Description
Technical field
The utility model belongs to valve field, specifically about a kind of regulating valve.The utility model is suitable for two-way
The flow regulating and controlling valve in circulation medium channel.
Background technique
There are many structure type of flow control valve, and shut-off valve is the flow control valve of commonplace use, and structure is by valve
Body, valve seat, flap, valve deck, valve rod, transmission mechanism, sealing element and mounting rack composition control flap by operating transmission mechanism
Aperture between valve seat realizes the adjusting to pipeline medium flow.Its major defect is that structure is more complex, and flow adjusts sensitive
Spend it is low, in operating process sealing element exist abrasion, be easy to happen leakage, product service life is short.
Summary of the invention
The purpose of this utility model is to provide that a kind of structure is simple, adjusts sensitivity for disadvantage of the existing technology
Flow regulator high, sealing reliability is good, the service life is long.
The technical solution of the utility model includes valve body, flap, adjusting rod, and valve body import runner and outlet flow are mutually hung down
Directly；Using cone made of rubber material, the lower end cone face of the cone is located at valve body import runner and goes out mainly flap
Mouth runner junction, circular cone center line are overlapped with valve body import runner center line, and cone upper end connects annular rubber plane,
The ring-shaped rubber plane is mounted in valve body by stud compression；Center stud is formed with screw hole, and adjusting rod is installed on institute using screw thread
It states in screw hole, adjusting rod lower end has the mutually matched hemisphere of concave spherical surface with cone upper surface center, adjusting rod upper end
With regulating tank.
Preferably, water-drop-shaped cavity is formed in cone, it is recessed with cone upper surface center on the left of water-drop-shaped cavity
Through-hole is formed between on the left of spherical surface.
The utility model has the advantages that adjusting rubber flap cone in valve body import runner and outlet stream using adjusting rod
Position in road realizes that flow is adjusted, and structure is simple, adjusting is sensitive, sealing reliability is good, long service life.
Detailed description of the invention
Fig. 1 is the utility model structure diagram.
Fig. 2 is structural schematic diagram when the utility model medium flows into flap from outlet flow.
Fig. 3 is structural schematic diagram when the utility model medium flows into flap from inlet channel.
Specific embodiment
Flow regulator as shown in Figure 1, including valve body 6, flap 1, adjusting rod 5,6 inlet channel 7 of valve body and outlet stream
Road 8 is mutually perpendicular to, i.e. the two channel centerline is mutually perpendicular to；Flap 1 uses cone made of rubber material, the cone
Lower end cone face is located in the channel of 6 inlet channel 7 of valve body and 8 junction of outlet flow, circular cone center line and 6 inlet flow of valve body
Road center line is overlapped, and cone upper end connects annular rubber plane, which is mounted on valve body 6 by the compression of stud 4
It is interior, the sealing of flap 1 is fixed in valve body 6, is connected with each other between the mounting hole on stud 4 and valve body 6 using screw thread；Stud 4
Center is formed with screw hole, and adjusting rod 5 is installed in the screw hole using screw thread, 5 lower end of adjusting rod have in cone upper surface
The mutually matched hemisphere of the concave spherical surface of the heart, 5 upper end of adjusting rod have regulating tank, by adjusting adjusting rod 5 in 4 center spiral shell of stud
Position in hole realizes that the relative position to 1 lower cone body of flap in 6 inlet channel 7 of valve body and outlet flow 8 adjusts,
Flow is driven to adjust, structure is simple, and adjusting sensitivity is good, meanwhile, product seal point all realizes static seal and rubber material
Elastic property, keep the sealing performance of this product reliable, long service life.
Water-drop-shaped cavity 2 is formed in the cone of flap 1, the water-drop-shaped cavity 2 refers to that the shape of the cavity is upper end
The big small conical bores in lower end, on the left of the concave spherical surface at 2 left side of water-drop-shaped cavity and cone upper surface center between be formed with
Through-hole 3, the through-hole 3 are in communication with the outside by the gap between adjusting rod 5 and stud 4.When medium is from the inlet channel 7 of valve body 6
When flowing to flap 1, pressure medium pushes the cone of 1 lower part of flap to the left, so that flow of media flow reduces, such as Fig. 3
It is shown.When medium flows to flap 1 from the outlet flow 8 of valve body 6, pressure medium pushes away the cone of 1 lower part of flap to the right
Pressure, so that flow of media flow increases, as shown in Figure 2.It realizes forward and reverse difference flow to automatically control, meets hydraulic piston
Control mechanism, valve valve seat hydraulic cavities etc. at a slow speed pressurising, quick pressure releasing requirement.
