Fig. 2 is that transverse part structure of the present invention is shown view;
Wherein 1 valve body, 2 pistons, 3 connecting rods, 4 end caps, 5 glands, 21 piston emergency valve seats, 22 emergency valve seat nuts, 23 piston valve plugs, 24 steel balls, 41 end cap valve seats, 42 end caps cushion valve rod, 43 end cap emergency valve seats, 44 plug screws, 45 springs.
The specific embodiment
For the ease of those skilled in the art's understanding, floor spring of the present invention is further specified below in conjunction with the drawings and specific embodiments:
Shown in accompanying drawing 1-2, a kind of high load-bearing floor spring comprises valve body 1, is provided with piston 2, connecting rod 3 and planker in the valve pocket of valve body successively, has the valve body end of piston 2 to be provided with end cap 4, has the valve body end of planker to be provided with gland 5; Be provided with annular oil circuit between described valve body wall and the piston 2, be provided with annular oil circuit between the valve body wall of this section valve body and the piston, this section valve body is provided with assigns the hydraulic fluid port of adjusting valve, oil pressure adjusting valve and communicating with oil circuit, also be connected with the relief valve device of forcing to protect at closing time floor spring internal construction function in external force on the described piston 2, the valve body place at described end cap 4 places is provided with the hydraulic adjustment device of 80 °～110 ° adjustable oil pressure location; Described valve body wall is provided with oil pressure adjusting valve, and described oil pressure adjusting valve is provided with 80 °～175 ° oil pressure location.Described relief valve device comprises emergency valve seat nut 21, piston valve plug 22, piston emergency valve seat 23 and steel ball 24, and emergency valve seat nut 21, piston valve plug 22 and steel ball 24 are installed on piston emergency valve seat 23 successively.Described hydraulic adjustment device comprises end cap buffering valve rod 42, end cap emergency valve seat 43, plug screw 44, the spring 45 that is located on the end cap valve seat 41.
During floor spring work, when opening the door, door-hinge drives cam, moves right by planker drivening rod and piston, and at this moment the oil on oil cylinder inner carrier the right flows into the piston left side by one way valve, realizes opening the door action.When at closing time, the rotation of cam driven door promotes left at the following piston of the effect of back-moving spring, the piston drivening rod, and connecting rod drives cam, and the rotation of cam driven door is closed door automatically.When piston is moved to the left, one way valve sealing, at the hydraulic oil on the oil cylinder inner carrier left side through adjusting needle- valve 1,2,3, flow to the right of piston along oil circuit, movement velocity is regulated adjustment valve 1,2,3 and can be obtained to close the door fast the effect of closing the door at a slow speed then by the flow-control of hydraulic oil.When door closes 80 °～175 °, close the master control valve and adjust needle-valve 1, the hydraulic fluid port that piston closes is adjusted needle- valve 2,3 can't flow out hydraulic oil, at this moment the pressure that bears of end cap emergency valve seat 1 reaches certain value, open oil pressure adjusting valve rapidly, the hydraulic oil on the oil cylinder inner carrier left side flows to the right of piston through oil pressure adjusting valve along oil circuit, obtains 80 °～175 ° orientation angles that open the door thereby regulate oil pressure adjusting valve control oil pressure.When being adjusted in the plug screw of end cap valve body, can reach 80 °～110 ° location arbitrarily.Described hydraulic adjustment device is provided with end cap valve seat, spring adjusting screw(rod), end cap buffering valve rod, end cap emergency valve seat, plug screw, hydraulic adjustment device of spring composition at the end cap valve body; Only need be adjusted in the plug screw of end cap valve body during adjusting gently.Described piston 2 built-in safety valves use external force to force at closing time, when the pressure that safety valve bears reaches certain value, open rapidly, prevent that effectively external force from forcing at closing time, and piston is impaired.So entirely spring be difficult for impaired, safe and reliable, long service life.
The above is a preferred embodiment of the present invention, and under the situation that does not break away from inventive concept of the present invention, any conspicuous distortion and the replacement carried out all belong within the protection domain of the present invention.
