Abstract
The utility model relates to a kind of sealed valve, comprise valve body, fixed cover, valve handle and valve rod, described valve inner is provided with liquid outlet channel, the lower end of described valve rod is provided with support block, described support block is positioned at lift lug, described lift lug is connected with connecting rod, and the both sides of described connecting rod are connected with cover plate, and the lower end of described valve body is provided with the guiding groove adapted with cover plate.The utility model is cover plate structure by arranging due to what adopt, such cover plate carries out the movement of vertical direction under the effect of valve rod, when open and close, can not rotate, the friction between cover plate and valve inner can be reduced, extend the working life of valve.
Description
Technical field
The utility model relates to field of mechanical technique, particularly relates to a kind of sealed valve.
Background technique
Equipment, refers to supply people's Long-Time Service aborning, and substantially in Reusability keeps original physical form and the means of production of function and the general name of material goods.The equipment facility equipment aggregate that normally a group is medium-and-large-sized, all cannot take operation and must have fixing pedestal, uses power supply and so on power to operate and impersonal force.
Generally speaking equipment be all placed on exclusive room such as machine room, workshop, factory building, because noise or waste gas can be produced during running, all except invisible information except information equipment is input output, the material that much equipment wants input output tangible, so more need the ability smooth operation of custom-designed place.The kind of equipment and spare part is a lot, for the ease of management and supply, general by following classification.1. part classification is divided; 2. part source divides; 3. part operating characteristic is divided; Standing: refer to often to use, the large and single AUTOMATIC PACKING MACHINE valency of equipment idle cost is lower, the part that needs often to keep certain storage level; 4. spare part precision and manufacture complexity are divided; Key component: refer to the part that precision is high, manufacture difficulty plays a crucial role greatly, in a device.General part: refer to other mechanical spare part except key component.
Valve is the controlling component in fluid delivery system, there is cut-off, adjustment, water conservancy diversion, prevent the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief, very little moment of rotation is needed during operated valve, its compact structure, be easy to Operation and maintenance, be suitable for directly doing opening and closing to use, extensive use in engineering, existing valve mechanism, the use of ball valve is the most extensive, because close contact forms hard sealing between the valve seat of ball valve and spool, in very strong friction, relative movement occurs between them, there is loss in friction, also makes valve switch not be very flexible.Therefore, for solving the problem, spy provides a kind of new technological scheme.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of sealed valve.
The utility model is achieved through the following technical solutions:
A kind of sealed valve, comprise valve body, fixed cover, valve handle and valve rod, described valve inner is provided with liquid outlet channel, the lower end of described valve rod is provided with support block, described support block is positioned at lift lug, described lift lug is connected with connecting rod, and the both sides of described connecting rod are connected with cover plate, and the lower end of described valve body is provided with the guiding groove adapted with cover plate.
As optimal technical scheme of the present utility model, between described cover plate and valve body, be provided with sealing layer.
As optimal technical scheme of the present utility model, the diameter of described support block is greater than the diameter of valve rod.
As optimal technical scheme of the present utility model, for being arranged vertically between described connecting rod and cover plate.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, the utility model is cover plate structure by arranging due to what adopt, such cover plate carries out the movement of vertical direction under the effect of valve rod, when open and close, can not rotate, the friction between cover plate and valve inner can be reduced, extend the working life of valve.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. valve body; 101. liquid outlet channel; 102. guiding groove; 2. fixed cover; 3. valve handle; 4. valve rod; 5. support block; 6. lift lug; 7. connecting rod; 8. cover plate; 9. sealing layer.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
A kind of sealed valve, comprise valve body 1, fixed cover 2, valve handle 3 and valve rod 4, described valve body 1 inside is provided with liquid outlet channel 101, and the lower end of described valve rod 4 is provided with support block 5, the diameter of wherein said support block 5 is greater than the diameter of valve rod 4, can play the effect of lifting like this to lift lug 6.Described support block 5 is positioned at lift lug 6, described lift lug 6 is connected with connecting rod 7, the both sides of described connecting rod 7 are connected with cover plate 8, and for being arranged vertically between described connecting rod 7 and cover plate 8, sealing layer 9 is provided with between wherein said cover plate 8 and valve body 1, the lower end of described valve body 1 is provided with the guiding groove 102 adapted with cover plate 8, and such cover plate 8 is positioned at guiding groove 102 in lower end when sealing.By employing is cover plate 8 structure, and such cover plate 8 carries out the movement of vertical direction under the effect of valve rod 4, when open and close, can not rotate, can reduce the friction between cover plate 8 and valve body 1 inside, extends the working life of valve.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
