The socket locking structure also comprises a pressing ring connected with the end part of the medium inlet pipe section and/or the end part of the outlet pipe section, wherein the pressing ring comprises a pressing cover, and a clamping ring is arranged on the pressing cover; a clamping groove is arranged between the pressing cover and the clamping ring, and bayonets are arranged on the clamping ring along the circumferential direction and correspond to the locking lug boss; and a wedge structure is arranged between the contact surfaces of the clamping ring and the locking lug boss, and a connecting hole is arranged on the pressing cover. The utility model can prevent a pipeline from separating from a valve, has simple structure, convenient installation, no welding or bolt fixing, better corrosion resistance and the like, is suitable for the filed of water supply.
Description
Technical field
The utility model belongs to the water supply field, is specifically related to a kind of socket joint locking mechanism that is used for socket joint gate valve and socket pipe member.
Background technique
At present, the valve on the water supply network is embedded in underground, and the application of spigot and socket type pipeline and valve is extensive gradually, but common spigot and socket type elastic sluice valve with wedge-shaped sealing face, in use, excessive or other reason as pressure, pipeline can break away from from valve gradually, causes valve leak.
Summary of the invention
It is a kind of simple in structure that the purpose of this utility model is to provide, and the socket joint locking mechanism that is used for socket joint gate valve and socket pipe member easy for installation is to address the above problem.
The technical solution of the utility model is: a kind of socket joint locking mechanism that is used for socket joint gate valve and socket pipe member, it comprises that end face is the medium inlet section and/or the outlet pipe section of bell and spigot frame, medium inlet section and/or outlet pipe section inwall are provided with seal arrangement, the end face of described medium inlet section and/or outlet pipe section along the circumferential direction is provided with the locking boss, it also comprises the trim ring that is connected with medium inlet section end and/or outlet pipe section end, trim ring comprises gland, gland is provided with snap ring, is provided with draw-in groove between gland and the snap ring; Snap ring along the circumferential direction is provided with bayonet socket, and bayonet socket is corresponding with the locking boss; Between the surface of contact of snap ring and locking boss is wedge-shaped structure, offers attachment hole on the gland.
Described locking boss is the boss along thickness direction band gradient.
Described connection hole is provided with the fastening pipe box of wedge shape.
Described trim ring outer wall is provided with the installation base of being convenient to its installation.
Because the utility model adopts the locking boss structure, has avoided in use excessive or other reason as pressure, pipeline can break away from from valve gradually, causes the situation of valve leak, and simple in structure, easy for installation, need not welding or bolt, anti-corrosive properties are better.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
As Fig. 1, a kind of socket joint locking mechanism that is used for socket joint gate valve and socket pipe member shown in 2 and 6, it comprises that end face is the medium inlet section 10 and/or the outlet pipe section 2 of bell and spigot frame, medium inlet section 10 and/or outlet pipe section 2 inwalls are provided with seal arrangement 3, the end face of described medium inlet section 10 and/or outlet pipe section 2 along the circumferential direction is provided with locking boss 6, and this locking boss 6 is arranged on the end face of the medium inlet section 10 of valve body 1 and/or outlet pipe section 2, it also comprises the trim ring that is connected with medium inlet section 10 ends and/or outlet pipe section 2 ends, trim ring comprises gland 5, gland 5 is provided with snap ring 4, is provided with draw-in groove 7 between gland 5 and the snap ring 4.
As shown in Figure 3, above-mentioned locking boss 6 is the boss along thickness direction band gradient, and promptly a plane and b plane are not parallel.
Shown in Figure 4 and 5, above-mentioned snap ring 4 along the circumferential direction is provided with bayonet socket 11, and bayonet socket 11 is corresponding with locking boss 6; Between the surface of contact of snap ring 4 and locking boss 6 is wedge-shaped structure, and described locking boss 6 is the boss along thickness direction band gradient, offers attachment hole 12 on the gland 5.These attachment hole 12 places are provided with the fastening pipe box 8 of wedge shape.Described trim ring outer wall is provided with the installation base 13 of being convenient to its installation.
Present embodiment is that locking boss 6 is arranged on the end face of the medium inlet section 10 of valve body 1 and/or outlet pipe section 2, certainly also the locking boss 6 of this socket joint locking mechanism can be located on the end face of the medium inlet section 10 of pipeline 9 and/or outlet pipe section 2, other parts are corresponding to be arranged.
When the utility model uses, only need earlier seal arrangement 3 to be put into the medium inlet section 10 and/or outlet pipe section 2 inwalls of valve body 1, again pipeline 9 is inserted in the valve body 1, because of internal diameter relative duct size 9 external diameters of tube sealing device 3 less, so seal arrangement 3 has certain decrement, thereby form sealing; Then the fastening pipe box 8 of wedge shape is enclosed within on the pipeline 9 again, also forms sealing with pipeline 9; At last trim ring is passed pipeline 9, and aims at the locking boss 6 of valve body 1, rotate trim ring again, trim ring because of the gradient on the locking boss 6 to the motion of valve 1 direction, the fastening pipe box 8 stressed inside contractions of wedge shape are firmly embraced pipeline 9, prevent that pipeline 9 from deviating from valve body 1.
