Abstract
The utility model discloses a butt clamp butterfly check valve valve body foundry goods, including valve body and disk seat, the disk seat is located in the valve body, the disk seat includes the supporting shoe, the mounting groove of a pair of symmetry is offered to the valve body, the both ends of supporting shoe respectively with the two mounting grooves intercommunication of symmetry, the mounting groove is crescent, and the both ends at the whole story of mounting groove are equipped with spacing, insert the installation axle of looks adaptation in the mounting groove, the installation axle also is crescent, the one side of installation axle is convenient for set up in the mounting hole for the plane, the direct plane from the installation axle of mounting hole is squeezed into up to getting through whole valve body, to install spacing the fixing in the mounting groove of axle and be provided with spacing at mounting groove both ends, even the mounting hole grow of valve body does not influence the leakproofness because the existence of the interior installation axle that sets up of mounting groove can not make the valve shaft take place the drunkenness, the interior life who changes the increase valve that dismantles of mounting groove can also be followed to the installation axle.
Description
Technical field
The utility model relates to a kind of valve body moulding, and more particularly, it relates to a kind of to folder butterfly check valve valve body moulding.
Background technique
Folder butterfly check valve is referred to and relies on medium flowing itself and automatic open and close flap, be used for the valve preventing medium from flowing backwards, also known as check valve, one-way valve, reflux valve and back pressure valve.Safety check belongs to a kind of automatic valve, and its Main Function prevents medium from flowing backwards, prevents pump and drive motor reversion, and the releasing of vessel media.In the prior art, butterfly check valve mostly is folder butterfly check valve, it comprises valve body and the semicircular butterfly flap of two panels of column, the semicircular butterfly flap of two panels is connected in valve body by valve shaft, valve shaft and valve body fix, mounting hole internal fixtion valve shaft is arranged in by the mounting hole valve shaft being opened in valve body, torsion spring is provided with to realize the keying of flap between flap and valve shaft, due to valve body be generally cylindrical on the surface of cylindricality punch operation more difficult, and the mounting hole got will inevitably make mounting hole become large under valve shaft is subject to fluid impact for a long time, become large mounting hole to make valve shaft that play can occur to cause the sealing of whole safety check to be destroyed.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of installation with valve shaft of offering folder butterfly check valve valve body moulding being convenient to mounting hole, can also improve the working stability of valve body.
For achieving the above object, the utility model provides following technological scheme: a kind of to folder butterfly check valve valve body moulding, comprise valve body and valve seat, described valve seat is located in valve body, described valve seat comprises support block, and described valve body offers the mounting groove of a pair symmetry, and the two ends of described support block are communicated with two mounting grooves of symmetry respectively, described mounting groove is crescent shape, and the two ends at the whole story of mounting groove are provided with positive stop strip.
By adopting technique scheme, suitable installation shaft is inserted in mounting groove, installation shaft is also in crescent shape, the one side of installation shaft is that plane is convenient to be opened in mounting hole, mounting hole is directly squeezed into from the plane of installation shaft until get through whole valve body, and being provided with positive stop strip is fixed in mounting groove at mounting groove two ends by spacing for installation shaft, even if the mounting hole of valve body becomes greatly because the existence of the installation shaft arranged in mounting groove can not make valve shaft generation play affect sealing, installation shaft can also disassemble the working life changed and increase valve in mounting groove.
As preferably, described valve seat offers circular groove.
By technique scheme, the setting of circular groove is concentrated for installing O-ring seal and can also reducing stress.
As preferably, described support block offers rectangular groove, and described rectangular groove is communicated with mounting groove.
By technique scheme, rectangular groove be arranged so that two panels flap is opened time surplus can be had to turn.
Accompanying drawing explanation
Fig. 1 is a kind of sectional view to folder butterfly check valve valve body moulding embodiment of the utility model;
Fig. 2 is a kind of structural representation one to folder butterfly check valve valve body moulding embodiment of the utility model;
Fig. 3 is a kind of structural representation two to folder butterfly check valve valve body moulding embodiment of the utility model.
Accompanying drawing illustrates: 10, valve body; 11, mounting groove; 12, positive stop strip; 20, valve seat; 21, support block; 22, sealing surface; 23, circular groove; 24, rectangular groove.
Embodiment
Folder butterfly check valve valve body moulding embodiment is described further to the utility model is a kind of referring to figs. 1 through Fig. 3.
One comprises valve body 10 to folder butterfly check valve valve body moulding, valve body 10 is provided with valve seat 20, valve seat 20 comprises is located at neutral position for separating the support block 21 of runner, the runner that support block 21 makes fluid enter into valve body 10 is divided into left and right twice, valve seat 20 offers circular groove 23, O-ring seal is set in circular groove 23, is used for improving sealing.
Valve body 10 offers the mounting groove 11 of a pair symmetry, the two ends that mounting groove 11 is located at support block 21 communicate with support block 21, mounting groove 11 is in crescent shape, positive stop strip 12 is respectively equipped with at the two ends of mounting groove 11, positive stop strip 12 and valve body 10 are wholely set, the surface of positive stop strip 12 is that circular arc is concentrated to reduce stress, the neutral position of support block 21 offers rectangular groove 24, rectangular groove 24 communicates with mounting groove 11, with rectangular groove 24, circular groove 24 is arranged so that valve seat 20 forms protruding sealing surface 22, sealing surface and flap abut against sealing, mounting groove 11 offers the below of circular groove 23, when being fit into installation shaft in mounting groove 11, installation shaft to be embedded in mounting groove 11 and by the spacing fixed installation axle of the positive stop strip 12 being arranged on mounting groove 11 two ends of left and right, replace the originally direct mode getting mounting hole on valve body 10, the plane of installation shaft gets mounting hole, mounting hole is got through through installation shaft and valve body 10, when offering mounting hole, operation easier declines and the also corresponding raising of the positioning precision of mounting hole, reinstall valve shaft.
Under the state of the long-time fluid impact valve shaft of original existence, mounting hole is worn and torn the sealing causing valve shaft generation play to affect valve body 10 under the extruding of valve shaft, and first installation shaft fixing in mounting groove 11 can be changed when becoming large in mounting hole aperture and again punch, secondly improve the installation fixing of valve shaft and the aperture of mounting hole is not allowed variable large.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
