Because in the foam gun use, the pressure that ball sealer 3` is subjected in the adapter 5` is directly followed the how much relevant of the interior blowing agent storage of foamed glue tank body, volute spring 4` decrement was also big when pressure was big.When the foamed glue jar is the new bottle in Kaifeng just, its blowing agent that charges into adapter 5` is also maximum to the pressure that ball sealer 3` produces during use, at this moment the amount of contraction of volute spring 4` is also maximum, after being easy to cause volute spring 4` to be compressed to the limit, ball sealer 3` blocks the circular hole in the screw 1` and causes that blowing agent can not normally charge in the foam gun rifle body 6` chamber, causes foam gun normally not use.In the actual use of foam gun, through regular meeting similar incidents take place.
Moreover, the depth of thread of the adapter 5` that matches with screw 1` directly has influence on the amount of contraction of volute spring 4`, depth of thread processing herein is in case the volute spring 4` decrement that just may cause bigger than normal slightly is excessive and make volute spring elastic force become big, the spring pressure that causes ball sealer 3` to receive helps to the pressure of its generation greater than the foaming in the foamed glue jar, cause the adapter obstruction and cause adapter to be scrapped, production cost strengthens.
Summary of the invention
For overcoming spray gun in the prior art because of pressing higher easy generation shutoff, defective that difficulty of processing is big in the foam tank, the purpose of this utility model is to propose to limit the maximum compressibility of volute spring, avoid ball sealer to stop up the foam gun adapter that portals, and metallic screw replaced by moulding, the moulding dimensionally stable need not back processing, and the corresponding adapter manufacturing procedure that makes reduces, the scrappage of parts reduces, and has shortened the production cycle of product.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of foam gun adapter, comprise adaptor body, ball sealer and to the volute spring of ball sealer roof pressure, adaptor body has inner chamber, the interior copper insert that screws in of fluid course that it is characterized in that inner chamber, be provided with lining in the copper insert, lining is between sealing gasket and gland, copper insert upper end and inner chamber top end face lean, the runner that copper insert has corresponding inlet opening and communicates with fluid course at the liquid inlet of fluid course, ball sealer places in the copper insert, be provided with seal washer between the inner face of ball sealer and copper insert, one end roof pressure ball sealer lower end of volute spring, other end roof pressure is being fixed on the gland of copper insert, hollow forms runner in the gland, and the upper end has strides the projection taper muscle of establishing on it, is fan-shaped opening between the taper muscle, the gland runner communicates with the runner of copper insert by fan-shaped opening, and the vertex of a cone of taper muscle and preloading spring is positioned at same straight line.Further, also be provided with lining in the described copper insert, lining is between seal washer and gland.
It is recessed that described seal washer has a sphere towards a side of ball sealer, and its radius is consistent with the ball sealer radius.
Foam gun adapter compared to existing technology, the utility model beneficial effect is:
(1) because the pyramidal projections of gland has limited the maximum axial of ball sealer moves, an end of volute spring is pressed on the taper muscle base plane of (also can claim bullet), the maximum compressibility of control volute spring, the hidden danger of effectively having avoided adapter to stop up.
(2) because the flow of adapter fluid course is to be decided by the awl end face of gland and the distance of ball sealer, after in case distance is between the two determined, the maximum stream flow of blowing agent has also just been determined in the adapter, the foamed glue that the blowing agent storage is different is canned go in the adapter after, it flows into the endoceliac flow of rifle through adapter can reach consistent substantially.
(3) because gland tapering and Packing spring tapering are suitable, the spring stress distortion is even, and it can produce forward thrust clocklike all the time to the seal washer circle, and seal washer circle stress deformation is even, can well reach sealing effectiveness.
(4) adopt plastic material to make lining and gland, dimensionally stable behind the plastic product forming, adaptor body inner chamber have reduced the scrappage of spare and accessory parts by the work that matches of a plurality of parts, have shortened the production cycle of product.
