Abstract
The utility model relates to a kind of engineering valve, comprise valve body, valve rod and stuffing box gland, described valve inner is provided with switching channels, the lower end of described valve rod is provided with jacking block, described switching channels place is provided with valve plug, and described valve plug upper half part is cone structure, and lower half portion is cylindrical structure, described valve plug lower half portion upper end is provided with seal ring, is provided with supported spring and guide rod between inside described valve plug and valve body.The utility model is by arranging valve plug, seal ring, supported spring and guide rod, this avoid the rigid seal between valve plug and switching channels, valve plug is promoted downwards by the jacking block of valve rod lower end when valve is open simultaneously, when valve shut, valve plug is effective at the pressure acting in conjunction lower seal of hydraulic pressure and supported spring, effectively solve the fluid leakage problem of valve when closed state, practicability is good.
Description
Technical field
The utility model relates to field of mechanical technique, particularly relates to a kind of engineering valve.
Background technique
Equipment, refers to supply people's Long-Time Service aborning, and substantially in Reusability keeps original physical form and the means of production of function and the general name of material goods.The equipment facility equipment aggregate that normally a group is medium-and-large-sized, all cannot take operation and must have fixing pedestal, uses power supply and so on power to operate and impersonal force.
Generally speaking equipment be all placed on exclusive room such as machine room, workshop, factory building, because noise or waste gas can be produced during running, all except invisible information except information equipment is input output, the material that much equipment wants input output tangible, so more need the ability smooth operation of custom-designed place.The kind of equipment and spare part is a lot, for the ease of management and supply, general by following classification.1. part classification is divided; 2. part source divides; 3. part operating characteristic is divided; Standing: refer to often to use, the large and single AUTOMATIC PACKING MACHINE valency of equipment idle cost is lower, the part that needs often to keep certain storage level; 4. spare part precision and manufacture complexity are divided; Key component: refer to the part that precision is high, manufacture difficulty plays a crucial role greatly, in a device.General part: refer to other mechanical spare part except key component.
Valve, as the switch controlling device in the airtight transmitting procedure of flowing medium, uses very extensive in society.Valve of the prior art is long-term opening, in closed using process, and in it, pad or the stuffing box gland inevitably phenomenon such as aging, loosening, finally causes liquid leakage in pipeline.Therefore, for solving the problem, spy provides a kind of new technological scheme.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of engineering valve.
The utility model is achieved through the following technical solutions:
A kind of engineering valve, comprise valve body, valve rod and stuffing box gland, described valve inner is provided with switching channels, the lower end of described valve rod is provided with jacking block, described switching channels place is provided with valve plug, and described valve plug upper half part is cone structure, and lower half portion is cylindrical structure, described valve plug lower half portion upper end is provided with seal ring, is provided with supported spring and guide rod between inside described valve plug and valve body.
As optimal technical scheme of the present utility model, described jacking block is that elastic material is made.
As optimal technical scheme of the present utility model, described valve plug lower half portion diameter is greater than upper half part diameter.
As optimal technical scheme of the present utility model, described seal ring is embedded in lower half portion of valve plug.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, the utility model is by arranging valve plug, seal ring, supported spring and guide rod, this avoid the rigid seal between valve plug and switching channels, valve plug is promoted downwards by the jacking block of valve rod lower end when valve is open simultaneously, when valve shut, valve plug is effective at the pressure acting in conjunction lower seal of hydraulic pressure and supported spring, effectively solve the fluid leakage problem of valve when closed state, practicability is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. valve body; 101. switching channels; 2. valve rod; 3. stuffing box gland; 4. valve plug; 5. seal ring; 6. supported spring; 7. guide rod.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
A kind of engineering valve, comprise valve body 1, valve rod 2 and stuffing box gland 3, described valve body 1 inside is provided with switching channels 101, and the lower end of described valve rod 2 is provided with jacking block 201, and wherein said jacking block 201 is made for elastic material.Described switching channels 101 place is provided with valve plug 4, and described valve plug 4 upper half part is cone structure, and lower half portion is cylindrical structure, and wherein said valve plug 4 lower half portion diameter is greater than upper half part diameter.Described valve plug 4 lower half portion upper end is provided with seal ring 5, and wherein said seal ring 5 is embedded in lower half portion of valve plug 4, and such seal ring 5 can play good seal action.
Be provided with supported spring 6 and guide rod 7 between inside described valve plug 4 and valve body 1, wherein guide rod 7 ensure that the stability in the moving process of valve plug 4.This avoid the rigid seal between valve plug 4 and switching channels 101, valve plug 4 is promoted downwards by the jacking block 201 of valve rod 2 lower end when valve is open simultaneously, when valve shut, valve plug 4 is effective at the pressure acting in conjunction lower seal of hydraulic pressure and supported spring 6, effectively solve the fluid leakage problem of valve when closed state, practicability is good.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
