Abstract
The utility model discloses a novel flowmeter, which comprises a measured pipeline, a measuring tube and a ball valve, wherein a fixed nut is fixed on one side of the measured pipeline; a lower tightening piece is arranged in the fixed nut by a gasket; a fixed flange is arranged on the other side of the measured pipeline; the fixed flange is in bolt connection with the flange end surface on one side of the ball valve by a sealing gasket; the flange end surface on the other side of the ball valve is in bolt connection with one end of a packing flange by a sealing gasket; the other end of the packing flange is connected with a lifting plate; meanwhile, a packing press plate component is arranged between the end surface of the packing flange and the lifting plate; and the packing press plate component is fixed on the end surface of the packing flange. The novel flowmeter disclosed by the utility model has the benefits that the structure is simple, the production cost is low, and the maintenance is convenient and rapid because during maintenance, only the ball valve needs to be closed and the whole system does not need to be closed.
Description
Technical field
The utility model relates to flowmeter, particularly a kind of new flowmeter.
Background technology
Flowmeter on the existing market is in when maintenance, usually need to close whole system after, the overall pulling down flowmeter keeps in repair it again; Affect the whole system operation when wasting time and energy.
Summary of the invention
For the shortcoming of existing flowmeter, the utility model provides a kind of novel flowmeter.
To achieve these goals, the utility model institute Adopts measure
A kind of new flowmeter comprises tested pipeline, measuring tube, ball valve, and described tested pipeline one side is provided with hold-down nut, is provided with lower securing member by pad in the hold-down nut; The tested pipeline opposite side is provided with mounting flange; Mounting flange is connected with the end face of flange of ball valve one side by gasket seal and bolt connecting mode; The end face of flange of ball valve opposite side is connected with filler flange one end by gasket seal and bolt connecting mode; The filler flange other end is connected with boatswain chair, simultaneously, is provided with the hold-down grid assembly between filler flange end face and boatswain chair, and the hold-down grid assembly is fixed on the filler flange end face; The boatswain chair inner circle is fixedly installed measuring tube, measuring tube capping and the crimping of lower securing member internal chamber wall phase that measuring tube one end passes successively hold-down grid assembly, filler flange, ball valve, gasket seal, mounting flange, tested pipeline and arranges by this end face; The measuring tube other end passes boatswain chair and is connected with the valve head assembly, and valve head assembly end face center is provided with plug;
Being bolted mode between described boatswain chair and filler flange end face is flexibly connected;
Be provided with positive pressure guiding pipe, negative pressure guiding pipe in the described measuring tube, simultaneously, be movable connection method between measuring tube and hold-down grid assembly, filler flange, ball valve, gasket seal, mounting flange, tested pipeline, lower securing member.
The beneficial effects of the utility model: simple in structure, production cost is low; Whole system need be do not closed during maintenance, only ball valve need be closed, easy to maintenance quick.

Embodiment
A kind of new flowmeter as shown in Figure 1, comprises tested pipeline 1, measuring tube 10, ball valve 15, and described tested pipeline 1 one sides are provided with hold-down nut 12, is provided with lower securing member 13 by pad 14 in the hold-down nut 12; Tested pipeline 1 opposite side is provided with mounting flange 7; Mounting flange 7 is connected with the end face of flange of ball valve 15 1 sides by gasket seal 16 and bolt connecting mode; The end face of flange of ball valve 15 opposite sides is connected with filler flange 6 one ends by gasket seal 16 and bolt connecting mode; Filler flange 6 other ends are connected with boatswain chair 4, and simultaneously, 4 of filler flange 6 end faces and boatswain chairs are provided with hold-down grid assembly 5, and hold-down grid assembly 5 is fixed on filler flange 6 end faces; Boatswain chair 4 inner circles are fixedly installed measuring tube 10, measuring tube capping 11 and lower securing member 13 internal chamber wall phase crimping that measuring tube 10 1 ends pass successively hold-down grid assembly 5, filler flange 6, ball valve 15, gasket seal 16, mounting flange 7, tested pipeline 1 and arrange by this end face; Measuring tube 10 other ends pass boatswain chair 4 and are connected with valve head assembly 2, and valve head assembly 2 end face centers are provided with plug 3.In the actual implementation process of patent, be provided with positive pressure guiding pipe 8, negative pressure guiding pipe 9 in the measuring tube 10; Being bolted mode between boatswain chair 4 and filler flange 6 end faces is flexibly connected, simultaneously, because measuring tube 10 and hold-down grid assembly 5, filler flange 6, ball valve 15, gasket seal 16, mounting flange 7, tested pipeline 1,13 of lower securing members are movable connection method, so, when flowmeter goes wrong, only need to close ball valve 15 and turn on boatswain chair 4 and filler flange 6 end faces between bolt, measuring tube 10 can be taken out from flowmeter, convenient for maintaining does not affect the operation of whole system in the time of time saving and energy saving.
Those skilled in the art's simple change and replacement all are within the protection domain of the present utility model in this area.
