Abstract
The utility model provides a kind of valve flashboard sealing structure, including valve, flashboard is connected in the valve, the flashboard shape is matched with the vertical section shape of valve flashboard junction position, the both sides of the valve connection flashboard are equipped with the ring-shaped baffle of limitation ram movement, the flashboard both sides are equipped with cyclic annular dovetail groove, the O-ring seals with ring dress dove tail shape cooperation are connected in the ring-type dovetail groove, the O-ring seals are soft material.The utility model can simplify technique while the sealing structure for ensureing that tightness and the utility model use is ensureing product quality, reduce cost, improve processing efficiency.
Description
Technical field
The utility model is related to valve fittings design field, specifically, being to be related to a kind of valve flashboard sealing knot
Structure.
Background technology
After flashboard processing, compression copper sealing plate needs are secondary to be clamped, processes, and the depth of parallelism is not easy to control and labor intensity
Greatly, processing efficiency is low, and sealing intensity is poor, high rejection rate.In addition, gate board sealing also has the encapsulated sealing means of flashboard, still
The encapsulated process of flashboard is more, of high cost.
Utility model content
The purpose of the utility model is to overcome the shortcomings of above-mentioned traditional technology, provide a kind of valve flashboard sealing knot
Structure can ensure to simplify technique while product quality, reduce cost, improve processing efficiency.
The purpose of this utility model is reached by following technical measures：A kind of valve flashboard sealing structure, including
Valve, it is characterised in that：Flashboard, the flashboard shape and the vertical section of valve flashboard junction position are connected in the valve
Shape matches, and the both sides of the valve connection flashboard are equipped with the ring-shaped baffle of limitation ram movement, and the flashboard both sides are equipped with
Cyclic annular dovetail groove is connected with the O-ring seals with ring dress dove tail shape cooperation, O shapes sealing in the ring-type dovetail groove
It encloses as soft material.
A kind of optimal technical scheme is fixedly connected with nut in the flashboard, and the nut is connected with matches with nut thread
The leading screw of conjunction, the leading screw lower part are located in flashboard body, and the leading screw top is exposed outside in flashboard.
A kind of optimal technical scheme, the part that the leading screw is located on the outside of flashboard, which is connected with, screws handle.
A kind of optimal technical scheme, the O-ring seals are rubber material.
A kind of optimal technical scheme, the O-ring seals are hinged in ring dress dovetail groove.
Using the additional screw device of leading screw for open and close flashboard, turn leading screw is made by the nut being fixed in flashboard
Obtaining flashboard can move up and down, and O-ring seals, big external small, the O-ring seals in oat tail groove structure inside are connected in oat tail groove structure
Being put into wherein can preferably be connected on flashboard, when flashboard moves up and down, O-ring seals is driven to move together, will not make O shapes
Sealing ring is fallen, and between flashboard and the ring-shaped baffle of valve body, the two closely connects O-ring seals, and liquid will not therefrom flow
Go out, there is good leakproofness, to prevent O-ring seals from falling, O-ring seals are with changing the splicing of shape dovetail groove, under double action, O
Shape sealing ring is not fallen out more.
By adopting the above-described technical solution, compared with prior art, the utility model has the advantages that：
Product structure is improved to soft seal, in moment of torsion in the case of, the sealing of dot encapsulation specific surface more can guarantee sealing
The sealing structure that degree and the utility model use simplifies technique while product quality is ensured, reduces cost, improves
Processing efficiency.
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Description of the drawings
Attached drawing 1 is a kind of structure diagram of valve flashboard sealing structure of the utility model.
Wherein, 1- valves, 2- flashboards, 3- ring-shaped baffles, 4- ring-type dovetail grooves, 5-O shape sealing rings, 6- nuts, 7- leading screws,
8- screws handle.
Specific embodiment
Embodiment：As shown in Figure 1, a kind of 1 ram seal structure of valve, including valve 1, is connected in the valve 1
Flashboard, the flashboard shape are matched with the vertical section shape of 1 flashboard junction position of valve, and the valve 1 connects flashboard
Both sides are equipped with the ring-shaped baffle 3 of limitation ram movement, and the flashboard both sides are equipped with cyclic annular dovetail groove 4, in the ring-type dovetail groove 4
The O-ring seals 5 with ring dress dove tail shape cooperation are connected with, the O-ring seals 5 are soft material.
The ring-shaped baffle 3 is to be integrally machined with valve body, and the ring dress gear with limitation ram movement is equipped in valve body
Harden structure, it is described to change shape baffle arrangement and 5 Interaction enhanced leakproofness of O-ring seals.
4 structure of cyclic annular dovetail groove of 2 both sides of flashboard is on 2 body of flashboard by being processed into or welding with ring dress
The workpiece of dovetail groove is made.
Nut 6 is fixedly connected in the flashboard, the nut 6 is connected with the leading screw 7 with 6 thread fitting of nut, described
7 lower part of leading screw is located in 2 body of flashboard, and 7 top of leading screw is exposed outside in flashboard 2.The leading screw 7 is located at the part on the outside of flashboard
It is connected with and screws handle 8.
The part that the leading screw 7 is located in flashboard can do the movement rotated in flashboard, so as to which flashboard be driven to transport up and down
It is dynamic.
The O-ring seals 5 are rubber material.The O-ring seals 5 are hinged in ring dress dovetail groove.
