Abstract
The utility model discloses a positioning connector of a bottle head valve. The positioning connector comprises a connector body and a three-way connector (4). The connector body is a positioning bolt (8), one end of the positioning bolt (8) is connected to a gas outlet (2) of a valve body (1), one end of the three-way connector (4) is connected with the positioning bolt (8) in a sleeved mode, bonded washers (3) are arranged between the three-way connector (4) and the valve body (1) and between the three-way connector (4) and the big end of the positioning bolt (8) respectively, the other end of the three-way connector (4) is connected with a threaded sleeve (9) and a pressing screw cap (10), and a gas channel enabling the gas outlet (2) to be communicated with the three-way connector (4) is arranged in the positioning bolt (8). By the adoption of the structure, because the three-way connector can rotate in random directions with the positioning bolt as a fulcrum shaft, what is only needed is to rotate the three-way connector regardless of the requirements for directions of the gas outlet in actual use, positioning is achieved, and the positioning connector is very easy and convenient to operate.
Description
Technical field
The utility model relates to the technical field of valve, is specifically a kind of landing nipple for the bottle valve in the propellant bottle group in fire-fighting system.
Background technique
At present; in fire-fighting system so that gas cylinder be generally large-scale steel cylinder; the bottle valve being equipped with on steel cylinder; for controlling the gas communication in steel cylinder; and the valve body air outlet place of bottle valve can be connected with joint conventionally, as shown in Figure 1, jiont treatment is in a side of valve body 01; joint shown in accompanying drawing is angle coupling, is for the gas from the air outlet 02 of valve body 01 is ejected with other direction.This angle coupling of prior art comprises joint body 04, bonded washer 03, swivel nut 05 and clamping nut 06; The threaded one end of joint body 04 is connected to 02 place, air outlet of valve body 01 and passes through bonded washer 03 and valve body 01 end face press seal, in joint body 04, have the mutually perpendicular gas channel of formation, the other end of joint body 04 is connected with swivel nut 05 and the clamping nut 06 for connecting other pipe joints.
But there is following shortcoming in the joint of the bottle valve of above-mentioned this structure:
1) owing to being any direction from the direction of valve body air outlet gas out, and actual with time direction be the trend that need to change by angle coupling its gas, but, when gas direction in the time changing actual use, need again Screw joint or unscrew joint in the other direction, therefore, in the time of Screw joint, can damage each component of this joint, in the time unscrewing joint, can easily cause the Leakage Gas of this joint;
2) simultaneously, in order to change in use outgassing direction, and to reach the component that neither damage joint and can not cause again the Leakage Gas of joint, can only be by pulling down joint, the length of connecting thread or the thickness of adjustment seal ring that change joint body are realized, therefore, this is concerning forming the product of producing in batches, be both time-consuming, easily get again auxiliary component wrong, greatly affect manufacturing efficiency.
Model utility content
Technical problem to be solved in the utility model is that a kind of landing nipple of the bottle valve that the air outlet direction of bottle valve can be realized to any direction adjusting is provided.
For solving the problems of the technologies described above, the landing nipple of the bottle valve that the utility model provides, comprises the joint body being connected with valve body, the swivel nut and the clamping nut that are connected with other pipe joints; It also comprises tee union, joint body is holding down bolt, one end of described holding down bolt is connected to the air outlet place of valve body, one end of tee union is socketed on holding down bolt, and between tee union and valve body and between tee union and the major part of holding down bolt, be equipped with bonded washer, the other end of tee union is connected with swivel nut and clamping nut; In holding down bolt, there is the gas channel that is communicated with air outlet and tee union outlet passageway.
Gas channel in described holding down bolt comprises radially pore of axial pore and at least one, and there is annular groove on the outer circle wall of holding down bolt, radially one end of pore is communicated with axial pore, and the other end is connected with annular groove, and annular groove is communicated with the outlet passageway of tee union.
Described radially pore is four, along the circumferential direction uniform.
Adopt after above structure, the utility model compared with prior art, has the following advantages:
1), due to being rotationally connected between tee union and holding down bolt, in other words, tee union can rotate take holding down bolt as fulcrum any direction, therefore, in the time that reality is used, no matter the how requirement of the direction of air outlet only need to be rotated tee union and just can be realized, operate very simple and convenient; , in one end both ends of the surface that tee union is connected with holding down bolt, all seal by bonded washer meanwhile, more guaranteed that gas can not leak from joint;
2) simultaneously, if when this joint finds that there is Leakage Gas in use, without the length of connecting thread or the thickness of adjustment seal ring that change in addition joint body, only need screwed in place bolt again, be applicable to the product of batch production, without independent preparation, greatly enhance productivity.
