Abstract
A kind of integrated high pressure insulation safety check.Mainly solve existing check valve structure complexity, the problem of trouble is installed.It is characterized in that: comprise valve body, valve seat; Described valve body is integral type structure; Described valve seat is fixedly installed in valve body and is sealed and matched with valve interior wall; On described valve seat, be hingedly connected with rocking arm, described rocking arm is connected with flap; Described flap energy and valve base sealing.Its advantage is valve body to be designed to the integral structure without valve gap, makes structure simpler, by being integrated and assembling with valve body with rocking arm, flap design on valve seat, assembles also convenient.
Description
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of integrated high pressure insulation safety check.
Background technique
Safety check claims again check valve, one-way valve or check valve, and its effect is to ensure the medium directional flow in pipeline and do not cause the function flowing backwards.
Existing Swing check valve is all generally first valve seat, flap and rocking arm to be set in valve body, then is threaded connection and covers valve gap, not only complex structure, and trouble is installed.
Model utility content
In order to overcome the deficiency of background technique, the utility model provides integrated high pressure insulation safety check, solves existing check valve structure complexity, and the problem of trouble is installed.
The technological scheme that the utility model adopts: a kind of integrated high pressure insulation safety check, comprises valve body, valve seat; Described valve body is integral type structure; Described valve seat is fixedly installed in valve body and is sealed and matched with valve interior wall; On described valve seat, be hingedly connected with rocking arm, described rocking arm is connected with flap; Described flap energy and valve base sealing.
Described valve seat is provided with outside thread outward, and described valve seat is connected by screw-thread fit with valve body.
The outer ring of described valve seat one end is inclined-plane, and described valve seat and valve interior wall seal by inclined-plane.
Between described valve seat and flap, be also provided with one deck sealing gasket.
Described valve body is by stainless steel forging molding.
The beneficial effects of the utility model are: adopt above scheme, valve body is designed to the integral structure without valve gap, make structure simpler, by being integrated and assembling with valve body with rocking arm, flap design on valve seat, assemble also convenient.
Brief description of the drawings
Fig. 1 is the utility model example structure schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further: as shown in the figure, a kind of integrated high pressure insulation safety check, comprises valve body 1, valve seat 2;
Described valve body 1, by stainless steel forging molding, is integral type structure;
Described valve seat 2 is fixedly installed in valve body 1 and coordinates with valve body 1 inner wall sealing; On described valve seat 2, be hingedly connected with rocking arm 3, described rocking arm 3 is connected with flap 4; Described flap 4 can seal with valve seat 2.
Valve body 1 is designed to the integral structure without valve gap by this structure, make structure simpler, to on valve seat, be integrated again and assemble with valve body with rocking arm, flap design, assemble also convenient, valve body 1 is by stainless steel forging molding simultaneously, guarantee that it can work under hyperbaric environment, and heat insulation effect might as well.
Placement between valve seat 2 and valve body 1 has a lot, can be bolted, and can be also as shown in the figure, described valve seat 2 is connected by screw-thread fit with valve body 1, directly outside valve seat 2, is provided with outside thread 22, assembles convenient.
The outer ring of described valve seat 2 one end is inclined-plane 21, and described valve seat 2 seals by inclined-plane 21 with valve body 1 inwall, and valve seat 2 seals by inclined-plane firmly with valve body 1, and good sealing effect is simple in structure.
Between described valve seat 2 and flap 4, be also provided with one deck sealing gasket 5, can further strengthen its sealing effect.
