Abstract
A novel overwater bottom valve comprises a valve plate, a rubber blanket and a sealing flange, wherein the rubber blanket and the valve plate are arranged in the inner cavity at the joint of the sealing flange and the valve body; a valve rod sequentially penetrates a fastening plate, the rubber blanket and the valve plate from bottom to top, and the top part of the valve rod is inserted into an inner cavity of a guide rod at the center of a blank cap; a valve body upper flange is arranged at the upper end of the valve body, the rubber blanket is arranged between the valve body upper flange and the blank cap, and the rubber blank is tightly locked after a bolt penetrating the blank cap and the valve body upper flange. The novel overwater bottom valve has unique sealing performance, avoids water leakage and alleviates the damage caused by the water hammer; has remarkable energy-saving effect by saving about 5% to 7% of energy during normal use; has simple and compact structure, occupies small space, and has low cost and wide application range; and has long service life, is convenient to maintain, has reliable self-suction performance, and can ensure the next smooth pump starting.
Description
Technical field: the utility model relates to a kind of novel above-water type bottom valve, is widely used in the water pump auxiliary facility of industries such as petrochemical industry, chemical industry, weaving, printing and dyeing, metallurgy, mine.
Background technique: every water pump will be installed a bottom valve, and bottom valve is a kind of valve of energy-conservation source, generally is installed in water pump suction pipe and bottom under water, and restriction water pump liquid in pipe returns the water source, plays the function of only import but no export.A lot of water intakes and stiffening rib are arranged on the valve gap, on the pipeline that is mainly used in drawing water, old-fashioned bottom valve poor sealing performance, often occur after the termination of pumping can not water outlet problem.The above-water type bottom valve then is installed on more than the water surface, and it is the Updated product of old-fashioned bottom valve, is desirable diversion equipment, and also can replace vacuum pump and vacuum pumping device.Energy-saving effect is obvious, and is difficult for blocking.The product of present above-water type bottom valve, the valve seat that has guiding rib causes Heavy Weight, and physical dimension is huge, and its excessive weight makes liquid stream be subjected to bigger resistance; Owing to have the valve seat of guiding rib, guiding rib reduces useful water area after valve plate is opened, and makes the liquid miscarriage give birth to eddy current, increases the resistance to liquid stream; Complex structure, usefulness is artificial many during manufacturing, material is many, and the cost height is installed and storing takes up room greatly.
Summary of the invention:
The purpose of this utility model is exactly that a kind of novel above-water type bottom valve will be provided, and it can overcome the existing existing deficiency of above product.The purpose of this utility model is achieved in that a kind of novel above-water type bottom valve, is made up of valve plate, rubber pad, sealing flange, it is characterized in that: in the inner chamber of sealing flange and valve body joint, be provided with rubber pad, valve plate; Valve rod passes mounting plate, rubber pad, valve plate from bottom to up respectively, and insert in the inner chamber of the central guide rod that is provided with of stifle at the top; Described valve rod is provided with two kinds, a kind ofly is lower end band tip and passes the sealing flange lower end surface that another kind of valve rod lower end is that flush end is arranged in the sealing flange; Described valve body upper end is provided with the valve body upper flange, is provided with rubber pad between valve body upper flange and the stifle, and passes stifle and the locking of valve body upper flange by bolt.The utility model is installed on 90 ° of turnings of above horizontal pipe of the water surface and intake pipe, also can replace elbow, and its sealability uniqueness reaches watertight, slows down water hammer harm; Energy-saving effect is remarkable, can save energy about 5-7% when proper functioning is used; Simple and compact for structure, take up space little, cost is low, the use field is wide; Long service life, easy to maintenance, self-priming performance is reliable, can guarantee carrying out smoothly of pump startup next time.
Description of drawings:
Fig. 1 is the utility model structural representation; 1. guide rod, 2. stifle, 3. rubber pad, 4. valve body upper flange, 5. valve body, 6. valve rod, 7. valve plate, 8. rubber pad, 9. sealing flange, 10. mounting plate.
Embodiment: the utility model is described in further detail below in conjunction with accompanying drawing;
A kind of novel above-water type bottom valve is made up of valve plate 7, rubber pad 8, sealing flange 9, it is characterized in that: in the inner chamber of sealing flange 9 and valve body 5 joints, be provided with rubber pad 8, valve plate 7; Valve rod 6 passes mounting plate 10, rubber pad 8, valve plate 7 from bottom to up respectively, and insert in the inner chamber of the stifle 2 central guide rods 1 that are provided with at the top; Described valve rod 6 is provided with two kinds, a kind ofly is lower end band tip and passes sealing flange 9 lower end surfaces that another kind of valve rod 6 lower ends are that flush end is arranged in the sealing flange 9; Described valve body 5 upper ends are provided with valve body upper flange 4, are provided with rubber pad 8 between valve body upper flange 4 and the stifle 2, and pass stifle 2 and 4 lockings of valve body upper flange by bolt.During concrete enforcement, the utility model case material can be selected Reinforced Polypropylene, cast iron, carbon steel, stainless steel manufacturing for use.After the utility model carries out the housing pressure test by the JB/T9092 regulation, seepage must not be arranged or cause structural damage, the maximum allowable working pressure index is 0.6Mpa, and test pressure is 1.5 times of maximum allowable working pressure; Dwell time 〉=90s; Carry out the housing seal test by the JB/T9092 regulation, sealing part should not have leakage, and the maximum allowable working pressure index is 0.6Mpa, and test pressure is 1.1 times of maximum allowable working pressure; Dwell time 〉=30s; The utility model outward appearance should be smooth smooth, no burr, crackle, shrinkage cavity, sand holes, rough defective.The combination of valve plate and valve rod should be firmly, reliably.Valve plate moves up and down and answers flexibility and reliability, no stuck phenomenon.
