Line is parallel or is installed on upper valve body in the vertical mode of inlet axis and outlet axes.
By adopting the above technical scheme, perfect structure design, has the function of shut-off valve, check-valves, three kinds of water-hammer arrester,
When completely closing, realizes break-in facility, used as shut-off valve；When flap and valve seat have certain aperture, existed by valve rod
Sliding and the effect of reset spring, may be implemented the function of noise elimination non-return and water hammer-resistant on guide rod；In addition, lower valve body can be with
According to pipeline situation, the setting angle between lower valve body and upper valve body is adjusted, wide adaptation range can adapt in straight trip or right angle
In pipeline, save the cost facilitates installation.
The further setting of the utility model: the valve body periphery of handwheel one end is arranged with the indicating sleeve with graduation mark, institute
Stating handwheel and being connected has housing to form cooperation in the instruction cover of indicating sleeve periphery, the indicating sleeve and instruction cover to observe flap
With the aperture of valve seat.
Guide rod can be made to go up and down by rotation hand wheel using above-mentioned further setting, to adjust flap and valve seat
Aperture is realized and adjusts flow effect, can be used as the use of quiescent flow balanced valve.
The further setting of the utility model: having the sliding eye for valve stem slides on guide rod, the sliding eye
The through-hole being provided on inner wall inside and outside connection sliding eye.
Further it is arranged using above-mentioned, the air or minute impurities that through-hole is used to be discharged in sliding eye ensure that medium
Middle air and molecule, which enter, impacts opening and closing.
The further setting again of the utility model: it is slidably connected between guide rod and valve rod by sliding bearing.
Using above-mentioned setting further again, convenient for the sliding between guide rod and valve rod.
The further setting again of the utility model: valve seat is installed at the lower valve body of upper valve body.
It is not only more convenient when installing valve seat using above-mentioned setting further again, and valve seat easy to disassemble carries out
Maintenance and repair.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model specific embodiment；
Fig. 2 is structural schematic diagram when the utility model is mounted on right angle pipeline；
Fig. 3 is the partial enlarged view in the utility model Fig. 2 at A；
Wherein, handwheel 1, valve rod 2, valve seat 3, flap 4, guide rod 5, valve body 6, import 61, outlet 62, reset spring 7, on
Valve body 63, lower valve body 64, indicating sleeve 65, instruction cover 11, sliding eye 51, through-hole 52, sliding bearing 53.
Specific embodiment
A kind of multifunctional water pump control valve as shown in FIG. 1 to FIG. 3 includes handwheel 11, valve rod 22, valve seat 33, flap
44, guide rod 55 and the valve body 66 with import 61 and outlet 62, valve rod 2 are fixedly connected with flap 4, flap 4 and 3 shape of valve seat
Cooperate at sealing, guide rod 5 and handwheel 1 are connected, and rotation hand wheel 1, guide rod 5 accordingly rises or falls, one end of valve rod 2
It is coaxially arranged in guide rod 5 and is slidably matched with guide rod 5,5 periphery of guide rod is additionally provided with reset spring 7, resets bullet
7 both ends of spring are against in flap 4 and valve body 6 respectively on cavity wall.Valve body 6 be set as with outlet 62 upper valve body 63 and have into
The split type structure of the lower valve body 64 of mouth 61, upper valve body 63 are detachably connected with lower valve body 64 by bolt part, in straight trip pipeline
When installation, lower valve body 64 is installed on upper valve body 63 in 61 axis of the import mode parallel with 62 axis of outlet, realizes straight trip peace
Dress；In vertical pipe installation, lower valve body 64 is installed on upper valve body 63 in 61 axis of the import mode vertical with 62 axis of outlet
On, elbow bend is substituted, realizes and is mounted in pipeline without the right angle in the case where elbow bend.Rotation hand wheel 1 drives guiding
