Abstract

The utility model relates to a novel stop valve which mainly solves the problem that an existing stop valve is poor in sealing performance. A sealing ring is arranged at the side, opposite to the side with the handle, of a valve clack. An annular groove is formed in the side, opposite to the side with the valve clack, of the sealing ring. The inner side face and the outer side face of the sealing ring are respectively provided with a water stop ring. The stop valve is good in sealing performance, absolute sealing between the valve clack and a valve seat is ensured when the stop valve is closed, media in a valve body are kept stable, no leakage or fluctuation occurs, and normal working efficiency of the stop valve is ensured.

Description

A kind of stop valve
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of stop valve.
Background technique
Stop valve, is also pipe valve, is one of most popular a kind of valve, and why very popular it is, be due in switching process between sealing surface frictional force little, more durable, Lift is little, easy to manufacture, easy to maintenance, be not only applicable to mesolow, and be applicable to the feature of high pressure.Stop valve relies on valve rod pressure, valve clack sealing surface and sealing surface of seat are fitted tightly, organize media flow, but now on market most stop valves all to exist sealing bad, sealing surface of seat and valve clack sealing surface have the drawback of leakage, can cause very large inconvenience to use like this, cause damage, affect working efficiency.
Model utility content
In order to overcome the deficiency of background technique, the utility model provides a kind of novel cutoff valve, mainly solved the problem of existing stop valve poor sealing performance, the good seal performance of this stop valve, when valve closing, can guarantee the positive confinement between flap and valve seat, keep the media stabilize in valve body, do not leak, do not fluctuate, guaranteed valve normal operation efficiency.
The technological scheme that the utility model adopts is: a kind of stop valve, comprise valve body, flap, valve seat and valve rod, described stem exterior surface is provided with valve stem casing, one end of described valve rod is connected with handle, the other end of valve rod is arranged in valve body and is connected with flap, described flap is provided with seal ring with respect to the other end of handle, and described seal ring is provided with annular groove with respect to the opposite side of flap, and described seal ring inner side surface and outer side surface are respectively equipped with water stop ring.
By taking technique scheme, when valve closing, handle with sleeve, band ovable valve stem is exerted pressure to flap, with not revealing of forced seal face, described flap is provided with seal ring, the opposite side with respect to flap on seal ring is provided with annular groove, when in valve, medium rushes at seal ring, annular groove on seal ring has the effect of compensator or trimmer pressure, pressure rushes at the both sides of seal ring by annular groove, make the tightness of flap better, on seal ring, be also provided with water stop ring, with flap and valve body wall close contact more, also made better tightness between flap and valve seat, such design assurance flap can not washed open by medium, cause leakage, affect the workmanship of valve, improve the reliability of product.
The utility model is further set to: one end that described valve rod connects flap is provided with guide sleeve, and the upper end of described guide sleeve is provided with the through hole suitable with valve rod, and the lower end of described guide sleeve is provided with the groove suitable with flap.
By taking technique scheme, the setting of described guide sleeve, makes the connection between flap and valve rod more firm, also make the position of flap and valve seat junction surface more accurate, the effect that has guaranteed sealing, guarantees the normal working efficiency of stop valve, improves product reliability.
The utility model is further set to: valve seat is threaded with valve stem casing.
By taking technique scheme, described is threaded, simple in structure, makes easy for installation, install more firmly, stability is better, and described being threaded to removably connects, when breaking down, facilitate overhaul and maintenance, improved working efficiency.
The utility model is further set to: described water stop ring is made by fluorine rubber.
By taking technique scheme, described fluorine rubber material can be suitable for the needs of service valve under high temperature, selects oil resistant, and the material of corrosion resistance just can be suitable for fluid, and the valve of the media such as corrosivity needs.

Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further.
As shown in Figure 1, Figure 2 and Figure 3, a kind of stop valve, comprise valve body 1, flap 6, valve seat 2 and valve rod 3, described valve rod 3 outer surfaces are provided with valve stem casing 4, one end of described valve rod 3 is connected with handle 5, and the other end of valve rod 3 is arranged in valve body 1 and is connected with flap 6, and described flap 6 is provided with seal ring 7 with respect to the other end of handle 5, described seal ring 7 is provided with annular groove 8 with respect to the opposite side of flap 6, and described seal ring 7 inner side surfaces and outer side surface are respectively equipped with water stop ring 9.When valve closing, handle with sleeve 5, band ovable valve stem 3 is exerted pressure to flap 6, with not revealing of forced seal face, described flap 6 is provided with seal ring 7, bottom surface on seal ring 7 is provided with annular groove 8, when in valve, medium rushes at seal ring 7, annular groove 8 on seal ring 7 has the effect of compensator or trimmer pressure, pressure rushes at the both sides of seal ring 7 by annular groove 8, make the tightness of flap 6 better, on seal ring 7, be also provided with water stop ring 9, with flap 6 and valve body 1 wall close contact more, also made better tightness between flap 6 and valve seat 2, such design assurance flap 6 can not washed open by medium, cause leakage, affect the workmanship of valve, improve the reliability of product.
One end that described valve rod 3 connects flap 6 is provided with guide sleeve 10, and the upper end of described guide sleeve 10 is provided with the through hole 11 suitable with valve rod 3, and the lower end of described guide sleeve 10 is provided with the groove 12 suitable with flap 6.The setting of described guide sleeve 10, makes the connection between flap 6 and valve rod 3 more firm, also makes the position of flap 6 and valve seat 2 junction surfaces more accurate, has guaranteed the effect of sealing, guarantees the normal working efficiency of stop valve, improves product reliability.
Valve seat 2 is connected with valve rod 3 thread die cuttings.Described is threaded, simple in structure, makes easy for installationly, installs more firmly, and stability is better, and described being threaded to removably connects, and when breaking down, facilitates overhaul and maintenance, improved working efficiency.
