Detailed description of the invention
With reference to Fig. 1, Fig. 2, the present invention, specifically for flat gate valve, illustrates point structure of moderate testing tool 200 and a using method.
Flat gate valve comprises valve body 100, arrange in valve body 100 in valve body 100 and be provided with metering orifice 101, and flashboard installing hole 102 vertically disposed with metering orifice 101, be configured with the valve seat installing hole 103 coaxial with metering orifice 101 at flashboard installing hole 102 and the crossover location of metering orifice 101.When processing valve body 100, according to valve body 100 processing process, first metering orifice 101 and valve body 100 liang of end flanges of valve body 100 are processed, then the flashboard installing hole 102 of valve body 100 is processed, flashboard installing hole 102 process qualified after, again clamping flange, then through the metering orifice 101 of one end, processing is positioned at the valve seat installing hole 103 at middle part.
With reference to Fig. 3-6, of the present invention point of moderate testing tool 200, comprise pedestal 220, dial gauge 260 and indicator bracket 240, dial gauge 260 is fixedly connected on pedestal 220 by indicator bracket 240, pedestal 220 is provided with a datum level 221, the measuring stick portion 262 of described dial gauge 260 is positioned at pedestal 220 side at datum level 221 edge, and measuring stick portion 262 is vertical with datum level 221 arranges, described pedestal 220 is fixedly connected with by connecting rod 250 with indicator bracket 240, connecting rod 250 between pedestal 220 and indicator bracket 240 is also arranged with the measurement head 261 and the regulating block 230 of the distance of pedestal 220 that regulate dial gauge 260.Connecting rod 250 is screw rod, and pedestal 220, regulating block 230 are threaded by screw rod successively with indicator bracket 240, and cover has nut pedestal 220, regulating block 230 compressed with indicator bracket 240 on screw rod.
With reference to Fig. 7, the axial length dimension of valve seat installing hole 103 requires as 136.9mm, when processing valve seat installing hole 103, first carry out preliminary working, retain the allowance of 2mm, then by a point moderate testing tool 200, the detection of point moderate L cannot directly be measured, then needing to convert to by detecting the side-play amount of valve seat installing hole 103 both sides end face respectively and between this side flashboard installing hole 102 inwall, by comparing the size of both sides side-play amount, deciding which end to carry out fine finishining to.During detection, fitted in datum level 221 and valve seat installing hole 103 1 side end face of the pedestal 220 of point moderate testing tool 200, the measurement head 261 of dial gauge 260 is fitted with the inwall of flashboard installing hole 102, reads the reading of dial gauge 260, is recorded as m.If when the measurement head 261 of dial gauge 260 cannot touch the inwall of flashboard installing hole 102, at this moment need to change the less regulating block 230 of thickness, make dial gauge 260 measurement head 261 can with the contact internal walls of flashboard installing hole 102, simultaneously, reading can not exceed again the range of dial gauge 260, if time distant, then need to change the larger regulating block 230 of thickness, measuring distance is in the measurement category of dial gauge 260.When measuring after on the left of valve seat installing hole 103, then in the same way, a point moderate testing tool 200 is moved to opposite side and measures, and is n by the read-record of dial gauge 260.The size of comparative reading m and n, if m is greater than n, then illustrates that flashboard installing hole 102 is turned left side skew, when carrying out fine finishining, then directly processing its right end face, valve seat installing hole 103 being accomplished symmetrical as far as possible; If reading m is less than n, then illustrates that flashboard installing hole 102 is turned right skew, when carrying out fine finishining, then directly process left end face, thus guarantee valve seat installing hole 103 is symmetrical.
For the flat gate valve that aperture is less, divide the operating space of moderate testing tool 200 limited, therefore in order to improve a point operability for moderate testing tool 200, of the present invention point of moderate testing tool 200 also comprises pull bar 210, pull bar 210 comprises vertical pole portion 211 and is vertically installed in the cross bar portion 212 of one end, vertical pole portion 211, and forming cross section is the structure of T-shaped; Described pedestal 220 is provided with the perforated portion 223 that can pass cross bar portion 212, and the pedestal 220 being positioned at datum level 221 opposite side is provided with the concave part 222 that can hold cross bar portion 212, and concave part 222 and perforated portion 223 cross-over configuration.When measuring, first a point moderate testing tool 200 for removing pull bar 210 part is put into valve seat installing hole 103 from flashboard installing hole 102, then pull bar 210 is sent into from the metering orifice 101 of valve body 100 side, make the perforated portion 223 of cross bar portion 212 through pedestal 220 of pull bar 210, then rotating rod 210, cross bar portion 212 is made to fall into the concave part 222 of pedestal 220, then by tensile ties 210, make the datum level 221 of pedestal 220 and fit with valve seat installing hole 103 1 side end face, the measurement head 261 of dial gauge 260 is fitted with the inwall of flashboard installing hole 102, read the reading of dial gauge 260, complete surveying work.Like this, in the valve body 100 that space is less, immediately also can complete the detection to point moderate.
What be more prone to make the cross bar portion 212 of pull bar 210 falls into concave part 222, concave part 222 is vertical with perforated portion 223 to be arranged, during such rotating rod 21090 °, and tensile ties 210, namely the cross bar portion 212 of pull bar 210 falls into concave part 222, more convenient to operate.
The datum level 221 of pedestal 220 of the present invention is rounded face, and the cross section of pedestal 220 is circular, and the pedestal 220 of pedestal 220 is more easily fitted with the end face of valve seat installing hole 103.。
Dial gauge 260 of the present invention replaces with amesdial, can reach same testing goal, reaches same technique effect.
