Abstract
A valve leakage testing table mainly resolves problems that detection results of an existing valve leakage testing device are greatly affected by pressure of a pump outlet, and a pump with high rated pressure is high in cost. The valve leakage testing table is characterized in that a closed pressure storage tank (10) is fixed at the other end of an engine base (1), a static chuck (4) is fixed on the side wall of the pressure storage tank (10) via a fixing shaft (3), and a pump (2) is communicated with the pressure storage tank (10) via a liquid inlet pipe (11). The valve leakage testing table is improved on the basis of the prior art, and has the advantages of compact structure, low detection error and cost and high detection efficiency.
Description
Technical field
The utility model relates to a kind of valve detection device, especially valve leak amount test board.
Background technology
The valve leak amount is the important technology index of valve mass, in order to guarantee the effective control to valve mass, need detect the valve leak amount.Existing valve leak measurement trial assembly is put mainly and is made up of support, pump, stationary shaft, quiet chuck, moving chuck, movable axis, hydraulic cylinder and Hydraulic Station, be equipped with central through hole on stationary shaft, quiet chuck, moving chuck and the movable axis, pump communicates with stationary shaft and quiet chuck successively by feed tube, moving chuck communicates with movable axis and discharging tube successively, detects the leakage rate of valve under certain pressure by the input quantity of tracer liquid and the difference of discharge capacity.Because the liquid that enters in the valve is imported by pump, therefore pump performance is had relatively high expectations, the fluctuation of pump discharge pressure directly influences testing result, and it is big to detect error, and the pump of high rated pressure is relatively more expensive, the cost height.
The utility model content
Measure trial assembly and put testing result and be subjected to pump discharge pressure to influence big and select the high deficiency of pump cost of high rated pressure for use in order to overcome existing valve leak, the utility model provides a kind of valve leak amount test board, this valve leak amount test board pin improves on the basis of background technology, has compact conformation, little, the low high characteristics of detection efficiency that reach of cost of detection error.
The technical solution of the utility model is: this valve leak amount test board comprises support, pump, stationary shaft, quiet chuck, moving chuck, movable axis, hydraulic cylinder and Hydraulic Station, support is " U " shape, one end of support is equipped with hydraulic cylinder and Hydraulic Station, hydraulic cylinder links to each other with the movable axis that passes support, moving chuck is fixed on the end of movable axis, stationary shaft, quiet chuck, be equipped with central through hole on moving chuck and the movable axis, moving chuck communicates with movable axis and discharging tube successively, the other end of support is fixed with airtight accumulator, quiet chuck is fixed on the sidewall of accumulator by stationary shaft, and pump communicates with described accumulator by feed tube.
Be equipped with the cut-out ball valve on described feed tube and the discharging tube.
Described hydraulic cylinder fixes with support by the lengthening cover.
Between described quiet chuck and the tested valve, be equipped with the top cover between moving chuck and the tested valve, described top cover is variable-diameter structure, pushes up to put to be provided with central through hole.
The beneficial effects of the utility model are: owing to take such scheme, when detecting valve, liquid enters accumulator by pump, and then enter in the tested valve by the stationary shaft center pit of installing on the accumulator sidewall, make that the fluid pressure that enters in the tested valve is steady, not fluctuation, the detection error is little, because accumulator is arranged, adopts common pump just can reach the required pressure of test, reduced cost, accumulator be placed in support one end dexterously, also played supporting role, compact conformation simultaneously, volume is little, is convenient to move.
Description of drawings
Accompanying drawing 1 is a structure cut-open view of the present utility model.
Accompanying drawing 2 is structure cut-open views of top cover 15 in the utility model.
1-support among the figure, the 2-pump, the 3-stationary shaft, the quiet chuck of 4-, 5-moves chuck, the 6-movable axis, the 7-hydraulic cylinder, the 8-Hydraulic Station, the 9-discharging tube, the 10-accumulator, the 11-feed tube, 12-cuts off ball valve, the 13-cover that extends, the tested valve of 14-, 15-pushes up cover.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, this valve leak amount test board comprises support 1, pump 2, stationary shaft 3, quiet chuck 4, moving chuck 5, movable axis 6, hydraulic cylinder 7 and Hydraulic Station 8, support 1 is " U " shape, one end of support 1 is equipped with hydraulic cylinder 7 and Hydraulic Station 8, hydraulic cylinder 7 links to each other with the movable axis 6 that passes support 1, moving chuck 5 is fixed on the end of movable axis 6, stationary shaft 3, quiet chuck 4, be equipped with central through hole on moving chuck 5 and the movable axis 6, moving chuck 5 communicates with movable axis 6 and discharging tube 9 successively, the other end of support 1 is fixed with airtight accumulator 10, quiet chuck 4 is fixed on the sidewall of accumulator 10 by stationary shaft 3, and pump 2 communicates with described accumulator 10 by feed tube 11.When detecting valve, liquid enters accumulator 10 by pump 2, and then is entered in the tested valve 14 by stationary shaft 3 center pits of installing on accumulator 10 sidewalls, make that the fluid pressure that enters in the tested valve 14 is steady, not fluctuation, it is little to detect error, because accumulator 10 is arranged, adopt common pump 2 just can reach the required pressure of test, reduced cost, accumulator 10 is placed in an end of support 1 dexterously, also played simultaneously supporting role, compact conformation, volume is little, is convenient to move.
By shown in Figure 1, be equipped with on described feed tube 11 and the discharging tube 9 and cut off ball valve 12.Cut off ball valve 12 and be used for controlling opening and cutting off of feed tube 11 and discharging tube 9.
By shown in Figure 1, described hydraulic cylinder 7 fixes with support 1 by lengthening cover 13.Lengthening cover 13 plays the effect of protection and supporting cylinder 7, has also reduced the distance at support 1 two ends, makes support 1 compact conformation.
By shown in Figure 2, between described quiet chuck 4 and the tested valve 14, be equipped with top cover 15 between moving chuck 5 and the tested valve 14, described top cover 15 be a variable-diameter structure, pushes up to overlap 15 and be provided with central through hole.Auxiliary member when top cover 15 is tested valve 14 clampings, during actual production, can make suitable series of the present utility model top cover 15, usable range of the present utility model is increased by the tested valve 14 of different size, can detect the valve of plurality of specifications, the detection efficiency height.
