Abstract
The utility model relates to a high-pressure hard seal ball valve which comprises a middle valve body (1), a lower valve rod (4), a ball body (5), a left valve body and a right valve body (9), a valve seat (11), a spring (12), an upper valve rod (13), a shape seal ring (14), a washer (17) on the middle valve body, a packing (19), a packing gland (20), a spring retaining ring (22) and a wrench (23), and is characterized in that 1-2 impurity collecting grooves (11.1) are formed on the surface of the valve seat (11) which is in close contact with the ball body (5). The high-pressure hard seal ball valve can reduce the abrasion to a spherical valve core and the valve seat, which constituting the sealing surface, and significantly prolong the service life of the whole valve body by accumulating a quantity of very small impurities which are entrained in fluid in the impurity collecting grooves during the process of closing or opening the ball valve.
Description
Technical field
The utility model relates to especially a kind of high pressure hard seal ball valve of a kind of valve.
Background technique
Ball valve is a kind of common valve commonly used, and it mainly is by the turn upper valve rod, makes the spherical spool of being located between the upper and lower valve rod realize the opening and closing of valve pocket along with the rotation of upper valve rod.Owing to be the cutout of realizing ideal by hard sealing relationship between this spherical spool and the valve seat.In using for a long time, if contained fluid is when having the fluid of certain impurity, so very likely along with continual friction between spherical spool and the valve seat, in case especially have on both junction planes after certain impurity, will produce certain abrasive acrion to spool and valve seat.The long term of this phenomenon will make the cut-out sealing effect of hard seal ball valve reduce, and perhaps needs to change.
The model utility content
The purpose of the present utility model: be intended to propose a kind ofly can prolong the hard seal ball valve novel hard seal ball valve in working life.
This high pressure hard seal ball valve, comprise middle valve body, lower valve rod, spheroid, left and right sides valve body 9, valve seat, spring, upper valve rod, shape seal ring, middle valve body upper gasket, filler, Gland, check ring, spanner, it is characterized in that: be provided with the assorted groove of 1 ~ 2 road collection on the surface of the valve seat that closely contacts with spheroid.
This high pressure hard seal ball valve according to above technological scheme proposition, owing on the valve seat of this valve, set up the assorted groove of collection, in the process that ball valve is closed or opened, accumulate in the assorted groove of collection by some fine impurities of will carry secretly in the fluid, minimizing is to the spherical spool that constitutes sealing surface, the wearing and tearing of valve seat, and obviously this is useful for the working life that prolongs whole valve body.

Embodiment
This high pressure hard seal ball valve as shown in the figure, it is a kind of improvement to the congenerous high pressure hard seal ball valve that generally uses at present, it comprises middle valve body 1, lower valve rod 4, spheroid 5, left and right sides valve body 9, valve seat 11, spring 12, upper valve rod 13, shape seal ring 14, middle valve body upper gasket 17, filler 19, Gland 20, check ring 22, spanner 23, it is characterized in that: be provided with the assorted groove 11.1 of 1 ~ 2 road collection on the surface with the spheroid 5 tight valve seats 11 that contact.
This high pressure hard seal ball valve of on valve seat 11, setting up the assorted groove 11.1 of collection, its basic system and to assemble complete and existing high pressure hard seal ball valve the same, owing to be provided with the assorted groove of collection, therefore in the process of valve operation, rotation along with spheroid 5, for the fine impurities that enters between spheroid and the valve seat, will enter in the assorted groove of the collection that is arranged on the valve seat 11.1 along with this rotation.Consequently alleviate the wearing and tearing to valve seat and spheroid during the valve long-play of these impurity, can keep the wind effect, also can effectively prolong the working life of valve simultaneously.In case when valve is maintained, can take out spheroid valve seat is cleaned, just the contaminant removal that accumulates in the assorted groove of collection can be fallen.
Claims (1)
1. high pressure hard seal ball valve, comprise middle valve body (1), lower valve rod (4), spheroid (5), left and right sides valve body (9), valve seat (11), spring (12), upper valve rod (13), shape seal ring (14), middle valve body upper gasket (17), filler (19), Gland (20), check ring (22), spanner (23), it is characterized in that: be provided with the assorted groove (11.1) of 1 ~ 2 road collection on the surface of the valve seat (11) that closely contacts with spheroid (5).
