Abstract
The utility model discloses a kind of self-bleeding ball valve that has, there is valve body, valve ball, described valve ball is built in valve body, also comprise valve rod, described valve rod lower end is vertically connected with valve ball through being positioned at valve body upper shed place, and described valve rod upper end is through through hole and the fastening nuts of handle, described valve ball external peripheral surface is provided with exhaust port, bottom brand-new design increases exhaust port, and spheroid, by improving, increases automatic ventilating function.When ball valve is closed, the gas of outlet end or liquid can be discharged by improved spheroid and valve body exhaust port.Make the noresidue in pipeline of gas and liquid.By valve body bottom, from threaded exhaust port, client can be according to self-demand pipe laying, make more than gas or the liquid place that is discharged to client's appointment.And when client does not need certainly to let out function, the exhaust port of bottom can be blocked.
Description
Technical field
The utility model relates to industrial valve field, especially relates to a kind of self-bleeding ball valve that has.
Background technique
Existing two-piece type straight-through type ball valve on market, its valve body is brass, and handle is cast iron quality, and spheroid is brass.Ball valve two ends are for being threaded, the non air exit hole of valve body own.Ball valve is when closing, and due to its sealing, residual gas or liquid cannot be discharged.If residual gas or liquid change, make its pipeline pressure excessive, can cause the accidents such as ball valve damage, Pipeline damage.
Model utility content
The purpose of this utility model is the problem that solves above-mentioned proposition, and a kind of simple in structure, band automatic ventilating function is provided, and alleviates pipeline pressure, and what extend the ball valve life-span a kind ofly has a self-bleeding ball valve.
The purpose of this utility model realizes as follows: a kind of have a self-bleeding ball valve, there is valve body, valve ball, described valve ball is built in valve body, also comprise valve rod, described valve rod lower end is vertically connected with valve ball through being positioned at valve body upper shed place, described valve rod upper end is through through hole and the fastening nuts of handle, and described valve ball external peripheral surface is provided with exhaust port.
Further optimized project is, above-mentioned a kind of self-bleeding ball valve that has, and described exhaust port is through hole.
Further optimized project is, above-mentioned a kind ofly have the upper end of valve rod described in self-bleeding ball valve and through bedding and padding center hole, be connected with handle with pressure cap successively.
Further optimized project is, above-mentioned a kind of self-bleeding ball valve that has, is positioned at the described valve ball of valve body two ends and is provided with valve seat, and described valve seat and valve gap are tightly connected.
Advantage of the present utility model: 1, the utility model provides a kind of ball valve with automatic ventilating function.This ball valve, valve body is originally as brass, and bottom brand-new design increases exhaust port, and spheroid, by improving, increases automatic ventilating function.When ball valve is closed, the gas of outlet end or liquid can be discharged by improved spheroid and valve body exhaust port.Make the noresidue in pipeline of gas and liquid.By valve body bottom, from threaded exhaust port, client can be according to self-demand pipe laying, make more than gas or the liquid place that is discharged to client's appointment.And when client does not need certainly to let out function, the exhaust port of bottom can be blocked.
2, secondly nickel plating or chromium plating processing can be carried out in ball valve body surface, prevent that brass is long-time exposed in air, and oxidation stain occurs, and make ball valve more durable.At handle end cover, there is Antislip plastic cover, be easier to operation.On handle, increased active block stop and can lockhole.In the time of can making ball valve open or close according to the wish of oneself, ball valve handle be pinned, other people just cannot close or open ball valve.
Accompanying drawing explanation
For content of the present utility model is more easily expressly understood, according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein below
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the blast structural representation of Fig. 1.
Embodiment:
See shown in Fig. 1 and Fig. 2, a kind of have a self-bleeding ball valve, there is valve body 2, valve ball 3, described valve ball 3 is built in valve body 2, also comprise valve rod 7, described valve rod 7 lower ends are vertically connected with valve ball 3 through being positioned at valve body 2 upper sheds place, and described valve rod 7 upper ends are fastening through through hole and the nut 6 of handle 8, and described valve ball 3 external peripheral surfaces are provided with exhaust port 10.Described exhaust port 10 is through hole.The upper end of described valve rod 7 is connected with handle 8 with pressure cap 6 through bedding and padding 5 center holes successively.Be positioned at the described valve ball of valve body 23 two ends and be provided with valve seat 4, described valve seat 4 is tightly connected with valve gap 1.
Its working procedure is: as can be seen from the figure the ball valve with automatic ventilating function comprises valve gap 1, valve body 2, valve seat 4, valve ball 3 and ball valve opening/closing mechanism.The integral body that described valve body 2 is formed in one, it comprises block, screw thread exhaust port, entrance point is inipple.Described valve gap 1 has interior plug portion and stop portions, wherein said valve seat 4 is 2, described valve ball 3 is arranged in described valve body 2 by two valve seats 4 of both sides, one side valve seat and described stop portions are used for stopping that opposite side valve seat skids off from outlet end, and described stop portions has outside thread or internal thread, can with other equipment connections.
Described ball valve opening/closing mechanism comprises handle 8, pressure cap 6, bedding and padding 5, valve rod 7, stainless steel nut 9, and described handle 8 is arranged on the block at valve body 2 tops, and described valve rod 7 is worn successively stainless steel nut 9, handle 8, pressure cap 6, bedding and padding 5 and is inserted in valve ball 3.When ball valve is closed, the gas of outlet end or liquid flow to exhaust port by valve ball side opening and discharge.
Nickel plating can be carried out in ball valve body surface in addition or chromium plating is processed, and prevents that brass is long-time exposed in air, and oxidation stain occurs, and makes ball valve more durable.At handle end cover, there is Antislip plastic cover, be easier to operation.On handle, increased active block stop and can lockhole.In the time of can making ball valve open or close according to the wish of oneself, ball valve handle be pinned, other people just cannot close or open ball valve.
Above-described specific embodiment; the purpose of this utility model, technological scheme and beneficial effect are further described; institute is understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
