Integrating instrument is generally adopted by being threadedly coupled with the connection popped one's head in.Structure as shown in Figure 1, more than DN65 flow instruments Integrating instrument be threadedly coupled by the standby tight mother of gauge outfit with connecting filament, excessive cap upper end is threadedly coupled with connecting filament, excessive cap lower end With the threaded connection of probe；Structure as shown in Figure 2, integrating instrument and the screen bar threaded upper ends of the flow instrument of DN10-DN50 connect It connects, screen bar lower end compresses probe, and screen bar is threadedly coupled with probe socket.

Integrating instrument with probe and probe socket when parts when being connected, have particular requirement to each part position relation.Such as It is required that integrating instrument display surface is parallel with probe tip joint face, i.e., face 1 is parallel with face 3；The direction sign identified surface and product of probe socket Calculation instrument display surface is parallel, i.e., face 2 is parallel with face 1；The flange face of housing is vertical with integrating instrument display surface, i.e., face 4 is vertical with face 1. And for the convenience for repairing dismounting, sealing cannot be encrypted at screw thread.Therefore in the case where fluid sealant can not be installed additional, in order to protect Hold the flange face fixed position relative of integrating instrument display surface, the direction sign identified surface of probe socket, probe tip joint face or housing Relation, correlated parts screw thread where can frequently result in each face can not be tightened, loosened, and when assembling needs to adjust repeatedly, bothersome laborious.

The content of the invention

The utility model is exactly the direction sign mark in order to solve existing structure in adjustment integrating instrument display surface, probe socket During the flange face fixed position relative relation in face, probe tip joint face or housing, the problem of correlated parts is caused to loosen, proposes It is a kind of to keep display surface, identified surface, joint face or flange face position is fixed and correlated parts firmly install flow instrument.

The technical solution of the utility model is a kind of flow instrument, it is characterized in that：Equipped with integrating instrument, probe, probe socket, Fixed seat and hexagon socket head cap screw, it is described probe be equipped with clamp, it is described probe and the fixed seating in the integrating instrument with it is described Among probe socket, the fixed seat is anchored on by the hexagon socket head cap screw on the integrating instrument or the probe socket, by described in Clamp is pressed on the integrating instrument or the probe socket, and the probe socket is anchored on the fixed seat by the hexagon socket head cap screw Or on the integrating instrument.

Preferably, the fixed seat is equipped with the cavity being recessed inwardly or boss and coordinates with the clamp.

Preferably, the probe socket is pressed on the integrating instrument.

The utility model advantageous effect is to ensure integrating instrument display surface, the direction sign identified surface of probe socket, probe tip The part by one-step such as the flange face fixed position relative relation of joint face or housing, integrating instrument, probe socket and probe socket are installed to Position, and installation is firm, does not loosen.

Specific embodiment

The utility model is described further with reference to embodiment：

Embodiment 1：As shown in Fig. 3 to Fig. 4, more than DN65 flow instruments equipped with integrating instrument 101, small probe socket 204, are consolidated Reservation 202, long probe 206, M3 hexagon socket head cap screws 203 and M4 hexagon socket head cap screws 205.206 upper ends of long probe are equipped with clamp 201； 101 bottom of integrating instrument is set there are two threaded hole；The small probe socket 204 of hollow cylindrical is equipped with the sky being recessed inwardly in the axial direction Chamber and protrude outward boss, boss sets that there are two the through holes parallel with axis；The fixed seat 202 of hollow ring is set there are two spiral shell Pit and two through holes, fixed seat 202 is additionally provided with the cavity being recessed inwardly and the clamp 201 of 206 upper ends of long probe is adapted, energy 201 part of clamp is enough made to sink in 202 concave cavity of fixed seat.

In assembling, 202 cavity side of fixed seat is first inserted in 201 one end of clamp along long 206 probe sides of probe, then by small spy 204 cavity side of headstock is inserted in 201 one end of screen bar clamp along long 206 probe one end of probe.The position of the long probe 206 of adjustment, is protected It is parallel with integrating instrument display surface 1 to hold probe tip joint face 3, by two M3 hexagon socket head cap screws 203 through 202 through hole of fixed seat with The threaded hole of integrating instrument 101 is tightened, and ensures that clamp 201 is anchored on 101 bottom of integrating instrument, fixed seat 202 is sunk in 201 part of clamp In concave cavity；Small 204 position of probe socket is adjusted, keeps the direction sign identified surface 2 of probe socket and integrating instrument display surface 1 flat Row is tightened two M4 hexagon socket head cap screws 205 through small 204 through hole of probe socket and the threaded hole of fixed seat 202, small probe socket 204 compress integrating instrument 101, and fixed seat 202 can be sunk to screen bar clamp 201 in small 204 concave cavity of probe socket.
