Abstract
The utility model discloses a meter pre-gate valve comprising a valve body and ports at the left side and the right side of the valve body, wherein the port at the right side is internally plugged with a telescopic copper bushing which is connected with the port at the right side by a sealing nut; a sealing structure is also arranged between the sealing nut and the port at the right side; and the tail end of the telescopic copper bushing is connected with a connecting nut connected with a water meter port, and the outer side of the head part of the telescopic copper bushing is provided with a chamfer angle. Due to the adoption of the technical scheme, the telescopic copper bushing can slide in the cavity at the right end of the valve body and fastened and sealed, so the water meter can be replaced only by disassembling the water meter in needs, thus realizing the effects of short connection distance, simple installation and good sealing property and reliability. Due to the chamfer angle outside the head part of the telescopic copper bushing, the meter pre-gate valve is convenient for the assembly between the telescopic copper bushing and the inner bore of the valve body.
Description
Technical field
The utility model relates to a kind of preceding gate valve that uses of tap water supply water meter that is applied to, and is mainly used in the connection of water supply water meter, pipeline, belongs to valve field.
Background technique
At present, in pipelines such as tap water connect, the water meter early gate is connected with water meter all to be needed to connect by watermeter connector or loose joint, thereby connect apart from long, installation more complicated, when water meter need be changed, need simultaneously and will can carry out after the package unit dismounting, installation and maintenance are inconvenience very, and the sealing of this structure is also good inadequately, leaks easily.
The model utility content
Technical problem to be solved in the utility model just provides a kind of connection distance weak point, installs simply, the preceding gate valve of the table that sealing reliability is good.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: gate valve before the table, comprise valve body and valve body left and right sides port, it is characterized in that: described right side port interpolation connects a flexible copper sheathing, flexible copper sheathing is connected with described right side port by a sealing nut, also be provided with sealing configuration between described sealing nut and described right side port, described flexible copper sheathing tail end connects an attaching nut who is connected with the water meter port, and chamfering is established in the described flexible copper sheathing head outside.
As preferably, be provided with rectangular seal between described flexible copper sheathing outer end end face and water meter port, described flexible copper sheathing outer end end face is provided with the V-ring groove.Rectangular seal is used for installing the end face seal of copper sheathing end face and water meter, and flexible copper sheathing sealing is more reliable when making piping erection.
As preferably, the described flexible copper sheathing 0～15mm that can in valve body right-hand member cavity, slide.
The utility model has been owing to adopted technique scheme, flexible copper sheathing can slide in valve body right-hand member cavity and fit sealing, thereby only needs when water meter need be changed the water meter dismounting, realize connecting that distance is short, installation simply, sealing reliability is good.Because the flexible copper sheathing head outside is 15 ° of chamferings, the assembling of convenient flexible copper sheathing and valve body inner bore.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is flexible copper sheathing structural representation;
Fig. 3 is an I place enlarged view among Fig. 2;
Fig. 4 is the structural representation of valve body right side port and attaching nut joint.
Embodiment
As shown in Figures 1 to 4, be installed in the embodiment of gate valve before the table before the water meter for the utility model is a kind of, valve gap 2, the flashboard that comprises valve body 1, valve body upper end is positioned at body cavity, valve rod 6 one ends connect flashboard 3, it is outer and connect handwheel 10 that the other end stretches out valve gap, handwheel is fastening by hexagon nut 12, also be provided with nameplate 11 on the handwheel, be provided with between valve gap and valve body upper end-hole to be provided with between mouth sealing ring 4, valve gap inboard and valve rod between locking nut 5, valve gap upper end and valve rod and compress and seal by stuffing box packing 7, gland nut 8, packing press ring 9.
Gate valve also comprises valve body left and right sides port before the described table, described right side port interpolation connects a flexible copper sheathing 16, flexible copper sheathing is connected with described right side port by a sealing nut 13, also be provided with sealing configuration between described sealing nut and described right side port, described flexible copper sheathing tail end connects an attaching nut 17 who is connected with the water meter port, and the described flexible copper sheathing head outside is 15 ° of chamferings 24.Be provided with rectangular seal 18 between described flexible copper sheathing outer end end face and water meter port, described flexible copper sheathing outer end end face is provided with V-ring groove 23.Described sealing configuration comprises the O-ring seals 14 that is socketed on the described flexible copper sheathing external diameter, and back-up ring pad 19 is established in the O-ring seals left side, and copper packing 15 is established on the right side.Described valve body right side port is provided with chamfering 22 in back-up ring step 21 and 15 °, and described back-up ring pad is located on the back-up ring step, and described O-ring seals is located at chamfering 22 positions in 15 °.Adjacent chamfering 24 inner sides are provided with draw-in groove 25 on the described flexible copper sheathing head outer diameter, are provided with a snap ring 20 in the draw-in groove.The flexible copper sheathing 16 0～15mm that can in valve body 1 right-hand member cavity, slide.
When installing and using, elder generation is connected valve, water meter respectively with pipeline, unscrew sealing nut 13 then, places rectangular seal 18, and attaching nut 17 is threaded with tap water water meter port, again sealing nut 13 is tightened to not leak to get final product.Otherwise in dismounting during water meter, gate valve closed unclamp sealing nut 13 and attaching nut 17, the copper sheathing 16 that will stretch pushes back in the valve body stomidium, can change water meter easily.
