Description
Technical field
The utility model relates to a kind of valve, particularly the adjustable safety check of a kind of pillar.
Background technique
Safety check belongs to a kind of automatic valve, and its Main Function is to prevent that medium from flowing backwards, preventing pump and drive motor reversion, and the releasing of vessel media.
Traditional pillar safety check mainly by valve body, be located at the runner on valve body, one end of runner is import, the other end is outlet, in runner, be provided with flap, the valve seat sealing with flap between flap and runner import, flap is with respect to being provided with sleeve with the other end of valve seat gluing, sealing one end, and sleeve is provided with the valve rod being connected with flap, between flap and sleeve, is provided with and compresses spring; Conventionally adopt before flap and valve seat sealing gasket to implement sealing, yet flap sealing gasket on it in running can rub with valve seat often, long use can cause sealing gasket to leak.
Summary of the invention
The deficiency existing for prior art, the utility model provides a kind of good airproof performance, the adjustable safety check of antifrictional pillar.
For achieving the above object, the utility model provides following technological scheme: the adjustable safety check of a kind of pillar, include valve body, be located at the runner on valve body, one end of runner is import, the other end is outlet, in runner, be provided with flap, the valve seat sealing with flap between flap and runner import, flap is with respect to being provided with sleeve with the other end of valve seat gluing, sealing one end, sleeve is provided with the valve rod being connected with flap, between flap and sleeve, be provided with and compress spring, between flap and valve seat, be provided with Sealing, it is characterized in that: the gluing, sealing place of described flap and valve seat is provided with hard sealing block, valve seat is provided with the hard sealing projection with this hard sealing block gluing, sealing, hard sealing projection is provided with several and the seal convexity of hard sealing block gluing, sealing.
Adopt technique scheme, flap is provided with hard sealing block, valve seat is provided with the hard sealing projection with hard sealing block gluing, sealing, after arranging like this, Sealing between flap and valve seat can too fast not the wearing and tearing due to the action of flap, the setting that firmly seals seal convexity on projection can make firmly to seal between projection and hard sealing block and form Multi-point sealing, has guaranteed sealing.
The utility model is further set to: between sleeve and valve rod, be provided with valve rod locating piece, this locating piece is the latch through sleeve and valve rod socket connection, is evenly equipped with the adjustment hole that several are pegged graft for latch on valve rod.
Adopt technique scheme, after arranging like this, valve rod can be implemented the adjusting to Compress Spring spring force by the adjustment hole on it, with this, regulates the compressive force to flap, controls the pressure of the medium being entered by runner import.
The utility model is further set to: flap is provided with the laminating end place of hard sealing block the draw-in groove of establishing for hard sealing block card, and hard sealing block is provided with the card convex with this draw-in groove adaptation.
Adopt technique scheme, after arranging like this, flap with firmly between sealing block, be connected more compactly, can prevent that hard sealing block and flap from coming off, and guaranteed the sealing of flap and valve seat.
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment's structural representation;
Fig. 2 is the I portion enlarged diagram of Fig. 1.
Embodiment
As Fig. 1, the adjustable safety check of a kind of pillar shown in Fig. 2, include valve body 1, be located at the runner 11 on valve body 1, runner 11 one end is import 12, the other end is outlet 13, in runner 11, be provided with flap 2, the valve seat 3 sealing with flap 2 between flap 2 and runner 11 imports 12, flap 2 is with respect to being provided with sleeve 4 with the other end of valve seat 3 gluing, sealing one end, sleeve 4 is provided with the valve rod 5 being connected with flap 2, between flap 2 and sleeve 4, be provided with and compress spring 6, between flap 2 and valve seat 3, be provided with Sealing 7, Sealing 7 includes the hard sealing block 71 that the gluing, sealing place of flap 2 and valve seat 3 is provided with, valve seat 3 is provided with the hard sealing projection 72 with these hard sealing block 71 gluing, sealings, hard sealing projection 72 is provided with several and the seal convexity 721 of hard sealing block 71 gluing, sealings.In such scheme, flap 2 is provided with hard sealing block 71, valve seat 3 is provided with the hard sealing projection 72 with hard sealing block 71 gluing, sealings, after arranging like this, Sealing 7 between flap 2 and valve seat 3 can too fast not the wearing and tearing due to the action of flap 2, the setting that firmly seals seal convexity 721 on projection 72 can make firmly to seal between projection 721 and hard sealing block 71 and form Multi-point sealing, has guaranteed sealing.
