Background technology

Valve is a kind of industrial important fluid control devices, is related to national economy many departments, is national economy The fundamental equipments of development, it is applied to have in fluid delivery system cut-off, regulation, water conservancy diversion, prevents adverse current, voltage stabilizing, divides The function such as stream and overflow pressure relief, conduit fluid pressure is required in fields such as chemical industry, oil, pharmacy, metallurgy in the course of the work Stabilization, prevents pressure inequality from causing peril, particularly when inspection by sampling and blowdown is needed, should ensure to get appropriate Sample and timely blowdown, will also be prevented from being overflowed from the first valve body because adjusting improper product, and single valve is only leaned on during this Door regulating part is to be difficult quickly, accurately to realize, valve group can gather the regulatory function of various valves, fast and effectively regulation pressure Power simultaneously keeps stable pressure.

Two traditional valve groups are by main valve body, the first control valve and the second control valve group into first controls valve and the second control Valve is installed on cut-out or the UNICOM of each runner of main valve body and control bound body, the first traditional control valve include the first valve body and First valve rod, the first valve body and main valve body UNICOM are set, and the first valve rod is displaced into the first valve body, and the first valve rod is towards main valve body End be provided with the first closing element, first closing element by the first valve rod control constitute cutting for runner closer or far from main valve body Disconnected or UNICOM,

The first traditional closing element is the sealing block of quality of rubber materials, and the sealing block can be gradually under the washing away of long-time medium Deformation, causes the first closing element thoroughly to cut off corresponding runner, causes medium to reveal.

The content of the invention

In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of good airproof performance, service life Two valve groups long.

To achieve the above object, the utility model provides following technical scheme：Including main valve body, the first control valve and the Two control valve groups are into described the first control valve and the second control valve is installed on cutting for each runner of main valve body and control bound body Disconnected or UNICOM, the first described control valve includes the first valve body and the first valve rod, and the first described valve body sets with main valve body UNICOM Put, the first described valve rod is displaced into the first valve body, it is close that the first described valve rod is provided with first towards the end of main valve body Closing member, the first described closing element is made up of cut-out or the UNICOM of runner the control of the first valve rod closer or far from main valve body, and it is special Levy and be：The first described closing element includes the main body being adapted with flow channel shape, and the main body is towards fluid inflow direction and flows Road is coaxially arranged with conical cavity, and the diameter of the conical cavity is gradually reduced along fluid flow direction.

By using above-mentioned technical proposal, the fluid into conical cavity can be by the first closing element of conical cavity periphery to runner Wall is extruded, so that strengthen the sealing property of the first closing element and runner, and hydraulic pressure is bigger, and sealing property is gradually strengthened.

The utility model is further arranged to：The rigid backbone that section takes the shape of the letter U is provided with the first described closing element, should The U-shaped opening of rigid backbone is set towards conical cavity.

By using above-mentioned technical proposal, U-shaped skeleton is set according to the first closing element, and the first closing element of enhancing is shock proof Ability, it is to avoid the deformation under lasting thump, increases the service life.

The utility model is further arranged to：The first described valve rod is provided with the installation extended in the first closing element Post, described rigid backbone is correspondingly arranged on the mounting hole of screw thread cooperation with mounting post.

By using above-mentioned technical proposal, mounting post coordinates with mounting hole makes the first closing element be mounted at first Valve rod, being capable of fast assembling-disassembling, two valve group whole service lifes of extension after the first closing element long-time use.

The utility model is further arranged to：The movement for the movement of the first closing element is provided with the first described valve body Chamber, the first described valve rod is located at mobile cavity inner sleeve and is provided with sealing ring, and described sealing ring periphery is close with mobile cavity inner circumferential activity Envelope coordinates, and the first described valve rod is located in mobile cavity to be also arranged with will seal the back-moving spring that the closing element of ring first resets.

By using above-mentioned technical proposal, mobile cavity is used to be moved back and forth for the first closing element, sets up sealing ring and ensures to move Dynamic sealing between chamber and runner, it is to avoid fluid is leaked out to outside the first valve body from mobile cavity.

The utility model is further arranged to：Described sealing ring outer peripheral face has been placed equidistant annular and has temporarily put groove vertically, The annular temporarily puts triangle of the groove in the mobile cavity wall of opening direction.

By using above-mentioned technical proposal, due to the characteristic of fluid, the fluid for climbing shifting along mobile cavity cavity wall can put groove temporarily Shifting is climbed in interior aggregation, stopping, until this temporarily puts groove full of fluid, so that increase the sealing between mobile cavity and runner, and further Avoid fluid leakage.

The utility model is further described with reference to the accompanying drawings and detailed description.

Brief description of the drawings
