Fig. 1 is that the structure of air type damper of the present utility model is cutd open figure.
Fig. 2 is the structural representation of medicine adding device of the present utility model.
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment
Obviously, the many modifications and variations that those skilled in the art do based on aim of the present utility model belong to protection domain of the present utility model.
Embodiment 1: as shown in Figure 1 and Figure 2, a kind of medicine adding device, liquid inlet pipe 5 is connected with the import of pump 6, drain pipe 7 is connected with the outlet of pump 6, on drain pipe 7, connection damper 10, and damper 10 arranges perpendicular to drain pipe 7, and the nipple joint 3 of damper 10 is communicated with drain pipe 7 down.
The nipple joint 3 of damper 10 is communicated with drain pipe 7 by ball valve 8, and ball valve 8 is communicated with drain pipe 7 vertically upward.By ball valve 8, control the break-make of damper and drain pipe 7.Damper 10 is connected with ball valve 8 by connecting short section 9.
In the medicine adding device being formed by liquid inlet pipe 5, pump 6 and drain pipe 7, in order to eliminate pump 6, move the pulsation of the pressure versus flow producing, a ball valve 8 is installed vertically upward on the drain pipe 7 of medicine adding device, ball valve 8 connects damper 10 of the present utility model by connecting short section 9, and the nipple joint 3 that guarantees damper 10 of the present utility model downwards and be vertically connected on drain pipe 7, like this damper 10 in air and the air of carrying secretly during dosing can hoard in the cavity of damper 10, damper 10 can be air type damper.
Damper 10 comprises: in housing 1, have cavity 2, have and be communicated with the inside and outside opening of housing 1 on housing 1; Nipple joint 3 is fixedly connected with the opening of housing 1, and nipple joint 3 has the inside and outside axial nipple joint 301 of connection housing, and nipple joint 301 has through hole, and the outer circumferential face of nipple joint 301 has screw thread.
As above-described embodiment preferably, its middle shell 1 comprises: one end of cylindrical shell 101 is sealed by upper cover 102, the other end of cylindrical shell 101 is sealed by lower seal head 103, opening is opened on lower seal head 103.Between cylindrical shell 101 and upper cover 102 and lower seal head 103 preferably by being welded to connect.Nipple joint 3 is welded to connect with housing 1.Adopt welding manner integral body more firm, good seal performance, is convenient to manufacture.And with less material.As there is the problems such as expense raw material or manufacturing process complexity in other modes such as employing is threaded.
Nipple joint 3 has thin portion and thick portion, between thin portion and thick portion, forms step, and thin portion, in opening inserts housing, has screw thread on the outer circumferential face of thick portion.Nipple joint 3 can be more firm after welding with housing 1 like this.The thin portion of nipple joint 3 is threaded with the opening of housing 1.The one, can increase fastness between the two, moreover first nipple joint 3 is threaded with housing 1, utilize welding operation thereafter.
