Detailed Description

Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by those of ordinary skill in the art to which the invention belongs. The use of "first," "second," and similar terms in the description herein do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.

To maintain the following description of the embodiments of the present invention clear and concise, detailed descriptions of well-known functions and components may be omitted.

As shown in fig. 1, a valve pressure test table comprises a water tank 1, a lifting assembly arranged in the water tank 1 and a clamping assembly arranged on the lifting assembly, wherein the lifting assembly comprises a bracket 2, a first traction plate 3, a second traction plate 4 and a lifting cylinder 5; the four lifting cylinders 5 are symmetrically distributed in pairs and are fixed at the bottom of the inner part of the water tank 1, the telescopic ends of the four lifting cylinders 5 are vertically and upwards arranged, the second traction plate 4 is fixed at the telescopic ends of the two lifting cylinders 5 at the left side, and the first traction plate 3 is fixed at the telescopic ends of the two lifting cylinders 5 at the right side; the bracket 2 is fixed between the first traction plate 3 and the second traction plate 4, and the clamping assembly is arranged on the bracket 2.

The clamping assembly comprises an end seat 6, a pressing seat 7, a clamping cylinder 8 and a pressurizing cylinder 9; end seat 6 is fixed inside the right-hand member of bracket 2, and pressurized cylinder 9 is fixed in the left end outside of bracket 2, and it is inboard that bracket 2's left end is located to die clamping cylinder 8, and pressurized cylinder 9's flexible end transversely passes bracket 2's left end right and fixes on die clamping cylinder 8's fixed end, and die clamping cylinder 8's flexible end transversely sets up right, presses seat 7 to fix on die clamping cylinder 8's flexible end and mutually supports with end seat 6.

When the device is used, the water tank 1 is filled with clean water, the valve 10 to be tested is placed between the end seat 6 and the pressure seat 7, the telescopic end of the pressurizing cylinder 9 is driven to extend outwards, the clamping cylinder 8 and the pressure seat 7 are driven to move rightwards, the telescopic end of the clamping cylinder 8 is driven to extend outwards, and the valve 10 to be tested is clamped and fixed between the end seat 6 and the pressure seat 7 by means of the pressure seat 7; the telescopic ends of the four lifting cylinders 5 are driven to contract inwards at the same time, and then the bracket 2 is driven to descend by means of the first traction plate 3 and the second traction plate 4, so that the valve 10 to be tested is completely immersed into water by means of the clamping assembly.

Then, injecting clean and pure nitrogen into the valve 10 to be tested, pressurizing to a specified standard test pressure, keeping for a certain time, and observing whether bubbles overflow from pressure-resistant parts such as the valve body, the valve cover and the like and the sealing part between the valve body and the valve cover; if the bubble overflow phenomenon exists, the detected valve has a leakage point and is unqualified, and rework is needed again; and if no bubble overflows, the tested valve pressure is qualified.

The utility model adopts the mode of completely immersing the valve 10 to be tested in water to detect whether the valve 10 to be tested has leakage, and the test process is automatically completed without the help of manpower, thereby improving the working efficiency, simplifying the operation and saving time and labor; even a tiny leakage point can be found, and the test accuracy is further improved to avoid the occurrence of the missing detection phenomenon.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that various changes in the embodiments and modifications thereof may be made, and equivalents may be substituted for elements thereof; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
