Abstract
The present invention relates to a conical hammer eliminating check valve of an internal sealing type, which relates to a check valve on a water pump outlet pipeline in water industry and is mainly developed for solving the problems of complex devices, large volume, heavy weight and high flowing resistance of the existing check valve using a slow closing and hammer eliminating method. The check valve comprises a valve shell, an amplitude board, a support bracket, a fixed direction guiding sleeve, a valve flap, a valve axle, a spacing nut, a spring, etc. The corrosion material part of an inlet belt of a valve body is processed into an internal diameter sealing surface parallel to a central line of the valve body to form a no-ring radial sealing pair with the cylindrical sealing surface of the valve flap or the corrosion material part of the valve body or the valve flap is provided with a groove. A sealing ring belt is arranged in the groove to form the radial sealing pair with a sealing ring. A flexible bag and a sealing cover are additionally arranged in the valve to prevent sand, oil and other impurities from influencing the work of a valve flap axle. The support bracket between the bag and the cover is provided with holes for communicating the bag with the cover. A liquid adding pipe and a liquid adding valve are also arranged. The water hammer is eliminated by using a rapid costing method. The check valve has the advantages of simple structure, small volume, light weight and small flowing resistance.
Description
Technical field: the present invention relates to the safety check on a kind of exit of pump pipeline of water and wastewater industry.
Background technique: existing safety check generally adopts the Slow Close hammer method that disappears, and adopts this hammer method equipment complexity that disappears, and volume is big, and weight is big, and flow resistance is big.
Summary of the invention: the objective of the invention is to develop and a kind ofly eliminate water hammer with the speed method of closing, simple in structure, volume is little, and weight is little, the internal sealing type cone that flow resistance the is little hammer safety check that disappears.
Above-mentioned purpose is achieved in that the present invention has two ends to have the valve casing of the big tripe doleiform of flange, the internal surface of valve casing is to the support of its several disc of center beta radiation and the centerline formation valve body that fuses, the fixed guide cover is housed on support, flap and flap axle fuse, is furnished with stop nut at the flap the tip of the axis, between flap and support, spring is housed, we make the internal diameter sealing surface that parallels with the valve body center line with valve body inlet band corrosion resistant material place (when referring to that valve body or flap are made with non-corrosion resistant material), with the no circle radial seal pair of two light body sealing surfaces of column sealed composition at the external diameter band corrosion resistant material place that matches of flap.
Also can be on valve body inlet band corrosion resistant material place and internal diameter sealing surface that the valve body center line parallels or on column sealed of the external diameter band corrosion resistant material place of the flap that matches with it, establish the groove of installation seal ring, seal ring is fixed on or is installed in the groove, form the radial seal pair that seal ring is arranged.
In order to prevent circle, the seal ring that is fixed on flap or the valve body can vulcanize, clamp, adheres on flap or the valve body.
For the silt in the anti-sealing, the operation of burn into scale effect valve; we set up flexible pocket; one end sealing and fixing of flexibility capsule is on flap; the other end sealing and fixing is on the entry end of support; fix a seal closure at the outlet end of support, the flap axle is placed in capsule and the cover, on the support between flexible pocket and the seal closure, establish the hole both are communicated with; establishing the liquid-feeding tube that adds protective medium in cover or capsule on seal closure or the support, liquid-feeding tube stretches out the outer end of valve charging valve.Above-mentioned partition method of establishing flexible pocket and seal closure respectively at the entry end and the outlet end of support also can change the partition method that flexible pocket sealing is respectively established at two ends into.
Advantage of the present invention is to adopt the speed method of closing to eliminate water hammer, and simple in structure, volume is little, and weight is little, and flow resistance is little.
Description of drawings: accompanying drawing is a generalized section of the present invention.
Embodiment: with reference to accompanying drawing, two ends have the internal surface of big tripe doleiform valve casing 8 of flange to its center line, the support 12 of several disc of radiation 14 and the centerline formation valve body that fuses, fixed guide cover 2 is housed on support, flap 4 fuses with flap axle 1, is furnished with stop nut 9 at the flap the tip of the axis, spring 3 is housed between flap and support, we made the internal diameter sealing surface that parallels with the valve body center line with valve body inlet band corrosion resistant material place 7 (when referring to that valve body or flap are made with non-corrosion resistant material), with the no circle radial seal pair of two light body sealing surfaces of column sealed 6 composition at the external diameter band corrosion resistant material place that matches of flap 4.
Also can be on valve body inlet band corrosion resistant material place 7 and internal diameter sealing surface that the valve body center line parallels or column sealed 6 of the external diameter band corrosion resistant material place of the flap 4 that is matching with it on establish the groove of installation seal ring, seal ring is fixed on or is installed in the groove, form the radial seal pair that seal ring is arranged.
In order to prevent circle, the seal ring that is fixed on flap or the valve body can vulcanize, clamp, adheres on flap or the valve body.
For the silt in the anti-sealing, the operation of burn into scale effect valve; we set up flexible pocket 5; one end sealing and fixing of flexible pocket is on flap; the other end sealing and fixing is on the entry end of support; fix a seal closure 10 at the outlet end of support, flap axle 1 is placed in capsule and the cover, on the support between flexible pocket and the seal closure, establish hole 11 both are communicated with; establishing the liquid-feeding tube that adds protective medium in cover or capsule on seal closure or the support, liquid-feeding tube stretches out the outer end of valve charging valve 13.Above-mentioned partition method of establishing flexible pocket and seal closure respectively at the entry end and the outlet end of support also can change the partition method that flexible pocket sealing is respectively established at two ends into.
