Description
Technical field
The utility model relates to a kind of valve, particularly a kind of novel stop valve.
Background technique
Angle valve is exactly Angle Stop valves, and outlet becomes 90 degree of right angles with import, in the laying of tap water pipe line, is usually used in sanitary ware and connects, out outlet in switching.At present, the angle valve on market on tap water supply pipeline generally adopts ceramic valve core, but the angle valve that ceramic valve core is housed can produce a large amount of incrustation scale when not using for a long time, and incrustation scale can cause the blocking of spool, causes angle valve not open and close.Further, traditional ceramic valve core average wall thickness only has 0.8-1mm, has grown service time and will produce fracture, and the phenomenon that the sealing surface that the inner may occur after long-term use can wear and tear, sealing is poor.
Model utility content
The purpose of this utility model provides to solve above-mentioned the deficiencies in the prior art a kind of novel stop valve that a kind of long service life, structure are simple, can realize long-term sealing.
To achieve these goals, a kind of novel stop valve designed by the utility model, comprise valve rod, there is the valve body of passage, be arranged on the Xia Fa road of valve body lower end and be arranged on the valve gap of valve body upper end, valve rod one end to be placed in valve body and to be connected with flap, the other end is connected with transmission device, it is characterized in that: in described valve body, be provided with the tilting valve seat that valve base sealing overlaps and is arranged on valve base sealing set upper side place, above-mentioned flap lower end is provided with flap gland nut and sealing surface, sealing face is the conical surface, described sealing surface, tilting valve seat adopts cobalt-chromium-tungsten alloy material to make, above-mentioned sealing surface forms through grinding.
Preferably, described valve interior wall is also provided with valve body lining.
Preferably, between described valve rod and flap, gland is installed.
Preferably, described transmission device comprises many rotary types electric actuator or handwheel.
A kind of novel stop valve that the utility model obtains, (1), sealing surface are not easy to wear, scrape resistence, good seal performance, long service life.(2), particular/special requirement, this valve flap cover and valve seat entirety adopt CoCrW (cobalt-chromium-tungsten alloy) material, sealing surface is through grinding, processing difficulties, sealing surface processing is meticulous, there is the features such as hardness is high, scrape resistence, wearability are superior, abrasion-resistance is strong, even if use under the high temperature of red heat, also can keep these features.(3), when opening and closing flap stroke is less, and opening and closing time is shorter, and valve height is less.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: valve body 1, Xia Fa road 2, valve gap 3, flap 4, valve base sealing cover 5, tilting valve seat 6, flap gland nut 7, sealing surface 8, valve body lining 9, valve rod 10, gland 11.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment:
As shown in Figure 1, a kind of novel stop valve that the present embodiment provides, comprise valve rod 10, there is the valve body 1 of passage, be arranged on the Xia Fa road 2 of valve body lower end and be arranged on the valve gap 3 of valve body upper end, valve rod 10 one end to be placed in valve body and to be connected with flap 4, the other end is connected with transmission device (not shown), transmission device is arranged on valve rod 10 upper end, valve base sealing cover 5 and the tilting valve seat 6 being arranged on valve base sealing set upper side place is provided with in described valve body, above-mentioned flap lower end is provided with flap gland nut 7 and sealing surface 8, sealing face 8 is in the conical surface, described sealing surface 8, tilting valve seat 6 adopts cobalt-chromium-tungsten alloy material to make, above-mentioned sealing surface 8 forms through grinding, sealing surface 8 is not easy to wear, scrape resistence, good seal performance, long service life.(2), particular/special requirement, this valve flap cover and valve seat entirety adopt CoCrW (cobalt-chromium-tungsten alloy) material, sealing surface is through grinding, processing difficulties, sealing surface processing is meticulous, there is the features such as hardness is high, scrape resistence, wearability are superior, abrasion-resistance is strong, even if use under the high temperature of red heat, also can keep these features.
Further, described valve interior wall is also provided with valve body lining 9.
Further, gland 11 is installed between described valve rod and flap, better can plays and fixedly prevent from loosening.
Further, described transmission device comprises many rotary types electric actuator or handwheel, and when this valve uses handwheel to close, handwheel rotates (handwheel is provided with mark) in the direction of the clock; Electronicly do not need manual control.
A kind of novel stop valve that the utility model obtains, during keying, flap stroke is less, and opening and closing time is shorter, and valve height is less, and sealing surface is the conical surface, and flap is along the center line moving linearly of fluid.When medium flows into below flap, the sealing force applied must be equal to or greater than necessary specific pressure and medium active force sum upwards that sealing surface produces.Its advantage be surface of contact closely sealed time without friction, when making sealing surface circularity be out of shape due to pipe stress, also can not affect the performance of sealing surface.When this valve drives by the dynamic device of liquid (vapour), valve rod is made to be elevated and to drive flap work perpendicular to the straight-line displacement of fluid to reach keying object.
Sealing surface adopts overall CoCrW material removal to process, and strengthens sealability and improves working life.
For the utility model person of an ordinary skill in the technical field; without departing from the concept of the premise utility; its framework form can be flexible and changeable; just make some simple deduction or replace, all should be considered as belonging to the scope of patent protection that claims of being submitted to by the utility model are determined.
