Abstract
A manometer is suitable for indicating the pressure of any kinds of vessels storing pressure. The aim of the utility model is to overcome the shortcomings of the prior manometer that it is not convenient to get back to the work and the manometer elements will be destroyed. The manometer has a manometer body, a manometer cover and an adpressing ring.
Description
Technical field the utility model relates to a kind of tensimeter, is applicable to the pressure indication in the various pressure store containers.
The background technology tensimeter comprises table body, watch glasses.Be provided with pressure sensitive device and pressure-indication means in the table body, table body bottom has the people's of leading gases at high pressure or liquid center hole, and the duct connects the pressure sensitive device; Watch glasses uses transparent material, with the sealing of table body, so that pressure sensitive device and pressure-indication means in indication of observation pressure and the protection table body; Table body below has the table body and dwindles part, and this dwindles part and has the rib-loop that is connected with pressure vessel or pipeline.Make tensimeter at present, watch glasses has two kinds with the mode of table body sealing, and the one, watch glasses is embedded in vertical table body inwall, as Fig. 1; The 2nd, watch glasses is provided with shoulder, and watch glasses is blocked in the reducing of table body, as Fig. 2.Because defective in quality unavoidably in the tensimeter manufacture process, after detecting, take apart and do over again, for preceding a kind of sealing means, take apart bothersomely, and watch glasses must be scrapped; For a kind of sealing means in back, watch glasses, table body are all scrapped, and it is meaningless to do over again.This has just inevitably improved manufacturing cost.
Utility model content the purpose of this utility model is to provide a kind of watch glasses reliable with table body sealing, and take apart do over again convenient can't damage table body, the technical scheme of watch glasses.
Its technical scheme is that a kind of tensimeter comprises and shows body (1), watch glasses (2), is provided with pressure sensitive device and pressure-indication means in the table body (1), shows the body bottom and has the center pit that imports gases at high pressure or liquid, duct connection pressure sensitive device; Watch glasses (2) uses transparent material, be tightly connected with table body (1), table body (1) below has the table body and dwindles part, this dwindles part and has the rib-loop that is connected with pressure vessel or pipeline, it is characterized in that: described table body (1) is tightly connected with watch glasses (2), be to press circle (3), press circle (3) and press watch glasses (2) and block table body (1) at table body (1) and watch glasses (2) peripheral hardware one.
In order to increase the effect of sealing, can between table body (1) and watch glasses (2), establish an O-ring seal (4), press circle (3) and press watch glasses (2), O-ring seal (4) and block table body (1).
Adopt technique scheme, watch glasses is reliable with the sealing of table body, for defective in quality tensimeter, take apart do over again convenient can't damage table body, watch glasses, help significantly to reduce cost.
Description of drawings
Fig. 1 is the tensimeter cut-open view of prior art, and watch glasses is embedded in vertical table body inwall.
Fig. 2 is the tensimeter cut-open view of prior art, and watch glasses is blocked in the reducing of table body.
Fig. 3 is a tensimeter cut-open view of the present utility model.
Fig. 4 is the partial enlarged drawing of Fig. 3.
Embodiment
As Fig. 3, watch glasses (2) adopts the polycarbonate O-ring seal with the injection moulding process manufacturing, and the external diameter ratio of watch glasses (2) presses 0.45～0.5 millimeter of circle (3) internal diameter; Table body (1) is made plating nickel on surface with brass, and the internal diameter that the external diameter ratio of table body (1) presses circle (3) is big 0.1～0.2 millimeter; Length A-the B that presses the clinching portion (5) of circle (3) is 1 millimeter, presses circle (3) and makes with thin corrosion resistant plate punching press.O-ring seal (4) is made with rubber.During assembling, on table body (1), put O-ring seal (4), watch glasses (2) successively, press circle (3), to press circle (3) with pressing machine and depress, compress watch glasses (2), O-ring seal (4) and table body (1), and press circle (3) and tightly block and show body (1) and make it not unclamp.To press circle (3) with pressing machine deviates to show body (1) in the other direction when taking apart.
Claims (2)
1, a kind of tensimeter comprises table body (1), watch glasses (2), is provided with pressure sensitive device and pressure-indication means in the table body (1), and table body bottom has the center pit that imports gases at high pressure or liquid, and the duct connects the pressure sensitive device; Watch glasses (2) uses transparent material, be tightly connected with table body (1), table body (1) below has the table body and dwindles part, this dwindles part and has the rib-loop that is connected with pressure vessel or pipeline, it is characterized in that: described table body (1) is tightly connected with watch glasses (2), be to press circle (3), press circle (3) and press watch glasses (2) and block table body (1) at table body (1) and watch glasses (2) peripheral hardware one.
2, tensimeter according to claim 1 is characterized in that, establishes an O-ring seal (4) between table body (1) and watch glasses (2), presses circle (3) and presses watch glasses (2), O-ring seal (4) and block table body (1).
