Abstract
A sealed flushing type baiting valve comprises a valve body and a valve seat, wherein a valve clack which is correspondingly matched with the valve seat is connected to the end part of a valve rod, an air inlet channel which is connected with an external air supply pipe is arranged in the valve rod, an air outlet channel which is communicated with the air inlet channel is arranged in the valve clack, and an outlet of the air outlet channel is positioned on a sealed matching surface of the valve clack to form a sealed surface flushing structure. The utility model discloses a rational in infrastructure ingenious, utilize inlet channel and outlet channel directly to channel into on the sealed fitting surface of valve clack, disk seat with steam or other cleaners, convenient operation washes direct high-efficient, need not to dismantle the valve, also need not the technology pipeline and parks the maintenance on purpose, greatly reduced the influence to normal production.
Description
The technical field is as follows: the utility model relates to a baiting valve.
Background art: the baiting valve is generally used for emptying media in a process pipeline, but many media are relatively viscous and easy to crystallize and attach to the sealing matching surface of a valve clack and a valve seat of the baiting valve, and the sealing performance is directly influenced. If the sealing matching surface of the valve clack needs to be cleaned by a common emptying valve, the valve is required to be disassembled, and a process pipeline is required to be specially stopped for maintenance, so that the influence on normal production is large.
The invention content is as follows: to the deficiency of the prior art, the utility model provides a wash convenient sealed flushing type baiting valve.
The utility model discloses a valve body and disk seat correspond the complex valve clack with the disk seat and connect at the valve rod tip, are equipped with the inlet channel who connects the external air supply pipe in the valve rod, are equipped with the outlet channel who communicates with inlet channel in the valve clack, and outlet channel's export is located the sealed fitting surface of valve clack, forms sealed face and washes the structure.
The utility model discloses a rational in infrastructure ingenious, utilize inlet channel and outlet channel directly to channel into on the sealed fitting surface of valve clack, disk seat with steam or other cleaners, convenient operation washes direct high-efficient, need not to dismantle the valve, also need not the technology pipeline and parks the maintenance on purpose, greatly reduced the influence to normal production.
The invention is further described with reference to the following figures and examples.
Description of the drawings: fig. 1 is a schematic diagram of the main structure of the embodiment.
Figure 2 is a schematic section a-a of the valve flap of figure 1.
The specific implementation mode is as follows: as shown in fig. 1 and 2, a valve seat 2 is provided in a valve body 1, and a valve flap 3 corresponding to the valve seat 2 is connected to an end of a valve stem 4. An air inlet channel 6 connected with an external air supply pipe 5 is arranged in the valve rod 4, an air outlet channel 7 communicated with the air inlet channel 3 is arranged in the valve clack 3, and an outlet of the air outlet channel 7 is positioned on a sealing matching surface of the valve clack 3 to form a sealing surface flushing structure. The valve clack 3 of this embodiment is circular, and the outlet channel 7 in the valve clack 3 has many, is radial radiation distribution, and the export equipartition of each outlet channel 7 is on the sealed fitting surface of valve clack 3.
When the valve is opened, the valve rod 4 drives the valve clack 3 to move downwards together, the valve clack 3 and the valve seat 2 are separated from sealing fit, and the discharging channel is opened. If crystal attachments on the sealing matching surface of the valve clack 3 need to be cleaned, steam or other cleaning agents can be introduced from the external air supply pipe 5, and the steam is directly introduced to the sealing matching surface of the valve clack 3 and the valve seat 2 through the air inlet channel 6 and the air outlet channel 7, so that the cleaning is direct and efficient. An air inlet control valve 8 is typically connected to the external air supply pipe 5 to facilitate control of the flushing time and flow rate.
