Further, this pulp water gate valve also includes y-type seal ring and trim ring, and described y-type seal ring and trim ring are sheathed on described valve shaft and between described valve shaft and valve gap, and described trim ring pushes against described y-type seal ring。
Further, the height of described valve body lumen is more than or equal to the height of described flashboard。
Further, this pulp water gate valve also includes actuator, and described actuator is located at described valve gap top and connects the top of described valve shaft。
Further, described actuator is on or the operation handwheel of Shuttoff Valve。
Further, the inlet side passage of described valve body is venturi type undergauge passage。
Owing to this utility model pulp water gate valve have employed technique scheme, namely the valve gap of this pulp water gate valve is located at valve body end face by bolt and forms valve body lumen with valve body, valve shaft penetrates valve gap and is arranged in valve body intracavity, valve shaft bottom is connected with flashboard top by falcon groove, valve shaft drives flashboard to make flashboard between valve body lumen or the valve seat of valve body, bottom flashboard, the inlet side at valve body is provided with guiding gutter, guiding gutter is positioned at below the valve seat of valve body, body base is provided with ash pit at outlet side, and ash pit is positioned at below the valve seat of valve body。This pulp water gate valve overcomes the defect of traditional gate valve, significantly improves the service life on the serious pipeline of erosion, extends the cycle that maintenance of valve is changed, reduces induction system operating cost, it is ensured that the transmitting of pipeline medium。
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of this utility model pulp water gate valve；
Fig. 2 is A direction view (only flashboard) in Fig. 1；
Fig. 3 is B-B direction view in Fig. 1；
Fig. 4 is C portion enlarged drawing in Fig. 1。
Detailed description of the invention
Implement such as Fig. 1, shown in Fig. 2 and Fig. 3, this utility model pulp water gate valve includes valve body 1, valve gap 4, valve shaft 3 and flashboard 2, described valve gap 4 is located at described valve body 1 end face by bolt and forms valve body lumen 11 with valve body, described valve shaft 3 penetrates described valve gap 4 and is positioned at described valve body lumen 11, described valve shaft 3 bottom is connected with described flashboard 2 top by falcon groove, during valve opening, described valve shaft 3 drives described flashboard 2 to make flashboard 2 be positioned at described valve body lumen 11, during valve closing, described valve shaft 3 drives described flashboard 2 to make flashboard 2 between the valve seat 12 of described valve body 1, it is characterized in that: bottom described flashboard 2, be provided with guiding gutter 21 at the inlet side of described valve body 1, described guiding gutter 21 is positioned at below the valve seat 12 of described valve body 1, it is provided with ash pit 13 at outlet side bottom described valve body 1, described ash pit 13 is positioned at below the valve seat 12 of described valve body 1。
As shown in Figure 4, it is preferred that this pulp water gate valve also includes y-type seal ring 6 and trim ring 7, described y-type seal ring 6 and trim ring 7 are sheathed on described valve shaft 3 and between described valve shaft 3 and valve gap 4, and described trim ring 7 pushes against described y-type seal ring 6。This pulp water gate valve adds the y-type seal ring fastened by trim ring below the airtight and watertight padding of valve shaft, y-type seal ring can scrape off the impurity that valve shaft adheres in lifting process, avoid the impurity in fluid media (medium) and enter airtight and watertight padding, ensure that the cleaning within airtight and watertight padding, improve sealing property and the service life of airtight and watertight padding。
As shown in Figure 1, it is preferred that, the height of described valve body lumen 11 is more than or equal to the height of described flashboard 2。When valve wide open, flashboard can enter intracavity in valve body, and the fluid media (medium) flowing through valve channel washes away less than flashboard, thus the sealing surface of flashboard is played a very good protection, improves turn-off performance and the service life of valve。
Preferably, this pulp water gate valve also includes actuator 5, and described actuator 5 is located at described valve gap 4 top and connects the top of described valve shaft 3。This actuator can be valve actuator pneumatically or electrically, and when driving valve shaft to rotate, flashboard moves up and down, and flashboard moves downward cut out valve, move upward Open valve。
Preferably, described actuator 5 is on or the operation handwheel 51 of Shuttoff Valve。
Preferably, the inlet side passage of described valve body 1 is venturi type undergauge passage。It can make fluid media (medium) produce to shrink when flowing through this passage, reduces valve body and secondary the washing away of valve seal, it is to avoid valve body is punched through and causes fluid media (medium) to leak。
The valve body of this pulp water gate valve adopts the valve body of integral type, sealing pair is constituted between valve seat and the flashboard of valve body, when flashboard is turned on and off, guiding gutter on flashboard can make the impurity stockpiled bottom body cavity be washed away by fluid media (medium), and discharged by the ash pit of valve outlet side, ensure that flashboard is not hindered by impurity and cuts out and put in place, improve the sealing of valve；It also avoid the abrasion of sealing pair simultaneously, improve the service life of valve。This pulp water gate valve significantly improves valve sealing on the pipeline that erosion is serious and service life, extends the cycle that maintenance of valve is changed, reduces system operation cost, it is ensured that the transmitting of pipeline medium。
This pulp water gate valve is applicable to the two-phase fluid medium pipeline of solid-liquid phase medium, it is particularly applicable among the high wash fluid medium that dregginess is significantly high, and can permanently effective run, reduce media feed system stoppage in transit number of times, reduce replacing valve cost, it is thus achieved that significant economic benefit。
