Abstract
The utility model discloses an abrasionproof decreases butterfly valve, which comprises the following components: a valve body, be equipped with axle sleeve and mounting hole on the valve body, be provided with the valve block in the valve body, valve block and first valve rod fixed connection, fixedly connected with opens and close the handle on the first valve rod, the inside second valve rod that is equipped with of first valve rod, second valve rod top is provided with presses the handle, and second valve rod bottom and spring fixed connection, be provided with the connecting rod tooth on the second valve rod, on the second valve rod of connecting rod tooth top and below respectively fixed mounting stir the piece, the connecting rod tooth is connected with the ratchet meshing, ratchet and pawl joint. This abrasionproof decreases butterfly valve through set up even a plurality of mounting holes on the valve body circumference, can effectively prevent harmful displacement of disk seat, simultaneously needn't rotate the valve block just can open the valve block tripe, has avoided the friction of opening and close of valve block and sealing washer, and the effectual leakproofness of protecting the butterfly valve has lengthened the life of butterfly valve.
Description
Technical field
This utility model belongs to butterfly valve technical field, is specifically related to a kind of anti-wear butterfly valve.
Background technology
Existing butterfly valve generally comprises valve body, valve plate, valve rod, valve seat it is provided with in valve body, valve seat can be made up of rigid material or flexible material, valve plate is made up of spool and bar set, spool can contact with valve base sealing, and in valve rod insertion rod set, when valve rod rotates, valve plate follows rotation, make spool contact with valve base sealing or valve seat disengages, it is achieved being turned on and off of butterfly valve.When butterfly valve is turned on and off, can produce friction between spool and valve seat, its sealing surface can produce abrasion, makes the sealing property of butterfly valve decline, and affects the service life of butterfly valve, and the returning face plate of existing butterfly valve arranges and can not the most effectively control media flow.
Utility model content
The purpose of this utility model is to provide a kind of anti-wear butterfly valve, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model following technical scheme of offer: a kind of anti-wear butterfly valve, including valve body, described valve body is provided with axle sleeve and installing hole, it is provided with valve block in described valve body, described valve block and the fixing connection of the first valve rod, it is fixedly connected with opening-closing handle on described first valve rod, described first stem internal is provided with the second valve rod, described second valve stem top is provided with press handle, and second stem bottom and spring fixing be connected, it is provided with rod teeth on described second valve rod, sliding piece it is installed with respectively on the second valve rod above and below described rod teeth, described rod teeth is connected with ratchet engagement, described ratchet and lock pawl clamping.
Preferably, inside described valve body, it is provided with sealing ring, and valve body is coordinated with valve block sealing by sealing ring.
Preferably, described valve block is louver structure.
Preferably, described first valve rod is the cylindrical structure of hollow.
Technique effect of the present utility model and advantage: this anti-wear butterfly valve, by arranging the first valve rod and opening-closing handle, this mechanism can control valve block fully open when the big flow of needs；By at valve body uniform multiple installing holes provided circumferentially about, this structure can effectively prevent the harmful drift of valve seat；By the ratchet being arranged on the second valve rod and even ratch etc.; during operation when press handle is pressed; second valve rod moves down; rod teeth is made to engage one tooth of rotation with ratchet; the ratchet gear teeth are blocked by lock pawl; thus can prevent ratchet from inverting; the dynamics pressed down is different; the BAIYE making valve block opens different angles; achieve that flow in various degree, it is not necessary to rotate valve block and just can open, it is to avoid valve block and the keying friction of sealing ring; it is effectively protected the sealing of butterfly valve, extends the service life of butterfly valve.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 valve body, 11 axle sleeves, 12 installing holes, 2 valve blocks, 3 first valve rods, 4 opening-closing handles, 5 second valve rods, 51 press handles, 52 springs, 53 rod teeth, 54 sliding pieces, 55 ratchets, 56 lock pawls, 6 sealing rings.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
nullThis utility model provides the anti-wear butterfly valve of one as shown in Figure 1，Including valve body 1，Described valve body 1 is provided with axle sleeve 11 and installing hole 12，It is provided with valve block 2 in described valve body 1，Described valve block 2 is fixing with the first valve rod 3 to be connected，It is fixedly connected with opening-closing handle 4 on described first valve rod 3，Described first valve rod 3 is internal is provided with the second valve rod 5，Described second valve rod 5 top is provided with press handle 51，And second fixing with spring 52 bottom valve rod 5 be connected，It is provided with rod teeth 53 on described second valve rod 5，Sliding piece 54 it is installed with respectively on the second valve rod 5 above and below described rod teeth 53，Described rod teeth 53 is connected with ratchet 55 engagement，Described ratchet 55 and lock pawl 56 clamping，It is provided with sealing ring 6 inside described valve body 1，And valve body 1 is coordinated with valve block 2 sealing by sealing ring 6，Described valve block 2 is louver structure，Described first valve rod 3 is the cylindrical structure of hollow.
This anti-wear butterfly valve, by arranging the first valve rod 3 and opening-closing handle 4, this mechanism can control valve block 2 fully open when the big flow of needs；By at valve body 1 uniform multiple installing holes 12 provided circumferentially about, this structure can effectively prevent the harmful drift of valve body 1；By the ratchet 55 being arranged on the second valve rod 5 and rod teeth 53 etc.; during operation when press handle 51 is pressed; second valve rod 5 moves down; rod teeth 53 is made to engage one tooth of rotation with ratchet 55; the gear teeth of ratchet 55 are blocked by lock pawl 56; thus can prevent ratchet 55 from inverting; the dynamics pressed down is different; the BAIYE making valve block 2 opens different angles; achieve that flow in various degree, it is not necessary to rotate valve block 2 and just can open, it is to avoid valve block 2 and the keying friction of sealing ring 6; it is effectively protected the sealing of butterfly valve, extends the service life of butterfly valve.
Last it is noted that the foregoing is only preferred embodiment of the present utility model; it is not limited to this utility model; although this utility model being described in detail with reference to previous embodiment; for a person skilled in the art; technical scheme described in foregoing embodiments still can be modified by it; or wherein portion of techniques feature is carried out equivalent; all within spirit of the present utility model and principle; the any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
