Abstract
The utility model discloses a multistage depressurization regulating sleeve valve which comprises a valve body (1) and an upper cover (5), wherein the valve body (1) and the upper cover (5) form a valve chamber body. A pressing sleeve (7) and a sleeve group (11) are arranged in the valve chamber body, wherein the pressing sleeve (7) and the sleeve group (11) are matched with each other. Sleeves in the sleeve group (11) are all punched sleeves. The sleeve group (11) sequentially comprises an inner sleeve (8), a middle sleeve (9) and an outer sleeve (10) from inside to outside, wherein hole positions of the inner sleeve (8), the middle sleeve (9) and the outer sleeve (10) are distributed in a staggered mode, a first groove (31) is deeply formed at a hole in the outer wall of the inner sleeve (8), and a second groove (32) is deeply formed at a hole in the outer wall of the middle sleeve (9). The multistage depressurization regulating sleeve valve can achieve a depressurization effect more easily than a single punching type sleeve, manufacturing cost of the valve is greatly reduced due to reduction of the number of the sleeves, and on the same working condition, the number of the sleeves of the multistage depressurization regulating sleeve valve is reduced half the number of sleeves of a common valve.
Description
Technical field
The utility model relates to valve field, especially relates to a kind of multilevel decompression regulating sleeve valve.
Background technique
Sleeve adjusting valve is the device that changes fluid flow in the process control system, is particularly useful for regulating the occasion that unbalanced force is large, the two ends pressure drop is larger.In the high pressure drop situation, generally adopt the form of multilevel decompression, mostly be raising sleeve progression and deal with more and more higher pressure reduction.
Yet because the valve inner volume is limited, generally, increases sleeve quantity the volume of valve is also become greatly thereupon, cause cost of material to rise and processing difficulties.And conventional perforating type sleeve can only realize the one-level pressure drop for valve, very easily produces vibration, also easily produces cavitation phenomenons,
The model utility content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of high-pressure multistage step-down regulating sleeve valve is provided, and realizes reaching in the limited sleeve than the more step-down progression of existing sleeve.
Technical solutions of the utility model are as follows: a kind of multilevel decompression regulating sleeve valve, comprise valve body 1 and loam cake 5, valve body 1 and loam cake 5 form valve chamber, be provided with the gland 7 and the sleeve group 11 that cooperatively interact in the described valve chamber, gland 7 is used for fixed muffle group 11, sleeve in the described sleeve group 11 is the punching sleeve, and described sleeve group 11 comprises inner sleeve 8, middle sleeve 9 and outer sleeve 10 from inside to outside successively, and the Kong Weiwei of described inner sleeve 8, middle sleeve 9 and outer sleeve 10 is in staggered distribution; The outer cinclides place of described inner sleeve 8 is scratched the first groove 31 deeply, and the outer cinclides place of middle sleeve 9 is scratched the second groove 32 deeply, and institute is porose to link to each other at the groove place.
The utility model multilevel decompression regulating sleeve valve, described sleeve group 11 belows are provided with and are provided with spool 3 in valve seat 2, the sleeve group 11, sleeve group 11 tops are provided with valve rod 4, described valve seat 2, spool 3 are connected with valve rod successively and are connected, and band movable valve plug 3 moves up and down during valve rod 4 action.
The utility model multilevel decompression regulating sleeve valve, described valve rod 4 passes loam cake 5, and valve rod 4 is provided with for the stuffing box 6 that seals with the joint of loam cake 5.
The beneficial effects of the utility model are:
The utility model adopts above structure, and fluid is shunted through overcompression, and a series of step-down means such as interflow, expansion more can reach antihypertensive effect than singles' pass sleeve.And the minimizing of sleeve number greatly reduces the manufacture cost of valve, and under the equal working condition, the utility model sleeve quantity reduces half than conventional quantity.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is sectional view of the present utility model;
Fig. 2 is the plane of structure sectional view of the utility model middle sleeve group;
Fig. 3 is the schematic diagram of inner sleeve in the utility model.
Embodiment
Disclosed all features in this specification, or the step in disclosed all methods or the process except mutually exclusive feature and/or step, all can make up by any way.
Disclosed arbitrary feature in this specification (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.
Multilevel decompression regulating sleeve valve as shown in Figure 1, comprise valve body 1 and loam cake 5, valve body 1 and loam cake 5 form valve chamber, be provided with the gland 7 and the sleeve group 11 that cooperatively interact in the described valve chamber, gland 7 is used for fixed muffle group 11, described sleeve group 11 belows are provided with and are provided with spool 3 in valve seat 2, the sleeve group 11, sleeve group 11 tops are provided with valve rod 4, and described valve seat 2, spool 3 are connected with valve rod successively and are connected, and band movable valve plug 3 moves up and down during valve rod 4 action.Described valve rod 4 passes loam cake 5, and valve rod 4 is provided with for the stuffing box 6 that seals with the joint of loam cake 5.
Sleeve group as shown in Figures 2 and 3, the sleeve in the sleeve group 11 is the punching sleeve, and described sleeve group 11 comprises inner sleeve 8, middle sleeve 9 and outer sleeve 10 from inside to outside successively, and the Kong Weiwei of described inner sleeve 8, middle sleeve 9 and outer sleeve 10 is in staggered distribution; The outer cinclides place of described inner sleeve 8 is scratched the first groove 31 deeply, and the outer cinclides place of middle sleeve 9 is scratched the second groove 32 deeply, and institute is porose to link to each other at the groove place.
During work, after fluid is introduced into outer sleeve 10, arrive the second groove 32 places, fluid begins shunting by the place, hole of middle sleeve 9, then locate through the hole of the first groove 31 and inner sleeve 8, fluid collaborates with the fluid that other runners are come again, and therefore with respect to the punching sleeve, every grade of sleeve can provide the two-stage step-down more.
The utility model adopts above structure, and fluid is shunted through overcompression, and a series of step-down means such as interflow, expansion more can reach antihypertensive effect than singles' pass sleeve.And the minimizing of sleeve number greatly reduces the manufacture cost of valve, and under the equal working condition, the utility model sleeve quantity reduces half than conventional quantity.
The utility model is not limited to aforesaid embodiment.The utility model expands to any new feature or any new combination that discloses in this manual, and the arbitrary new method that discloses or step or any new combination of process.
