Abstract
The utility model relates to a stop valve with a threading connecting pipe joint. In order to reduce the numbers of parts connected with the stop valve, reduce manufacturing cost, and reduce the leakage opportunities of a passage system, the utility model provides a stop valve with a threading connecting pipe joint. The outlet end of the stop valve is changed into an outer thread from the original English pipe-type inner thread with a taper; the outlet end of the stop valve is provided with a sealing pad; the other side of the sealing pad is provided with a pipe joint; the pipe joint, the sealing pad, and the outlet end of the stop valve are tightly connected together by a tight nut.
Description
The utility model relates to a kind of stop valve of threaded connecting tube joint.
In fluid piping system, especially less than 16 kilograms per centimeter
2In the fluid piping system of pressure, the turnover oral-lateral of its instrument, instrument or its device all can't do without being provided with stop valve.The entrance end of known stop valve (no matter being taper stop valve, spherical stop valve or board-like stop valve) all adopts the tubular type internal thread made in Great Britain of band tapering to be connected with pipeline or other devices.The user is in order to repair or change the convenience of instrument, instrument or device, and great majority are equipped with by two pipe joints in the outlet port of stop valve, a sealing gasket and the pipe joint that is threaded that tightening nut is formed; The tubular type internal thread made in Great Britain of band tapering is generally also made at the two ends of this pipe joint that is threaded, and therefore must and be threaded at stop valve refills an outside thread free flow coupling between the pipe joint.So,, the outside thread free flow coupling to be arranged and by two pipe joints between instrument or the device, the pipe joint that is threaded that a sealing gasket and four parts of a tightening nut are formed at stop valve outlet end and instrument.The part that is connected in fluid piping system is many more, and its chance of sewing is also big more; Certainly, because part is many, make its cost just high more.Just there is this shortcoming in the set stop valve of above-mentioned pipe-line system.
The purpose of this utility model is to provide a kind of improved stop valve, makes the quantity of the connection minimizing part of its outlet end, reaches the reduction manufacture cost, reduces the chance that pipeline is sewed.
The utility model can be realized by following measure:
The stop valve of the threaded connecting tube joint of the utility model has valve body, valve, valve to cut down bar, seal ring, end cap, Sealing, gland nut, have the entrance point and the outlet end of the tubular type internal thread made in Great Britain of tapering, be characterized in: described outlet end is provided with the metric system outside thread, with the contacted sealing gasket of outlet end, with the contacted pipe joint of sealing gasket and by outlet end metric system outside thread pipe joint, sealing gasket and cut a valve and cut down the tightening nut that outlet end tightens together.
The stop valve of the threaded connecting tube joint of the utility model not only is applicable to the taper stop valve, also is applicable to spherical stop valve, also is applicable to board-like stop valve.
The stop valve of the threaded connecting tube joint of the utility model compared with prior art has following advantage:
1, reduces the number of spare parts that pipeline connects, reduced manufacture cost about 10%.
2, because therefore the minimizing of the number of spare parts that pipe-line system connected has also reduced the chance that pipe-line system is sewed.
Description of drawings is as follows:
Fig. 1 is a kind of structural representation of the stop valve of the threaded connecting tube joint of the utility model.
Now the utility model is described in further detail in conjunction with the accompanying drawings:
Among the figure 1 is the taper checking-valve body, 2 are taper stop valve (can certainly be designed to board-like checking-valve body and board-like stop valve or be designed to spherical checking-valve body and spherical stop valve), 3 is valve rod, 4 is seal ring, 5 is end cap, 6 is Sealing, 7 is gland nut, 8 is the entrance point of the tubular type internal thread made in Great Britain of band tapering, 9 is the externally threaded outlet end of metric system, and 10 is the sealing gasket made from leather, and 11 is pipe joint, this pipe joint one end has the tubular type internal thread of band tapering made in Great Britain, be connected with the pipeline of pipe-line system, the other end contacts with the leather seal pad, and 12 is tightening nut, the metric system outside thread that metric system internal thread by this tightening nut 12 matches with outlet end 9 is outlet end 9, sealing gasket 10 and pipe joint 11 linking together tightly.
Claims (2)
1, a kind of stop valve of threaded connecting tube joint, valve body 1, valve 2 are arranged, valve rod 3, seal ring 4, end cap 5, Sealing 6, gland nut 7, the entrance point 8 of the tubulose internal thread of band tapering and outlet end 9 constitute, it is characterized in that: described outlet end 9 is provided with the metric system outside thread, with the contacted sealing gasket 10 of outlet end, with sealing gasket 10 contacted pipe joints 11 and by outlet end metric system outside thread pipe joint 11, the tightening nut 12 that sealing gasket 10 and stop valve outlet end 9 tighten together.
2, the stop valve of threaded connecting tube joint according to claim 1 is characterized in that: described stop valve is applicable to the taper stop valve, spherical stop valve or board-like stop valve.
