Abstract
The utility model relates to a transfer and flow valve. This transfer and flow valve includes the valve body, and the both ends of valve body are equipped with import and export respectively, are equipped with one end open -ended inner bag in the valve body, the opening of inner bag is towards the export of valve body, the inside of inner bag is equipped with the regulating piston, and the exit of valve body is equipped with the hole section that is used for with regulating piston sliding fit, be equipped with in the section of hole and realize sealed sealing washer with the cooperation of regulating piston outer peripheral face. The utility model discloses a transfer and flow valve includes the valve body, is equipped with the inner bag in the valve body, and the fluid gets into the valve body from the import, flows past from the passageway between inner bag and the valve body, and flow dimension's change is realized through the adjustment position to the regulating piston, and the sealing washer is established in the hole section that lies in the export, and when having impurity when the regulating piston on, the excircle of regulating piston at first contacts with the hole section and crushes impurity, then the regulating piston just touches the sealing washer, has avoided the sealing washer to be destroyed by impurity.
Description
Technical field
The utility model relates to a kind of flow-adjustable valve.
Background technique
To control the flow velocity of medium and flow in heavy caliber pipe-line system, the facility at protection pipeline and tube outlet place.The Main Function of flow-adjustable valve is exactly in heavy caliber pipeline, is reached the effect of adjust flux and flow velocity in high drop situation by the activity of piston.
Publication number is that the Chinese patent " a kind of plunger type flow-adjustable valve " of CN203374843U discloses a kind of flow-adjustable valve, comprise the valve body for connecting pipeline, valve body internal fixtion has inner bag, the passage passed through for fluid is provided with between valve body and inner bag, one end that inner bag is positioned at valve body import is closed, the other end of inner bag is provided with the throttle orifice passed through for fluid, is provided with regulating piston in inner bag.The working principle of flow-adjustable valve is the area being changed throttle orifice by the position of adjustment regulating piston, thus realizes the adjustment of flow.In order to ensure sealing, be generally arrange seal ring at the external part of regulating piston in prior art, can cause in regulating piston moving process like this, the impurity in fluid is attached on seal ring, and after seal ring contacts with cylinder body, impurity is easy to seal ring to destroy.
Summary of the invention
The purpose of this utility model is to provide a kind of flow-adjustable valve, is located to solve seal ring in prior art the problem that piston causes seal ring easily to destroy.
Flow-adjustable valve of the present utility model is by the following technical solutions: a kind of flow-adjustable valve, comprise valve body, the two ends of valve body are respectively equipped with import and outlet, the inner bag of one end open is provided with in valve body, the opening of described inner bag is towards the outlet of valve body, the inside of described inner bag is provided with regulating piston, and the outlet port of valve body is provided with the hole section for being slidably matched with regulating piston, is provided with the seal ring coordinating with regulating piston outer circumferential face and realize sealing in the section of described hole.
Be provided with sleeve in the section of described hole, described sleeve is provided with seal ring mounting groove, and described seal ring is located in described seal ring mounting groove.
Described sleeve comprises the fixed muffle being welded on hole section one end in valve and the quill be threaded connection at the hole section the other end, and described seal ring mounting groove is surrounded by fixed muffle and quill.
Described seal ring mounting groove is T-slot.
The beneficial effects of the utility model are: flow-adjustable valve of the present utility model comprises valve body, inner bag is provided with in valve body, fluid enters valve body from import, flow through from the passage between inner bag and valve body, regulating piston realizes the change of uninterrupted by adjustment position, and seal ring is located at and is positioned in the hole section of outlet, when regulating piston there being impurity, first the cylindrical of regulating piston contacts with hole section and impurity is crushed, and then regulating piston just touches seal ring, avoids seal ring and is destroyed by impurity.
Accompanying drawing explanation
Fig. 1 is the structural representation in an embodiment of flow-adjustable valve of the present utility model;
Fig. 2 is the enlarged view of the seal ring mounting groove in Fig. 1.
Embodiment
The embodiment of flow-adjustable valve, as Figure 1-Figure 2, flow-adjustable valve comprises valve body 1, the two ends of valve body 1 are respectively equipped with import 4 and outlet 5, the inner bag 2 of one end open is provided with in valve body, the passage passed through for fluid is left between inner bag 2 and valve body 1, the opening of inner bag 2 is towards the outlet 5 of valve body, the inside of inner bag 2 is provided with regulating piston 3, regulating piston 3 can be slidably matched with the inwall of inner bag 2, outlet 5 place of valve body is provided with hole section, seal ring 8 is provided with in the section of hole, seal ring 8 coordinates with the outer circumferential face of regulating piston 3 and realizes sealing, sleeve is provided with in hole section in the present embodiment, sleeve is provided with seal ring mounting groove, seal ring 8 is arranged in seal ring mounting groove, seal ring coordinates with regulating piston outer circumferential face and realizes sealing.
Sleeve in the present embodiment comprises fixed muffle 7 and quill 6, fixed muffle 7 is welded on hole section one end in valve, quill 6 is threaded connection the other end in hole section, fixed muffle 7 welds with hole section, ensure that fluid can not flow out between fixed muffle and the hole section of valve body, seal ring mounting groove in the present embodiment is T-slot, the minor face of T-slot is positioned at the inwall of sleeve, ensure that the reliable fixing of seal ring, can not come off, seal ring mounting groove in the present embodiment is surrounded by fixed muffle and quill, when seal ring changed by needs, being dismantled by quill is fast changeable.
Flow-adjustable valve in the present embodiment in use, regulating piston 3 moves to valve outlet 5 direction, adjustment aisle spare, realize the adjustment of flow, when regulating piston 3 contacts with fixed muffle 7, impurity on regulating piston 3 is grated under the squeezing action of regulating piston 3 cylindrical and fixed muffle 7, and then regulating piston contacts with seal ring 8 and realizes sealing, and avoids the destruction of impurity to seal ring 8.
In other embodiment of flow-adjustable valve, also can be out of shape above-mentioned flow-adjustable valve, in the section of described hole, can not also sleeve be established; Described sleeve can also be integrated type; Described seal ring mounting groove can also be located on quill; Described seal ring mounting groove can also be trapezoidal.
