Specific embodiment

In order to which the technical means, creative features, achievable purpose and effectiveness to the utility model are easy to understand, tie below Conjunction is specifically illustrating, and the utility model is further described.

As shown in Figure 1-3, ball electromagnetic relief valve special testing tool, including cylinder 1 and pass through first flange 2 and cylinder The water inlet pipe 3 that 1 bottom is connected, the inside of cylinder 1 are respectively equipped with valve seat 4 and spherical parts 5, and spherical parts 5 are placed on valve seat 4, The first pressing mechanism and the second pressing mechanism of pressing spherical parts 5 are respectively provided on the top of cylinder 1 and side wall, first presses Press mechanism includes briquetting 7 and the second flange 6 for being fixed on the top of cylinder 1, and second flange 6 is run through in the bottom of briquetting 7, and with Spherical parts 5 are in contact, and the top of second flange 6 is additionally provided with the first regulating mechanism for adjusting pressing mechanism, the second pressing machine Structure is located at the horizontal axis 8 of 1 side of cylinder, and the side of horizontal axis 8 is also in contact with spherical parts 5, and the one side wall of cylinder 1 is equipped with for adjusting Save the second regulating mechanism of the second pressing mechanism.

First regulating mechanism is the blind plate 9 that 6 top of second flange is arranged in, the bottom middle position of blind plate 9 and briquetting 7 Top be fixedly linked, fixed between 6 both ends of both ends and second flange of blind plate 9 by two 10 phases of stud, Mei Geshuan Hexagonal (hexagon)nut 11 is threaded at the both ends screw thread of hook bolt 10.

Second regulating mechanism is the axle sleeve 12 being fixed in 1 one side wall of cylinder, and one end of axle sleeve 12 is equipped with gland 13, horizontal axis 8 other side through cylinder 1 and with 12 screw thread of axle sleeve be socketed and fixed with 13 phase of gland, between gland 13 and axle sleeve 12 also by Two 10 phases of stud are fixed, and hexagonal (hexagon)nut 11, and axis are also threaded at the both ends screw thread of each stud 10 It is also arranged with stone mill packing washer 15 respectively between set 12 and horizontal axis 8.

One end of water inlet pipe 3 is communicated with water supply connector 14.

Stud 10 uses 8.8 grades of studs, and hexagonal (hexagon)nut 11 uses I type hexagonal (hexagon)nut.

The outside of cylinder 1 is additionally provided with flowmeter, and the both ends of flowmeter are each provided at the contact surface between spherical parts 5 and valve seat 4 On, it is therefore an objective to detect whether the water in water inlet pipe 13 enters in cylinder 1, may thereby determine that 5 first pressing mechanism of spherical parts and Second pressing mechanism presses pressure respectively, and the air-tightness between spherical parts 5 and valve seat 4 keeps good.

The upper surface of valve seat 4 is smooth, it is therefore an objective to guarantee that the lower surface of spherical parts 5 is all contacted with 4 upper surface of valve seat, thus It can accurately detect whether the air-tightness between spherical parts 5 and valve seat 4 keeps good.

Working principle:

1, spherical parts 5 are placed on valve seat 4 first, then by the bottom of the briquetting 7 in second flange 6 and horizontal axis 8 One end be in contact respectively with the top of spherical parts 5；

2, the horizontal axis 8 in the briquetting 7 and the second pressing mechanism on the first pressing mechanism is then utilized respectively respectively to ball The top and side of shape part 5 are pressed, and concrete operations are as follows:

2.1, the hexagonal (hexagon)nut 11 on each stud 10 of the first pressing mechanism is rotated, is made blind on the first pressing mechanism Plate 9, to drive the bottom of briquetting 7 mobile toward the direction of spherical parts 5, then makes to press toward close to the movement of the direction of cylinder 1 Block 7 presses spherical parts 5, makes to fit closely between spherical parts 5 and valve seat 4,

2.2, the hexagonal (hexagon)nut 11 on each stud 10 of the second pressing mechanism is rotated, to make on the second pressing mechanism Gland 13 towards axle sleeve 12 side it is mobile, then make horizontal axis 8 mobile towards the side of spherical parts 5, then make the one of horizontal axis 8 Side presses spherical parts 5；

3, water supply connector 14 is then utilized, then is gone at this time using flowmeter by water inlet pipe 13 toward the inside water flowing of cylinder 1 Whether the inside of test cylinder 1 there is water, proves that the air-tightness between spherical parts 5 and valve seat 4 is good if there is not water.

The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row The technical staff of industry it should be appreciated that the present utility model is not limited to the above embodiments, do not depart from the spirit of the present invention and Under the premise of range, the utility model also has various changes and improvements, these changes and improvements both fall within claimed Within the scope of utility model.The protection scope of the present invention is defined by the appended claims and their equivalents.
