Description
Technical field
The utility model relates to the valving in the water treatment procedure, relates in particular to a kind of and pneumatic base plate valve of transforming newly-built for the filter tank.
Background technique
The siphon filter that uses in the water treatment technology is a kind of form of rapid filter, and its feature is to utilize the siphon principle water inlet and drain washed-out sand water, has therefore saved two gates.In addition, it utilizes the water level in small resistance water wiring system and pond itself to carry out backwash, does not need to establish in addition flush box or water pump, more easily utilizes waterpower in addition, controls the operation in pond automatically, so be applied morely.
But siphon filter limits because of washing condition, often uses just not occur degradation phenomenon under the increase of filtering layer clay content, shortening filter cycle, washing time prolongation, the water yield for a long time.In order to improve the siphon filter developing result, can adopt air-water backwashing technology preferably, rinse stage generally adopt gas dash-air water connection dashes-water dashes three processes, gas is broken through journey and need be cut off the total canal of clear water and wash being communicated with of filter grid, avoids the flushing out air crossfire to cause the backwash rate deficiency to the total canal of clear water.In order to solve the total canal of clear water and the isolation of flushing filter grid in rinse stage, if adopt traditional valve plate, carry out as Pneumatic butterfly valve, Pneumatic gate valve, this kind valve body and actuator all are immersed in the water, can reduce the working life of valve plate, the maintenance inconvenience is installed, also can pollute filtered water quality.
At present, in transformation field, filter tank, introduced all two kinds of valves on the water surface of actuator, a kind of is Pneumatic reverse turning bed valve, and a kind of is to draw to cover valve.This two kinds of valves have all well solved actuator and have been immersed in problem in the water.The physical dimension of the former turnover panel valve body is long strip, and when the length of turnover panel valve body is big, the follower link that is attached thereto can't guarantee that turnover panel valve body complete shut-down puts in place and seals intact; The latter's valve plate and execution architecture situation about being not closed completely occurs easily for being rigidly connected.
Summary of the invention
For addressing the above problem, main purpose of the present utility model provides a kind of pneumatic base plate valve of good seal performance.
The pneumatic base plate valve that the utility model provides is used for partition and the connection of pond fluid passage, comprises cylinder, piston, piston rod, valve plate and valve seat; Cylinder is positioned at more than the liquid level of pond liquid, and piston links to each other with piston rod, and piston rod links to each other with valve plate; Valve plate and valve seat are positioned at below the liquid level, are provided with fluid passage in the valve seat, and valve plate can be mobile between the position of closed liquid passage and unlatching fluid passage; Valve seat is arranged on the dividing plate that is positioned at basin bottom, the axis of fluid passage and dividing plate approximate vertical, valve plate and dividing plate almost parallel; Be provided with universal joint between piston rod and the valve plate.
The pneumatic base plate valve of technique scheme, owing to be provided with universal joint between piston rod and valve plate, even dividing plate is not to be in level or valve cup rim slightly not at ordinary times, the existence of universal joint can guarantee that still valve plate is to the excellent sealing of fluid passage.
Further, the pneumatic base plate valve that the utility model provides, piston rod comprises controlling device, controlling device is come the length of regulating piston bar by the cooperation between the screw thread;
Further, above-mentioned controlling device also comprises locking nut.
Technique scheme can realize the fine setting of piston rod length by controlling device.
Further, the pneumatic base plate valve that the utility model provides, valve seat and valve plate are circle.Valve plate and the valve seat construction of round structure are simpler, and sealability is better.
More excellent, the pneumatic base plate valve that the utility model provides is provided with seal ring between valve plate and valve seat, can better guarantee sealability.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment's pneumatic base plate valve.
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
Following examples introduce in the process at concrete structure or component, only understand of the present utility model with reference to the property illustration as those skilled in the art, those skilled in the art can also design or technical scope or the various of technical spirit that patterning is not exceeded the utility model are equal to or the similar techniques feature under the enlightenment of embodiment's description technique scheme.Thus, be unfavorable if limit the protection domain that the utility model claim includes with this exemplary illustration.Be equal to or be similar to the protection domain that the technical solution of the utility model still belongs to the utility model claim.
As shown in Figure 1, embodiment's pneumatic base plate valve is installed in the siphon filter, comprise the straight line cylinder 10 by compressed air-driven, be provided with piston (invisible among the figure) in the cylinder 10, cylinder 10 is supported on the cylinder support 20, piston links to each other with piston rod 50, and piston rod 50 is provided with controlling device 40 and locking nut 30, and above-mentioned cylinder 10, piston, cylinder support 20, controlling device 40 and locking nut 30 all are positioned at the liquid level in filter tank more than 100.Be provided with the dividing plate 200 of level in the bottom of siphon filter, circular valve seat 90 is fixed on the dividing plate 200, is provided with circular fluid passage in the valve seat 90, the axis of fluid passage and divider upright; Above valve seat 90, be provided with circular valve plate 70, be provided with seal ring 80 between valve seat 90 and the valve plate 70; Valve plate 70 links to each other with piston rod 50 by universal joint 60, universal joint 60 is arranged on the central position of valve plate 70, because the existence of universal joint 60, valve plate 70 is actually and can freely swings around the center, but be not subjected under the external force effect, the plane at valve plate 70 places keeps parallel with dividing plate 200 basically.Above-mentioned valve plate 70, valve seat 90, seal ring 80 and universal joint 60 all are in liquid level below 100.
Controlling device 40 comprises that inwall has the sleeve of screw thread, piston rod 50 is positioned at the screw thread that also has on the outer wall of part of sleeve inner with the sleeve lining coupling, by the turn sleeve, can reconcile the length of piston rod 50, then by sleeve top locking nut 30, the length of the piston rod 50 that regulates is locked.Controlling device 40 and locking nut 30 match, and can realize the fine setting of piston rod 50 length, and final purpose is the sealing that better realizes between valve plate 70 and the valve seat 90.Certainly, locking nut 30 not necessarily; In addition, controlling device also can adopt other different modes, as long as can realize the fine setting of piston rod length.
Pneumatic base plate valve working process is as follows: when needs are opened fluid passage, under the effect of cylinder 10 and piston, drive piston rod 50 and move up, piston rod 50 is pulled away from valve seat 90 with valve plate 70, and fluid passage is opened; When needs closing liquid passage, cylinder 10 and piston acting in conjunction drive piston rod 50 and move down, because the effect of universal joint 60, valve plate 60 is also non-rigid but can swing several angle, even valve seat 90 is low dip slightly, valve plate 70 also can be by the edge of the complete seal valve seat 70 of suitable adjustment, thereby closes the fluid passage in the valve seat 90 fully.
