Abstract
The utility model provides a kind of small-sized sealing gate valve, comprising: valve body, the valve body low-speed WEDM；Seal groove is opened on sealing plate, the sealing plate two sides, and the sealing plate is oriented to by bearing, so that sealing plate be avoided to swing, the bearing slides to realize the process on and off of the sealing plug-in board valve in the seal groove；And driving mechanism, for driving the sealing plate, valve body roughness is 0.8, and bearing is deep groove ball bearing, and seal groove is U-type groove, and driving mechanism is Manual drive mechanism, including handwheel and the lead screw driven by the handwheel.Valve mechanism is simple, and valve body directly uses a sealing plate to realize the structure of sealing, simplifies the quantity of inner body, small in size, is easily installed and uses.
Description
Technical field
The utility model relates to machinery field, especially a kind of small capacity double sealing plug-in board valve.
Background technique
Gate valve is also known as manual knife-shape gate valve, thorough with small in size, flow resistance is small, light-weight, easy to install, quick detachable advantage
Bottom solves the problems, such as that common valve flow resistance is big, weight is big, installation is difficult, takes up a large area, its working principle is that a kind of flashboard with
Valve seat is in close contact the valve of sealing always, and the round mouth of a latus rectum size is provided on valve plate, is opened and closed by flashboard so that flashboard
The advantages of movement that upper round mouth is completely disengaged and matched with latus rectum, valve, is valve body latus rectum un-grooved, and medium will not block
Resistance blocking, and there are full-bore flow characteristics, sealing structure can be divided into soft seal, hard sealing structure.However it is inserted in the past
In plate valve structure, although small-sized gate valve shape is small, internal structure and large size valve are a little more many than part, and single sealing plate is such as
This, double density sealing plate is more complicated.
Utility model content
In order to overcome the problems, such as structure of the existing technology, the utility model provides that a kind of part is few and structure is simple
Small-sized sealing gate valve.
The purpose of this utility model is to provide a kind of small-sized sealing gate valves, comprising:
Valve body, the valve body low-speed WEDM；
Seal groove is opened on sealing plate, the sealing plate two sides, and the sealing plate is oriented to by bearing, to avoid sealing plate left
Right swing, the bearing slide to realize the process on and off of the sealing plug-in board valve in the seal groove；With
And
Driving mechanism, for driving the sealing plate.
Preferably, the valve body roughness is 0.8.
Preferably, the bearing is deep groove ball bearing.
Preferably, the seal groove is U-type groove.
Preferably, the driving mechanism is Manual drive mechanism, including handwheel and the silk driven by the handwheel
Thick stick.
This unconventional small-sized sealing gate valve, valve mechanism is simple, and valve body directly uses a sealing plate to realize sealing
Structure, simplify the quantity of inner body, it is small in size, be easily installed and use.
According to the accompanying drawings to the detailed description of the utility model specific embodiment, those skilled in the art will be more
Add the above-mentioned and other purposes, advantages and features of clear the utility model.
Detailed description of the invention
Some specific realities of the utility model are described in detail by way of example and not limitation with reference to the accompanying drawings hereinafter
Apply example.Identical appended drawing reference denotes same or similar part or part in attached drawing.It should be appreciated by those skilled in the art that
The drawings are not necessarily drawn to scale.The target and feature of the utility model will more in view of following description taken together with the accompanying drawings
Add obviously, in attached drawing:
Attached drawing 1 is the front view and side when being in close state according to the small-sized sealing gate valve of the utility model embodiment
View；
Attached drawing 2 is according to the small-sized sealing gate valve of the utility model embodiment front view in the open state and side
View.
Specific embodiment
Specific embodiment of the present utility model is described in detail with reference to the accompanying drawing, but is not intended to limit this reality
With novel protection scope.
Referring to the front view that attached drawing 1 is when being in close state according to the small-sized sealing gate valve of the utility model embodiment
And side view；And attached drawing 2 is facing in the open state according to the small-sized sealing gate valve of the utility model embodiment
Figure and side view.
As shown, the small-sized sealing gate valve of the utility model may include handwheel 10, lead screw 20, sealing plate 30, axis
Hold 40, valve body 50, promoting menstruation 80 and the seal groove 60 and round mouth 70 being formed on sealing plate 30.
The present embodiment valve mechanism is simple, and driving mechanism drives plate sealing together, and seal groove is opened on sealing plate two sides, and valve body is slow
Wire wire cutting, roughness is up to 0.8, when sealing plate moves to valve location, realizes sealing.Sealing plate is during the motion
Be oriented to by one group of deep groove ball bearing, so that sealing plate will not swing, be provided with U-lag on sealing plate, valve opening and
In turn off process, deep-groove ball axis slide-and-guide in U-lag, valve body directly uses a sealing plate to realize the structure sealed.The valve
Door driving method be it is manual, the movement of sealing plate 30 is driven by the drive lead screw 20 of handwheel 10.Certain those skilled in the art
It is understood that other driving methods are also within the protection scope of the present utility model.
This unconventional small-sized sealing gate valve example, valve mechanism is simple, and valve body directly uses a sealing plate to realize
The structure of sealing simplifies the quantity of inner body, small in size, is easily installed and uses.
Technical solution provided by the utility model embodiment is described in detail above, it is used herein specifically
A example is expounded the principle and embodiment of the utility model embodiment, and the explanation of above embodiments is only applicable to help
Assistant solves the principle of the utility model embodiment；Those of ordinary skill in the art simultaneously, embodiment according to the present utility model,
There will be changes in terms of specific embodiments and scope of application, in conclusion the content of the present specification should not be construed as pair
The limitation of the utility model.
