Description
Technical field
The utility model relates to a kind of gate valves, more particularly, to a kind of inclined plate gate valve that leakproofness can be improved.
Background technique
It is often used the opening and closing of gate valve control fluid line in the industry at present.Gate valve is mainly by flashboard and valve seat group
At, valve seat shell is connected with pipeline, and inside is equipped with flashboard, flashboard and valve seat by can the mechanical structure of back and forth movement be connected.Example
Such as, one kind disclosed " gate valve " in Chinese patent literature, notification number CN206655971U, including valve seat, flashboard and
For driving the driving mechanism of flashboard closure or openness.A round mouth identical with institute's connecting pipe internal diameter is provided on flashboard, when
When round mouth matches with pipeline, access is formed in pipeline, gate valve is opened at this time；When flashboard moves, round mouth is complete with pipeline
Total detachment, the not opening place of flashboard and tube contacts, pipe path is blocked at this time, and gate valve is closed.Due to the folding of gate valve
Process is mobile by flashboard, and to guarantee leakproofness, flashboard is in close contact always with valve seat, therefore flashboard and valve in moving process
Seat thinks there is opposite sliding between two sealing surfaces of contact, scratch is also easy to produce under frictional force effect, to destroy sealing performance.
Utility model content
The utility model is to overcome the problems, such as that gate valve leakproofness easily reduces in the prior art, and providing one kind can be improved
The inclined plate gate valve of leakproofness, extends the service life of gate valve.
To achieve the goals above, the utility model uses following technical scheme:
A kind of inclined plate gate valve that leakproofness can be improved, is connected on a root canal road, including valve seat, flashboard, driving flashboard
The driving mechanism of closure or openness, the valve seat are set there are two opening, wherein place open at one end is equipped with connecting tube, another end opening
It is directly connected to the pipeline, connecting tube protrudes into valve seat, and port of the connecting tube in valve seat is equipped with scarf, the flashboard
Slant setting, flashboard sharping degree are adapted with connecting tube scarf angle, and the flashboard is connect by push rod with driving mechanism,
Pushrod movement direction is vertical with connecting tube central axes direction.Flashboard can be made to open and close in inclined plate gate valve flashboard slant setting
In journey reduce and connecting tube contact surface between friction, it is contemplated that the leakproofness of inclined plate gate valve in the off state, flashboard with
Two contact surfaces must be fitted close between connecting tube, and in moving process, opposite sliding occurs for flashboard and connecting tube, generate wiping
Wound, when flashboard slant setting, two contact surfaces do not produce relative sliding in moving process；And lateral push rod is to the axial direction of flashboard
Support force is decomposed into two axial and normal thereto power of connecting tube, and flashboard is made to cope with the pressure of connection tube fluid, protects
The leakproofness under inclined plate plate valve closing state is demonstrate,proved.
Preferably, the connection pipe end mis-cut angle is 30 degree ~ 60 degree.Inclined plate gate valve is as extraneous pipeline opening and closing
Control mechanism, need to consider axial direction size, while after inclined plate gate valve works long hours, residual can be generated in pipeline
Object, residue are attached to the surface that flashboard is in contact with connecting tube with fluids within pipes movement, destroy original smoothness, make
Leakproofness reduces when closing at flashboard, therefore flashboard is equipped with certain angle and avoids residue accumulated.Simultaneously under this organization plan,
Since flashboard is supported by push rod, and support force direction is vertical with connecting tube fluid pressure direction, thus flashboard and push rod it
Between angle it is smaller, support force decompose after vertical direction component it is smaller, cause flashboard that can not answer fluid pressure, influence to seal
Property.
Preferably, the driving mechanism includes air pressure pump, vacuum pump and solenoid directional control valve, air pressure pump, vacuum pump are in parallel
On solenoid directional control valve.Change gas circuit direction by solenoid directional control valve, control execution cylinder drive valve plate is made side-to-side movement, passed through
Push rod drives the flashboard of end to be allowed to reach folding effect with connecting tube cooperation.
Preferably, the solenoid directional control valve is connect by one section of pipeline with push rod.In view of inclined plate gate valve driving machine
Structure is located at outside valve seat, therefore push rod stroke is relatively long, be easy generate resonance during the motion, so solenoid directional control valve with
It pushing and connects a Duan Guanlu between the mechanism of ram movement, the gas in solenoid directional control valve is reached inside valve seat by pipeline, then
It pushes push rod to make it that lock be driven to make side-to-side movement to complete the opening and closing of connecting tube opening, effectively reduces the length of push rod in this way
Degree avoids too long rod-like structure and generates resonance, influences the continuous folding of inclined plate gate valve.
Preferably, the flashboard and connecting tube phase-contact surface are equipped with annular recess structure, groove is cut with pipe end is connect
Face is adapted, and bottom portion of groove is equipped with sealing ring.It is contacted between flashboard and connecting tube since the sealing effect of inclined plate gate valve relies on
The extruding in face, therefore it is equipped with groove structure in flashboard corresponding position, it is equipped with sealing ring in groove structure, in the closed state, even
Adapter tube tail end section is in groove structure, improves the sealing effect of flashboard.
Therefore, the utility model has the following beneficial effects: (1) avoids the abrasion of flashboard Yu connecting tube contact surface；(2)
Reduce accumulation of the residue on flashboard in pipeline；(3) the time required to shortening flashboard moving process.
