Embodiment
The purpose of this utility model is the defect for overcoming prior art there is provided a kind of safety valve on-line measuring device, under
Face is described in further detail to the utility model in conjunction with the embodiments.
Embodiment 1
As shown in figure 1, a kind of safety valve on-line measuring device, including it is arranged on the pipe nipple 2 of the bottom of safety valve 1 and outside inspection
Survey and connected inside device, the safety valve with pipe nipple, the pipe nipple is perpendicular to safety valve；Under one end and safety valve of the pipe nipple
Portion is connected, and the other end is provided with quick pin end, for being connected with external detection device.
It is worth special, it is emphasized that being additionally provided with stop valve 5 in the middle part of the pipe nipple, is easy to user's Operation switch.
The external detection device is feeder, and the feeder is gas cylinder, and gas cylinder is connected with quick female joint, soon
Fast pin end and quick female joint can be used cooperatively so that pipe nipple can be assembled very easily with feeder.
The operation principle of the present embodiment is：Gas cylinder is connected with pipe nipple by quick pin end and quick female joint.If cutting
Only valve is closed always, then gas cylinder it is always on or close can because a closed gas held space can be formed；
When stop valve is opened, gas is entered inside safety valve by pipe nipple, is now observed on gas cylinder when safety valve valve opening loses heart
Pressure gauge be that can test the set-pressure of safety valve.
Because safety valve is mounted on pipeline, and necessarily exist on pipeline manometric.In the present embodiment, it will pacify
Set-pressure after full valve is connected with gas cylinder by pipe nipple should be that pipeline pressure adds the releasing gas shown on cylinder pressure gauge
The pressure of body.
One of significant design point of the present embodiment is that pipe nipple is provided with safety valve, provided with being easy to safety after this structure
With the connection of other extraneous devices inside valve, the pipe nipple is that processing is welded on safety valve.
The structure of the present embodiment allows to directly reequip safety valve now on the market, reduces cost.
Pipe nipple described in the present embodiment is short duct.
Embodiment 2
The present embodiment and the difference of embodiment 1 are, because the flow media in pipeline is all to need to use in industrial production
Arrive, in order to reduce cost, reduce the discharge of flow media, a kind of safety valve on-line measuring device also includes ball valve, the peace
Full valve is connected on pipeline by ball valve 3 so that when carrying out safety valve testing, directly can be closed ball valve, be carried with gas cylinder
The gas pressure of confession is detected to safety valve.
Embodiment 3
The present embodiment and the difference of embodiment 1 be, further, in order to fast connect, requirement easy for installation, to fast
Fast pin end 4 and the structure of quick female joint 6 are designed.
The quick pin end is cylindrical channel, and described cylindrical channel one end inwall is provided with one at grade
The inwardly projecting neck 7 of circle；The cylindrical channel inwall is provided with inside two grooves 8 being oppositely arranged, the neck and set
There is sealing ring 9.
The quick female joint includes quick female joint main body and elastic component 10, and the quick female joint main body is also inside
Hollow cylindrical configuration, the quick female joint body outer wall is provided with two elastic components being oppositely arranged, described two bullets
Property part between maximum distance be more than the internal diameter of quick pin end, the elastic component is elastic iron plate, described elastic component one end with
Quick female joint main body is fixedly connected, and distance is left between the other end and quick female joint.
The size of the quick female joint causes quick female joint to may be inserted into neck.Between the groove and neck
Distance and the depth of neck should make it that elastic component can be located in groove when neck is inserted in quick female joint, and now
Quickly distance is also left between female joint and neck bottom.
In use, quick female joint is inserted in quick pin end, in quick female joint insertion neck, the sealing in neck
Circle causes quick female joint and quick pin end to be tightly connected, and will not reveal gas；Due between described two elastic components most
It is more than the internal diameter of quick pin end at a distance, therefore when insertion, two elastic components are to draw shape in, when by groove
During part, two elastic component umbrellas are opened and block groove respectively so that quick pin end and quick female joint stable connection, it is difficult to de-
From.And when taking apart, continue up and give quick female joint so that elastic component continues toward extension, when leaving groove part, two
Elastic component is drawn in by the pressure of quick pin end inwall, now, rotates quick female joint, takes out quick female joint, due to turning
When dynamic, elastic component position changes, toward that will not pass through groove part again when rollback, so as to smoothly be taken out.
The quick pin end designed in the present embodiment and quick female joint direct labor clamping, fast and easy are reduced
Workman's workload.
The quick pin end of the present embodiment design and quick female joint dismounting are very convenient, it is not necessary to connected by screw etc.
Part is connected.
According to above-described embodiment, the utility model just can be realized well.What deserves to be explained is, based on said structure design
On the premise of, to solve same technical problem, some made on the utility model are without substantial change or profit
Color, the essence of the technical scheme used is still as the utility model, therefore it should also be as in protection model of the present utility model
In enclosing.
