Abstract
A sampling valve combines a valve and a sampler, comprising a valve composed of a valve body, a rotary handle, a lead screw, a sealing flap and a sealing base and a sampler composed of a sampling valve body, a sampling core, a O-shaped ring and a protective cover, wherein a connecting chain is provided between the protective cover and the valve body, a sealing flap protective sleeve is provided between the lead screw and the sealing flap, the sealing flap protective sleeve is sheathed at the lower end of the lead screw and is rotary, the sealing flap is provided in the sealing flap protective sleeve, the sealing base is provided with an annular protrusion which can be embedded into the sealing flap when in seal. The sampling valve combines the valve and the sampler, to reduce production cost and maintenance cost, and realize simple and accurate installment, maintenance and check, and the utility model adopts the sliding between the sealing flap protective sleeve and the lead screw to replace the friction sliding between the sealing flap and the sealing base, to reduce the abrasion on the sealing flap and prolong the service life of the valve. The corresponding annular protrusion and the sealing flap have soft seal thereof to improve the sealing degree of the valve.
Description
Technical field
The utility model relates to a kind of electric power and the extraordinary valve of medication chemistry, particularly a kind of sampling cock.
Background technique
Sampling is the technology that electric power is used always with the medication chemistry industry, in process of production, usually needing sampling in time to chemically examine, and the past all is to be provided with special sample tap on pipeline generally, opens the sample tap sampling during sampling.Use for carrying out various checks,, guarantee high-quality production so that grasp the parameter of liquid whenever and wherever possible.
This is a more complicated installing of pipeline, and sample tap also needs to install independent valve.
The model utility content
For remedying above-mentioned deficiency, the utility model provide that a kind of valve and sample collector unite two into one sampling cock.
The utility model sampling cock; comprise valve body, rotatory handling, screw mandrel, sealing lobe and sealing seat, wherein: described valve body is provided with the sampling valve body with the valve body one, wherein is provided with the sampling core; O type circle and safety cover have a connection chain between described safety cover and the valve body.
The utility model sampling cock, wherein: be provided with a sealing lobe sheath between described screw mandrel and sealing lobe, described sealing lobe sheath is to be enclosed within described screw mandrel lower end, can rotate, and described sealing lobe is contained in the described sealing lobe sheath.
The utility model sampling cock, wherein: described sealing seat is provided with an annular protrusion, and this projection can be absorbed in the sealing lobe during sealing.
The utility model sampling cock unites two into one valve and sampler, has reduced cost of production and maintenance cost, and makes installation, safeguards and detects more convenient, more accurate; With the slip between sealing lobe sheath and the screw mandrel replaced between sealing lobe and the sealing seat slip, thereby the fretting wear that has alleviated the sealing lobe has prolonged working life of valve; Soft sealing structure, design has an annular protrusion on the metallic seal seat, in the sealing lobe that this metal bump can be softer up to one's neck in sealing, change traditional two structures that sealing surface all is the plane up and down with this, increased sealing area, thereby increase substantially sealing effect, fundamentally solved the problem that conventional valves is leaked easily.
Description of drawings
Fig. 1 is the side view of the utility model sampling cock;
Fig. 2 is the front view of the utility model sampling cock.
Embodiment
For further setting forth the utility model sampling cock, do more detailed explanation below in conjunction with embodiment.
Fig. 1 is the side cutaway view of the utility model sampling cock, and Fig. 2 is the front view of the utility model sampling cock.
As we can see from the figure; the utility model sampling cock is made up of valve body 1, rotatory handling 10, screw mandrel 2, sealing lobe 3, sealing seat 5 and sampler 8; valve and sample collector unite two into one; sampler is by sampling valve body 11; sampling core 8; O type circle 13 and safety cover 12 are formed, and a connection chain 9 is arranged between safety cover 12 and the valve body 1.The liquid that flows through in the valve directly arrives sampling core 8, opens safety cover 12, connects sampling core 8 with outside flexible pipe, just can direct sample send to chemical examination.
So only need a sampling cock just substitute a valve and two devices of a sampler in the past, saved a device, just reduced cost of production and maintenance cost, and made installation, safeguard and detect more convenient, more accurate.As the part of machinery equipment, owing to lacked a device, reduced frequent Installation And Test, it is just more stable to work together, and makes the operation of complete equipment also safer.
Be provided with a sealing lobe sheath 4 between screw mandrel 2 and sealing lobe 3, sealing lobe sheath 4 usefulness metals are made, and are enclosed within screw mandrel (2) lower end, can rotate, and the sealing lobe is contained in the sealing lobe sheath 4, and its lower plane will be lower than the bottom of sealing lobe sheath.Sealing lobe sheath is to be enclosed within described screw mandrel lower end, can rotate, this structure becomes present bascule by the fixed structure of the integral type in past, when throttle down, when touching sealing seat, the sealing lobe just stops operating, and screw mandrel still can continue by the rotation of rotatory handling to tighten downwards, so just can effectively reduce the friction of sealing lobe and sealing seat in the sealing, thereby prolong the working life of valve.
Claims (3)
1, a kind of sampling cock; comprise that valve body (1), rotatory handling (10), screw mandrel (2), sealing lobe (3) and sealing seat (5) is characterized in that: described valve body (1) is provided with and the sampling valve body (11) of valve body (1) one; wherein be provided with sampling core (8); O type circle (13) and safety cover (12) are formed, and between described safety cover (12) and the valve body (1) connection chain (9) are arranged.
2, sampling cock according to claim 1, it is characterized in that: between described screw mandrel (2) and sealing lobe (3), be provided with a sealing lobe sheath (4), described sealing lobe sheath (4) is to be enclosed within described screw mandrel (2) lower end, can rotate, described sealing lobe (3) is contained in the described sealing lobe sheath (4).
3, sampling cock according to claim 2 is characterized in that: described sealing seat (5) is provided with an annular protrusion (6), and this projection can be absorbed in the sealing lobe (7) during sealing.
