Detailed Description

Fig. 1 to 4 are preferred embodiments of the present invention, and the present invention will be further explained with reference to fig. 1 to 4.

As shown in fig. 1-2, a condensed water dewatering mechanism for the steam inlet end of a steam sterilizer comprises a sleeve 3, a steam inlet joint 1 is installed on the top of the sleeve 3 through an upper hoop 2, a drain valve 7 is installed on the bottom of the sleeve 3 through a lower hoop 5, a side pipe 4 is led out on the upper portion of the sleeve 3, one end of the side pipe 4 is communicated with the inner cavity of the sleeve 3, and an outlet is arranged at the other end of the side pipe. High-temperature steam enters from the steam inlet joint 1 at the top of the sleeve 3, flows to the bottom of the sleeve 3 from top to bottom, then flows to the top of the sleeve 3 from bottom to top again, and finally flows out from the port of the side pipe 4. During the process that the steam passes through the sleeve 3 in a reciprocating mode, condensed water generated by the steam flows to the drain valve 7 under the action of the gravity of the condensed water and is finally discharged through the drain valve 7.

Referring to fig. 3 to 4, the steam inlet joint 1 is in a circular tube shape, bosses are formed at upper and lower ports thereof, and an inner tube 8 is coaxially fixed at the lower port of the steam inlet joint 1. The sleeve 3 is also in a circular tube shape, and bosses are respectively formed at the upper and lower ports of the sleeve. The steam inlet joint 1 and the inner pipe 8 are arranged in the sleeve 3 from top to bottom, and the boss at the lower port of the steam inlet joint 1 is in butt joint with the boss at the upper port of the sleeve 3, and then the steam inlet joint 1 and the sleeve 3 are fixed through the upper hoop 2. After the steam inlet joint 1 and the sleeve 3 are fixed through the upper hoop 2, the inner pipe 8 extends to the lower part of the sleeve 3. The side pipe 4 is vertically led out from the upper part of the sleeve 3, and two joints which are vertical to each other are arranged at the outer end of the side pipe 4.

Be provided with connecting pipe 6 in the lower port department of sleeve pipe 3, the upper port department of connecting pipe 6 forms the boss, has seted up the external screw thread on the outer wall of connecting pipe 6, and the boss of connecting pipe 6 upper port department is fixed connecting pipe 6 and sleeve pipe 3 through staple bolt 5 down after docking from top to bottom with the boss of sleeve pipe 3 lower port department, fixes in the lower part of sleeve pipe 3 after trap 7 and connecting pipe 6 threaded connection.

Referring to fig. 4, the outer diameter of the inner pipe 8 is smaller than the inner diameter of the casing 3, so that a gap is formed between the outer wall of the inner pipe 8 and the inner wall of the casing 3 after the inner pipe 8 is fastened to the casing 3.

The specific working process and working principle are as follows:

the steam inlet joint 1 is connected with an external steam source, and two outlets on the outer side of the side pipe 4 are connected with a steam inlet of the steam sterilizer. Steam enters from the steam inlet joint 1, flows from top to bottom along the inside of the inner pipe 8, flows to the lower part of the sleeve 3 and flows out from the lower port of the inner pipe 8. The steam flows out from the lower port of the inner pipe 8, then flows through the gap between the inner pipe 8 and the sleeve 3 from bottom to top, flows to the upper part of the sleeve 3, then flows into the side pipe 4, and flows out from the outlet of the side pipe 4.

As mentioned above, the flow distance of the steam is increased by the way that the inner pipe 8 and the sleeve 3 are sleeved in and out, and in the process that the steam passes through the sleeve 3 in a reciprocating manner, the condensed water generated by the steam flows to the drain valve 7 under the action of the gravity of the steam and is finally discharged through the drain valve 7, so that the content of the condensed water in the high-temperature steam is reduced.

While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical substance of the present invention still belong to the protection scope of the technical solution of the present invention.
