Description
Technical field
The utility model belongs to valve technology field, relates to a kind of strainer valve, particularly a kind of water purifying strainer valve with backwashing function.
Background technology
In carrying the pipeline of liquid,, need dress add filter for filtering is blended in solid impurity in the liquid.Generally, filter can gather impurity on the filter core and influences liquid communication in use for some time.For filter can normally use, must often filter core be removed cleaning, so not only increase maintenance load, also often influence the operate as normal of the device that uses liquid.
At present, solution to the problems described above is that filter is carried out backwash.Number be 87209861 a kind of " the integrated back flush filters " that provide as Chinese patent application, this filter is an one with filter and reversal valve collection, be connected as monolithic element and standard pipe fitting are convenient, its reversal valve is made of valve body, spool, valve gap, seal, handle and securing member, and filter is made of valve body, filter core and the shell of reversal valve.Reversal valve have three interfaces provide respectively liquid into and out of with drain impurity.But the spool of its reversal valve has three independently passages, in fact just in a valve body spool is made up, and also seems complicated and heavy huge.Also there is problem similarly in other the strainer valve with backwashing function.
Summary of the invention
The purpose of this utility model is to have above-mentioned problem at existing water purifying strainer valve, a kind of simple in structure, good filtration effect is provided, has the water purifying strainer valve of backwashing function.
The purpose of this utility model can realize by following technical proposal: a kind of water purifying strainer valve, comprise valve body, handwheel and the valve rod that is arranged in the valve body, one end of this valve rod is connected with spool, the other end of valve rod passes valve body and handwheel is connected, have the outlet pipe and the water inlet pipe that are connected as a single entity with valve body on the valve body, the intracavity inter-connection of above-mentioned water inlet pipe and outlet pipe and valve body, on inner chamber, be provided with the seal that can form sealing with spool, it is characterized in that, near in the inner chamber of outlet pipe filtration is being set, be provided with the backwash passage between described valve body and the valve rod, this backwash passage one port is communicated with inner chamber and can forms sealing with spool, the another port passes the valve body backwash tube outer with being arranged on valve body and is connected, the other end of backwash tube is connected the side of outlet pipe and communicates with outlet pipe, on the valve body between seal and the filtration, be provided with and be communicated with inner chamber, the commutating structure of closing backwash passage and blow-off pipe simultaneously or only closing seal is set on the above-mentioned spool for the external blow-off pipe of impurity dump valve.
This water purifying strainer valve is connected in the pipeline, be used for being blended in the solid impurity in the liquid in the filter pipe and the impurity that will accumulate on the filter by the function of backwash that the impurity dump valve is external.During use, rotating handwheel makes commutating structure and backwash passway formation sealing while spool on the spool also can close end-of-the-pipe, liquid only can flow to from seal, flows out to outlet pipe after the structure after filtration by inner chamber again, is blended in the impurity in the liquid and is blocked in a side of filtration.Gather more for a long time at impurity, the backward rotation handwheel, make commutating structure and seal on the spool form sealing, backwash passage and blow-off pipe are open-minded, and liquid only can flow to from the backwash passway, flows to outlet pipe by backwash tube, because outlet pipe goes out pipeline and is in closed state, liquid can only flow to filtration, thereby flushing accumulates in the impurity on the filtration, and the impurity that washes can be external from the blow-off pipe dump valve.
In above-mentioned water purifying strainer valve, described commutating structure comprise the pressing plate that is fixed on the spool lower end and with the blowdown seal bar of the coaxial setting of valve rod, above-mentioned backwash passway be positioned at pressing plate directly over, above-mentioned seal be positioned at pressing plate under, described blowdown seal bar one end can be plugged in the blow-off pipe, and the other end and spool are solidly fixed.
In above-mentioned water purifying strainer valve, be fixed with valve seat in the described valve body, above-mentioned valve rod is a rhizoid bar and is rotatably connected in the valve seat that described spool is by being threaded onto on the valve rod.
Rotation valve rod, spool can move up and down at valve rod, and is fixed on the pressing plate of spool lower end and the blowdown seal bar also can move up and down.When pressing plate and backwash passway contacted and form sealing, the blowdown seal bar was plugged in the blow-off pipe, and to close the backwash passage, water will flow to from seal; When pressing plate contacted and form sealing with seal, the blowdown seal bar broke away from blow-off pipe, and water will flow to from the backwash passway, flows out from blow-off pipe at last.
In above-mentioned water purifying strainer valve, described valve seat is cylindric and sidepiece has through hole, and the outer end of this valve seat is connected with valve seal, seals between the inner and the valve body, and above-mentioned spool passes the internal diameter of the external diameter of the inner and spool less than valve seat the inner.In when recoil, water can be from flowing through between spool and the valve seat and flowing to backwash tube from the through hole of the side of valve seat.
In above-mentioned water purifying strainer valve, described filtration comprises filter screen, activated carbon and triiodide resin, and the outermost of the both sides of this filtration is filter screen, is activated carbon between two filter screens, is triiodide resin between filter screen and active carbon.Can be filled into different types of impurity by these three kinds of filtering materials, strengthen filter effect.
In above-mentioned water purifying strainer valve, the both sides up and down of described pressing plate are with gasket seal respectively.Can increase the sealing of pressing plate and seal or backwash mouth by pad.
In above-mentioned water purifying strainer valve, be provided with sealing ring between described blowdown seal bar and the blow-off pipe.
In above-mentioned water purifying strainer valve, described backwash tube is made by transparent material.
Compared with prior art, this water purifying strainer valve has following advantage:
1, form a filtration channel by seal and outlet pipe in valve body, form a backwash passage outside valve body, pipeline simplifies the structure; Only just can commutate simultaneously, simplify the structure of spool, make this water purifying strainer valve simple in structure by pressing plate.
2, using seal approach such as gasket seal and sealing ring is that this water purifying strainer valve has excellent sealing.
3, backwash tube is made the process that can allow the user observe backwash by transparent material, has increased the convenience of using.
