Description
Technical field
The utility model relates to a kind of safety check, specifically a kind of Lift check valve.
Background technique
The Lift check valve used required for filling with on car air compressor at cement, existing Lift check valve such as notification number is that CN203413181U discloses a kind of Lift check valve, comprise the valve body of band valve pocket and be positioned at flap and the valve seat of valve pocket, flap connects the axis of guide, be provided with in valve pocket coordinate with the axis of guide lead micropore, lead micro-axle and be provided with piston away from the end of flap, this structure utilizes piston and piston cavity to slow down closing velocity before flap and valve seat close, thus the water hammer pressure produced when alleviating closedown, but this structure is relatively complicated; The jointing at this safety check two ends all have employed flange in addition, makes valve body heavier, and volume is large, and cost of production is higher, reduces the cost performance of product, and when connecting, the end of two side ducts all needs to arrange flange, adds unnecessary cost; The test of valve inner high strength in addition, thus has higher requirements to the stability of flap and valve base sealing, and wearing and tearing easily appear in the check valve seal of existing this structure, thus cause sealing not good.
Model utility content
The purpose of this utility model is to provide a kind of Lift check valve, the inlet end that valve body connects adopts flange, outlet end adopts female thread structure, make small product size more light and handy, arrange stainless steel Sealing in the bottom of flap, valve seat then arranges the seal groove that ring-type stainless steel Sealing coordinates simultaneously simultaneously, to be cooperatively interacted sealing by valve stainless steel Sealing, easy to wear and more durable in use, sealing effect is not better, improves the cost performance of product.
For achieving the above object by the following technical solutions:
A kind of Lift check valve, comprise the valve body and the flap be arranged in valve pocket and valve seat of being with valve pocket, flap connects the axis of guide, and the axis of guide is contained in the axocoel on valve pocket top, it is characterized in that: described valve body is wherein provided with flange in material feeding mouth one end, discharge port one end arranges internal thread.
The bottom of described flap is provided with stainless steel Sealing, the upper end-hole of valve seat offers seal groove, ring-type stainless steel Sealing is provided with in seal groove, the bottom of seal groove also has dovetail groove, the tip coordinated with dovetail groove is provided with bottom ring-type stainless steel Sealing, stainless steel Sealing and valve body are integrated through extruding to closely cooperate, stainless steel Sealing and ring-type stainless steel Sealing cooperatively interact and seal, described axocoel inwall arranges stainless steel seal ring, and the stainless steel seal ring axis of guide closely cooperates.
The utility model considers that existing Lift check valve two ends arrange flange and cause bulky, heavier, convert the flange of discharge port one end to internal thread, ensureing under the prerequisite that safety check is for convenience detach like this, make the volume of product compacter, attended operation is convenient; The structure of the utility model to valve seat and flap does corresponding amendment in addition, increase and established stainless steel Sealing, ring-type stainless steel Sealing and seal groove, contacted with each other by stainless steel Sealing, more durable in use, structure is simple, improves reliability and the cost performance of product.
Accompanying drawing explanation
Fig. 1 is internal structure schematic diagram of the present utility model;
Fig. 2 is the internal structure schematic diagram of the utility model valve body.
Embodiment
As shown in Figure 1, 2, a kind of Lift check valve, comprise the valve body 1 and the flap 12 be arranged in valve pocket 11 and valve seat 13 of being with valve pocket 11, flap 12 connects the axis of guide 14, the axis of guide 14 is contained in the axocoel 15 on valve pocket 11 top, described valve body 1 wherein material feeding mouth one end is provided with flange 2, and internal thread 3 is arranged in discharge port one end; In the bottom of described flap 12, stainless steel Sealing 6 is set, the upper end-hole of valve seat 13 offers seal groove 16, ring-type stainless steel Sealing 5 is provided with in seal groove 16, the bottom of seal groove 16 also has dovetail groove, the tip coordinated with dovetail groove is provided with bottom ring-type stainless steel Sealing 5, stainless steel Sealing 6 and ring-type stainless steel Sealing 5 cooperatively interact and seal, and described axocoel 15 inwall arranges stainless steel seal ring 17, and stainless steel seal ring 17 and the axis of guide 14 closely cooperate.
Two of valve body connecting heads are flange and internal thread by the utility model respectively, the Flange joint of flange and connecting tube, be convenient to demolition, after one end adopts Flange joint wherein, the other end just directly connects by internal thread, ensureing the volume that greatly can reduce valve body in the situation easily dismantled, weight reduction, save cost.
The utility model is provided with stainless steel Sealing 6 in the bottom of flap 12 in addition, the upper end-hole of valve seat 13 is provided with ring-type stainless steel Sealing 5, the bottom of seal groove 16 also has dovetail groove, the tip coordinated with angle is provided with bottom ring-type stainless steel Sealing 5, ring-type stainless steel Sealing 5 is connected to seal groove and cannot comes off by tip, the sealing of flap 12 and valve seat 13 coordinates realization by stainless steel Sealing 6 with ring-type stainless steel Sealing 5, stainless steel part wear resistance of seals intensity is better, better sealing effect can be ensured, more durable in use, thus improve the reliability of product.
