Description

Non-leakage flat gate valve
Technical field
The utility model relates to a kind of sealing configuration of gate valve, and particularly a kind of valve plate is provided with the plate valve of automatic compensation sealing structure.
Background technique
Gate valve is one of valve commonly used in the pipework.Plate valve is a kind of in the gate valve, and to be the uniform thickness valve plate match with the end face of two valve seats in the valve body its structure characteristic, and the cooperation position of radial regulation valve plate and valve wall gets final product the flow through discharge value of valve seat of regulator solution body medium.Though plate valve and similar valve structure compared compactness, pressure-bearing height, its body cavity space is little, and directly processing valve seat difficulty is big on the valve body body, measures inconvenience, is difficult to guarantee the valve seat machining accuracy.The accuracy of manufacturing of valve seat directly influences the sealability that valve plate matches with valve seat.Control system working pressure in the device such as oil drilling, oil recovery is very high, and also very high to supporting plate valve sealability requirement, the plate valve of prior art can not satisfy supporting requirement.
The model utility content
The utility model is primarily aimed at big, the measurement inconvenience of the valve seat difficulty of processing with body structure in the prior art valve body, the shortcoming of valve seat and valve plate fitted seal difference, a kind of valve seat that the branch body structure is set in valve body is proposed, the axially displaceable non-leakage flat gate valve of valve seat, this valve arrangement is simple, easy to manufacture, clearance automatic compensation, sealing are reliable.
The utility model is achieved through the following technical solutions technical goal.
Non-leakage flat gate valve, it comprises valve seat, setting sleeve, core retainer plate, valve plate, valve body, seal ring and gate valve controlling mechanism.Described valve plate is the uniform thickness rectangular slab, and its upper end is connected with the screw rod of gate valve controlling mechanism, and the middle part is entity or has dark bar lifting screw thread, and the bottom is provided with and the measure-alike through hole of valve seat endoporus, and valve plate cooperates with the valve seat end face seal of the left and right sides.Its improvements are: described setting sleeve is a cylindrical shape, is located at respectively on the relative valve interior wall of valve plate both ends of the surface, and setting sleeve one end and valve interior wall are located by connecting.Described valve seat is the ring that is provided with outer step, and valve seat is with step major diameter Spielpassung in big outer diameter section wall and the setting sleeve, with the coaxial core retainer plate of valve seat also in the lump with setting sleeve endoporus Spielpassung, valve seat engages with core retainer plate and is provided with seal ring between the end face.Also be provided with seal ring between described core retainer plate and the valve body jointing end face.
Seal ring in the said structure is to make whole rubber-like member with rubber material, and its cross section is circle or rectangle.Utilize the rebound elasticity behind the seal ring pressurized, valve seat and valve plate end face are fitted and increase sealability.
The utility model compared with prior art has following good effect:
1, adopt the split structural design, valve inner is simple in structure, and the body cavity space is big relatively, is convenient to machining, is convenient to detect;
2, utilize rebound elasticity behind the seal ring pressurized, promote valve seat and the applying of valve plate end face, directly improve sealing effect;
3, split constitutional detail, accuracy of manufacturing height, product percent of pass height;
4, split constitutional detail easy access, renewal part is convenient, and user cost is low.
Description of drawings
Fig. 1 is the utility model structural profile schematic representation.
Fig. 2 is the valve plate both ends of the surface and the schematic representation that cooperates of built-in valve seat, core retainer plate and the seal ring of setting sleeve.
Embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is further described.
Non-leakage flat gate valve shown in Figure 1, it comprises valve seat 1, setting sleeve 2, core retainer plate 3, valve plate 4, valve body 5, seal ring 6 and gate valve controlling mechanism 7.Described valve plate 4 is the uniform thickness rectangular slab, and its upper end is connected with the screw rod of gate valve controlling mechanism, and the middle part is entity or has dark bar lifting screw thread, and the bottom is provided with and the measure-alike through hole of valve seat 1 endoporus, and valve plate 4 cooperates with valve seat 1 end face seal of the left and right sides.Valve seat 1 is installed in valve body 5 inner chambers by setting sleeve 2, and core retainer plate 3 and valve seat 1 coaxial and core retainer plate 3 and setting sleeve 1 Spielpassung are provided with seal ring 6 between valve seat 1 and core retainer plate 3 mating faces, are provided with seal ring 6 too between core retainer plate 3 and the valve body 5 inwall mating faces.Valve plate 4 middle parts are entity structure in the present embodiment, and the material of seal ring 6 is butadiene rubbers, and the cross section of seal ring 6 is circular.Seal ring 6 is in pressured state when mounted, utilizes the rebound elasticity behind seal ring 6 pressurizeds, promotes valve seat 1 and fits with valve plate 4 end faces, effectively improves the sealing effect that cooperatively interacts.Setting sleeve 2 in the utility model, valve seat 1, core retainer plate 3 and seal ring 6 are the split constitutional detail, and valve body 5 internal structures are simple, the space is big, are convenient to machining, are convenient to detect the accuracy of manufacturing height.Renewal part is convenient during the product maintenance, and user cost is low.
