Abstract
The utility model provides a manual multi-way rotary valve which is used for controlling fluids to change directions, which is characterized in that improvements are made on the basis of the existing manual rotary valve; a feed inlet is arranged on the lower part of a valve seat; a plurality of feed outlet are arranged on the circumferential wall of the valve; a valve core is provided with a valve chamber which is communicated with the feed inlet and a through hole which is corresponding to the feed outlet; the valve core is tightly pressed on the valve seat through a press cover and a fixing nut. Through the improvement, the valve seat can be provided with more feed outlets, thus the disadvantage of convenient manual rotary valve use when channels are more than four is overcome. The utility model has the advantages of simple structure, multiply channels and convenient operation.
Description
The utility model belongs to position control valve, particularly a kind of manually many logical rotary valves.Be applicable to the commutation of lowpressure stream moving medium.
As everyone knows, on the pipeline of small flow low pressure, often adopt manual rotary valve as the distribution of flowing medium, the threeway or the four-way valve of commutation.Yet because structure is limit, path surpasses at 5 o'clock just to be difficult to realize, must be by the device of shifting block type distributor.And adopt that the device of shifting block type distributor has brought that volume is big, the defective of consumption material and inconvenient operation, this is the deficiency of existing manual rotary valve just.
The purpose of this utility model is to overcome the deficiency of existing manual rotary valve, and a kind of simple in structure, easy to operate and path manually many logical rotary valves how are provided.
Task of the present utility model is achieved in that this manual multiple-way valve includes valve seat, spool, handle and elastic positioning device, but done following improvement: have a material feeding mouth in the valve seat bottom, and on its perisporium, evenly have a discharge port, in spool, have a valve pocket that opens wide downwards, on the spool cylndrical surface, have one can be communicated with valve pocket and with the corresponding through hole of discharge port, be provided with a location gland on spool top, this gland is pressed on the spool by a set screw nut that is connected with valve seat.
Below in conjunction with accompanying drawing structure of the present utility model is further described.
Fig. 1 is the sectional view of a kind of concrete structure of the utility model.
As shown in Figure 1, be provided with material feeding mouth (7) in the bottom of valve seat (6), and evenly have a plurality of discharge ports (4) on its perisporium, its number can be decided as required, is suitable with three to eight generally.Spool (5) is arranged in the valve seat (6), and its valve pocket (8) opens wide downwards, is communicated with discharge port (7), and its through hole (9) is communicated with discharge port (4) and valve pocket (8).Gland (12) is arranged on spool (5) top, is positioned on the valve seat (6) with positioning dowel (10), and is connected with valve seat (6) with set screw nut (11) gland (12) is pressed on the spool (5).Handle (13) directly is contained in spool (5) top, and elastic positioning device (1) is housed thereon, can cooperate with the positioning pit on the gland (12) to realize spool (8) location.In order to improve the sealing of this manual multiple-way valve, can wear-resisting, a corrosion resistant polytetrafluoroethylene gasket (2 and 3) be set respectively between set screw nut (11) and the gland (12) and between gland (12) and the spool (5).
From structure of the present utility model as can be known, because material feeding mouth (7) is arranged on the bottom of valve seat (6), make the perisporium of valve seat (6) that a plurality of discharge ports (4) can be set, as long as rotate the spool (5) that is provided with valve pocket (8), the direction that just can the control flows moving medium flows out, thereby overcome the deficiency of existing manual rotary valve, can realize many logical requirements, keep simple in structure, the easy to operate advantage of manual rotary valve again.
The utility model is suitable for pipeline as the multichannel distribution of flowing medium, the usefulness of commutation.
Claims (2)
1, a kind of manually many logical rotary valves, include valve seat (6), spool (5), handle (13) and elastic positioning device (1), it is characterized in that having a material feeding mouth (7) in valve seat (6) bottom, on its perisporium, evenly have discharge port (4), in spool (5), have a valve pocket (8) that opens wide downwards, peripheral wall at spool (5) has a connection valve pocket (8) and the through hole (9) corresponding with discharge port (4), be provided with a location gland (12) on spool (5) top, this location gland (12) is pressed on the spool (5) by a set screw nut (11) that is connected with valve seat (6).
2, manually many logical rotary valves according to claim 1 is characterized in that being respectively equipped with a polytetrafluoroethylene gasket (2 and 3) between gland (12) and set screw nut (11) and spool (5).
