[embodiment]
Consult Fig. 1, the present invention, comprise cover 9, valve body lower cover 12, piston valve core 6, valve seat 11, pilot valve 14 and cushion collar 7 in valve upper cover 1, valve body, in described valve upper cover 1, valve body, cover 9, valve body lower cover 12 connect from top to bottom successively, overlap 9 inside in described valve body and guide sleeve 8 is installed, guide sleeve 8 is connected by floor 15 with piston valve core 6, and floor 15 radial equipartition is arranged; Be provided with spring 2 and cushion collar 7 in described piston valve core 6, spring 2 is positioned at cushion collar 7 upper end; Described pilot valve 14 is arranged on the side of valve upper cover 1, and guide sleeve 8 top is provided with piston valve core cap 3, and piston valve core cap 3 is connected with pilot valve 14 by pilot pipe 13; Be provided with water intake bottom described valve body lower cover 12, valve upper cover 1 top is provided with water outlet.
Described piston valve core 6 is in vertical state all the time in guide sleeve 8, firmly seals between piston valve core 6 and valve seat 11.Described piston valve core 6, guide sleeve 8 are all placed in valve body and overlap 9 inside.Have aperture 10 bottom described piston valve core 6, water intake is connected with pilot valve 14 by aperture 10 with water outlet.The central authorities of described piston valve core cap 3 have tapped hole, and the tapped hole of piston valve core cap 3 is provided with tubule, and piston valve core cap 3 is connected with pilot valve 14 by tubule.Be provided with pressing plate 5 in described piston valve core cap 3, pressing plate 5 is between spring 2 and cushion collar 7.Described pressing plate 5 is provided with limited cover 4, and cushion collar 7 is connected with limited cover 4.
Working procedure of the present invention:
The present invention is a kind of adapts to the pilot piston type stop valve of vertical duct in the course of the work, and guide sleeve 8 is for limiting the position of piston valve core 6; Piston valve core cap 3 upper end is sealed by valve upper cover 1 and connects pilot valve 14 by thin pipe; Pilot valve 14 can be communicated with valve body top water outlet by control piston formula spool 6, and then the motion of control piston, realizes the opening and closing of main valve.
Pilot valve 14 close time, the pressure P 2 of piston valve core inner is identical with the pressure P 1 of valve lower end water inlet, piston valve core 6 deadweight and spring 2 elastic force effect under, be pressed on valve seat 11, now main valve closedown.When opening pilot valve 14, the pressure P 2 of piston valve core inner reduces, and is equal to the pressure P 3 of valve upper end water outlet, and the pressure P 2 due to piston valve core inner is less than the pressure P 1 of valve lower end water inlet, piston valve core 6 by pressure difference jack-up, thus realizes the unlatching of main valve.Regardless of pipe angle, as long as overlap floor 15 angle on 9 in corresponding regulating valve, just can ensure that guide sleeve 8 and piston valve core 6 are in vertical position all the time, and then ensure the keying of piston valve core 6 proper motion and main valve.
The present invention, the pressure difference utilizing valve internal fluid to produce when flowing through piston valve core 6 place's aperture 10 as the power of valve opening, and passes through the lifting of the keying pilot pressure difference of pilot valve 14, and then the keying of control bound door.Be applicable to the high-pressure duct system that caliber is larger, and there is the advantage that mechanism is simple, save cost, reduce energy consumption.
Guide sleeve 8 is fixed in valve body by floor 15 structure and overlaps 9 inside, and then the parts such as valve upper cover 1, piston valve core 6, conduit are installed on guide sleeve 8.Floor 15 structure of overlapping 9 in valve body makes valve critical piece piston valve core 6, piston valve core cap 3 etc. be in pipe interior independently, by overlapping the dimensional parameters of floor 15 in change, the pose that guide sleeve 8 and piston valve core 6 overlap 9 inside in valve body can be changed, thus can be implemented in the vertical motion installed in the pipeline of different amount and all can keep piston, make full use of piston self gravitation, avoid the friction that piston valve core 6 and guide sleeve 8 are too much, improve energy-saving efficiency.
Above-described embodiment is to explanation of the present invention, is not limitation of the invention, anyly all belongs to protection scope of the present invention to the scheme after simple transformation of the present invention.
