Description

Anti-bastard valve

Technical field

The utility model relates to a kind of ball valve, particularly a kind of anti-bastard valve.

Background technique

The ball valve that is used for the processing of this type of special industry such as medicine, chemical industry and food, because the particularity of its interior media, what at first need to ensure is sealing and leakproof; And the special media in the valve body can not mix mutually, the consequence that certain reaction of generation is caused after mixing also is unforeseen, for valve channel inside is kept clean, usually, after in valve channel, passing through a kind of medium, and need be through second kind of medium the time, meeting be cleaned used valve body dismounting or directly be adopted water that it is cleaned, first kind of cleaning way operation inconvenience, prolong process time, though and second kind of cleaning way saves time, spool partly fails to be cleaned completely, and causing also residually on the spool side face has first kind of medium.

Summary of the invention

At the deficiency that prior art exists, the utility model provides a kind of anti-bastard valve of newspaper valve inner cleaning.

For achieving the above object, the utility model provides following technological scheme: a kind of anti-bastard valve, include valve body, valve rod, be located at the medium flow channel in the valve body, the medium flow pass, be provided with the flap placed cavity between medium flow pass and the medium flow channel, be provided with valve rod in this flap placed cavity and be connected, and the globe disk of formation medium flow channel and conducting of medium flow pass or sealing, be provided with in medium flow channel and the medium flow pass and constitute the valve seat of globe disk along medium flow channel or the rotary seal of medium flow pass, described valve body be positioned at the flap placed cavity on, place, following two ends is provided with cleaning solution inflow passage and the cleaning solution outflow passage with the conducting of flap placed cavity respectively.

The upper/lower terminal place that in this valve body is positioned at the flap placed cavity is provided with respectively that cleaning solution with the conducting of flap placed cavity flows into passage and cleaning solution flows out passage, the setting that cleaning solution flows into passage can make things convenient for cleaning solution to enter in the valve body valve inner is cleaned, do not need valve body is taken apart, and globe disk is in and closes and can both clean valve inner during opening state, the cleaning that constantly keeps valve internal, prevent that different medium from mixing mutually, the setting that cleaning solution flows out passage then is to discharge for the cleaning solution that will clean valve body.

The utility model further is set to: described cleaning solution flow into passage be located at valve rod inside and with the passage of the upper end conducting of flap placed cavity, valve rod is provided with the cleaning solution import that flows into the passage conducting with this cleaning solution, described cleaning solution flow out passage and cleaning solution flow into the corresponding setting of passage and respectively with the lower end and the extraneous conducting of flap placed cavity.The cleaning solution import for offer along the valve rod side face some penetrate valve rod and with the through hole of valve rod inner passage conducting.

In this cleaning solution is flowed into passage and be located at valve rod inside, such set-up mode is simple in structure, easy to process, and can not have influence on the sealing of valve body.

The utility model further is set to: be arranged with perpendicular setting on the described valve rod and extend to the outer connecting tube of valve body, the middle part of this connecting tube is provided with the cleaning solution guide channel, the cleaning solution import conducting on this cleaning solution guide channel and the valve rod.

Setting of connecting tube is to drain in the valve body for the cleaning solution with the outside flows into passage through cleaning solution in this, mainly plays the effect of connection.

Below in conjunction with accompanying drawing the utility model is further described:

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment opening state;

Fig. 2 is the structural representation of the utility model embodiment closed condition.

Embodiment

As Fig. 1, a kind of anti-bastard valve shown in Figure 2, include valve body 1, valve rod 2, be located at the medium flow channel 11 in the valve body 1, medium flow pass 12, be provided with flap placed cavity 13 between medium flow pass 12 and the medium flow channel 11, be provided with valve rod 2 in this flap placed cavity 13 and be connected, and the globe disk 14 of formation medium flow channel 11 and 12 conductings of medium flow pass or sealing, be provided with in medium flow channel 11 and the medium flow pass 12 and constitute the valve seat 15 of globe disk 14 along medium flow channel 11 or 12 rotary seals of medium flow pass, valve body 1 is positioned at the upper end 131 of flap placed

cavity

13 and 132 places, lower end and is provided with respectively that cleaning solution with 13 conductings of flap placed cavity flows into passage 3 and cleaning solution flows out passage 4.The setting that cleaning solution flows into passage 3 can make things convenient for cleaning solution to enter valve body 1, valve body 1 inside is cleaned, do not need valve body 1 is taken apart, and globe disk 14 is in and closes and can both clean valve body 1 inside during opening state, constantly keep the cleaning of valve 1 inside, even when changing different media, the preceding medium of planting can not remain in the valve body 1 yet, and cleaning solution mainly cleans the side face of valve body 1; The setting that cleaning solution flows out passage 4 then is to discharge for the cleaning solution that will clean valve body 1.
