Abstract

The invention relates to a rotary control type stop valve which comprises a valve body, a valve rod, an air inlet connector and an air outlet connector. A valve clack is arranged at the bottom of the valve rod, the air inlet connector extends into the valve body and is provided with a sealing seat, the sealing seat is vertically arranged upwards, a step groove is formed in the upper surface of the sealing seat, and a protrusion matched with the groove is arranged on the lower end face of the valve clack. The rotary control type stop valve with the technical scheme can effectively stop medium flowing, saves labor and is convenient to use.

Description

Rotation controlled stop valve
Technical field
The present invention relates to a kind of valve, be specifically related to a kind of rotation controlled stop valve.
Background technique
Stop valve is a kind of valve that switches on or off pipeline closure completely, be widely used in industry, pilot line medium circulation in sphere of life, conventionally stop valve is by rotation hand wheel, make valve rod increase and decline drive flap do perpendicular to MEDIA FLOW to straight-line displacement reach the object of keying, at present, the flap of stop valve inner sealing surface and stem bottom rotatably compresses closure by handwheel, need people for the enough large power that screws is provided, by flap and valve body sealing surface compacting laminating, when rotation hand wheel is controlled stop valve, often waste time and energy, and be difficult to medium in pipeline thoroughly to disconnect, to user, make troubles.
Summary of the invention
The object of the present invention is to provide and a kind ofly can effectively end medium circulation, rotation controlled stop valve laborsaving and easy to use.
To achieve these goals, the invention provides a kind of rotation controlled stop valve, comprise valve body, valve rod, air input joint and air outlet adapter, described stem bottom is provided with flap, described air input joint extends to and in valve body, is provided with sealing seat, described sealing seat arranges straight up, and described sealing seat upper surface is provided with stair-stepping groove, and described flap lower end surface is provided with groove and carves mutually the projection of closing.
Adopt the rotation controlled stop valve of technique scheme to have following advantage: because the flap lower surface of stem bottom setting is provided with stair-stepping projection, carve and close mutually with the groove in stop valve, user is when rotation hand wheel, flap is combined tightr with valve body, better tightness, medium in pipeline is played to the effect of damming, user in use, more convenient laborsaving, because flap lower end surface is provided with stair-stepping projection, increased compression area, slowed down flap local compression degree, make the use of stop valve more lasting, extended the working life of stop valve.
As preferred version, consider that user, when rotation hand wheel operation, slows down hand pressure, described valve stem tip is provided with the handwheel with sheath, and described sheath is that plastic material is socketed on handwheel wheel limit.
As preferred version, consider that flap moves downward in process, flap can compress fully with sealing seat, and described sealing seat both sides are provided with packing groove.
Accompanying drawing explanation
Fig. 1 is rotation controlled stop valve embodiment's of the present invention structural representation;
Wherein: 1, valve body, 2, valve rod, 3, air input joint, 4, air outlet adapter, 5, flap, 6, sealing seat, 7, projection, 8, handwheel, 9, sheath, 10, packing groove.
embodiment
Below in conjunction with drawings and Examples, technical solution of the present invention is further illustrated:
As shown in Figure 1, the invention provides a kind of rotation controlled stop valve, comprise valve body 1, valve rod 2, air input joint 3 and air outlet adapter 4, described valve rod 2 bottoms are provided with flap 5, described air input joint 3 extends to and in valve body 1, is provided with sealing seat 6, described sealing seat 6 arranges straight up, and described sealing seat 6 upper surfaces are provided with stair-stepping groove, and described flap 5 lower end surfaces are provided with groove and carve mutually the projection 7 of closing; Consider that user, when rotation hand wheel 8 operation, slows down hand pressure, described valve rod 2 tops are provided with the handwheel 8 with sheath 9, and described sheath 9 is taken turns on limit for plastic material is socketed in handwheel 8; As preferred version, consider that flap 5 moves downward in process, flap 5 can compress fully with sealing seat 6, and described sealing seat 6 both sides are provided with packing groove 10.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; do not departing under the prerequisite of structure of the present invention; can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.

Claims (3)

1. a rotation controlled stop valve, comprise valve body, valve rod, air input joint and air outlet adapter, described stem bottom is provided with flap, it is characterized in that: described air input joint extends to and in valve body, is provided with sealing seat, described sealing seat arranges straight up, described sealing seat upper surface is provided with stair-stepping groove, and described flap lower end surface is provided with groove and carves mutually the projection of closing.
