Abstract
The utility model relates to a faucet, only comprising a shutoff device, with the IPC of F16K5/00, in particular to a self-sealing conical surface gate valve. According to the technical scheme, the self-sealing conical surface gate valve comprises a valve rod (1) with a conical surface gate valve body, a fixing nut (2), a hand wheel (3), a retainer spring (4), a main valve body (5) with a fluid outlet (52), and a valve body connector (6) with a fluid inlet (61); the self-sealing conical surface gate valve is characterized in that the included angle between the valve rod axis (12) of the valve rod (1) with the conical surface gate valve body and a fluid pipeline axis (7) ranges from 30 degrees to 60 degrees, and a main valve body conical surface groove (51) is formed between the main valve body (5) and the conical surface gate valve body (11). The self-sealing conical surface gate valve has the advantages that the self-sealing design is adopted in the conical surface gate valve body and the valve body, so that the sealing performance is good.
Description
technical field
the F16K5/00 that the utility model relates on International Classification of Patents (IPC) only comprises the tap of shut-off means or the classification of cock, especially belongs to a kind of selfsealings conical surface gate valve.
Background technique
tradition gate valve has the little advantage of running resistance, but sealing is poor, has complex structure, and interior space exists dead angle and the large shortcoming of working stroke.
Summary of the invention
the purpose of this utility model is to provide a kind of selfsealings conical surface gate valve, makes gate valve not only have the feature that selfsealings are good, and simple in structure durable in use.
technical solution adopted in the utility model is: it comprises with the valve rod of conical surface gate valve (1), hold-doun nut (2), handwheel (3), holddown spring (4), with the main valve body (5) of fluid output (52), with the valve body interface (6) of fluid inlet (61), it is characterized in that: the valve rod axis (12) of the described valve rod with conical surface gate valve (1) is 30-60 degree with the angle that fluid line axis (7) forms; Between described main valve body (5) and conical surface gate valve (11), be shaped with main valve body conical surface groove (51).
the beneficial effects of the utility model are: 1, because the utility model adopts selfsealings design, good seal performance between conical surface gate valve and valve body; 2, the utility model adopts valve rod and the integrated design of gate valve, solid and reliable; 3, the utility model can utilize the holddown spring that hydrodynamic pressure and valve body apply to compress gate valve outward, reaches forced seal; 4, there is not dead angle in the utility model, can reach optimum food health and prevent that high-pressure liquid is detained dead angle and causes danger.
Brief description of the drawings
accompanying drawing 1 is the utility model schematic diagram.
wherein: 1, with valve rod 11, conical surface gate valve 12, valve rod axis 2, hold-doun nut 3, handwheel 4, holddown spring 5, main valve body 51, main valve body conical surface groove 52, fluid output 53, conical surface gate valve duct 6, valve body interface 61, fluid inlet 7, the fluid line axis of conical surface gate valve.
Embodiment
below in conjunction with accompanying drawing, the utility model is described in further detail.
as shown be the utility model schematic diagram, it comprises with the valve rod of conical surface gate valve (1), hold-doun nut (2), handwheel (3), holddown spring (4), with the main valve body (5) of fluid output (52), with the valve body interface (6) of fluid inlet (61), it is characterized in that: the valve rod axis (12) of the described valve rod with conical surface gate valve (1) is 30-60 degree with the angle that fluid line axis (7) forms; Between described main valve body (5) and conical surface gate valve (11), be shaped with main valve body conical surface groove (51).
the valve rod axis (12) of the valve rod with conical surface gate valve described in the utility model (1) is 45 degree with the angle that fluid line axis (7) forms.
on conical surface gate valve (11) described in the utility model, be shaped with conical surface gate valve duct (53).
during the utility model uses, when the valve rod with conical surface gate valve (1) rotates around valve rod axis (12), conical surface gate valve duct (53) is in the time of fluid line position, pipeline is just unimpeded, in the time that conical surface gate valve duct (53) forwards to beyond fluid line position, conical surface gate valve (11) is just closedown of pipeline.It utilizes hydrodynamic pressure to produce selfsealings to add holddown spring and reach compound forced seal, had fabulous forced seal.The utility model extends flat valve gate valve to make after the conical surface, has not only retained the structure that original gate valve large size does not contact with valve body, and has retained the little advantage of running resistance of gate valve.
Claims (3)
1. a selfsealings conical surface gate valve, it comprises with the valve rod of conical surface gate valve (1), hold-doun nut (2), handwheel (3), holddown spring (4), with the main valve body (5) of fluid output (52), with the valve body interface (6) of fluid inlet (61), it is characterized in that: the valve rod axis (12) of the described valve rod with conical surface gate valve (1) is 30-60 degree with the angle that fluid line axis (7) forms; Between described main valve body (5) and conical surface gate valve (11), be shaped with main valve body conical surface groove (51).
2. selfsealings conical surface gate valve according to claim 1, is characterized in that: the valve rod axis (12) of the described valve rod with conical surface gate valve (1) is 45 degree with the angle that fluid line axis (7) forms.
