Domain includes ship to shore unloading, highway, railway groove tank handling and other fix and move fluid reservoir, such as oil filling riser,
Connection between fluid delivery arm and transport agent.
Urgent release systems are in peculiar to vessel and land with the security in farthest ensure that fluid conveying in oil filling riser.Pass through
One simple and unique design, when oil filling riser has exceeded the rated capacity of operating system, this system can entirely certainly in oil filling riser
Dynamic safely disconnects and without any leakage.Its advantage ensure when being dangerous occur triggering, moment closure valve, few water clock and
The relatively small pressure loss.Break mechanism should ensure to enable a device to when " ejection escape " it is automatic, be rapidly separated；Ensure again
There is " phase buffer " before disengaging, avoid " disengaging " occur during routine operation, influence normal handling operation.
At present, existing urgent Pull breaking ualve is a kind of quick with one kind on the combustible and explosive articles such as oil product, natural gas
Pull breaking ualve, but it is high if applied in the hygienic requirements such as the strong corrosive medias such as liquid chlorine, strong acid, highly basic and food, medicine
Industry can not just meet requirement, and first, the strong corrosive media such as liquid chlorine, strong acid, highly basic is easily to the gold of urgent Pull breaking ualve
Belong to material corrosion, cause urgent Pull breaking ualve service life to greatly shorten, although those skilled in the art will know that polytetrafluoroethylene (PTFE) can
To solve etching problem, polytetrafluoroethylene (PTFE) can be used for solving the problems, such as corrosion by those skilled in the art, but in technical pattern
There are blind area, can not overcome the problem of urgent Pull breaking ualve is with polytetrafluoroethylene (PTFE) structure fusion.
The content of the invention
The present invention can not be used in severe corrosives such as liquid chlorine, strong acid, highly basic to solve above-mentioned existing urgent Pull breaking ualve
The problem of hygienic requirements such as medium and food, medicine high industry, specially design a kind of urgent Pull breaking ualve of Fluorine-lined.
To achieve these goals, the technical solution adopted by the present invention is as follows：
A kind of urgent Pull breaking ualve of Fluorine-lined, including housing, flap and valve seat, it is characterised in that：The flap is sleeved in housing, valve
Valve connection corresponding with valve seat；The gudgeon of upper flap and lower Disc uses the structure that negative and positive coordinate, and the valve seat uses Combined valve
Seat, the valve seat are equipped with primary seal；
The housing uses echelon contraction structure, and case bushing is equipped with the housing；
The flap uses shunting structure, and the head of flap forms for the cylinder of gyroscope-like and afterbody, is equipped with gyroscope-like
Fluid hole, gyroscope-like are connected with cylinder；Spring is cased with outside cylinder；
The valve seat outer ring is metal material, and metal material embedded valve seat bushing, the valve seat bush inner wall is cambered surface and and valve
The gyro outer wall of valve, which corresponds to, to coincide.
Further, the primary seal uses triple seal structure, the primary seal be divided into primary seal, secondary seal with
And three-level sealing.
Further, the case bushing and valve seat bush use fluorine glue or polytetrafluoroethylene material.
Further, the housing, which is externally provided with, breaks structure and clamp system.
Further, the echelon contraction structure of the housing is correspondingly arranged with valve flap structure.
Further, the fluid hole in the gyroscope-like is connected with cylinder.
Further, the housing uses metal material, and the both ends of housing are equipped with flange pad assembly.
The invention has the advantages that：
Inventive shell using the material such as metal inner lining fluorine glue or polytetrafluoroethylene (PTFE), internal materials all using polytetrafluoroethylene (PTFE) or
Metal is coated；To adapt to the inner lining structure of housing, flap creativeness uses shunting structure, not only can guarantee that normal discharge, but also
Effectively sealed after can ensure that disengaging.The Pull breaking ualve unique structure, principle are novel, are to the effective of traditional Pull breaking ualve using effective
Break through and innovate.

Embodiment
The present invention is described further below in conjunction with the accompanying drawings：
As shown in Fig. 1,2,3,4 and 5, a kind of urgent Pull breaking ualve of Fluorine-lined, including housing 1, flap 2 and valve seat 3, its feature exist
In：The flap 2 is sleeved in housing 1, the connection corresponding with valve seat 3 of flap 2；The gudgeon of upper flap and lower Disc is coordinated using negative and positive
Structure, the valve seat 3 uses combined valve seat, and the valve seat 3 is equipped with primary seal 4；
The housing 1 uses echelon contraction structure, and case bushing 9 is equipped with the housing 1；
The flap 2 uses shunting structure, and the head of flap 2 forms for the cylinder of gyroscope-like and afterbody, set in gyroscope-like
There is fluid hole 10, gyroscope-like is connected with cylinder；Spring 6 is cased with outside cylinder；
3 outer ring of valve seat is metal material, metal material embedded valve seat bushing 11,11 inner wall of valve seat bush for cambered surface and
It is corresponding with the gyro outer wall of flap 2 to coincide.
The primary seal 4 uses triple seal structure, the primary seal 4 divide for primary seal 41, secondary seal 42 and
Three-level sealing 43.The case bushing 9 and valve seat bush 11 use fluorine glue or polytetrafluoroethylene material.The housing 1 is externally provided with

Embodiment：
As shown in Figure 1, the structure that housing 1 is shunk using echelon, easy to the design and assembling of case bushing 9；And traditional Pull breaking ualve
Inner cavity is V-structure, can not realize tetrafluoro bushing, is coincide even rubber bushing also is difficult to realize.
As shown in Figures 2 and 3, flap 2 is oriented to outer wall using the structure of interior reduction of fractions to a common denominator stream, is solved tradition well and broken
Barrier problem of the valve centre pilot valve rod support base to bushing, this is key breakthrough of the Pull breaking ualve to structural principle, makes bushing
Realize that the barrier to medium and housing is simple and easy.
As shown in figure 5,3 material of valve seat, based on tetrafluoro, outer engaged column, easy to implement can seal and have
Enough compression strength.
As shown in figure 4, primary seal 4 uses triple seal structure, it is ensured that Pull breaking ualve binding site sealed reliable, primary seal
For sealing metal material valve seat and valve seat bush 11, secondary seal is used to seal lower valve base, and the three-level sealing is used for close
Seal valve seat and housing 1.
The both ends of housing 1 are equipped with flange pad assembly 7, and housing 1 is lined with fluorine glue or polytetrafluoroethylene material, and flap 2, which divides, is
Upper flap and lower Disc, upper flap is respectively placed in housing 1 above and below with lower Disc, on the cylinder of upper flap and lower Disc
It is cased with spring 6, the gudgeon of the upper flap and lower Disc uses the gyro of the structure that negative and positive coordinate, the upper flap and lower Disc
Structure is equipped with fluid hole 10, and upper flap is placed on combined valve seat with lower Disc, by the outer wall of the gyroscope structure of flap with
The inner wall of valve seat corresponds to connection, and when Pull breaking ualve turns on, i.e., the outer wall of the gyroscope structure of flap with the inner wall of valve seat is separated,
The strong corrosive medias such as liquid chlorine, strong acid, highly basic are along cylinder, and the fluid hole 10 on gyroscope structure circulates, when Pull breaking ualve is not led
When logical, i.e., the outer wall of the gyroscope structure of flap is close to the inner wall of valve seat, and the strong corrosive media such as liquid chlorine, strong acid, highly basic can not
Circulation.Realized whether Pull breaking ualve turns on by breaking mechanism and spring.
The above description is merely a specific embodiment, but the protection domain invented is not limited thereto, any ripe
