Abstract
The invention relates to a high-strength double ferrule stop valve. The valve comprises a valve body (1), a valve cover (2) and a valve rod (12), wherein a lock nut (3) is screwed on the valve cover (2); the valve rod (12) is connected with the valve body (1) and the valve cover (2) in an assembly mode; a hand wheel device is arranged at one end of the valve rod (12); the opening and closing of the valve is controlled by rotating a hand wheel (11) to adjust the position of the valve rod (12); and the valve cover (2) is provided with a sealing device. The valve is characterized in that: a double ferrule device is arranged at the two connectors of the valve body (1) respectively. Due to the structure, the stop valve has high connection strength, is safe and reliable, can be repeatedly exchanged and quickly assembled and disassembled, is particularly suitable for occasions that hot work and aloft work cannot be performed and construction conditions are inconvenient, and can greatly improve construction efficiency, effectively save cost, and improve economic benefit.
Description
Technical field
The present invention relates to the structure of stop valve, especially a kind of about at the employed high-strength pair of cutting ferrule tube type cut-off valve of petroleum chemical industry.
Background technique
The present employed stop valve of China's oil chemical industry, when requiring high temperature resistant, high pressure, high shake and high features such as corrosion resistance, cause is that the product technology performance of base material is reliable and stable inadequately with the stainless steel, the general stop valve connection of being adopted all adopts adapter welding type or socket weld formula to guarantee that product uses the requirement that will reach, but this dual mode can not got angry and the occasion of high-lift operation and execution conditions inconvenience, just bring no small economy, timeliness and safety problem to construction, construction cost increases greatly.And the also inconvenience of ten minutes of later maintenance maintenance, the Maintenance and Repair cost is higher equally.Part adopts the flared type valve to connect, though can reach construction and the easy requirement of Maintenance and Repair, shortcoming aspect high temperature resistant, high pressure, high shake and high corrosion resistance, working life is also shorter.And the domestic stop valve market that can reach usage requirement is all occupied by brand company of external a few family, has basically formed the monopolization situation.The domestic user that must use generally must buy the product of external import, not only cost an arm and a leg, and safeguard to change accessory also outbid to buy original paper producer equally.
Summary of the invention
Deficiency at the structure that has stop valve now existence in using or overhauling, the object of the present invention is to provide a kind of simple in structure, convenience quick for installation, high strength, the high-strength pair of FERRULETYPE stop valve that dual fail-safe resistance to pressure that double-sealing, two-restriction support admittedly and heat-resisting anti-seismic performance are good.
Technological scheme of the present invention realizes in the following manner: a kind of high-strength pair of FERRULETYPE stop valve comprises valve body, valve gap, valve rod; Locking nut is rotatably connected on the valve gap, and valve rod is connected with valve body and valve gap with assembling mode; Described handwheel devices is arranged on an end of valve rod, comes the switch of control valve by the position of rotation hand wheel regulating valve stem, and valve gap is provided with seal arrangement, it is characterized in that: described two ends of valve body access port is respectively equipped with two cutting ferrule devices.
Technological scheme of the present invention can also come further to realize in the following manner:
Above-mentioned cutting ferrule device is that two cutting ferrules are positioned over valve body and cutting ferrule nut and spin in the cavity of back formation.
Above-mentioned valve body is hard the cooperation with the junction plane of valve gap.
Above-mentioned seal arrangement be in the upper end of valve gap near the valve rod place be provided with locking nut, locking nut is rotatably connected on the valve gap, filler packing ring, filler, Gland all are placed in the valve gap epicoele, and control harmomegathus by spinning of gland nut and valve body, to reach the purpose that stop valve in use seals.
Above-mentioned handwheel devices is to be fastenedly connected with valve rod by nut, plain cushion and to be connected with valve body and valve gap with assembling mode by handwheel, label.
Adopt structure of the present invention, the join strength height of stop valve, safe and reliable, can repeat to exchange and fast assembling-disassembling.Two cutting ferrule devices at valve body two ends, played the dual fail-safe effect, seal arrangement has been realized high strength, the effect of double-sealing, particularly more suitable in the occasion that can not get angry with high-lift operation and execution conditions inconvenience, can greatly improve efficiency of construction, can save cost effectively again, increase economic efficiency.
The present invention is described in further detail below by accompanying drawing.

Embodiment
Known that by Fig. 1 high-strength pair of FERRULETYPE stop valve of present embodiment is made up of valve body 1, valve gap 2, handwheel devices, two cutting ferrule device and seal arrangement, valve body 1 and valve gap 2 connect in the mode of spinning; Locking nut 3 is rotatably connected on the valve gap 2; The filler packing ring 4 of seal arrangement, filler 5, Gland 6 all are placed in the epicoele of valve gap 2, and control harmomegathus by gland nut 7 and spinning of valve body 2, and guarantee the tightness of valve body in switching process; The handwheel 11 of handwheel devices, label 10 are fastenedly connected with valve 12 bars by nut 9, plain cushion 8; Valve rod 12 is connected with valve body 1 and valve gap 2 with assembling mode; The two ends 13 of valve body 1 are respectively equipped with two cutting ferrule devices, and two cutting ferrules 13 are positioned in the cavity of the back formation that spins between valve body 1 and the cutting ferrule nut 14.
Being known by Fig. 2, is the valve working theory structure schematic representation of present embodiment, and handwheel devices is the mode by rotation hand wheel, makes valve rod 12 reach the effect of control valve switch in valve gap 2 inner chamber liftings.
Know by Fig. 3, be the valve and access pipe fitting schematic diagram of present embodiment, two cutting ferrule devices are the locking of controlling two 13 pairs of access pipe fittings of cutting ferrule by the degree of tightness that cutting ferrule nut 14 and valve body 1 spin to finish and being connected of outer tube, valve body 1-1 is hard the cooperation with the junction plane of valve gap 2-1, the centre need not packing ring, and this also is a key point of the present invention.
