Description
Technical field
The utility model relates to valve technology field, especially relates to a kind of backwash filter valve member.
Background technology
Traditional manual backwash filter is handle steel ball direct dynamic structure, and the volume of product is large, and handle is longer simultaneously, and under working condition pressure, operational torque is very large, and the space requirement lever operated in down-hole is larger, uses inconvenience.Special on some pony supports, the installation site of backwash filter is very little, and operating space is very narrow and small, because operation inconvenience, underground labour is often unwilling to operate, and the time one causes filtration core to block for a long time, and impact uses.
Utility model content
Not enough for prior art, technical problem to be solved in the utility model is to provide a kind of backwash filter valve member, to reach object easy and simple to handle.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of backwash filter valve member, comprise valve body, inlet, liquid outlet, feed liquor spool, also comprise one way valve, push rod spool and establish the control oil duct on valve body and reflux mouth, passage is provided with in valve body, the passage end of valve body is inlet, the passage other end is provided with plug, feed liquor spool and push rod spool are located in passage side by side, liquid outlet establishes valve body sidepiece corresponding with feed liquor spool, control oil duct to be connected with the push rod spool promote-side in passage, reflux mouth is between push rod spool and feed liquor spool; The import of described one way valve is connected with inlet, and the outlet of one way valve is connected with control oil duct.
Described one way valve comprises handle, push rod, spring spool, and handle one end and push rod one end are hinged, and the push rod other end is corresponding with spring spool.
Described feed liquor spool comprises the valve pocket be located in passage, is provided with the outer valve cylinder and interior valve cylinder that are nested together, is provided with Compress Spring in the cavity formed between outer valve cylinder and interior valve cylinder in valve pocket.
Described push rod spool comprises piston and push rod, and push rod is located at piston one end, and the piston other end in passage is connected with control oil duct.
The utility model compared with prior art, has the following advantages: backwash is controlled by one way valve, and operational torque is little, and operation lightly facilitates, and feed liquor spool and fluid spool are disposed side by side in same passage, and structure is simple, takes up room little.
Accompanying drawing explanation
Below the content expressed by each width accompanying drawing of this manual and the mark in figure are briefly described:
Fig. 1 is the utility model valve member structural representation.
In figure: 1. inlet, 2. feed liquor spool, 3. liquid outlet, 4. location-plate, 5. control oil duct, 6. plug, 7. piston, 8. push rod, 9. one way valve.
Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, detailed description of the invention of the present utility model is described in further detail.
As shown in Figure 1, this backwash filter valve member, comprises valve body, inlet 1, liquid outlet 3, feed liquor spool 2, one way valve 9, push rod spool and establishes the control oil duct 5 on valve body and reflux mouth, wherein, valve body is hollow cylinder structure, is provided with passage vertically in valve body.
The passage end of valve body is inlet 1, the passage other end is provided with plug 6, and by the plug seal channel other end, plug can be dismantled, and is convenient to install the feed liquor spool in passage and push rod spool.
Feed liquor spool and push rod spool are located in passage side by side, and feed liquor spool and inlet are near arranging, and push rod spool and plug 6 are near arranging.
Liquid outlet establishes valve body sidepiece corresponding with feed liquor spool, and control oil duct and be connected with the push rod spool promote-side in passage, reflux mouth is between push rod spool and feed liquor spool.
The import of one way valve 9 is connected with inlet, and the outlet of one way valve is connected with control oil duct.Valve body is fixed with one way valve 9, is pilot valve, one way valve comprises handle, push rod, spring spool, and handle one end and push rod one end are hinged, and the push rod other end is corresponding with spring spool.Control the import of one way valve by handle and outlet is conducted, handle is by lever principle, and operational torque is little, operates light.
Push rod spool comprises piston 7 and push rod 8, and push rod is located at piston one end, and the piston other end in passage is connected with control oil duct.And be fixed with location-plate 4 in passage between feed liquor spool and push rod spool, on push rod, cover has helical spring, and helical spring compresses between piston and location-plate.
Feed liquor spool comprises the valve pocket be located in passage, is provided with the outer valve cylinder and interior valve cylinder that are nested together, is provided with Compress Spring in the cavity formed between outer valve cylinder and interior valve cylinder in valve pocket.In the passage of valve body, corresponding outer valve cylinder forms feed liquor valve port, and corresponding internal valve cylinder forms reflux fluid valve port.
Outer valve cylinder can slide in valve pocket, and outer valve cylinder and liquid feed valve are to corresponding, and interior valve cylinder is corresponding with push rod; Normal feed liquor, promotes outer valve cylinder by inlet feed liquor, opens feed liquor valve port, realize the path of inlet and liquid outlet; The handle of operation one way valve, fluid enters control oil duct by one way valve, again by controlling the piston end of oil duct feed liquor to push rod spool, promotion piston moves, valve cylinder in piston upper ejector pin promotes, and interior valve cylinder drives outer valve cylinder to move to inlet direction together, feed liquor valve port closes, reflux fluid valve port is opened, and liquid outlet is connected with reflux mouth, and reflux mouth is sewage backwash mouth.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that design of the present utility model and technical scheme are carried out; or design of the present utility model and technical scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
