Abstract
The utility model discloses a multi-pedaled buoyant box type check valve which comprises a valve body which mainly consists of a main valve body (1) and an auxiliary valve body (13) by hermetic connection, wherein the inner walls of the auxiliary valve body (13) and the main valve body (1) are respectively fixedly connected with an upper rotating shaft (8) and a lower rotating shaft (4), and the upper rotating shaft (8) and the lower rotating shaft (4) are respectively and movably connected with an upper valve pedal (7) and a lower valve pedal (3) which are of buoyant box type structures; and holes for liquid to flow through are respectively formed right below the projections of the upper valve pedal (7) and the lower valve pedal (3) in the valve body. When the multi-pedaled buoyant box type check valve is used, the multi-pedaled buoyant box type check valve has the advantages of stable running, high flow, light valve pedals, small opening resistance and small water head loss, and when the multi-pedaled buoyant box type check valve is closed, the multi-pedaled buoyant box type check valve has the advantages of no impact, no noise and good sealing effect, and water hammers can be effectively eliminated.
Description
Technical field
The utility model relates to safety check, relates in particular to Swing check valve.
Background technique
At present; Be provided with safety check mostly on the pipeline of industries such as oil, chemical industry, pharmacy, metallurgy, coal, power industry, urban water supply and sewerage; It leans on water pump and motor in the pipeline to promote the power that media flow produces and opens and closes automatically, and Applicable media is water, oil product, steam, acid medium etc.The main effect of safety check is to prevent that medium from flowing backwards, preventing water pump and the counter-rotating of drive motor machine thereof, and Swing check valve is selected in the operation of guarantee network security usually for use.The operation injustice was steady when the Swing check valve that the heavy caliber pipeline is selected for use used, and flap is heavy, opening resistance is big, energy consumption is big, it is fast to close, impact noise is big, sealing surface wear is fast, can't eliminate water hammer.Can cause the damage of valve, pipeline or water pump and drive motor equipment thereof when serious.
Summary of the invention
The purpose of the utility model operates steadily when providing a kind of the use, flow is big, flap is light, opening resistance is little, energy consumption is little, it is slow to close, noise free when closing, eliminate many lobes floating box type safety check of water hammer effectively.
The technological scheme of the utility model is: a kind of many lobes floating box type safety check; It comprises the valve body that mainly is tightly connected and is constituted by main valve body and auxiliary valve body; Said auxiliary valve body and main valve body inwall are connected with rotating shaft and lower rotary shaft respectively; Said upward rotating shaft and lower rotary shaft are connected with the last flap and the lower Disc of floating box type structure respectively, and flap and lower Disc orthographic projection below has the hole that passes through for liquid on the said valve inner.
The improvement of such scheme is to be connected with the flange that extends to valve inner on the described auxiliary valve body.
The further improvement of such scheme is that described lower rotary shaft upper end is connected with the lower Disc caging bolt.
Further improving of such scheme is to be connected with the matrix link that restriction lower Disc caging bolt rotates between the described hole.
Further improving again of such scheme is to be connected with seal ring between described hole two ends and the valve inner.
The beneficial effect of the utility model is owing to adopt multi-clove type, and go up flap, lower Disc adopts the floating box type structure, make go up flap, lower Disc is in light weight, and floating function is arranged during unlatching, buoyancy adds the thrust of water, makes flap, lower Disc be prone to unlatching.When closing, buoyancy is arranged equally, make when flap is closed, do not have bump, noise is little, and closing velocity is mild.
Description of drawings
Fig. 1 is the utility model generalized section;
Fig. 2 is that the utility model is opened the schematic representation that puts in place.
Embodiment
As shown in Figure 1; The embodiment of the utility model is: the valve body that mainly is tightly connected and is constituted by main valve body 1 and auxiliary valve body 13; Said auxiliary valve body 13 is connected with rotating shaft 8 and lower rotary shaft 4 respectively with main valve body 1 inwall; Said upward rotating shaft 8 and lower rotary shaft 4 are connected with the last flap 7 and lower Disc 3 of floating box type structure respectively, and flap 7 has the hole that passes through for liquid with lower Disc 3 orthographic projections below on the said valve inner.
The preference of the utility model is that main valve body 1 adopts airflow design with auxiliary valve body 13, and main valve body 1 is connected through major-minor valve body clamping bolt 9 with auxiliary valve body 13, major-minor valve seals 10 is installed on major-minor valve body clamping bolt 9 is played the waterproof sealing effect.The valve inleting water mouth adopts the taper deflector, operates steadily thereby reach, and flow is big, and noise is little, the purpose that loss of head is less.It is sagging naturally to go up lower Disc when valve cuts out, and covers the hole of below.Owing to adopt the bivalve diplopore, and go up flap 7, lower Disc 3 adopts the floating box type structures, make go up flap 7, lower Disc 3 is in light weight, because floating function, adds the thrust of water during unlatching, makes flap 7, lower Disc 3 be prone to unlatchings.When closing, buoyancy is arranged equally, make when flap is closed, do not have bump, noise is little.For further reducing impact force and keeping better seal property, be connected with seal ring 2 between hole two ends and the valve inner, seal ring 2 adopts hollow P type adhesive tape, and when closing, last flap 7 is littler with 3 pairs of valve body impact forces of lower Disc, and sealing effect is better.12 pairs of the flanges that extends to valve inner on the auxiliary valve body 13 are gone up flap 7 and are played position-limiting action, go up flap 7 during unlatching and upwards rotate with rotating shaft, stop operating during contact flange 12.Flange 12 is fixed on the auxiliary valve body 13 through flange clamping bolt 11; Lower Disc caging bolt 5 on the lower rotary shaft 4 when opening with pivoted downward; The concave surface of running into the matrix link between the hole stops operating; As shown in Figure 2, so and flange 12 play the effect of the upper and lower flap folding of common control angle, avoid too much too urgent through the current in the valve body.
Claims (5)
1. the safety check of lobe floating box type more than a kind; It is characterized in that it comprises the valve body that mainly is tightly connected and is constituted by main valve body (1) and auxiliary valve body (13); Said auxiliary valve body (13) and main valve body (1) inwall are connected with rotating shaft (8) and lower rotary shaft (4) respectively; Said upward rotating shaft (8) and lower rotary shaft (4) are connected with the last flap (7) and the lower Disc (3) of floating box type structure respectively, and flap on the said valve inner (7) and lower Disc (3) orthographic projection below have the hole that passes through for liquid.
