Description

One kind is without abrasion ball check valve

Technical field

Check-valves technical field is the utility model is related to, it is specially a kind of without abrasion ball check valve.

Background technology

Check-valves refers to flow in itself by medium and automatic open and close flap, for preventing the valve of medium refluence, also known as Non-return valve, check valve, reflux valve and counterbalance valve.Check-valves belongs to a kind of automatic valve, its main function be prevent medium flow backwards, Prevent pump and the drive motor from inverting, and vessel media is released.But traditional check valve structure is complicated, and sealing is poor, stream Measure small, resistance is big, and the loss of flood peak is big, it is therefore desirable to improves.

Utility model content

The purpose of this utility model is to provide one kind without abrasion ball check valve, to solve to propose in above-mentioned background technology The problem of.

To achieve the above object, the utility model provides following technical scheme：One kind is without abrasion ball check valve, including valve Body, the valve body is that body is set, and the upper and lower ends of valve body are respectively equipped with export and import, the right side one of the valve body into Type has connecting tube, and the internal diameter of the connecting tube is gradually reduced from left to right, and the inside of the valve body is provided with globe disk, the company The right-hand member of adapter is installed with sealing plate.

Preferably, the right-hand member of the connecting tube leads to integrally formed with annular connecting plate, the annular connecting plate with sealing plate Bolt is crossed to be fixedly connected.

Preferably, middle part the inner of the sealing plate is plugged on company integrally formed with grafting block, the inner of the grafting block The inside right-hand member of adapter.

Preferably, the bottom left of the upper end valve body of the import is provided with the first arc groove vertically.

Preferably, the inner of the grafting block is provided with the second arc groove vertically.

Preferably, the outer wall of the globe disk is enclosed with rubber layer.

Preferably, the upper and lower ends of the valve body are equipped with flange.

Compared with prior art, the beneficial effects of the utility model are：This is closed without abrasion ball check valve, Silenced, Water hammer, good seal performance are not produced, valve body uses full water stream channel, and flow is big, and resistance is small, and the loss of flood peak is smaller than swing type by 50%, It is adapted to large-scale promotion.

In figure：1 valve body, 2 outlets, 3 imports, 4 connecting tubes, 5 globe disks, 6 rubber layers, 7 sealing plates, 8 annular connecting plates, 9 bolts, 10 first arc grooves, 11 grafting blocks, 12 second arc grooves, 13 flanges, 14 water pumps, 15 outlet pipes.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment obtained, belong to the scope of the utility model protection.

Referring to Fig. 1, the utility model provides a kind of technical scheme：It is a kind of without abrasion ball check valve, including valve body 1, The valve body 1 is set for body, and the upper and lower ends of valve body 1 are respectively equipped with outlet 2 and import 3, the right side one of the valve body 1 Connecting tube 4 is formed, the internal diameter of the connecting tube 4 is gradually reduced from left to right, and the inside of the valve body 1 is provided with globe disk 5, The right-hand member of the connecting tube 4 is installed with sealing plate 7.

Specifically, the right-hand member of the connecting tube 4 is integrally formed with annular connecting plate 8, the annular connecting plate 8 and sealing plate 7 are fixedly connected by bolt 9.Facilitate the installation of sealing plate 7.

Specifically, middle part the inner of the sealing plate 7 is integrally formed with grafting block 11, the inner grafting of the grafting block 11 In the inside right-hand member of connecting tube 4.The inner of grafting block 11 is plugged on the inside right-hand member of connecting tube 4, improves sealing, while by In the positioning of sealing plate 7.

Specifically, the bottom left of the upper end valve body 1 of the import 3 is provided with the first arc groove 10 vertically.Work as globe valve When valve 5 is stuck in the bottom of valve body 1, the left end of globe disk 5 is located at the inside of the first arc groove 10, improves sealing.

Specifically, the inner of the grafting block 11 is provided with the second arc groove 12 vertically.When current by globe disk 5 to the right On when rushing, be advantageous to the inside that globe disk 5 is stuck in the second arc groove 12.

Specifically, the outer wall of the globe disk 5 is enclosed with rubber layer 6.The elasticity of rubber layer 6 left and right improves sealing, The internal structure of valve body 1 is protected simultaneously.

Specifically, the upper and lower ends of the valve body 1 are equipped with flange 13.The convenient connection with water pump 14 and outlet pipe 15.

This is without abrasion ball check valve, right angle setting during use, the outlet 2 and import 3 of valve body 1 respectively with outlet pipe 15 and The outlet pipe connection of water pump 14, as shown in figure 3, the globe disk 5 wrapped up using rubber layer 6, can be in valve in the presence of medium Monoblock type in body 1 slides into be rolled up and down, and so as to open or close valve, Silenced is closed, and does not produce water hammer, sealing Can be good, valve body 1 uses full water stream channel, and flow is big, and resistance is small, and the loss of flood peak is smaller than swing type by 50%, right angle setting, can be used for In cold water, hot water, industry and domestic water pipe network system, more applicable proof submersible sand discharging pump, medium temperature is 0 to 80 degree Celsius.Cause This this closed without abrasion ball check valve, Silenced, do not produce water hammer, good seal performance, valve body 1 uses full water stream channel, stream Amount is big, and resistance is small, and the loss of flood peak is smaller than swing type by 50%, is adapted to large-scale promotion.
