Abstract
The utility model discloses a rubber sealing element for a water gate, which comprises a circular head and a support arm which are connected into a P shape, wherein, the joint is an arc transition; one end of the support arm is equipped with a square head; an inner side and an outer side of the joint of the square head and the support arm are right angles; and the circular head, the square head and the support arm are connected to form a notch shape. The rubber sealing element has simple structure and good sealing effect and can be tightly attached to a water gate wall under smaller water pressure; and the rubber sealing element is applicable to modification and use of small and medium-sized waterhead hydro-power gates and a water storage tidal gate.
Description
Technical field
The utility model relates to a kind of sluice rubber seal, relates in particular to the special-shaped sluice rubber seal of a kind of P.
Background technology
The effect of sluice rubber seal is to prevent to leak, and is an important component part of hydroelectric project gate.The sluice rubber seal is widely used in the antipriming of all kinds of gates of water conservancy, water power and municipal engineering construction, is specially adapted to the sealing of medium and small head water conservancy gate and the two-way water stop of water-storage and tide-retaining gate.The gate water seal is the crucial accessory of all kinds of steel gate sealings in the Hydraulic and Hydro-Power Engineering, and the height of its quality level had both influenced the safe operation of hydraulic gate, also influences the safety of hydraulic structure.
At present water conservancy, water power unit in charge of construction be in middle-size and small-size water conservancy, hydroelectric project, and using many is P type sluice rubber seal.Because P type sluice rubber seal has unique sealing function, it can make the P type water seal head of the P type sluice rubber seal that is installed on the gate be close to the gate wall by hydraulic pressure, thus the enhanced leaktightness effect.If but under the too low situation of water level, so that the water seal head is close to the gate wall, sealing performance just reduces the pressure of water body with regard to deficiency, causes the gate infiltration, leaks.
The utility model content
When the technical problems to be solved in the utility model is the insufficient pressure of water body, be difficult to make the water seal head to be close to the gate wall, sealing performance reduces, and causes the gate infiltration, leaks.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of sluice rubber seal, comprise round head and support arm, round head and support arm connect into the P type, the junction is an arc-shaped transition, the support arm other end also is provided with the square head, and the medial and lateral of itself and support arm junction are the right angle, and round head, square head and support arm are connected to form recess shape.
Set up a square head at the other end of support arm, can make the special-shaped water seal of P have dual sealing function, thus the enhanced leaktightness effect.
Be the sealing effectiveness of further enhanced leaktightness spare, round head is gone up circle centre position and is provided with through hole.Design like this, help increasing the elasticity of seal, make the head of sluice rubber seal under less hydraulic pressure, also can be close to the gate wall.
The utility model has the advantages that: simple in structure, good sealing effect, under less hydraulic pressure, just can be close to the gate wall, be fit to repacking, the use of medium and small head water conservancy gate and water-storage and tide-retaining gate.
Description of drawings
Fig. 1 is a stereogram of the present utility model;
Fig. 2 is a sectional drawing of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the special-shaped sluice rubber seal of P comprises round 4, square head 1 and support arm 2, and round 4 connects into the P abnormity with support arm 2, and the interior outside of junction is an arc-shaped transition; Square head 1 is that the right angle is connected with the interior outside of support arm 2 junctions, round 4, square head 1 and support arm 2 threes form an inner recess 30, round 4, square head 1 have the sealing function, and be provided with through hole 3 for round 4, through hole 3 makes seal have better elasticity, can make the head of sluice rubber seal just can be close to the gate wall like this under less hydraulic pressure.
Claims (2)
1. a sluice rubber seal comprises round head and support arm, and round head and support arm connect into the P type, the junction is an arc-shaped transition, it is characterized in that: the support arm other end also is provided with the square head, and the medial and lateral of itself and support arm junction are the right angle, and round head, square head and support arm are connected to form recess shape.
2. sluice rubber seal according to claim 1 is characterized in that: round head is gone up circle centre position and is provided with through hole.
