Abstract
The utility model discloses an injection valve special for switching on or off a channel for leaking a medium and a sealing injection in an injection type pressure sealing technology. The injection valve comprises a valve body and a bolt valve core, wherein contact surfaces between the valve body and the bolt valve core form a threaded pair seal which has very good self-locking and sealing functions; the main section of the valve body is a rectangle; the inlet end of the valve body has an internal tapered structure; and the rotating radius of the valve body during on-site installation is less than or equal to 16mm. The injection valve has the characteristics of small size, compact structure, low injection resistance, high sealing performance and low manufacturing cost, and is an updated and upgraded product. The injection valve is needed to be matched with an internal thread output injection gun.
Description
Technical field
The utility model relates to a kind of agent injecting type band means of press seals technology internal thread that is used for and exports the serial injection gun usefulness that is connected with leak stopping anchor clamps injecting hole, can switch on or off the special-purpose injecting valve of leaking medium and injecting sealant passage.
Background technique
In continization fluid commercial production field, the leakage problem of flowing medium remains the principal element that causes various serious accidents.The major technique means that are used at present the accident of stopping a leak both at home and abroad are to adopt agent injecting type band means of press seals technology, and the injecting valve then is to be used to cut off the special switch device that leaking medium and injecting sealant pass through in this technology.China begins extensive use agent injecting type band means of press seals technology from the mid-80; But the injecting valve is continued to use the traditional pattern of a kind of tap structure that Britain Fo Man Knite Incf. (FURMANITE) provides always; The bolt that exactly likes an edge length of this injecting valve, entry end is an internal thread, outlet end is an outside thread; The centre is a cock spool, and sealing relies on the machining accuracy of spool and valve body inner bore to realize.Feel in the practical application that the deficiency of this type of injecting valve is; Poor sealing, reason are that it adopts tap structure, rely on a locking nut fastening; Be difficult to accomplish the precision seal request; During operation, particularly when the handle high voltages leaking medium, injecting sealant occurs excessive through the binding site of be everlasting valve body and cock; The physical dimension of injecting valve is excessive in addition, and when some narrow space operations, inconvenience connects even can't connect, need be by other means; Because there is certain unreasonable factor in the structural design of injecting valve, the injecting resistance is bigger, and necessity that its overall structure is designed is again arranged.
Summary of the invention
The utility model provides a kind of injecting valve; This device mainly is made up of valve body and bolt spool two-part, and the valve body of injecting valve and bolt spool all adopt the metric fine thread sealing, clockwise the bolt spool is screwed under the tightest location status during making; Machinery drills through the valve bolt core; Form passage, and the screw pair sealability of injecting valve just in time is in the optimum state at this moment, sealing obviously improves; Valve body is a rectangular configuration, and input and output screw thread are outside thread, and overall dimensions reduces, and the required turning radius of the on-the-spot installation of injecting valve also obviously reduces.
The utility model is to realize through following scheme: a kind of injecting valve, it comprises valve body (1) bolt spool (2).The valve body of injecting valve and bolt spool all adopt the metric fine thread sealing, and in production process, the bolt spool are screwed under the tightest location status; Machinery drills through the valve bolt core; Form passage, and the sealability of injecting valve just in time is in the optimum state at this moment, sealing obviously improves; Valve body (1) entry end is a conical structure, can reduce the circulating resistance of injecting sealant effectively; Valve body (1) entry end is the metric system outside thread of M16, M18 or M20, can be connected use with all kinds of internal thread output injection guns, and its outlet end is the metric system outside thread of M12 or M10, can be connected with the injecting hole of various leak stopping anchor clamps, forms the shortest injecting passage; One transversal slotting is arranged at the top of bolt spool (2), is mainly used in the direction of indication injecting opening of valves.
Characteristics of the present invention are; The cock of the existing injecting valve that uses is nut check formula structure; Change the thread seal structure into, when improving injecting valve seal performance, the bolt spool itself has good self-locking property; Saved locking nut in the existing injecting valve, fabricating cost also greatly reduces simultaneously; The path of existing injecting valve is to wait gauge structure, and the utility model injecting valve inlet end is a conical structure, can reduce the circulating resistance of injecting sealant effectively; The main cross section of the existing injecting valve that uses is the hex head bolt formula, and the installation turning radius is 22～28mm, and the main cross section of injecting valve of the present invention is a rectangle, turning radius is installed only needs 16mm, and export the supporting use of injection gun with advanced person's internal thread.That its characteristics can be summarized as is in light weight, compact structure, injecting resistance are little, good airproof performance and low preparation cost, is the Updated product of injecting valve.
Described valve body and bolt spool adopt the fine thread sealing of metric system M10.
Described valve body (1) entry end is the inner conical structure, helps injecting sealant and passes through, and it is obvious to reduce injecting resistance effect.
Described entry end is the metric system outside thread of M16, M18 or M20, and its outlet end is the metric system outside thread of M12 or M10.
The fluting of the top hex head bolt head of described bolt spool (2) is mainly used in the opening direction of indicating the injecting valve.
Description of drawings
Fig. 1 is the structural representation of the utility model.
In the accompanying drawing: valve body (1), bolt spool (2)
Embodiment
Injecting valve shown in the drawings, it comprises valve body (1), bolt spool (2).The injecting valve must with injecting instrument and the supporting use of leak stopping anchor clamps in the agent injecting type band means of press seals technology, only establish two kinds of working staties of standard-sized sheet or complete shut-down in the use, belong to and be prone to consumption rapid wear device, large usage quantity.
Being skillful in those skilled in the art person it is understandable that; Except that above-mentioned specific description; The embodiment of the utility model is illustrative rather than restrictive, and under the situation that does not break away from the spirit and scope of the present invention, all variations and modification are all within scope of the present invention.
