Abstract
The utility model discloses a pneumatic no-block permeable gate valve, comprising an upper valve (1), a lower valve (2), a bracket (35), a cylinder (42), a flash board (16) coupled on a piston rod (19) of the cylinder, a seal seat (3) between the upper, lower valves and the flash board and a seal seat cover (4), wherein the upper valve is connected with the lower valve by fastening assemblies comprising bolts (39) and nuts (41) and fillers (8) are filled in filler containers between the ends of the upper, lower valves and the flash board and pressed by filler pressure covers (9) and an 'O' shaped ring (5) is arranged at the end of the seal seat. The upper, lower valves do not deform and 'no valve cavity' structures are present between the upper, lower valves and the flash board by the pretension elastic force of the 'O' shaped ring and the filler inbuilt function, therefore the bottom of the valve and the inner cavity are not blocked by solid and medium with fiber and sundries and the valve is normally shut off and the clean and maintenance process is simple with no need for disassembling the valve often. The pneumatic no-block permeable gate valve can be widely used for industries such as paper making, mining.
Description
One, technical field
The utility model relates to a kind of valve, specifically relates to a kind of pneumatic penetration gate valve.
Two, background technique
At present, pneumatic penetration gate valve is a kind of valve of using do switching, being generally welding procedure between its upper and lower valve body connects, the valve body easy deformation, the valve pocket gap is bigger, thereby valve body bottom and inner chamber are stopped up by the medium of solid and band fiber, foreign material material easily, cause valve closing not tight (as the stuck difficulty of then closing).Can cause valve can't normally close, move inefficacy after the long-term accumulated, under the thrust of its cylinder, whole valve can be destroyed, so need often will clear up, safeguard after the valve dismounting, maintenance workload be big, maintenance difficult, cost increase.
Three, model utility content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of pneumatic no jam penetration gate valve that valve pocket, medium can not stop up that do not have is provided.
The purpose of this utility model realizes by following technical solution: a kind of pneumatic no jam penetration gate valve, comprise upper valve body, following valve body, support, cylinder, be associated with flashboard on the piston rod of cylinder, sealing seat, sealing flap are housed between upper and lower valve body and the flashboard, link by some fastener assemblies that constitute by bolt, nut between described upper valve body and the following valve body, filler between upper and lower valve body two end part and the flashboard is equipped with filler in containing, and using Gland to push down, round section joint ring is equipped with in the end of sealing seat.
After adopting the utility model structure, owing to link by fastener assembly between the upper and lower valve body, upper and lower valve body can be out of shape, and because the pretension elastic force and the built-in effect of filler of round section joint ring, making between upper and lower valve body and the flashboard is " no valve pocket " structure, thereby makes valve body bottom and inner chamber can and not be with the medium of fiber, foreign material material to stop up by solid, valve closing is normal, no longer need often to dismantle valve and clear up, safeguard simply, can be widely used in industries such as papermaking, system ore deposit.
Four, description of drawings
Below in conjunction with accompanying drawing and mode of execution the utility model is described in further detail.
Fig. 1 is the structural representation of the pneumatic no jam penetration gate valve of the utility model.
Fig. 2 is the sectional view of Fig. 1.
Fig. 3 is " no valve pocket " structural representation between upper and lower valve body of the utility model and the flashboard.
Fig. 4 is two halves formula seperating vale body structure schematic representation for the utility model upper valve body with following valve body.
Five, embodiment
Referring to figs. 1 through Fig. 4 as can be known, the pneumatic no jam penetration gate valve of the utility model, comprise upper valve body 1, following valve body 2, support 35, cylinder 42, (by connecting rod 17 and connecting pin 18) is associated with flashboard 16 on the piston rod 19 of cylinder 42, on, (be between upper valve body middle part and the flashboard between following valve body (middle part) and the flashboard 16, between following valve body middle part and the flashboard) sealing seat 3 is housed, sealing flap 4, pass through some between described upper valve body 1 and the following valve body 2 by bolt 39, the fastener assembly that nut 41 (and plain washer 40) constitutes links, on, filler between following valve body two end part and the flashboard is equipped with filler 8 in containing, and using Gland 9 to push down, round section joint ring 5 is equipped with in the end of sealing seat 3.
Wherein, the penetration gate valve be by a flashboard that passes valve body as closure member, body cavity is the gate valve of penetration; Cylinder 42 is made of upper cylinder cover 22, piston 21, following cylinder cap 20, piston rod 19, bearing 48 etc.; Induction switch support 54 also is equipped with in the outer end of connecting rod 17.This penetration gate valve can be designed to one-way sealing, also can be designed to two way sealed, described sealing seat 3 can be designed to floating bushing cartridge type structure, the round section joint ring that its end is provided with had both sealed also when the prefastening force spring use, the pressure of medium was pushed flashboard to sealing seat when flashboard cut out, the round section joint ring of sealing seat end can limit sealing seat and draw back and allow, make sealing seat be close to flashboard, reach sealing effect, make to be " no valve pocket " structure (as shown in Figure 3) between upper and lower valve body and the flashboard.
As shown in Figure 4, described upper valve body 1 separates valve body with following valve body 2 for the two halves formula, and upper and lower valve body designs for symplex structure, upper and lower valve body is detachable, easy to maintenance, form no gap valve body and cooperate, to solve the problem of the easy jam of valve pocket, simultaneously, only need cast half of valve body during casting, so just solve the problem of casting difficulty.
Claims (3)
1. pneumatic no jam penetration gate valve, comprise upper valve body (1), following valve body (2), support (35), cylinder (42), be associated with flashboard (16) on the piston rod (19) of cylinder (42), on, sealing seat (3) is housed between following valve body and the flashboard, sealing flap (4), it is characterized in that: pass through some between described upper valve body (1) and the following valve body (2) by bolt (39), the fastener assembly that nut (41) constitutes links, on, filler between following valve body two end part and the flashboard is equipped with filler (8) in containing, and using Gland (9) to push down, " 0 " shape circle (5) is equipped with in the end of sealing seat (3).
