Detailed Description

The utility model provides a gate valve for water supply system distribution pool and suction well entrance with simple structure and good cutting effect, as shown in fig. 1 and fig. 2. The gate valve, including flashboard 1 and seal assembly 2, seal assembly 2 arrange that one side of flashboard 1 backing water, the water-break in-process, the flashboard 1 of gate valve passes through seal assembly 2 and presses the leak protection on sealed basis under the cooperation of rivers pressure. This application is on the basis of the present slide valve that constitutes including flashboard 1 and seal assembly 2, through improving seal assembly 2 for arranging that a side of flashboard 1 back of water, then makes the water-break in-process, and the flashboard 1 of slide valve comes the leak protection on sealed basis through seal assembly 2 pressure down in the cooperation of rivers pressure. The current situation that reliable sealing cannot be achieved when hard sealing is adopted in the prior art is changed, or the sealing element is arranged on one side of the upstream face of the gate plate, tight combination of the sealing element and the sealing base cannot be guaranteed due to hydraulic action, the leakage is avoided due to untight closing, and the sealing and cutting-off effect of the gate valve is improved. Simultaneously, owing to only improved on the subassembly of sealing member to guaranteed this application the simple structure's of slide valve characteristics itself.

In the above-mentioned embodiment, for submitting the combination effect between sealing component 2 and the sealed basis as far as possible, the gate valve of this application still include installation frame 3, installation frame 3 adorn admittedly in the channel of distribution tank and suction well entrance, sealed basis set up installation frame 3 on, flashboard 1 through the movable arrangement of installation frame 3 on the channel of distribution tank and suction well entrance. In this case, the mounting frame 3 is preferably a square frame made of channel steel.

Further, in order to reduce the weight of the gate valve and facilitate the opening or closing operation, particularly the labor intensity when the gate plate is opened or closed manually, the gate plate 1 is a planar steel gate plate with a weight reduction cavity 4, and reinforcing ribs 5 are arranged in the weight reduction cavity 4.

Simultaneously, in order to reduce operating personnel's intensity of labour as far as, the flashboard valve of this application still include lifting unit 6, flashboard 1 through lifting unit 6 promote and descend. At this time, the lifting assembly 6 at least has the following two structures, one structure is an automatic lifting assembly comprising a driving motor, and the power output end of the automatic lifting assembly is connected with the upper end of the flashboard 1. That is to say, rise and fall process all are gone on under driving motor's cooperation, and operating personnel only presses the shift knob can, and operating personnel's intensity of labour is minimum certainly this moment, but it also has the shortcoming, and it is very easy to damage under the open-air operating mode for a long time that driving motor is in, and the running cost is higher.

The present application thus provides another lifting assembly in the form of a lifting assembly 6, namely a manual lifting assembly comprising a lifting rod 7, wherein the lower end of the lifting rod 7 is connected to the upper end of the shutter 1. At this time, the manual lifting assembly further includes a bevel gear 8, and the lifting rod 7 is lifted or lowered by the bevel gear 8. Of course, the structure form of the gear and the rack matching can be realized. Accordingly, the lifting rod 7 is a full-threaded rod, a protective sleeve 9 is arranged above the bevel gear 8, and the lifting rod 7 in the lifting process is protected by the protective sleeve 9. The manual lifting assembly further comprises an operating handle wheel 10, and the bevel gear 8 rotates under the coordination of external force through the operating handle wheel 10. The operability can be improved by operating the handle wheel 10.

In conclusion, the gate valve that adopts this application to provide still has following characteristics and advantage, and its characteristics are that the gate plate bottom and left and right side lean on channel-section steel frame backwater side to implement three rubber seal face and seal, and the top through increase the gate plate height surpass the surface of water can, need not to adopt sealedly to realize that the pond exempts from the leaking stoppage and cuts off the water. The application provides the advantage of technique that the investment is little, safe and reliable, and the practicality is strong, and light cutting off water need not to arrange artifical leaking stoppage.

Example one

The technology provided by the application is mainly manufactured aiming at the problem that the existing simple square gate valve is difficult to measure due to water cut, and the following means is mainly adopted, firstly, the rubber sealing gasket is adopted for sealing, the gate is durable, and the rubber sealing gaskets are only required to be arranged at the lower part and two side edges of the gate, so that the problem that no sealing gasket or the sealing gasket material is poor is solved; secondly, the mounting direction of the sealing gasket for plugging the window is changed, namely the sealing gasket is changed from a water side to a back water side, the edge sealing gasket of the flashboard is extruded to one side of the channel steel by utilizing the pressure of the water source side to realize automatic sealing, and wedge-shaped keys arranged on the inner side of the channel steel are not needed for guiding; thirdly, the height of the flashboard is increased, the height of the flashboard is larger than or equal to the height of the water level, and the water leakage phenomenon at the upper end of the flashboard is thoroughly eradicated, so that the water tank is prevented from leaking and stopping water.

The concrete design scheme of this application simple and easy square slide valve does: channel steel with the width of 100mm is used as a framework of the gate valve. The width of the frame is the width of the water outlet window, the height of the frame is the height of the water level of the water distribution channel and the height of the water outlet window, and the water outlet window is fully opened when the flashboard is in an opening state. Secondly, a steel plate with the thickness of about 3-5mm is processed into a hollow gate plate with the thickness of 50-60 mm. The height of the gate plate is slightly higher than the water surface height of the water distribution channel. Thirdly, the middle plate surface of the hollow gate plate is provided with a rib plate with the width of 50mm and the thickness of 20mm so as to increase the strength of the gate plate. And fourthly, adding rubber sealing gaskets with the thickness of 5-10mm and the width of 20-30mm below and on the left side and the right side of the hollow gate plate for sealing. The rubber sealing gasket is directly fixed on the flashboard with the screw thread hole by using an inner hexagon screw. Sixthly, the diameter of the valve rod is about 50mm, a full screw rod is adopted, and the height of the screw rod is equal to the height of the window of the inlet of the water pool and then a margin of 200mm is reserved. And the screw rod is provided with a protective sleeve. The square gate valve operation handle wheel adopts an umbrella gear type handle wheel with the diameter of about 500 mm. Ninthly, a bevel gear device and a screw with a valve rod inside. And the R, the screw rod and the flashboard connecting pin.
