Abstract
The utility model relates to a composite packing seal structure which comprises a supporting frame, non-metal gland packing, V-shaped packing, upper packing and a gland, wherein the supporting frame, the non-metal gland packing, the V-shaped packing, the upper packing and the gland are installed in sequence from bottom to top in a packing groove formed between a valve rod and a valve body, the inner side and the outer side of the non-metal gland packing are respectively sleeved with a metal sealing fin, and a spring is installed in the non-metal gland packing between the metal sealing fins inside and outside in a coaxially mode. According to the composite packing seal structure, a pressure self-sealing structure is formed with a metal and non-metal compound gland packing structure, sealing performance is reliable, working is reliable, and the service life is long. The composite packing seal structure can be applied to throttling valves, gate valves, check valves, butterfly valves, ball valves, adjusting valves and the like and can be widely used on various special occasions.
Description
Technical field
This patent belongs to valve field, relates to earthfill rockfill concrete riprap RCC, especially a kind of composite filling sealing configuration.
Background technique
Valve packing is the important sealing configuration of valve, especially in the higher occasion of high pressure, the severe spatial requirement of environment,
Model utility content
The utility model object is to overcome the deficiencies in the prior art, provide a kind of volume little, lightweight, simple composite filling sealing configuration is installed.
The purpose of this utility model is achieved in that
A kind of composite filling sealing configuration, comprise supporting frame, nonmetal stuffing box packing, V-type filler, upper filler and gland, between valve rod and valve body on valve body in made packing groove from bottom to top order be provided with supporting frame, nonmetal stuffing box packing, V-type filler, on filler and gland, it is characterized in that: be all set with a metal sealing sheet in the inside and outside both sides of nonmetal stuffing box packing, in the nonmetal stuffing box packing between the metal sealing sheet of these inside and outside both sides, be coaxially installed with a spring.
And, on the metal sealing sheet madial wall of described inner side, be embedded with uniformly at intervals multiple nonmetal seal rings, and be embedded with uniformly at intervals multiple nonmetal seal rings on the metal sealing sheet outer side wall in outside.
And support frame as described above upper center is shaped with bulge loop top and is pressed in middle part, spring lower end
And described nonmetal stuffing box packing upper end is shaped with and V-type filler lower end form fit boss, described V-type filler is coaxial tactic multiple, and upper filler contacts filler lower end surface and is shaped with the groove that coordinates V-type filling-material structure with V-type filler.
Advantage of the present utility model and good effect are:
1, the nonmetal stuffing box packing of this structure, multiple V-type filler and upper filler form nonmetal black box.
2, this structure is also provided with shape metallic leak-proof structure, adopts elastic metallic sealing to coordinate with nonmetal compound seal and strengthens sealing, when its shape metallic leak-proof structure after nonmetal stuffing box packing wearing and tearing still can keep sealing effect.
3, the utility model adopts metal and nonmetal compound seal filling-material structure mineralization pressure self sealing structure, sealability is reliable, reliable operation, long service life, can be applicable to throttle valve, gate valve, stop valve, butterfly valve, ball valve, modulating valve etc., be widely used in each distinct species occasion.
Brief description of the drawings
Fig. 1 is cross section structure sectional view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, example of the present utility model is further described; It should be noted that: the present embodiment is descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of composite filling sealing configuration, comprise supporting frame 9, nonmetal stuffing box packing 5, V-type filler 4, upper filler 3 and gland 2, between valve rod 1 and valve body 10 on valve body in made packing groove from bottom to top order be provided with supporting frame, nonmetal stuffing box packing, V-type filler, on filler and gland.
Described nonmetal stuffing box packing upper end is shaped with and V-type filler lower end form fit boss, described V-type filler is coaxial tactic multiple, upper filler contacts filler lower end surface and is shaped with the groove that coordinates V-type filling-material structure with V-type filler, this nonmetal stuffing box packing, multiple V-type filler and upper filler form nonmetal black box.
Innovative point of the present utility model is:
This sealing configuration is also provided with shape metallic leak-proof structure, all be set with a metal sealing sheet 6 in the inside and outside both sides of nonmetal stuffing box packing, in nonmetal stuffing box packing between the metal sealing sheet of these inside and outside both sides, be coaxially installed with a spring 8, this spring provides lasting pretightening force to make the tinsel of inner side be adjacent to valve rod, make the tinsel in outside be adjacent to valve seal simultaneously, this elastic metallic sealing coordinates enhancing sealing with nonmetal compound seal, when its shape metallic leak-proof structure after nonmetal stuffing box packing wearing and tearing still can keep sealing effect.
The metal sealing sheet that the elastic force of spring is delivered to inside and outside both sides by nonmetal stuffing box packing reaches sealing effect.
In order to strengthen sealing effect, on the metal sealing sheet madial wall of described inner side, be embedded with uniformly at intervals multiple nonmetal seal rings 7, and be embedded with uniformly at intervals multiple nonmetal seal rings on the metal sealing sheet outer side wall in outside.
Support frame as described above upper center is shaped with bulge loop top and is pressed in middle part, spring lower end, and manual tune compresses gland, and gland regulates the packing seal structure that compresses below, carries out auxiliary seal.
