Abstract
The utility model discloses double valve clacks of a hydraulic control valve and belongs to a valve part. The double valve clacks of the hydraulic control valve comprises the auxiliary valve clack and the main valve clack which are arranged in the vertical direction, a valve rod is installed in the center hole of each valve clack, a sealing ring is arranged between the two valve clacks, and a sealing ring is arranged on the main valve clack and an upper opening of a valve base. The double valve clacks of the hydraulic control valve are characterized in that a conical cap is arranged on the upper portion of the auxiliary valve clack, a cylindrical fixing column is arranged on the lower portion of the auxiliary valve clack, internal threads connected with the valve rods are arranged in an inner hole, the main valve clack is in the shape of a disk, an annular boss is arranged on the upper surface of the main valve clack, a dovetail groove with the cross section in the shape of a dovetail is formed in the annular boss, the auxiliary sealing ring for sealing the auxiliary valve clack is installed in the dovetail groove, a T-shaped groove with the cross section in the shape of T is formed in the peripheral side of the bottom face of the main valve clack, the main sealing ring used for sealing the upper opening of the valve base is installed in the T-shaped groove, and a slow-closing channel hole is further formed in the main valve clack. The main sealing ring and the auxiliary ring are fixed to the upper side and the lower side of the main valve clack respectively, and compared with the prior art, the double valve clacks of the hydraulic control valve have the advantages of being simple in structure, long in service life and easy to maintain.
Description
Technical field
The utility model belongs to the flap of a kind of valve part, particularly hydraulic control valve.
Background technique
Conventionally the sealing of this kind of structure in the past adopts form that pressing plate, rubber seal, fastening piece connect as shown in Figure 2 more, because major-minor flap all needs sealing, so have two cover pressing plates, rubber seal, fastening piece, such structure component are many, loaded down with trivial details, it is large to occupy flow channel space, affect flow, and in turbulent operating mode or while vibrating large operating mode, the easy cavitation of fastening piece and become flexible, come off, the part coming off is fled arbitrarily under the impact of current, causes the damage of follow-up equipment.Major and minor flap all adopts spheroidal graphite cast iron spray epoxy technique anticorrosion, once meet with cavitation, disbonding, polluted water and impact sealing.
Model utility content
In order to overcome existing flap, need to use pressing plate and clamping bolt fixed seal ring component to occupy flow channel space large more, fastening piece easily cavitation erosion is loosening, the deficiency that working life is short, the utility model provides a kind of Double-clack of hydraulic control valve, the Double-clack of this hydraulic control valve is not only simplified structure, the amount of parts that takes in sail, and effectively reduces taking of Flow area; Guarantee sealing reliably, Sealing and fastening piece difficult drop-off, guarantee the Security of follow-up equipment.
The utility model solves the technological scheme that its technical problem adopts: a kind of Double-clack of hydraulic control valve, comprise the secondary flap and the main valve clack that are arranged above and below, in the center hole of two flaps, valve rod is housed, between two flaps, be provided with seal ring, main valve clack and the valve seat seal ring that is provided with suitable for reading, it is characterized in that: the top of described secondary flap is conical cap, bottom is cylindrical fixing column, endoporus is with the internal thread being connected with valve rod, described main valve clack is disc, its upper surface is round ring boss, round ring boss is provided with the dovetail groove that cross section is swallow-tail form, secondary seal ring with secondary flap sealing use is housed in groove, main valve clack bottom periphery is provided with the T-slot that cross section is T shape, primary seal circle with valve seat sealing use suitable for reading is housed in groove, on main valve clack, also has Slow Close runner hole.
On the described columniform fixing column of secondary flap, the set screw vertical with center hole is housed.
Described Slow Close runner hole and the angle of valve rod are 15-35 degree.
Described main valve clack, secondary flap are stainless steel and make.
Described primary seal circle adopts sulfuration process to be fixed in T-shaped groove and secondary seal ring adopts sulfuration process to be fixed in dovetail groove.
The utility model adopts respectively sulfuration process to be fixed in the T-shaped groove of bottom surface of the main valve clack that stainless steel makes and in the dovetail groove of the annular boss of upper surface primary seal circle and secondary seal ring, compared with prior art adopt pressing plate and fixing bolt fixedly have simple in structure, use reliably, on secondary flap, do not need thus fixed seal ring to adopt integrated stainless steel structure to be convenient to processing and fabricating, long service life.
