Description
Technical Field
The utility model relates to the technical field of valves, especially, relate to a check valve of wet rubbish delivery pump.
Background
The one-way valve is a device which enables materials to flow only along an inlet and prevents outlet media from flowing back, a piston and a piston spring are arranged in the general one-way valve, the purpose of limiting the two-way flow of fluid is achieved through the characteristics of a piston group, and therefore the one-way valve is also called as a check valve or a check valve.
In the process of treating wet garbage, the wet garbage is special in components and large in particle size, and in order to guarantee stable and normal material conveying of the pump body, the traditional check valve cannot meet the working requirement and is easy to cause damage to the valve core.
Therefore, the problem to be solved is to ensure the stability of the one-way valve in the process of conveying wet garbage.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a check valve to solve the check valve case fragile scheduling problem that the above-mentioned background art provided.
In order to achieve the above object, the utility model provides a following technical scheme: the design is a check valve of a wet garbage conveying pump, wherein a valve body flange is installed at the top of a valve body, a connector is connected above the valve body flange, an oil cylinder is installed above the connector, a water inlet pipe is connected to the bottom of the valve body, a water outlet pipe is connected to the side edge of the valve body, the check valve is characterized in that a guide pillar is arranged in the vertical direction inside the valve body, a spring is sleeved at the lower end of the guide pillar, a material walking ball is arranged below the spring, and a cushion block is arranged below the material walking ball.
Preferably, the middle of the valve body flange is provided with a groove and a high-pressure sealing ring, the high-pressure sealing ring is fixed by a gland, and the connection mode is bolt connection.
Preferably, the contact surface of the cushion block and the feeding ball adopts a cambered surface structure, and the cushion block is made of high-speed tool steel.
The utility model provides a pair of check valve of wet rubbish delivery pump, beneficial effect lies in: the utility model has the advantages of simple structure, stability and facilitate the use, walk the material ball and inhale material in-process compression spring at the pump body, ejection of compact in-process carries under the effect of spring force and hydraulic pressure, quick sealing feed inlet, the contact surface of cambered surface can be better play sealed effect. Is convenient for practical use.
Drawings
Fig. 1 is a schematic structural view of the check valve of the wet garbage transfer pump of the present invention.
In the figure: the device comprises a valve body 1, an oil cylinder 2, a connector 3, a guide pillar 4, a gland 5, a spring 6, a material passing ball 7, a water inlet pipe 8, a water outlet pipe 9, a cushion block 10, a valve body flange 11 and a high-pressure sealing ring 12.
Detailed Description
The technical solutions in the embodiments of the present invention are now described in detail with reference to the drawings of the present invention, and it should be understood that the described embodiments are only some embodiments of the present invention, but not all embodiments.
Referring to fig. 1, a check valve of a wet garbage transfer pump comprises a valve body 1, a valve body flange 11 is arranged at the top of the valve body 1, a connector 3 is connected above the valve body flange 11, an oil cylinder 2 is arranged above the connector 3, a water inlet pipe 8 is connected at the bottom of the valve body 1, a water outlet pipe 9 is connected at the side edge of the valve body 1, a guide pillar 4 is arranged in the valve body 1 in the vertical direction, a spring 6 is sleeved at the lower end of the guide pillar 4, a material conveying ball 7 is arranged below the spring 6, a cushion block 10 is arranged below the material conveying ball 7, the material conveying ball 7 can move up and down more smoothly, when the valve is in a closed state, the contact surface of the cushion block 10 and the feed ball 7 is in line contact, the effect of cutting off wet garbage materials can be achieved, better sealing performance is achieved, a groove is formed in the middle of the valve body flange 11, a high-pressure sealing ring is installed and fixed through a gland, and the connection mode is bolt connection. The sealing performance of the whole valve body can be ensured, and the valve is convenient to use in practice.
The above is only the best embodiment of the present invention, and the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, and according to the technical solution of the present invention and the design of the present invention, equivalent replacement or change should be covered within the protection scope of the present invention.
