as a example by the end cap 5 of flame-proof type explosion-proof motor, and referring specifically to Fig. 2, end cap 5 has first end 1 and the second end 2, and first end 1 has the first port 3, and the second end 2 has the second port 4.
Continuing with Fig. 1, the water pressure test of the present invention seals means of deflation and includes fixed plate 6 and have the water channel cylinder 7 of endoporus 9, fixed plate 6 has through hole 8 (seeing Fig. 5), it is outer and fixing with water channel cylinder 7 that fixed plate 6 is set in water channel cylinder 7 by through hole 8, and in the present embodiment, fixed plate 6 utilizes the mode welded to be fixed together (seeing Fig. 3) with water channel cylinder 7.The wherein one side of fixed plate 6 is affixed with the end face of the first end 1 of end cap 5 and merges sealing.One end of the endoporus 9 of water channel cylinder 7 connects with the first port 3, and the other end blocks.I.e. endoporus 9 is a blind hole, and the outer wall of water channel cylinder 7 offers the radial hole 10 connected with endoporus 9, and radial hole 10 is provided with plugging part.The two ends of water channel cylinder 7 can all protrude from the two sides of fixed plate 6, it is also possible to wherein one end is concordant with the wherein one side of fixed plate 6, and the present embodiment is illustrated that one end of water channel cylinder 7 is concordant with the wherein one side of fixed plate 6.If the two ends of water channel cylinder 7 all protrude from fixed plate 6, then, when fixed plate 6 fits with first end 1, water channel cylinder 7 extend in the first port 3.
As a preferred embodiment of the present invention, as depicted in figs. 1 and 2, plugging part includes the pipeline 11 being connected on radial hole 10 and the control valve being arranged on pipeline 11.Control valve in the present embodiment uses water gas valve 12.In order to make, pipeline 11 and radial hole 10 are convenient to be connected, in the present embodiment, radial hole 10 is screwed hole, one end of pipeline 11 is provided with the external screw thread 14 being connected with screwed hole, the other end is provided with female thread 15 (seeing Fig. 4), water gas valve 12 is threadedly connected to the other end of pipeline 11, referring specifically to Fig. 1 and Fig. 2.
As shown in Fig. 4 and Fig. 1 and Fig. 2, the internal diameter of pipeline 11 is less than 1/3rd of its external diameter, and namely the internal diameter of pipeline 11 is less.It addition, the aperture of the endoporus 9 of water channel cylinder 7 is less than 1/3rd of the external diameter of water channel cylinder 7.And the internal diameter of pipeline 11 should be less than the aperture of endoporus 9.With the discharge of air in beneficially end cap 5, and it is easily controlled current.
During as the water pressure test, first fixed plate 6 is fitted tightly on the end face of first end 1 and with first end 1 fixing seal.End cap 5 is placed on hydraulic equipment platform, makes the second port 4 of end cap 5 be close to hydraulic equipment platform, and on end cap 5, put hold down gag, compress end cap 5 and make the second port 4 seal with hydraulic equipment platform.Water filling in end cap 5, open water gas valve 12 simultaneously, when water gas valve 12 there are flowing out, it is momentarily turned off water gas valve 12, continue water filling, when water injection pressure reaches setup pressure value, hydraulic equipment, automatically into packing state, is observed Pressure gauge upward pressure value and is in steady statue and keeps 12 seconds being eligible state.If force value decline, then observe end cap whether there is seepy question, if assemble cause leak, need re-assembly after again test, if the problem of end cap own cause leak then represent end cap defective.
The water pressure test using the present invention seals means of deflation, can end cover, the air that end cap inner product is stayed can be released again completely, in process of the test, ensure that pressure stability, can intuitively reflect the defect of the equipment such as end cap or part, it is possible to ensure end cap quality very well, and simple to operation during the water pressure test.
In order to make the sealing effectiveness between the first end 1 of fixed plate 6 and end cap 5 more preferable, another kind of preferred version as the present invention, continuing with Fig. 1, it is provided with sealing plate 13 between the first end 1 of fixed plate 6 and end cap 5, offering the through hole 16 for making the endoporus 9 of water channel cylinder 7 connect with the first port 3 on sealing plate 13, the sealing plate 13 in the present embodiment is offset plate.
The present embodiment is achieved a fixed connection by bolt 17 between fixed plate 6, sealing plate 13 and first end 1.The shape of fixed plate 6 and sealing plate 13 does not limits, as long as sealing the first port 3 and the endoporus 9 of water channel cylinder 7 can being made to connect with the first port 3.Due to the first port 3 generally circular in shape of end cap 5, fixed plate 6 and sealing plate 13 in the present embodiment all use annular plate, and through hole 8 and through hole 16 are circular hole.Owing to the bore of the first port of different parts exists difference in size, in order to make fixed plate 6 and sealing plate 13 convenient from the first end 1 of first port 3 with different bore to connect, as shown in Figure 5, offering corresponding multi-turn the second screwed hole 19 in fixed plate 6 and sealing plate 13, the center of circle of the second screwed hole 19 place circle in fixed plate 6 is respectively positioned on the axis of through hole 8 of fixed plate 6.The fixed plate 6 of the present embodiment is provided with four circle the second screwed holes 19, and wherein the second screwed hole 19 of outmost turns is four, and other three circles are three the second screwed holes 19, and from inner ring to outer ring, the aperture of the second screwed hole 19 is gradually increased.Four circle the second screwed holes 19 it also are provided with on sealing plate 13 in the present embodiment, the center of circle of the circle that the second screwed hole 19 on sealing plate 13 is surrounded is respectively positioned on the axis of through hole 16 of sealing plate 13, when fixed plate 6 and sealing plate 13 are assemblied on the end cap 5 of flame-proof type explosion-proof motor, the center of circle of the circle that the second screwed hole 19 on sealing plate 13 is surrounded is also on the axis of the through hole 8 of fixed plate 6.First end 1 is provided with circle first screwed hole 18, and when the bore of the first port 3 is bigger, fixed plate 6 is relative with the first screwed hole 18 with the second screwed hole 19 of the outer ring of sealing plate 13 and wears bolt 17 and realizes fixing；When the bore of the first port 3 is less, fixed plate 6 is relative with the first screwed hole 18 with the second screwed hole 19 of the inner ring of sealing plate 13 and wears bolt 17 and realizes fixing.I.e. for the first port 3 that bore is different, the fixing of fixed plate 6, sealing plate 13 and first end 1 will be realized by different the second screwed hole 19 is corresponding with the first screwed hole 18.
As shown in Figure 1 to Figure 3, the profile of water channel cylinder 7 is cylindric, and the cross section of the first port 3 is circular, and the bore of the first port 3 is more than the aperture of through hole 16, and the aperture of through hole 16 is more than the external diameter of water channel cylinder 7.
Above example is only the exemplary embodiment of the present invention, is not used in the restriction present invention, and protection scope of the present invention is defined by the claims.The present invention can be made various amendment or equivalent in the essence of the present invention and protection domain by those skilled in the art, and this amendment or equivalent also should be regarded as being within the scope of the present invention.
