Abstract
The utility model discloses a novel stop valve which comprises a valve body and a valve clack; the valve body is internally provided with a movably arranged cross support; two sides of the support are respectively connected with one ends of connecting rods by connecting elements, and the other ends of the connecting rods are respectively connectd with a semispherical valve clack; the upper end of the support is provided with a guider connected with a valve rod; the upper end and the lower end of the valve clack are respectively in contact with the inner edge of a valve body through port, so as to form a seal surface; the valve body is provided with a water charge and discharge pipe communicated with the inner part of the valve body; the inner edge of the valve body through port is provided with a seal grease groove; a plurality of grease adding cups are uniformly distributed on the circumference of the upper surface of the valve body; and each grease adding cup is communicated with the seal groove. The stop valve disclosed by the utility model is simple in structure; because seal grease is added between the valve body and the valve clack, the abrasion of the valve clack in the rotation process is reduced; the seal effect is improved; the service life of the valve is prolonged; and water is filled in the valve body when the valve is closed, not only can the seal effect of the seal surface be improved, but also one part of residual toxic gases can be decomposed effectively, and the environment pollution is reduced.
Description
Technical field
The utility model relates to a kind of pipeline valve, particularly the novel cut-off valve on a kind of pipeline that is applicable to the circulation of various toxic gases.
Background technique
Valve is a kind of piping element of controlling fluid motion, generally comprise three kinds of ball valves, gate valve, butterfly valve, this valve is large due to moment of torsion, sealing surface wear is large, and after certain time limit, the sealing surface wear between flap and valve is serious, especially the corrosive pipeline of toxic gas circulation is serious, in case sealing surface is worn, can have a strong impact on its sealability, serious meeting causes gas leak, not only befouling environment, and entail dangers to staff's life safety.
The model utility content
The utility model is for the defective that is applied in now valve sealing face damage easy to wear on the toxic gas pipeline, and a kind of novel cut-off valve of good sealing effect is provided.
Realize that above-mentioned purpose by the following technical solutions: a kind of novel cut-off valve, comprise valve body and flap, valve body is made of with the valve body port that is connected with piping flange the spherical hollow space of integrative-structure, valve inner is equipped with the movable cross bracket that arranges, the support both sides are connected with connecting rod one end with link respectively, and the connecting rod the other end is connected with half globe disk respectively; The support upper end is provided with guider, and this guider is connected with valve rod; The two ends up and down of described flap touch with the inward flange of valve body port respectively, consist of sealing surface, are provided with the intake-discharge pipe with its internal communication on described valve body; Be provided with the seal gease groove on the inward flange of described valve body port; Described valve body upper surface be evenly distributed in a plurality of stuffing cups, each stuffing cup is communicated with the seal gease groove.
Compared with prior art, this novel disclosed this cut-off valve, simple in structure, due to the seal gease that adds between valve body and flap, reduced the wearing and tearing in the flap rotation process, improve sealing effect, extend the working life of valve; Fill with water during valve closing in valve body, can not only improve the sealing effect of sealing surface, can also effectively decompose the remaining toxic gas of a part, environmental contamination reduction.
As preferred version: is provided with a plurality of seal gease passages along its circumference in the valve body port, the two ends of seal gease passage are communicated with stuffing cup and seal gease groove respectively.
The inward flange of valve body port and seal gease groove all fit tightly with the flap side.
The seal gease groove is arranged on the circumference of valve body port inward flange.
During valve closing, valve inner is filled with water by intake-discharge pipe; Valve body is discharged the water in valve body by intake-discharge pipe before opening.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is partial enlarged drawing of the present utility model.
In figure: guider 1, valve body port 2, support 3, connecting rod 4, flap 5, valve body 6, intake-discharge pipe 7, stuffing cup 8, seal gease passage 9, seal gease groove 10.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
Referring to accompanying drawing 1-2, this a kind of Novel cutting valve that breaks comprises valve body 6 and flap 5, and valve body 6 is made of with the valve body port 2 that is connected with piping flange the spherical hollow space of integrative-structure.Rotating support 3 is equipped with in valve body 6 inside, and support 3 both sides are connected with an end of connecting rod 4 by bolt respectively, and in the present embodiment, the both sides of support 3 are connected with respectively two connecting rods, and the connecting rod the other end is connected with half globe disk 5 respectively.Support 3 upper ends are provided with guider 1, and this guider 1 is connected with valve rod, and rotation valve rod, guider drive support and rotate, thereby realize that flap rotates.The two ends up and down of flap 5 touch with the inward flange of valve body port 2 respectively, consist of sealing surface.Be provided with the intake-discharge pipe 7 with its internal communication on valve body, be provided with the valve of controlling water inlet and draining on intake-discharge pipe 7, and the cross current of intake-discharge pipe and outside.
Be provided with seal gease groove 10 on the inward flange of valve body port 2, the inward flange of valve body port 2 and seal gease groove 10 all fit tightly with flap 5 sides.The valve body upper surface be evenly distributed in a plurality of stuffing cups 8, each stuffing cup 8 is communicated with seal gease groove 10.Be preferably: valve body port 2 is interior is provided with a plurality of seal gease passages 9 along its circumference, and the two ends of seal gease passage 9 are communicated with stuffing cup 8 and seal gease groove 10 respectively.
During this was novel: the seal gease in the seal gease groove consisted of seal ring, and this is one sealing; Seal gease groove both sides are respectively two closely special faces, are sealing surface, and this is two road sealings; Filling with water in valve body is exactly water-stop, and this is three seals.
During this valve closing, valve inner is filled with water by intake-discharge pipe, not only can improve the sealing effect of sealing surface, and can increase the mechanical property of flap; Before valve body is opened, by intake-discharge pipe, the water in valve body is discharged.
Working principle: when closing: valve rod clockwise rotates, and guider drives support and rotates, and when namely flap clockwise rotated the valve seal balance, connecting rod acted on up and down and makes flap protruding, (is this effect up and down conventional sealing technique?) throttle down; During unlatching, valve rod rotates counterclockwise, and drivening rod moves up and down to be wanted to inside contract, and after sealing separately, guider continues to drive support and flap rotation 90 degree make, valve open.
