Description
Technical field
The utility model relates to a kind of valve leakage inspector and detection method thereof.
Background technology
Valve needs factory testing, wherein, whether valve closing is well for one of topmost index, owing to valve pocket inner structure is complicated, location comparison is hidden, and the reason that occur leaking be likely to be import valve seat, sealing ring etc. and go wrong, when slightly leaking occurs in valve closing, leaking in valve pocket is not easy discovery.
Utility model content
The utility model, according to above not enough, provides a kind of valve leakage inspector, from the delivery port input water under high pressure of valve body, i.e. by reversely increasing setting-out, leak water detdction probe is arranged on the intersection of import valve seat and flap, thus facilitates detection to leak state.
The technical solution of the utility model is:
A kind of valve leakage inspector, comprising:
Valve body, valve body is provided with water inlet, delivery port；
Import valve seat, is arranged on the water inlet near valve pocket for the valve body；
Flap, can turn off or on import valve seat；
The drive mechanism of flap, controls flap action；
It is characterized in that, also include:
Leak water detdction is popped one's head in, rounded shape, flexible, and has openend, is arranged on the intersection of import valve seat and flap, and leak water detdction is popped one's head in and is provided with two output lines, can gather water leakage；
Detection controller, connects the output line of leak water detdction probe, and detection controller can export state of leaking.
Obviously, leak water detdction probe is arranged on water inlet ratio and is arranged on convenience in valve pocket, but Detection results is identical.
The circular shape of leak water detdction probe designs, flexible, have the main purpose of openend to have two, first, toroidal can coincide with the shape of import valve seat and the intersection of flap, accurate acquisition water leakage；Second, it is designed to elasticity, openend is convenient to insert from valve inleting water mouth.
It should be noted that the flap of different model, its drive mechanism is also different.
If be detected that leak, then whether the sealing ring first got rid of on flap is problematic, reexamines whether import valve seat leaks.
Described leak water detdction probe includes:
Two quoits, flexible and have openend, two quoits are cased with multiple insulating sleeve and mutual dislocation respectively, two output lines are connected with two quoits respectively；Quoit may select stainless steel, phosphor-bronze wire etc..
Can not gather after flowing to prevent from leaking, wrappage, can absorb water, in high-impedance state before water suction, in order to prevent quoit and valve body short circuit, have influence on test effect, wrappage is enclosed within outside two quoits.
As one of mounting means, the diameter of described two quoits is identical, be arranged in parallel.
As the two of mounting means, the diameter of described two quoits differs, in being generally aligned in the same plane.
As preferably, described wrappage is paper or cloth.
After preventing insulating sleeve from moving, causing short circuit, affecting Detection results, described insulating sleeve is heat-shrink tube.
As preferably, described detection controller is universal meter, and the resistance grade of universal meter can detect state of leaking.
The invention also discloses a kind of valve leakage detection method, including described a kind of valve leakage inspector, it is characterized in that, as follows:
A. valve is arranged on closed mode, described valve leakage inspector is installed；
B. the installing port of closed valve；
C. from the delivery port input water of valve body, high pressure conditions is kept；
If D. detection controller is without exporting state of leaking, then valve closing is good, discharges water under high pressure, takes out leak water detdction and pops one's head in, otherwise,
E. discharging water under high pressure, taking out leak water detdction probe, visually observe the leakage area of leak water detdction probe, correspondence finds out valve body or the region of interest of valve gap implements maintenance.
The utility model have simple in construction, low cost, convenient test fast accurately, significantly improve the beneficial effect of detection efficiency.
