Abstract
The utility model provides a P-type water gate rubber seal part which comprises a P-type head and a support arm connected with the P-type head; the lateral side of the connection part of the head partand the support arm has arc-shaped transition and forms an arc-shaped concave notch. The utility model further improves the structure of P-type water seal in prior art and designs an arc-shaped concave notch on the lateral side of the connection part of the P-type head and the support arm so that the head part of the P-type water seal has more elasticity, is softer and provides more choices for various water conservation and hydropower construction units.
Description
Technical field
The utility model technology relates to a kind of sluice rubber seal, and particularly relevant for a kind of P type sluice rubber seal.
Background technique
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 water cut-off device 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, sealability just reduces the pressure of water body with regard to deficiency, causes the gate infiltration, leaks.
The model utility content
The purpose of this utility model is to provide a kind of water seal head position more whippy P type sluice rubber seal, just can make the water seal head be close to the gate wall under less hydraulic pressure.
For reaching above-mentioned purpose, the utility model provides a kind of P type sluice rubber seal, comprises P type head, the support arm that is connected with P type head, and the outside of head and support arm joint is arc-shaped transition, forms arc-shaped notch.
The utility model has carried out further structure of modification on the basis of P type water seal, designed an arc-shaped notch in the outside of P type head and support arm joint, make P type water seal more high resilience of head position, soft more, give each water conservancy, the water power unit in charge of construction space that provides more choices.
Description of drawings
Figure 1 shows that the utility model embodiment's stereogram.
Figure 2 shows that the sectional view of P type sluice rubber seal among Fig. 1.
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 view of P type sluice rubber seal among Fig. 1.Please also refer to Fig. 1 and Fig. 2.
P type sluice rubber seal 100 comprises P type head 10, support arm 20, and the outside of head 10 and support arm 20 joints is an arc-shaped transition, forms arc-shaped notch 30.Head 10 and support arm 20 connect into P shape, and arc-shaped notch 30 is positioned at the outside of head 10 and support arm 20 joints.Camber recess 30 makes the P type head 10 of water seal body 100 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.In the present embodiment, the number of degrees of arc-shaped notch are preferably 30 degree, only limit to this yet the utility model is originally non-.
When making P type sluice rubber seal 100 of the present utility model, at first kneading and on extruder the semi-finished product of extruding and moulding P type sluice rubber seal 100.Then, P type sluice rubber seal 100 is put into the die cavity of vulcanizer and ajust, matched moulds production obtains P type sluice rubber seal 100.The process that matched moulds production obtains P type sluice rubber seal 100 belongs to the common processes of existing preparation rubber product usually the people of knowledge in having related domain, do not repeat them here.
In sum, the utility model is reasonable in design, need not change original production technology, good integrity.P type sluice rubber seal head more is rich in pliability, transportation, installation are all convenient, can make the water seal head under less hydraulic pressure, just can be close to the gate wall, improved the sealability of water seal greatly, be fit to repacking, the use of medium and small head water conservancy gate and water-storage and tide-retaining gate, give each water conservancy, the water power unit in charge of construction space that provides more choices, 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.
Claims (2)
1. a P type sluice rubber seal comprises head and support arm, and head and support arm connect into P shape, it is characterized in that the outside that comprises head and support arm joint is an arc-shaped transition, forms arc-shaped notch.
2. P type sluice rubber seal according to claim 1 is characterized in that, wherein the number of degrees of arc-shaped notch are 30 degree.
