Abstract
The utility model relates to a novel anti-clogging and anti-freeze sampling valve which comprises a hand wheel, a valve rod, a valve body, a valve rod seal, a valve pad and a valve core; the hand wheel is connected with the valve rod; the valve rod passes through the valve body, is concentric with the valve body, and is connected with the valve core; the valve body is in a cylindrical structure; one end of the valve body fixes the valve pad, the other end of the valve body is provided with a valve rod support with a seal groove and a nut, a discharge opening is arranged in the middle, and a connecting flange is arranged outside the valve body; and through the rotation of the hand wheel, the valve rod drives the valve core to have linear reciprocating motion so as to connect or disconnect a valve body cavity and the inner cavity of a container and sample the liquid in the container. When sampling liquid with high solid content, the novel anti-clogging and anti-freeze sampling valve can prevent impurities from clogging and the frost heave problem caused by the liquid left in the valve body in low-temperature environment, is simple to operate, stable and reliable to operate, has low manufacturing cost and maintenance cost, and the like.
Description
Technical field
The utility model relates to a kind of liquid sampling equipment of high solid content, particularly relates to the feed liquid sampler in a kind of northern area feces of livestock and poultry fermentation tank.
Background technology
In recent years, the feces of livestock and poultry anaerobic fermentation is produced the effective solution livestock and poultry cultivation of developing into of biogas technology and is polluted, and the exploitation clean energy resource provides technical support.In anaerobic fermentation process, sampling, the chemical examination of carrying out fermented feed liquid is the necessary control device of the normal operation of biogas engineering.Mostly the sampler that adopts is to be made up of the stopple coupon and the common valve that are arranged on the tank body at present.Because stopple coupon is slim-lined construction more, and exposes outside tank skin, has material in the pipe all the time.In the biogas engineering actual motion, exist feed liquid crust, contamination precipitation to block phenomenons such as sampling pipe valve, particularly in the biogas engineering of extremely frigid zones, owing to have material all the time in the pipe, under the winter low temperature environment, exist feed liquid and freeze, frost heave is stopped up the problem of sample tap, directly influences testings such as the normal sample examination of feed liquid, cause sweat out of control, influence the normal operation of biogas engineering.For this reason, develop anti-blocking, antifreeze sampling equipment, just particularly important to solve the disadvantage that traditional sampler exists.
The utility model content
The technical problems to be solved in the utility model is to avoid impurity obstruction sample tap in the sample tap place liquid, and guarantees that winter, sample tap did not freeze, and is applicable to the sampler of large-scale storage tank.
In order to solve the problems of the technologies described above, the purpose of this utility model provides a kind of novel anti-blocking, antifreeze sample valve, comprises handwheel 1, valve rod 2, valve body 3, valve pad 5, spool 6; Described handwheel 1 is connected with valve rod 2 and rotation synchronously; Described valve rod 2 passes valve body 3 and concentric with valve body 3, and is connected with spool 6; Described valve pad 5 is connected with valve body 3 ends, and cooperates with spool 6; The below of described valve body 3 center sections has discharging opening 10;
Described spool 6 is an inverted cone-shaped structure, and during with valve pad 5 closures, the conical surface contacts with valve pad 5, forms linear sealing;
For guaranteeing that valve rod 2 stable motions and feed liquid do not leak, and are provided with valve rod support ring 9 in the described valve body 3, and are provided with valve stem seal 4 in the valve rod support ring 9;
In order to be connected with the container pipe connecting flange, described valve body 3 outer walls are provided with joint flange 12.
Described valve body 3 is a cylinder-like structure, and an end fixedly valve pad 5, one ends is provided with valve rod support and the screw of being with seal groove, and the centre has discharging opening 10, the valve body 3 outer joint flanges that are provided with; Described spool 6 is an inverted cone-shaped structure, with the gap formation charging aperture 14 of valve pad 5; Described valve pad 5 is a flexible gasket; Described valve rod 2 is one section screwed stiff shaft, cooperates with screw on the valve seat to drive the valve head motion; Described valve stem seal 4 is " O " type rubber ring group; Described handwheel 1 is the power input mechanism that valve rod 2 rotates.
The utility model since charging aperture in container body, with liquid in container and extraneous the isolation, so after the sampling end, therefore residual liquid not in the valve body, has solved the problem of preventing freeze in winter.Simultaneously, because spool is a back taper, the sealing pair that constitutes with valve pad is linear sealing, has guaranteed the reliability of sealing, and can prevent to scab.The big I free adjustment of charging aperture has been avoided the impurity blocking problem.In addition, body cavity have anti-ly wash away, corrosion resistant O-ring seal, in Open valve moment, can protect valve body not washed away, corrode by medium.Adopt handwheel to open and close charging aperture, operate simplyr, move more reliable.
Description of drawings
Fig. 1 is an axial section of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises handwheel 1, valve rod 2, valve body 3, valve stem seal 4, valve pad 5, spool 6; Handwheel 1 directly is connected with valve rod 2 and guarantees rotation synchronously, can drive valve rod 2 rotations; Valve rod 2 nearly handwheel 1 ends have external thread 7, cooperate with the internal thread 8 of nearly handwheel 1 end on the valve body 3, realize valve rod 2 straight reciprocating motions; Be provided with valve rod support ring 9 in the valve body 3, valve stem seal 4 is " O " type rubber ring group, places in the support ring 9, guarantees that valve rod 2 stable motions and feed liquid do not leak; The below of valve body 3 center sections has discharging opening 10, communicates with valve body chamber 11; Valve body 3 outer walls are provided with joint flange 12, can be connected with the container pipe connecting flange; Valve body 3 is provided with valve seat cushion 13, is used for supporting and being connected valve pad 5; Gap between spool 6 and the valve pad 5 forms charging aperture 14.
The course of work of the present utility model: the joint flange on the valve body 3 12 is connected with the container pipe connecting flange and fixing, spool 6 closely cooperates with valve pad 5, and is positioned at container body.Rotation hand wheel 1, drive valve rod 2 rotations, spool 6 separates with valve pad 5, and container intracavity communicates with valve body chamber 11, liquid in the container then enters in the valve body chamber 11 from charging aperture 14, and from discharging opening 10 outflows, after the liquid elution volume reaches sampling amount, reverse rotation handwheel 1, spool 6 and valve pad 5 are closely cooperated, container intracavity and valve body chamber 11 are cut off, treat that the liquid in the valve body chamber 11 all flows out, promptly finish sampling work.
