Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the A-A cut-open view of main frame among Fig. 1.
Embodiment
The invention will be further described below in conjunction with drawings and Examples.
As Fig. 1, shown in 2, valve is tested streamline automatically, is made of the 1 vertical installation of valve Test Host, vertically placement valve Test Host 1, water tank 16, hydraulic fluid tank 21, test pump 22, control box 15 etc.One cover delivery track 6 is installed below the test platform of main frame 1, it is closed that delivery track is, vertical installation, the two ends circular arc connects transition, place several transport trolleys 5 in the delivery track 6, rolling wheel 13 is housed below the transport trolley 5, and transport trolley 5 is used to carry valve and valve is delivered to test platform.One end of delivery track 6 is equipped with transport trolley and spins upside down mechanism 24, transport trolley spins upside down mechanism 24 and is made up of upset fork 17, driving chain 19, motor reducer 18, when moving to the lower railway transport trolley, transport trolley 5 spins upside down mechanism 24 places, transport trolley spins upside down mechanism 24 and drives driving chain 19 at motor reducer 18, driving chain 19 drives upset fork 17, transport trolley 5 is turned through track circular arc junction, make transport trolley wheel 13 down in getting on the right track, be used for carrying again the valve of needs test.Valve test action process simulation screen, valve test pressure intensity display, PLC programming controller and relevant circuit and operating parts etc. are housed in control box 15.
As shown in Figure 3, valve Test Host 1 is by frame 23, clamping cylinder 2, clamping disk(-sc) 3, valve rod is opened rotating mechanism 11 and is formed, frame 23 is made of left frame 23a and right frame 23b, between left frame and the right frame is test platform, on a left side, in the right frame 23, on the test platform, transverse horizontal, two valve test position fix clamping disk(-sc)s 3 are installed face-to-face, clamping disk(-sc) 3 is provided with position sensor of valve 14, clamping cylinder 2 is equipped with in clamping disk(-sc) 3 back, be provided with below the clamping cylinder 2 and regulate hoist cylinder 4, when the big or small centre-height of valve changes, adjust the upper-lower position of clamping cylinder 2 and clamping disk(-sc) 3 by regulating hoist cylinder 4, make clamping disk(-sc) 3 can be in the center of valve flanges.Be provided with supporting upright post above the left frame 23a, column 7 is provided with feather key 12, mounting support plate 8 flexibly connects by guide pin bushing and column 7, between mounting support plate 8 and the left frame 23a top panel hoist cylinder 9 is housed, the piston rod of hoist cylinder 9 is fixedlyed connected with support plate 8, valve rod is housed above support plate 8 right-hand members opens rotating mechanism 11, be connected to valve opening extension bar 10 on the rotating mechanism output shaft.
