Abstract

The invention relates to a valve of a filter, in particular to a filter valve which is applicable to the filtration of the impurities in flow liquid in a filtration pipeline in the state of non-stopping of the machine. The technical proposal is that: the filter valve is mainly composed of a filter valve main body, a valve inlet and a valve outlet, the interior of a cylindrical space between the valve inlet and the valve outlet of the filter valve main body is provided with a valve core which is tightly contacted with the cylindrical space and is rotated by a direction changing wrench, the upper part is sealed by a valve top cover, a through hole is drilled in the horizontal direction of the valve core, the both sides are processed with two symmetrical arc-shaped grooves including a liquid inlet groove and a liquid outlet groove, the symmetrical positions of the horizontal position of a valve seat are drilled with a liquid inlet hole and a liquid outlet hole, a filter mesh is arranged on the liquid outlet hole, and a filtration cavity is formed between the valve seat and the space of a filter valve bottom cover. The filter valve has the advantages that the organic combination of the valve and the filter is formed, and the filter valve has simple pipeline, convenient operation, low cost and low failure rate, thereby facilitating the standardization of pipe parts.

Description

Strainer valve

One, technical field:

The present invention relates to a kind of valve of filter, particularly relate to a kind of strainer valve of the impurity of working fluid in the filter pipeline that is applicable under the stopped status not.

Two, background technology:

In large-scale and the plant equipment that runs up, commonly used to cooling water and lubricated wet goods accessory system, in order to guarantee the long-term safety running of equipment, generally all in accessory system, add fixed filter, be used for the impurity of filtering appts; Impurity in the filter needs regularly to remove, because a variety of causes of main equipment and can not request stop, so install a straight-through valve additional between the two ends of the filter of being everlasting, bypass filter, and respectively install a valve additional at the two ends of filter and be convenient to clear up filter, constitute the cleaning process of filter; The pipeline complexity, complex operation, cost is higher, the fault rate height, the installation and maintenance difficulty is big.

Three, summary of the invention:

Purpose of the present invention is exactly the above-mentioned defective that exists at prior art, provides a kind of pipeline simple, easy to operate, and cost is low, and fault rate is low, is convenient to realize the standardized strainer valve of pipe fitting.

Its technical scheme is: mainly be made up of strainer valve main body, valve import and valve outlet port, in the cylindrical space between the valve import of strainer valve main body and the valve outlet port, install and closely contact with it and can be by the spool of commutation wrench rotation, top is by the valve top seal, on the horizontal direction of spool, be drilled with a through hole, its both sides are processed with two the deep-slotted chip breaker lead channel and the liquid outlet groove of symmetry, horizontal level symmetric position at valve seat is drilled with inlet opening and fluid hole, screen pack is installed on fluid hole, and valve seat forms filter chamber with the space of filter bottom.

The plush copper of described spool bottom is provided with spacer pin, and the anglec of rotation that is used to limit spool is 90 degree to the maximum.

The invention has the beneficial effects as follows: form the combination of valve and filter, and pipeline is simple, easy to operate, cost is low, and fault rate is low, is convenient to realize the standardization of pipe fitting.

Four, description of drawings:

Accompanying drawing 1 is a structural representation of the present invention;

Accompanying drawing 2 is A-A cutaway views of the present invention;

Among the figure: the 1-reversing handle; The 2-through hole; The 3-lead channel; The import of 4-valve; The 5-spacer pin; The 6-inlet opening; The 7-filter chamber; 8-filters bottom; 9-valve top cover; The 10-valve outlet port; The 11-spool; The 12-liquid outlet groove; The 13-fluid hole; The 14-filter screen; The 15-valve seat.

Five, the specific embodiment:

1-2 in conjunction with the accompanying drawings, the invention will be further described:

Its structure mainly is by the strainer valve main body, valve import 4 and valve outlet port 10 are formed, in the cylindrical space between the valve import 4 of strainer valve and the valve outlet port 10, install and closely contact with it and can be by the spool 11 of commutation wrench 1 rotation, top is by 9 sealings of valve top cover, on the horizontal direction of spool 11, be drilled with a through hole 2, its both sides are processed with two the deep-slotted chip breaker lead channel 3 and the liquid outlet groove 12 of symmetry, the plush copper of spool 11 bottoms is provided with spacer pin 5, the anglec of rotation that is used to limit spool is 90 degree to the maximum, horizontal level symmetric position at valve seat 15 is drilled with two holes, inlet opening 6 and fluid hole 13, screen pack 14 is installed on fluid hole 13, and valve seat 15 covers 8 space formation filter chamber 7 with filter.

Its design principle is: the mode that adopts valve to combine with filter, filter of design below plug valve, through hole of processing is used to lead directly on the horizontal direction of cock, and at two deep-slotted chip breakers of the both sides of through hole square position processing, the filter of energy UNICOM below after the rotation, form the combination of valve and filter, reach the purpose of valve filter unification.

Its use principle is:

Normality figure when accompanying drawing is worked for the utility model filter, this moment, through hole 2 was in sealed condition, liquid enters filter chamber 7 by the inlet opening 6 of valve import 4 on the lead channel on the spool 11 3, valve seat 15, post precipitation is through filter screen 14 filterings impurity wherein, by fluid hole 13, liquid outlet groove 12 flow valves outlet 10, finish the sedimentation and filtration workflow of liquid again; When the needs filter rinsed, rotate reversing handle 1 on earth, making the maximum anglec of rotation under the qualification of spacer pin 5 is 90 degree, this moment through hole 2 corresponding coupling cock import 4 and valve outlet ports 10, inlet opening 6 and fluid hole 13 be by spool 11 shutoff, and filter chamber 7 is sealed by short circuit, and liquid is in pass-through state; Open filter bottom 8 and can carry out cleaning operation filter screen 14; Reverse operating can reenter normal operating conditions after finishing.

Claims
