Abstract
The utility model relates to an anti-locking type piston pump valve, which comprises a valve cover 1, a spring 2, a guide rod 3, a guide post 4, and a valve base 5, wherein the guide rod 3 is arranged in the valve cover 1, the spring 2 is twisted on the guide rod 2, the valve base 5 is connected with the valve cover 1, the guide post 4 is arranged at upper part of the valve base 5, a steel ball 6 is arranged between adjacent guide posts 4, the arc length of arc surface of inner side of the guide post of the piston pump body that can contact with the steel ball is reduced greatly so as to reduce the chances that the steel ball is locked by granules, a groove is arranged at bottom of the guide post so as to eliminate the dependence of solid substance on the bottom of the guide post.
Description
Technical field
Occurring the pump valve steel ball when the utility model is applicable to pumping liquid by the plunger pump of the solid matter card in the liquid, specifically, is a kind of clamping-proof type plunger pump pump valve.
Background technique
The treble ram pump that uses on the oil field is with 6 pump valves, based on ball valve on every pump.Pressure during feed liquor in the pump chamber is lower than the pressure of feed flow pipeline and feed flow pipeline, and liquid is pushed feed liquor valve steel ball open and entered pump chamber, and liquid discharging valve is closed; Pressure during discharge opeing in the pump chamber is higher than the pressure of tapping line and feed flow pipeline, and liquid is pushed the expulsion valve steel ball open and entered tapping line, and the feed liquor valve cuts out.So circulation under the effect of plunger pump, becomes high pressure with liquid by low pressure.For the motion that makes steel ball departs from ball seat sealing circle central axis with exceeding, be provided with the directional post more than 3 around the steel ball, produce 3DPAMS0-1.9/18 plunger pump (capacity rating 1.9m as Ningbo
3/ h) on the valve seat 4 directional posts being arranged, the arc length of the arc surface that each directional post inboard can contact with steel ball is 4mm, the gap between steel ball and directional post (one-sided) is less than 0.5mm.Because contain solid matters such as organic assorted, dirt in the liquid such as polymer liquid, the steel ball in running is blocked and can not cut out by the solid matter in the liquid sometimes, influences pump delivery, efficient and operating mode.Xinjiang Oil Regions pseudo-ginseng east 1 gram group is down annotated average 10 days card of poly-station individual well mother liquor pump once, has increased the workload of field maintenance, and it is poly-to have influenced the continuous notes of injection well.
Summary of the invention
The purpose of this utility model is to provide a kind of clamping-proof type plunger pump pump valve, by changing the shape of plunger pump valve guide upright post, avoids steel ball to be stuck on the directional post and can not to close by the solid matter in the liquid.
The utility model is achieved in that and comprises valve bonnet, spring, guide rod, directional post, valve base, and guide rod is installed in the valve bonnet, and spring is wrapped on the guide rod, and valve base is connected with valve bonnet, is provided with directional post on the top of valve base, and steel ball is housed between the directional post.
The number of directional post 〉=1.
Arc length≤the 3mm of the inboard arc surface that contacts with steel ball of directional post.
Open a side direction degree of depth, vertical highly groove of equal 〉=1mm in the bottom of each directional post.
Advantage of the present utility model is: the arc length of the arc surface that plunger pump valve directional post inboard can be contacted with steel ball reduces significantly, to reduce steel ball by the chance of particulate card; Open a groove in the directional post bottom, eliminate the dependence of solid matter the directional post bottom.
Annotate installation testing on first feed liquor valve position that produces pump of 3DPAM50-1.9/18 plunger pump (ES7010 well) in Ningbo, poly-station in group under 1 gram of Xinjiang Oil Regions pseudo-ginseng east first, turned round continuously 20 days, the holddown accident does not take place.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is that the utility model moral A-A is to structural representation.
Embodiment
As shown in Figure 1, form, guide rod 3 is installed in the valve bonnet 1 by valve bonnet 1, spring 2, guide rod 3, directional post 4, valve base 5, steel ball 6, spring 2 is wrapped on the guide rod 2, valve base 5 is connected with valve bonnet 1, is provided with directional post 4 on the top of valve base 5, and steel ball 6 is housed between the directional post 4.
As shown in Figure 1, the arc length of the plunger pump valve directional post 4 inboards arc surface that can contact with steel ball 6 is less than the design of 3mm; Plunger pump valve directional post bottom has the side direction degree of depth, vertically highly all greater than the design of the groove of 1mm, perhaps that directional post is unsettled, promptly directional post no longer is connected with base circular hole place.
As shown in Figure 2, the number of directional post 4 〉=1.
