Abstract
The invention discloses a four-way valve verticality detection tool and belongs to the technical field of detection tools. The four-way valve verticality detection tool comprises a dial indicator and a testing head connected with the dial indicator, a positioning sleeve is arranged at a position where an extensible rod of the dial indicator is connected with the testing head in a manner of being longitudinally slidable, and a screw for locking the positioning sleeve is arranged on the same. The testing head can be inserted into a bushing of a small valve body to detect verticality and depth after the small valve body and the bushing are assembled, the positioning sleeve is mounted through the screw, and position of the positioning sleeve is adjusted by tightening or loosening the screw so as to adjust inserting depth of the testing head to simply and accurately complete operation.
Description
Technical field
The present invention relates to a kind of four-way valve detection tool for detecting verticality, belong to testing tool technical field.
Background technology
Four-way change-over valve (hereinafter referred to as four-way valve) is a vitals in air-conditioning system, little valve body sleeve pipe assembly quality directly affects the quality of four-way valve, therefore, verticality after little valve body and sleeve pipe assemble and the degree of depth have higher technological requirement, but still do not have detection method very accurately in current industry.
Summary of the invention
For solving the problem, the invention provides a kind of structure simple, easy to operate, detect accurate four-way valve detection tool for detecting verticality.
The technical scheme that the present invention adopts for its problem of solution is:
A kind of four-way valve detection tool for detecting verticality, the measuring head comprise dial gauge, being connected with described dial gauge, described dial gauge is provided with expansion link, and the junction of expansion link and measuring head can slide up and down and is provided with locating sleeve, described locating sleeve is provided with the screw locking described locating sleeve.
Preferably, described measuring head adopts with described dial gauge and is threaded.
Preferably, the test lead of described measuring head is arranged to arc-shaped.
The invention has the beneficial effects as follows: measuring head can insert in little valve body sleeve pipe, detect little valve body and sleeve pipe assemble after verticality and the degree of depth, locating sleeve is installed by screw, by tightening or unscrewing screw, regulate the position of locating sleeve, and then regulate the insertion depth of measuring head, complete operation simply accurately.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is structural representation of the present invention.
In figure: 1, dial gauge; 2, locating sleeve; 3, screw; 4, measuring head.
Embodiment
A kind of four-way valve detection tool for detecting verticality as shown in Figure 1, the measuring head 4 comprise dial gauge 1, being connected with described dial gauge 1, the expansion link of described dial gauge 1, can slide up and down with the junction of measuring head 4 and be provided with locating sleeve 2, described locating sleeve 2 is provided with the screw 3 locking described locating sleeve 2.Measuring head 4 can insert in little valve body sleeve pipe, detect little valve body and sleeve pipe assemble after verticality and the degree of depth, locating sleeve 2 is installed by screw 3, by tightening or unscrewing screw 3, regulate the position of locating sleeve 2, and then regulate the insertion depth of measuring head 4, complete operation simply accurately.
Described measuring head 4 adopts with described dial gauge 1 and is threaded, and convenient installation with dial gauge 1 is fixed.
