Abstract
The utility model provides overall suspended pellet sampling thief load resistance regulating device, it is characterized in that: comprise upper body, middle body, lower body; Described middle body embeds in the cavity that upper body and lower body form, and the resistance adjuster bar outside upper body is stretched out in middle body connection one, and middle body can be rotated by adjuster bar drive in the cavity of upper body and lower body; Upper body is corresponding with middle body arranges air vent.This apparatus structure is reliable, and be easy to operation, and can reuse continuously, continue to pay dues use without male offspring, without the need to repeatedly dismantling in resistance adjustment process, effectively can save man-hour, raising the efficiency.
Description
Technical field
The utility model relates to particle sampler field, specifically, relates to a kind of overall suspended pellet sampling thief load resistance regulating device.
Background technology
According to overall suspended pellet sampling thief vertification regulation (JJG 943-2011) requirement, need do the calibrating of load capacity to overall suspended pellet sampling thief, verification process need increase the load of 4kPa ~ 6kPa gradually at the thief hatch of tested sampling thief.Generally adopt in existing most unit assay process and in original verifying attachment, add one or more filter membrane to realize the increase of load.
There is following defect in the method:
1. the load resistance that different filter membrane produces varies in size, and selects inconvenience;
2. the load resistance of same filter membrane generation is certain, can not arbitrarily regulate;
3. add, need calibrating installation be dismantled when subtracting filter membrane, waste time and energy, affect work efficiency;
4. to reuse number of times not high for filter membrane, and waste is serious.
Utility model content
In order to solve ubiquitous defect in traditional overall suspended pellet sampling thief load capacity checkout procedure, the utility model provides a kind of overall suspended pellet sampling thief load resistance regulating device.
Its technical scheme is: overall suspended pellet sampling thief load resistance regulating device, comprises upper body, middle body, lower body; Described middle body embeds in the cavity that upper body and lower body form, and the resistance adjuster bar outside upper body is stretched out in middle body connection one, and middle body can be rotated by adjuster bar drive in the cavity of upper body and lower body; Upper body is corresponding with middle body arranges air vent.
Further, described air vent quantity is 3-8.
As preferably, described air vent is circular or fan-shaped.
As preferably, described middle body and upper body, middle body and lower body are all sealed by outside framework oil seal device.
As preferably, be bolted to connection between described upper body and lower body, locate, ensure that the gap length between upper body and lower body is suitable, middle body smooth rotation and air tight.
Overall suspended pellet sampling thief load resistance regulating device provided by the utility model, has the following advantages:
First: this apparatus structure is reliable, be easy to operation;
Second: without the need to repeatedly dismantling in resistance adjustment process, effectively can save man-hour;
3rd: load resistance can regulate gradually, has controllability;
4th: can unlimitedly reuse, continue to pay dues use without male offspring, cost-saving.

[critical piece symbol description]
1: dragulator upper body; 2: body in dragulator; 3: dragulator lower body; 4: resistance adjuster bar; 5: outside framework oil seal.
Embodiment
Below in conjunction with accompanying drawing and embodiment of the present utility model, the utility model overall suspended pellet sampling thief load resistance regulating device is described in further detail.
As can be seen from Fig. 1 and Fig. 2, overall suspended pellet sampling thief load resistance regulating device, comprises body 2 in dragulator upper body 1, dragulator, dragulator lower body 3, resistance adjuster bar 4 and outside framework oil seal 5.Outside framework oil seal 5 clamps respectively and is fastened on inside dragulator upper body 1 and dragulator lower body 3; In dragulator, body 2 embeds in outside framework oil seal 5 endoporus; Resistance adjuster bar 4 to be fastened in dragulator on body 2; Dragulator upper body 1 and dragulator lower body 3 are connected with bolt and locate, and regulate gap length to middle body smooth rotation and air tight.By rotary resistance adjuster bar 4, body 2 in dragulator is rotated in dragulator upper body 1, its ventilating opening and dragulator upper body 1 ventilating opening produce staggered, to change the ventilation of overall air vent, thus air-flow by time produce the resistance of different size.Described air vent quantity, shape can be arranged as required, and preferred version is 3-8, and air vent is circular or fan-shaped, and large I needs setting according to detection.Overall suspended pellet sampling thief load resistance regulating device of the present utility model can adopt polytetrafluoroethylmaterial material, substantially noiseless to sample.
The use procedure of overall suspended pellet sampling thief load resistance regulating device of the present utility model is as follows: during use, dragulator upper body 1 is connected with orifice metre, dragulator lower body 3 is connected with orifice metre hypocentrum, resistance adjuster bar 44 is adjusted to zero-bit (i.e. light condition), after overall suspended pellet sampling thief is stable, the flow error of indication under light condition can be examined and determine; After completing, without the need to dismounting, directly regulate the resistance adjuster bar 44 of this device, make load resistance slowly be increased to (i.e. load condition) between 4kPa ~ 6kPa, after overall suspended pellet sampling thief is stable, the flow error of indication under load condition can be examined and determine.Whole process, once connects, and can realize calibrating that is unloaded and load two states, effectively can save man-hour, increase work efficiency, cost-saving.
