Description

A kind of pottery swing check valve

Technical field

This utility model relates to a kind of pottery swing check valve.

Background technology

Ceramic form of check valve in the market is varied, and performance is different, but The most existing pottery check valve structure is complicated, poor sealing performance, and only at valve body latus rectum Locating ceramic embedded ring or valve inner the latter half is inlayed ceramic structure, top half is without ceramic junction Structure, therefore, fluid still can contact with housing when flow valve is internal, uses meeting for a long time Cause enclosure interior generation corrosion condition, affect its service life.

Utility model content

For solving above-mentioned technical problem, this utility model provides a kind of pottery swing check valve.

Pottery swing check valve of the present utility model, including two housings being fixed together, The cavity inner wall formed between said two housing is provided with pottery inner sleeve, the two ends of pottery inner sleeve Being respectively equipped with inlet and liquid outlet, the right-hand member inwall of inlet arranges internal conical surface, female cone Arranging pottery flap in face, the left end outer wall of pottery flap is arranged outside matching with internal conical surface Taper seat, the top of pottery flap connects rocking bar at right-hand member, and connecting rod is passed through on the top of rocking bar Axle is flexibly connected connecting rod, and the left end of connecting rod is fixed on housing.

Pottery swing check valve of the present utility model, the junction of said two housing is equipped with Some connecting plates arranged in pairs, are bolted between the connecting plate of adjacent two housings.

Pottery swing check valve of the present utility model, the top of described pottery flap is near right-hand member Place is provided with the fixing hole for fixing rocking bar, and the ceramic flap on the right side of fixing hole is provided with locking Hole, is inserted in lock-screw in locking hole, the bottom of described rocking bar is transversely provided with and leads to lock-screw Cross threaded screwed hole.

Pottery swing check valve of the present utility model, the left end of described connecting rod is through pottery inner sleeve It is threaded connection with housing afterwards.

Pottery swing check valve of the present utility model, described pottery inner sleeve is by two potteries half set Body is bonded.

Compared with prior art the beneficial effects of the utility model are: ceramic rotary of the present utility model Opening formula check valve structure novel, pottery inner sleeve uses monolithic construction, is separated with housing by fluid Opening, long-time use does not results in housing corrosion, and is unidirectional automatic valve, it is not necessary to any drive Dynamic device, simple in construction, volume are little, and I&M is very convenient, and all ceramic members exist Can be replaced easily after abrasion.

Detailed description of the invention

Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is made further Describe in detail.Following example are used for illustrating this utility model, but it is new to be not limited to this practicality The scope of type.

As Figure 1-4, a kind of pottery swing check valve, it is fixed together including two Housing 1, the cavity inner wall formed between said two housing 1 is provided with pottery inner sleeve 2, pottery Porcelain inner sleeve 2 be respectively arranged at two ends with inlet 3 and liquid outlet 4, the right-hand member inwall of inlet 3 Internal conical surface 5 is set, pottery flap 6, the left end of pottery flap 6 are set in internal conical surface 5 Outer wall arranges the outer conical surface 7 matched with internal conical surface 5, and the top of pottery flap 6 is close Connecting rocking bar 8 at right-hand member, the top of rocking bar 8 is flexibly connected connecting rod 10 by pitman shaft 9, even The left end of bar 10 is fixed on housing 1.

Pottery swing check valve of the present utility model, the junction of said two housing 1 is all provided with There are some connecting plates arranged in pairs 11, pass through between the connecting plate 11 of adjacent two housings 1 Bolt 12 is fixed.

Pottery swing check valve of the present utility model, the top of described pottery flap 6 is near right The fixing hole 13 for fixing rocking bar 8, the ceramic flap 6 on the right side of fixing hole 13 it is provided with at end It is provided with locking hole 14, in locking hole 14, is inserted in lock-screw 15, the bottom of described rocking bar 8 It is transversely provided with the screwed hole 16 being threaded connection with lock-screw 15.

Pottery swing check valve of the present utility model, the left end of described connecting rod 10 is interior through pottery It is threaded connection with housing 1 after set 2.

Pottery swing check valve of the present utility model, described pottery inner sleeve 2 is by two potteries half Body is bonded.

Pottery swing type check valve structure of the present utility model is novel, and pottery inner sleeve 2 is by two potteries Porcelain half body is bonded, and then fluid is separated by pottery inner sleeve 2 with housing 1, makes for a long time With not resulting in housing corrosion, and it is unidirectional automatic valve, it is not necessary to any driving means, structure Simply, volume little, connected by bolt 12 between two housings 1, I&M is unusual Convenient, all ceramic members can be replaced upon wear easily.Time specifically used, When resting, the outer conical surface 7 of pottery flap 6 coordinates with the internal conical surface 5 of pottery inner sleeve 2, place At sealing state.When fluid is flowed into by inlet 3, along with the pressure of fluid increases, pottery Flap 6 drives rocking bar 8 to shake (as shown in Figure 4) along pitman shaft 9, and now fluid normally circulates. After fluid is cut-off, pottery flap 6 leans on the gravity of self to be turned down, now due to fluid Backflow, position when also can push back static by pottery flap 6, at this moment because of the back of the body of pottery flap 6 There is the pressure of withdrawing fluid in face, so the internal conical surface 5 of pottery flap 6 and ceramic inner sleeve 2 seals Can be tightr.The design nominal pressure of pottery swing check valve of the present utility model is 0.25MPa-40MPa, it is adaptable to High Temperature High Pressure and the fluid of all strong acid and strong base severe corrosives.

The above is only preferred implementation of the present utility model, it is noted that for this skill For the those of ordinary skill in art field, in the premise without departing from this utility model know-why Under, it is also possible to making some improvement and modification, these improve and modification also should be regarded as this practicality newly The protection domain of type.
