Abstract
The utility model belongs to the technical field of a fluid valve. The utility model mainly comprises a valve seat, a valve body, a valve core rod and a handwheel, wherein, a position at the lower part of the valve core rod is provided with a liquid leading-out groove, the corresponding position of the valve body and the liquid leading-out groove of the valve core rod is connected with a medium conduit, and the liquid leading-out groove is communicated with the medium conduit. The handwheel is rotated to cause the valve core rod to extend into the liquid, and the liquid enters the medium conduit for sampling through the liquid leading-out groove. The structure of the utility model avoids the traditional sampling that a sampling tube and a trip valve are connected with a main tube, and a sampling valve has complex structure and complicated operation, and meanwhile, resource waste and environment pollution are reduced.
Description
The utility model belongs to the fluid valve technical field, mainly proposes a kind of environment protection type sampling valve, is mainly used in the sampling of petrochemical industry liquid pipeline.
Present petrochemical industry or other chemical industry, when being sampled, takes in liquid on pipeline, to connect the mode of two valve body gate valves and stop valve, need open stop valve during sampling, bleed off the raffinate of internal memory, after open gate valve, regulate stop valve, take the matter sample in the liquid pipeline, even so, but the dead point is arranged all between from the pipeline to the valve body, remain with liquid (going up first phase) raffinate, the levels of precision of influence sampling, the raffinate serious environment pollution of releasing.There is the comparatively complicated defective of installation, operation in this kind structure simultaneously.
The purpose of this utility model promptly is the environment protection type sampling valve that proposes a kind of new structure, makes its characteristics with Direct Sampling, thereby solves the shortcoming that existing sampling valve structure exists.
The utility model takes following technological means to finish its invention task: it includes valve seat, valve body, valve core bar and the handwheel that is communicated with the liquid pipeline, valve body is threaded with valve seat and adds Sealing and forms integrative-structure, drive the valve core bar bottom that moves up and down by handwheel and set liquid derivation groove, be connected with media lines at valve body and the corresponding position of valve core bar liquid derivation groove, and liquid derivation groove is communicated with media lines.
Rotate handwheel, the valve core bar stretches in the liquid, and liquid is derived groove by the liquid of valve core bar and entered media lines, and the valve core bar upwards resets, and its valve core bar lower end is that cylindrical body sealing liquid enters, and sampling finishes.
The utility model is combined as a whole fluid line and sampling valve, avoided traditional sampling by female pipe pick out sampling pipe, that sampling pipe adds cut-off valve, sampling valve is both loaded down with trivial details, complicated, investment must be put again greatly and be the accounts show a surplus of liquid and just can adopt the uncivil production that new sample had not only been wasted resource but also befouling environment, its structural design is simple, and the operation sampling is quite convenient.
Embodiment:
Accompanying drawing 1 is the utility model structural representation.
As shown in drawings: the utility model valve seat 8 can spiral marking connection liquid pipeline, when big caliber, valve seat 8 can be designed to a circular band arc seat and be welded in combination on the female pipe of liquid pipeline, valve body 7 is with valve seat 8 scyewed joint and add Sealing formation integrative-structure, valve core bar 3 is encrypted packing material 6 with valve base chamber and is tightened up with Gland 5, guarantee the better seal performance, valve core bar 3 lower positions have set liquid and have derived groove 10, so that the valve core bar when being displaced downwardly to certain position liquid can derive the groove conducting with liquid, derive groove 10 corresponding positions at valve body 7 and liquid and be connected with media lines 9, and make liquid derive groove and media lines 9 UNICOMs, between valve body 7 tops and valve core bar 3, there is stuffing box packing 6 also to tighten up with Gland 5, be similarly the assurance excellent sealing performance, valve body 7 upper end portion scyewed joint valve gaps 4, be provided with the handwheel 1 that connects with valve core bar 3, and tighten up with tightening nut 2 and to be one.
Claims (1)
