Abstract
The utility model relates to a damping device for a pressure instrument, comprising a barrel with upper and lower openings, an upper connector, a lower connector and a transmission tube, wherein the upper connector and the lower connector are respectively connected at the two ends of the barrel and lead a sealing cavity to be formed in the barrel; the transmission tube is arranged in the sealing cavity of the barrel; the upper connector and the lower connector are provided with through holes; the two ends of the transmission tube are respectively connected with the through holes of the upper connector and the lower connector by threads; the transmission tube is spirally arranged in the barrel; and a damping sheath is arranged between the transmission tube and the inner wall of the barrel. The damping device for the pressure instrument is installed on an outlet pipeline of a pump, thereby preventing the pressure instrument from being directly installed on the pipeline in which medium flows, and reducing the damage to the pressure instrument due to the vibration of a pump body in the flowing process of the medium; the medium enters the spiral transmission tube through the hole of the upper connector, thereby reducing the damage to the pressure gage due to the vibration of the pump body; and simultaneously, the damping sheath is arranged between the transmission tube and the inner wall of the barrel, thereby playing a damping role for the transmission tube.
Description
Technical field
The utility model relates to a kind of instrument and meter service equipment, is specifically related to a kind of shock attenuation device of manometer.
Background technology
At present, tensimeter is applied to all trades and professions every field, the employed tensimeter of terminal pump house, because the infringement of the vibrations his-and-hers watches of pump greatly, a lot of tables are only with some months even just caused the inaccurate or damage of table in several days, bring great inconvenience to production, often changing tensimeter has also increased production cost.
Summary of the invention
At the problems referred to above, the purpose of this utility model provides a kind of shock attenuation device of manometer, and its good damping effect can be protected tensimeter effectively, increases work efficiency, and reduces production costs.
The technical scheme that realizes the utility model purpose is as follows:
A kind of shock attenuation device of manometer, the cylindrical shell that comprises upper and lower opening, be connected to the cylindrical shell two ends and inner barrel is formed the last connector of sealed cavity, following connector, and be arranged on transfer tube in the cylindrical shell sealed cavity, offer through hole on last connector, the following connector, the two ends of transfer tube are connected with the through hole whorl of last connector, following connector respectively, and being arranged in the cylindrical shell of described transfer tube spiral is provided with shock-absorbing sleeve between the inwall of transfer tube and cylindrical shell.
Described shock-absorbing sleeve is a rubber sleeve, and shock-absorbing sleeve can slow down the vibration of exterior vibration to transfer tube.
Described cylindrical shell is a metal cylinder, and metal cylinder is not yielding, and the transfer tube of its inside is played further protective effect.
Described upward connector, following connector adopt thread connecting mode to be connected with cylindrical shell, conveniently shock attenuation device are carried out installation and removal and safeguard.
Adopt such scheme, the shock attenuation device of manometer is installed on the delivery side of pump pipeline, avoids tensimeter to be directly installed on the pipeline of media flow, reduced since the vibrations of media flow process middle pump body to manometric damage.Medium enters in the spiral transfer tube by last connector through hole, has reduced pump housing vibrations to manometric damage, and the shock-absorbing sleeve between the inwall of transfer tube and cylindrical shell plays the effect of damping to transfer tube simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure, 1 is cylindrical shell, and 2 is last connector, and 3 are following connector, and 4 is transfer tube, and 5 is shock-absorbing sleeve.
Embodiment
Below in conjunction with the drawings and the specific embodiments the utility model is further described.
As shown in Figure 1, a kind of shock attenuation device of manometer, the cylindrical shell 1 that comprises upper and lower opening, be threaded in the cylindrical shell two ends respectively and inner barrel formed the last connector 2 of sealed cavity, following connector 3, and be arranged on spiral transfer tube 4 in the cylindrical shell sealed cavity, the spiral transfer tube is arranged in the cylindrical shell longitudinally, last connector, offer through hole on the following connector, the two ends of transfer tube respectively with last connector, the through hole whorl of following connector connects, be provided with shock-absorbing sleeve 5 between the inwall of transfer tube and cylindrical shell, shock-absorbing sleeve is enclosed within the outside of spiral transfer tube tightly, the assurance shock-absorbing sleeve is given full play to the cushioning effect of spiral transfer tube, shock-absorbing sleeve is a rubber sleeve, and cylindrical shell is a metal cylinder.
