At present, blocking device that tubular element uses and connection set generally branch are arranged, and earlier with the end shutoff of sealing blocking device with pipe, utilize connection set that two-section is coupled together then during use.Have the sealing blocking device now as shown in Figure 1: this device is to use in throttle valve body 06, utilize the rotation of pinch grip 01, make between compact heap 02 and the contiguous block 03 and separate, contiguous block 03 is promoted, jaw 04 provides a clamping force through lever, make the jaw 04 on the frock catch tubular member edge, and compact heap 02 is compressed sealing gasket 05, utilize the elasticity of sealing gasket 05 to seal by the Separating force of pinch grip 01 generation.Its deficiency is:
1, because jaw directly touches the tubular member of throttle valve body, makes it damage easily, produce the situation of colliding with and scratching;
2, wayward spinning force, power Da Yi produce the tubular member damage, and the little sealing effect of power can not reach requirement;
3, manually rotating handles is also relatively more difficult, has increased operating difficulties degree and operator's labor intensity.
Figure 2 shows that tubular connecting device at present commonly used, this connection set utilizes locking screw, clip to connect, be enclosed within screw rod, clip 08 on the flexible pipe 09 after and flexible pipe be assemblied in together on the tubular member 07, then with 08 urgent connection of clip.Its deficiency is:
1, the wearing and tearing of crosshead and screw thread are bigger in use for screw rod, clip, damage, change frequent easily;
If 2, screw rod is longer, inconvenient operation then, length expends time in.
The model utility content
For overcoming above-mentioned deficiency of the prior art, the purpose of this utility model has provided a kind of sealing shutoff connection set, this device will seal shutoff be connected integrated.
The utility model in order to realize the technological scheme that its technical purpose adopts is: a kind of sealing shutoff connection set, be plugged in the tubular member mouth, and comprise link, compressing member, end cover, handle, first elastic washer and second elastic washer;
It is conical that described compressing member integral body is, and its awl end mouth mask is on described tubular member mouth, and awl end arranged outside has projection, in the outlet port and the compressing member contacting point of tubular member second elastic washer is set;
Described link integral body is circular, is enclosed within described compressing member outside, is supported by the basolateral projection of described compressing member awl, and arranged outside has outside thread in the bottom of link;
Described end cover is circular, upside have with described link on the internal thread that is complementary of screw thread, the inside flange of following side bottom is provided with first elastic washer between the lower edge of end cover in-flanges and described compressing member;
Described handle comprises handle and long-armed, galianconism, a described long-armed end and described link are formed rotatable flexible connection, one end and the described compressing member of described galianconism are formed rotatable flexible connection, the described the other end and described handle three parts long-armed and galianconism are formed flexible connection, and described handle is the steelyard hook shape.
Further, in the sealing shutoff of above-mentioned tubular body and the connection set: described long-armed be to be connected with compressing member with link respectively with galianconism by bolt.
Further, in the sealing shutoff and connection set of above-mentioned tubular body: described first elastic washer and second elastic washer are rubber washer
The utility model beneficial effect is that utilization compresses the principle that expands the back with flexible packing ring and realized sealing shutoff and connection, and is relatively simple for structure, easily manufactured, and promoted the efficient of assembling, also reduces personnel labor intensity; Also avoid damaging tubular member in addition, improved the quality of tubular element.
Below with reference to drawings and Examples, the utility model is carried out comparatively detailed explanation.
Description of drawings
Fig. 1 is a tubulose sealing blocking device schematic representation of the prior art.
Fig. 2 is a tubular element connection set in the prior art.
Fig. 3 is the utility model embodiment 1 structural representation.
Fig. 4 is an A part enlarged view among Fig. 3.
Among the figure: 01, pinch grip, 02, compact heap, 03, contiguous block, 04, jaw, 05 sealing gasket, 06 throttle valve, 07, tubular member, 1, link, 2, compressing member, 3, end cover, 4, handle, 5, first elastic washer, 6, second elastic washer, 7, tubular member, 8, first is subjected to the arm of force, 9, second be subjected to the arm of force, 10, handle.
Embodiment
It is conical that compressing member 2 integral body are, and its awl end mouth mask is on 7 mouthfuls of described tubular members, and awl end arranged outside has projection, in the outlet port and compressing member 2 contacting points of tubular member 7 second elastic washer 6 is set; Compressing member 2 is a kind of farsighted cone shape much larger than diameter as required, convex edge outside bottom outside has.
Handle 4 comprises handle 10 and long-armed 9, galianconism 8, one end of long-armed (9) is formed rotatable flexible connection by bolt and link 1, one end of galianconism 8 is formed rotatable flexible connection by bolt and compressing member 2, long-armed 9 and the other end of galianconism 8 and handle (10) three parts form by bolt and flexibly connect, handle 10 is the steelyard hook shape
The present embodiment product has the following steps when using:
1, handle 4 loosens, and is exactly that handle does not stress, and makes whole device be relaxation state, and the present embodiment product is covered on the mouth of pipe of tubular member, closely is connected between tubular member 7 and first elastic washer 5 and second elastic washer 6.
2, press down handle 4, make the power that produces mutual extrusion between compressing member 2 and link 1 and the end cover 3, two packing ring pressurizeds produce and expand, with tubular member 7 outer side compressions, fix end cover 3 and link 1, compressing member 2 stressed pressing down, second elastic washer 6 is compressed, finish the sealing shutoff.
3, by adjusting the screw thread between the link 1 and the end cover 3, the adjustment with the decrement of flexible packing ring so just can have been realized in the gap between the compressing member 2 and first elastic washer 5, the shutoff degree of tubular member 7 has just realized controlled.
The working principle of present embodiment:
At first, this device is that integral body is enclosed within on the tubular member and after press down, handle is upwards pulled, pulling link 1 and end cover 3 move upward, and first elastic washer 5 moves upward thereupon, runs into after the compressing member 2, first elastic washer 5 is subjected to compression swelling, clamping tubular parts.First elastic washer 5 and tubular member 7 stressed generation frictional force fixed end cover 3 and link 1.Compressing member 2 just produces pulling force each other with end cover 3, and compressing member has been pressed in second elastic washer 6 on the tubular member openning inflexibly.The sealing of tubular element has just been realized by two elastic washers.
