One safety check, this safety check comprises a valve and a sealing gasket, and this valve one end is hubbed at week in this containing space, and the other end sets firmly sealing pad;

One control valve, this control valve comprises leader, an axis and a switching element, and this switching element is located between this fluid input and this runner of this valve inner, and this switching element provides a through hole, this axis one end radially wears this valve body periphery and sets firmly this switching element, and the other end sets firmly this handle; And

One valve gap, this valve gap is located at this opening ora terminalis with several retaining screw spiral shells;

By this, when promoting this handle, drive this axis and this switching element synchronous rotary, when this through hole is interconnected with this fluid input, this runner respectively, fluid sequentially flow through this fluid input, this through hole and this runner, and push this safety check open toward this fluid output output, when fluid is during by this fluid output reverse flow, fluid will promote this safety check is sealed on sealing ring sealing pad, block fluid and flow toward this fluid input, reach and control the double effects that fluid flows and blocks fluid countercurrent current.

Wherein, this control valve is a ball valve or a butterfly valve.

Wherein, sealing cushion cover is located at this valve, and a screw wears a pad and is screwed into this valve, and this pad, sealing pad and this valve spiral shell are integral admittedly.

Wherein, respectively this retaining screw sequentially wears this valve gap, a leak-proof washer and is screwed into this opening ora terminalis.

Wherein, sheathed one first leakage washer of this fluid input, sheathed one second leakage washer of this runner the other end, this first leakage washer, this second leakage washer are respectively and this switching element resilient abutment.

By said structure, the safety check that has valve body concurrently of the present utility model, has concurrently and controls the dual functions that fluid flows and prevents fluid countercurrent current in conjunction with control valve and safety check, and it need not increase by a linking pipeline, fit on simpler and easy with more save time; Control valve and safety check are combined into one, and overall volume is significantly dwindled, cost of material is also effectively saved in weight saving; Need not increase valve member and pipeline cohesive position, effectively reduce the risk of fluid leakage; By this opening, can inspect the associated component function situations such as safety check, and conveniently change spare part operation.

The technology that relevant the utility model adopts, means and effect thereof, hereby lift a preferred embodiment and coordinate after graphic being described in more detail in, and believes the above-mentioned object of the utility model, structure and feature, when can by one deeply and concrete understanding.
