Abstract
The utility model provides a pressurized water seal which comprises a water seal head, a left wing head and a right wing head; the water seal head, the left wing head and the right wing head are connected into a whole, the cross section of the integrated water seal body is Mountain-shaped. The utility model improves the structure of water seal and changes the cross section of water seal structureinto Mountain-shaped so that the contact surface of water seal and water flow is reduced and the impact force of high speed water flow on water seal body is reduced; the pressurized water seal has reasonable design, convenient process and good integrity; the water seal head is telescopic and has good water sealing effect; the cost is reduced, the safe operation service life of gate water seal device is greatly improved and the pressurized water seal is applicable to reassembly and use of high water head gates.
Description
Technical field
The utility model relates to a kind of water cut-off device, and particularly relevant for a kind of pressurising water seal.
Background technique
Water conservancy, the employed water seal of water power unit in charge of construction mainly are conventional water seals such as P type water seal at present, adopt conventional water seal, when working head when 80m is following, the stagnant water effect of conventional water seal still can, but working head water sealed joint and corner when 80m is above just jetting occurs easily, and the jetting phenomenon can be more and more serious with the growth of reservoir level.In case water seal is leaked, conventional water seals such as P type water seal are easily vibrated under high-speed jet, produce noise, and behind the gate opening, high speed water fails to be convened for lack of a quorum the water seal rubber is torn; Water seal pressing plate lengthening can only be strengthened, the bracketed part of P type water seal is shortened and compress, thereby eliminate the vibration and noise source, noise is disappeared, but its stagnant water effect reduce greatly again.
The model utility content
The utility model proposes a kind of pressurising water seal, reduced the surface of contact of water seal head and current, reduce the impulse force of high-velocity flow water seal.
For reaching above-mentioned purpose, pressurising water seal of the present utility model comprises water seal head, left wing's head and right flank head, and water seal head, left wing's head and right flank head connect as one, and its cross section is " mountain " shape.
In the utility model, the upper surface and the lower surface of left wing's head and right flank head also have groove.
In the utility model, the bottom of pressurising water seal has arc-shaped recess.
The utility model has improved the structure of water seal, make its cross section be " mountain " shape, reduced the surface of contact of water seal and current, reduce the impulse force of high-velocity flow the water seal body, reasonable in design, technology is easy, good integrity, a water seal flexible, water sealing effect is good, reduce cost, prolonged gate sealing water device safe operating life greatly, be fit to the repacking and the use of all kinds of high head water conservancy gates.

Embodiment
For above-mentioned and other purpose, feature and advantage of the present utility model can be become apparent, preferred embodiment cited below particularly, and conjunction with figs. are described in detail below.
Figure 1 shows that the utility model embodiment's stereogram, Figure 2 shows that the sectional drawing of the utility model embodiment's pressurising water seal, please also refer to Fig. 1 to Fig. 2.
Cross section of the present utility model is " mountain " shape, specifically comprises water seal 10, left wing 20, right flank 30, left limb arm 40 and right limb arm 50, aspect ratio left wing of water seal 10 20 and right flank 30 height.Left side limb arm 40 connects the left side of left wings 20 and water seal 10, and the left bayonet socket 60 of formation between left wing 20 and the water seal 10; Right limb arm 50 connects the right side of right flanks 30 and water seal 10, and the right bayonet socket 70 of formation between right flank 30 and the water seal 10.
In the present embodiment, the upper surface and the lower surface of left wing 20 and right flank 30 also have groove 80.
In the utility model, the utility model bottom has arc-shaped recess 90, can increase the stretchability of water seal 10 like this.
When making pressurising water seal of the present utility model, at first kneading and on extruder extruding and moulding semi-finished product water seal body.Then, water seal body semi-finished product put into the die cavity of vulcanizer and ajust,, matched moulds production obtains pressurising water seal of the present utility model.The process that matched moulds production obtains novel pressurising water seal belongs to the common processes of existing preparation rubber product usually the people of knowledge in having related domain, do not repeat them here.
During installation, groove 80 is that screw fixedly is installed during the utility model, purpose is to make the upper surface of the spiral shell head of fastening screw and nut and left wing 20 and right flank 30 and lower surface at grade, press the gate pressing plate on two side limbs, and block at bayonet socket 60 and 70 places, whole pressurising water seal only stays water seal 10 outside, so that reduce the impulse force of current to the gate water seal when gate opening.Behind the gate standard-sized sheet, water seal 10 can be reduced to below the gate pressing plate, and high-velocity flow can not damage water seal, prolongs water seal working life greatly.
The utility model has improved the structure of water seal, and making cross section is " mountain " shape, reduces contacting in sum of water seal and current, the utility model is under the situation that does not change the rubber material, utilize original production technology, improved the structure of water seal, making cross section is " mountain " shape.The utility model is reasonable in design, need not change original production technology, good integrity, and transportation, installation are all convenient.Water seal head position is connected more firm with two side limbs, and two sections limb arms of water seal body are fastened on the gate with screw respectively, also block with cover plate on the surface, have only the water seal head to be exposed during gate work, significantly reduced the impulse force of current to water seal, in the corresponding working life that prolongs water seal, the sealability of water seal has also improved.The utility model is fit to repacking, the use of the sealing of large and medium-sized water conservancy and hydropower gate and high head plane gate and gates of segmental shape, gives each water conservancy, the water power unit in charge of construction space that provides more choices, and has improved the practicability of water seal product effectively.
Concrete case study on implementation only is a preferable case study on implementation of the present utility model described in the utility model, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be as technology category of the present utility model.
