Technical Field

The invention relates to a water inlet and outlet valve, in particular to a wedge-shaped strong water stop tooth transmission type water inlet and outlet valve.

Background

Adopt more traditional plate valve and ball valve at present, have not fully satisfactory part: the flat gate valve is slowly opened and has poor sealing effect, water is blocked, and water flow resistance is obviously increased; the ball valve structure requires high precision and is sealed by tight fit, the manufacturing cost is high, and the opening resistance is large; both the two have the inconvenience of operation and short service life, bring trouble and make engineering year shorten for engineering management maintenance.

The conventional flat gate valve has several disadvantages and shortcomings: 1. the width of the gate bottom plate is mainly determined by the water retaining height of the gate and the arrangement of the upper structure, the section is overhigh, and the water pressure is high; 2. the thickness of the gate bottom plate is determined by the internal force of the structure, the anti-skid stability and the local freezing depth. In the alpine region, the thickness of the gate bottom plate is generally 1.5 m-2.0 m, even more than 2.0 m; 3. anti-skid is often the controlling condition for stability of a flat foundation gate. The anti-slip force is determined by the self weight of the foundation and the upper structure and the friction coefficient between the water weight of the foundation and the foundation, the floating force generated under the foundation plate is larger than the weight of the water body on the foundation plate, and the anti-slip stability is very unfavorable. Meanwhile, a large amount of reinforced concrete materials are uneconomical when used as the weight; 4. in order to maintain stable seepage, the lengthening of the bottom plate or the lengthening of the upstream apron are often considered; 5. if a frozen soil layer is formed on the frost heaving foundation under the flat foundation, the gate can be subjected to the vertical frost heaving force which can hardly be resisted. This basic form is clearly applicable and necessary for barrage works with high water heads or traffic bridges on the top. But a great deal of waste is caused for the gate engineering of a large amount of low-water-head irrigation diversion canal heads.

In conclusion, the existing water inlet and outlet valve is not suitable for the gate engineering of the low-water-head irrigation diversion canal head.

Disclosure of Invention

The invention aims to solve the problem that the existing water inlet and outlet valve is not suitable for the gate engineering of the low-water-head irrigation water diversion canal head. Further provides a wedge-shaped strong water stopping tooth transmission type water inlet and outlet valve.

The technical scheme of the invention is as follows: a wedge-shaped strong water stop tooth transmission type water inlet and outlet valve comprises a gate plate frame, a gate plate and a transmission case, wherein the lower part of the gate plate is wedge-shaped, the gate plate frame is vertically connected to a pipeline or a water delivery channel, and the gate plate moves up and down in the gate plate frame through the transmission case; the transmission case includes driving rack, drive gear, handle and protecting cover, and the vertical setting of driving rack, and driving rack is connected with the upper end of flashboard, and drive gear rotates and installs in the upper portion of flashboard frame, and drive gear meshes with driving rack, and the handle is installed in the outside of flashboard frame and is connected with drive gear, and the protecting cover lid dress is in the flashboard frame upper end.

Furthermore, the device also comprises a plurality of plate frame fixing pieces, and the inner side wall of the pipeline or the water delivery channel is connected with the gate plate frame through the plurality of plate frame fixing pieces.

Furthermore, triangular irons are arranged on two sides of the lower end face of the flashboard.

Furthermore, the transmission case still includes rings, passes through rings between the upper end of transmission rack and the flashboard and connects.

Furthermore, the transmission case also comprises a limit bearing, and the limit bearing is rotatably arranged in the gate plate frame and is propped against the other end of the transmission rack.

Further, the transmission case also comprises a locking pin which is arranged on the protective cover.

Further, it still includes seal assembly, and seal assembly installs the bottom at the ram frame.

furthermore, the sealing assembly comprises two oval I-shaped sealing strips, an auxiliary plate and a sealing strip mounting plate, the sealing strip mounting plate is mounted on the inner side wall of the gate plate frame, one sides of the two oval I-shaped sealing strips are respectively inserted and mounted on the sealing strip mounting plate, and the two oval I-shaped sealing strips are connected through the sealing strip mounting plate in an inserted and mounted mode.

Compared with the prior art, the invention has the following effects:

1. The invention only needs to connect the plate frame fixing piece with the water supply pipeline, and the overflowing and water stopping of the pipe (channel) can be completed without too much material resources and financial resources.

2. The wedge-shaped gate has small gate opening and closing resistance, and is very convenient and quick to close and open. The problem that the existing brake bottom plate is inconvenient to close is effectively avoided.

3. The opening speed of the gear rack transmission is dozens of times faster than that of the screw rod, the screw rod can only move a few millimeters after rotating a circle, and the transmission can move a few hundred millimeters after rotating a circle; the lateral rotation opening and closing is more convenient than the horizontal rotation operation.

4. The invention adopts the oval I-shaped sealing strip for the automobile glass to ensure that the water-stopping effect is stronger.

5. The invention can work only by directly installing the invention on a pipe or a channel, thereby achieving the effects of saving labor, time and materials; the structure is simple and compact, and the device is directly connected with the structure, flexible to use, safe and reliable; and can finish water supply and water cut-off fast, has raised the working efficiency greatly, has realized the purpose of saving cost and reducing consumption, increasing the income.

6. The width of the gate of the invention is related to the width of the installed pipeline or water delivery channel, and the applicable environment is low water head irrigation water diversion, the common water channel irrigation water diversion of rice is narrow, the water pressure is controllable, and the gate can be opened and closed quickly through the wedge-shaped gate. In addition, the application environment of the invention is not affected by the problems of stable anti-skid, stable seepage, vertical frost heaving force and the like.
