Abstract
The utility model relates to a diaphragm-type pressure gauge diaphragm and a shell structure component which are in diaphragm welding fixing and is not easy to drop off. The utility model comprises a shell and a diaphragm; the shell is composed of a connecting block 1 having an axial through hole and a shell sleeve 1; the peripheral wall of one end of the connecting block 4 is fixedly connected with the diaphragm2; the peripheral wall of the diaphragm 2 is fixedly connected with the shell sleeve 1; a chamfer angle is arranged on the outside of the matching position between the connecting block and the shell sleeve to form a chamfer angle ring; the inner of the chamfer angle ring is provided with a welding ring so as to make the connecting block, the diaphragm and the shell sleeve be connected together fixedly. The utility model is applicable for producing diaphragm-type pressure gauge for measuring.
Description
The utility model belongs to tensimeter, particularly membrane pressure gage.
Membrane pressure gage in the prior art, watchcase are an integral structure component, in the watchcase internal fixation one diaphragm are arranged, and its fixed form is: fixing through the weldering knot with the watchcase inwall around the diaphragm.The defective of this table is: fixedly difficulty is big for diaphragm weldering knot, and diaphragm comes off easily.When particularly adopting stainless steel component, its weldering knot has more difficulty, and diaphragm is also easier to come off.
The purpose of this utility model is to provide a kind of diaphragm weldering knot easily fixing and do not allow caducous membrane pressure gage diaphragm and shell structure assembly for overcoming above-mentioned defective.
Technical solution of the present utility model is to comprise housing and diaphragm, its special character is that described housing is made up of the joint seat of offering axially extending bore and valve jacket, joint seat one end periphery wall ring set is consolidated with described diaphragm, and diaphragm periphery wall ring set is consolidated with described valve jacket.
Perisporium triplicity place sealed knot has the weldering ring formation within described joint seat one end periphery wall, diaphragm periphery wall and valve jacket one end.
The utility model is that the housing branch that will use membrane pressure gage always is set as joint seat and valve jacket, and diaphragm is intercalated in its perisporium in the annular gap of joint seat and valve jacket cooperation place, and is by weldering knot mode that joint seat, diaphragm and valve jacket three is solid welded together again.The gap of joint seat and valve jacket cooperation place is unsuitable wide, and being advisable by intercalation diaphragm perisporium, side is all established chamfering and formed the chamfering circle outside joint seat and the valve jacket cooperation place, and the weldering knot is implemented joint seat, diaphragm and valve jacket three are consolidated on the chamfering circle.
The utility model is owing to be set as joint seat and valve jacket with the housing branch, diaphragm is placed in joint seat one end periphery wall, valve jacket is placed in the diaphragm periphery wall, the three is solid welded together, overcome diaphragm thus and tied wall within the monolithic devices housing with its all side weld, the weldering knot defective that difficulty is big, diaphragm comes off easily makes the easy and diaphragm difficult drop-off of the utility model diaphragm weldering knot.
Below in conjunction with description of drawings embodiment of the present utility model.
Fig. 1 is the utility model structural representation;
Fig. 2 is Fig. 1 construction package partial enlarged drawing.
Membrane pressure gage diaphragm and shell structure assembly, comprise housing and diaphragm, described housing is made up of the joint seat 4 of offering axially extending bore and valve jacket 1, and joint seat 4 one end periphery wall ring sets are consolidated with described diaphragm 2, and diaphragm 2 periphery wall ring sets are consolidated with described valve jacket 1.Side is equipped with chamfering and forms filler ring outside joint seat 4 and valve jacket 1 cooperation place, and sealed knot has weldering ring formation 3 that joint seat 4, diaphragm 2 and valve jacket 1 three are consolidated in this filler ring.
Claims (2)
1, membrane pressure gage diaphragm and shell structure assembly, comprise housing and diaphragm, it is characterized in that described housing is made up of the joint seat of offering axially extending bore (4) and valve jacket (1), joint seat (4) one end periphery wall ring sets are consolidated with described diaphragm (2), and diaphragm (2) periphery wall ring set is consolidated with described valve jacket (1).
2, diaphragm as claimed in claim 1 and shell structure assembly is characterized in that perisporium triplicity place sealed knot has weldering ring formation (3) within described joint seat (4) one end periphery walls, diaphragm periphery wall and valve jacket (1) one end.
