It is more than spacing section 6 of the radial direction of thread segment 7 with maximum gauge, and is radially at least partially disposed in via 8 for spacing section 6, to cut-off
The formation of valve 1 is radially spacing, can effectively improve radial positioning precision of the threaded connector 4 to shut-off valve 1, prevent 1 phase of shut-off valve
Radially deviated for valve rack 2 so that the installation accuracy of shut-off valve 1 can meet the positioning requirements of ratio-frequency welding.
Preferably, thread segment 7 is threadedly coupled and is fixed on valve rack 2, or, thread segment 7 includes self-tapping screw, valve
Connecting hole is provided with stent 2, thread segment 7 is tightened in connecting hole., can not when thread segment 7 is self-tapping screw
With thread mill drilling on valve rack 2 again, directly thread tapping is carried out using self-tapping screw and is tightened on valve rack 2,
The simpler convenience of connection structure, can reduce manufacturing procedure, reduce processing cost.
Preferably, radially it is entirely located in via 8 for spacing section 6, bolt head 5 is pressed in mounting base 3.In the present embodiment
In, pass through the footpath that is arranged in via not in contact with, shut-off valve 1 between the periphery of the thread segment 7 in via 8 and via 8
It is radially spacing to spacing section 6 progress, while axial limiting is carried out to shut-off valve 1 by bolt head 5, it is connected through a screw thread part 4
Bolt head 5 and radially spacing section 6 of mutual cooperation, realize the effective accurate of mounting structure to shut-off valve 1 on valve rack 2
Positioning so that the installation accuracy of shut-off valve 1 can meet the positioning accuracy request of ratio-frequency welding.
Preferably, radially spacing section 6 be cylindrical section or conical surface section, direction section face of the conical surface section along remote bolt head 5
Product is successively decreased.When radially spacing section 6 be cylindrical section when, can be by controlling the fit precision between cylindrical section and via 8 to ensure
The radially installed precision of shut-off valve 1, is more easily accurately positioned.Preferably, via 8 is unthreaded hole.
When radially spacing section 6 be the conical surface section when, conical surface section can be made to be integrally located in via 8, at this time the maximum of conical surface section
Diameter is less than the diameter of via 8, is merely able to form shut-off valve 1 radially spacing, it is necessary to by conical surface section and bolt head 5 match
Close, to realize the axially and radially locating on valve rack 2 of shut-off valve 1.Since the cross-sectional sizes of conical surface section are to gradually change
, therefore can make to form good radial fit between the maximum outside diameter of conical surface section and via 8, reduce radial fit gap.Together
When gradually changed due to the section of conical surface section, the machining accuracy of conical surface section can be reduced, it is only necessary to ensure conical surface section
Processing dimension at maximum outside diameter, without ensureing the processing dimension at conical surface section other positions, can reduce radially spacing
The difficulty of processing and processing cost of section 6, improve processing efficiency.In addition, conical surface section is passed along the direction section away from bolt head 5
Subtract, installation of the threaded connector 4 in via 8 can also be formed and be oriented to, it is more convenient radially to install into via for spacing section 6
In 8.
Preferably, the outer circumferential surface of conical surface section is convex globoidal, can increase the volume of conical surface section, and the structure for increasing conical surface section is strong
Degree, reduces the diameter of conical surface section in axial direction and reduces speed, more efficiently ensures conical surface section and the radial fit essence of via 8
Degree.
Preferably, radially spacing section 6 when be conical surface section, the maximum gauge of conical surface section is more than the diameter of via 8, threaded connection
Part 4 is pressed abd fixed in mounting base 3 by conical surface section.In the present embodiment, since the maximum gauge of conical surface section is more than via 8
Diameter, therefore position-limiting action power axially and radially at the same time can apply shut-off valve 1 by conical surface section, so as to more added with
Effect ground ensures the axially and radially fit precision between shut-off valve 1 and valve rack 2.Preferably, the lower face of bolt head 5 at this time
Fit clearance between the upper surface of mounting base 3 is less than 1mm and is more than 0.2mm, can to avoid bolt head 5 and mounting base 3 it
Between hypotelorism and the cooperation to radially spacing section 6 and via 8 causes to interfere, can also avoid between bolt head 5 and mounting base 3
Hypertelorism and cause 5 protrusion height of bolt head excessive, influence the setting etc. of other structures.
Preferably, conical surface section or the height of cylindrical section are 2.5 to 3.5mm, it is therefore preferable to 3mm, 7 length of thread segment for 12 to
14mm, it is therefore preferable to 13mm.Spacing section 6 of radial direction herein can also be other structures.
Preferably, the conical surface gradient of conical surface section is 83 to 87 degree, it is therefore preferable to 85 degree.
Preferably, it is radially spacing section 6 small with 8 clearance fit of via, the spacing section 6 unilateral gap between via 8 of radial direction
In 0.5mm, so as to ensure that radially spacing section 6 fit clearance between via 8 is less than 1mm so that shut-off valve 1 and valve
Radial fit gap between stent 2 is less than 1mm, meets the positioning accuracy request of ratio-frequency welding.
Above-mentioned threaded connector is, for example, screw.
In the present embodiment, shut-off valve 1 is connected by screw and valve rack 2, the mounting base 3 of original screw and shut-off valve 1
During assembling, shut-off valve 1 easily shifts in the radial direction of screw, causes shut-off valve 1 and valve rack 2 to position and be not allowed, with
Big valved tube that shut-off valve 1 connects, minor valve pipe can also produce the inaccurate phenomenon of corresponding positioning, minor valve pipe, big valved tube with
It can not be accurately positioned during corresponding connecting line welding, cause to weld uneven, it is impossible to carry out high-frequency welding, have impact on pipeline
Automatic welding.
When being assembled using the threaded connector 4 of the application with the mounting base 3 of shut-off valve 1, the root of threaded connector 4 can be suitable
Smooth assembles with mounting base 3, valve rack 2.Spacing section 6 of the radial direction of threaded connector 4 is the conical surface section during assembling, can play guiding
And positioning action, it can effectively prevent shut-off valve 1 from being moved along screw radial direction, make shut-off valve 1 and the positioning of valve rack 2 accurate
Really, the minor valve pipe that is connected with shut-off valve 1, big valved tube accurate positioning, corresponding connecting line and minor valve pipe, big valved tube
